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!
Alexandros Yintsis
Great app, keep up the good work mate! Feature suggestion: When you click battery usage Android shows you SOT since last full charge ,which isn't accurate if you only charge to 80%. It'd be nice if we had SOT since last time unplugged regardless the charge percentage.

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.

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.

Hello, will the app be updated in the future to accurately report capacity for split cell phones such as my OnePlus 7T? I have entered half the design capacity as a work around, but this really isn't a proper solution. Otherwise your app is well written and highly useful. Thank you!

All I can say is that this app is legit,it really determined how long my battery was gonna last,my phone often overheats when I play huge games,but when I checked how to save battery online,I ran into the 5 apps,this one was the best and I played a game for hours and my phone didn't overheat .5 Stars. ✌✌

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.

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

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.
