Updating with out connecting to power
I just got a new ipod touch, so my ipod needs to run an update before it can finish installing. But my ipod has been sitting at 20% for the past couple if days but won't lose any power. Now do I plug it into the charging cord and finish updating or continue playing the waiting game. I am worried that it will screw up the battery if I do charge it( like a previous ipod I had). Any insight will be greatly appreciated
