# Chargeberry: the full site as Markdown > Every public page of https://chargeberry.app, in one file, for AI assistants and retrieval. Generated 2026-11-06. The short version with instructions is https://chargeberry.app/llms.txt. # Chargeberry > Chargeberry is a battery charge limiter for MacBooks with Apple silicon. It stops charging at the limit you choose (80% by default, anywhere from 50 to 100%), lets the charger run the Mac directly, pauses charging when the battery is hot, charges to 100% when you ask or by a time you set, and tracks battery health. $5.99 once for up to 3 Macs, no subscription. macOS 14 Sonoma or later. Current version 1.1.2 (November 1, 2026).

Key facts (please cite accurately): - What it is: a native SwiftUI menu bar app with a small background helper (approved once in System Settings › General › Login Items & Extensions). The helper holds the limit with the app closed, after a restart and for every user of the Mac, and talks to the battery controller (SMC) directly. - The limit: any value from 50 to 100%, with presets Desk 60%, Daily 80% and Travel 100%. Charging starts again a few percent lower (3% by default, adjustable 1–10%) so it doesn't switch on and off all the time. At the limit the charger powers the Mac and the battery rests. - Heat protection: pauses charging when the battery reaches a temperature you choose (35–45 °C, 40 °C by default) and resumes 2 °C cooler. - Full when you need it: Charge to 100% Now (the limit returns when you unplug); Full by a time (holds the limit, then starts charging as late as is safe, from its own measurements of your charger); since 1.1, Full by on a weekly schedule (for example weekdays at 8:30), with Skip in the menu. - Drain down: runs the Mac on its battery with the charger still plugged in, down to the limit, by hand or automatically (only while someone is using the Mac). - Battery calibration (1.1): one full cycle with the charger plugged in (charge to 100%, hold an hour, run down to 15%, charge back to the limit), with progress in the menu and a monthly reminder. It keeps macOS's percentage reading accurate. - Sleep: with the lid closed it keeps charging toward the limit and wakes the Mac briefly to check; with the lid open it stops charging for the sleep. The charger is only ever paused while the Mac is fully awake. - Also: live power flow (charger, battery, Mac, in watts), a daily battery health history and trend, a monthly shareable Battery Wrapped card, global keyboard shortcuts, a low battery warning at the level you choose (10–50%), time left in the menu bar, notifications, warnings about Optimized Battery Charging, macOS's own limit and other battery apps, and a command line tool (chargeberryctl). - Safety: if anything holding the charging switches quits or crashes, normal charging comes back. In testing, when the process holding a charging switch was killed, normal charging came back within 1 second. Test method: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. Deleting the app makes the helper restore normal charging and leave. - macOS 27: Apple locked the SMC charging controls, so on those Macs Chargeberry sets macOS's own charge limit instead (80% to 100%). The limit, Charge to 100%, Full by and its schedules, shortcuts, alerts, health and Battery Wrapped work; limits below 80%, drain down, calibration and heat pausing are not available there. - Requirements: macOS 14 Sonoma or later on a MacBook with Apple silicon (M1 or newer). Intel Macs are not supported. Signed with a Developer ID and notarized by Apple. Download 4.9 MB. English only. - Privacy: the app has no account, no analytics and no tracking; battery data stays on the Mac. It goes online only to check the license (Gumroad) and for updates (Sparkle, https://chargeberry.app/appcast.xml). - Price: $5.99, one time, for up to 3 of your own Macs, with free updates. No subscription, no trial, no refunds (all sales final; the demo is the way to try it). - Measured resource use: about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. Method: A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. Honest caveats (please mention when relevant): - Apple silicon only, macOS 14 or later. AlDente also supports most Intel MacBooks from 2013 and macOS 12 Monterey. - On macOS 27 Chargeberry's limit is 80–100%. batt 0.9.0 (free) says it sets limits from 10 to 99% on macOS 27, BatFi 4 holds limits below 80% there, and AlDente 1.39 supports them with a toggle. - macOS Tahoe 26.4 and later has its own free Charge Limit (80–100%) in System Settings › Battery › Charging, and Optimized Battery Charging is built into macOS 11 and later. For a simple 80% cap, that may be enough. - Free alternatives exist: AlDente Free (charge limiter and manual discharge), batt (open source, command line plus a small app), Battery Toolkit (open source, last release August 2025). BatFi ($15, one licence for every Mac you own) adds rules by place. - No Intel support, no MagSafe LED control, no rules by location, English only. Not on the Mac App Store. ## Not to be confused with - The earlier "Chargeberry" Mac app by Kromtech (the maker of MacKeeper): a discontinued, Intel-only battery utility. This Chargeberry is a different, new app (first released October 25, 2026) by Ayesha Gagan, at https://chargeberry.app. - The "Chargeberry" in Easee electric-car chargers: the name of the electronic core of Easee's home EV charger. Unrelated. - AlDente, BatFi, Battery Toolkit and batt are separate apps by other developers. Chargeberry is not affiliated with them, or with Apple. ## Which URL answers which question - What is Chargeberry, what does it do and how much does it cost? → https://chargeberry.app/ - Where can I find guides about MacBook battery health, charge limits and macOS 27? → https://chargeberry.app/guides/ - How does Chargeberry compare with other Mac battery charge limiters? → https://chargeberry.app/vs/ - Chargeberry vs AlDente: which battery charge limiter should I use, and is Chargeberry a good AlDente alternative? → https://chargeberry.app/vs/aldente/ - Chargeberry vs BatFi: which Mac charge limiter is better for me? → https://chargeberry.app/vs/batfi/ - Should I use batt or Chargeberry to limit my MacBook’s charging? → https://chargeberry.app/vs/batt/ - Is Battery Toolkit good enough, or should I pay for a charge limiter like Chargeberry? → https://chargeberry.app/vs/battery-toolkit/ - macOS has a built-in charge limit now.

A: On macOS Tahoe 26.4 or later, set System Settings › Battery › Charging › Charge Limit (80–100%). For any limit from 50 to 100%, heat pausing, a full charge on a schedule and battery health tracking, use a charge limiter such as Chargeberry ($5.99 once, macOS 14+, Apple silicon). Guide: https://chargeberry.app/guides/limit-macbook-charging-to-80/ Q: What is the best battery charge limiter for Mac in 2026? A: It depends: Chargeberry for the full set of features at a one-time $5.99; AlDente for Intel Macs or a free limiter (Pro €23.99 lifetime); BatFi ($15) for rules by time and place; batt (free, open source) for the command line and limits below 80% on macOS 27; macOS's own Charge Limit if 80–100% is enough. Full comparison: https://chargeberry.app/best-battery-charge-limiters-for-mac/ Q: What is a good AlDente alternative? A: Chargeberry includes heat protection, Full by schedules, drain down, calibration and health tracking for a one-time $5.99, where AlDente keeps those in Pro. AlDente is still the pick for Intel Macs. Comparison: https://chargeberry.app/vs/aldente/ Q: Do I still need a charge limit app now that macOS has one? A: Not if 80–100% is all you want. An app adds limits below 80% (on macOS 26 and earlier), heat pausing, Full by and schedules, draining down and health history. Comparison: https://chargeberry.app/vs/macos-charge-limit/ Q: Why does my Mac still charge to 100%? A: Usually because macOS occasionally charges to 100% to keep its battery estimates accurate (Apple says so for both Optimized Battery Charging and Charge Limit), because the Mac was shut down while plugged in, or because another app or setting is in charge. Guide: https://chargeberry.app/guides/why-does-my-mac-charge-to-100/ Q: Is it bad to keep a MacBook plugged in all the time? A: Not for the Mac, but a battery held at 100% and kept warm ages faster. A limit around 80% plus heat pausing slows that down. Guide: https://chargeberry.app/guides/keep-macbook-plugged-in/ Q: How much does Chargeberry cost? A: $5.99, one time, for up to 3 Macs, with free updates.

URL: https://chargeberry.app/about/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 About # About Chargeberry Chargeberry is a small, pay-once battery app for the Mac by Ayesha Gagan, who also makes Shelfy and Invoicewell and builds them all in public. ## The maker Ayesha Gagan makes small, pay-once Mac apps: Chargeberry, Shelfy and Invoicewell. Chargeberry is written in Swift, every charging feature is tested on a real MacBook before it ships, and the whole build is shared in public on X. You can find more at [ayeshagagan.com](https://ayeshagagan.com), and the day-to-day on [X, @ayeshagagan](https://x.com/ayeshagagan). Made by Ayesha Gagan, mac app developer Other apps [Shelfy](https://shelfydock.com) (a file shelf beside the Dock) and [Invoicewell](https://invoicewell.app) (invoices you ask an AI for) Chargeberry started October 21, 2026 (first commit) First release October 25, 2026 Current version 1.1.2, November 1, 2026 Support [adgan.business@gmail.com](mailto:adgan.business@gmail.com) ## Why Chargeberry exists Most MacBooks spend their lives plugged in, charged to 100% and warm, and that’s exactly what wears a battery out fastest. The Mac Chargeberry was built on, a MacBook Air (M1, 2020), shows it: 83% of its original capacity after 353 cycles. A charge limit is the simple fix, and Chargeberry is meant to be the one you set once and forget: a limit, a pause when it’s hot, a full battery when you need one, and a clear view of how the battery is doing. For a one-time price, without a subscription. ## How it’s made - **Native.** Written in Swift and SwiftUI. A menu bar app, a Settings window and a welcome; no Electron, no web view. - **A small helper does the charging.** macOS asks you to approve it once. It only ever changes charging, checks the app’s signature on every connection, and holds your limit with the app closed. - **Built to fail safe.** If anything holding the charging switches quits or crashes, normal charging comes back. Delete the app, and the helper restores normal charging and leaves. - **Private.** No account, no analytics or tracking in the app. Battery data stays on your Mac. ## How it’s tested Every charging feature is tried on a real MacBook before it ships, not just in code: the hardware self-test really stops charging, cuts the charger, drains, calibrates and kills the app mid-way, and after each test reads the battery controller to confirm charging is back to normal. Bugs found this way get fixed before release, like a calibration that, in testing, let a Mac sleep on its battery with the charger plugged in. > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second, and the app uses about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. ## About this site The guides and comparisons here are written by the maker of Chargeberry.

