It was factory reset already. Usually turns off within 24 hours, more often then not after a couple of hours. Booting seams normal. Its not trauma related either, I can shake the phone no problem. Then it sits there and just shuts off without reason or notice. I think it happend once that it just turned off while I was using it, but usually I pick it up and its off. The battery is not drained just turned off. Does anyone have any idea what to try? Best Alex
It could be a degrating battery sometimes it dies at a certain % also you can try backing it up and reinstalling the OS unless it is rooted and or it has a custom rom
