Earlier today I noticed that iStatPro was saying that I only had 98% of my battery left after it finished charging. Now, this is to be expected. It’s hard to believe, but my MacBook is already 6 months old. I wanted to make sure that this was correct so I went looking for an application and found coconutBattery. CoconutBattery also said that I had 98% of my overall battery life remaining and that the battery was fully charged. When I was just looking at iStat i noticed that it said that the battery was at 100% health again, so I loaded up coconutBattery and not only was the battery back to full capacity, but it was higher than it started at, as you can see in this screenshot.
