Apple "After an unusually long wait, Apple has finally released updated models of its MacBook Pro line of notebooks. The 15" and 17" models offer the latest Core i5 and i7 processors, though the 13" model still uses a Core 2 Duo processor. But new processors aren't the only improvement; Apple has also seen fit to increase the base RAM configuration to 4GB on all models and bump the hard drive and SSD options. And Apple claims battery life has been improved, with some models now going as long as 10 hours without plugging in."

RE: Battery

Only the Core 2 Duo-equipped 13" MBP is advertised with 10 hour battery life. (The previous model had 7 hours advertised). The Core i5 and i7 15"/17" MBPs are advertised with 8-9 hours.

Still, why does this seem unlikely? Apple is using the mobile versions of the Core i5 and i7, which have a TDP of 35W in the systems they are shipping. This is the same TDP as the higher-clocked Core 2 Duos in the previous MBP 15"/17". Increased battery life is the combination of increased power savings from the new CPU, the CPU-integrated memory and PCI-e controllers, the CPU-integrated GPU, and probably a larger battery since more is integrated onto the CPU.
