iOS 4 Causing iPod Touch Battery Problems

iPod Touch owners are flocking to the Apple support forums after installing the latest update, iOS 4. For users who bought the more recent third generation device, the upgrade provides a robust lineup of new features including multistasking, folders, home screen wallpaper, Bluetooth keyboard support, and more. For second-generation owners, the update isn't quite as generous, leaving out the wallpaper, keyboard, data protection, and multitasking support.

Hey, at least it gets iBooks.

In a topic called Low battery life on iPod touch after installing iOS 4, users are stating the obvious: iOS 4 is consuming tons of battery store. "My iPod Touch (2nd gen) is completely charged when I go to bed, but when I wake up in the morning it is completely drained and non-responsive," reads one complaint. "This never happened under pre-iOS 4 releases."

One third generation owner echoed the same complaint. "Absolutely the same with my 3rd gen iPod. Go to sleep with nearly full battery, wake up with a nearly empty one," said DrWig. "This update has crippled my iPod. I really hope the restore feature works to get me back to os3..... My iPod clearly isn't going into standby like it used to."

As of this writing, there are thirteen pages just in that particular topic alone. Other topics on the Apple Support forum include iOS 4 seems completely to have wiped out my 3G iPod Touch and iOS 4 Killed my iPod 2G WiFi. As for the battery drain, it's speculated that multitasking is eating away at the battery, however that's not possible on the second generation device. The Wi-Fi connection itself may be the issue, as it now stays connected when the device goes into sleep mode.

As an owner of the second generation version, I just installed the new OS last night. It was fully charged when I finally crawled into bed, and twelve hours later--with Wi-Fi, push notifications, and location services still on--the battery looks to have retained most of its charge. So far I haven't seen any problems, however I was forced to revert the device back to its factory settings prior to the upgrade because the initial backup process was taking more than three or four hours. I didn't have this problem with the last OS update.

So what exactly is killing the battery on these devices after the update? Some suggest that Wi-Fi should be kept off until needed. It may have something to do with a bug in the OS, or some kind of corruption residing on the device prior to the upgrade. So far Apple has not commented on the problem.

UPDATE: I can now officially confirm the battery issue. As previously mentioned, the battery consumption seemed normal twelve hours after the iPod Touch 2G was updated and charged. However, just minutes ago, I tried to turn it on and it was completely dead. I haven't used it since iOS 4 was installed (outside updating apps and downloading iBooks, but that was within the initial 12 hours). Typically the charge will have a duration of (seemingly) weeks when left unused--I've never seen the device lose a full charge after sitting idle for less than two days.

    I did have the same feeling on my iPhone 3gs. I haven't measured it, but the battery subjectively seems to not last as long.

    johnh2005icomplainer: Oh noes my iPod's does not works as it used to, z batteries drains faster.Steve Jobs: Your iDevice just needs a new extended battery. We just happen to sell then now for $39.95 plus you have to pay to ship your device to us, wait three to 13 weeks, pay return shipping and a $99.99 service fee and your iDevice will be as intended.iComplainer: Thank you lord and master Jobs.You see you only get thumbed up if it is a funny mocking... this was not. better luck next time.

    furthermore I am baffled by the whole situation with apple. A few days ago we had a rage of articles which basically said: apple sucks at everything, and I thought this could not be worsened on. Today, the news has proven me wrong.

  • A fee things drain your battery faster, the biggest being persistent wifi that keeps the wifi on at all time. That us the biggest drain on the battery. I turn off the wifi on my iPod 3G and it lasts almost like it used go overnight. Folders and wallpaper also seem to eat up battery life for some reason. I used to have two pages of folders and got it down to one and noticed that my battery life got longer with fewer folders spread across fewer pages. To be honest I was expecting a shortened battery life. It happened in the is 3 upgrade with push notifications. It wasn't as drastic but it was still there

  • I have this problem on my 3g Ipod Touch 8gb. The solution: TURN OFF YOUR WI-FI when you are not using it. iOS4 does not automaticallly shut off your Wi-Fi, even when you power off. It's pretty lame, hopefully they fix this soon with an update.

    A: Who the hell keeps wi-fi (and bluetooth) on if they aren't using it? They're notorious for draining batteries!

    B: Dude, it's iPhone

    A: Oh...
