    I have one also and I'm experiencing bad battery performance issues, I will make a Genius Bar appointment to deal with this, I believe is a defective battery.
    I had calibrated the battery several times without success.
    My battery lasts 2~3hours maximum. It should be for 5 hours?

    I assume :apple: is aware of this and could be the reason why the new ones have the sealed batteries on.

    Anyone else having this battery poor performance issue?:mad:

    here are the instructions for the calibration:

    The "official" numbers are typically quite inflated. Depending on what you're doing, 2-3 hours is reasonable. It also depends on the cycle count of your you let it drain often? If so, the use can/will wear it out eventually.
