Mine is from the much lower-spec (and appropriately cheaper) ZenBook DUO range. The battery life is pretty darn good until I plug in the external screen, and still better than many laptops even then. It isn't often I'm away from a power socket for and needing to work, but when I am, it can be for a fair few hours. Gaming isn't something I find time for these days, so this model is much better value for this use pattern.

Yes, your model makes sense if you dont require gaming. Asus really makes the best devices. I have been theirs's and HTC fan for years. Had Lamborghini laptop from Asus and HTC diamond phone circa 2008-9.
