I just upgraded to the new OS X El Captain software update a couple days ago. Since then, I've noticed my laptop gets really really hot when it's plugged in and not. I've also discovered that the battery life is less than 1/4 of what it used to be. I used to be able to do a full day in class and have it still be at about 30% by the end of the day. I used it for about half an hour today and it went down to 40%. This was with the monitor at the dimmest lighting possible.
Any advice on what I can do to improve battery life?
