Microsoft: Windows 7 can offer better battery life

Upgrading a newer machine from Windows Vista to Windows 7 might mean that you get to see the last few minutes of that DVD on a long flight.

At a demo on Tuesday, Microsoft showed two identical laptops playing the same DVD, with the Windows 7-equipped notebook getting 20 percent better battery life than one running Windows Vista. In general, users can expect newer systems running Windows 7 to offer 10 percent to 20 percent better battery improvement when watching a DVD.

"We're achieving a very significant amount of battery savings," said Microsoft principal program manager Ruston Panabaker.

Microsoft and Intel declined to say just how much overall battery life improvement Windows 7 might offer as compared to Vista, saying there are too many factors that can influence such results.

"I don't want to state a number," Panabaker said at the event, which was organized by Intel and Microsoft.