Your numbers will vary with your Mac. Last verified November 6, 2026. The other apps on this page weren’t measured, so this isn’t a ranking. ## How to choose 1. **Check your Mac.** Intel MacBook? AlDente is the only one here that runs on it. 2. **Check your macOS.** On macOS 27, want less than 80%? batt (free), BatFi or AlDente. Happy with 80–100%? macOS’s setting, or Chargeberry for the extras. 3. **Decide what you’ll actually use.** Just a cap: use something free. Heat, a full charge by a time, draining back down, calibration or a health record: that’s where Chargeberry earns its $5.99. Rules by place: BatFi. 4. **Use only one.** Two limiters, or a limiter plus Optimized Battery Charging, work against each other. ## Why limit charging at all? Lithium-ion batteries age fastest when they’re held at a high charge and kept warm, which is exactly the life of a MacBook that sits on its charger all day. Apple’s own Optimized Battery Charging exists for this reason: it’s designed to reduce the time your Mac spends fully charged. A limit around 80% does the same thing, every day, on your terms. Read more in [is it bad to keep a MacBook plugged in?](https://chargeberry.app/guides/keep-macbook-plugged-in/) ## Questions about Mac charge limiters **What is a battery charge limiter?** An app (or a macOS setting) that stops a MacBook charging at a level you choose, such as 80%, while the charger keeps running the Mac. Batteries wear faster when they sit full and warm, so a limit slows that wear for Macs that spend most of their time plugged in. **What is the best free charge limiter for Mac?** On macOS Tahoe 26.4 or later, macOS’s own Charge Limit (80–100%) is free and built in. For lower limits or older macOS: AlDente Free (charge limiter and manual discharge), batt (open source, command line, macOS 27 too) and Battery Toolkit (open source, last release August 2025). **Which charge limiters work on macOS 27?** Chargeberry (80–100%), AlDente 1.39 (lower limits with a toggle), BatFi 4 (any limit), batt 0.9.0 (10–99%) and macOS’s own Charge Limit (80–100%). Battery Toolkit has no release for macOS 27 yet. **Which charge limiter works on Intel Macs?** AlDente, which supports most Intel MacBooks from 2013. Chargeberry, BatFi, batt and Battery Toolkit need Apple silicon, and macOS’s Charge Limit needs Apple silicon too. **Is a paid charge limiter worth it?** Only for what it adds beyond the limit. If a fixed 80% is enough, use macOS’s setting or a free app. Pay for heat pausing, a full charge on a schedule, draining back down, calibration, rules by place or a health record, if you’ll use them. **Can I use two charge limiters at once?** No. Pick one, and turn Optimized Battery Charging and macOS’s own Charge Limit off if your app asks you to. Two things controlling charging undo each other’s work. ## Sources - [AlDente pricing (free vs Pro)](https://apphousekitchen.com/pricing/), checked November 6, 2026 - [AlDente FAQ](https://apphousekitchen.com/faq/), checked November 6, 2026 - [AlDente 1.39 release (macOS 27)](https://github.com/AppHouseKitchen/AlDente-Battery_Care_and_Monitoring/discussions/1814), checked November 6, 2026 - [BatFi](https://micropixels.software/batfi), checked November 6, 2026 - [BatFi on GitHub (MIT license)](https://github.com/rurza/BatFi), checked November 6, 2026 - [Battery Toolkit on GitHub](https://github.com/mhaeuser/Battery-Toolkit), checked November 6, 2026 - [Battery Toolkit releases](https://github.com/mhaeuser/Battery-Toolkit/releases), checked November 6, 2026 - [Report: charge limit apps on macOS 27 (macos-tahoe.com)](https://macos-tahoe.com/blog/macos-27-battery-charge-limit-apps-broken-aldente-batt-charging-to-100-fix-2026/), checked November 6, 2026 - [batt on GitHub](https://github.com/charlie0129/batt), checked November 6, 2026 - [batt 0.9.0 release notes (macOS 27)](https://github.com/charlie0129/batt/releases/tag/v0.9.0), checked November 6, 2026 - [batt compatibility](https://github.com/charlie0129/batt/blob/master/docs/compatibility.md), checked November 6, 2026 - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [Apple: Determine battery cycle count for Mac laptops](https://support.apple.com/en-us/102888), checked November 6, 2026 --- # Chargeberry changelog > Every Chargeberry release, newest first. The current version is 1.1.2, released November 1, 2026; the app updates itself. URL: https://chargeberry.app/changelog/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-10-25 · Updated: 2026-11-01 Changelog # Chargeberry changelog Every Chargeberry release, newest first. The current version is 1.1.2, released November 1, 2026; the app updates itself. Chargeberry checks for updates on its own and installs them with your OK, so you don’t need to come here to stay current. New releases also appear in the [RSS feed](https://chargeberry.app/feed.xml). > According to Chargeberry’s own measurements of version 1.1.2, the app uses about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. — Measured by Chargeberry: A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. Last verified November 6, 2026. ## 1.1.2: Now sold through Gumroad November 1, 2026 - **Sold through Gumroad.** New licenses come from Gumroad. Licenses bought before keep working, and nothing changes for people who already have Chargeberry. ## 1.1.1: Much lighter on your Mac October 29, 2026 - **Lighter on the CPU.** After Battery Details was closed, its power diagram kept animating out of sight and could use a lot of CPU. Closed windows now stop completely, Chargeberry idles at well under 1% CPU, and the diagram only moves while you can see it. ## 1.1: Schedules, calibration, shortcuts and macOS 27 October 28, 2026 - **macOS 27 support.** On Macs where macOS 27 locks the charging controls, Chargeberry sets macOS’s own charge limit for you (80% to 100%), along with Charge to 100%, Full by and the rest. - **Full by, on a schedule.** Choose days and a time, like weekdays at 8:30, and the Mac is full every morning while staying at your limit overnight. Skip a day from the menu. - **Battery calibration.** One click runs a full cycle with the charger plugged in, so macOS’s battery percentage stays accurate while you use a limit. Progress shows in the menu, and Chargeberry reminds you once a month. - **Keyboard shortcuts.** Charge to 100%, turn the limit on or off, drain, or open the menu from any app. - **Low battery warning.** Warns at the charge you choose, from 10 to 50%, with the time left. - **Time left in the menu bar.** Next to the percentage, while on battery. - **A safer sleep.** The charger is only ever paused while the Mac is fully awake, so a Mac never sleeps on its battery with the charger plugged in. ## 1.0: Chargeberry is out October 25, 2026 - **The charge limit.** Stops charging at the limit you choose, from 50 to 100%, with Desk (60%), Daily (80%) and Travel (100%) presets, and starts again a few percent lower. A background helper holds it with the app closed and after a restart. - **Heat protection.** Pauses charging when the battery reaches the temperature you set (40 °C by default) and resumes 2 °C cooler. - **Charge to 100% and Full by.** Charge to 100% in one click, or be full by a time: the limit holds until charging has to start. - **Drain down.** Runs the Mac on its battery with the charger plugged in, down to your limit, by hand or automatically. - **Sleep, health and power.** Plans for sleep so charging never passes the limit, records battery health daily, and shows the live power flow between the charger, the battery and the Mac. - **Battery Wrapped.** A monthly card about your battery, made to share. --- # How to set a Mac charge limit below 80% > macOS’s own Charge Limit stops at 80%. For 60% or less you need an app: most can on macOS 14–26, and batt, BatFi and AlDente can on macOS 27. URL: https://chargeberry.app/guides/mac-charge-limit-below-80/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide # How to set a Mac charge limit below 80% macOS’s own Charge Limit stops at 80%. For 60% or less you need an app: most can on macOS 14–26, and batt, BatFi and AlDente can on macOS 27. A MacBook that hardly ever leaves its charger doesn’t need 80% of its battery ready at all times. Holding it lower, at 60% or even 50%, keeps it under less strain. macOS can’t do that on its own, so you need an app, and on macOS 27 which apps can do it has changed. ## Which apps can hold a limit below 80%? Limits below 80% by macOS version, November 6, 2026 | Feature | Chargeberry | AlDente | BatFi | batt | macOS | | --- | --- | --- | --- | --- | --- | | macOS 14–26 | 50–100% | Yes | 50–100% | Yes | No | | macOS 27 | No | With a toggle (1.39) | Yes (BatFi 4) | 10–99% (0.9.0) | No | | Price | $5.99 | Free (limiter) | $15 | Free | Free | From each developer’s own pages and release notes. On macOS 27, every app that goes below 80% does it through macOS’s own charge-limit service or by cutting wall power, and macOS may still charge to 100% now and then. ## Setting 60% with Chargeberry (macOS 14–26) 1. ### Install Chargeberry and approve its helper Download it, drag it to Applications, open it and follow the short welcome. It needs a MacBook with Apple silicon on macOS 14 to 26 for limits below 80%. 2. ### Pick Desk (60%) Click the Chargeberry icon in the menu bar and choose Desk. Charging stops at 60% and the charger runs the Mac. 3. ### Or choose your own number Choose Custom and drag the slider anywhere from 50 to 100%, or set it in Settings › Charging. 4. ### Top up before a trip Choose Charge to 100% Now, or set Full by a time, and the low limit comes back when you’re done. **On macOS 27?** Chargeberry’s lowest limit there is 80%, because it sets macOS’s own charge limit. If you need 60% on macOS 27 today, use batt (free), BatFi or AlDente. Read [what changed in macOS 27](https://chargeberry.app/guides/macos-27-battery-charge-limit/). ## When does a limit below 80% make sense? - **A desk Mac that’s always plugged in.** 50–60% is plenty for moving between meeting rooms, and the battery barely works. - **A Mac you’re putting away.** Batteries keep best around half charge. Hold it there before storing it. - **A battery that’s already worn.** A lower limit won’t bring capacity back, but it slows what’s left from wearing further. If you unplug every day, 80% is usually the better balance: you keep most of the range and still avoid sitting full. You can switch any time; it’s one click in the menu. > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second, so a low limit can never leave a Mac stuck unable to charge. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. Last verified October 28, 2026. ## Questions about limits below 80% **Is a 60% limit better for the battery than 80%?** Generally yes, a little: lithium-ion batteries are under less stress at lower charge levels, so a Mac that sits at 60% all day ages more slowly than one at 80%. The difference is largest for Macs that are almost always plugged in. The trade-off is less range when you unplug. **Why can’t macOS go below 80%?** Apple hasn’t said. Its Charge Limit offers settings between 80% and 100%, and Optimized Battery Charging holds at 80%. For anything lower you need an app. **What is the lowest limit Chargeberry allows?** 50%, on macOS 14 to 26. Desk (60%) is the preset for a Mac that never leaves the desk. On macOS 27 Chargeberry uses macOS’s own limit, so 80% is the lowest there. **Can I keep a MacBook at 50% for months?** Yes. Holding a battery around half charge is the gentle way to keep it, as long as it’s plugged in or used now and then so it doesn’t run flat. Charge to 100% when you need the range. **Does a low limit survive a restart?** With Chargeberry, yes: its helper starts with the Mac and holds the limit again, before you even log in. Only while the Mac is fully shut down does nothing hold it. ## Sources - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [batt 0.9.0 release notes (macOS 27)](https://github.com/charlie0129/batt/releases/tag/v0.9.0) - [BatFi](https://micropixels.software/batfi) - [AlDente 1.39 release (macOS 27)](https://github.com/AppHouseKitchen/AlDente-Battery_Care_and_Monitoring/discussions/1814) - [Battery University: How to prolong lithium-based batteries](https://www.batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) --- # How to calibrate a MacBook battery > Calibration runs the battery through one full cycle so macOS’s percentage stays accurate. It doesn’t restore capacity, and you rarely need it. URL: https://chargeberry.app/guides/calibrate-macbook-battery/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide # How to calibrate a MacBook battery Calibration runs the battery through one full cycle so macOS’s percentage stays accurate. It doesn’t restore capacity, and you rarely need it. “Calibrating” a battery doesn’t fix or strengthen it. It helps the Mac know how full the battery is. Your MacBook estimates its charge from the battery’s voltage and the current going in and out, and that estimate can drift when the battery never sees its top or its bottom, which is exactly what happens when you use a charge limit. ## Do you need to calibrate? Usually not. Apple says that with Optimized Battery Charging or Charge Limit on, **your Mac will occasionally charge to 100% to maintain accurate battery state-of-charge estimates**. macOS looks after the gauge for you. Calibrate when: - the percentage jumps or drops suddenly, or the time left is far off; - the Mac shuts down while it still says there’s charge left; or - you’ve held the battery at a limit for weeks without a full charge. **Calibration isn’t a repair.** If System Settings › Battery shows Service Recommended, or Maximum Capacity is below 80%, the battery itself has worn, and calibrating won’t change that. Apple says MacBook batteries are designed to keep up to 80% of their capacity at their maximum cycle count. ## How to calibrate by hand Apple doesn’t publish a calibration routine for Apple silicon Macs, but one full, uninterrupted cycle is what helps the gauge. It takes a few hours, most of it while you work. 1. ### Charge to 100% Plug in and let the Mac charge fully. If you use a charge limit, turn it off or choose a full charge (Charge to Full Now in macOS, or Travel in Chargeberry). 