Display
As the primary mode of interaction with the phone, the display is one of the most important areas of evaluation. Of course, the methods of evaluation can be hotly debated. There is a great deal of subjectivity in this area in terms of what someone prefers. However, for the sake of color calibration our tests follow world-wide standards instead of personal preference one way or another. This means that we use the sRGB gamut and 2.2 gamma, which most content is adapted to. While AdobeRGB and other gamuts exist, these are for limited use cases and only applicable to operating systems that are aware of multiple gamuts and can dynamically switch between them depending upon the metadata of the content. In order to accurately test for how well a display conforms to these standards, we use SpectraCal’s CalMAN 5 along with a spectrophotometer for accurate color readings.
For those that are unfamiliar with the display of the iPhone 6 and Apple’s key marketing points on this new model, the improvements are mostly centered on higher resolution, contrast, and better viewing angles. In terms of higher resolution the iPhone 6 moves from the 1136x640 pixels of the iPhone 5/5s generation to 1334x750 pixels. However, this doesn’t improve the pixel density, which remains at 326 pixels per inch.
In practice, I definitely continue to notice the difference in resolution when using the iPhone 6 as opposed to the higher pixel density iPhone 6 Plus and the various Android smartphones with 450+ PPI displays. I definitely don’t find the resolution to be a problem though, as these issues only become significant to me below 300 PPI. I do think that around 450 to 500 PPI is the right place to be when balancing pixel density and power, but Apple’s choice should pay off in the form of better power consumption especially because LED backlights rapidly lose efficiency near the highest current region.
The other issue at hand is that of viewing angles. While Apple is one of the first to really talk about dual domain pixels, this technique is rather commonly used to improve viewing angles. The result is that a pair of pixels will appear to be a chevron, and overall the pixels appear to be squiggly in nature. While this doesn’t really change the readability of the display at extreme angles, colors like white no longer have noticeable red/yellow/blue shifts depending upon the angle that the display is shifted at.
This is definitely noticeable in everyday use, as the iPhone 5s could only avoid color shifting at certain angles instead of every angle. As I predicted in the launch article though, the one caveat seems to be that black has a noticeable shift towards purple in certain angles. There's also a noticeable hatching on close examination, but this doesn't affect image quality. This is definitely better than what I see on AMOLED though, as while AMOLED has much better brightness stability the color shifting is far more obvious and significant.
Now that we’ve covered the other two, we can talk about contrast. For this test, we measure brightness of 100% white and black at maximum display brightness, and look at the ratio. While we’re looking into getting patterns that can’t be defeated by dynamic contrast/backlight this should give an idea of best case contrast. In this case, peak brightness is on the high side at 560 nits, with relatively low black brightness at about a third of a nit. The result is one of the best contrast ratios I’ve ever seen. While the HTC One (M7) has a 1743:1 contrast ratio in our tests, some testing I’ve done indicates that the true contrast ratio is realistically around that of the One (M8). I’m not quite sure how this was done, but Apple stated that a new deposition process was used for the liquid crystals. This, along with changes to the liquid crystals themselves, could be responsible for the improved contrast.
The next part to talk about is grayscale, which is an area where Apple seemed to prefer bluer color balances. I don’t really have much to pick at here, because the level of calibration here is incredible. While there is a noticeable trend of overshooting red at the low end and undershooting red at the high end, this is nitpicking at best. At any rate, this is essentially perfect.
Our next test is the saturation sweep, which tests each primary and secondary color for accuracy in hue and luminance. While it’s true that humans can be relatively insensitive to differences in saturation, it is all too common to see OEMs artificially compress saturations to have vivid colors and be able to claim that they have an accurate display because it matches the sRGB gamut. In this test, the iPhone 6 sets a new record. I really don’t have any objections here because a dE2000 value of 1.19 is a deviation that is almost impossible to notice.
The final test is the Gretag MacBeth ColorChecker, which tests various hues and is usually one of the hardest tests to perform well in. In this regard, the iPhone 6 once again sets a new record for accuracy. This display is effectively calibrated to sRGB, and one would be hard pressed to find a significant deviation when compared to a reference monitor.
