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.
Got a tip for us?

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.
