Improvements in both the Microsoft Windows 7 operating system and Intel's upcoming Westmere processors will result in significant increases in battery life, executives said in a press conference on Tuesday.
In a demonstration of two identically configured ThinkPads T400s, Intel and Microsoft claimed that a Windows XP SP2 machine consumed on average 20.2 watts, while the Windows 7 machine consumed 15.4 watts. That translated to about 1.4 hours of additional battery life, executives said.
