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 :)

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!

It includes everything I want. The battery status notification shows the discharge current and temperature, very useful for monitoring while using another app.

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.

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.

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.

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.

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 amazed how much you have upgraded your app, keep up the good work, excellent job, with the new power saving options you are killin' it, I have it as my main battery app 5/5 and 10/10
