As you can see in the graph above, the UL30 mustered "just" 4 hours and 53 minutes before calling it a day. That's exceptional when you consider that display brightness was nearly maxed and Wi-Fi was on, but it's not even close to the 12 hours Asus claims that you'll see. Even if you dimmed the screen as far as you could and disabled Wi-Fi, we can't imagine this machine ever lasting the full 12 hours. Still, 293 minutes of runtime isn't anything to scoff at, as only a few netbooks managed to best that figure.
