Anyone else having this problem after 4.0 update?

Question

I just updated my Ipod Touch to the latest version, 4.0 software, as I'm sure most of you have.
I'm wondering if anyone else is having an issue with the battery draining very very quickly? I have changed nothing on my Itouch, except for the update. All my push notifications are off and I have double checked that. I haven't downloaded any new apps, still using the same ones I always use. My internet connection is still the same as I have checked that too.
My battery is running down so quickly without using any apps that I have had to charge it twice in the last 8 or so hours. Where as before the update, I used to charge is either once a day or everyone few days, depending on what I did with it.
So if anyone else is experiencing this, please let me know. Or if you know how to fix this problem I would appreciate some advice on that too!

Answer 1

I am having this same exact issue with my 2nd generation touch. I saw on some other topics that having wifi on all the time is the problem. I tried turning it off, but it didn't help. You could try that though and see if it helps. But on my iPod, even in Airplane Mode, it drains the battery like a Hummer wastes gas. Incidentally, if turning off wifi works for you, great! Except to me that pretty much defeats the whole purpose of having a touch. Might as well have a nano or Classic. Having to turn of wifi each time you want to check email or use an app that requires wifi is silly. wifi should simply go off when you put the iPod to sleep. But here's the thing. Even with the old version of the software, I could listen to Pandora for 3-4 hours a day (of course requires wifi) and I wouldn't need to charge the iPod but once every couple of days. Now, I can't go 8 hours without the thing draining to 20% warning. To me that says that something else is running the background and that wifi isn't the only problem.