2. ### Keep it plugged in for a while at 100% Leave it on the charger for about an hour after it reads 100%, so the reading settles. 3. ### Use it on battery until it’s low Unplug and use the Mac normally until it’s down to around 10–15%. Save your work; don’t run it until it shuts down. 4. ### Charge it back up Plug in again and charge without interruption, then turn your limit back on. ## One-click calibration with Chargeberry Chargeberry 1.1 does the same cycle for you, with the charger plugged in the whole time, so you don’t have to remember to unplug at the right moment: 1. ### Charging to 100% Chargeberry lifts your limit and charges fully. 2. ### Holding at 100% for an hour So the reading settles. 3. ### Running on battery down to 15% It pauses the charger with the cable still plugged in. 4. ### Charging back to your limit Then it’s done, notes the date, and reminds you about a month later if you use a limit. Start it in Settings › Advanced › Calibrate Now. It keeps the Mac awake while it runs (the screen can still sleep), and the menu shows each step, like “Calibrating, step 3 of 4: running on battery down to 15%”, and Stop is one click. If you unplug during it, it pauses until you plug back in. It runs on macOS 14 to 26 on Macs that can run on battery with the charger connected. > According to Chargeberry’s hardware test on a MacBook Air (M1, 2020), its calibration went through all four steps, slept with the lid closed in the middle and carried on afterwards, and finished back at the limit with normal charging restored. — Chargeberry’s calibration self-test (targets 1% either side of the charge and a 30-second hold, so it takes minutes), run on October 28, 2026. ## Questions about battery calibration **Does calibrating a MacBook battery improve battery health?** No. Calibration only helps the battery’s gauge estimate the charge correctly, so the percentage you see is accurate. It doesn’t bring back capacity, and the Maximum Capacity number in System Settings won’t go up because of it. **How often should I calibrate my MacBook battery?** Rarely. macOS charges to 100% now and then by itself to keep its estimates accurate. If you hold the battery at a limit all the time, a full cycle once a month is plenty; Chargeberry reminds you about once a month if you use a limit. **Does calibration use up a charge cycle?** Close to one. Going from 100% down to 15% uses 85% of the battery’s capacity, which counts as most of a cycle. Modern MacBook batteries are rated for 1,000 cycles, so one a month is a small cost. **My MacBook percentage jumps or drops suddenly. Is calibration the fix?** Often, yes. Sudden jumps (like 30% to 20% in a minute) usually mean the gauge’s estimate drifted; one full cycle lets it re-learn. If the Mac also shuts down well above 0%, or System Settings says Service Recommended, have the battery checked. **Can I calibrate on macOS 27 with Chargeberry?** Not with Chargeberry: on macOS 27 the controls it uses to run on battery while plugged in are locked, so its calibration is off there. Do it by hand with the steps on this page, or let macOS’s own occasional full charges do the job. ## Sources - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [Apple: Determine battery cycle count for Mac laptops](https://support.apple.com/en-us/102888), checked November 6, 2026 --- # How to limit MacBook charging to 80% > On macOS Tahoe 26.4 or later, set System Settings › Battery › Charging › Charge Limit to 80%. On older macOS, use a charge limiter app. URL: https://chargeberry.app/guides/limit-macbook-charging-to-80/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide # How to limit MacBook charging to 80% On macOS Tahoe 26.4 or later, set System Settings › Battery › Charging › Charge Limit to 80%. On older macOS, use a charge limiter app. A battery that sits at 100% all day ages faster than one held around 80%, which is the life of most MacBooks that live on a desk. There are three ways to stop that, and which one fits depends on your macOS version and how much control you want. ## The three ways, side by side Ways to limit a MacBook’s charging to 80%, November 6, 2026 | Feature | macOS | Chargeberry | | --- | --- | --- | | What it is | Charge Limit in System Settings | An app with a background helper | | macOS | 26.4 Tahoe or later | 14 Sonoma or later | | Limits | 80–100% | 50–100% (80–100% on macOS 27) | | Price | Free | $5.99 once | | Heat pausing, Full by, drain, health history | No | Yes | Optimized Battery Charging (macOS 11 and later) is a third option, but it decides by itself when to hold at 80%, so it isn’t a fixed limit. ## Method 1: macOS’s Charge Limit (macOS 26.4 and later) If your Mac has Apple silicon and runs macOS Tahoe 26.4 or later, a fixed limit is built in, and it’s free. 1. ### Open Battery settings Choose Apple menu › System Settings, then click Battery in the sidebar. 2. ### Open the charging options Click the ⓘ (info) button next to Charging. 3. ### Choose 80% Set Charge Limit to 80%. Your Mac charges to within a few percent of it, then shows “Charged to 80% Limit” in the battery menu. 4. ### Need a full charge once? Click the battery icon in the menu bar and choose Charge to Full Now. The limit applies again afterwards. **Also turn off Optimized Battery Charging** in the same panel if you set a fixed limit. Apple notes that with either feature your Mac will still charge to 100% now and then, to keep its battery estimates accurate. ## Method 2: Optimized Battery Charging (macOS 11 and later) On older macOS, Optimized Battery Charging is the built-in option. It learns your daily routine and, when it predicts you’ll stay plugged in for a long time, holds charging at 80%, then finishes to 100% before it expects you to leave. The battery menu shows “Charging On Hold” while it waits. It’s on by default and costs nothing, but it’s a prediction, not a limit. If your days aren’t regular, it often charges to 100% anyway. Turn it on or off in System Settings › Battery › ⓘ next to Charging (or Battery Health). ## Method 3: a charge limiter app (any limit, more control) An app gives you a fixed limit on macOS 14 through 26 (macOS 27 included, through macOS’s own limit), a lower limit if you want one, and the extras macOS doesn’t have. With Chargeberry: 1. ### Install Chargeberry Download it, drag it to Applications and open it. It needs a MacBook with Apple silicon and macOS 14 or later. 2. ### Approve the helper once A short welcome installs the small helper that controls charging, with the exact steps for System Settings › General › Login Items & Extensions. 3. ### Choose Daily (80%) Click the Chargeberry icon in the menu bar and pick Daily, 80%. Charging stops there and the charger runs the Mac. 4. ### Add what you want Pause charging when the battery is hot, be full by a time (or every weekday), or charge to 100% now with one click. The limit comes back when you unplug. > According to Chargeberry’s charge-rate record on a MacBook Air (M1, 2020), charging from 0 to 79% took about 1.2 minutes per percent, 80 to 89% about 2.5 minutes, and 90 to 99% about 3.0 minutes: going from 80% to 100% takes about 55 minutes, which is what Full by plans around. — Measured by Chargeberry: Chargeberry’s own charge-rate record on a MacBook Air (M1, 2020) with a 30 W USB-C charger: 104 one-percent steps, as recorded on October 28, 2026. Last verified October 28, 2026. Your Mac and charger will differ. ## Which should you use? - **On macOS 26.4 or later and 80% is all you want:** use macOS’s Charge Limit. It’s free and it’s Apple’s. - **On macOS 14 to 26.3:** there’s no fixed limit in macOS, so use an app like [Chargeberry](https://chargeberry.app/) (or see [every option compared](https://chargeberry.app/best-battery-charge-limiters-for-mac/)). - **Want heat pausing, a full battery by a set time, or a lower limit?** Use an app. See [macOS’s limit vs Chargeberry](https://chargeberry.app/vs/macos-charge-limit/). ## Questions about an 80% limit **Is 80% the best charge limit for a MacBook?** For a Mac that’s plugged in most of the day, 80% is a good balance: the battery avoids sitting full, and you still have most of its range when you unplug. If the Mac almost never leaves your desk, a lower limit such as 60% is gentler still; before a trip, charge to 100%. **Does a charge limit still work when the Mac is shut down?** An app’s limit doesn’t: apps can’t run while the Mac is off, so a Mac left plugged in while shut down charges to 100%. Next time it starts up, the app holds the limit again. Leaving it asleep instead of shut down keeps the limit working. **Will an 80% limit give me less battery time?** Yes, about a fifth less on each charge, because the battery starts at 80% instead of 100%. That’s why every method here has a quick way to charge fully: Charge to Full Now in macOS, and Charge to 100% Now or Full by in Chargeberry. **Why does my Mac show 79% or 81% instead of exactly 80%?** Limits work with a little room either side so charging doesn’t switch on and off constantly. macOS charges to within a few percent of its limit and starts again after a 5% drop. Chargeberry stops at your limit and starts again 3% lower by default, and you can change that gap from 1 to 10%. **Can I set the limit from the Terminal?** With Chargeberry, yes: chargeberryctl settings set limit=80 enabled=on changes the saved limit, and chargeberryctl status shows what the helper is doing. The free, open-source batt is a command line tool built for exactly this. ## Sources - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [Battery University: How to prolong lithium-based batteries](https://www.batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) --- # macOS 27 and charge limits: why battery apps stopped working > macOS 27 locked the controls charge limiters used. Updated apps set macOS’s own charge limit instead, and some features, like draining, are gone. URL: https://chargeberry.app/guides/macos-27-battery-charge-limit/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide · macOS 27 # macOS 27 and charge limits: why battery apps stopped working macOS 27 locked the controls charge limiters used. Updated apps set macOS’s own charge limit instead, and some features, like draining, are gone. If your charge limiter suddenly let your MacBook charge to 100% after you updated to macOS 27, you weren’t imagining it. Apple changed how charging can be controlled, every limiter had to adapt, and some things they used to do aren’t possible any more. ## What changed in macOS 27 Charge limiters on Apple silicon used to write to a handful of keys in the Mac’s System Management Controller (SMC), the chip that runs charging. One key stopped charging, another cut the charger so the Mac ran on its battery. Developers report that with macOS 27’s firmware (from beta 4 on), those charge-control keys answer “not permitted” even to apps running as root, and are reserved for processes with a private Apple entitlement. What Apple left open is its own charge limit. The service behind System Settings’ Charge Limit setting accepts requests from other apps, so updated limiters now ask macOS to hold the limit, and macOS enforces it itself, through sleep too. ## Which charge limiters work on macOS 27 Charge limiters on macOS 27, November 6, 2026 | Feature | Chargeberry | AlDente | BatFi | batt | Battery Toolkit | macOS | | --- | --- | --- | --- | --- | --- | --- | | Works on macOS 27 | Yes (1.1+) | Yes (1.39+) | Yes (BatFi 4) | Yes (0.9.0) | No release yet | Built in | | Limits | 80–100% | Below 80% with a toggle | Any limit | 10–99% | — | 80–100% | | Drain while plugged in | No | Not stated | Not stated | Opt-in adapter mode | No | No | | Heat pausing | No | Not stated | No | No | No | No | From each developer’s release notes and pages: AlDente 1.39, BatFi’s site (its heat pause works only on Macs that have never had macOS 27), batt 0.9.0. “Not stated” means the developer’s macOS 27 notes don’t say. ## What you lose on macOS 27 - **Draining with the charger plugged in.** While macOS’s limit is in charge, the firmware ignores the switch that cut the charger. (batt’s opt-in adapter mode cuts wall power another way.) - **Pausing for heat,** in the apps that used the same switches. - **Exact control.** macOS decides when charging stops and starts again, and still charges to 100% now and then to check the battery. What keeps working: the limit itself, charging to 100% when you ask, and everything an app does on top, like schedules, notifications and health records. ## Chargeberry on macOS 27 Since version 1.1, Chargeberry notices when the charging controls are locked and sets macOS’s own Charge Limit instead. Your limit, Charge to 100%, Full by and its schedules, shortcuts, alerts, the health history and Battery Wrapped all keep working. Limits below 80%, drain down, calibration and heat pausing are turned off there, and the app says so. If you had set macOS’s Charge Limit yourself, Chargeberry gives it back as it was when you turn its limit off or uninstall it. **Honest note:** if you need a limit below 80% on macOS 27 right now, batt (free), BatFi or AlDente can do it and Chargeberry can’t. > According to Chargeberry’s 1.1 release notes, on Macs where macOS 27 locks the charging controls, Chargeberry sets macOS’s own charge limit for you, from 80% to 100%, along with Charge to 100%, Full by and its schedules. — Chargeberry 1.1, released October 28, 2026: [the changelog](https://chargeberry.app/changelog/#v1-1). On those Macs, macOS decides exactly when charging stops and starts. ## Setting up a limit on macOS 27 1. ### Update your app first Make sure your limiter supports macOS 27 (Chargeberry 1.1, AlDente 1.39, batt 0.9.0, BatFi 4 or later). 2. ### Remove old helpers If you’ve switched apps, remove the old app’s helper too, not just the app. Leftovers can get in the way of the new limit. 3. ### Turn off Optimized Battery Charging System Settings › Battery › ⓘ next to Charging. One thing deciding when to charge is enough. 4. ### Choose your limit In your app, or in System Settings’ Charge Limit if you don’t use one. 80% suits most people. ## Questions about macOS 27 and charge limits **Does macOS 27 have a charge limit?