The battery life is very good. With low screen brightness and keyboard illumination and Wi-Fi, the Zenbook easily lasts 6 hours of intensive continuous use (surfing and coding) or about 4 hours of Full HD video playback with headphones before it screams for the cable.
I use Linux, and according to people I know, the runtime under Windows is even slightly longer (about +1h).
With the WLAN switched off, the battery life increases by another hour.
If anyone else is interested in running this Zenbook under Linux, I can recommend the following link before buying:
