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.
- Screen on or screen off estimations.
- Check the percentage of deep sleep, when the device is in standby mode.
- Ongoing notification for real time battery statistics at a glance.

Past few months, battery health does NOT work consistently - just charged fro 8 - 100, app tells me 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.

Works great on some phones, but completely garbage on others. On the Pixel 7 Pro, it works great. But on the OP9Pro, it doesn't even start registering the discharge rate until you open the app. So you could use your phone for hours, open the app, and it will look like you just started using your phone when you opened the app. If that issue was fixed, it would easily be a 5 star app.

Great app, but lacking 3 important features. This app would be 5 stars if it had: 1) Temperature alarm, 2) Customizable sound when charger is disconnected, and 3) Alarm when the battery drops to a certain level such as 30%. High temperatures and extreme states of discharge are destructive to lithium ion batteries. This app does not offer alarms or proof to the contrary addressing those issues. This app could add a feature that makes a sound when charging is disconnected since Android doesn't.
