I got a question for you all. Recently I put a USB charger in my iPhone, the speaker work the mike work but it won't charge, is there some thing I'm missing or some thing I'm doing wrong, and if so please let me know. I have learn that I need to let my battery drain completely and then recharge it again, is that a true statement, I haven't try that yet and I don't want to, the reason why my battery not drain yet I put the old charger back in but the sound is really low, could hardly hare a thing. So maybe there is another way or I need to buy a new charger. Thanks Help please.
