I've a 1st G ipod touch with 2.2 firmware. Just got it recently, refurbished, so sadly I've no warranty (I think) the thing is that I use the ipod most of the times just to watch movies, I don't lower the brightness, or turn off wi-fi since I'm constantly using it. The battery lasts about 4 1/2 to 5 hours. Is this normal? I don't know if it is. What I think is not ok, is that the battery of the ipod seems to be running out even while plugged in to my laptop. I mean, plugged in while using to watch videos or surf with safari. It charges without problem if I leave it alone, though. I was wondering if there's something wrong with it or if that's how it's supposed to work.
