About AccuBattery
AccuBattery monitors battery health performance via science
AccuBattery displays battery usage information, and measures battery capacity (mAh) based on science.
❤ 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
AccuBattery 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. However, in practice, these figures frequently fall short of expectations. - Keep track of how much battery your device uses. - Know how long you can use your device when it’s active or in standby mode
