What did iOS4 do to battery life of my iPod touch 2nd gen?

I upgraded my 2nd gen iPod touch to iOS 4 without incident. Upgrade went fine, everything seemed to work post-upgrade.

But since the upgrade, the battery is being drained at an alarming rate. The iPod touch sat in a cupboard for two days, starting with full charged, and with no use it is now down to absolutely no battery - the battery icon is at the bottom of red with a little lightning bolt symbol. I've actually never seen the battery so low. This has happened twice since I upgraded last week. What is going on?

    i have the same problem also.
    normally it can lasts me up to 1 week provided that i only listen to the music in the morning while travelling to school. now, only 2 days has passed and the battery is flat!

    I initially found that my Ipod Touch 2G was also suffering from excessive battery drain on iOS4 but since I turned Airplane Mode on it has been just as good as it always was. Give it a try. Oddly enough you can still have your wifi on even in airplane mode.

    I noticed that the upgrade set my 'Locations Services' to on - so perhaps it's getting 'pushed' stuff (and thus being 'on' all the time)?

    My iPod 8Gb has the same symptoms since I upgraded to iOS4, the battery would normally last so well that it only needed topping up every few days. Now the iPod loses 30% overnight and can lose another 50% during the day, even when not being used. It is as bad as a Windows Mobile device that needs charging every day.

    Turning airplane mode on stopped the wifi from working, so that is not a solution to the problem

    Russcolli is right about turning on Airplane mode and then turning on the WiFi. Since I did this the battery power has returned to normal and the wifi connects automatically when needed.

    I am another iPod touch user with the same problem. The rapid battery drain seems random. Some nights the touch lasts fine, and on other nights the battery is depleted to 20%. Sometimes a drain of 40% occurs over 3 hours even though the touch is not being used. Charging after such an incident requires only a relatively short time to full charge. I concur with others that part of the problem may be incorrect reading of the true battery level.

    Add me to the list as well on this issue. I use my Ipod Touch to work out and can normally get several workouts in before actually having to recharge it. The other day I went to work out turned on the Ipod and the battery was red, this was after not using it for a day.

    I may try doing a complete restore, airplane mode does kill my wi-fi, so who knows.

    Edit: did not notice that you have to turn wifi on after turning airplane mode on will try this, although you would think having another mode on would drain the battery faster.

    I have just same problem.

    Sure isn't related with the amount of work we do with iPod (Wi-Fi on, Push on, etc.) but with new iOS4.

    *With this new firmware battery is drained really quickly but I've also realised that iPod warms up* with normal applications (not CPU intensive ones), back-bottom becomes almost hot to touch. Sure this warming is a clue for finding issue with battery drain.

    *Does anybody know how to report this problem to Apple support officially, so they can develop a patch for new version of iOS4?*

    Yeah, apple's been really screwing our device. I heard that if it had wallpapers behind the icons, it still would run at good speeds, but back to the battery: I would recommend putting airplane mode on, and turning wifi on. I charge mine every night, so this isn't much of a problem.

    I have the same problem.
    I was really surprised after updating to iOS4 and my battery was totally drained the morning after. It's like if some process got stuck in a loop and drained the battery for no reason. I made a clean install hoping that would solve the problem but it does not seem to help at all. I hope Apple is aware of this problem and is planing to do something about it because it wasn't this bad before.

    I will try the solution above to turn on the Air-plane mode and see how the device works over a few days.

    But really, Apple should do something about this.

    Hey Apple? Reading the forums? Knowledge this problem and fix it already!

    It's kinda funny that you can put the device in Airplane mode but are still able to turn on the WiFi :P

    I have the same problems. The only way I can get the battery to last any length of time is to turn off everything in settings. I find now that I hardly use my I-Touch and when I do want to use (maybe once a day) the battery is . . . dead. I was just on the verge of buying an IPad and am so thankful I didn't waste that amount of money as I understand they have the same problem(s). This is all so Microsoft!
