A few days ago, my iphone 6, while charging, suddenly shut down. As in, the screen just shut off, no shutdown animation (ie. turning thingy) whatsoever. The iphone was about 99% charged when it happened. What I tried so far is: - hold down sleep/wake and home button for some time, while charging - connect to mac, nothing happens, iphone is not even recognized by USB port, let alone iTunes. - let it charge some more (nothing happens, phone even stays stone cold) - try to get into DFU mode: not working I fear the worst, could it be some kind of short circuit? There is no immediate damage what could have caused this to happen. Also, the liquid contact indicator in the sim tray is not red (ie. positive). I'll be going to the Apple store next week, but maybe some of you could also help me.
