Considering that I don't care about taking notes or connecting to stores/apps, I'm asking the experts which of the two would be better for me in terms of battery life?
Thanks everyone.

The Elipsa 2E will win on battery life. The XPPen is an Android device and does not last as long as the Elipsa 2E for reading especially if using colour which must use the backlight.
The Elipsa 2E has an eInk display with a 16 level grey scale 1404x1872 pixel display. The XPPen Magic Note Pad has a NXTPaper display 1200x1920 which is a modified transmissive backlit LCD panel. Either a NXPaper 3.0 or 4.0 display. The front layer is heavily nano-etched (whatever that really means) to give a matte display. There is a weird blue light reduction which, from a couple of articles I saw, shifts the blue backlight from 415-455nm to 457-462.5nm(
*) though TCL's documentation mentions multi-layer filtration. The display can run in a low power mode by turning off the backlight which gives an eInk-like greyscale display useful in bright lighting while enabling the backlight allows colour at the expense of power consumption. The only NXTPaper device I've seen automatically turned on the backlight in dim lighting.
* This struck me as a bit odd since in the numbers I've seen, blue covers 450–485nm while violet is from 380–450. I've attached one of TCL's publications just in case any one wants to read it.
