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've been using this app through my last three phones. It's interesting to see more data about my battery life, it's environmentally friendly to unplug when you're full and the reminder helps with that, and on my last trade in, my phone was in better condition and worth more than estimated. I attribute that to the battery health I maintained by using this app!

I was looking for something to let me know what the battery temperature is and found AccuBattery. This app provides the temperature and a whole lot more. The pro version is definitely worth it! It answers everything you're wanting to know about the battery and charging system in your phone. It also helps the battery last longer saving you your hard earned money.

What’s new

• Charging page: show why a charge cycle is not included in battery health calculation.
• Health page: fixed display of "charged for _ mAh total".
• Charging / health: improved handling of long sessions with disabled charging (like Sony's 80% charge limit) - works now for calculating health.
• Updated and improved purchase handling.
