Mute point. It’s a common issue on some Apple OLEDs since iPhone X.

Fuel is fuel. It doesn’t matter whether you drive a Mercedes or Toyota, the basic principles of fuel driven cars don’t change. An OLED designed by Apple is just that.
The OLED screen is not designed by Apple.
 
OLED screen brightness can vary from screen to screen. Just like with OLED tv's. One tv may have a peak brightness of 800 nits, and another tv, same model, same size, may only peak out at 725 nits. That's just the way it is with emissive technology.
 
You truly have no idea what you’re talking about. You’re going off track. The OP got my message. He will go to Apple if he is interested in a solution.
 
Hi!

Anyone else experiencing not that impressive screen brightness on the iPhone 12 Pro when set to maximum? I'm coming from an iPhone X and it seems to me the 12 Pro is not that much better in screen brightness.
I noticed that when one switches to Dark Mode, the overall brightness level is reduced when compared to the light mode. I've sent Apple Feedback asking them to not affect the brightness level when using dark mode. I use dark mode all day because I prefer my backgrounds to be dark or black not because I prefer my max brightness to be lower. I noticed that my overall brightness when using the phone on light mode is basically the same as it was on my iPhone 11 Pro Max. Try it out. You might notice this as well and it may be the reason why this is affecting you. To everyone reading this, if you agree with my point then please send Apple Feedback to not allow Dark Mode to affect max brightness level. Maybe they'll "fix" that.
 
I have iphone 11 and 12.

11 has same max. brightness on 100% with autobrightness on or off - in bright enviroment stay on same max. brightness
12 has same brightness like 11 in max brightness when is autobrightness off or if it is on in bright enviroment.
12 has lower brightness on 100% when is in darker room than 11 and autobrightness is on
Max brightness on 12 takes few seconds when is in bright enviroment (or when you set autobrightness off and put slider brightness slider lower and higher). On 11 is instantly on max. level.

If bright enviroment puts my brightness higher than usual I think it's ok. I will not return device with this behaviour.

I also have the iPhone 11 and 12 Pro.
Everything you described here is exactly how my devices work as well. These devices are working as intended.

There is a deliberate difference between how the LCD iPhones(11) and OLED iPhones(12) work in regards to auto brightness.
I'm assuming this design decision is due to the fact that OLED is much more prone to screen burn in at higher brightness levels than LCD.
 
Malnoth : Great. Only difference between 11 and 12 (or LCD and OLED) is that maximum brightness in dark enviroment is lower for 12 (something like 90% of 11 / LCD).
You notice higher brightness for 12 Pro ? (800 nits)

But aakshey in few pages claim that are faulty devices...

With auto brightness turned on, brightness set to max, and in a dark environment, the 12 pro is dimmer than the 11 with identical settings. If I turn auto brightness off on both, the 12 pro becomes much brighter.

aakshey is the only person I have seen who keeps saying these are faulty devices.
I have confirmed with other members of macrumors that this behavior is expected for OLED iPhones, as well as personally tested an iPhone 12 pro, 12 mini, and 12 Pro max. They all function the same way.

He has even confirmed that when brightness is set to max, turning off auto brightness increases the display brightness.
He now claims that it's only when the brightness is less than 100% that it should not get brighter when auto brightness is disabled. I don't believe this to be the case for OLED iPhones. For OLED iPhones it doesn't matter what level your brightness is at when you disable auto brightness, the limited brightness 'range' will adjust to the new full range. It is most noticeable when the brightness is at 100% already, but it still occurs regardless.

The major difference is that the way auto brightness behaves is different for OLED and LCD iPhones.
For LCD iPhones, the maximum brightness is the same whether auto brightness is turned on or off.
Therefore, disabling auto brightness will not increase the brightness.

For OLED iPhones with auto brightness turned on, in dimmer environments the maximum brightness is reduced.
Disabling auto brightness WILL increase the screen brightness.
You will only hit the true maximum display brightness when the ambient light sensor determines you are in such a bright environment that it needs it. For example, outside in direct sunlight.
If you turn off auto brightness, you will be able to hit the maximum display brightness by simply increasing the brightness to 100%.

