❤ BATTERY HEALTH
 
Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity.

- Use our
charge alarm
to remind you to unplug your charger.
- Discover how much
battery wear
was endured during your charge session.
 
📊 BATTERY USE
 
Accu​Battery measures the
actual battery usage
using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate.
