The health of my battery got really bad in very short time according to coconut battary - on Nov. 18 i had 4936mAh (which was really good). Today it's only 4398mAh, only 95%! If this continues at this rate my battery will be dead in 3 Months! I can't imagine how this could happen - I calibrated 2 days after recieving it, I don't use it on AC Power much, always let the battery die off before charging. I'm pretty pissed - what should I do? Bring it back to Apple - or will they laugh at me for being so sensitive?
