Help Battery Life Issues With Froyo 2.2

3 hours ago i manually updated to froyo 2.2 and am so far estatic about it, but have one serious issue.

battery life has gone down extremely quick and is really disappointing. Just three hours after updating battery is dead, went down to less than 5% and i had to charge it.

i have a task killer and at first just manually kept killing, and then set auto kill to aggressive. Made the brightness all the way down and screen timeout to 15 seconds and still dies so fast.

has anyone had this problem?? I really cant afford to have to keep charging every 3 hours.
 
My Evo's battery life was still terrible after the update to 2.2, but after a few app updates, it's been great..

I also took care to make sure that every auto-updating app was set to 4 hours, or manual update. I also keep 4G turned off unless I'm in one spot where it's working.
I've had it off charge since 8 AM today, and it's down to 50% at 10 PM, and this is with fairly heavy use.
I'm not sure what happened, but now the battery graph remains flat during off periods. I have spans up 5 hours or more where it didn't drop at all.

One thing I recalled doing was going into the settings menu, applications, Running, and stopped everything I didn't use, or felt should not be running. (Most of these have started again). Perhaps something was stuck running, and has now been silenced?

I can only speak for myself but after upgrading to Froyo last night, my battery life has been greatly improved. I'm using a moto droid, I charged it last night, unplugged around 12am and now it's almost 8:00pm and I'm still at 80%. I'm not on my phone all day or anything but I'd say it went through moderate use. Usually when I get home from work I'm down to about 50%, but not today. Needless to say I'm very excited about finally having froyo!
