    hi all,
    i noticed that the macbook alu battery capacity is about 20% less than macbook air, however, i have got much long battery life with macbook alu. besides, the intel processor for macbook air is designed to consume less power. anybody knows why macbook air is having worse battery life?

    MacBook Alu's battery is bigger to begin with. The MacBook Air might not conusme as much power, but the MacBook Alu's battery is so big compared to that of the MacBook Air's to begin with.

    ya, physically speaking, macbook alu battery is indeed bigger, but from the system profile, macbook says the battery capacity is around 4250 mAh, and macbook air says 4950 mAh

    It's like if my 4 cylinder nissan sentra gets less mileage per gas tank than my buddy who has a big Escalade which sucks that gas like crazy.


    My gas tank is 40 liters (10 gallons) and his tank is 100 liters (26 gallons)

    So naturally he has more 'power' to draw from...

    maybe I didn't understand that example ...
    The MBA has the accu with more capacity and should have components that consume less energy.
