How to Enable or Disable Optimized Battery Charging in iOS 13

The lifespan of your iPhone’s lithium-ion battery tends to be longer when it isn’t fully charged. The new optimized battery charging feature in iOS 13 learns from your daily charging habits. It’s using on-device machine learning to improve your battery’s lifespan.

With the optimized battery charging feature enabled, the battery in your iPhone is kept below 80% until a full charge is needed. This helps reduce unnecessary battery aging and can also improve performance.

By default, iOS 13 enables the optimized battery charging feature. If you know that you’ll need your phone to be fully charged, you can turn off the optimized battery charging feature. Read on to find out how.
