UPDATE 2026/03: You can now set battery charge limit manually without any 3rd-party app! Just update your macOS version to Tahoe 26.4 and set the limit manually through System Settings.

I work from home, play at home, and rest at home. So naturally, I like keeping my devices plugged in because I rarely go out.

The problem? I don’t like keeping my battery at 100% all the time.

On newer iPhones, Apple gives you a manual charge limit. You can set it to 80%, 85%, 90%, 95%, or 100%. Super simple. Super useful. You’re in full control.

That means the battery inside the car key is almost depleted and needs to be replaced.

Recently I’ve got some notifications from my iPhone that some of my AirTags batteries were almost depleted.

What you need is just a new CR2032 battery and your thumbs.

Press the metallic side with two of your thumbs and rotate it counterclockwise.
