Hi All I've got a mid 2010 mbp 15" with the following config owc 40gb ssd seagate 500gb 7200rpm hdd with bt on for the magic mouse and wifi on. brightness set to 1 and no k/b back light. I'm probably getting around 6 hours. Just interesting in what everyone else is getting. I've had it for a month and calibrated the battery twice. I'm using gfxcardstatus to force it to use only the intel.
