MBP battery life

[jaxstate]

Can anyone with a Macbook Pro tell me how much battery life they get on a full charge. I only get about 3hours on a full charge. Apple's site says 4.5 hours . Has anyone had 4.5 hours of battery life.

Yes I have calibrated my battery.

Ok, if I cut off bluetooth, dim the display, and let the MBP sit, it jumps up to 4.5 hours.

That's what the battery life is rated at/for. It's the maximum length of time it can operate, and in order to go for so loing it needs to save power, ie Cutting Bluetooth and AirPort, dimming the display heavily, throttling down the processor and making it sleep after 5 seconds of inactivity. With these you can even get around 5 hours. The thing is you just cant run very many or even any at all.
