I'm not really mad since I never use the battery anyway but I've had the battery for a week and I have yet to have it last more than 5.5 hours doing normal stuff. The first couple of days I got anywhere from 3.5-5.5 hours on a full charge and this week I fully calibrated the battery again and I only got 5.2 hours out of a full charge. I've attached my dock to show what's typically open, apps like photoshop are just open for quick access but they are not in use most of the day. I program all day so I have CentOS in Fusion running all day so maybe that's what drains the battery but other than that it's email and the web. My screen brightness is two from the highest and keyboard back-lighting is off.
