I'm sure brightness varies on different phones like all other screen attributes, even on the iPhone X. In my case, while my iPhone 8 has a very nice even, white screen, it is considerably less bright than my iPhone X. Looking at a few models in the Apple store, some iPhone X models were brighter than others even on the same settings. They all displayed different hues and degree of color shifting as well.

It is something to see, I just went to the Apple Store. I put the iPhone x and my iPhone 7+ and the 7+ is way brighter. I checked same apps, same web pages. True tone off. But the notch doesn't bother me, but the screen is definitely less brighter than the +
But you probably didn't turn off Auto Brightness on the X's. With that feature off any X is brighter than all the previous models.
Also, the X has a new hardware feature that dims the screen if the phone is warm. You would need to let cool off first in order to see its real max brightness.

If you go to your general settings then accessibility turn off auto brightness and right underneath there is something called “Reduce White” turn that off as well it made a HUGE difference

I was about to return my phone :-/
 
Sorry for the late reply. We tried updating, restoring, the works, and the results were the same despite the same settings.

You have “reduce white point” on
 
I just got mine today and was immediately disappointed with the brightness (out of the box, it looked abysmal next to my old 6). After playing with the settings that could have anything remotely to do with the brightness/warmth of the display (of which there are many!), I stumbled on the solution: you have to disable the Reduce White Point option under Display Accommodations. Turning off Auto Brightness (under same) and turning off True Tone (under Display & Brightness) helps to boost brightness further still, but Reduce White Point is king!
 
What are u talking about?!?

Reduce Whitepoint is off by default... u would have to have turned it on for u to be able to turn it off...
[doublepost=1511240125][/doublepost]What are YOU talking about? Apparently there is no standard default setting. Some iPhones come with the Reduce Whitepoint setting enabled. I KNOW mine did. See post #78 in this thread (which I did not read until after I posted)

Chill. :-/

Hi everyone! I think I have the solution. It seems as though some iPhone X models came preset with the “reduce white point” function checked.

Settings>General>Accessibility>Display Accommodations>Reduce White Point & Auto Brightness

Turn off both for max brightness.

Also just to share a story/vent, I noticed my X was 50% less bright than my 6 so I did a hard reset and messed with the settings and couldn’t get it to improve.

I went back to the Apple store and talked to an employee who was super dismissive of my concern and assured me that’s how Apple intended the screen to look. I told him that I thought he was wrong and he cut me off and asked if I just wanted to return or exchange it.

Since I had just gone through the entire restore process I did not want to so he replied “well that’s how they made the phone and if you don’t want a new one then I don’t know what do for you.” I asked “Can I please just have a second opinion?” He replied “my opinion is that the screen is working perfect.” I said “I know that’s your opinion, that’s why I would like a different one.”

Finally, after all that hostility () the employee called over a coworker and asked him to give me a second opinion. The guy took out his X and compared the two, looked at my settings and instantly noted something was wrong. It actually took about 3 guys huddled together to get to the issue. Hah!
That didn't happen or was very rare during the early Apple Store years under Ron Johnson (?? forget his name). The Apple Store is like any other store, maybe even worse. I sympathize and empathize with them as the stores are constantly busy with endless customers coming in. Maybe hire more people? But yeah, many workers there are bitter with it's just a job attitude. I remember when they were genuinely friendly. I had the same display brightness question and much better to come here. I shut off Auto Brightness and it's much better! I was prepared to just live with it as I too didn't want to do re-setup again.

I know True Tone is supposed to make the colors look consistent over different lightning conditions. How does it do it? It seems to work by making the display warmer (yellow). Right now, I have True Tone off and it looks like old my 6s+ display and I'm happy. I guess I'd turn True Tone back on if I know it was better, "superior".
 
I looked up this site because I ran into the exact same thing - and had my iphone 7+ right next to the X and had the same issues as the OP no matter what I did with the settings. However, this was while all of my apps were downloading as I did a restore from backup.

So a few hours later after everything had installed and I rebooted the phone - the display now completely blows away the iphone 7+ and all the display settings are live and responsive. Hope this helps

I saw the dim screen (in one those battery drain test videos). The phone was just playing a long youtube video and the phone was stuck with dim screen (and the brightness control has no effect). Maybe the temperature/cpu was too hot. Strange thing is the other iphone X in the test didnt exhibit this behavior. I think Apple needs to fix this. Screen is the most important and it doesnt make sense to give priority to other components over it.
 
I have mine arriving today but went and checked out the X at the Apple Store. I was expecting the OLED screen to pop but it actually looked less "punchy" than my 7 Plus....disappointing for sure...especially when compared to a Note 8.

I checked all the settings and it was set to max brightness. I tried with True Tone on and that did not help either and made it look more yellow. I love True Tone on my iPad but not impressed on the X.

Overall, I was let down by the contrast/brightness for sure.

Go to settings, then display and brightness. Disable True Tone. Then it will be brighter.

It’s been discussed many times before: the X dims the screen when it gets too warm/hot. It’s embedded within the hardware. There is nothing to fix. If Apple didn’t have it implemented, the processor would get way too hot and slow.

you have to turn on reduce white point and slide it to the left all the way to 25% and then turn it off and then turn off auto brightness

Makes total sense.. When all of the apps were downloading and installing the phone was very warm.

Now all that's over it's been running cool as a cucumber..
 
I found that turning off the Zoom setting under accessibility had a significant effect on the max brightness. Don't know how those two are connected but when I switch the zoom setting on my iPhone is very dim even when having the brightness slider all the way up. Some of the other suggestions on here, specifically those about the reduce white setting, really helped as well.

I had the same concern until I did some digging. Make sure auto brightness is turned off - you will see the screen able to be almost too bright. It’s buried a little deep in the menus.

Was disappointing to me. Didn’t feel like it had any punch. iPad Pro lcd seems better except the blacks.
 
Hello, just happened to this also. Brightness is active until bottom halfway, from half to the upper half it remains the same. I was using it under direct sunlight and sensed it was overheating a bit. Thought it was a self protecting feature from overheating and prevented it to increase the brightness to the max setting. how about your experience? did you feel it was getting hot when it happened?

It is back to normal now now that it is colder.

Thanks for the post.

I just got mine today and was staggered how dim it was next to my 6s. However your tip with turning off the zoom setting fixed it - what a difference! Had to turn it down off max to save my eyes. This must be a iOS bug though, there's no reason for the zoom setting to alter the brightness.

There's a low light filter option for zoom. Back when there was a home button, a quick triple click would cause the phone to "zoom" and if you had it set up correctly, it would activate or deactivate a low light filter. Was a very quick way to make it dim in a dark room like a movie theater.
 
I realized out the box the contrast is turned off go into setting accessibility then hit increase contrast you’ll notice a huge difference now the displays looks better then the note 8

This is it, mine just woke up this morning much dimmer and the solution was turning off the Zoom setting as your suggestion. Brightness returned right away, all solved.
This should be passed on, thanks for posting!
 
Brightness was a concern of mine, but mine definitely gets brighter than 7+ And my 7+ screen is solid.

It’s likely panel lottery, and a bad one at that statistically
