    Apple's page about laptop batteries is very helpful:

    Overview: Keep the unit plugged into a power source when possible, unless you're going to keep it stationary for a long period of time. Batteries like to have their electrons moving, so try to let it run off battery power once in a while. Also, when you're running mobile, disable the Wifi and the Bluetooth if you aren't using them, and keep the brightness as low as you can handle to maximize efficiency.

    Edit: Don't stress over battery life. My MacBook's battery is over 100 charge cycles, and there's no noticeable deterioration of battery life.

    Hi, I only get 3hrs max out of my MacBook (It is the new SR specification and I got it end of December), that Is when I use only Safari. I have tried Calibrating it but the life is still the same, It loses nearly 1% of charge every 1/1.5 minute, It also only starts up with about 97% charge after a full night of charging!!!!

    Depending on what I'm doing I can usually pull about 4 1/2 hours with my MacBook Pro 15" 2.2 GHz notebook, with Bluetooth turned off, Airport turned on, listening to streaming radio in iTunes and browsing the internet in Safari.

    Remember to close any unused applications when you are running off battery, because they use up RAM and can be swapped to disk which can cause a little bit of battery drain.
