A great battery app. The notification details. The protection features. The optimization. Evrrything works fine and the reading is accurate too. Definately recommending who want to save and properly use their battery.

The overnight summary is fairly useless without information about what caused the wakes. Ok, so it woke up 12 times. That alone is not actionable.

Currently the best battery app that combines all the useful features from other battery monitoring/dozing apps. I'm obsessed with monitoring my batt and this is the only app I needed and have uninstalled a bunch of other apps.

1. It closes itself and i have to run again and again. If android closes it, then run it again by asking another permission from us while installing your app. 2. Why you read Android Device Configuration Service? You steal all our private data! 3. Your answer was not customer friendly.

Just does what it is meant to do. After the recent update, the charge limit alarm set does not ring. Instead only a vibration is felt. So if I am not close to the phone the battery will continue charging to 100 % . May be I have done the app settings wrong or is it the update?

I update this review, after long development this app already has all the core features plus some additional features all for free. After accubattery development seems to be stop, this app finally can replace that.

Deep sleep doesn't work sometimes. Please fix this. And also please add an online backup option for all our charging and discharging records so that we can't lose our records even after removing the app.

Great app, keep up the good work mate! Feature suggestion: When you click battery usage Android shows you SOT since last full charge ,which isn't accurate if you only charge to 80%. It'd be nice if we had SOT since last time unplugged regardless the charge percentage.

I wish the notification for charging threshold can use custom ingtone or custom a tone. I always missed to charge 80%. Overall this a great app. Good job!
