Easy and beautiful UI , it's good that no feature is hidden behind subscription. Hope it stays like this. I don't mind the ads. Edit: the new UI sucks, it's not easy to access the information, everything is hidden behind clicks which makes it inconvenient

Actual, legit, full-fledged battery and power management app without requiring root (some ADB commands required). It's not like those 1 or 2-screen useless stuff. It's up there with Accubattery and even better because of integration with battery saver and doze management.

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!

Pro app no ads, the app is the Best battery manager I've used in all my time using Android. My only recommendation allow white list of a certain app or apps if you enabled data saver to not sleep those 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.

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.

All I can say is that this app is legit,it really determined how long my battery was gonna last,my phone often overheats when I play huge games,but when I checked how to save battery online,I ran into the 5 apps,this one was the best and I played a game for hours and my phone didn't overheat .5 Stars. ✌✌

Tried many of these proved to be the best. An application that makes it worth unlocking the bootloader and routing your phone. Battery life has increased significantly.

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.
