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.

Ratings and reviews

My last phone stopped charging automatically when it reached 80%, for maximum battery life. This app only alerts me with a wimpy, 1- second chime that is easy to miss, allowing it to continue up to 100%. I would rather have it stop automatically, or at least be loud and last for 10 seconds so I won't miss it. I wish I it would also alert me LOUDLY when charge drops to 20%, to remind me to plug in. All phones should be able to be limited to 20%- 80% for maximum battery life.

I used this app for a long time, and it's absolutely fantastic for anyone who wants to take care of their phone's battery. The most useful feature is the charge alarm, which helped me maintain the habit of charging only up to 80% to prolong battery life. It provides incredibly detailed stats on battery health, capacity, and which apps are draining the battery. It takes a few charge cycles to become accurate, but the insights it provides are invaluable. A must-have tool for every user.

This is incredibly frustrating. Why does the app suddenly shut down its background processes only when charging? Other apps don't, and they still run in the background without any issues. I have excluded this app from Battery Safe Mode to none, meaning it should always be running under any circumstances (unless the phone is turned off), but that is not the case. If this continues, supporting tools such as battery charging alarms will be useless, because the application is completely closed!

What’s new

• Fixed overlay rendering behind rounded screen corners.
• Charging page: show why a charge cycle is not included in battery health calculation.
• Health page: fixed display of "charged for _ mAh total".
• Charging / health: improved handling of long sessions with disabled charging (like Sony's 80% charge limit) - works now for calculating health.
• Updated and improved purchase handling.