Overall, it’s hard to find any criticism for this display. I would normally be incredibly suspicious to see these numbers on a smartphone, but the fact that there’s a hot pixel in the center of the display suggests to me that this was not a cherry-picked unit. The fact that I find this level of calibration to be suspicious speaks volumes about how good this display is. While contrast isn't AMOLED levels of black, there are no purple smearing effects, noticeable uneven luminance near black, or any other idiosyncrasies.

A good phone runs its own OS.You and that moron don't understand HD so your obsession is invalid.

He isn't wrong about anything he said, but I just can't imagine getting worked up enough to say it. As a current Apple user/developer, I have every Apple product. I like their stuff, but I can't say I am obsessed about it. I also have a lot of the competing products, so I am constantly toying with all of them. When my current iPhone breaks, I will probably replace it with a Sony Xperia Z3 compact, because it looks like a perfect phone for me. I am not interested in a bigger phone and I would like something that is waterproof, because I run or ride a rain, sleet or shine. I personally think Apple is falling behind in the world of business and multi-use devices. I am seeing a lot of customers whom I developed business apps for iOS coming back and wanting to move to Microsoft or Android platforms because the devices are more powerful and offer more robust features.GerryS - Wednesday, October 1, 2014 - link
I agree. He makes some good points, though most of them are seriously overstated. For most users (yes, nearly everyone in my experience) a "pretty dang good" display is about as good as we can be bothered to look for. I actually like the display on my iPhone 4s. I've never had a complaint, except that it is small, so I got an iPad.See, I don't actually like it that Apple went for big phones. I carry my phone in my pants pocket. The 6 might be about the limit of the size phone I want. If I could get an updated 4s with the processor and other basic features of the 6, that's what I'd buy.
So, for most consumers, we want something that works. I had 4 Android phones before Verizon got the iPhone. I liked them pretty well, but they kept breaking. I went to Apple for dependability, and have not been disappointed. I've only had a couple of problems (even with my jailbreaks), and they've always been easy to fix.
I do like it when Apple leads the way, but it would be silly to expect them to have all of the advances. So many people compare the iPhones to Android phones, listing all of the things that came out first or "better" on Android phones. They seem to forget that there are dozens of companies making Android phones. The best of them have only one or tow innovations at a time - about the same as Apple manages. Apple continues to be one of the leaders, as long as you compare them to one company at a time.
If you want the universe of advances coming from Android manufacturers, then go buy an Android. We really won't hold it against you. For me, I like my iPhone and iPad. My wife has Android (at my recommendation) because we could get some features that were important to her.

Lol, he is wrong about his engine analogy! Seriously, none of that makes any sense. Haha, and what's a "V8 compressor"? My goodness...people shouldn't talk about things they really don't know. Just reading that was cringe worthy.sigmatau - Thursday, October 2, 2014 - link
I'm going to guess you are not so dense as to be picking at the spelling but instead don't know what is a v8 Kompressor. Not only one of the best engines that Mercedes made, but also award winning by 3rd parties.techconc - Thursday, October 2, 2014 - link
Actually, he is either wrong or extremely misguided in almost everything he's said. Feel free to pick your argument of choice. He starts off by saying how the iPhone 6 launch was disastrous. As compared to what? What other vendor will sell 10 million devices on a launch weekend? Even for Apple, it broke their own previous records. I'm genuinely grateful for people that prove they're an idiot right up front. It lets me know I can either skip the rest of the post or read on for purely amusement purposes.That's just the conceptual part of the post. His technical observations were equally misguided. Especially with regard to screen quality, etc. Clearly he didn't bother reading the Anandtech review he's commenting on.

