iPhone 16 pro screen doesn’t dim to 1 nit

In settings go to accessibility->display and text size->reduce white point

you can also add it to control center by holding on an empty space, tapping add control and all the way at the bottom is the vision accessibility section with the reduce white point toggle. Not sure if it takes it all the way down to 1 nit but it’s noticeably darker.

With all due respect, I am beginning to suspect that you are misunderstanding each other. I am clearly writing that I am checking the settings and behavior of the phone that I am holding in my hand, and you are suggesting that someone else is changing the settings - what sense does that make in the context of what I am describing? Unfortunately, store employees (in Poland) are very incompetent in terms of knowledge about devices and software. Some do not even know what Nit is. I have encountered this in an authorized service. So asking questions other than the price of the device is often a waste of time.

Authorized Apple Reseller. How do I know? Because I checked desired the display setting in Settings app on these iPhones.

Furthermore, lowering the white point also lowers the maximum brightness and those phones shine at full brightness at the maximum setting.

The ambient light is very high, as usual in a store.I am comparing my device with the iPhone 16 Pro & Pro Max exhibition device(s). Mine behaves differently in terms of screen brightness setting, similar to other users who have reported this phenomenon. It is therefore possible to suspect that I have a device that does not match the manufacturer's description (and the phones at the exhibition can be considered as such), which should lead to some explanations. In my opinion, this is not right and I will pursue this topic.

But I just wrote that the ones at the exhibition can dim the screen to 1 nit, and users (including me) do not have this option available without turning on the white point reduction function.

Just as a general point of reference for future visitors to this thread. When I turn down Auto Brightness at this path,

Now you are one nit of brightness.

Don’t do this in bright light as you will not be able to view your screen to reset the settings. You’ve been warned.

I have been following the discussion and the one thing which comes to my mind, at least, is why it matters if an iPhone goes all the way down to one nit? It would make the screen brightness so low as to render it, at least to me, not pleasant to view.

Exhibition models do not have this function enabled (Reduce White Point), but they can still reduce the display to 1 nit. Can this be considered an attempt at customer manipulation?

No, of course it's not. Maybe Apple just doesn't want customers to look at iPhone screens which are too dim, while they are on display.

Not all features can be enabled at the same time. Some features are mutually exclusive, meaning if one setting is enabled, another must be disabled. This is just common sense, not customer manipulation.

With all due respect. You’re talking about a product that is on exhibition at a store that Apple is directly responsible for. If you want to talk about a personal device, then don’t confuse the issue with iPhones on display at a retailer.

So, which is it, your personal device or a device on display (exhibition)?

OK, it’s your personal device. What are the ambient light levels where you are currently viewing your iPhone screen? Have you turned off Auto Brightness in Accessibility in your Settings App on your iPhone?

"With all due respect. You’re talking about a product that is on exhibition at a store that Apple is directly responsible for. If you want to talk about a personal device, then don’t confuse the issue with iPhones on display at a retailer."

And what should I compare my phone to? To a cup of coffee in the store next door? With all due respect.

Of course I will compare it to exhibition phones of the same model. This is so obvious that I'm surprised I even have to explain it.

"You didn’t answer my question. Is Auto Brightness turned off in Accessibility? There are two place Auto Brightness must be turned off".

I tested both variants. On and off. In both cases, the brightness of the screen on my iPhone presented different parameters than the exhibition iPhones.

I can’t see what you’re seeing, but with the limited information I have, I’d suggest you take your device to an Apple Store for inspection. Unfortunately, there aren’t any in Poland. Have you talked to Apple Support about this issue?
