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.

Ratings and reviews

It just works. It's stable, reliable, easy to use, easy to read, I can find the information I need at any given moment quickly and without frustration, it uses minimal system resources compared to nearly any other 24/7 monitoring service, and it is frequently updated by active developers who stay on top of changes in the Android AOSP. Can't ask for more. I've been using it for 10 years across 4 smartphones, and it's been reliable the whole time.

I'm very pleased with this app. I was having problems with my phone not charging. my charger works for other things but it was older. but the new charger wasn't working well.. I cleaned out my phone port which helped a little. I used AccuBattery app and followed all the instructions. now my phone charges rapidly. even when hooked up to the connection in my dash. I would recommend this for maintenance and visual health.

I've been using Accubattery for several years now and upgraded to the Pro version shortly after. It's literally the best your going to get with regards to monitoring you're battery. Some of my favorite features for instance the ability to monitor how much each apps how much power they're using, also I can watch the state of the battery the health and the best way to charge it you know which would be with a lower amp charger if you want the battery to last longer. Try the free version!!!