@techconc: Sure, what other products you know starts to bend, or totally crap out after the first buggy update, or even have features withdrawn due to more bugs all within the first week of release?akdj - Friday, October 3, 2014 - link
Really? You're still convinced the iPhone (6 OR 6+) actually and easily 'bends' in the first week? Buggy update? The one available for about two hours that few downloaded and within ten hours of pulling it a fixed update was released? Features withdrawn? I'm intrigued ..as an owner and realist like techconc, the person you responded to... I've GOT to know!I'm patiently awaiting my pair of 6+s for my wife and I. We just returned from the mall and the Apple Store specifically playing for almost two hours with them. I built a two minute movie and. Rendered in 1080p in about 35/40 seconds, air dropped to myself. Un. Believable phone. It's. Amazing
We ordered launch day through our business representative. Lol. Silly me. Ship date estimate is pretty specific, actually a bit ambiguous with the latest update. 11/2-11/28/14:-)
Oh well. Plenty of time to allow developers to continue updating their apps.
Between my Air, rMBP 15" and the iPhone 5s /6+, my business of 27 years has been revolutionized. Literally, over the past half decade, as a pilot and sound/video producer...weight savings alone are enough to double our profits. And ½ our setup snd break down times. Even my 'flight bag' of nearly fifty pounds isn't necessary. With three retina minis in the cockpit for redundancy, the 'paper' is still there, but unnecessary any more for updates to plates and Jep charts, winds aloft and weather/traffic ...even diversion airports, filing my flight plan and telling me how thirsty she is! Fuel calculated, with a GPS dongle a tenth the price and 100 fold quicker to lock n track than avionics just a half decade ago provide incredible accuracy. ADSB and TCAS (3D terrain, weather and other traffic/with their specific info; altitude, speed, heading, and Xspnder --- TCAS, a warning system that 'tells you what to do' in conjunction with other planes fitted with the system including all commercial traffic and many GA pilots with ILS certifications ...Alaska can get nasty quick and having to 'duck down' these two systems alone are incredible and 'reasonably priced' advancements!).
I'm not sure there's a place in my life iOS has t changed. As a father, business owner and operator, little league and wrestling coach, and pilot...each iteration has improved signficantly enough in 'most situations' to justify yearly updates for me. iPhones hold their value. Until the 4s, AT&T was generous and 'allowed' a 12 month subsidized update. With the business I also provide 17 full time employee iPhones so we've been lucky enough to 'recoup' some of the money spent each update
I just sold an employee's iPhone 5, 32GB AT&T with a cracked screen, scratched to hell and working perfectly. With excellent battery health and perfect camera lens (only scratch-less area of the phone!) for $235 to a local repair guy. He saw me in the mall with the Gazelle box (more than a hundred bucks less) on my way to the USPS. Asked what I was sending. Told him. Showed him a 'picture' or seven before I unboxed it, but he was adamant ...he was able to shine it up with his pieces n parts for $45 or less! Told me it would cost a customer about $210 to do the work but parts were 20% the cost ...labor and time is the price. From there he was confident he could sell it for $325-350 at his kiosk within 24 hours.
My son has had his fifth generation iPod touch for two years. He's nine. No scratches. No scuffs. Clean a booger or twelve off once a week but other than that, it's completely 'perfect'. These iPhones are built damn near the same. Sleek, thin and well balanced ...no bugs, incredibly quick and unless you're a dumbass and put your $800 pocket computer in your rear pocket of your jeans and SIT on it, you're an idiot ...and you've got to be SIGNIFICANTLY overweight AND hit the precise angle in order to 'mash' 100 pounds of pressure to a 'single point'/torque.
Can you bend em? Yep. It's been proven and EVERY piece of proof we've seen visually demonstrates the incredible amount of force necessary and in such a way not indicative of daily use or situations a consumer would find themselves in 99.9% of the time.
Don't. Be. Silly. I respond not only to you but to all those talking like you. Until you've used one. Felt one. Actually spent time with it, it's difficult to understand.
