I have bought a MacBook Pro retina display last week and I wanto to know what is the best method to save the battery. I have read that I have to unplugged the MegaSafe until the battery is less than 20/30% after I have to plug the MegaSafe until arrive at 100%. Every month I have read that I have to discharge the battery until 0% and after charge it. Is correct to mantain the battery life?
