Hey guys i just upgraded to yosemite I have a 2014 2.6GHZ MACBOOK PRO RETINA The computer is barely a month old and has barely anything on it. So I decided to update instead of a clean installation. The thing is after the update my battery life has taken a hit , it shows a battery life of only 6 hours as to before where it would show 9/10 hours. My brightness is minimum and only app running is safari. Secondly my temperature is now around 55*C while before it use to be 45*C Is this normal?
