Same problem. My phone stopped charging with a number of chargers, ALL said they were made for iPhone - the last one I even bought AT the Apple store. Someone gave me a cheap knockoff charger and it worked, it was great - then my rabbit chewed through it last night, and again none of my other, certified cables will charge the %#*@ thing. Never had this problem with androids, and it’s obviously not the port as the one charger did work.
