    I'm having a problem with my battery. It does completely, it shuts off, I plug it in, and all of a sudden the battery says that it is half full. I already returned my first 4th gen ipod touch because of this. Should I be concerned? Should I return this one?

    No sorry, once it shuts off, as soon as I plug it in it tells me I half a battery. So I usually just leave it plugged in for a while anyways. When I take it off it appears to have a normal battery life. I just don't understand how the battery can completely drain, and then turn around and tell me it's half full.

    Never had this happen to me. That is quite concerning.

    I just had this like Today. I posted it in my thread "return iPod? Bad battery?" but nobody mentioned that happen to someone else. It dies completely and when it came back on after charging a while, it was at 48%. So should I return it? Also on the apple says it takes up to 4 hours for a full charge but mine takes and around hour and a half.

    You also have to remember about "trickle charge". When you charge the iPod, it's charge over time isn't constant... At low battery it'll be (let's call it) 10units/second (This isn't the actual number, unit just used for example to make it easier to understand). At medium filled (30-40%) it'll be around (let's say) 7units/second. At 50% 5units/second. At 70, 3units/sec. It'll get closer and closer to zero, but never reach it. At this point, it'll be around 100%.

    The rate of charge will vary over time, slowing down, but never being zero.

    Ill probably take it in tomorrow, see what they say. It lasted me 8 hours today with average use and now its charging normal and my battery app doesn't say it still has 62 hours of charge left like last time. I wasen't gonna wait 3 days for it to charge.

    EDIT: Ok, the app said it had and hour and a half left to charge and it was at 25%. 20 minutes later, it's at 24%. should I be trusting the app? I'm definitely taking it tomorrow. its starting to charge down again 23%. Now it's at 17% and 6 and a half hours left to charge ugh.
