Hi guys! I tried to do a search on this but couldn't find any satisfying answers. I got my 13" MBA ~8/2011, and my current battery stats are: Age of your Mac: 23 Weeks Loadcycles: 67 Current capacity: 92% Now I'm not complaining about these stats as I know they're normal and fine, but any suggestions in prolonging battery life (as in capacity)? I read the pretty intensive/thorough post from the forums regarding the battery in apple products, but was wondering how you guys are using your MBAs for the most part. I have ~4-6 hours of lecture a day that I use my MBA for, and I used to just use it on battery at school and come home and charge it until the next day. By the time I come home it's at about 10-15% charge depending on how many hours of lecture I had. I recently started using it as my main as well at home (leave it on AC adapter with an external monitor + wireless kb/mouse) since I sold my desktop and am in the process of obtaining a mac mini. Would it be more...efficient(?) (I guess that's a good word) to use it on AC adapter while at school, and maybe allow it to drain to 50-70% (I read 50% in the post on batteries, but I've also read about users doing it to 70%) on battery every 2-3 days as I use it? Or would it be fine to just keep using it on battery at school and charging it at home as I have been? Thanks in advance!
