A a recent press demo, Microsoft principal program manager Ruston Panabaker showed how Windows 7 computers have better battery life than their older Vista counterparts. In general, the new OS will provide anywhere from 10 to 20 percent better battery improvement when watching a DVD. For the demonstration, two identical laptops playing the same DVD were compared, one running Windows Vista and the other running Windows 7. The Windows 7 PC lasted 20% longer.
These improvements have been made possible through joint efforts from both Microsoft and Intel who have worked together to bring better performance to the Windows 7 OS in areas like virtualization, power management, and performance. Also demonstrated was a PC that was able to boot up in 11 seconds. Although it’s important to remember that boot speed in the real world will be determined by a number of factors including hardware, installed applications, and system settings.
