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.

After replacing the display on my Note 9 I noticed the damage to the battery I caused was having an effect. I needed an app to see what was going on with my battery. This app helped me track the degradation of the capacity and to decide to change the battery. The new display uses more power than the original and the burn-hole in the end of the battery were too much. It is easy to use and once you play with it a bit you can get some useful data.

More than expected, even with unpaid version. An inordinate amount of battery information giving me better control of my devices. Without the ability to swap batteries, once they go, so does the device. This has given me an extension of my phones and tablets battery life without any noticeable effect on speed. Tweaking the alarm and the occasional shutdown of the app is well worth the effort. Try this one.