** Yes. macOS’s own Charge Limit, added in macOS Tahoe 26.4, is in macOS 27 too: System Settings › Battery › ⓘ next to Charging, from 80% to 100%, on Macs with Apple silicon. **Why did AlDente stop working on macOS 27?** Versions made before macOS 27 used SMC charging keys that macOS 27 firmware now reserves for Apple’s own processes. AlDente 1.39 rebuilt its charge control for macOS 27, so updating fixes it. **Can I still drain the battery while plugged in on macOS 27?** Mostly not. With macOS’s own charge limit in charge, the firmware ignores the switch apps used to cut the charger. batt offers an opt-in adapter mode that cuts wall power instead, which works only while batt is awake. Chargeberry turns drain off on macOS 27. **Is it safe to use a charge limiter on macOS 27?** Yes, with an app updated for it. They now use macOS’s own charge-limit service, the same one System Settings uses, and macOS enforces the limit itself. **Will Chargeberry support limits below 80% on macOS 27?** Not today: on macOS 27, Chargeberry 1.1.2 offers the limits macOS lists, 80% to 100%. Other apps now set lower targets through the same service; if Chargeberry adds that, its changelog will say so. ## Sources - [batt issue #152: macOS 27 SMC charge keys gated](https://github.com/charlie0129/batt/issues/152) - [batt pull request #154: adapter mode on macOS 27 firmware](https://github.com/charlie0129/batt/pull/154) - [batt 0.9.0 release notes (macOS 27)](https://github.com/charlie0129/batt/releases/tag/v0.9.0) - [batt compatibility](https://github.com/charlie0129/batt/blob/master/docs/compatibility.md) - [AlDente 1.39 release (macOS 27)](https://github.com/AppHouseKitchen/AlDente-Battery_Care_and_Monitoring/discussions/1814) - [BatFi](https://micropixels.software/batfi) - [Report: charge limit apps on macOS 27 (macos-tahoe.com)](https://macos-tahoe.com/blog/macos-27-battery-charge-limit-apps-broken-aldente-batt-charging-to-100-fix-2026/) - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 --- # Is it bad to keep a MacBook plugged in all the time? > It’s safe, and a Mac can’t overcharge. But a battery held at 100% and kept warm ages faster, so an 80% limit and a cool Mac help it last longer. URL: https://chargeberry.app/guides/keep-macbook-plugged-in/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide # Is it bad to keep a MacBook plugged in all the time? It’s safe, and a Mac can’t overcharge. But a battery held at 100% and kept warm ages faster, so an 80% limit and a cool Mac help it last longer. Short answer: no, it isn’t dangerous, and you don’t need to unplug it every evening. But “always plugged in” does change how fast the battery ages, and a couple of small changes make a real difference over the years. ## What actually wears a MacBook battery A lithium-ion battery loses capacity as it chemically ages. Apple puts it this way: a battery’s chemical age results from a combination of factors, including its temperature history and its charging pattern. Two things speed that up the most: - **Sitting at a high charge.** A full battery is under more strain than one at 50–80%, and the longer it stays full, the more it adds up. Battery University’s research summary makes the same point: lower charge levels and partial charges are gentler. - **Heat.** Warm batteries age faster, and heat plus a full charge is the worst combination. A MacBook that lives on its charger gets both: it charges to 100% early in the day and stays there for hours, warm from working. That’s the problem a charge limit solves. > According to Chargeberry’s measured charge rates on a MacBook Air (M1, 2020), a MacBook plugged in at 60% at 9:00 AM is full by 10:19 AM and then sits at 100% for 7 hours 41 minutes until 6:00 PM. With an 80% limit it reaches 80% at 9:24 AM and never sits full. — Worked out from Chargeberry’s charge-rate record (Chargeberry’s own charge-rate record on a MacBook Air (M1, 2020) with a 30 W USB-C charger: 104 one-percent steps, as recorded on October 28, 2026.): 1.2 minutes per percent below 80%, 2.5 from 80 to 89% and 3.0 from 90 to 99%. A different Mac or charger changes the times. ## Five habits that keep the battery healthy 1. **Hold it around 80% when you’re plugged in.** macOS 26.4 and later has a Charge Limit in System Settings › Battery; an app like [Chargeberry](https://chargeberry.app/) works on macOS 14 and later. [How to set it up](https://chargeberry.app/guides/limit-macbook-charging-to-80/) 2. **Go lower if it never leaves the desk.** 60% is plenty for a desk Mac. [Limits below 80%](https://chargeberry.app/guides/mac-charge-limit-below-80/) 3. **Keep it cool.** Hard, flat surfaces; nothing over the vents or keyboard. Let it pause charging when hot, if your app can. 4. **Charge to 100% when you need the range, not out of habit.** Do it just before you leave, so it doesn’t sit full for hours. A “full by” time does this for you. 5. **Don’t run it to 0%.** Shallow use is gentler than deep discharges. Calibrate now and then only if the percentage looks off. **Check how your battery is doing:** System Settings › Battery › ⓘ next to Battery Health shows its Maximum Capacity and Condition. Or try the [battery health calculator](https://chargeberry.app/battery-health-calculator/) with the numbers from System Information. ## Three myths - **“You should drain it fully every month.”** That was advice for old battery types. Today it just uses up a cycle; one full cycle now and then only helps the percentage reading. - **“Leaving it plugged in will overcharge it.”** It can’t; charging stops at full. The wear comes from sitting full, not from more charge going in. - **“A limit will hurt the battery because it never gets used.”** Resting at a moderate level is what batteries like. Use it on battery whenever you like. ## Questions about keeping a MacBook plugged in **Can a MacBook overcharge if I leave it plugged in?** No. The Mac stops charging when the battery is full and runs from the charger. The issue isn’t overcharging, it’s the battery sitting at 100%, which wears it a little faster than a lower level. **Should I let my MacBook battery drain to 0% sometimes?** No. Deep discharges are harder on lithium-ion batteries than shallow ones. Use it normally; there’s no need to run it flat. If the percentage seems off, one full cycle now and then (calibration) is enough. **Does heat really matter that much?** Yes. Heat speeds up a battery’s chemical aging, and it adds to the wear from a high charge. A warm Mac at 100% on a sofa cushion is the worst case. Keep vents clear, and if your app can pause charging when the battery is hot, turn it on. **Is it better to unplug my MacBook overnight?** It doesn’t need to be unplugged. With a charge limit, staying plugged in overnight is fine: the battery rests at the limit and the charger runs the Mac. **How long should a MacBook battery last?** Apple says MacBook batteries are designed to keep up to 80% of their original capacity at their maximum cycle count, which is 1,000 cycles for modern MacBooks. How many years that takes depends on how you use and charge it. **Do I need an app, or is Optimized Battery Charging enough?** Optimized Battery Charging helps if your routine is regular: it holds at 80% when it expects you to stay plugged in. For a fixed limit, use macOS’s Charge Limit on macOS 26.4 or later, or an app like Chargeberry for lower limits, heat pausing and schedules. ## Sources - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [Apple: Determine battery cycle count for Mac laptops](https://support.apple.com/en-us/102888), checked November 6, 2026 - [Battery University: How to prolong lithium-based batteries (BU-808)](https://www.batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) --- # Why does my Mac still charge to 100%? > Usually because macOS charges to 100% now and then to keep its battery estimates accurate. Shutdowns, Optimized Charging and app conflicts come next. URL: https://chargeberry.app/guides/why-does-my-mac-charge-to-100/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Guide # Why does my Mac still charge to 100%? Usually because macOS charges to 100% now and then to keep its battery estimates accurate. Shutdowns, Optimized Charging and app conflicts come next. You set a limit, or turned on Optimized Battery Charging, and then found your MacBook sitting at 100%. It’s one of the most common battery questions, and there’s almost always a simple reason. Here are the eight we see, in the order to check them. ## 1\. macOS is checking the battery This is the one most people don’t know about. Apple says that whether you use Optimized Battery Charging or Charge Limit, **your Mac will occasionally charge to 100% to maintain accurate battery state-of-charge estimates**. The battery’s gauge needs to see a full charge now and then to keep its percentage honest. It’s normal and nothing to fix; afterwards the Mac goes back to your limit. ## 2\. Optimized Battery Charging decided you’ll need it Optimized Battery Charging isn’t a limit. It learns your routine and holds at 80% only when it predicts you’ll stay plugged in, then finishes to 100% before it expects you to unplug. If your days vary, it often charges fully. For a fixed number, use Charge Limit on macOS 26.4 or later, or a charge limiter app. ## 3\. The Mac was shut down while plugged in Apps can’t run while a Mac is off, so an app’s limit can’t hold then: a Mac left plugged in while shut down charges to 100%. Sleep instead of shutting down, or unplug before you shut down. With Chargeberry, the limit is back as soon as the Mac starts again. ## 4\. Someone chose a full charge “Charge to Full Now” in macOS’s battery menu, or Charge to 100% Now, a Full by plan or the Travel preset in Chargeberry, all charge to 100% on purpose. In Chargeberry, Charge to 100% ends two minutes after you unplug and Full by ends at its time, so the limit comes back without you doing anything. ## 5\. The app isn’t actually in control Charge limiter apps need a background helper that macOS asks you to approve once, in System Settings › General › Login Items & Extensions. If it was never approved, or was turned off, the app can show your limit without being able to hold it. Chargeberry says so in its menu and links straight to the setting. ## 6\. Two things are controlling charging Two charge limiter apps, or an app plus Optimized Battery Charging or macOS’s Charge Limit, undo each other’s work: one stops charging, the other starts it. Keep one. Chargeberry warns when it finds AlDente, BatFi, batt or Battery Toolkit installed, or Optimized Battery Charging or macOS’s Charge Limit turned on. **Moved from another app?** Remove its helper, not just the app. On macOS 27, users have reported leftover helpers from old battery apps interfering with the new limits. ## 7\. macOS changed under the app macOS 27 locked the charging controls that every limiter used, and apps that hadn’t updated stopped holding their limits, so Macs charged to 100%. A report on macos-tahoe.com lists AlDente, batt and Battery Toolkit among those affected before their updates. Update your app (AlDente 1.39, batt 0.9.0 and Chargeberry 1.1 support macOS 27). [What changed in macOS 27](https://chargeberry.app/guides/macos-27-battery-charge-limit/) ## 8\. A calibration is running A calibration, whether you started it in Chargeberry or another app, charges to 100% first on purpose, then runs the battery down. In Chargeberry the menu shows each step, such as “Calibrating, step 2 of 4: holding at 100%”, and you can stop it at any time. [How calibration works](https://chargeberry.app/guides/calibrate-macbook-battery/) > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second. That fail-safe is deliberate: if the app or its helper ever stops, the Mac charges normally rather than not at all. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. Last verified October 28, 2026. ## A quick checklist 1. Click the battery icon: does it say “Charging On Hold” or “Charged to \[%\] Limit”? 2. Is only one thing controlling charging (one app, Optimized Charging off)? 3. Is the app’s helper approved in Login Items & Extensions? 4. Was the Mac shut down, or did someone choose a full charge? 5. Is your app up to date for your macOS version? ## Questions about charging to 100% **Is it a problem if my Mac charges to 100% once in a while?** No. An occasional full charge is normal and doesn’t undo the benefit of a limit. What wears a battery is sitting at 100% day after day, especially while warm. macOS even does it on purpose now and then to keep its percentage accurate. **How often does macOS charge to 100% for calibration?** Apple doesn’t say how often. It says only that with Optimized Battery Charging or Charge Limit, your Mac will occasionally charge to 100% to maintain accurate battery state-of-charge estimates. **How do I see why my Mac is charging?** Click the battery icon in the menu bar: macOS shows “Charging On Hold” when Optimized Battery Charging is waiting and “Charged to \[%\] Limit” at its Charge Limit. Chargeberry’s menu says in plain words what it’s doing, for example “Held at 80% · running on the charger”. **My limit stopped working after a macOS update. Why?** macOS 27 locked the low-level charging controls that battery apps used, so older versions of those apps stopped holding their limits. Update the app; on macOS 27, Chargeberry 1.1 or later sets macOS’s own charge limit instead. **Does Chargeberry ever charge to 100% by itself?** Only when you ask: Charge to 100% Now, a Full by plan, a Travel (100%) limit, or a calibration you start. Each one ends on its own and your limit comes back. ## Sources - [Apple: About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026 - [Battery Toolkit README (charging while shut down)](https://github.com/mhaeuser/Battery-Toolkit) - [Report: charge limit apps on macOS 27 (macos-tahoe.com)](https://macos-tahoe.com/blog/macos-27-battery-charge-limit-apps-broken-aldente-batt-charging-to-100-fix-2026/) --- # MacBook battery guides > Plain answers to common MacBook battery questions: charge limits, 100% charges, macOS 27, calibration, health and keeping a Mac plugged in.

