About this app

Developer Description

AccuBattery monitors battery health performance via science

AccuBattery 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

AccuBattery 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 AccuBattery 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

- Measure real battery capacity (in mAh).
- See how much wear your battery sustains with each charge session.
- Look up the discharge speed and battery consumption per app.
- Remaining charge time - know how long it takes before your battery is charged.
- Remaining use time - know when you will run out of battery.
- Screen on or screen off estimations.
- Check the percentage of deep sleep, when the device is in standby mode.
- Ongoing notification for real time battery statistics at a glance.

🏆 PRO FEATURES

- Use Dark and AMOLED black themes to save energy.
- Access to historical sessions older than 1 day.
- Detailed battery statistics in notification.
- No ads

We're a small, independent app developer with a focus on quality and passion for battery statistics. AccuBattery doesn’t require access to privacy-sensitive information and doesn't make false claims. If you like the way we work, support us by upgrading to the Pro version.

Alexej Kern

Sehr schöne und informative App. Ich sehe jedoch beim Aufladen nur bis 80%, um den Akku zu schonen, einen kleinen Denkfehler: Sagen wir mal, mein Akku ist neu und hat 100% Kapazität. Wenn ich ihn dann immer nur bis 80% auflade, nutze ich nur 80% der Kapazität, was dasselbe ist, wie wenn ich einen 2 Jahre alten Akku mit 80% Kapazität vollständig auflade. Wieso sollte ich also die ersten zwei Jahre auf mehr Akkulaufzeit verzichten? Ein Akku altert ja auch mit der Zeit.

Isn't perfect by all means but doesn't require any developer level permissions and entirely based on averaging the battery's capabilities, takes its time and all, if checking a used phone before buying this isn't the app better go with the combo of "abattery & Shizuku". Still it works but has it's own limitations other than that I would like if it could also show previous data like battery cycles too.

The notification icon has too few options. I have another app to show me my airpods battery status and it has the exact same icon. As I already have my phone battery percentage shown on my right, I would really appreciate, if your icon would be something like a battery with letters AB on it, so I just know its working correctly on backround.

people claim that this app would tell me how long it would take to charge my phone and it does not do that. it does not say on the main screen nor it doesn't say anywhere

screen off result after battery health of 25% shows very irregular and inaccurate values ... didn't you guys check before releasing a buggy update?? Will not email or share any more information rather than this here, so do make fixes ASAP
