    Odds are you probably have a lot more than Safari and iTunes open. Is iTunes playing music? Are you watching YouTube videos or something? These can all contribute.

    A big thing is screen brightness. The difference between having your laptop at full brightness and close to dark can make a huge difference. Try keeping the brightness as low as comfortably possible so you can maximize battery life.

    Energy Saver settings, but, Coconut should tell a lot of information.

    Try downloading Coconut battery or battery health monitor. This will provide info on your battery capacity and health

    Thankyou very much for your input:cool:

    Open Activity Monitor, see if anything is using up a lot of CPU in the background.
    Make sure you don't have any login items that are set to hide themselves.
    Try recalibrating your battery.

    Okay. For CPU:

    Safari - No More than 50.0

    Activity Monitor - No More Than 5.0

    Everything else is usually less than 5.0

    I've already re-calibrated my battery.

    If Safari is running Flash apps/video, that's why.

    50% CPU being used is fairly significant in terms of battery life/usage.

    No, that's max. Most of the time it's around 15%.

    Safari, FF, and iTunes are currently idling on my machine right now, taking up a combined 8% of the CPU. You must be doing something within those programs that is sucking battery life.
