    I just got my MBP two days ago. I decided to download the "Istat pro" widget. The first day my battery health was 100%, now its 99% already. Does anybody knows what this exactly means and if i could improve the health of my battery?

    Calibrate your battery. Read the Apple article here.
    Istat seems to jump around alot in regurad to my battery health. It was 100% when I fist got my MBP, 89% a few days later, then back to 99%. After calibration, its staying at a steady 100% Hope this helps!

    the battery health seems to run down when your battery level goes down.. i.e. battery health at 100% charge may be 99%, but battery health at 30% charge may only be 90%... it will go back up once charged again.

    normally.... (unless you have access to powerpoints all the time) once your battery goes below about 70% battery health then maybe its time to grab a new battery, although people with a battery health of 30% still use theirs.. just dont get much time
