I don't know about you guys, but today i took it off the charger at 9am with 100% battery, kept mobile internet connected and always on. Constantly used text messaging, google talk and voice. Made 6 or 7 calls, checked my email and opened up a few attachments. All the while gmail calendar, contacts, and gmail auto sync is on as well as twitter sync and auto weather update (1hr). Probably missing some other things but my current battery now (its 10:30pm, so 13 1/2 hours later) is 44%

I have autokiller set to automatic/default setting. I shut the screen off when i'm not using the phone. My display (battery hog) is set to auto brightness. I never turn on gps unless its plugged into my car charger (didn't use gps today). WiFi and bluetooth keep always off.

Check currently running background apps by holding down the home button... You can shut these apps down by pressing menu>settings>applications>running services... Tap any currently running application that you don't need, to stop it. Some people have MANY MANY apps running and have no idea.

Good luck
