    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…

      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.

                                Didn't one phone have a double sided screen? one side was eInk, the other side was a standard LCD screen.

                                    This would be a really great audible/kindle/caller/texter device, but not so much for interactive apps. Would be ideal for people looking to lower-tech their lives or control their media intake... I might have to get one.

                                          Lol. When I bought my first smartphone, I nearly immediately purchased fallout theme app, and colored everything in dull green. 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.

                                              It should have had different color temperatures for the backlight, cool for daytime viewing, and warm for evenings.

                                                As long as e-ink displays are under the monopoly of a single company, they'll never be cheap enough or otherwise viable for phone and tablet use.

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

If it has deezer or spotify l'd consider buying. The latency and so are supposed to be and that is the feature. This was a dumb review. As in he lost the point of the phone.
