On average, I think I am getting around 3 hours of on-screen time. If I am a little more conservative with the things I am doing, I will go over 4 hours. If I keep the brightness lower, I am sure I could go longer... but it has just been so damn sunny lately.
Up to this point, my average day consists of: web browsing, heavy messaging through free messaging apps like kakaotalk and weixin (using gps), flipping back and forth through translation/dictionary apps, a bit of music, and 20-30 minutes of tegra games.
I'm happy with it. It's funny because when the reviews first came out, commenters everywhere were bashing the battery. But here I am today, with 4 hours+ of screen-on time, normal usage, and it was 12 hours til my phone shutoff. Of course I would always appreciate more time if improvements can be made to the tegra 3 drivers, but hey so far so good.
