Someimtes when I plug in my ipod to my wall charger, the battery icon will show the power plug rather than the lightning bolt, indicating that's fully charged when in fact it nowhere near fully charged (right now it's showing the plug and at 55%). I keep unplugging and plugging back in but it refuses to show that it's charging. If the icon shows the plug, is the iPod not charging? I think I remember I left my iPod "charging" when the icon showed the plug and after a while the battery %age didn't change.
