    Should I take My MBP to the Genius Bar?
    I have previously posted about a battery issue and since followed the instructions for calibrating the battery and still the issue persists. Basically what's happening is even when I calibrate the battery per the instructions on the Apple website about once a month I am never getting more than 2 hours of life from my battery. The machine is less than a year old or I have had it less than a year rather. When I got it I had as much as 6 hours or more on a full charge! Now I get never more than two. My istat widget says Health: 96%
    Cycles: 184 Charge: 83% 1:04 remaining. When I first plugged it in after calibrating it was telling me I had 2 hours of batter time at just 14% charge. How can it be going down now with more charge?

    Should I take it to the Genius Bar? I miss having longer batter life

    It depends on how you're using it. Things that will drastically shorten the amount of time you can go on a single charge include, but are not limited to:

    -listening to music through the speaker(s)
    -anything involving flash
    -burning CDs/DVDs
    -anything CPU intensive (games, movies, rendering, whatever)

    Are you doing any of these things?

    If your battery health is 96%, your battery life should still be very good, so something is draining your power too quickly.

    Launch Activity Monitor and order the processes by %CPU and see what's going on. If less than 15% of your CPU is being used, check spotlight and make sure your HDD is not indexing (this will have the same effect).

    Incidentally, when the mahcine is plugged in, the time displayed is the time remaining until full charge, not the battery life.

    Mostly I am just online surfing. I do not use the speakers constantly nor do I burn cd/dvd very often at all. I rarely do that. I do watch movies occasionally but it seems that regardless of what I'm doing the batter life is pretty much the same. I don't play games or anything. When I first got it I was shocked at how long the battery would last before I had to charge it. Does the amazing battery life only last for a short amount of time before you're down to 2 hours on a full charge after so many cycles? It seems a drastic drop. I haven't change my using habits since I got it.

    I realized that after I posted. Silly, me. I will try the things you suggested. I have actually timed how long the battery lasts to see how much life I would get from my typical use and it's never longer than a couple of hours so I was really going by that. I have been wondering what's up for a few months now.

    OK nothing unusual there.

    Do you know if you're using your 9400m or 9600GT GPU? There is a big battery life difference.

    I'd take it in at this point. Sorry we can't resolve this.
