The impact on battery life is marginal. The ZenBook Pro 15 has a 71Wh battery and "up to" nine hours of battery life. An iPhone 8 has a 10.5Wh battery. Real-world power consumption for a good smartphone display is ~500mW. That represents just under 5% of the iPhone 8's battery capacity per hour, but 0.7% of the ZenBook's battery. In the worst-case scenario, the touchpad display will reduce battery life from 9 hours to 8.5 hours. In a more realistic scenario, the power consumption of the touchpad display is a rounding error compared to the consumption of the i9-8950HK processor, the GTX 1050 GPU and the 4K main display. Somehow, people cope with their smartphone being covered in fingerprints.

The article reports several hours battery life difference.

The point is that its on top of the thing it replaced (keyboard). It doesn't matter much if its 10 minutes or 30 minutes, its an unnecessary waste in both situations. > Somehow, people cope with their smartphone being covered in fingerprints. I don't, but if I mostly type and scroll on the bottom, the fingerprints are mostly on the keyboard part. So I tend to read the top and maybe mid of my screen and then scroll further. I actually preferred the time with hardware keyboards for example because screen stayed pristine back then, and phones were much more durable. Alas, those phones are exceptions, and if you also have other special interests such as long-term support, high uptime on one juice load, or the liberty to e.g. run SailfishOS your options quickly diminish. So my smartphone does not have a hardware keyboard, but that does not mean I don't prefer that. Choosing a smartphone is a matter of concessions. Choosing a MBP, idem. Finally, given how often people are replacing their smartphones, I'm not exactly sure if "people cope with their smartphone" in general.
