4.0 Battery Drain?

Same here
I updated my 3GS to 4.0 GM and have really bad battery life. The first full charge got me almost 7 hours of standby with about an hour of talk and wifi usage. With this type of usage on 3.x, i could have easily gone a couple of days between charges. I set my only email address that was using fetch to manual and I left three addresses as push. This improved things a little bit. I took the phone off the charger and left it sitting on standby for about 5.5 hours. This drained my battery to about 65%. Still, this is not acceptable. I have a 12 hour road trip coming up in less than a week and don't (yet) have a car charger.
If anyone has any suggestions, I'd greatly appreciate them.

Download and reinstall and set up as a new phone- do not restore from backup. Alos try resetting network settings
Yeah. I did reset network settings. I was kind of hoping to not set up as new phone. Will I lose my app data by doing this, such as game states and things like that?
I can add credibility to this. I upgraded to iOS 4 GM yesterday and was just telling my wife that I think my battery on my 3Gs is wearing out all of a sudden because I got really bad battery life today. It didn't occur to me that it could be iOS 4 until I read this thread - hence it is likely not placebo effect.
I'm not going to worry about it since I'll be getting the new phone, but I may clean install before selling this one.

Maybe it't because the 3rd Party Apps are not setup for Multi-Tasking yet. I noticed they remain in the bottom Apps running bar. You can close them manually by holding down on their icon. Not sure if this will help. I did notice my battery drain faster today than normal but I also think they were working on towers in my area and my phone was working harder for signal than usual.

This makes perfect sense! Improper multitasking would definitely kill battery.

Umm there is no multitasking yet. And apps in the subdock are *not* running in the background.
I saw a 20-30% decrease today after installing the GM yesterday.

Sorry to quote my own post; however, I have seen some results after disabling notifications. Since my last post, about three hours ago, I disabled all notifications and left the phone on standby. Since then, I remained at 54% battery power. So, it might be a particular app or just notifications in general that aren't playing nicely with OS4 GM. I'll add any updates if the situation changes or I can determine that something in particular is the culprit.
