This model runs the same charging rules as the app, one minute every tenth of a second. Plug in, move the limit, or make it a hot day.
Chargeberry stops your MacBook charging at the limit you choose, 80% by default, so the charger runs the Mac and the battery rests while you work plugged in.
Lithium-ion batteries age fastest when they sit full and warm, which is exactly what happens to a MacBook that lives on a desk. Chargeberry holds the battery lower, lets the charger power the Mac directly, and pauses charging when the battery gets hot.
When you do need a full battery, it is one click away, or set for a time: “Full by 8:30 every weekday” charges as late as is safe, from its own measurements of your charger.

The limit
Stops at the limit you choose
Pick any limit from 50 to 100%, or a preset: Desk 60%, Daily 80% or Travel 100%. At the limit the charger powers the Mac and the battery rests. Charging starts again a few percent lower, so it doesn’t click on and off all day.
- The limit holds with the app closed, after a restart and for every user
- Charging resumes 3% lower by default (1–10%, your choice)
- Drain down to the limit with the charger still plugged in
Heat
Pauses when the battery gets hot
Heat ages a battery faster than anything else. Chargeberry pauses charging when the battery reaches the temperature you choose, from 35 to 45 °C, and starts again once it has cooled by 2 °C.
- 40 °C by default
- Starts again by itself once the battery has cooled
- A notification tells you when it pauses, if you want one
Full when you need it
Full by 8:30, every weekday
Charge to 100% Now tops up immediately and the limit comes back when you unplug. Full by holds the limit overnight, then starts charging as late as is safe so the battery is full right when you leave.
- Schedules for days of the week, with Skip in the menu
- Charging times learned from your own charger
- A low battery warning at the level you pick, and time left in the menu bar
Battery health
See how your battery is really doing
Chargeberry keeps a daily record of your battery’s health and shows the trend, along with live power flow between the charger, the battery and the Mac, in watts. Once a month a Battery Wrapped card sums it up.
- Monthly calibration with one click, to keep macOS’s percentage honest
- Spots Optimized Battery Charging and other battery apps that could fight it
- A command line tool, chargeberryctl, for scripts
Safety first
Built so your Mac always charges again
If anything holding the charging switches quits or crashes, normal charging comes back. Deleting the app makes its helper restore normal charging and leave. And the charger is only ever paused while the Mac is fully awake.
- A small helper, approved once in System Settings, talks to the battery controller
- On macOS 27 it sets macOS’s own charge limit, 80 to 100%
- Signed with a Developer ID and notarized by Apple

Questions
Getting started
Which Macs does Chargeberry work on?
MacBooks with Apple silicon (M1 or newer) running macOS 14 Sonoma or later. Intel Macs are not supported.
Why does Chargeberry need a helper?
Only a background helper can talk to the battery controller and keep your limit while the app is closed, after a restart and for every user. You approve it once in System Settings › General › Login Items & Extensions.
How many Macs can I use my Chargeberry license on?
Up to 3 of your own Macs. If you replace one, email adgan.business@gmail.com and its place is freed.
Using Chargeberry
What limit should I set for my MacBook?
80% is a good everyday limit and the default. If your Mac almost never leaves the desk, Desk (60%) keeps the battery even calmer; before a trip, Travel (100%) or Charge to 100% Now.
What happens if Chargeberry crashes or I delete it?
Normal charging comes back. In testing it came back within 1 second when the process holding a charging switch was killed, and deleting the app makes the helper restore charging and remove itself.
Does Chargeberry work on macOS 27?
Yes, with a smaller range. Apple locked the charging controls in macOS 27, so there Chargeberry sets macOS’s own charge limit (80 to 100%). Limits below 80%, drain down, calibration and heat pausing are not available on macOS 27.
Compared with macOS
macOS has a charge limit now. Do I still need Chargeberry?
For a simple 80% cap, macOS Tahoe 26.4’s own Charge Limit may be enough. Chargeberry adds limits below 80% (before macOS 27), heat pausing, Full by schedules, drain down, calibration and a health history.
Does Chargeberry collect any battery data?
No. Battery data stays on your Mac. The app goes online only to check your license with Gumroad and to check for updates.
