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!

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 :)

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 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!

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

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

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.

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.

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.
