So the charging unit that came with my phone, legitimately in that plastic iPhone 5c case w/ the iPhone, will not charge my phone but rather prompt this message: "This cable or accessory is not certified and may not work reliably with this phone."
If I ignore it, and leave my phone connected to its charger, the battery will lose all charge over time.
My main problem starts here though, last week, I brought my charger to the verizon store to replace it, but when I got there, it was charging w/o any problems. So I brought it home again and it worked until now, a week later. The same message is popping up and it won't charge.
