Can calibrating battery reduce capacity?
My Macbook Air is a late 2010 13" model and right now the battery cycle count is 102, condition normal. I usually run the MBA on the battery until it goes down to 70 percent or so then recharge it. Until recently the battery capaciity was 98 percent, sometime 97, but I could not leave well enough alone and decided to recalibrate the battery, about a month ago. Since then the battery capacity has fallen to 94 percent. At the time I did not know that it was not necessary to recalibrate the newer Macbook Airs. I have been hoping the capacity will go back up but no sign of that yet. Right now it is down to 93 percent. Is this normal for a 1-year-old Macbook Air? Should I try recalibrating again or is it likely to make things even worse and to be avoided like the plague?
