Optimized Battery Charging
The battery is arguably the most important part of any MacBook. Sadly, all batteries age and they won’t hold as much power as they used to.
Fortunately, Big Sur brings a new feature that helps your battery last longer. This new feature is called Optimized Battery Charging, and it’s meant to help reduce the wear on your battery.
When Optimized Battery Charging is on, it’ll start learning your daily charging routines. That way, when your MacBook predicts it’s going to be plugged in for a very long period of time, it’ll turn Optimized Battery Charging on so it can wait to finish charging past the 80% mark until you need to start using your battery.
This is a great feature if you’re always working or you have to plug your MacBook in constantly. The best part is that it’s really easy to use. By default, Optimized Battery Charging should be on, but if you want to turn it on for yourself or turn it off, do this:
- On the top menu bar, click on the Apple Logo.
- Click on System Preferences.
- Click on Battery.
- Click on Battery on the sidebar.
- Make sure Optimized Battery Charging is checked.
