Two weeks ago I took home a new 15" MBP. Other than minor cosmetic style issues the only issue I've had is poor battery life. She's a 15.4", 2.4Ghz, 4GB RAM, 320GB 7200RPM drive. I have bluetooth turned off and just browsing the web I'm getting maybe 3:15 of battery life. I pretty much just have Firefox and Adium up. I also turned tried turning the screen brightness down to 30% or so. My late model white macbook was probably getting a full hour more of unplugged action. I have "Better battery life" set which I believe should turn off the 9600m. I performed the steps in the calibration KB article last night. Coconut battery says my battery capacity is 4764 mAh which is higher than the rated capacity. Is there anything else I can check? I thought people were doing much better than this on average from what I've read!
