Chosen Solution

In the morning I woke up, and my phone was dead. So I shrugged and left it to charge while I was at school. I came back after around 7 hours, and it still had no charge, but it said it was charging. So I moved it to another outlet, and still nothing. I tried another charger, nothing. Then I tried to plug the charger into my computer. Still nothing! I tried ANOTHER charger in ANOTHER port, and it still won’t charge. I tried taking off the case, blowing into the charging port. Nothing. So I’ve turned to the internet. My iPhone has always had a bad battery. It would drain very quickly, and when it says 30%, or something pretty low, it would just die. But I always keep it plugged in, so it’s fine. But I’m so confused, so, please help!

Your battery is faulty. The battery also sends data information to the phone besides voltage. Buy a new battery and your phone should be fine they are not that expensive. You can use this guide.

Have you try a hard reset by pressing and holding both the “Power” button and the “Home” button at the same time, till you see the Apple log?
