Poor battery life since OS4....

[davek0974]

Hi all,
Has there been any development on the issue of poor battery life since installing the os4 upgrade?

I have been trying the apple forum but it seems they Re ignoring the issue.

Thanks
Dave

Edit: Oops, I put up the wrong reply in this thread.

What generation iPod touch do you have? Did you upgrade to iOS 4.1 or 4.2?

[davek0974]

It's currently on 4.2.1

It's fine if I run in airplane mode but that's not a fix it's a botchy workaround. It was fine before the big "4" upgrade since then battery life pretty much sucks, its a widely known fault which is why I can't believe apple is doing / saying nothing.

It seems the airport/wifi in the new os is configured wrongly for iPods but not for iPhones which appear ok as far as I know (I dont have one)

I would downgrade to os 3... But it seems it's not possible.

Any news?..

I guess you are using a 3G iPod touch? The generation of the iPod is actually important as it determines if you are running apps in the background. iOS 4.x introduced a new feature allow apps to update information, via wi-fi, while the iPod is in sleep mode. This consumes computing cycles and power. Either closing out all of the app or turning off the wi-fi antenna will solve the problem. This is not a bug but rather a new feature. Current generation devices (such as the 4G iPod touch, iPad, and iPhone 4) normally don't have any battery life issues with iOS 4.x. Older generation iPods seem to have most of the battery life issues with this new feature.

It's a 2g touch, yes turning off wifi fixes it but that's not a fix it's a bodge. They should just let us downgrade again or put out a bug-fix patch. 2g iPods can't multitask anyway so there is no benefit of os4 just a lot of problems.

You are wrong buddy. My iPod turns off the Wifi seconds after putting it to sleep when running on battery which is why I have to set it to never lock the screen because I run streaming music apps that turn off the screen every-time which means that after a few minutes the music stops streaming. Yes this really kills the battery life but I have no choice.

No, I am not wrong. Look at previous posts going all the way back to when iOS 4.1 was first released. I can even run Pandora now, hit the sleep button, and it will continue playing audio that it is accessing via wi-fi on my 4G iPod touch. You can also read the change log that Apple released going from iPhone OS 3.x.x to iOS 4.1, the ability for apps to update content (via wi-fi) when the iPod is in sleep mode is clearly listed. So I guess me, the admins here, everyone experiencing battery drain issues, and Apple are all wrong.
