Just in case you didn't realize, Gingerbread leaves Wi-Fi on if I am not mistaken. Not sure if the Power Control widget shows it being on, but double check under Settings.
Also, go to Settings, Battery & Data Manager, and then Battery Mode. Select Maximum Battery Saver, which should help out lots (if apps honor OS setting)
GB really does have a lot to save on battery, so it is likely something you installed/restored. Each program likely has its own settings to Refresh/Sync, so double check 'em all!
I'd also throw out there to reset battery statistics in bootloader.
