I just upgraded to the latest core i5 MBP from my previous C2D with the 8hr battery (the previous model). I have noticed that my battery doesnt seem to last as long. On my last one, just reading PDFs in preview I could get 8+ hours with wifi on and half brightness. Now its more like 6 hours under the same conditions, and that's when doing absolutely nothing else. Coconutbattery reports 7000mAh capacity, and I've tried rebooting, resetting pram, checking activity monitor, etc. I even installed gfxcardstatus and forced it to use intel graphics only. It's not generating an abnormal amount of heat or anything. It is possible that my laptop is in some way draining more power even doing normal tasks? Does the flick scrolling feature perhaps use more power? I'm sure if I take the laptop to apple, they will say the battery is ok and hand it right back to me.
