iPhone randomly shuts off!
I had a cracked screen which i got it replaced. After 2 weeks, while on call i use to hear noice buzz.. later which stopped and not the iphone shuts off automatically and randomly. It shows loading circle as if it's shutting down. After i switch on the iphone the battery is half down and sometimes it's restarts again at home screen. Someone told me that the ground wire is loose..
can you tell me what could be the problem and if it's ground wire, where is in inside so i can rectify it.
If my iphone is at 75% battery and if i restart it, the battery jumps to 5% or less..
Is this a good question?
