    my macbook only 1 month old. It is a white macbook, mid 2010 model. Apple says it has 10 hours battery. But my macbook can only work around 4,5 hours. Battery has only 12 cycles,
    normally I do only web browsing and play music. I work with low screen brightness too. Why my macbook can't work 9,10 hours ???