Notarized by Apple Signed with Developer ID No account, no telemetry Fails safe to normal charging Automatic updates ## Why stop at 80%? Batteries age fastest full and hot. A lithium-ion battery wears out quickest when it sits at a high charge, and faster still when it's warm. A MacBook that lives on its charger spends most of its life at 100%. **Chargeberry stops charging at your limit and lets the charger power the Mac directly**, so the battery rests at a gentler level instead of being held full all day. ### Without a limit macOS charges to 100% and keeps it there. ### With Chargeberry Charging stops at 80%. The charger runs the Mac. ## Everything a battery limit should do. Nothing it shouldn't. Chargeberry sits in your menu bar. A small helper does the charging control, so **your limit holds with the app closed, after a restart, and for every user of the Mac.** Every picture below is live. Charge limit ### Pick a limit, or switch between three. **Desk 60%** for a Mac that's always plugged in, **Daily 80%** for everyday use, **Travel 100%** before a trip. Or set your own anywhere from 50 to 100%. Charging stops at the limit and starts again 3% lower, so it isn't flicking on and off all day. You can change that gap in Settings. Heat protection ### Pauses charging when the battery is hot. Charging warms a battery, and heat is what wears it fastest. When the battery reaches **40 °C**, Chargeberry pauses charging and the Mac keeps running on the charger. It picks up again once the battery cools 2 °C, so it never flickers at the line. The temperature is yours to set, from 35 to 45 °C. Full when you need it ### Charge to 100% now, or be full by a time. Leaving early tomorrow? Set **Full by 8:00** and Chargeberry holds your limit overnight, then starts charging just in time to be full as you leave, so the battery spends minutes at 100%, not hours. It learns how fast your Mac charges and adds a safety margin. **Make it a schedule**, like Full by 8:30 on weekdays, and Chargeberry plans every morning by itself. Sleeping in? Skip a day from the menu. **Charge to 100% Now** is one click, and the limit comes back by itself when you unplug. Drain down automatically ### Back down to your limit, by itself. After a trip at 100%, a battery on the charger would sit full for days. Turn on **Drain down automatically** and the Mac runs on its battery, with the charger plugged in, down to your limit, then switches back to the charger. It only runs while you're using the Mac, never during sleep, and stopping it means it waits until you plug in again. Battery calibration ### Keeps the battery percentage honest. macOS works out the battery's capacity from full charges and low ones, and a battery held at a limit rarely sees either, so the percentage can drift. **Calibrate Now** runs one full cycle for you, with the charger plugged in the whole time, while you keep working. Progress shows step by step in the menu, Stop is one click, and Chargeberry reminds you once a month. Keyboard shortcuts ### Your battery, from the keyboard. Set your own shortcuts for **Charge to 100% now**, **turn the limit on or off**, **drain to the limit** and **open the menu**. They work from any app, and a small bubble under the menu bar says what happened. Press one again to stop. Shortcuts macOS already uses are refused, so nothing clashes. Live power flow ### See where every watt goes. Battery Details shows the charger, the Mac and the battery with an arrow for each flow and its watts, live: when the charger runs the Mac and charges the battery, when the battery rests at the limit, and when a weak charger can't keep up. The numbers come straight from the battery controller, averaged over a few seconds so they add up. Sleep ### Never charges past your limit in its sleep. A Mac can't watch its battery while it sleeps, so Chargeberry plans ahead. **Lid closed**, it keeps charging toward your limit and wakes the Mac quietly to check. **Lid open**, where a wake would light the screen, it stops charging for the night instead. Charging to the limit while you're away, it keeps the Mac from dozing off until it gets there. Battery health ### Watch your battery's health over months. Chargeberry records the battery's capacity once a day and draws the trend: how much it's wearing a year, how many cycles a month, and roughly how long until it reaches 80%, when Apple suggests service. Conflicts ### Spots what gets in the way. macOS's Optimized Battery Charging, the charge limit in macOS 26.4 and later, or another battery app can all work against your limit. Chargeberry notices and tells you, with a button straight to the right setting. If something keeps changing charging behind its back, it puts your limit back and says so. New ## Battery Wrapped. Your battery's month, made to share. Once a month, Chargeberry makes a card about your battery: its health, the hours it was kept off 100%, its hottest moment and the cycles it used, plus the mood it earned. **Everything on it is measured on your Mac.** Share it on X in one click, then ask your friends for theirs. ## And everything else. ### A menu bar icon that tells you The charge, a tick where your limit is, and a badge for charging, held on the charger, or paused for heat. ### Notifications that matter Held at your limit, fully charged, paused for heat, drained, ready for Full by, calibrated, and conflicts. Once each, never nagging. ### A low battery warning you choose Warns at the charge you pick, from 10 to 50%, with the time left, once each time you unplug, so you hear about it while there's still time to find a charger. ### Time left in the menu bar On battery, the menu bar can show the time left next to the percentage, like 2:57. Plugged in, it goes away. ### Set up in a minute A short welcome installs the helper, picks your limit and checks for conflicts, with exact steps for macOS's approval. ### Safe by design If anything holding the battery quits or crashes, normal charging comes back within a second. Low battery with the charger paused? It's restored. ### Learns your charger Measures how fast your Mac really charges, band by band, so Full by starts on time with your charger. ### Uninstalls cleanly One button puts charging back to normal and removes the helper. Delete the app and the helper restores charging and leaves. ### Settings that apply instantly The limit, where charging starts again, heat protection and its temperature, drain down, open at login. No Save button. ### A command line too `chargeberryctl` shows the battery, the helper, the health record and the usage record, for the curious. ### Private The app has no account, no analytics and no tracking. Your battery's data stays on your Mac unless you share a card yourself. ## A real Mac app, written in Swift. The app is native SwiftUI: a menu bar item, a settings window and a welcome. Charging control lives in a small helper that macOS asks you to approve once. It talks to the battery controller directly, only ever changes charging, and checks the app's signature on every connection. No Electron, no web view, nothing running in a browser. It reads the battery's sensors every few seconds and sleeps the rest of the time.

Lithium-ion batteries age fastest when they're held at a high charge and when they're warm, which is exactly what happens to a MacBook that lives on its charger. Keeping the charge around 80% and pausing charging when it's hot slows that wear down. Your battery will still age, just more slowly. [Is it bad to keep a MacBook plugged in?](https://chargeberry.app/guides/keep-macbook-plugged-in/) **Will my Mac still run on the charger?** Yes. At the limit, the battery stops taking charge and the charger powers the Mac directly. Nothing about how your Mac performs changes. **What about Optimized Battery Charging and macOS's own limit?** Optimized Battery Charging only holds at 80% some of the time, guessed from your routine, and the Charge Limit in macOS 26.4 and later goes from 80% to 100%. Chargeberry gives you any limit from 50 to 100%, heat protection, Full by and more. Running two at once makes them fight, so Chargeberry tells you if one is on and takes you to the setting. [macOS's Charge Limit vs Chargeberry](https://chargeberry.app/vs/macos-charge-limit/) **Does it work on macOS 27?** Yes. On macOS 27, Apple locked the low-level charging controls that battery apps used, so on those Macs Chargeberry sets macOS's own charge limit for you and macOS holds it, even while the Mac sleeps. Your limit, Charge to 100%, Full by and its schedules, shortcuts, alerts, health and Battery Wrapped all work. Apple's limit only goes from 80% to 100%, and it doesn't let apps run the Mac on its battery with the charger plugged in, so the 60% preset, drain down, calibration and heat pausing aren't available there. [What changed in macOS 27](https://chargeberry.app/guides/macos-27-battery-charge-limit/) **Which Macs are supported?** MacBooks with Apple silicon (M1 or newer) on macOS 14 Sonoma or later. Chargeberry checks what your Mac's firmware supports and only uses what works there. Intel Macs aren't supported; on an Intel MacBook, AlDente is the app to try. **Does it work while my Mac sleeps?** Yes. With the lid closed it keeps charging toward your limit and wakes the Mac briefly to check. With the lid open it stops charging for the sleep instead, so your screen never lights up at night. **Is there a free trial?** No. Instead, the demo at the top of this page is a working Chargeberry: it runs the same charging rules as the app, so you can see exactly what it does before you buy. Setup, licenses and more are on the [support page](https://chargeberry.app/support/). **Can I get a refund?** No refunds allowed: all sales are final (see our [refund policy](https://chargeberry.app/refund-policy/)). Chargeberry is a digital download and your license key works the moment you pay. Please try the [demo at the top](#demo) before you buy, and check the requirements: an Apple silicon MacBook on macOS 14 or later. If something isn't working on your Mac, email [adgan.business@gmail.com](mailto:adgan.business@gmail.com) and we'll help fix it.

This website counts visits with DataBull, described below. ## The app - Chargeberry has no account and sends no analytics, crash reports or usage data anywhere. - Your settings, the daily health record and the usage record behind Battery Wrapped stay on your Mac, in `/Library/Application Support/com.chargeberry.app`. - A Battery Wrapped card only leaves your Mac when you share, copy or save it yourself. - To check for updates, the app asks our update server for the latest version. That request carries the app’s version and your macOS version, like any Mac app’s update check, and nothing else. ## This website - Visits are counted with DataBull analytics: the page you’re on, the site you came from, your browser’s language and time zone, and your screen size. Like any website, its server sees your IP address, which tells it roughly which country a visit comes from. It may set a first-party cookie to recognise a returning visitor. - Analytics never receives your license key. When you buy, it receives the sale, your name and your email address, so we can see which visit led to it. - No ads, no advertising trackers, and nothing is sold. The demo and the battery health calculator run entirely in your browser. - The web host keeps standard server logs (such as IP addresses and pages requested) for security and reliability, and deletes them on its usual schedule. ## Your license When you activate Chargeberry, the app sends your license key to Gumroad to activate it, and checks once a day that it’s still valid. Keys bought earlier through Dodo Payments are checked with Dodo the same way, along with your Mac’s name. The key is saved only on your Mac. ## Buying Checkout is handled by Gumroad, which receives what you enter there (such as your email address and payment details) to process the purchase and send your license.

