Hi! I recently installed OS X El Cap on my new Macbook Retina Pro 13" and was wondering if anyone else if experiencing terrible battery life. Since, I did not use the computer on Yosemite for more than a day I am wondering if this is a hardware problem or a software beta issue. Also, I have long boot-up times and often takes more then just a click to get my screen going? I am aware this is a beta / pre-release software and battery life can be diminished. Anyone in the same boat?
