Am I only one with this? : Got new macbook, and every time it gets 100% charge immediately after unplugging it, I am checking a lot when it's coming to 99% and trying to make the battery consumption low. When it hits 99% , I tell to myself it's lost, ideal dream is over, let's use it into its full power. And typically adjust brightness, turn on things I was holding on. But it's changing with time :D Sometimes I feel like it's overheating, or too quickly discharging.
