Hey there!
Tonight, I had a weird experience with my phone as I did not expect the phone to be dead in the morning. I checked the built in battery monitor and saw something extraordinary, as shown in the image attached.
I'm not an expert but I do know more than the average android user so I would guess that the problem was either a battery failure or it can have something to do with that I rooted my phone yesterday night. Thank you in beforehand! imgur: the simple image sharer
