i think i may have just messed up my iPod Mini. it arrived this afternoon, i accidently pressed a button whilst getting that plastic seal off it, i quickly noticed that the meter was about 3/4 full. so i turned it off, stuck it into my PB for its 4 hour charge... only i get a little curious about USB2 charging, wondering if it will still charge if my machine is sleeping. so; apple menu, sleep. my Mini disconnects, the battery meter is saying its full so just to be sure i stick it back into my PB and the lightning bar shows its fully charged. smashing! or is it? im a little worried about it now, the meter has dropped down a few pixels and ive only been playing with the menu for a few minutes. whats up with it? should i go stick it on charge now or is it really full?
