Recently I found this unknown process (shown without process name) is consuming substantial amount of my phone battery but couldn't identify what process it is. Can anyone throw me some light?
Phone model: LG G4
Android version: Android 6.0 (Marshmallow stock ROM)
Summary & Details (click images for larger variants)
I've tried @Izzy suggestion and here are some useful information from adb shell dumpsys batterystats

adb shell dumpsys batterystats
andadb shell dumpstate
to see if they have some more details (recommend to redirect the output to a file, e.g.adb shell dumpstate >/sdcard/dumpstate.txt
, for easier evaluation). – Izzy♦ Jun 26 '17 at 17:23
