When an ipod is attached, and the battery icon is flashing 'charge' Does the icon stop when the battery is fully charged? Whan I bought my ipod mini last week, i got it home & connected it for a few hours to charge, but the icon never stopped flashing. Does it just flash indefinately? I've had it 6 days, and used it for about an hour a day, and it's nearly flat. Is this a typical usage time for somebody switching on & off regularly, skipping tracks etc?
