I agree that the 70 Wh battery lasting 10 hours implies an average power consumption of 7 W, which is the same as the reported idle power. I'm a bit jealous, because I have an HP 14t-eh, with a similar OLED display with 13500H, and 51 Wh battery, and it only lasts 5 hours under the same test. This means the average power consumption is about 10 W. I'd really be interested to hear what optimizations are being done by Asus to improve the battery life. Two that come to mind are: 1) any special browser addons to make the screen background black while websurfing; this would dramatically reduce the OLED power consumption. And 2) if they limited the clock of the cpu while on battery, such that it can't go into turbo mode. I believe turbo consumes more power per MHz than at lower clocks, and is therefore less efficient.
