Is there a way to detect if there is a power management issue with an android phone?
I'm rooted on KitKat if that helps.
The phone in question is a galaxy note 4 if it makes a difference.
The symptoms I have are new batteries purchased for the phone going from 40% to dead in a matter of seconds. Recently the phone refuses to charge more than 70% even on a new battery. I'm assuming these are signs of some kind of power management failure.
I'm willing to install any suggested apps if that will help to determine the cause.
