iPhone 4 won't turn on or charge???
So I've had my iPhone 4 for about a year, and it's been running absolutely fine for the entire time I've had it - up until now! For the last three days, it was telling me it had 74% battery life, no matter how much I charged it or didn't charge it, it stayed on 74% which was weird, but I thought nothing of it.
Yesterday morning when I woke up, my phone wouldn't turn on. I assumed it was dead on battery so I plugged it in so it could charge up. It turned on fine, but then after about thirty seconds it went dead again, even though it was still plugged in. The screen was black, and the apple logo just flashed on and off the screen, but it wouldn't turn on OR charge, at all.
Last night I charged it for the entire night, but it DIDN'T charge at all, the apple logo just flashed on the screen ALL NIGHT LONG!!!
It's turned on about three times out of however many times I've tried to get it going, the screen just flashes with the apple logo, and it won't charge!
I've tried holding down the home and hold button, it doesn't do anything.
I've tried to restart it, but it won't let me.
Someone please help, it's incredibly frustrating and I really need my phone!!
iPhone 4, iOS 7
