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.

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.

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.

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. ✌✌

Very complete interface, lots of monitoring to improve battery life. Just amazing. Also liked the way ads are served, in an on demand way for free users. This non intrusive way is much more comfortable for users, trading off revenue. But UX is extremely improved this way.

Still exploring the whole functionality but it has been great experience so far. Thank you for your hard work Wishing that it could directly make a charge cut off but it seems like this is out of the scope

I think this app is great! I like the fact that you can assign different sounds or ringtones to different notifications and therefore you are notified when something happens that you should attend to. A very useful app!

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.

This is a pretty great little app. I couldn't get my phone to cool down so I went searching for apps that detect battery usage. This one was actually able to cool my phone down even after a factory reset couldn't.
