I have a battery issue: starting from about two months ago, my battery has had its capacity decrease by 1% per cycle. I have no idea what it is doing this, as there has not been a change in my treatment of the battery. I go through at least once cycle per week. I have also tried "calibrating" as per the apple article. I have also reset the SMC. Nothing appears to change. What could be the issue? A summary of battery info is here. Note the right column.
