I was reading about Apple Portables and Calibrating your computers battery for best performance, and I can not figure out how to calibrate my batter. I currently own a MacBook Pro 13" June 2012 model. I had also noticed that sometimes when I check the battery health it only says Normal, and when I look at iStat Pro it shows 99%, then sometimes it will show 100%. It changes every so often. I only have 27 cycles and always make sure to drain my battery and completly charge it. Please if anyone knows a solution and how to calibrate it would be greatly appreciated.
