My iphone turns off by itself and I can't turn it on. It turns itself back on after several hours
I just bought iphone 6 about 4 months ago and since updating to ios 8.3,my phone would turn off b itself even it had 100% charge. After a couple hours connected to the plug,it would boot up by it self. I don't know whether it is something to do with ios 8.3 but I only got this problem after updating
iPhone 6, iOS 8.3
