    This confirms what I suspected—the new MacBook Pro battery has a lower capacity than the old one. About 16 percent less to be specific. The old battery was rated at 5600mAh/60Wh, but the new ones are rated at 4700mAh/50Wh. This perfectly explains why you now need to use the integrated Nvidia GeForce 9400M on the new Pro to get the same five-hour (rated, not real world) battery life as you did with the discrete 8600M GT on the previous-gen Pro, despite its use of more energy-efficient DDR3 memory (which would negate drops from the faster FSB) and the same processor clock speeds.

    Damn... Apple is losing it. The entire refresh has been a big step backwards for the MBP line. WTH?

    I was wondering when someone would check the battery capacity. I was going to do it myself.

    I suspect all the clearance/refurb old model MBPs will fly out of Apple's warehouses now. I'm pretty glad that I was able to get one for such a stealing price. :)

    It shouldn't matter if capacity decreased if battery life is the same.

    Apple did say using the 9600M yields about 4 hours, which is technically in spec with the battery life on the 8600M MBPs.
