Hey all, Before everyone starts jumping to conclusions, I know that Mac's are not ideal gaming computer. I have exactly two games on my 2015 rMBP 13" 1= Star Wars KOTOR 2 and 2= CoD 4. I recently picked up an xbox 360 controller to use during a holiday trip to see the in-laws. I successfully loaded all drivers, and the controller works well for CoD 4. HOWEVER!!!! The battery drain is ridiculous. Is this normal? I'm talking 2.0 to 2.5 hours of battery life on a full charge. When I noticed the quick drain in battery life, I also noticed the fans humming loudly. I typically get 8-10 hours on a single charge with my rMBP. I know gaming takes more resources, but I am shocked at the dramatic difference in battery life. Especially for games downloaded from the Mac App Store.
