Just used my lightmeter on the screen of the iPhone 6 and the iPhone 7, with auto-brightness disabled, brightness set to maximum and measuring on a pure white (rgb: 255,255,255) image I got:

iPhone 6: 740 lux
iPhone 7: 620 lux

That makes the iPhone 7 about 16% less bright than the iPhone 6.
The test should have been done on auto brightness. Everyone is saying the phone does not get to max brightness unless you are on auto brightness.

From left to right, iPhone just for fun, then 5S, then 6, then 7. (Night Shift off on each via turning off the manually enable option.) I see a slight color warmth difference, but no brightness difference. Picture taken by an iPad.

Oh. Just noticed you asked for 50% brightness too. No pic, but that looks the same as well.

So I guess I'll have to re-do this picture at some point, except do it outside in bright daylight with auto brightness enabled. Or somebody else can do it?

Your last comment is simply not true for some. I tested this over the weekend, and my 7 was not brighter then my 6s in very bright sunlight. It was the same brightness or maybe just slightly less bright. You can say all you want about what the experts are saying, what I can see with my own eyes is enough for me. 25% brighter would be very noticeable outside.

Then exchange it or return it. It's that simple. Perhaps you have a defective screen.

This is a joke...this is my understanding now.
The 7 and & Plus *can* be 25% brighter if you choose auto-mode. In certain conditions, in auto-mode, it will go 25% brighter than the 6S.

However, if not in auto-mode, it cannot get as bright as the 6S.

I like mine turned up all the way and never in auto-mode so therefore it will not be as bright....which sucks IMO.

Yeah in very certain situations we can get the screen up to 25% brighter, but real world situations not so much. Come on that is kind of crazy.

I think I read somewhere that there was a feature for the iPhone 7 which would set a limit for the screens brightness indoors (even though it shows as full brightness in settings) but it would automatically know when its outside and get even brighter. Maybe try comparing the iPhone 7 and iPhone 6s outdoors and see if the iPhone 7 is brighter?

I knew I weren't going crazy. For a second I thought maybe I imagined it but turns out I was right ;)

Some people are 25% brighter than others.
I think Apple's fetish to preserve battery is bad.
Look at the underclocked cores of the A10 and consider that background tasks on older devices might consume more energy because the OS will schedule them more frequently.
Why do I claim that? Apple needs to provide the same API functionality even if it has a negative effect on older hardware. This makes you buy the newer model.
The brightness debate is not really that relevant to me, but color temperature and white point is.
Apple did not integrate True Tone with colored backlight LEDs. They did not want to use the light sensor thar measures color temperature and brightness.
Having a wider color gamut but no way to calibrate the backlight?
Apple is fighting for cents and fractions of cents here.
I'm really disappointed.

Read my previous post. I have said many times this won't make me return the phone, it's just kind of frustrating that is only certain situations that it gets that much brighter. It kind of makes me worry about my AW2 that I am getting tomorrow. Will the same be true that only in certain bright sunlight the screen gets super bright. That is kind of ridiculous.

Guess I am a bit confused, you said in the first post it was super dark and turning it up fill it was still dark.

What is the setting you have the brightness on now? I am perplexed as to what changed for it to be much better.

Being in bright ambient light is not a real world situation? I think most people go outside.

Add the interlacing problem on the 7 screens for those who notice it. pixel walk, inversion, screen door effect, whatever you want to call it, it's still present on the 7 screens that I saw. This has been going on since the iphone 5 series.

The screens are all supposed to perform equivalently, but the underlying manufacturers are different. I'm sure which machine processing the way the screens are put together, or the quality of the parts used to power the screen, etc could also affect the quality. So maybe it's not the screen itself but the assembly process being varied in certain plants or assembly lines, who knows.

But it's clear that not all the screens are performing the same, whether or not Apple wants to say they are within their tolerances. What is clear is that the huge premium Apple is charging justifiably allows more "pickiness" from customers and honestly they should be tightening up their manufacturing processes. I'm pretty sure that anyone who cares can see these issues and not dismiss them as random variation.

It may take you 10 phones to get one that you like, but that is what it may take.

Honestly this is the worst, especially if you have good vision this will be VERY apparent to you when the brightness is high. One surefire way to kind of "solve" this, is to go with the plus models. at 401ppi the effect is definitely much less noticeable.

i'm actually surprised people adjust the brightness themselves... it works so well that i never have to touch it.

I own the 6 Plus and like it turned up all the way at all times so most likely will cancel my 7 Plus because of this. Very tricky of Apple. I realize part of the reason is to conserve power since the new home button requires it. I just don't like it...

I'm not trying to be sarcastic here. I adjust the brightness all the effing time.
Auto on or off, it's always wrong for me.

Well I adjusted the brightness myself at first and it really did not get that bright. I then used auto brightness at it did much better. Still indoors I feel like the 6s was a bit better.

Not saying it's not real world. What I am saying is for the phone to achieve its proclaimed brightness increase you have to be outside and it has to be very bright. Does it say that in the Apple marketing material? No it just says 25% brighter. To me that means in all situations it has that potential. That does not seem to be the case.

I have had my 7+ since Friday night. When I first turned on the phone and began setting it up, the display was very dim and I was worried. I've been watching this thread intently since it seemed to be affecting multiple users.

However, either the screen seems to be improving with age or I'm getting used to it. Yesterday I was using the phone in the bright sunshine and literally could not believe how great the display looked. I wonder if the following explanation is plausible: 1) IOS 10 has an auto-dimming feature when the phone is working hard (like restoring, indexing etc.) 2) the wide gamut has a different baseline white point which really throws some people off initially 3) My eyes have now adjusted to the gamut/white point.

That said, I never noticed any yellow cast on my display. It seems pretty close to the white point on my iPad Pro.

Hopefully this will be sorted out soon as more people receive their iphones. In my case, using the phone for a few days seems to have resolved my concerns!
Good luck.

If it's a software issue. It can be corrected. Hopefully Apple will fix it, if indeed an issue.

Is the iPhone 6/6s ever too dark, away from ambient light? I don't think it is. Full brightness on my 6 is blinding indoors.

If it's 25% brighter when it needs to be, that's what matters.

Think about it. If the screen was instead 25% brighter all of the time, all that would be different is that your default brightness would need to be 25% lower all of the time.

Maybe Apple has restricted the brightness increase because of battery life, or to ensure that the backlight does not run down its life excessively. We're not engineers.

Apple designs features like this to be used in the real world. Not for people like us to compare a 7 with a 6s side by side, indoors, and whine, when it's perfectly readable.

There is too much focus on this 25% brighter, the ip7 is not even matching the prior iPhone 6s/Plus display for brightness. 50% brightness on my ip 6s was fine, not hardly for the 7. I have it around 80ish and I can solemnly assure anyone at full brightness without auto brightness that I would not go blind.

Maybe perhaps if my ip 7 wasn't effed up. :)

I figured out the problem with my 7 Plus screen. After comparing to other 7 Plus screen in the store I noticed that Mike was more washed out and darker at the bottom. The Genius Bar has ordered a replacement for me because there were no 7 Plus models available for replacement stock. Hoping for a better screen with the replacement because this one is hurting my eyes.

None of this is borne out in various professional reviews, tests, and opinion.

Either your phone is faulty, which I can't help but doubt, or perhaps there is weight to the suggestion that the iPhone 7 may dim when performing processor intensive tasks when the iPhone is first set up.

All I can tell you is I have been to various BB stores, Apple stores and carrier stores and they all have the yellowish and less brighter displays than the ip 6s and Plus displays. And everyone I showed them to at those places agree.
