Hi everyone, I got a Macbook Pro 13 inch (my first mac) last november, and Im really happy with it =D. The only problem or concern Ive been having is about the battery. Im really obssesed with my mac being perfect, so Ive read a lot about the calibration, and all that other stuff. But i dont seem to understand what is the correct use of the battery. What I was doing was, as Im in school I take it everyday fully charged and not charge it until I get home, but as I have homework and a lot of stuff to do, I leave it plugged even after it has been completely charged. Am I doing it right? But right now Im on winter break, and I was just using it and charging it, recently I went to the apple store and noticed that a macbook pro like mine just had less than 30 cycles and mine has 38 and I guess the one at the store is a lot older than mine. Why is that? Finally the capacity, acoording to coconut battery, is now on 89% WHYYY??? im really concerned about it. Please help me, what am I supposed to do? Thanks in advance.
