My (classic) MacBook Pro (2.6Ghz version, hi-res antiglare + 750GB@7200rpm) finally arrived yesterday and I absolutely love it. My only concern so far is that the battery live seems to be rather on the low end, especially considering what I've heard and read before about MBP battery life. On a full charge he tends to indicate between 4-4.5 hours. That is at about 40% brightness, graphic cards switching enabled and some basic programs opened (mail, skype, chrome with some light browsing, dropbox, google drive and some other small menubar widgets such as little snitch and istat). I haven't accurately measured, but 4 hours seems to be what I get out of it as well (so it's not just messed up time calculations) at (in my eyes) rather light usage. At first I figured it's Mountain Lion, as some people reported low battery live, but I just upgraded to 10.8.1 and the issue still seems to persist (at 80% battery charge I'm getting 3:15 indicated). I also checked activity monitor and none of the applications seems to have an extraordinary drain on the cpu (mail with 3% is currently the highest). Anyone else experiencing similar issues (especially after upgrading to 10.8.1)?
