    Will the iphone 7 plus get a 2k screen ? Any rumors on that ?

    Serious question......I know that spec people get very excited with ultra high resolution, and that some manufacturers are feeding that excitement, but did something change where the human eye can now make out anything above 326 ppi?

    More ppi will allow more color differential. You are not going to see more detail, but there will be more depth due to more allowable color differential, and more realistic like photo/video.

    prefer they keep 1080p screen and further increase battery life.

    Even though I get great battery life /w my 6S+, I do agree with the above.

    suuuuure, anything's possible. and then again, maybe not.

    Maybe a native resolution bump to the 1242x2208.

    Thanks for that....seems that if you have normal vision, not perfect vision, and you hold your phone 10.54 to 12 inches away from your face like most adults do, your eyes are not going to see pixels at 326 ppi:

    "It comes down to math…
    20/20 vision is defined as the acuity to discern a detail of 1 arc minute.
    Visual Resolution = (1 / Visual Acuity) * (1 / 60)
    Visual Resolution = (1 / (20 / 20)) * (1 / 60) = 0.0166667 degrees
    Pixel Size = 1 / PPI
    Pixel Size = 1 / 326 = 0.003067″ (iPhone pixel size)
    Distance = Pixel Size / (2 * Tan (Visual Resolution/2))
    Distance = 0.003067 / (2 * Tan (0.0166667/2)) = 10.54″

    Unless you’re able to challenge the definition of 20/20 vision, the iPhone has “Retina” (human 20/20 limits) at a distance of 10.54 inches or greater."

    However, if you hold your phone at 7-8 inches, like most teenagers do, or you have better than 20/20 vision, you could distinguish pixels. The "scientific" studies appeared worthless because they didn't state how close the test subjects were to be able to distinguish between the higher ppi images and the lower ppi images.

    Did I get this right?

    I agree that I'd like better battery life than a better screen.

    So you just ignored the discussed study that reached the following conclusion?

    "Abstract

    There has been a rapid increase in the resolution of small-sized and medium-sized displays. This study determines an upper discernible limit for display resolution. A range of resolutions varying from 254–1016 PPI were evaluated using simulated display by 49 subjects at 300 mm viewing distance. The results of the study conclusively show that users can discriminate between 339 and 508 PPI and in many cases between 508 and 1016 PPI."

    1080P is fine for me. I'll take 1080P Amoled screen over a 2K screen. Anything to make the battery life better...

    Didn't ignore it......the article above didn't mention the 300mm distance used in the study. From the article:

    "Bach set out to test the limits of human vision and the ability to discern differences in extremely high-resolution displays. What he found and published in a scientific journal earlier this year clearly debunks Jobs’ retina display claims. His study had 49 subjects evaluate displays with resolutions between 254 and 1016 pixels per inch. The results of this study proves people can see the difference between a 339 PPI display and a 508 PPI display. More surprisingly, his study also suggests that some people can also discriminate between 508 PPI and 1016 PPI displays."

    You had to clink the link to the actual study abstract to see the 300mm distance, which I did not, so thanks for pointing it out that that study did in fact put the distance at 11-12 inches. But unless you paid to see the entire study, we don't know what size displays the study used. Did they use 4" displays, or 5.7" displays? Remember when Jobs said it was referring to 3.5" displays, right?

    326ppi and 'retina' is a marketing gimmick

    Yep. Just like 3D, VR, and 4K displays on a smartphone. They really reel in the suckers.

    Even though there might be a difference between 1080 and 1440, the fact remains that in both the pixels are absolutely tiny. A change in resolution will make an absolutely minuscule difference in our usage. The whole deal with resolution is blown WAY out of proportion. The displays that we have now are absolutely fine.

    Not if 4K does not improve the look of the screen or uses more power. No reason for it and it would also slow the phone down.

    Brah, don't limit your thinking. 4K all the way man.
