I really like this application. Over the years of using Android I have tried many battery monitoring tools. This one has a great UI, and provided the data I want in a easy to read format. Thank you

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?

Still exploring the whole functionality but it has been great experience so far. Thank you for your hard work Wishing that it could directly make a charge cut off but it seems like this is out of the scope

I wish the notification for charging threshold can use custom ingtone or custom a tone. I always missed to charge 80%. Overall this a great app. Good job!

Excellent app for whatever you need to know about your device's battery, charger, charging speed and all. Useful features available for battery protection like level alarm, temp alarm etc. Have been using it since 2.5 years in every phone I own. Definitely recommended whether you are a basic or advanced user.

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.

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.

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.

Pro app no ads, the app is the Best battery manager I've used in all my time using Android. My only recommendation allow white list of a certain app or apps if you enabled data saver to not sleep those apps
