Check your charger. I found that if I used my iPad's in car charger (2.1 amps) that my phone charged at least that fast. However.....about three days ago I took my phone off my home dock charger and after having been on it overnight, had only 13%. Tried every charger I could find through out the day to no avial. Called Apple when I got home with a completely dead phone and was advised to send it in. Just got email notification today that replacement product is being sent. Wonder if I could have "burnt up" the battery using the higher output charger. What do you all think?
