New MacBooks list 'reduced' battery life [U]
(Updated with perspective) Apple's new MacBook systems technically list lower battery life than the previous generation, official specifications show. setteB.IT notes that despite the fact that the computers use Intel's new 45nm Penryn technlogy, which should be more power-efficient, each of the new machines "loses" an hour or more of operating time. The reduction in battery life is actually an illusion however, as Apple did not previously incorporate wireless functions into its estimates.
The new basic MacBook operates at 55W, for instance, but under Apple's revised projections falls to a maximum of 4.5 hours versus six. The 15.4-inch version of the MacBook Pro is rated at 60W, and suffers the least, shrinking from six hours to five. The 17-inch Pro is a 68W system, and drops from 5.75 hours of use to 4.5.
