Is anyone else noticing increased battery drain while the computer is asleep? After I did the big November update and the November firmware update, I've noticed that the battery drains very quickly even while in sleep mode. I'm talking from 100% to less than 50% battery life overnight. This is with wi-fi connection off while in sleep mode. As far as I can tell, I have no significant background apps running. Certainly nothing new compared to before the update. Prior to the update, battery drain was still a bit high but certainly nothing like what I have now (before, overnight it would drain to perhaps 85% as long as I have wi-fi connectivity off).
