I didn't. I tested them at 30%, 50%, 90% and 100% brightness.
They increased in brightness at every level...
That is more like it.

What were the ambient light conditions? How much was the increase? Subtle or night and day?

But, yes, you've done the test correctly if you've tried 30% and 50%.
 
You miss the point. When brightness increases, the level on the slider increases to be in sync. At the same level on the slider, brightness is always constant. Exception - 100%.
 
stay happy with a defective phone or go to a store and test yourself across 10+ iphones. Take it or leave it.
There is different behaviour in store because of brighter enviroment. 100% brightness is same with AB on or off !

Actually, Aakshay is right. I had this issue on my iPhone X. The brightness would increase after 10-15 seconds even when auto brightness was turned off. No idea why. The slider would stay the same but the brightness would increase.

And Nisaja doesn't have this issue with his 11 Pro, 12, and 12 Pro. 3 other OLED iPhones he has done the same test on.

Can you please confirm here @Nisaja ?

Yeah I just checked my 11 Pro. No change in brightness. I checked the 12s last month. No change. My X had that issue.

Exactly. It is a very common issue. Neither your 11 Pro, 12 nor 12 Pro had the issue. But the X did. Because although a defect it is very very common and will happen to 10-30%+ iPhones for every 100 or so you test.

Confirmed, no change in brightness when AB is on/off. Brightness set to around 30%.
Sorry, was a little bit busy. I just ran a quick test and you're right, the brightness seems to be the same regardless AB is on off.

I have a Pro Max, but I need to wait until tonight so I have second Pro Max to compare the brightness to be sure. I'll run another test tonight.
In my experience, anything below 100 stays the same indoor or outdoor. When you push it to 100, it goes super bright whether indoor or outdoor. So if you like it really bright all the time, this is the way to go.
yes I confirm. It increase but just if I put the level to to highest possible
Yes, when setting my brightness to MAX and then turning off auto-brightness. My screen does get brighter. However, this only happens when the brightness slider is at MAX. If its in any other position and I turn off auto-brightness, nothing changes.
My first one was like this. The device failed the diagnostics. I got a replacement from Apple.

My second one looks the same with or without auto brightness.
Hey, so I just tried this with my 11 Pro Max and there is no difference, except for max brightness. My screen has never appeared dull. With auto brightness disabled the screen gets insanely bright at max, compared to auto brightness enabled.

Hey.I have also tried turning autobrightness on/off around 50% on 11 Pro and there was no change in brightness, this was at night and home.And i tested it way back and even tried it today.Got the same result tbh.Akshay you are correct as per me
 
I don't know you guys.. The behavior on the 12Max seems to be different than it was on my 11Max. There seems to be an increase in brightness (level stays the same) with Auto-Brightness OFF. Here are my steps:

1. Open Accessibility and turn ON auto-brightness (wait 5 seconds)
2. Leave the brightness unchanged, and turn auto-brightness OFF
3. 5 seconds later, the screen gets visibly brighter and less hazy but the brightness LEVEL hasn't changed.

I've tried it multiple times and the same result. Doesn't seem to be happening on the 12mini, just on the 12 Max.

🤯

So it didn't happen on the 12 Mini or 11 PM but does on the 12 PM.

Exactly my point. The defect is widespread. Just replace it once or twice if needed, I am sure you will get a good piece. But sometimes might need to be replaced more than once if you're unlucky, that's how widespread this is.

I have owned 5 iPhone X units. Didn't happen on any except one after an iOS update. And then Apple replaced it because it was super super dull and dim.

Thank You for chiming in @VSMacOne :)

I'm not really sure I want to play the display lottery, especially with the current . With the AB turned off, it's a decent display. Much better than some others I've seen out there.

Ya. But how often do you use it with AB off? :)
 
More proof from an 11 PM owner.

I'm still confused aakshey

Do you agree with all my points ? If no - which one ?

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.

That is what I am trying to explain Sir.

My test isn't about comparing one phone to another phone (let alone another model). And it is essential that no iPhone be at 100% brightness for the test to have any validity at all.

My test is simple:

If turning off AutoBrightness increases your brightness/vibrancy (of any OLED iphone) (at any brightness level other than 100%), your OLED iPhone is defective. If the brightness level doesn't change, the OLED iPhone is fine with respect to this test. That is it! It is best to conduct this test when indoors or in medium/low ambient light to be extra cautious.

Coming to your questions one by one:

I agree with everything you've said. But!


None of the Apple LCDs have this issue, iPads/iPhones whatever. At any brightness level, 100% or otherwise. With AB on or off, the brightness intensity is the same. So I agree here.

Apple OLEDs are brighter with AB off when brightness is 100% assuming ambient light isn't super high. So I agree here.

"12 has same brightness like 11 in max brightness when is autobrightness off or if it is on in bright enviroment." - No idea and no comments about this. I have no idea here.

"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." I agree here but my point is different and my test is different. Read below.

Read carefully:

When at 100% brightness, yes brightness level will increase. So do the test closer to 50% or so. And there shouldn't be a change in the level of brightness (just like your 11) unless your OLED iPhone is defective.

So I do agree with everything you've said. But you've not done the test I asked you to (because it can't be done at 100% ever).

I did the test on my Mini and it did exhibit this behavior. Brightness significantly increased after 5 seconds on 50 and 100 % brightness.

Two questions:

1. I also experience an issue where True Tone will sometimes not adapt to ambient lighting conditions. This is only fixed by a reboot after which it works fine again for a while. Do you think this may be related?

2. What's the best course of action? Ask for a replacement or send it back and buy a new one?

1. Perhaps. But no personal experience in this regard. I do know the issue is related to Ambient Light Sensor as my local Apple genius confirmed as well I think.

2. I would suggest buy a new one rather than go to Apple to explain this because they'll have no idea what you're talking about.

yes I did experience lack of brightness on my iPhone 12, one of the reasons I returned it for the Max which is much brighter for whatever reason, very happy!

Can you please do the test on your Max for all of us? And of course only at 50% brightness or so? Not at 100% pls!
