Optimize iPhone battery charging:

iPhone has a setting that helps slow the rate of your battery’s aging by reducing the time it spends fully charged.

This setting uses machine learning to understand your daily charging routine, then waits to finish charging past 80% until you need it.

1. Go to Settings ➢ Battery, then tap Battery Health.
2. Turn on Optimized Battery Charging.
