Display
The display on the iPhone SE is one of its selling points, but not due to its specs. The iPhone SE takes the place of the iPhone 5s in Apple's iPhone line, and like the 5s it has a 4-inch IPS display with a resolution of 1136x640. While there's no way to confirm whether or not it's the exact same panel, you'll see in a moment that the characteristics are similar enough that it's probably safe to assume that it is. To evaluate the iPhone SE's display I've run it through our standard display test bench that examines peak brightness and black levels, along with the accuracy of greyscale shades and both color saturations and color mixtures.
Apple rates their iPhone displays for a brightness of 500 nits. There's always some degree of variance, but it's always the good sort where you're getting more than you paid for. In our iPhone 5s review we saw that it had a peak brightness of around 500 nits, while the iPhone 5c reached nearly 600. This iPhone SE is similar, with a peak brightness of 598 nits. I wouldn't expect this on every unit, but it's just interesting to note because I've never encountered an iPhone 6 or 6s that was so far above the spec.
The black level on the SE at peak brightness is quite high. Part of this is due to the fact that the screen has a bright backlight, but ultimately even with the high peak brightness the contrast ratio is well behind what you get on other phones, and even compared to our 5s unit it's quite low. It's important to note that Apple only ever rated the 4-inch iPhones at 800:1, but when you put the phone side by side with modern IPS displays on devices like the iPhone 6s, and the LG G4, the black ends up looking more like a dark grey.
The iPhone SE does quite well in our greyscale test. As usual, there is a degree of blue shifting, but it’s not too severe and the CCT average is below 7000. The gamma is quite straight, and in the end there aren’t any shades of grey with a DeltaE greater than three, which is generally the goal. With an average DeltaE of 1.87 there’s really not much more you can ask for.
The iPhone SE renders primary and secondary colors with a high degree of accuracy. The DeltaE for many colors is below one, which means the error cannot be perceived by the eye even with the colors side by side with the true reference color. In the absolute worst case you get saturations with a DeltaE of 2 which is quite impressive. With an average DeltaE of 1.24, there’s really not much that Apple could improve here.
Given that accuracy with color mixtures is just a function of saturation accuracy and greyscale accuracy, it’s not surprising to see the iPhone SE perform well here. There isn’t a single DeltaE error over three, and in general most are between one and two. The overall error is 1.46, and there’s little improvement that Apple could actually make to the accuracy of color mixtures.
Ultimately the iPhone SE ships with a solid IPS display. At 1136x640 it’s definitely not the highest resolution display on the market, but Apple does give you best in class color accuracy, and at 326ppi it’s still high enough resolution to not have really obvious aliasing. Apple was definitely not going to move to 1704x960 on their $400 4-inch smartphone, and a boost in resolution will likely come with whatever Apple’s next 4-inch iPhone is.
Given that Apple is in the process of moving their devices to the wider DCI-P3 color gamut and likely moving the iPhones to a 3x scale resolution, it’ll be interesting to see where the iPhone SE’s display stands relative to the next generation of iPhones. With sharpness and color accuracy being equivalent between the SE and the 6s, the only significant difference in quality right now is the lower contrast ratio on the SE. Apple most likely plans to keep the SE around for two to three years, and so that gap will widen as time goes on.

I bought one. I love the 4" phone.zeeBomb - Monday, May 16, 2016 - link
Dang this review took ages, but nice.Brandon Chester - Monday, May 16, 2016 - link
I have to apologize for the time it took, it's probably two weeks longer than it should have taken. I was in the middle of moving to a new city and also starting a new job during the course of the review which is what caused the delays.zeeBomb - Tuesday, May 17, 2016 - link
Oh! No worries then. When life happens, all you can do is just adapt.Neonomide - Monday, May 16, 2016 - link
Bundling a 10-15W charger with the phone would be stupid, as the battery cycles would suffer. Charging a phone battery too fast takes a toll on battery life in the long run and that's the main reason Apple does not do it.TheinsanegamerN - Monday, May 16, 2016 - link
Doesnt seem to have affected my coworkers iphone 6 at all, despite him using a ipad charger.Apple's charging circuit should only let in as much amperage as the battery can take without suffering damage.

iPhone 6 can take up to 10W I think, not only for charging but also for powering itself. It charges a good few minutes faster than with 5W, the more you load the phone the bigger the difference.Plus iPhones take quite a bit more power for just charging.
What I find interesting that it can use up 5W to charge it's 6,21Wh battery much faster than 5S. That's deffinitelly in part that iPhone devices prior to 6 took some bit less less than 5W to charge, but still the difference is almost faulty looking to me.
Then we got MacBook and iPad Pro charging in 2 hours at 29W, 9,7" iPad Pro supposedly charging super quick (~3 hours) even with it's included (pooor poor 10W) charger, great for a tablet, not ultra quick, but there is Apple smart battery case which can take some super quick charging times when conected to 10/12W iPad adapters.
The question is, what will happen when you connect this phone to a 12W charger ? Can it take more power in like iPhone 6 does ? Does it have that mysterious battery tech like SBC , which gets soaked quickly ?
Not to say Apple wants to unexpectedly come up with fast charging, I think they are going after it for some time, but what does that mean for the next iPhone... Ultra iCharge confirmed ?

I own this phone and two things that drive me nuts are:1: Bluetooth calls sound like crap - this is a known issues and is being fixed in the 9.3.2 beta
2: Cell reception is sub par - I work in a basement office and regularly get disconnected in the middle of a call (I also use a Nexus 5x and never get disconnected). If I turn on Wifi calling it still happens.

I'm very glad to read the details of this comment (mainly re the Bluetooth fix). I own this phone - it replaced a 4S purchased upon release. I was motivated enough by this issue to register with Anandtech in order to comment!The phone in general seems quite good, but the Bluetooth is unusable in my car (a 2012 VW that worked great with my 4S and every other phone) and in the few other cars in which I've tried it. Bluetooth has worked fine with a Mini Jambox. Apple has consistently denied responsibility for this problem to me and (if you believe the internet) many other users, but I've seen online that they have also at times stated that they are aware of the problem and working on a fix. I'm hoping the issue is software and not hardware. If they roll out a fix soon, it's no problem for me as a consumer; if not, the phone is very nearly worthless. I advise anyone buying this to immediately test it with your Bluetooth before giving up your old phone.

Follow up: downloaded the update and have used phone on Bluetooth in my car. Better and good enough to use; still not as good as my old iPhone 4S or many older phones: Overall, happy to have the update. Phone itself has proven very usable. Love the size, and yes, the bezels are too big and outdated; would be great to shrink the bezels for either same overall size and more screen or same screen and smaller overall size. Using what they had, though, is probably too deliciously profitable for Apple and suppliers to pass up.
