I do not know what to do when I play games on my rMBP with my battery. I have read a couple of posts, saying an unclear solution. I want to preserve capacity for 4 1/2 years (When I switch laptops again). I frequently game, so please, can you give me the care I should give to the battery, to leave it plugged in or not, and details, too. Thank you!
