Mac OS X 10.5.7 enhances battery duration?

According to what was reported by Wired’s Gadget Lab, the latest Mac OS X update, the 10.5.7, would have brought an enhancement to the energy saving management for the notebooks. In reality, the test wasn’t done on Apple manufactured computers, but on netbooks in which the Mac OS X has been installed.

Considering this rumor true, it could have been for two reasons: either the Mac OS X truly features energy savings optimization, or it could have also been due to the support for Atom processors, that usually equip netbooks from Dell, MSI and others.

In particular, it seems that the new update brought an enhancement of 33% on the battery duration of a MSI netbook, bringing the duration to more than five hours (From the previous 3 hours and 45 minutes).

We’ll be tuned for more information on the matter and perhaps some mentioning on how the update would work on true Mac computers.
