For casual web browsing, coding, and document preparation, I’m getting just shy of 4 hours on a 6-cell and a little more than 6 hours on a 9-cell. Granted that’s with a quad core mod, IPS display, and full Coreboot, so the typical power consumption with a browser window open might be anywhere from 13 to 16 watts.

How’s your battery life? Any optimizations I might be missing out on?
