Chosen Solution
I plugged my iPhone 5s into my computer and this happened: My phone went black but the backlight remained on and it showed it was connected to iTunes. I then restarted my iPhone (Home+Power Button) and the phone turned off but didn’t turn back on again. (No backlight or Apple symbol…etc). Ive tried: Charging overnight Charging with different chargers DFU Mode (didn’t show in iTunes) Cleaning the charging port Switching the battery What can I do? If anything? Note: Not water damaged in the least bit. Phones in perfect condition.
Power issues are a bit tricky. The first thing to check will be the charging port. Remove the battery and then try plugging it in and see if you get a apple logo. If you get a logo that loops over and over then its possible you have a bad battery and wont take a charge. If you dont get a logo i would try a charging port. Wish you luck. if nothing helps then it could be a bad Charging IC on the Logic board and may need Board Repair.
