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.
Savita
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.

Thorough reporting of battery stats. You can enable temperature and battery heat thresholds and be notified. One quirk, the app shows which apps are using the most power, but it doesn't show this all the time. I haven't discerned a pattern as to when this report is available.

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!

I'm amazed how much you have upgraded your app, keep up the good work, excellent job, with the new power saving options you are killin' it, I have it as my main battery app 5/5 and 10/10

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 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.
João Pedro
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.

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.
