I think this app is great! I like the fact that you can assign different sounds or ringtones to different notifications and therefore you are notified when something happens that you should attend to. A very useful 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!
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.

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.
Narendra Athnikar
Just does what it is meant to do. After the recent update, the charge limit alarm set does not ring. Instead only a vibration is felt. So if I am not close to the phone the battery will continue charging to 100 % . May be I have done the app settings wrong or is it the update?
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.

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.

This app is excellent! It provides detailed battery health information and tracks battery usage very well, making it highly reliable. It comes with many useful and important features that work great, and it's very easy to use. I highly recommend it to anyone looking to monitor and manage their battery effectively.

Deep sleep doesn't work sometimes. Please fix this. And also please add an online backup option for all our charging and discharging records so that we can't lose our records even after removing the app.
