Has anyone else received a new phone that had no charge in the battery? Reason I ask is: Received two iPhones today. One showed almost a full charge the other one was so low that it wouldn't turn on until after it was plugged in to charge for a 5 min or so. It's fully charged now but I wanted to wait and see how long it will hold the charge before activating it as I don't want to deactivate old phone and then have the new one need replacement. So I'm wondering if my problem is unique - if so it might indicate a defective phone.
