Does OS effective battery run time/life?

Question

I really do not have a preference to which OS that I use, either XP Pro or Vista Business (although have never used Vista before) but I am wondering if using one verse the other would help increase and stretch the battery life.  If all things being equal as far as functions, radios turned on, screen brightness and such, will one give me longer run times than the other?
I have read a few entries and there seems to be more updates, revisions and features are being developed and put into Lenovo's management systems for Vista, so I am wondering if perhaps that would have any difference as well.
One more thing, has there been any updates/upgrades since Feb or March that would make a difference in the run time of the battery life with either Vista, XP or any of the Lenovo management systems?  I ask because I read the review at notebookreview and I was shocked that they only got about 3 1/2 to 4 hours of use from the X300 and the T400 is getting over 6 1/2 hours and both machines are using 6 cell batteries.

Hello DanMgy,
Vista out of the box and without tweaks like disabling aero or the sidebar may consume more power,
than an normal XP.
But Vista will give you more options to safe power, and a well tweaked Vista, seems more effective
than a normal XP. But in this case, it will problably having the look, as good old XP.
