hey guys, i'm running the top spec haswell 15" rmbp, and finding the battery life much lower than advertised. I should note that I previously owned a mid-2012 15" rmbp and had some issues with the battery life that slightly extended over time, but never got more than 4-4.5 hours on a single charge. I've had the laptop for two days now and cycled the battery 3 times, right now it's at 100% and displaying 3hrs 40min remaining. I'm only running safari, display is at 100% brightness, keyboard backlighting is off and graphics switching is on meaning the iris pro is running (not the 750m). Really hope it improves, how are you guys finding yours?
