Reply to comment by CraziestPenguin in Hisense Hi Reader Pro is an Android smartphone with a 6.1 inch E Ink display (pre-order 250$) by giuliomagnifico

7 hours… I mean yeah you can say it’s impressive but look a few years back and we had nokias and blackberries running for 24+ hrs without needing to charge. I would actually consider shifting to something like this for my daily driver as it’s not for media consumption and all, just a tool for communication. Calls? Yes. Texts? Yes. And even other social media like whatsapp, hell even reddit would work for me as text-only mode. I mean, depends on your personal choice and use case, I know I would dig it.

Those old Nokias and blackberries had CPU’s that are, in all honesty, more comparable to graphing calculator CPU’s than what’s in our current smartphones. They also didn’t generally need to maintain a connection to multiple different types of cellular networks like modern phones do.

Thats true, and thats one of the reasons we have less and less battery life, hence, if an E-ink display can give me days of battery life I would absolutely take that, even if it gives me less “features “.

There was actually a phone that came out a long time ago (I think it was called the yotophone) that had a normal screen on the front, and en e-ink screen on the back. It was pretty neat and allowed you to customize the look of the back of your phone.

Yes I did see that a couple years ago, you could even set designs on the back with the E-ink because it never used power when idle so made a cool way of using and demonstrating the tech

You weren’t getting 24 hours of active use. This is just revisionist history

You absolutely were. The 3310 had 22hrs of calltime and about a month on standby

So as an example you give me a phone that had…. Less than 24 hours of active use time…

Active Use Time != Call Time.

The number of hours you could send SMS and play Snake was virtually limitless.

Bro, if you just want a cell phone, you know they still make flip phones, right?

Lol I know, and I have a couple myself, flip and feature phones. Hence my reasoning.

doesn't use e-ink technology which last far in battery perfomance.

Imagine a mobile phone that:

has the power draw of today's chips, but using the old speed (I dunno, 32 mhz?) - same performance, lower power draw, smaller size

has the same battery size as today's phones (more effective battery than the old ones)

has an e-ink display (much better battery life; pretty sure even the passive matrix displays or whatever they were called were less efficient than today's e-ink)

uses only what is needed for calls in terms of radio (no drain from connecting to gps, wifi, 5g, etc. Just regular gsm)

Screen size still tiny (unless there's barely any power draw difference between a 1 inch screen and 4 inch screen on an e-ink)

I dunno if digitizers take a lot of energy, but physical keyboard would be awesome

Anyway, point is, I'd imagine this would be like crazy effective. Even throwing a contemporary battery into an old Nokia would probably make it last like, I dunno, 5x longer. And that's just one change.
