iPhone 6 not charging via USB to PC
Ok, so I'm having an issue with my iPhone 6 charging via the USB to Lightning cable to my PC. I never had an issue with my 5s and the weird part is, it'll charge to about 75% and then keep going down again. I'm not sure what's happening. Also, the phone keeps restarting itself as well.
The phone is charging via the lightning port plugged into the outlet, but still getting the issue of the phone randomly restarting. HELP! I just got this phone!
