I realize it's a bigger screen, but they said it was supposed to be higher resolution! It looks terribly grainy compared to my sharp 4S.

Why is the resolution on the 6 worse than on the 4S?
iPhone 4S
960-by-640-pixel resolution at 326 ppi

iPhone 6
1334-by-750-pixel resolution at 326 ppi

iPhone 6S
1920-by-1080-pixel resolution at 401 ppi

The resolution is clearly better so you might want to get your facts straight.

Are you using apps that are not updated for the 6?

My 4 looks worse than my 6.

Maybe it's the bigger text that looks more pixelated?

No I'm talking about this mobile site

I understand what the OP is getting at, though. I also noticed the display on the 6's at the stores looked slightly more grainy than that on my 5s. Very slightly, but it was something I could notice. I don't understand why that would be the case, either. Still, it's a very nice, clear display.

So the increased size makes it worse resolution?
The iphone 6 is higher resolution

iphone 4s 960 x 640 = 614400

vs

iphone 6 1334 x 750 = 1000500


which is the bigger number?



Iphone 6 has a higher resolution then the 4s and the 5s but the same PPI

My 5" nexus 5 has the same resolution as my 80" TV, both are 1080P.

The only reason the iPhone 6 might look worse, is because same apps might not be updated, its all software.

4S is the same pixel density as the 6. The 6 is just bigger and better. 6+ is even bigger and better still. No step backwards has been made

Apps not updated for the new iphone will appear scaled up. That's why you get the impression that the resolution is not as sharp as on the 4S. Give it a bit of time and most apps will get updated with iPhone 6 support.

Including the mobile site for here?

Then something about the bigger size makes the text look more pixelated/grainy.

I've been trying to figure out what in the world you mean, and I think I might have an answer.

My iPhone 5 had a slight issue with the screen where it almost looked like it was interlaced- this is a phenomenon called pixel walk, and it affects certain LCD displays. Needless to say, when my eyes were close to the screen, it was very noticeable.

Maybe this is what you're experiencing? My iPhone 6 does not have this issue, and as a result the screen is FAR better than the one on my 5.

Yup, problem fixed. Thanks.

But everything fit the phone much better zoomed. Shouldn't all of the websites/apps be updated for the zoom?
The zoom is designed to make things easier to see, that's all. It's the regular page scaled up. Maybe eventually they'll improve the resolution for zoomed in view but it may not be a priority.

OP, it's also worth noting that there is a lot more to a display than just resolution. The contrast ratio, sRGB levels, and viewing angles of the 6 blow your 4S out of the water..twice.

Bingo. This is not a HW issue. A big reason apple fought so hard to hold on to the 4/5 width was to make it easy on developers. It's the same reason the iPad mini has the same pixel count as the non mini. Introducing a new resolution without some kind of sophisticated resolution independence means developers have to make new graphics and other resources. And since apple sprung the sizes on everyone, the devs are having to play catch up. The blur you see is a stop gap and should be cleared up for major apps this year and across all apps by the time the 6S comes out.

Btw, the new versions will have to hold the old sizes too, so apps will get larger.

You could try playing with the contrast setting. Mine looks fine! On a bigger screen you need a lot more pixels to make it look sharper.

Zoom mode uses the resolution of the iPhone 5 screen and scales it up to the bigger screen. Standard mode actually uses the full resolution of the new display.

Ok that makes sense. I did notice it went back to the crispness of the 4S/5 when I took it off zoom. Will they ever update it so that zoom looks just as sharp? It's much better and easier to read in zoom I think. Are most people using it in zoom?
