720p video encoding, 1080p video decoding and 1080p via HDMI are considered stunning features?

Heck, Apple's been conservative, and the iPhone 4s has got 1080p video encoding, 1080p video decode and 1080p via HDMI. Androids have had it in 2010-2011 (and were mocking Apple the whole time).

So... the bigger question is - what's the battery life? The performance looks spectacular, but x86 is a notable power hog. And more worringly, I see nothing in the articles about battery life, power consumption, or battery size.
