About this app

🏆 Designed to keep your battery in the best shape you can – AndroidHeadlines
Accu​Battery protects battery health, 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. Scientific research shows that battery lifespan can be extended up to 200%, when you charge your device to only 80%.
- Use our charge alarm to prolong your battery lifespan.
- 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).
- Use the charge alarm to prolong battery lifespan.
- 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.

Very accurate with good information. Attractive UI. Has a nice, adjustable alarm that triggers when the charging battery reaches the charge amount that you set. Surprisingly it lacks a widget. If you only charge your battery usually only to 80%, it will extend your the life of your battery. I used this app on my last phone for 4 years and the battery was still in pretty good shape. Great app that really does work. It is worth the money for the pro version.

I like the idea, and the app is very well put together. However this app has never been updated in the entire time I've had it. The Algorithm has no comprehension of super fast chargers. But honestly what bothers the most is the endlessly long amounts of data and information they mine from the phone. There is absolutely no reason an app needs to connect that much. In the end its poorly built and I wish I never spent a penny for what amounts to an intrusive and horribly bad security leak.

I decided I wanted this app when my Pixel 4 stopped displaying the percentage inside the battery display in the notification bar. It is the only reason I have this. Works well, but unfortunate that it now has to occupy another notification space and sometimes I can't see it when I have too many notifications. Since I'm just here for the percentage, it would be nice if the percent showed up in the notification drop down. Very clever, all that detailed tech stuff, but I don't care about that.
