    So I calibrated my battery like it said to do on the Mac website and now, after a full charge, it is saying I only have 5-6 hours.

    What's happening?

    I'm not doing anything intense - just email, MSN, music, internet :(

    Look at Activity Monitor (select SHOW ALL PROCESSES) and sort by CPU usage to see how much CPU each process uses.

    What is your display brightness setting?

    What specific MBP model do you have?

    What is your battery capacity (System Profiler > Power)?

    Have you also taken a look at ay of the dozen thousand other threads about battery life via MRoogle?

    How do I get to the Activity Monitor?

    I have the 2010 13" Macbook Pro - just bought it a few days ago.

    Brightness is about half-way..

    How do I get to Systems Profiler?

    What size MBP do you own? If it's a 15'' - 17'' that's the normal battery time, but if it's a 13'' it may be a sign of a malfunctioning battery.

    RedJeans, have you completely drained the battery, like the guide says?

    Yes, last night - and then didn't use it for 5 hours + (was about 9 hrs) and then plugged it in - just like it says in the guide.

    So how much CPU is used then?

    And have you recognized any jumping around in the remaining time that is given by the battery indicator?

    About 5% user, 7% system

    And it has been jumping a bit - between 4.5 - 6.5 hrs
