macOS 26.4 adds three new battery features on Mac, here’s how to use them

macOS 26.4 is the latest Mac software update, and alongside new emoji and a Compact Tab Bar option in Safari, the new release also adds three battery-related features. Here’s how to use them.

#1: Charge Limit

Batteries degrade over time. That’s why in recent years, Apple introduced a ‘Charge Limit’ feature for iPhone that lets you set a maximum limit below 100%, which might help extend the battery’s lifespan.

With macOS 26.4, Charge Limit has come to the Mac too.

You’ll find Charge Limit by opening System Settings ⇾ Battery then clicking the ‘i’ symbol next to ‘Charging.’

Per Apple’s support document:

Use Charge Limit to set a limit on what your Mac considers a full charge. Your Mac will charge to within a few percentage points of the charge limit, then stop charging and show “Charged to [%] Limit” in the battery status menu. If the battery charge level drops more than 5% while connected to power, charging resumes, again charging to within a few percentage points of the limit.

Apple lets you set your MacBook’s maximum charge to anywhere from 80% to 100%. Though it’s hard to know how big a difference Charge Limit will make in a Mac battery’s lifespan, the idea is that a lower charge limit makes for a healthier battery over time.

#2: ‘Slow Charger’ indicator

Another new macOS 26.4 feature you’ll find inside System Settings ⇾ Battery is the ‘Slow Charger’ indicator.
