    Hello,

    I bought a new 15'' macbook pro (the highest stock model they offered) a little under a month ago. Now, I downloaded this system monitoring widget called iStat and it is reporting my battery as:

    Health: 97%
    Cycles: 6

    Why is my health already dropped by 3%? At this rate my battery will be at 0% in 3 years? I dont understand how this works. Also, what are the cycles?

    Thanks

    I was about to make a thread on the same thing. It says my MBP is 2 months old which is weird, because I got it September 18th. It says my battery capacity is:

    95%
    Current: 5231 mAh
    Originial: 5450 mAh
    LoadCycles: 9

    Checked with cocnut battery. Is this considered normal? What is calibrate?

    97%
    Cycles 5

    Got it 6 days ago. I'll recalibrate and give it some time. Also not sure how accurate istat really is.

    Have a blast.

    P.S. I have the same Macbook Pro as you, and ordered it just about the exact same time.
    Current: 6699 mAh
    Original: 6500 mAh

    Just calibrate it.
