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.
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.

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.
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.
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. If that’s all you need on macOS 27, macOS’s setting alone does it for free.

A working model of Chargeberry, not a video, running the same charging rules as the app. Plug the charger in and out, change the limit, turn up the heat, try Charge to 100% and Full by. Time runs fast here: two minutes every second, and faster with S.
So, do you need an app?
No, if you’re on macOS 26.4 or later and a fixed 80–100% limit covers it. Use the setting.
Yes, if you want a lower limit, a heat pause, the Mac full at a time you choose, a way back down after a top-up, or a record of how your battery is ageing. That’s what Chargeberry is for, at $5.99 once. Try the demo above to see the difference.
Questions about macOS’s charge limit
Does macOS have a built-in battery charge limit?
Yes, since macOS Tahoe 26.4 on Macs with Apple silicon. In System Settings › Battery, click the ⓘ next to Charging and choose a Charge Limit between 80% and 100%. The menu then shows “Charged to [%] Limit”.
What’s the difference between Optimized Battery Charging and Charge Limit?
Optimized Battery Charging (macOS 11 and later) learns your routine and delays charging past 80% when it predicts you’ll stay plugged in, aiming to be full when you need it. Charge Limit sets a fixed maximum you choose. Optimized Battery Charging decides for you; Charge Limit doesn’t change.
Can macOS limit charging below 80%?
No. macOS’s own Charge Limit goes from 80 to 100%. For less, such as 60% on a Mac that never leaves the desk, you need an app; Chargeberry holds 50–100% on macOS 26 and earlier.
Should I turn Optimized Battery Charging off when using Chargeberry?
Yes. Two things deciding when to charge work against each other. Chargeberry notices when Optimized Battery Charging or macOS’s Charge Limit is on and takes you to the setting. On macOS 27, Chargeberry sets macOS’s Charge Limit itself.
Does macOS’s Charge Limit pause charging when the battery is hot?
Apple doesn’t describe a heat pause for Charge Limit. Chargeberry pauses charging when the battery reaches the temperature you choose (35–45 °C) on macOS 14 through 26.
Is Chargeberry worth it if I’m on macOS 27?
Only if you want what it adds on top: Full by a time or on a schedule, Charge to 100% with a shortcut, alerts, the power diagram, health history and Battery Wrapped. On macOS 27 its limit is macOS’s own (80–100%), and drain, calibration and heat pausing aren’t available there.
