I used battery mix and saw that android.process.acore uses 90% battery.
But while my phone is in idle the battery is awesome. 1% in 8 hours, but if i start using it, the battery drops faster then normal.(Not comparing to while the phone is idle, but comparing to when it was stock).
I was wondering if it also have something to do with the modem? I am using the Rogers I317MVLALJ2.
and the kernal is

When i was using the CR3.5, I do not believe I saw acore process requiring root. or even saw it at all.
