I recently bought an iPhone 4s, I've always had problems with charging (had to take out and re-plug the charger a few times before the phone would start charging) but now it really won't charge no matter how many times I try! The phone is brand new so there can't be a problem with the battery right? I also have ios 7 installed, could that be the problem? Thanks in advance!
Added (1). I already tried restarting the phone but it still doesn't charge
