don't you need to charge them eventually? so you end up taking them down a lot. they should think about wireless charging pads that can be installed into the wall for these sorts of things.

Sounds like a good idea. Just anecdotally I found it pretty fascinating that I bought a new Kindle some three months ago and it still hasn't run out of batteries (came with 76% and now at 16%). Admittedly I haven't been using it a lot though.

  My experience with Kindles is that the battery drain is all about wifi - if you keep it in 'airplane mode' most of the time (except to send new content to it / return library books early etc.) it can last for months on a charge.

I wonder if trickle charging with a few calculator-type solar cells on each edge of the frame (not the face of the frame) would be feasible as well to prolong battery life.

But that requires a wire that goes from the outlet all the way to the charge pad though, right? I think the main goal is to have no visible wire when it's on the wall. On the other hand 7k image changes before going out of battery seems quite a lot. Just not sure if that's a representative number.

E-ink screens only consume power when refreshing so if you don't change the image a lot you won't need to charge it often

  True, if the processor powers down too.

    Many have deep sleep features where they sip energy.

If that's the case wouldn't it be easier to just have a power cord?

These only need to be charged a few times a year

Even if you completely run out of power, the screen should stay on the last image it was showing. You might just see the same picture for days/weeks/several heat deaths until you decide to charge it again.
