Last week Anandtech tested browsers for battery life, and this week they've published an article in which they compared the battery life of Windows and Ubuntu on an AMD and Intel based laptop. You can check it out over here. Things don't look too good for Ubuntu on laptops, the site found this operating system is consistently the worst performer of the tested operating systems.
The average increase in battery life over all of the tests we performed so far is 33%, and that's taking into account the fact that Ubuntu closes the gap quite a bit between the two platforms. Throw out that Ubuntu result (only 13% in Intel's favor) and the average battery life lead increases to 37%. Why should we throw out Ubuntu? If you took the time to read this article, you already know that Ubuntu is consistently the worst battery life of the tested operating systems. As much as people like to complain about Windows, manufactures have worked a lot more on optimizing battery life performance for Microsoft's OSes. Then again, as we repeatedly mention in laptop reviews, Apple's OS X is in a league of its own when it comes to battery life. Not surprisingly, having full control over your operating system and hardware can give you a real advantage when it comes to laptop mobility.
