Help Battery draining faster since 2.2?

[Zumi]

I went ahead and installed Froyo since I had heard that the battery life actually was better. I actually wasn't having issues with 2.1 batt life, but I wanted to see it for myself. Before when I would goto bed, I'd MAYBE lose 10% life overnight....but last night....I went from 70% to 40%!?


Anyone have any ideas what may have changed? I have it set to the battery profile that only turns off the 3G radio during the night hours after 15 mins of no usage.
