About this app

Accu​Battery displays battery usage information, and measures battery capacity (mAh) based on science.
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.
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.
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.
- 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.
- Use Dark and AMOLED black themes to save energy.
- Access to historical sessions older than 1 day.
- Detailed battery statistics in notification.
- No ads
We're a small, independent app developer with a focus on quality and passion for battery statistics. AccuBattery doesn’t require access to privacy-sensitive information and doesn't make false claims. If you like the way we work, support us by upgrading to the Pro version.

The features are comprehensive and excellently presented. But it keeps crashing randomly, every several days, and ONLY while charging, leaving my phone to silently push all the way to 100%. Since the charge alarm is the main reason to have the app, this sucks. Would be an easy 5 stars if it didn't persistently fail at the wrong time.

This app used to be a lot more useful, but now it's degraded significantly. Suspect it's been bought out or something? No longer reliably tracks my charge/discharge sessions, takes several seconds to open sometimes. Intrusive ads. Clearing data as suggested did not help. Uninstalled since I'm good about manually unplugging at 80% charge now to avoid unnecessary battery stress. Only thing it's still useful for me is seeing charging current and temperature.

Now there is an easy way to dismiss the full page ads. The damned ad is full page and I see no way to dismiss it so your reply doesn't cut it. I don't mind small ads and which I sometimes click on. Now has obnoxious full screen ads so I'm dropping AccuBattery from 5 to 2 stars. Works fine. Signals 80% charge and at intervals there after. My phone doesn't support full charge detection. Has ads but they are not obnoxious and sometimes are useful. I recommend AccuBattery for Android phones.

Unfortunately ads are a necessity that helps keep the key functionality in the app free for all users. We've done our best to choose ads that we ourselves would find acceptable in other apps. We decided to add the new ads because we see a lot of room for exciting new features and want to be able to focus more of our time and effort into development
