my iphone 5 recently had its battery replaced coz it had died.and after a week, it overheated when i was watching utube vids. The battery was at 50%,i let it cool and fell asleep. nxt morning it wouldnt turn on and i have tried the sleep?wake button and home button , but that was not good. ive also tried dfu mode, no luck. i also charged it for around 2 hours and still no luck.
but surely the battery shouldnt be the problem when the baterry was replaced excatly a week ago.
