I finally got tired of all the upgrade to Yosemite messages and stupidly upgraded my Macbook Air the other day. The battery life is now ridiculous after having been great for years. I unplugged this morning and it went from 99% to 18% in an hour. I am sure there is information out there on why this is so fucked up, but do you guys know how to turn shit off or change settings so that I can use my laptop as it is intended to be used?
