battery recharge question
If my iPhone battery drains completely and the phone powers down, why is it that when I plug it in to recharge I can't use the phone right away? Instead it needs to charge for *many* minutes before it will turn on. Can anyone explain the reason for this? Very annoying when you need to make a call! The phone has power - seems like it should be able to work right away as long as you leave it plugged in. I guess I'm hoping a better understanding will relieve my frustration.