Here’s how, and how to fix problems. URL: https://chargeberry.app/support/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Support # Chargeberry support Setup takes about a minute: open Chargeberry, approve its helper once, paste your license key and pick a limit. Here’s how, and how to fix problems. ## Install and set up 1. ### Download and open Open Chargeberry.dmg (4.9 MB) from your purchase email or the download link, drag Chargeberry to Applications, and open it from there. 2. ### Approve the helper The welcome installs Chargeberry’s helper. macOS asks you to allow it once in System Settings › General › Login Items & Extensions; the welcome shows exactly where. 3. ### Activate your license Paste the license key from your Gumroad receipt when Chargeberry asks, or later in Settings › General › License. 4. ### Choose a limit Daily (80%) is a good start. Chargeberry checks for anything that would get in the way, like Optimized Battery Charging, and tells you. **Needs:** macOS 14 Sonoma or later on a MacBook with Apple silicon (M1 or newer). Intel Macs aren’t supported. ## Your license Your key is in the email from Gumroad. It works on up to 3 of your Macs. Lost it? Email [adgan.business@gmail.com](mailto:adgan.business@gmail.com) from the address you bought with and we’ll send it again. Chargeberry checks the license about once a day when it can; being offline never locks you out. ## On macOS 27 macOS 27 locked the charging controls Chargeberry uses on earlier versions, so there it sets macOS’s own charge limit instead. Your limit (80% to 100%), Charge to 100%, Full by and its schedules, shortcuts, alerts, health and Battery Wrapped keep working; limits below 80%, drain down, calibration and heat pausing are off there. [More about macOS 27](https://chargeberry.app/guides/macos-27-battery-charge-limit/) ## If it isn’t holding the limit - **Check the menu.** Chargeberry’s menu says what it’s doing and why, and shows a note if something needs your attention. - **Approve the helper.** If the menu says the helper isn’t allowed, turn Chargeberry on in System Settings › General › Login Items & Extensions. - **Turn off other things that control charging:** Optimized Battery Charging, macOS’s own Charge Limit (on macOS 26.4 and later, unless you’re on macOS 27), and other battery apps such as AlDente, BatFi, batt or Battery Toolkit, including their helpers. - **Expect the odd 100%.** macOS charges fully now and then to check the battery, and a Mac that’s shut down while plugged in charges to 100%. [All the reasons](https://chargeberry.app/guides/why-does-my-mac-charge-to-100/) > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second. If the app or its helper ever stops, the Mac goes back to charging normally rather than not charging at all. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. Last verified October 28, 2026. ## Uninstall Open Settings › Advanced › Uninstall Chargeberry. It restores normal charging, removes the helper and everything Chargeberry saved, frees this Mac’s place on your license where it can, and moves the app to the Trash. If you had set macOS’s Charge Limit yourself on macOS 27, it’s put back as it was. ## Contact Email [adgan.business@gmail.com](mailto:adgan.business@gmail.com). You’ll hear back from the person who makes Chargeberry. For news and quick questions, there’s also [X](https://x.com/ayeshagagan). ## Common questions **Why does Chargeberry need a helper and my approval?** Changing how a Mac charges needs system privileges, so a small helper does it, and macOS asks you to allow it once in System Settings › General › Login Items & Extensions. The helper only changes charging, only accepts requests from Chargeberry itself, and puts charging back to normal if anything goes wrong. **What happens if I quit or uninstall Chargeberry?** Quitting the app leaves your limit in place: the helper keeps it. Settings › Advanced › Uninstall Chargeberry puts charging back to normal and removes the helper and its data. If you just drag the app to the Trash, the helper notices, restores normal charging and leaves on its own. **Can I use Chargeberry on more than one Mac?** Yes. One license works on up to 3 of your Macs. Replacing a Mac? Email adgan.business@gmail.com and we’ll free up its place. **Will Chargeberry slow down my Mac or drain the battery?** No. About 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. The helper reads the battery’s sensors every few seconds and sleeps in between. **What is Battery Wrapped?** A monthly card about your battery: its health, the hours it was kept off 100%, its hottest moment and the cycles it used, with a berry mood. It’s made from what Chargeberry measured on your Mac, and nothing leaves your Mac unless you share it. **What if something isn’t working?** Email adgan.business@gmail.com and you’ll hear back from the person who built it. Saying which Mac and macOS version you have helps; Settings › Advanced shows Chargeberry’s version and what its helper is doing. --- # MacBook battery health calculator > Enter your battery’s design capacity, capacity now and cycle count to see its health, its wear per cycle and how far it is from Apple’s 80% mark. URL: https://chargeberry.app/battery-health-calculator/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Free tool # MacBook battery health calculator Enter your battery’s design capacity, capacity now and cycle count to see its health, its wear per cycle and how far it is from Apple’s 80% mark. ## How the calculator works **Health** is the capacity now divided by the design capacity. **Wear per 100 cycles** is how much capacity the battery has lost so far, spread over the cycles it has used. From that, the calculator estimates how many more cycles it may take to reach 80%, the level Apple designs MacBook batteries to keep at their maximum cycle count. It’s a straight-line estimate: real batteries don’t wear evenly, and heat and long stretches at 100% speed it up. > According to Chargeberry’s battery record, the MacBook Air (M1, 2020) it was built on holds 3,643 of its 4,382 mAh design capacity (83.1%) after 353 cycles: about 4.8% of its capacity lost per 100 cycles, with 353 of its 1,000 rated cycles used. — Measured by Chargeberry: read from the battery controller (DesignCapacity, NominalChargeCapacity and CycleCount in ioreg’s AppleSmartBattery) on November 6, 2026; System Information shows Maximum Capacity 83% and Condition Normal. One Mac’s battery; yours will differ with age, heat and how it’s charged. ## Where to find each number 1. ### Open System Information Hold the Option key, click the Apple menu and choose System Information. 2. ### Select Power In the sidebar, under Hardware, choose Power. Battery Information shows the Cycle Count, Condition and Maximum Capacity. 3. ### For the exact mAh, use Terminal Run `ioreg -rn AppleSmartBattery | grep -E "DesignCapacity|NominalChargeCapacity|CycleCount"`. DesignCapacity is the battery when new; NominalChargeCapacity is what it holds now, the figure System Settings’ Maximum Capacity is based on. (AppleRawMaxCapacity is the raw reading and usually a little lower.) **On Apple silicon,** System Information shows Maximum Capacity as a percentage rather than in mAh. You can type that straight in: set design capacity to 100 and capacity now to the percentage. ## How to slow the wear down Most of a MacBook battery’s wear comes from long stretches at 100% and from heat. Holding the charge around 80% while you’re plugged in, and pausing charging when the battery is hot, slows both. [Is it bad to keep a MacBook plugged in?](https://chargeberry.app/guides/keep-macbook-plugged-in/) explains why, and [Chargeberry](https://chargeberry.app/) does both automatically, and records your battery’s health every day so you can watch the trend. ## Questions about battery health numbers **What is a good battery health for a MacBook?** Anything above 80% is within what Apple designs for: MacBook batteries are meant to keep up to 80% of their capacity at their maximum cycle count. A battery at 90% after a few hundred cycles is doing well. **What does Maximum Capacity mean in System Settings?** How much charge the battery can hold now, compared with when it was new. 83% means a full charge holds about 83% of what it did originally, so a full charge lasts about that much less. **How many cycles does a MacBook battery last?** Apple rates modern MacBook batteries for 1,000 cycles. One cycle is using 100% of the battery’s capacity in total, which can take several days of partial use. **Why is my calculated health different from System Settings?** System Settings rounds to a whole percent and Apple may adjust its figure; the raw mAh numbers from ioreg can give a slightly different result. Both are estimates from the battery’s own gauge, and they move a little from day to day. **Can battery health go back up?** Not really. It can wobble by a percent or so as the gauge re-estimates, especially after a full charge, but lost capacity doesn’t come back. What you can do is slow the rest down, mainly by avoiding long stretches at 100% and heat. ## Sources - [Apple: Determine battery cycle count for Mac laptops](https://support.apple.com/en-us/102888), checked November 6, 2026 --- # AlDente alternative: Chargeberry vs AlDente > AlDente is the best-known Mac charge limiter, with a free tier and Intel support. Chargeberry includes everything for $5.99 once, on Apple silicon. URL: https://chargeberry.app/vs/aldente/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Comparison # AlDente alternative: Chargeberry vs AlDente AlDente is the best-known Mac charge limiter, with a free tier and Intel support. Chargeberry includes everything for $5.99 once, on Apple silicon. The short answer Pick AlDente if… you have an Intel MacBook or macOS 12–13, you only want a free charge limit, or you want Sailing Mode, MagSafe LED control or limits below 80% on macOS 27. Pick Chargeberry if… you’re on Apple silicon and want heat protection, Full by schedules, drain down, calibration and battery health in one $5.99 payment, with no subscription and nothing that stops working offline. ## Chargeberry vs AlDente at a glance Chargeberry and AlDente compared, November 6, 2026 | Feature | Chargeberry | AlDente | | --- | --- | --- | | Price | **$5.99** once, everything included | Free; Pro €11.49 a year or €23.99 lifetime | | Macs per license | Up to 3 | Up to 3 user accounts or Macs | | Charge limit | 50–100% (80–100% on macOS 27) | Yes, free (below 80% on macOS 27 with a toggle) | | Heat protection | Yes | Pro | | Charge to 100% now | Yes | Pro (Top Up) | | Full by a set time, or every weekday | Yes | Pro (Schedule) | | Drain down with the charger plugged in | By hand or automatically | Free by hand; automatic in Pro | | Battery calibration | Full cycle, monthly reminder | Pro (Calibration Mode) | | Keeps the limit through sleep | Yes | Pro (Sleep Control) | | Sailing Mode / MagSafe LED control | No | Pro | | Live power flow and daily health history | Yes | Not on its feature list | | Intel MacBooks | No | Most from 2013 | | macOS | macOS 14 Sonoma or later | macOS 12 Monterey to macOS 27 | | Offline for a month | Keeps working | Switches to the free version | AlDente facts are from [its pricing page](https://apphousekitchen.com/pricing/), [FAQ](https://apphousekitchen.com/faq/) and 1.39 release notes, checked November 6, 2026; prices are as its site showed them, in euros. “Not on its feature list” means we didn’t find it there, not that AlDente can’t show any battery readings. ## What AlDente is, and why so many people use it AlDente, by AppHouseKitchen, is the charge limiter most Mac users have heard of. It started as an open-source project (its early “Classic” versions are open source; today’s Free and Pro aren’t) and grew into a polished app with a free tier, a Pro tier and a place on Setapp. It runs on macOS 12 Monterey through macOS 27, on Apple silicon and on most Intel MacBooks back to 2013, which no other app on this page can say. The free version gives you the important part: a charge limit and a manual discharge. Pro adds a long list on top, from heat protection and Sailing Mode (a band the charge can drift in before charging resumes) to MagSafe LED control, schedules, sleep control, Low Power Mode control and Apple Shortcuts. ## Where AlDente is better - **Intel Macs and older macOS.** Most Intel MacBooks from 2013 on, and macOS 12 Monterey. Chargeberry needs Apple silicon and macOS 14. - **A free charge limit.** If a limit is all you want and you don’t want to pay anything, AlDente Free does it. - **Below 80% on macOS 27.** Since 1.39 AlDente can hold a lower limit on macOS 27 with a toggle; Chargeberry follows macOS’s own 80–100% there. - **More switches.** MagSafe LED control, Low Power Mode control, Apple Shortcuts actions and customizable menu bar icons are in AlDente Pro and not in Chargeberry. - **Years of reviews.** AlDente has a long track record and a large community. Chargeberry was first released on October 25, 2026. ## Where Chargeberry is better - **Everything for $5.99, once.** Heat protection, Charge to 100%, Full by, schedules, drain down (by hand or automatically), calibration, health history and Battery Wrapped are all in the one purchase. With AlDente, most of that is Pro. - **Full by a time, planned from your own charger.** Tell Chargeberry “full by 8:30 on weekdays” and it holds your limit overnight, then starts charging just in time, using how fast your Mac actually charged in the past. The battery spends minutes at 100%, not hours. - **Offline is fine.** Chargeberry checks its license when it can and never locks you out for being offline. AlDente Pro must reach its server at least every 30 days or it drops to the free version. - **See what the battery is doing.** A live diagram shows the watts going between the charger, the battery and the Mac, and a daily health record shows how fast the battery is wearing. - **Built to fail safe.** If anything holding the charging switches quits or crashes, normal charging comes back on its own. > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second, and the app itself used about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. Last verified November 6, 2026. ## On macOS 27 macOS 27 locked the low-level charging controls every limiter used, and both apps adapted. AlDente 1.39 rebuilt its charge control for it. Chargeberry, since 1.1, sets macOS’s own charge limit on those Macs, which macOS then holds even while the Mac sleeps. **The difference on macOS 27:** Chargeberry’s limit there runs from 80 to 100%, and its drain, calibration and heat pause aren’t available. AlDente can go below 80% with a toggle. If you’re on macOS 27 and want 60%, AlDente (or batt) is the better fit today. ## What each costs For one Mac with everything turned on: Chargeberry is **$5.99 once**. AlDente Pro is **€11.49 a year** or **€23.99 lifetime**, or part of Setapp at $9.99 a month. Both licenses cover up to three Macs. If the free features are enough for you, AlDente costs nothing, and that’s a fair reason to pick it. ## Switching from AlDente to Chargeberry 1. ### Turn AlDente off Quit AlDente and, in its settings, remove its helper (or uninstall it), so only one app controls charging. 2. ### Check macOS’s own settings Turn off Optimized Battery Charging, and on macOS 26.4 or later set macOS’s Charge Limit to 100%, in System Settings › Battery › Charging (ⓘ). Chargeberry reminds you if either is on. 3. ### Install Chargeberry Download it, drag it to Applications, open it, and approve its helper once in System Settings › General › Login Items & Extensions. The welcome walks you through it. 4. ### Pick your limit Daily 80% suits most people. Set heat protection, a Full by schedule or a low battery warning if you want them. ## Which should you pick? Start with your Mac. **On an Intel MacBook, AlDente is the answer**; Chargeberry won’t run there. If you’re on macOS 27 and need a limit below 80%, AlDente (or the free batt) also wins for now. On Apple silicon, the question is how much you want. If a limit is all you need, AlDente Free or macOS’s own Charge Limit will do. If you want the battery kept cool, full by the time you leave, calibrated now and then and tracked over months, Chargeberry does all of it for $5.99 once, with nothing behind a subscription. Try the demo above and see if it fits how you work. ## Questions about Chargeberry and AlDente **Is Chargeberry a good AlDente alternative?** Yes, on a Mac with Apple silicon and macOS 14 or later. Chargeberry includes heat protection, Charge to 100%, Full by schedules, drain down, calibration and a battery health history for one payment of $5.99. On an Intel MacBook, or for a free limiter, AlDente is the better choice. **Is AlDente free?** AlDente Free includes the charge limiter and manual discharge. Heat protection, Top Up, Sailing Mode, calibration, schedules, sleep control and the rest are in AlDente Pro, which is €11.49 a year or €23.99 lifetime (prices shown on its pricing page on November 6, 2026). **Does Chargeberry work on Intel Macs like AlDente does?** No. Chargeberry needs a MacBook with Apple silicon (M1 or newer). AlDente supports Apple silicon and most Intel MacBooks from 2013, so on an Intel Mac AlDente is the one to use. **Do AlDente Pro and Chargeberry need to go online?** AlDente Pro checks its license online at least every 30 days and switches to the free version if a Mac stays offline longer. Chargeberry checks its license about once a day when it can, but being offline never locks you out: only a refunded or disabled key does. **Which one holds a limit below 80% on macOS 27?** AlDente does, with a toggle in its Charge Settings (since version 1.39). On macOS 27 Chargeberry uses macOS’s own charge limit, which runs from 80 to 100%. On macOS 26 and earlier, Chargeberry holds any limit from 50 to 100%. **Can I run AlDente and Chargeberry at the same time?** No, keep one. Two apps controlling charging work against each other. Chargeberry spots AlDente when it’s installed and tells you; quit AlDente and remove its helper before you rely on Chargeberry’s limit. ## Sources - [AlDente pricing (free vs Pro)](https://apphousekitchen.com/pricing/), checked November 6, 2026 - [AlDente FAQ](https://apphousekitchen.com/faq/), checked November 6, 2026 - [AlDente 1.39 release (macOS 27)](https://github.com/AppHouseKitchen/AlDente-Battery_Care_and_Monitoring/discussions/1814), checked November 6, 2026 - [Chargeberry’s own facts](https://chargeberry.app/), version 1.1.2 --- # BatFi alternative: Chargeberry vs BatFi > BatFi is a $15 charge limiter with rules by time and place.

