My late 2013 Macbook Pro is 10 months old and whenever I watch a live stream or even a recorded video on twitch, even with 50% or less luminosity my battery die so fast ! I can do 100% battery to 0% between 1h and 1h30. On the other hand, I don't have this problem with youtube... Also, my Mac heats a lot when using twitch... I can feel the heat and the fan starts at full speed sometimes. I'm running Yosemite 10.10.1 Anyone else experiencing this issue?
