    I just looked at www.apple.com/macbook and they are now advertising that the unchanged Plastic MacBook offers up to 7 hours battery life, down from the 10 hours they were advertising up to now.

    This probably means that the 2011 MacBook Pro 13" does indeed have the same battery life as the 2010...

    I don't know if I buy Apple's reasoning that their new tests are more accurate.

    If that's true, why hasn't the MacBook Air estimates changed?

    I think they shaved off 3 hours on battery life (most likely due to processor or chipset jump, or Thunderbolt), and needed a marketing line (read: a lie) to justify it.

    I would agree. Coconut Battery shows 5770 for my 2010 and 2011 MBP 13".

    Because the new tests started with the MacBook Air.

    True. The real question is why they didn't recalibrate the MacBook Pro and MacBook battery claims when the updated MacBook Air was released last October.

    Well, sure that makes sense.. but does that mean they've been advertising disingenuous numbers for MacBook Pros for 4 months now?

    Because it's apple advertising their own product, and the average user does not know/care how apple tested the battery life, and only cares about the number of hours.

    This may be true, but I have to think that the quads are using more juice too

    Yes and no. Tests change... that doesn't mean that manufacturer's need to go back and retest every configuration they ever released. Or even current ones.

    There is a very close analogy in the automobile industry. A few years ago, the Society of Automotive Engineer changed the test they used to determine an engine's horsepower. This resulted in cars having different horsepower numbers from one year to the next, even when nothing had changed.

    Does this mean that one engine had different output than another? No. They still made the exact same amount of power... just the testing methodology had changed. Were automakers being disingenuous advertising numbers gleaned under the old test? No - that test was the standard when that model was released, therefore using those results was OK.

    I'm more surprised that Apple updated the MacBook to reflect the new test than anything. But I guess it makes sense that everything on their website now adheres to the new standard...

    I can certainly see how people might consider this practice disingenuous, but I really don't think it is. It's more or less the norm when testing standards change...

    This was posted on computer shopper's website today regarding their review of the new 13"

    "The MacBook continued to trounce its competition in our battery life test. We ran our demanding DVD rundown test, where we loop a movie until the battery dies. At press time, the battery was set to die after about 7 hours and 30 minutes. (We'll update this time when our battery rundown has completed. The previous version of the 13-inch MacBook Pro lasted 7 hours, 28 minutes, so we expect that number to be accurate, since this version has the same battery.) This time beats the thin-and-light-category average by more than four hours, and no other similar notebook even comes close. Apple rates the battery life at 7 hours in its online-video-streaming rundown, so it's nice for once to see a battery last even longer than a maker touts."

    I think it is safe to say that battery life will be the same, but Apple is simply being more upfront about real life performance.
