Actually my iPhone was functioning quite well till Yesterday as it ran out of battery and switched off. I charged it a bit (12%). Then, I unplugged it and made some phone calls. As I plugged it again, the sign for charging was not there. I also, connected it to my laptop. The laptop didn't recognize it. I then, used other cables and batteries. It didn't function. I switched it off and on several times, nothing changed. I just left my iPhone plugged. After something like an hour, it was charged for something like 10%. What the hell is wrong with it? I don't think that its battery life has ended. Cause I have it since something like 2 years. I appreciate any help!
Added (1). Thanks, but why doesn't my Laptop recongnize it so that I can backup my data?
