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.
 
HIGHLIGHTS

I recommend this app to everyone, it can help you prolong the life of your battery and also shows you how degraded your battery has become. The only suggestion I'd make is to combine in the history multiple back-to-back charge sessions such as those caused by a loose cable/port. Like at least wait 1-2 minutes before changing state (charging/discharging)

Very useful! I like the alerts for when the battery reaches a specific point because I get the notification on my watch. The statistical data is great too. The only thing I'd like to see added is instead of a notification for my battery percentage up top I'd like to be able to change that to say my battery temperature, CPU temp or GPU temp. Other than that, this app is well worth buying the Pro version

I was hesitant at first, but after using it for a couple of weeks and following the charging advice, my battery health has improved and will no doubt allow my phone to last longer. I'm trying to figure out the difference in the paid Pro version and would suggest a tool that would stop battery charging at 80%. Prior to using the app, I always charged to 100% and had no idea it was damaging
