    So I recently purchased a new macbook pro with these specs.
    2.4GHz Quad-core Intel Core i7
    4GB 1333MHz DDR3 SDRAM - 2x2GB
    750GB Serial ATA Drive @ 5400
    15" HR Glossy WS Display

    I manually installed 8GB of RAM myself, which seems to work fine.
    Even with just basic web browsing etc, I only seem to get around 4 hours of life from it. 2-3 hours watching video. Automated graphics switching is on. I have calibrated the battery, so i'm not sure if this is normal.
    Is it? Thanks.

    Doesn't seem abnormal. Battery life on a charge is based on usage; you don't always get 7 hours.

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details.

    This should answer most, if not all, of your battery questions:
    The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.
