About this app

AccuBattery 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 remember to unplug your charger.
- Discover how much battery wear was endured during your charge session.
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. 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 AccuBattery 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.

Probably the best battery monitor app there is, helpful in partnership with Android's built-in battery usage data in identifying any issues. One thing I really wish it had is a chart of battery over time. It's a little annoying that it's mostly just a snapshot, and no visualization of data. Simple charts would be very nice.

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

Insanely detailed. I got it just for the battery level charge alert and it's way more than I expected. Update: charge alarm no longer functions unless the app is open when plugged in. Battery health says the last time I fully charged was two years ago, even though I have followed all instructions when charging. Shows gaps of one minute which cause it to fail to calculate. It is no longer useful to me for these reasons. Now I just plug the phone in near me and unplug at around 70-80 percent.