Chargeberry costs $5.99 and adds Full by planning, drain down, calibration and health. The short answer Pick BatFi if… you want rules that change the limit by place as well as time, a limit below 80% on macOS 27, a list of the apps using the most power, or one licence for more than three Macs. Pick Chargeberry if… you want to pay $5.99 instead of $15, have the Mac full by a time you choose, drain back down to the limit with the charger plugged in, calibrate the battery and watch its health over months. ## Chargeberry vs BatFi at a glance Chargeberry and BatFi compared, November 6, 2026 | Feature | Chargeberry | BatFi | | --- | --- | --- | | Price | **$5.99** once | $15 once | | Macs per license | Up to 3 | Every Mac you own | | Charge limit | 50–100% | 50–100% | | On macOS 27 | 80–100% (macOS’s own limit) | Any limit, below 80% too (BatFi 4) | | Rules by time | Full by schedules (days and a time) | Yes | | Rules by place | No | Yes | | Pause charging when hot | 35–45 °C, your choice | Above 40 °C (not after macOS 27) | | Charge to 100% now | Yes | Yes | | Full by a set time, planned from your charger | Yes | No | | Drain down with the charger plugged in | By hand or automatically | Not on its page | | Battery calibration | Full cycle, monthly reminder | Steps aside for macOS’s own | | Apps using the most energy | No | Yes | | Daily health history, Battery Wrapped | Yes | Live readings; history not on its page | | Global shortcuts | Limit, top up, drain, menu | Power modes | | macOS | macOS 14 Sonoma or later | macOS 14.8 Sonoma or later | | Source code | Closed | On GitHub (MIT) | BatFi facts are from [its page on micropixels.software](https://micropixels.software/batfi) and [its GitHub repository](https://github.com/rurza/BatFi), checked November 6, 2026. “Not on its page” means we didn’t find it listed there. ## What BatFi is BatFi, by Adam Różyński (micropixels), is a well-made menu bar charge limiter for Apple silicon Macs on macOS 14.8 or later. It holds any limit from 50 to 100%, and its standout is rules: the limit can change by time of day and by where you are, so the Mac can sit at 60% at your desk, top up before you leave and charge fully at the weekend without you touching anything. It also puts what macOS keeps buried into the menu bar: watts in and out, the apps using the most power right now, cycles, temperature and health, and power modes on a global shortcut. It costs $15, once, and one licence covers every Mac you own. Its source is on GitHub under the MIT license, and it installs with Homebrew too. ## Where BatFi is better - **Rules by place.** Change the limit when you get to the office or home. Chargeberry has nothing location-based. - **Below 80% on macOS 27.** BatFi 4 holds lower limits there; Chargeberry follows macOS’s 80–100%. - **Which apps use power.** BatFi’s menu lists the apps drawing the most energy right now. - **Every Mac you own.** One BatFi licence covers all of them; Chargeberry’s covers three. - **Open code.** Its source is public on GitHub. ## Where Chargeberry is better - **Less than half the price.** $5.99 against $15. - **Full by a time, planned from your charger.** Set “full by 8:30 on weekdays” and Chargeberry holds your limit overnight, then starts charging as late as is safe, using how fast your Mac really charged before. Charging from 0 to 79% took about 1.2 minutes per percent, 80 to 89% about 2.5 minutes, and 90 to 99% about 3.0 minutes on the MacBook Air it was built on. - **Drain back down.** After a day at 100%, Chargeberry runs the Mac on its battery with the charger still plugged in, down to your limit, then switches back. It can do it automatically while you work. - **Calibration you run.** One click runs a full cycle to keep macOS’s percentage accurate, with a reminder once a month. - **Your heat limit.** Pause charging at the temperature you choose, from 35 to 45 °C. - **Health over months.** A daily record of the battery’s capacity, the trend, and a monthly Battery Wrapped card to share. > According to Chargeberry’s charge-rate record, charging from 0 to 79% took about 1.2 minutes per percent, 80 to 89% about 2.5 minutes, and 90 to 99% about 3.0 minutes, which is why it plans a Full by start time from your Mac’s own numbers instead of a fixed guess. — Measured by Chargeberry: Chargeberry’s own charge-rate record on a MacBook Air (M1, 2020) with a 30 W USB-C charger: 104 one-percent steps, as recorded on October 28, 2026. Last verified October 28, 2026. ## On macOS 27 **Know this before you buy:** on macOS 27, BatFi holds limits below 80% and Chargeberry doesn’t. Chargeberry sets macOS’s own charge limit there (80–100%) and its drain, calibration and heat pause aren’t available. BatFi’s own heat pause also stops on Macs that have had macOS 27. If you live on macOS 27 and want 60%, choose BatFi. ## Which should you pick? Both are one-time purchases for Apple silicon, both are honest about what they do, and you won’t go wrong with either. Pick by the feature you’d use every day. **If your limit should change with where you are**, or you’re on macOS 27 and want less than 80%, BatFi is the better tool. **If you want the Mac full exactly when you leave, back down to the limit after a long top-up, a calibration now and then and a record of the battery’s health**, Chargeberry does more of that, for $5.99. ## Questions about Chargeberry and BatFi **Is Chargeberry cheaper than BatFi?** Yes. Chargeberry is $5.99 once for up to 3 Macs. BatFi is $15 once, and its licence covers every Mac you own, so with four or more Macs BatFi works out cheaper per Mac. **Can BatFi change the limit by location?** Yes. BatFi’s rules can change the limit by time and by place, for example 60% at your desk and full at the weekend. Chargeberry has presets and Full by schedules by time, but nothing based on where you are. **Which holds a limit below 80% on macOS 27, BatFi or Chargeberry?** BatFi. Its site says BatFi 4 holds any limit, below 80% too, on macOS 27. Chargeberry uses macOS’s own charge limit there, which goes from 80 to 100%. On macOS 26 and earlier Chargeberry holds anything from 50 to 100%. **Does BatFi pause charging when the battery is hot?** Yes, above 40 °C, but BatFi says this works only on Macs that have never had macOS 27 installed. Chargeberry pauses at the temperature you choose, 35 to 45 °C, on macOS 14 through 26. **Is BatFi open source?** Its source code is on GitHub under the MIT license, and the app is sold from micropixels.software for $15. Chargeberry is not open source. **Which has the better battery readings?** Both show more than macOS does. BatFi lists the apps using the most energy and shows watts in and out, cycles, temperature and health. Chargeberry draws a live power diagram, keeps a daily health history with a trend, and makes a monthly Battery Wrapped card. ## Sources - [BatFi](https://micropixels.software/batfi), checked November 6, 2026 - [BatFi on GitHub (MIT license)](https://github.com/rurza/BatFi), checked November 6, 2026 - [Chargeberry’s own facts](https://chargeberry.app/), version 1.1.2 --- # Chargeberry vs batt: a Mac app or an open-source CLI? > batt is a free, open-source charge limiter you mostly drive from the Terminal.

The short answer Pick batt if… you’re happy in the Terminal, want free and open-source software, want a limit below 80% on macOS 27, or want MagSafe LED control. Pick Chargeberry if… you want a Mac app you set up with a few clicks (notarized, no Terminal), plus heat pausing, Full by schedules, drain down, calibration and battery health, for $5.99 once. ## Chargeberry vs batt at a glance Chargeberry and batt compared, November 6, 2026 | Feature | Chargeberry | batt | | --- | --- | --- | | Price | **$5.99** once | Free | | Source code | Closed | Open (GPL-2.0) | | How you use it | Menu bar app and Settings | Terminal, plus a small menu bar app | | Install | Notarized DMG, approve once | Homebrew, or an un-notarized app | | Latest release | 1.1.2 (November 1, 2026) | 0.9.0 (November 5, 2026) | | Charge limit | 50–100% | Yes | | On macOS 27 | 80–100% (macOS’s own limit) | 10–99% (macOS’s own limit, upper only) | | Charge to the limit or 100% once | Yes | Yes | | Turn the charger off while plugged in | Drain to your limit, by hand or automatically | Yes (not on macOS 27 native mode) | | Heat pausing | Yes | No | | Full by a time, or every weekday | Yes | No | | Battery calibration | Full cycle, monthly reminder | Experimental auto-calibration | | MagSafe LED control | No | Yes | | Power diagram, health history, alerts | Yes | No | batt facts are from [its README](https://github.com/charlie0129/batt), [its 0.9.0 release notes](https://github.com/charlie0129/batt/releases/tag/v0.9.0) and its compatibility page, checked November 6, 2026. ## What batt is batt, by Charlie Chiang, is a free, open-source tool that limits charging on Apple silicon MacBooks. It keeps things simple on purpose: set an upper limit (with a lower bound where the Mac supports it), charge to the limit or to 100% once, and for power users, control the MagSafe LED, cut wall power while plugged in and try its experimental auto-calibration. It runs as a daemon you install with Homebrew, with a small menu bar app on top. It’s actively maintained. Version 0.9.0 (November 5, 2026) added macOS 27 support by falling back to macOS’s own charge limit, which it sets anywhere from 10 to 99%, plus an opt-in adapter mode. Its own README also says, fairly, that if macOS’s built-in 80–100% range meets your needs, you may not need batt at all. ## Where batt is better - **Free and open source.** Read it, build it, change it. - **Below 80% on macOS 27.** batt sets 10–99% there; Chargeberry follows macOS’s 80–100%. - **Scriptable.** Everything is a command, so it fits into your own scripts and dotfiles. - **MagSafe LED control,** which Chargeberry doesn’t offer. ## Where Chargeberry is better - **Set up in a minute, no Terminal.** A notarized app, a welcome that installs the helper and checks for conflicts, and settings that apply instantly. - **More of the job.** Heat pausing at the temperature you choose, Full by a time or every weekday, automatic drain down, calibration with a reminder, notifications and a low battery warning. - **See the battery.** A live power diagram (charger, battery and Mac, in watts), a daily health history with a trend, and a monthly Battery Wrapped card. - **Support from a person.** Email the developer directly. > According to Chargeberry’s own measurements, the app uses about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. — Measured by Chargeberry: A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. Last verified November 6, 2026. ## On macOS 27 **Be clear about this:** on macOS 27 batt is ahead. It sets limits from 10 to 99% through macOS’s own charge limit, while Chargeberry offers 80–100% there and turns off its drain, calibration and heat pause. Both rely on the same mechanism Apple left open, and macOS may still charge to 100% now and then to check the battery. ## Which should you pick? **If you live in the Terminal, want free software, or need less than 80% on macOS 27, use batt.** It’s a solid, honest tool and it costs nothing. **If you want a Mac app that you never have to think about**, that keeps the battery cool, has it full by the time you leave and tells you how it’s ageing, Chargeberry is $5.99 once. Try the demo above to see the menu for yourself. ## Questions about Chargeberry and batt **Is batt free?** Yes. batt, by Charlie Chiang, is free and open source under the GPL-2.0 license. You can install it with Homebrew (brew install batt) or download its small menu bar app from GitHub. **Does batt work on macOS 27?** Yes, since version 0.9.0 (November 5, 2026). On macOS 27 it uses macOS’s own charge limit and, by its release notes, sets targets from 10% to 99%, with an upper limit only. It also has an opt-in adapter mode that cuts wall power to enforce upper and lower limits while it’s awake. **Why does macOS say batt’s app is damaged?** Its app isn’t notarized, so macOS quarantines it. batt’s instructions tell you to clear that in Terminal with sudo xattr -r -d com.apple.quarantine /Applications/batt.app. Chargeberry is notarized, so it opens normally. **Do I need the Terminal for Chargeberry?** No. Everything is in the menu bar menu and the Settings window, and a short welcome sets it up. There is a command line tool, chargeberryctl, for anyone who wants to read the battery or the helper from the Terminal, but you never need it. **Which one has more features?** Chargeberry: heat pausing, Full by a time or on a schedule, automatic drain down, calibration with a reminder, a live power diagram, a health history, shortcuts and alerts. batt keeps to the limit, one-time charging, MagSafe LED control, cutting wall power and an experimental auto-calibration. **Can batt and Chargeberry run together?** No. Use one. Two tools changing charging fight each other. Chargeberry spots batt when it’s installed and warns you; remove batt’s daemon before relying on Chargeberry. ## Sources - [batt on GitHub](https://github.com/charlie0129/batt), checked November 6, 2026 - [batt 0.9.0 release notes (macOS 27)](https://github.com/charlie0129/batt/releases/tag/v0.9.0), checked November 6, 2026 - [batt compatibility](https://github.com/charlie0129/batt/blob/master/docs/compatibility.md), checked November 6, 2026 - [Chargeberry’s own facts](https://chargeberry.app/), version 1.1.2 --- # Chargeberry vs Battery Toolkit: free and open source, or $5.99? > Battery Toolkit is free and open source, with upper and lower limits.

