Microsoft and Intel recently demonstrated how Windows 7 stands to offer better battery life under certain usage scenarios than Vista, and they used a Lenovo ThinkPad T400s too.

Playing a DVD on two identical T400s’, the Windows 7 machine was drawing 15.6 watts while Vista bumped up to 20.5 watts. The benefit here will only be seen when you are actively using the machine, as Windows 7 have a “power coalescing” feature that lets one CPU core sleep as long as possible when it’s not needed.

Gizmodo also mentions that the next mobile chip from Intel will be able to execute two threads per core, improving the multi-tasking performance of both cores and possibly allowing for more situations when the 2nd core can be powered down.
