Reboot loop when plugged in, no response otherwise
After a short drop my 5s was off and non responsive.
Plugging it in to the wall results in a reboot loop. Occasionally the screen will blink red after the apple logo right before it reboots, but most of the time the screen just turns off and then it reboots.
If I unplug the phone any time during the reboot process the screen immediately turns off.
The phone does not attempt to boot connected to my PC, although I can get it in to DFU mode. I would rather not lose the non-backed up media on the phone, so want to try hardware repairs first.
My first thought is a battery issue as it goes dark when unplugged (plus battery life has tanked lately anyways). Anything else I should check before opening it to check the battery connections or ordering a new battery?
