Low battery life on iPod touch after installing iOS 4

    The upgrade of my ipod touch 3rd gen to IOS4 was fine. Upgraded it to 4.1 a few days ago, since when the battery life is dire. It runs flat within 4 hours of going off charge. This is a new ipod bought in July, and it seems that the wifi is draining battery even when the touch is in sleep mode. Basic embedded OS programming error Apple. This is pathetic - are you going to be replacing my soon-to-be-wrecked battery free of charge?

    You've just convinced me to forget about buying an iPhone and get an Android phone instead.

    Ditto. I found the same with my 2G 32 Gb

    The prev OS actually did SHUT OFF wi-fi when in sleep mode (screen saver on - screen off). Then when I woke it up, wi-fi would come on ( confirm with wi-fi symbol - top-left of display & confirm with my network monitor on my Windows 7 PC).

    Now, iOS4 keeps wi-fi ON ALL THE TIME, even in sleep mode (screen blank).

    This is how the touch OS worked for the past 2 years as I always upgraded to the latest released OS, when notified by iTunes.

    Can't understand how Apple has it, then misses it - drops the ball - on the next OS update/release ????

    Have you guys seen this thread?

    Apparently the bug is even effecting the new gen-4 touch. I hate it for them, but this might actually be the catalyst need to get Apple to fix this problem.

    btw, for those claiming that resetting the network settings is a fix, it did NOT work for my gen-2 touch.

    The work-around of keeping notifications and push off does work for me as long as the touch is sitting on the home screen when it goes to sleep. Even leaving the music player up will trigger the battery drain.

    I have had the same problems (quick battery draining, slow operation, unable to synch) since "upgrading" to ios 4.0, 4.0.1 and 4.1 on my itouch 3rd gen 32 gb. I then reverted to ios 3.1.3 and all is back to normal. I used a detailed method to UPGRADE back to ios 3.1.3 as described in the October issue of MACLIFE, page 87 that I purchased from Barnes and Noble. Apple should have let us all go back to ios 3.1.3. All is well with my ipod touch now - at least i am running 3.1.3. It is faster, I am able to synch, and the battery discharging so quickly has stopped. Music does not skip as it did on ios 4.xx. Hope this helps others.

    Last night I received an email from Applecare.com asking me to give them details about the battery destruction and how to use the battery logging system - trouble was it was for an iphone and not an itouch. So Apple is aware of the many problems with ios4.xx even on the iphone. But why did it take them so long since mid July's release of ios 4.0? Why did they not adequately test their software systems before release?

    This will be the last Apple product I purchase - seems like Jobs needs to retire again. Whpen my t-mobile contract runs out i will go with a droid.

    Best to all - this monstrous thread has been interesting.

    Apple - you need to get your act together ASAP.

    I did the network reset as well, with no change. It went from fully charged at bedtime to DEAD by morning. For the record, I have push notifications disabled and no friends/no games in Game Centre, so nothing for it to be doing in the background.
    I read on another thread that closing open apps might help (anything open in your taskbar continues to run on OS4), so will give that a try now that I'm fully charged again today.
    Apple: PLEASE implement an OS fix to halt background activity while the display is off. Please?

    I don't think it is any "background activity" per se, as much as it is the wi-fi being on - "continuously".

    When the touch goes to screen-save (screen blanks) the wi-fi should SHUT OFF, to save power.

    Now I have used my 2G touch consistently for the past 2 years, and that is how it used to work, because a full charge lasted nearly 7 days - 95% of the time, it was in screen save mode - never powered it down - didn't need to.

    It's like if a cell phone kept transmitting, even after you hung up ...

    Did you also install 4.1? When I reset my network settings on iOS 4.0.2, I didn't see any improvement either. It was only after installing the iOS 4.1 update that my Touch's battery issue was solved.

    Also, under the old 4.x firmware, if you are using mail push notifications (or calendar ones), you will still have battery drain even if you have app notifications off.

    Yes, this battery issue only started to manifest itself when I upgraded from OS4.0 to OS4.1. Prior to 4.1, my battery would last for days (with push notifications off) if I didn't use it much.

    I have a 3rd gen 16 gig Ipod touch. love it. But when I installed OS4 battery life dropped to overnight drain. It was suggested to turn off all the "push" functions, which I did and YES! Battery back to normal.

    Now I was a good boy and installed OS 4.1 - same battery problem. Overnight drain when it is turned off. I have turned off all of the options on every program that I can find and the problem persists.

    I am getting the impression from comments here that it may be WiFi causing the problem?

    Hello Apple! Are you there?? I refuse to turn off WiFi every time I turn off the Ipod. If there is no solution to this problem I will revert to my trusty Palm or something else and never buy another Ipod.

    No Apple is not necessarily here. I strongly recommend you report your problem to Apple by calling AppleCare or filing a bug report. That would be a constructive use of your time anyway.

    tw_yogi,
    The irritating thing is that this bug has been around for more than two months already. Apple has made 2-3 iOS4 updates since, but this issue is simply being ignored.
    And no: resetting the network settings does not change anything (obviously).

    Why do you say "obviously"? Simply resetting the network settings made a dramatic improvement in the fast draining battery of my G4 iPod touch, for whatever reason. It doesn't help everyone, but there are those of us who have been helped by this simple tip.

    I bought my first generation 32 GB iPod Touch in the summer of 2008. My battery lasted for something like 5 days if I used my iPod a few times a day checking email (say 2 hours/day).

    Now my battery life dropped to less than 24 hours after upgrading the firmware to version 3.1.3. After 24 hours the battery is completely dead! Not good for a battery to go completely empty. In those 24 hours I use my iPod for about 1 hour to listen to music. I have tried many things to fix this w/o success. Even visited an Apple store, the "genius" pretended that there is no battery problem associated with firmware upgrades. Downloaded and installed firmware version 3.1.2, same problem. Read thru many messages posted on this forum and tried many things suggested here.

    I am most disappointed in Apple because: a) Apple does not acknowledge the problem, and b) there is still no solution in sight.

    I am not sure what to do. It is very sad that a firmware upgrade broke my iPod and there is no sign that Apple is willing to help fix (or even acknowledge) the problem.

    I put my iPod Touch 32GB in airplane mode once it was fully charged this morning, and now, 12 hours later, the battery is still showing fully charged (I used it to play a game for about 30 minutes). I definitely onboard with the suggested cause being continuous wifi activity after seeing this dramatic turnaround. Yesterday, with wifi on, it was dead by 6pm under otherwise same conditions.

    Of course, the extra steps to turn wifi on and off really dampen my prior love for this device.

    It breaks my heart reading this thread. As an avid Apple fan over the years the iOS4 upgrade also broke my 2G ipod touch (battery drain). I reverted back to 3.1 and all is now well again.

    How difficult is it for Apple to add a Sleep Wifi mode to iOS? At least we have the OPTION of turning off wifi (and so not using multi-tasking). Seems a good solution?

    I was going to buy a 4G Ipod touch, but not until this is resolved will I spend my hard earned cash! Sorry Apple, not this time!
