Are any iPod touch 4G users experiencing battery declines with iOS 5?

Personally, I'm not seeing any battery life declines under iOS 5. Or they are not that noticeable. My battery life, for most part, is the same as it was under iOS 4. Actually the battery life seems to be slightly better. Maybe it is just some bugs with the GM.

I'm curious as the battery issues seems to only affect iPhone 3GS, 4, 4S users. I'm also curious to see whether iPad, original and 2, users are seeing battery life declines under iOS 5?
