    New Macbook Pro 17" battery capacity is Down by 30.7% !!!!

    When you look into the system properties

    you see the Complete Charge Capacity (mAh) of :

    12691 mAh in the mid-2010 Macbook Pro 17" Core i7 2.66GHz
    8653 mAh in the early-2011 Macbook Pro 17" Core i7 2.3GHz Quadcore

    Check on your systems and compare with older version I am sure you will find the same kind of values.

    That's -30.7% on battery capacity so going from 10 hours to 7 hours makes sense.

    I just found out about that opening my new MBP Quadcore tonight and I am really upset : how can they reduce battery capacity while increasing horsepower !! It doesn't make any sense

    I made the move because of Thunderbolt and QuadCore Horsepower, I was fine with graphic cards.

    Now I am wondering if 2010 MBP battery's would fit into a 2011 MBP :

    Just guessing here & it's probably not by much, but wouldn't the quadcore save some batt life compared to the dualcore?

    yes that, while i can't confirm or deny that the battery has a smaller capacity, besides ILVEFRMNYC information, i can also say that downloading gfxcardstatus , and forcing the integrated graphic card while on battery power should help too.
