My iPhone 5 shuts off on its own, boot loop, battery stays the same while charging
HI everyone. I need serious help on my iPhone 5 running the latest iOS.
Last night, I saw that the phone has turned off on its own. I cannot turn it on because my lock button is broken, so I had to plug it somewhere for it to turn on. Strangely after that, it turned off again. I can use the phone while it was charging, and so I filled it up to 100% then unplugged, then it began to shut off again.
That night, I did Reset All Settings. I thought it worked, for my phone lasted until the very next morning. I was able to use it until it began to shut off again.
I plugged it onto the computer, and Restored from Backup. Before that, though, I was in a boot loop. The only way I got out of it is to hold the Home button while plugging the Lightning connector on my phone and onto the computer USB. The restore went successful but the moment I unplugged it from the computer, it turned off.
And so now I'm writing this on my iPhone, it is plugged in. Only thing is that it's been at 41% for so very long.
Please help me. I'm so frustrated for this is the only phone I have. Is the solution as simple as getting the Lock button fixed so I could do a hard reboot?
iPhone 5, iOS 9.3.2
