I have to work, sleep, eat, even talk to other people etc. There are plenty of opportunities to top off the battery, and you can use fast chargers as well.
If it were a dedicated reading device, no need to play video games etc., you would not need a high performance CPU or other components and could manage wireless energy more aggressively. A 6-inch, say 360 dpi OLED screen would probably still make it cost more than an Oasis but with great color and great contrast...but it won’t happen unless OLED gets dramatically cheaper to manufacture. And probably even I wouldn’t buy one.

Increasing the battery of an ereader to match the battery size of an iPhone XS would also increase the weight of the ereader. As for adding fast charging, wireless charging, etc., these are going to increase the weight and expense past the point where I suspect most users would be happy with it.
I do have to agree that the cost of the OLED display would have to drop very dramatically to make it cost effective. The last time I was looking at a project that used a 6" display, the OLED display option added $280US to the cost with the base LCD/LED backlight screen.
