By the end of a work day, my battery is usually around 50-60%. On weekends I don't recharge it at all, including this last 3-day weekend. It was at 43% Monday night. I never turn it off, I check it often as I get a lot of email.
I am running Dynamic Kat, just upgraded to 3.0. I use no apps to extend battery life. I turn off my wifi when I go to bed, turn it back on when I get up. Note that I NEVER turn data on.
