Note: How to use Battery Doctor on Android 4.4 KitKat
Android 4.4_r1 removed the possibility for apps to request for the BATTERY_INFO permission, This is the commit https://android.googlesource.com/platform/frameworks/base/+/3714141d287c965ea3451831dd5167f63f8db87b%5E%21/
The reason (issue mentioned) for the commit is unknown.
This permission and the access to batterystats - formerly known as batteryinfo - service is vital for use cases (and apps) dealing with analysing awake and wakeup causes (battery drainers) as this services gives access to partial wakelocks and alarms.

I would like to request a rollback of the mentioned commit. See issue 61975

Here is a Solution from XDA forum by Xposed and download Version 6.2.0, Android 4.3 or older is well, you can flash older ROM
