Will it damage my iPod battery if I keep it plugged after the charge is complete?
It could shorten the battery life. The best thing to do is to drain the battery right before it dies then charge up to to 100% then Unplug it. That'll keep the battery alive the longest
No, that story which zeeko told was for old butteries not for todays
Zeeko is right although keeping it plugged in when it passes 100% won't do terrible harm
No, but I know a trick if you go into your settings go to brightness then if you lower the battery life it will keep the charge more longer......
