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.

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 really enjoy your app, thank you! Good information to stay on top of my battery health and I like all the helpful hints offered as well. I also like how you're continually trying to improve the app by getting user feedback!

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.

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.

Very useful, user friendly. One suggestion. Discharge rate showing correction reqd. MIN shows larger rate of discharge e.g. -657 mah and MAX shows lesser rate of discharge e.g. -156 mah Its because of negative number . Also give another option of one time payment alongwith monthly, weekly options.

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.

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.

Hello, will the app be updated in the future to accurately report capacity for split cell phones such as my OnePlus 7T? I have entered half the design capacity as a work around, but this really isn't a proper solution. Otherwise your app is well written and highly useful. Thank you!
