    just this last few days, my mac battery has gone from 6+ hours of battery capacity on full charge to now BARELY 2 hours on full charge...

    i have already tried to configure my battery (drain, leave for 5 hours, charge for a full cycle)

    not sure what's going on... anyone encounter this problem...?

    is there anything i can or should i try bringing it back to the apple store...?

    Lets see your battery health print screen then. I cant tell you whats wrong with it unless i know 3 things:

    1) Laptop model and date of purchase

    2) Battery Cycles

    3) Remaining Battery Capacity in mAh.

    Download coconut battery and see if it gives you any clues as to your battery health.

    The link is here:

    If not then take it into the Apple store. You should get a fairly rapid replacement once they've figured out what's happened.

    You can take it to the Genius Bar at the Apple store and they can run a diagnostic in minutes that will determine if it's a defective battery.

    downloaded coconutBattery:

    Current Battery Capacity: 3906 mAh
    Original Battery Capacity: 4100 mAh

    Loadcycles: 74
    Age of Mac: 4 months

    is losing approximately 100 mAh make a difference of 6 hours to 2 hours?

    Ok theres nothing wrong with the battery, its perfectly healthy, it sounds to me like you have another process starting with your Mac OS thats running in the background and drinking all your power, have the battery problems started since you installed some software? Its going to be some pretty hefty software, perhaps some photography import software?

    Let us see a screenshot of your running processes, ordered by CPU intensity. Use Activity Monitor, found in:

    Applications --> Utilities --> Activity Monitor

    Remember to show all processes in Activity Monitor.