These are absolute and unequivably the BEST two phones on the maket at this time. With the best and most abundant apps/software optimized to its specs. Support to back it up. And resale value when Ya get bored and ready for a new one. You'll recover your 'down payment' plus fifty percent in many cases ...if you take care of it. Seemingly, they're even more valuable than a same year flagship Samsung Note 2, as I wasn't able to get more than $125 for that joke. Note 3 got it right. But it took twice the cores, clocked at twice the speed with three times the memory ( ⅔ to ¾ of which is in use even without an app running! I've got one though and don't take me wrong, I love it) to get 'close' to the GUI fluency of the iPhone & iOS
That's. SAD. That's. Buggy. I'd much rather have a phone that bends with a hundred pounds of torque in a certain and specific area than I would gambling I'll get an update, deal with carriers and OEM bloat and shitty aesthetics and design. Lack of support or resale, lack of apps and software ...& the apps and software in parity are incredibly more enjoyable and stable on iOS. I like my Note for browsing and the SPen. I think an active digitizer would put the six plus over the top but as it is, it's perfect.
Indeed, I'll continue using (& owning) my N3. But I'm not the least bit compelled with the '4' and its 2540 display. While I'm sure there's noticeable and 'obvious' benefits to having 550/600+ PPI ...I'll warn ya when you're 38-42, speaking from experience...you'll need 'cheaters';) ...like our ears, our eyes deteriorate as well ...the elasticity of our lens and ability to change and 'maintain' up close focus just ...goes away! Hence the incredible benefits I've found witg the HiDPI display technology. 3D? Good riddance! It was a joy to see 4k/Ultra HD and even examples of 5/6 & 8K motion display AND capture gear instead of dumbass glasses and crappy off center viewing with limited content.
Apple lead the way and destroyed multi billion dollar monsters in the industry with the iPhone. They then changed consumer display technology's availability. HiDPI and increased resolution is awesome. But to a certain point. Your 1080p 65" LED LCD IPS or AMOLED TV in the living room at 10-12 feet or typical viewing distances is around 100ppi. Quadrupling the resolution (4k) while not exactly linear, will amount to approximately an increase of 100%. To 200ppi. Not four foukd as you may think.
The 'new' ipad(3)/4 -- iPhone 4 -- the rMBPs --- ALL Game Changing home runs. Putting a certain 'joy' back into 'work' again. With SUCH an accurate palate and the ability of OS X'es scaling of the UI (& third party apps the same ...utilizing pixel for pixel when necessary or quadrupling for the GUI simultaneously and without 'glitches' or latency is a marvel in engineering. Coupled with the IrisPro 5200/750m and PCIe SSD at a TB with read and write speeds exceeding a Gb/s, Thunderbolt 2 and its 'one' cable capabilities and abilities to run multiple 4K displays ...shoot man. Seems like yesterday I was hunting the wax pencils and cutting my fingers slicing tape ...now it's immediate and fast as hell in a four pound package at a dozen times the resolution.
Times are good if you're an Apple user. And thats JUST the hardware!
OS X and iOS's march to marriage is incredible. Continuity and Handoff. Air drop between iOS and OS X, as well ...the aggregation and integration between the devices you're using is revolutionary. Period. Only Windows has the power and support vertically and horizontally to compete with what Apple's doing. Vertical & Horizontal backbones.
No one that needs to 'work' is buying a Chromebook

This must've been the longest and weirdest Iphone ad I've ever read. ;-)techconc - Monday, October 6, 2014 - link
@shm224 - I now know several people with iPhone 6 and 6+ devices that keep them in their pockets. They all seem to agree that there is no merit to this "bend gate" nonsense. While nobody doubts that these phones can bend under a certain amount of pressure (90 lbs. according to Consumer Reports), from a practical matter, it's a non-issue. Further, I find it rather interesting that phones such as the HTC One which bend under significantly less pressure (70 lbs.) don't receive the same sort of media attention.As for the 8.0.1 update, yup, Apple screwed that up. Fortunately, for Apple, the update was pulled after about an hour. It's also fortunate that in only affected some phones and only for the over the air update as opposed to the iTunes update. To your point, no, this typically isn't an issue for other phones... then again, neither are regular updates.
