Mac battery management app with a charge limit

For Mac battery management without an extra app, macOS Tahoe 26.4 or later on Apple silicon has a Charge Limit: open System Settings › Battery, click the Info button next to Charging and choose 80% to 100%. Battery Charge Limit also goes down to 50%, pauses charging while the Mac sleeps and works from macOS 14.2 Sonoma.

What Battery Charge Limit does

The problem
Plugged in all day, a MacBook sits at 100%, and a lithium-ion battery kept full wears out faster. Before macOS Tahoe 26.4 there's no fixed limit, only Optimized Battery Charging, which decides for itself when to hold back at 80%. Tahoe's Charge Limit starts at 80%.
With Battery Charge Limit
Charging stops at the level you choose, such as 80% or 60%, and stays there while you're plugged in. Your Mac runs on the charger's power, and the battery rests.
  • Choose your limit
    Stop charging at 50, 60, 70, 75, 80, 85, 90 or 95%, or pick 100% for no limit. Charging starts again when the battery drops 3 percent below it.
  • Full when you need it
    Going on a trip? Click Charge to 100% This Once, and the limit comes back by itself once the battery is full or you unplug.
  • Works around the clock
    The limit keeps working while MrFixable is closed and after a restart, and charging pauses while your Mac sleeps, so the battery can't creep up to 100% overnight.

Good to know

  • On macOS Tahoe 26.4 or later with Apple silicon, the built-in Charge Limit may be all you need: it needs no helper, but its lowest setting is 80%.

  • Needs a small helper that you approve once in System Settings › General › Login Items & Extensions, because only a helper with administrator rights can turn charging off. MrFixable shows you where.

  • For MacBooks. If your Mac doesn't let apps control charging, MrFixable tells you.

  • Switch it off and your Mac charges normally again, and the helper is removed.

    Turn on Battery Charge Limit, which pauses charging every time your Mac goes to sleep. 1. Switch on Battery Charge Limit. 2. Approve the helper once. 3. Choose your limit. Otherwise a closed MacBook can charge past the limit overnight, because an app can't check the level while the Mac sleeps.

  • How do I set my MacBook battery to 80 percent?

    Set the limit to 80%, then top up once when you need to. 1. In Battery Charge Limit, click Charge to 100% This Once. 2. Your Mac charges to full. 3. The 80% limit comes back by itself once it's full or you unplug. Tahoe's own Charge Limit offers Charge to Full Now in the battery menu.
