My iPhone 5s is totally unresponsive, with a black screen.
Recently, my iPhone 5s started only charging intermittently, then not at all. I tried very hard to get it charging again, but eventually the 'empty battery' icon disappeared and the screen was left totally black. I have since replaced both the lightning port assembly and the battery myself (without obviously messing up, save tearing the TouchID cable), but have never been able to charge it nor seen anything other than a black screen, despite the new battery. I'm not sure whether I simply haven't fixed the initial problem, or whether I've managed to cause additional problems along the way. Any help would be greatly appreciated.
Is this a good question?
