Hi I have a new ipod touch 4g. When I go to bed at night the battery level is about 80%. I put it in standby mode and then 9 hours later the battery level is less than 20%.

Is anyone else having this problem with their touch 4g? Or should I exchange it?

ipod touch 4g, iOS 4

    first question I have is was the 80% a result of a partial charge done just before going to bed, that created what's known as a "surface charge"?

    Mine's been sitting idle for two days with no reduction in charge level. I do believe that 9 hours in standby mode (whatever that is) will affect battery life, so turn it off instead.

    I was hopping this has been addressed. I have a previous iPod Touch and have gotten into the habit of turning on Airline Mode when not in use, much faster than turning the device off. I wish a button/switch combo could be assigned to Airline mode...that would be nice.

    I have also turned of notifications as this seems to affect battery life as well. I kind of found them annoying anyways.

    Thanks for the replies guys.

    David: I think it was fully charged to 100% and then I just used it for an hour or so running down the battery to get to 80%. But, I will ensure it will get the full 4hour charge today and then let you know the results tomorrow morning.

    wow, an hour to drop it 20% sounds like more of a drop than my touchs. were you gaming, by any chance? or just using wifi?
  • juniperpansy Level 1 Level 1 (0 points)
    Okay I charged my battery up to 100%. I probably played games for 30min on it and then read an e-book for 90min. battery life was 60% before I went to bed. I put it in standby for 11 hours. After I woke up this morning the battery was completely dead. I guess I'll try turning off wifi tonight to see if it makes any difference...

    But is anyone else having this problem?

    I am glad i am not the only one...i went to bed with mine almost fully charged last night, read for 1/2 and hour on it...probably about 75% charged when i went to sleep and completely dead this morning...so frustrating...i never had this problem with my second generation one...

    I wonder if what we're all experiencing is the power of location based advertising? My previous 2 generation touch had great battery life till the IOS update that leaves wifi on even when in hibernation/sleep... Whatever we're calling it now.

    No.

    Source? Isn't location based advertising about knowing where your device is at all times.

    i've noticed that when when game center is running, the battery life is much shorter... might try turning that off...

    Here is what I found. There are still some apps out there that are simply not iOS4 tested and compliant. If you have one of these apps running on the tool bar, then it will indeed drain your battery. I pretty much know which ones aren't and so I just make sure those babies are closed before hitting the sleep wake button when going to bed. I've not found any significant battery drain doing this. However, when leaving some apps there that aren't iOS4 complaints, it sucked my battery down like a fish in water.

    I had this same issue on my iPhone 4, but I generally have gotten in the habit with it, to close down all the apps running and my battery life is great. Doing the same with the iPod touch 4 will generate the same results. Clearly there is something running that is draining the battery.

    Remember power and resource management (suspend mode) is only working on those apps that are iOS4 compliant (you'll see iOS4 tested) on the app description.

    My suggestion to those having this issue is just close out everything on your taskbar and see what happens to your battery life.

    If you continue to have problems, go into Settings>General>Reset>Reset Network Settings.

    Then re-enter your preferred network.

    There are several threads on here that indicate resetting network settings helps improve battery drain. I have the new iPod touch and my iPod battery was draining overnight. After I reset network settings, my battery drain is dramatically improved, especially in standby mode. Now my battery only drains about 10-15% overnight at the most, even with wifi still on. If I turn airplane mode on, results are even better.

    I don't know why this works, but it sure did in my case.

    Solid: I tried resetting network settings last night, but that made absolutely no difference for me.

    Looks like a lot of other people are having the same problem (4 pages worth)

    I am going to try turning on flight mode and closing all apps in the taskbar tonight and will report back tomorrow.
