I bought my MBA about a month ago. i5 256GB. iStat Pro and Coconut show battery health at 98% and now when I charge it, it doesn't go over 96-97% charge even though it says "battery fully charged" and the green LED on the charging cable is on. Is there a way to reset this? I only ever go through full charge cycles (once in a while I'll plug it back in when it's between 40-70% charged. I did the whole calibration from 100-0% when I first bought it. I hardly ever leave it plugged in for long periods of time. Basically once it reaches 100% I unplug although on occasion it does stay plugged in for a few hours. Anyone know why it doesn't show 100% charge or why the battery health has dropped 2% in a month?
