It's one of those "it depends" answers, but mine lasts around 4-5 hours when: - cranked the screen to 80% brightness - have two browsers open with multiple tabs (plus YouTube playing in the background) - doing development I'd say it's about average. If you play games the graphics card is going to soak up energy within a couple hours, but for heavy gameplay you'd want to plug it in anyway. I always want more battery life, but it does well enough and has such good specs otherwise that I can't complain.
