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's almost everything I've been looking for. What it offers was worth upgrading to the pro version. As of right now, I have two suggestions to improve the app. 1. In the charging section, inform users at what percentage they should charge for peak efficiency. 2. Provide greater UI customization options. In particular, give pro users the ability to change the bright green at both the top of the screen and the "show x sessions" icon. Although I've gotten used to it, it's too bright for dark mode.

Good app! Clean, professional interface. Seems reliable and like they care about their methodologies (and continuing to developing them). Initially downloaded the app just to compare different chargers, but quickly paid the (iirc - optional?) $5(?) for premium or wtv, but mostly cuz it was one of the best apps I've honestly ever used. It works, and minimal bloat - hope it stays this way!

Very useful app. I was testing my battery prior to replacement and it has all the stats I want. I think long-term it'll be a great bit of data to look back on. Only downside is after installing the new battery, I think the app has got a tiny bit confused (I assume it's expecting degradation, so the stats don't quite make sense). Perhaps needs an option for different profiles or a reset?

What's new

• New Material 3 style UI.
• Added navigation rail for landscape mode.
• Optimized app loading, now shows progress. First launch after upgrade may take a while, need to apply database changes.
• 2.1.1: update history sessions card style, fix rare crash in charging tab
• And many, many more changes and fixes.
