Hi guys, I just bought the new 13" MacBook pro, and coming from a cheap old dell of laptop, it is amazing. My only concern is that I'm planning on using it for another 3 years, so I want to take care of the battery well. I've read the apple support page, but it's still confusing to me. I mainly use it at home, so I can plug it in all the time. When it's plug in, does the MacBook use the battery at all?. Also, should I charge it to 100% and completely drain it every time, or should I always plug it in, and only run on battery once or twice per week?
