For me i still think that facebook app is draining lots of battery.
Even they say they have fixed the issue
As it's all PUSH
Turn it off for one day have a try.

Well this is with these
settings

3G off
location service - ON ( this will not drain your battery if you don't use the apps )
notification - ON ( its just a beep to remind you it doesn't constant drain batt too)
Mail - Fetch - Manual
Facebook Push - OFF ( but manual checking > 20 times for updates and viewing alerts )
MSN - not sign in

been surfing and chcking for mail ( 3 accounts ) rather frequently >10 times
some gaming. completed all levels of angry bird lite.
light surfing .

if you cant boot up most probably you need to kick it out of it.
usually happens if you get error during your restore session using itunes.

tinyumbrella has that feature.
