Surprisingly, the nc8430 laptop's battery lasted longer with Vista running than it did with XP running. And that was without tweaking Vista's power settings to extend the battery life.
During my test, I ran the laptop at full load -- complete with a sample picture menu, 10 Internet Explorer windows open and a DVD of Endless Summer playing. The battery lasted 3 hours and 5 minutes with Vista, compared to just 2 hours and 35 minutes with Windows XP.
"That said, if you run Vista in battery-optimized mode (using non-3D interface), we would not expect the battery life to be significantly different from XP in that scenario."
"We've done extensive testing and we haven't seen [shortened battery life]," said Gateway spokeswoman Kelly Odle. "While it is true that Vista has higher system requirements than XP, it also has more sophisticated mechanisms to allow for power savings."

From my personal experience however, I haven't seen any distinct difference in my notebook or Tablet PC battery run-times using Vista over XP.

We tested the battery life of a Toshiba Tecra M6 running alternately WinVista Beta 2 and WinXP and found the scores to be roughly comparable.
