That's definitely weird.  I don't get 10 days between charges, but then 
my N800 is never idle for 10 days at a time.  I commonly run 3 days 
between charges, though, and I'm a fairly active user.

I don't do this.  If you don't get a more helpful response, I would run 
with a stock fs and no applications installed for a day (no fun, but an 
important troubleshooting step if you're not sure where the problem 
lies).  If you still have low standby life in offline/screenlocked mode 
then you definitely have hardware issues.  If not, then you can start 
introducing variables in a controlled way until you pin down the rogue 
config/app that's killing your battery life.  Please report back so 
others can learn as well.
