Nice Things About Us
Shawn
Good app, you need to be rooted to use it to it's full potential. You should add a way to support the app with a one time purchase "pro" version instead of the subscription model.
Dave
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!
A Google user
I love it. Please add an option in which the app can automatically turn off the wifi when it's disconnected from a known network, also another good idea you should take into consideration would be to give the option to make the phone call you instead of normal notifications.

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.
Demon Boy
This app is great, recently I install custom rom and the battery percentage was showing inaccurate readings. I only have one problem that is the notification of this app doesn't show on top of any other notifications even after turning notification priority on, please fix this.

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. ✌✌

Thorough reporting of battery stats. You can enable temperature and battery heat thresholds and be notified. One quirk, the app shows which apps are using the most power, but it doesn't show this all the time. I haven't discerned a pattern as to when this report is available.
Sium Ahmad
Clearly this is the best app. Legit stats and even support for dual battery too. The BS features and all of the features are useful and updates keep coming with more optimisations. Loved it and satisfied with this. Highly Recommended! And thanks Dev, keep up the good work ❤️

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.
