I was looking for the battery life to.

after a bit of digging through their page - 8000mAh battery giving "days" of charge.

So a long way from eink insanity, but a usable device in return. Im sure it will do well.

These types of displays use power to change the pixels, but almost nothing to retain the existing image, so battery life will be wildly variable depending on how you're using it. Browsing the web with nonstop animations versus reading a book will probably show massive swings in battery life.

This isn’t e-ink, it’s a transflective LCD so that’s not true here

It's not e-ink, but it appears to be the same as Sharps "memory" display, which means it continues to show an image even after power is removed. They have extremely low power draw when displaying static pixels

They said it’s not bistable which I think means it doesn’t do that
