[TurboFool]

I'll just comment that my battery life, pre-extended battery, was extremely unstable, with one day to the next providing completely different results (I could get home at the end of the day with 70% left or 20% left with no tangible differences in my usage), and I also noticed that between flashes and hard resets I could get completely different experiences with the exact same ROM. You may wish to consider just a hard reset and see what difference that makes. It makes little sense, but it's something I've experienced.
