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 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.
Pratham Desai
Easy and beautiful UI , it's good that no feature is hidden behind subscription. Hope it stays like this. I don't mind the ads. Edit: the new UI sucks, it's not easy to access the information, everything is hidden behind clicks which makes it inconvenient
Shaun
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.

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.
Michael Clark
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!

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.

Thanks for the app. I am using this app along with your speed indicator and after the latest update both of there notification icon are fighting for the priority please help as it is a bit annoying to watch both icons continuously "shifting".
