Is your MacBook battery stuck at 80% even with the charger plugged in? Apple̵
Why isn’t my Mac fully charging?
In June 2020, Apple’s macOS Catalina 10.15.5 update introduced a new Battery Health Management feature for the Mac, inspired by the optimized battery charging feature on the iPhone, but implemented a little differently.
Apple introduced the new feature because it’s not good for a lithium-ion battery to charge to 100% and always stay at 100%. If you’re stuck at 80%, that means the new power-saving feature studied your usage pattern, charged your battery only to 80%, and then waited. This small adjustment helps improve the battery aging process.
With the release of macOS Big Sur, Apple rebranded this feature as Optimize Battery Charging, and this feature is enabled by default when you buy a new Apple silicone-based MacBook.
If you don’t like this feature and want your Mac to charge 100% all the time, or just occasionally (if you’re in a hurry to get out and about), you have two options.
Quickly force MacBook to fully charge from the menu bar
The fastest way to force your Mac to charge to 100% is to use the battery option in the menu bar itself.
Click on the battery icon in the top right corner of your screen and choose the option “Charge to full now”. If you don’t see it, hold down the Option key while clicking the battery icon in the menu bar.
The MacBook will now begin charging and the battery menu will display an estimated time until it is fully charged.
Temporarily or permanently disable optimized battery charging
If you want to disable optimized battery charging temporarily or permanently, it’s pretty easy to do. If you’re running macOS Catalina on an Intel-based Mac, see our Battery Health Management guide for steps to disable the feature.

If you are using an Apple Silicon MacBook or an Intel MacBook with macOS Big Sur, you can disable the Optimal Battery Charge feature for a day or permanently.
To get started, click the Apple icon in the top left corner of the screen and choose System Preferences.
In System Preferences, go to the “Battery” section.
Click on ‘Battery’ in the sidebar, then uncheck the ‘Optimized battery charging’ option.
To disable the feature for today only, click “Disable until tomorrow.” To disable it completely, select ‘Disable’.
The Optimal Battery Charging feature is now disabled. Your MacBook will be charged to 100%.
You can now click the red “Close” button in the top left corner to safely exit System Preferences.
If you ever change your mind and want to re-enable Apple’s automatic battery management, go back to System Preferences > Battery, select “Battery” in the sidebar, and check the box next to “Optimized battery charging.” Good luck!
