    Why don’t all our phones have e-ink displays? It’s easy on the eyes, it’s more power efficient… what’s the catch? The Kingrow K1 phone with an e-paper display shows us the good and the bad…

    It should be noted that this phone can't be bought anywhere any more, the only ones I could find that one could watch out for (they're not being sold yet) are the Hisense A5 and A6.
    The A5 will allegedly only be 100$, so... damn.

      This actually looks very exciting! It's a shame that I wouldn't be able to play puzzle games or watch youtube videos on it but the improved readability and long standby times would quite possibly be worth it.
      Although I guess I'd then have to use the Android device simulator to use Tinder (if that even works). :P

        Wow. This review did not do the phone justice. This is not the phone for social media addicts. However it’s good for reading and communicating. Btw this phone is not back lit but front lit. Huge difference. It’s beyond me how someone who reviews tech can be oblivious to this.

        Personally I would categorize this phone for people who want get away from social media ie. dummy phone and still have features of smart phone. But your review was not geared towards the people it was intended for.

              I want this, but not for $350

                Hisense a6 is better than this.
                Despite it has two displays - AMOLED and e-ink it costs lower.

                            Nice idea, but too expensive. Aside from Kindle and other e-reader apps, there isn't much point in it going all out on as a smart device. Better to scale back in as many ways as possible.

                                I'd buy a phone like this if they improved the framerate and it had a more decent cost. I'd use a normal phone for picture taking, social media managing, and this phone for messaging, calling, reading... things that I do most of the time anyway.

                                        You know people give apple shit for "gimmicks" and same for google but everything about this phone screams gimmick its useless having an old nokia is more useful then this.

                                              02:37 Let's talk batteries.🔋400 hours of standby time is almost 17 days. 20 hours of talk time is about 5% an hour.

                                              Why is this considered exceptional? Every phone I've owned has 13 to 20 days of standby time. Or more. My tablets go even higher. And I can add a power bank for $20 to double or triple those numbers again. 5-6% an hour for call time is normal.

                                              These aren't theoretical maximums. They're the actual numbers I get when I measure my devices. (0.1-0.3% an hour when idle).

                                              I don't get the point of their claims at all. You can buy a second battery or a power bank to completely negate any issues with running out of juice, and it doesn't cost $350. That's a heck of a lot to pay for an e-ink screen. Heck, some people are saying this would be good for an emergency phone. If you need to conserve battery just turn it off until you use it.

                                              Something doesn't add up here.

                                                I leave my phones amber nightlight on; you don't even notice it after a few minutes. If I turn the nightlight off now, it is so harsh, and I immediately turn it back on. I also keep brightness at 15%. I can see the screen fine unless I'm in direct sunlight.

My phone holds usually more than 2 days. I guess, it's because I'm not so interested in checking it every other second. Not like I have there to check something.

                                                                                Also guys? This isnt competing with cheap smartphones like the redmi. Its competing with the Lightphone and Punkt

I know a lot of scientific equipment manufacturers that could benefit from these screens because they can't match the brightness of a basement dwelling priced smart phone with their current offerings and don't need high refresh rates or color...
