CM7 is a total battery leech for me on the Blaze. I get unreal battery life from:
2.2 - JellyBean
2.3 - SuperAOSP 8.6
I'm keeping a log about my experience with the Cincinnati Bell Blaze on my blog (there's also a file to dl with both roms and sutlr), but evidently can't give a link as a first post. PM me and I'll send it to you.
