My Google Pixel Xl suddenly shut off last night while I was using it without me doing anything. It then would not turn back on. It would go from the white Google Screen and then turn black over and over again. This morning my phone seemed to have turned on when I went to check. I used it for about five minutes and then it shut off again. It turned on again a minute later. I was on my phone again and then it shut off again. It won’t turn on now. It just keeps cycling between the white screen with the google logo and a dark screen.
