W7 X64 on Netbook decrease battery life?

Toshiba Mini nb305-n410wh netbook

Specs: Windows 7
So I just clean installed Windows 7 ultimate
64-bit on my new toshiba nb305 (which has a
N450 processor that supports 64-bit). I
noticed that the battery life has been cut
almost in half. When I first turned on with W7
starter the battery life was around 10 hours but
now its around 6 hours. Should I expect it to
be so low? Or should I switch to W7 ultimate
32-bit. I did notice the computer is slightly
faster (though I did put 2GB in as well).

Read THIS article by Laptop Magazine. Quoted:

The biggest surprise was the loss of battery life. When we ran our standard battery test on the Toshiba NB205 under Windows 7, it lost more than 3 hours. Under XP it got an amazing 9 hours and 24 minutes, but with Windows 7 it only lasted for 6 hours and 15 minutes. Installing new Win 7 drivers from Toshiba only resulted in an extra half hour or so (6:53). We also noticed a bit of a drop-off with another netbook we tested: the MSI U123. This time it was less dramatic: 8:14 in XP vs. 7:41 in Win 7

Changing to Windows 7 32-bit will not produce any difference per se. It is Windows 7 itself.

Also check your power settings, the standard installation of W7 is probably NOT optimized for your notebook like the factory installation was. Look especially for the time before the hard drive powers down, as well as the same for the monitor, and for the system to go into Hibernate. Also make sure that nothing launches when windows starts except your AV program.

You have to be a little bit crazy to keep you from going insane.
