If your battery stopped charging at 80 percent

Venustas Optimized Battery Charging helps slow down battery aging by minimizing the time your battery stays fully charged.

Your battery might get a little warm while charging. To extend its lifespan, if the battery gets too warm, our software may limit charging above 80%. Once the temperature drops, charging will continue.
