Hi there, I've been recently been concerned with the battery life of my 13" MBA and wondered if this is normal. I have been using Coconut Battery to log the batteries capacity over the course of a week and this is what its shows As you can see, its lost almost 100mha already and I've only owned it for a week. Can anyone else share their capacities and length of ownership? Also, can someone recommend tips on how to maintain good battery health. I've heard its best to not keep it plugged in and charging all the time cause charging diminishes the battery. So lately I've been charging it and running off the batter as much as possible but still feel it would be better just to keep it plugged in all the time. What do you guys think?