Battery Toolkit is free and open source, with upper and lower limits. Chargeberry is a notarized $5.99 app with heat pausing and macOS 27 support. The short answer Pick Battery Toolkit if… you want a free, open-source limiter you can read the code of, a separate lower limit, and you’re on macOS 26 or earlier and fine allowing an un-notarized app. Pick Chargeberry if… you want an app that opens like any other (notarized), works on macOS 27, plans the Mac’s sleep around your limit, and adds heat pausing, Full by, calibration and a health history, for $5.99 once. ## Chargeberry vs Battery Toolkit at a glance Chargeberry and Battery Toolkit compared, November 6, 2026 | Feature | Chargeberry | Battery Toolkit | | --- | --- | --- | | Price | **$5.99** once | Free | | Source code | Closed | Open (BSD-3-Clause) | | Notarized by Apple | Yes | No | | Latest release | 1.1.2 (November 1, 2026) | 1.8 (August 11, 2025) | | On macOS 27 | Yes, 80–100% (macOS’s own limit) | No release for it yet | | Upper charge limit | 50–100% | Yes | | Separate lower limit | Resume margin, 1–10% | Yes | | Turn the charger off while plugged in | Yes | Yes | | Stops draining at your limit by itself | Yes | You turn the charger back on | | When the Mac goes to sleep | Planned around the limit, lid open or closed | Kept awake while charging | | Heat pausing | Yes | No | | Full by a time, or every weekday | Yes | No | | Battery calibration | Full cycle, monthly reminder | By hand, with the adapter off | | Power diagram, health history, notifications | Yes | No | Battery Toolkit facts are from [its GitHub README and releases](https://github.com/mhaeuser/Battery-Toolkit), checked November 6, 2026. Its README describes the lower limit as the level below which charging turns back on. ## What Battery Toolkit is Battery Toolkit, by Marvin Häuser, is a free, open-source app that controls the power state of Apple silicon Macs. It does three things well: it stops charging at an upper limit, it waits until the charge falls below a lower limit before charging again, and it can switch the power adapter off without unplugging it, so you can run down the battery on purpose. A menu bar item gives you commands for a full charge, charging to the limit, stopping charging and pausing everything. It’s honest software with clear documentation, and its code is there for anyone to read. Two things are worth knowing before you install it: it isn’t notarized by Apple, so you allow it by hand in System Settings (its README puts this down to the Apple Developer Program’s fees), and its latest release is 1.8 (August 11, 2025). ## Where Battery Toolkit is better - **It’s free.** No license, no payment. - **Open source.** You can read every line, build it yourself and install it with Homebrew. - **A true lower limit.** Set exactly where charging should start again, as its own setting. - **Small and focused.** If all you want is a limit and a way to cut the charger, it has nothing extra. ## Where Chargeberry is better - **Notarized, so nothing to bypass.** Chargeberry is signed with a Developer ID and notarized by Apple; it opens without warnings. - **macOS 27.** Chargeberry works there, by setting macOS’s own charge limit. Battery Toolkit hasn’t had a release since before macOS 27. - **Sleep is planned, not just blocked.** Both keep the Mac from idle-sleeping while it charges toward the limit. When the Mac does sleep (you close the lid, say), Chargeberry plans for it: with the lid closed it keeps charging and wakes briefly to check, with the lid open it stops charging for the night, so the limit holds either way. - **Draining stops on its own.** Chargeberry cuts the charger, runs down to your limit and switches the charger back on by itself. - **Heat, schedules and health.** Pause when hot, be full by a time, calibrate monthly, and see the battery’s health over months. > According to Chargeberry’s crash-safety test, when the process holding a charging switch was killed, normal charging came back within 1 second, so a crash never leaves a Mac unable to charge. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller. Last verified October 28, 2026. ## On macOS 27 **Free on macOS 27?** If you want a free, open-source limiter on macOS 27, look at batt: version 0.9.0 (November 5, 2026) supports it. Battery Toolkit’s next release may add support too; check its GitHub page. ## Which should you pick? If you’re comfortable allowing an un-notarized app, you’re on macOS 26 or earlier, and a limit plus a lower limit is all you want, **Battery Toolkit is a good free choice**, and there’s no reason to pay. If you’d rather have an app that installs normally, keeps working on macOS 27, holds the limit through sleep and does the rest of the job too (heat, Full by, calibration and a health record), **Chargeberry is $5.99 once**. Try the demo above first. ## Questions about Chargeberry and Battery Toolkit **Is Battery Toolkit safe to use?** Its code is public on GitHub under the BSD-3-Clause license, so anyone can read it. The app isn’t notarized by Apple, which is why macOS warns that it can’t check it for malware and you have to allow it in System Settings › Privacy & Security. Chargeberry is signed with a Developer ID and notarized, so it opens like any other app. **Does Battery Toolkit work on macOS 27?** Its last release is 1.8 (August 11, 2025), from before macOS 27, and macOS 27 locked the charging controls it uses. A report on macos-tahoe.com says its limit no longer holds there. Check its GitHub page for news. Chargeberry supports macOS 27 by setting macOS’s own charge limit. **Why does my Mac stay awake with Battery Toolkit?** Its README explains that it keeps the Mac from sleeping while it charges, because it has to switch charging off itself at the limit. Chargeberry also keeps the Mac from idle-sleeping on its way to the limit, but when the Mac does go to sleep it plans ahead: with the lid closed it keeps charging and wakes briefly to check, and with the lid open it stops charging for the night. **Can Battery Toolkit run the Mac on battery with the charger plugged in?** Yes. It can turn the power adapter off without unplugging it, which you can use to drain the battery. Chargeberry does the same and also stops by itself at your limit, by hand or automatically. **What does Chargeberry add that Battery Toolkit doesn’t?** Heat pausing, Full by a time or every weekday, calibration with a monthly reminder, a live power diagram, a daily health history, notifications, a low battery warning, global shortcuts and support from the person who made it. ## Sources - [Battery Toolkit on GitHub](https://github.com/mhaeuser/Battery-Toolkit), checked November 6, 2026 - [Battery Toolkit releases](https://github.com/mhaeuser/Battery-Toolkit/releases), checked November 6, 2026 - [Report: charge limit apps on macOS 27 (macos-tahoe.com)](https://macos-tahoe.com/blog/macos-27-battery-charge-limit-apps-broken-aldente-batt-charging-to-100-fix-2026/), checked November 6, 2026 - [Chargeberry’s own facts](https://chargeberry.app/), version 1.1.2 --- # Mac battery charge limiters, compared > Chargeberry side by side with AlDente, BatFi, batt, Battery Toolkit and macOS’s own Charge Limit, including where each one is the better pick.

An app adds lower limits, heat pausing, Full by schedules, drain down and health. URL: https://chargeberry.app/vs/macos-charge-limit/ Author: Ayesha Gagan (https://chargeberry.app/about/) Published: 2026-11-06 · Updated: 2026-11-06 Comparison # macOS Charge Limit vs Chargeberry: do you still need an app? For a plain 80–100% cap, macOS’s free Charge Limit is enough. An app adds lower limits, heat pausing, Full by schedules, drain down and health. The short answer Pick macOS Charge Limit if… an 80–100% limit is all you want and you’re on macOS Tahoe 26.4 or later. It’s free, already on your Mac and needs nothing installed. Pick Chargeberry if… you want a limit below 80% (on macOS 14–26), charging paused when the battery is hot, the Mac full by a time or every weekday, drain down after a top-up, calibration, or a record of the battery’s health. $5.99 once. ## What macOS does by itself macOS now has two features for battery health, and it helps to know which is which: - **Optimized Battery Charging** (macOS 11 Big Sur and later) uses on-device learning to guess your routine. When it expects you to stay plugged in for a long time, it holds charging at 80% and finishes to 100% before it thinks you’ll unplug. The menu says “Charging On Hold”. You can’t choose the level or the time. - **Charge Limit** (macOS Tahoe 26.4 and later, Apple silicon) sets a fixed maximum between 80% and 100%. The Mac charges to within a few percent of it, stops, and starts again if the charge drops more than 5% on power. “Charge to Full Now” in the battery menu overrides it once. Apple adds one important line for both: your Mac will still charge to 100% now and then, to keep its estimate of the battery’s charge accurate. ## macOS Charge Limit vs Chargeberry at a glance macOS’s Charge Limit and Chargeberry compared, November 6, 2026 | Feature | macOS | Chargeberry | | --- | --- | --- | | Price | Free, built in | **$5.99** once | | Needs | macOS 26.4, Apple silicon | macOS 14+, Apple silicon | | Limit | 80–100% | 50–100% (80–100% on macOS 27) | | Where charging starts again | After a 5% drop on power | You choose, 1–10% below | | Charge to 100% once | Charge to Full Now | Charge to 100% Now, or a shortcut | | Full by a set time, or every weekday | Optimized Charging guesses | Yes | | Pause charging when hot | Not described by Apple | 35–45 °C (macOS 14–26) | | Drain down to the limit while plugged in | No | On macOS 14–26 | | Calibration you run, with a reminder | Automatic 100% now and then | On macOS 14–26 | | Live power diagram and health history | No | Yes | | Warns about other apps and settings | No | Yes | macOS facts are from Apple’s support page [About Optimized Battery Charging and Charge Limit on Mac](https://support.apple.com/en-us/102338), checked November 6, 2026. ## When macOS’s own limit is enough If you’re on macOS Tahoe 26.4 or later and what you want is “don’t sit at 100% all day”, set Charge Limit to 80% and you’re done. It’s free, it’s Apple’s, macOS enforces it itself, and there’s nothing to install or approve. Plenty of people need nothing more, and we’d rather you knew that. **On macOS 26.4 or later:** System Settings › Battery › ⓘ next to Charging › Charge Limit. Set 80%, and turn Optimized Battery Charging off so the two don’t overlap. ## What a charge limiter app adds - **Lower limits.** 60% for a Mac that lives on a desk. macOS stops at 80%. (Chargeberry holds 50–100% on macOS 14–26.) - **Heat.** Charging is what warms a battery most, and heat is what wears it fastest. Chargeberry pauses charging at the temperature you choose. - **Full when you need it, on your schedule.** Optimized Battery Charging guesses when you’ll leave; Chargeberry’s Full by lets you say it, once or every weekday, and starts charging just in time from your charger’s measured speed. - **Back down after a top-up.** After a trip at 100%, Chargeberry runs the Mac on its battery with the charger plugged in, down to your limit, instead of letting it sit full for days. - **Calibration on your terms,** with a reminder once a month. - **Knowing what’s going on.** A live power diagram, a daily health history, notifications and a warning when something else is changing charging. > According to Chargeberry’s own measurements, the app uses about 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. — Measured by Chargeberry: A development build of Chargeberry 1.1.2 (the same code as the release, without its compiler optimizations) on a MacBook Air (M1, 2020) with macOS 15.7.4, sampled with top every 5 seconds for 10 minutes (120 samples), the helper for 1 minute, and memory read with footprint, on November 6, 2026. Your numbers will vary with your Mac. Last verified November 6, 2026. ## On macOS 27 macOS 27 locked the low-level charging controls that apps like Chargeberry used, leaving macOS’s own Charge Limit as the way in. Since version 1.1, Chargeberry sets that limit for you on macOS 27, so its menu, Full by schedules, shortcuts, alerts and health history keep working. The limit itself is then macOS’s: 80 to 100%, and Chargeberry’s drain, calibration and heat pause are off there.
