UPDATE- thanks for fixing the notif bug and %icon. It would be great if you also add CPU temperature on notification bar. Because I also monitor my cpu temp to avoid damage. A format like "c41° b37°" to differentiate cpu/batt temp or on-top of each other just like inside your app "show percentage and temp". Thanks :)

Works great. Accurate with a lot of info. I just wish there was a one-time purchase option. I generally refuse to subscribe/rent software, but if the yearly amount was less I would make an exception for this app.

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.

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.

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.

Great App! I have a smaller phone with minimal battery life so being aware of all the aspects of my battery are key in maintaining optimal battery health. This App has everything and the ads are discreet and don't interfere with the App operation or function. Excellent!

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.
