So far, I have been using another app, but it was missing a few things that I found here. To sum up, it's good. The only thing I need is for the application to disconnect charging after setting the desired value. Just like I have on OnePlus. I don't know why, it resets several times. "Screen on" should work until the phone is turned off. I checked on three smartphones. It's the same everywhere. After some time, instead of continuing to count, it starts from zero.

The app is very good if it is true that it protects the battery I highly recommend it

John Doe

Great app! Highly recommended.

Hadyan Prawira

This application is very helpful, complete features, the UI is very simple and neat, easy to use, I also have a suggestion for developers to create a feature like always on display/ambient mode, so we can see the voltage and battery health without having to open the application first. first, hopefully this feature will come, thank you + keep up the enthusiasm ๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘

THIS APP BEATS MY EXPECTATION, tells you your battery health, input output power, also tells your which apps taking most power, and the app tells you to disconnect at 85%-90% to prolong your battery health. And a lot of other options, like graphs. You get all these features for free, Highly recommended

After few cycles all is going well. The app is good but I think the measurements with screen on time are wrong. The percentage is way too high compared to other famous battery apps. Just doesn't make sense to use 4% screen on in less 5min. 4% within 20min with screen off time combo is more accurate from accu battery. Hope you fix it
