I do check. Since I've been on 4.0.3, its been Android OS hogging all the battery. On stock 4.0.2 it was always the screen killing it. I haven't set any profiles and have been using default SetCPU voltages. I just now switched my SetCPU voltages, so we'll see if that makes a difference.DEFINITELY NOT!!! I'm averaging over 24hrs of battery life (Extended battery) with normal everyday use. I'm absolutely loving it. Every time I flash a new version i have done a full charge then used the app "Battery Calibration" (Free on market) to clear the old battery stats. Then from 100% run the phone to 0% and it turns off (at least 24hrs later) and then turn it back on and charge it back up to 100%. I have been having great battery life with both 2.1 but especially 2.2. Also i'm using setCPU to underclock to 180mHz while screen is off. If you are still having bad battery life it is probably an app or something screwing it up. I call operator error on this one and maybe check battery usage from system settings and see what's sucking all your battery juice.
I'm still having other issues with 2.2 though. I just realized that GMail isn't syncing; I have to manually sync it. Reception seems a bit worse than 4.0.2 as I previously mentioned. And the "bars" no longer turn Blue. I will still have data, but it looks like I don't. Camera is no longer zero shutter lag lol. There are a few other things I'm forgetting too. I'm going to have to flash 2.3 and hope these issues are fixed, or else I think I'm going to try a 4.0.2 ROM.
