QuoteBacklight consumption should scale with surface area. If a display has 20 % larger diagonal, it has 44 % larger surface area (assuming the same aspect ratio) so you need 44 % more light to achieve the same luminance. 1.56" doesn't tell you anything.
1) 15.6" display have only 11.43% larger diagonal and only 24.16% larger area in comparison to 14".
2) Backlight consumption of modern LEDs is very low.
You can compare idle power consumption of E14(i5) and E15(i7+dGPU): 3.01W vs 3.2W.
0.19W will not reduce battery life from 16h to 9h.

How did an 8% battery life deficit in the most relevant real-use test for a business notebook translate into "10-15%" for the headline, thanks to a 14% deficit in video? :|
