is battery calibration as simple as fully charging and then draining battery ,or is there more steps?
 
ya but do u need to leave it off for 5 hours:confused:

unfortunately yes. when i did mine wednesday night, i just unplugged it at like 6:00, ran it dead at 1:30, left it unplugged til 6:60, plugged it back in until the magsafe light turned green, and bam....more battery life on the estimator. health always says 100% rather then like 99 or 98 now too.