You‘re doing it wrong. I asked you to test at less than 100% brightness. And I didn’t ask you to compare 2 iPhones. Anyway, best of luck.

Which part am I doing wrong?
Earlier in this thread you immediately told me my 12 pro is defective when I did the test at 100% brightness.
Now you say it's only when it's less that 100% that it's defective. Which is it?

And i didnt ask you to compare. Compare 50% brightness first with AB on with AB off.
 
I always asked you to test at way lower than 100% brightness.
How can you state this with my post above where I literally explained my test is being done at 100% brightness and you immediately stated it's defective.

Please do this test on your 11 Pro and tell me your results...
1. Go into a pitch black room.
2. Turn on AB and set brightness to 90%
3. Open a safari window and go to google.com so you have a nice white background to compare.
4. Turn off AB and immediately switch to safari.
5. Wait 30 seconds.

Your display will get brighter.

I might have missed what you wrote.

My 11 Pro is defective. That’s why I know. I have owned many iPhone X units in the past (all fine except one) and also tested this on many units in store.

So I know.

My Pro is defective so doing your test won’t help you. And I don’t have any other OLED at my place.

I do know healthy Apple OLEDs and LCDs work the same way. From extensive tests that I have done on both.

You’ll need to go to an Apple store to do the above test. It doesn’t necessarily have to be pitch dark. But you shouldn’t be directly under the sunlight either.

Ideally keep brightness around 50%, take or give, but not essential.
 
As long as you’re indoors (even if there is some sunlight, but mostly artificial light or darkness), the test will be credible.
 
As to why I can’t exchange? Because service sucks in India and there are no returns. Unless it fails their diagnostics, 99% they just send it back to you.

In India they don’t try to manually understand problems 99% of the time. It’s just the diagnostics.

Earpiece not working - Buy a new one unless it fails diagnostics.

There are no Apple stores in India. Just Apple authorised service centers which suck.

And in my case the problem isn’t severe. 90% equals to real 75% for me. So not as big a deal. Something I can live with. Nothing I need to fight over.

So we are both in agreement that if you have an OLED iPhone at 100% brightness with AB ON, and then you turn it OFF it gets brighter. Correct?

That's already a difference between OLED and LCD iPhones.
An LCD iPhone in the same scenario does NOT get brighter.

If the max brightness changes for OLED iPhones at 100% brightness when AB is turned OFF, doesn't it make sense that the brightness would increase no matter what percentage the brightness is at? You are simply removing that soft brightness range when you turn off AB.

1. yes

2 yes

3 no, sounds good in theory. But isn’t that way in reality. I have tested it across so many many phones.

Please test it across 5-10 phones, I’m betting the majority won’t show an increase in brightness. But few might. Because the problem is very widespread with Apple’s QC for OLEDs.

Test a big enough sample and I’m guessing the defectives ones might be as few as 5% or as high as 20%. But the vast majority will be defect free.
 
I hope I can help !!!!!
I had an iPhone 11 Pro max with this exactly behavior :
- Screen at 100% AB on and then turn AB off the screen at exactly same 100% is much brighter .
- Screen AB on at 100% in darker room is less brighter than screen 100% AB on in bright room .
IF you test exactly the same way with other values in the screen ( 10%, 20%, 30%, 40%.....) works the same.

Now I bought an iPhone 12 pro max and tested : The results are exactly the same of my 11 pro max.
My old LCD iPhones don't do that only OLEDS.

PEOPLE !!!! This is not an issue is a normal behavior of OLED screens . Apple change the AB behavior of your oleds screens to avoid burning and life span redux.
The AB feature on OLEDS not only moves the slider up and down it analise the environment too and if its too dark the AB will go also limit the maximum brightness capacity because of this if the screen has 100% with AB on in a Bright room it will be much brighter than same 100% AB on in a dark room.

I REPEAT THIS IS NOT A PROBLEM LIKE OTHER SAY THIS IS A FEATURE TO AVOID BURNING AND EXTEND OLED LIFESPAN.
Relax and enjoy your new or old phones ......

They ALL increase in brightness.

This is not a defect, it's functioning as designed. @Gus_BZ is 100% correct.
