iOS 13 uses Optimized Battery Charging to slow the rate of battery aging by reducing the time that your iPhone spends fully charged. iPhone uses on-device machine learning to understand your daily charging routine. Charging in this way reduces the wear on your battery and improves its lifespan.
How it works
The iPhone learns your daily charging pattern and predicts how long the iPhone will be on the charger when you go to bed overnight. After a few weeks, it will learn that you consistently wake up and take your iPhone off charge at 6 AM, for example. With this prediction of daily behaviour, Optimized Battery Charging prevents your phone from fully charging to 100% as soon as you plug it in. Instead, the iPhone battery will charge to about 80%. This means it will stay at around 80% for most of the night, even though it is connected to the charger the whole time. Just before 6 AM, the iPhone will then finish charging and should hit 100% just as you take it off the charger to get on with your day.
How to switch it on
Optimized Battery charging is on by default when you set up your iPhone or after updating to iOS 13. If you notice that your iPhone is often only partially charged—for example, if you don’t charge your iPhone overnight—you can go to Settings > Battery > Battery Health and turn off Optimized Battery Charging.
