I'm not an expert but it could be your I home. I have heard that some methods of charging work better than others. Try plugging it into your computer to charge or an outlet and see if it changes. If not than i don't know except, try turning it all the way off when not in use and see if that works. If not that, then contact apple.
hey did you leave it on that might be the problem . i got the 4g too and i always turn it off if im not using and i always charge it when im using . get a charger that can plug in into a computer if you have a job that uses computer
Your battery is slowly running out.
The more you unplug and replug and unplug and replug your Ipod
, it begins to degrade itself. My macbook MUST be plugged in, as its battery can no longer hold a charge. I'm buying a new one soon!
Take the Ipod to the Apple store and buy a new battery, get some help from the Apple geniuses, etc. Search online for a 3rd party battery as the Apple ones tend to be expensive.
ALSO, don't buy a new battery yet. It's a waste as they are VERY expensive, and your ipod can still last 7 hours on standby. My macbook doesn't last a second.
I'm not too familiar with the Ipod touch, but on mac osx, at the top bar at the top of the screen, the battery icon beside the volume on the right not only tells how much battery is charged, but how much life your battery still has... (How many recharges it can handle)
