My iPhone 5c won't charge. Not your average story.
So I.ve had no issuse with my iPhone until recent about a year after purchase. It randomly just started depleting battery very quickly(3-4hrs per 8hr charge). Now it wont even turn on when charged it shows the battery sign and lightning bolt and a blinking charger head. So I recognize that this is an issue so I go to my carrier store, they use their chargers and it works puts some juice back on my phone, so I buy one of their chargers its not a apple so I didnt have high hopes. The charger I buy doesnt work so I cave and go to the only apple store in my area and its like an hour away. I go there they use their chargers and it warms up fine no issue, they run a diagnositic im all good. So i buy one of their cords and all should butwhen I go home it still doesnt charge.
So my question is why would a phone charge other places with iPhone chargers but when I charge it with and apple charger it wont work?(keep in mind they ran a diagnostic and it says everything is Ok) Ive cleaned the ports out fine too.
iPhone 5c, iOS 8.1.1
