    My last MBP was a 2009 15 inch with 500gb hard drive, 2.66 C2D, 4gb ram, and gave me 6 to 7 hours of battery life on average. My newer MBP is a 2010 15 inch with the same 500gb hard drive, 2.4 i5, 8gb ram, and gives me 5 to 6 hours of battery life on average. I calibrated the battery properly on the new one and my battery cycle count on the new one is 14. The battery is also listed under the profiler as being normal. I was expecting to get battery life that was longer than the previous gen. Am I missing something here? My usage and brightness settings are the same for both laptops. Also, these readings are when I'm using the integrated graphics and not the discrete.

    How do you normally use your laptop and how many cycles does the battery have? I'm guessing there is some sort of break-in period for the battery. I have been using gfxcardstatus and even though it's always on the intel, I never used the"force" option. I will give that a whirl and see what happens. Thanks!

    Lithium-type batteries don't require a break-in period, just an occassional re-cal.

    Ive never exceeded 6-7 hours. Intel gfx only, with SSD, wifi, med-brightness

    Slightly different comparison: My late 2008 15 MBP never really got more than 3 hours (maybe it did on the first day ...). This is a unit with an easily replaceable battery. My mid 2009 13 MBP gets 8-9 hours easily. I've updated the memory on the latter to 8GB, and it lasts and lasts. That said, if I am running VMware on either system, you can practically see the battery run down before your eyes. About 90 minutes or less on the 15, and 3-4 hours on the 13.

    my 2009 15 gave me about 5.5 hours maybe a bit longer. My 2010 i7 gets 4 if I am lucky.
