With the extended Moto battery, rooted, stock 2.2.340 all bloat froze via Titanium Back Up, screen brightness at an acceptable 20% or so, 30% wifi/70% 3G. I probably could have gotten a few more hours as it was at 12% when I plugged it in. I am not a heavy user. 10-15 minute talk per day, 20-50 texts per day, 20 minutes of Market, 30-60 minutes of internet per day. I never got this much life with any rom. Just thought I would share that.
