    I have a 15" MBP from 2011 (latest one) and for the past month or so, battery life has been terrible.

    Here is a screenshot showing that there are hardly any processes and brightness is 50% yet it only shows 3 hours at 92%.

    Any ideas?

    Are you playing Flash video or using the discrete GPU? Try only using Safari with Click2Flash installed and also forcing your integrated GPU to be used via gfxcardstatus.

    Mine's been like that since I got it. It shows I have 3:30 when fully charged. I should probably take it back, again, but I can't be bothered- I've already taken back 2 other MBPs with defective graphics cards.

    There are many factors that contribute to battery life. Read the BATTERY LIFE FROM A CHARGE section of the following link. This should answer most, if not all, of your battery questions:
