    I've got a 4 month old Macbook Aluminum 2.4 ghz. I was getting great battery life for the first couple of months. But I'm now getting 3:10 with screen half light, and wifi on, bt off, doing a bit of downloading, etc. I've recalibrated the battery a number of times. According to activity monitor my cpu is hovering under 10% when I'm doing my battery test. This is at least 2 hours less than I was originally getting. Coconut Battery tells me that the original capacity was 4100, but its currently at 4052. Battery load-cycles are at 97 and it says the Mac is 5 months old. Should I take it in to the Apple store under AppleCare?

    It doesn't look too much out of the ordinary.
    For a while, try changing your charging habits. Try keeping you MB plugged in most of the time, and use it on battery only when you HAVE to. But if you have a plug around, plug it in!
    in most cases, this will help your battery get back in shape. It worked for a friend of mine last week, in just a matter of days he was able to see an improvement.

    This is how i've treated mine since day one, and I have 100% health, with 70 cycles, after 6 months.
