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.
 
❤ BATTERY HEALTH
 
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.
 
📊 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

Works exactly as advertised! Lots of good details! When I connected my device in-line with a tester, the numbers were very close. It's nice to have a way to "double check" both my meter, the chargers, and my device being charged as well. As soon as I can purchase the Pro version, I absolutely will. Received errors when trying to purchase the upgrade.

Helps me keep track of my battery's health, and to optimize it by controlling which apps are draining it fastest. This is an app that really grows on you over time -- and now that I have been using it for three or four months, including my transition to a brand new pixel 7, I'm even happier with it. Really helps to understand what's happening with the battery and how to help it to live longer.

I'm not convinced about the estimated battery life. It seems to change considerably between estimated battery life when charged and then when it's done you switch to the health option and the battery health bar in mah shows something completely different. Yes, I have all the options that enables the app to run without restrictions. I'm just hoping there are future updates to make it more accurate. In conclusion it is a good app otherwise.
