    Lately my battery has been draining much faster. Is there a program to check which programs are using the most battery?

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
    If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of battery health and cycles and computer uptime, among many other things. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with Mountain Lion. You can download it here.

    Look at the batteries health first, I think you can do this in System Profiler, see how many cycles it has and how many % left from new.

    Open Activity Monitor and look if there are any runaway programs/processes, be sure to select all processes in the top, so that you see your user name and the root.

    Everything seems normal in Activity Monitor. :confused:

    Most usage is Safari with silverlight at 30% CPU usage while I'm watching Netflix. Spotify is 2.8%, everything else 0-1%.

    Hmmm, than there must be something wrong with the battery.

    Edit: I would recommend resetting SMC.

    I blame netflix. It absolutely kills my Macbook Pro mid 2010.
    Rockets my CPU temp to 80C+.

    Running at 30-50% CPU will certainly run the battery flat very quickly.

    Follow the instructions in the 3rd bullet point in the BATTERY LIFE FROM A CHARGE section of the Battery FAQ, then take a screen shot and post it.
