Bought this phone used about 16months ago. It was in great condition when I received it, and I have taken good care of it since. The phone started randomly restarting during the colder months of the year and I found that it qualified for the battery replacement through apple. The battery was replaced by the Genius bar (no charge to me) and the phone worked great afterward. About 6months (give or take a month) ago, the phone began to heat up under normal - heavy use and freeze. It took about 30s or so and the phone would reboot. I’m guessing it would do this because it didn’t want to damage the hardware. Fast forward to today, the phone freezes and restarts at least once a day on light - normal use. I called Apple and they told me that they could take a look at it but most likely they would just issue a replacement phone for more than I was willing to pay. I would replace the battery again, but I don’t think this is the problem. Have I fried some other hardware inside the phone? Not sure what the problem is. Also, I’d like to note that my charger began to show some signs of arcing (also about 6 months ago) inside the lightning connector. I’ve cleaned the charger multiple times and decided to buy another one. This one still looks pristine, but I’ve only been using it for about a month now. I’m fed up with this phone, but cant sell it with it’s problems. I’d like to at least figure out whats wrong with it and see if I could fix it.
I wouldn’t be surprised if the battery was making such problems. First thing that comes to mind is trying with a different battery. If that doesn’t work, and a new charging port assembly doesn’t help, you might be having issues with your motherboard.
Are you using original, Apple charger and Lightning cable? Cheap bricks may not be properly grounded and that might be causing the arcing.
