Nice Things About Us
SARRAF
I'm honestly impressed at how often this app gets updated. And with each update, it gets better and better. The UI gets even more beautiful with each update. I have replaced my old battery tracker app and doze manager app with this one app. And it does more than those two combined! Absolutely love it.
Vince Wardman
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.

I do not believe the mah measurements are accurate. However, I cannot find an app that accurately displays my charging speed, so it may be impossible. All other aspects of this app are truly amazing! Edit: Working with the development team to resolve the issue.

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.

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!

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.

The overnight summary is fairly useless without information about what caused the wakes. Ok, so it woke up 12 times. That alone is not actionable.
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!

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 :)
