Nice Things About Us

I love it. Please add an option in which the app can automatically turn off the wifi when it's disconnected from a known network, also another good idea you should take into consideration would be to give the option to make the phone call you instead of normal notifications.
Toby Pollock
It includes everything I want. The battery status notification shows the discharge current and temperature, very useful for monitoring while using another app.
Rizky Darmawan
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.
Dio Tony
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

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.

It really helping to save battery for Android 11 when few apps prevent Android to into deep sleep. The Lite doze options is very difficult to understand, please provide option to disable all lite doze settings as most people want deep sleep after screen off.

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
Vince Wardman
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.

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.
