so, I updated to IOS4 on my itouch and ever since my battery takes a dump quickly. And yes, I did disable all the crap like push and location etc (even though it was enabled on my previous OS without issue!). I ensure that the multitask bar is clear and still it takes a dump. I could leave it connected to the wireless and casually browse all day but now I have to keep it plugged into a wall, sometimes I wake up in the morning with it completely dead... anyone else have the same issue? or a fix? I didnt have to turn off wireless everytime i set it down before the upgrade.
