Is your MacBook’s battery stuck at 80% even with the charger attached? Apple’s battery-saving “Optimized Battery Charging” feature is to blame. Here’s how to charge your MacBook fully.
In June of 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 bit differently.
Apple introduced the new feature because it’s not good for a lithium-ion battery to be charged to 100% and to stay at 100% all the time. If you’re stuck at 80%, that means that the new energy-saving feature studied your usage pattern, only charged your battery up to 80%, and then waited. This little tweak helps improve the battery aging process.
