About this app

Accu​Battery 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
 
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.
 
- Monitor how much battery your device is using
- Know how long you can use your device when it’s active or in standby mode
- Find out how much power each app uses.
- Check how often your device gets woken up from deep sleep.
 
🔌 CHARGE SPEED
 
Use Accu​Battery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to find out!
 
- Check how fast your device is charging when the screen is on or off.
- Know how long it takes to charge your phone and when it’s finished.
 
HIGHLIGHTS
 
- Measure real battery capacity (in mAh).
- See how much wear your battery sustains with each charge session.
- Look up the discharge speed and battery consumption per app.
- Remaining charge time - know how long it takes before your battery is charged.
- Remaining use time - know when you will run out of battery.

Best battery health and charging app that I've used of the many I've tried. The only issue (it makes sense, it is trying to help as much as possible) is that it by default has the 80% charging alert that was a bit unexpected at first but it can easily be disabled. Otherwise it gives you all the info you'd want and more at your fingertips. Very very well done

An amazing app to learn how to manage phone's battery health. The recent UI redesign is subtle, yet beautiful. I totally loved it. I would wish the ability to see the charging amount (total energy) represented in Wh or even kWh depending on user's preference. This should be really easy to implement as a feature because they have all the info already.

-1 * for obnoxious full screen noisy ad on launch. Recently, battery health does NOT work consistently - just charged from 8 - 100, app says last full charge was 14 days ago. Feb. App still randomly crashing. Recently, app has been inexplicably crashing or, at least, evaporating from the notification area. Is there crash logs or a debug settings that can be enabled to capture the crash log? This on Android 12; Continues to work just fine on Android 7. I've never seen a crash on the older phone.
