I'm using BB v0.4, Chevys 1GHZ ulv kernel, and smoked glass theme for v0.4 too. I noticed yesterday that I was also having terrible battery life, and I think its from the themed genie app. Check to see if the genie's weather says it can't find location. I think it maybe a GPS bug and I saw a fix in Chevy's forum, but haven't tried it. I took off the widget and it seems better today.
