Prevent overcharging
Leaving your phone plugged into a charger can lead to overcharging, which over time shortens your
battery’s life. Overcharge protection keeps your battery healthy by limiting its charge to 80% if it’s been
plugged in for three days.
When Overcharge protection is limiting your charge, you'll see in the status bar.
To fully charge your phone from 80%, just disconnect it from the charger and plug it in again.
To turn this feature on or off:
1. Go to Settings > Battery > Overcharge protection.
2.
Turn it on or off .
