Vista to negatively impact battery life?
News.com reports that Windows
Vista negatively affects notebook battery life
according to tests
from an anonymous hardware manufacturer. In its average power mode, the
upcoming Microsoft operating system reportedly results in "noticeably
lower battery life" than Windows XP. Naturally, the new GPU-accelerated
Aero user interface is said to be the
main culprit. No actual numbers showing
differences in battery life are available, but Microsoft is reported to
have acknowledged the problem. The company told CNET it is working with
notebook manufacturers to "ensure that systems are better able to handle
the change," and that it hopes to "close the gap" before Vista's
expected release in January 2007.
Of course, Apple has already shown that good battery life is quite
possible even with a fancy user interface. In Ars Technica's review of
the new MacBook, the machine yielded slightly over four hours of
battery life in a "medium usage" test. Since MacOS X also sports a
GPU-accelerated user interface and the MacBook's specifications are
quite similar to that of PC notebooks, it would be surprising if equivalent
Vista-powered machines turned out to have significantly worse battery life.
