Somebody should tell Doug “netbook” Aamoth that Windows 7 seems to be a battery hog. The fine folks at Laptop magazine have put three different netbooks to the test, determining their respective battery life under both Windows XP and Windows 7. Looks like Windows XP is the winner.

The netbooks test include the Toshiba mini NB205, ASUS Eee PC 1008HA, and HP Mini 311. They were all subjected to Laptop’s standardized test, which consist of Web browsing over Wi-Fi. You know, like you do in real life. Any and all “power-saving” features were turned off, so as not to give one netbook an unfair advantage over another.

The winner? It seems Windows XP is more energy efficient than Windows 7, with the older operating system lasting, on average, 47 minutes longer than the new kid on the block.

Of course, now you’d have to give up all the improvements that are present in Windows 7. Then again, you are using a netbook, so you’re already walking in with a loss.
