iPhone 16 pro screen doesn’t dim to 1 nit

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

iPhone > Settings > Display & Brightness > slide to the far left

iPhone > Settings > Accessibility > Display & Text Size > scroll to bottom > Auto Brightness > switch off, if already off, momentarily switch on then switch off again.

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 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"?

Yes, I wrote to Apple but no response so far.

"Writing to Apple is a long path forward. Why do you need 1 nit? That’s so dark, you can’t see it unless you’re in a coal mine and lights go out. It’s ridiculously dark".

This was one of the main reasons I went with the Pro. I often use my phone in dark environments and for me this is very important. If I can't set this without lowering the white point, then that's a cause for dissatisfaction for me.

I have my White Point setting off (no adjustment), and Auto Brightness in both settings to their minimum. I measured the brightness with one of my photographic light meters that measures Lux and converted to nits. The measure is very close. In my opinion, you should not have to adjust White Point, just leave is off.

I voiced the same concern and OP stated they use the iPhone in dark environments. Maybe doing astrophotography or something similar where night vision is extremely important. I suspect if your eyes are acclimated to the darkness, 1 lux is very usable, but it’s at the extreme of the vast majority of users.

ZKmusic understands the issue too. I don’t know if this should be innovation or what but my S21 and iPhone 16 at the lowest brightness settings are brightning same. 1 nit, you can call it a wise way of manipulation and making someone buy a product and understanding Samsung does the same but they do not mention it. Good luck finding a way, I usually reduce white since “1 nit” is a myth.

You can get to 1 nit, but it’s so dark, you can’t see the interface to adjust the controls. Please follow this path,

iPhone > Settings > Accessibility > Vision > Display & Text Size > Auto-Brightness > off

iPhone > Settings > Accessibility > Vision > Display & Text Size > Reduce White Point > 100% slider

iPhone > Control Center > Screen Brightness > reduce brightness to minimum.

If that’s not 1 nit I can’t imagine a dimmer screen and still being legible. I have a light meter that reads in Lux. I’d be happy to take a measurement.

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

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?

How do you know it’s not turned on? Where were viewing the devices on display, was it an Apple Store or third party retailer?

It could be customers playing with the settings. The only way to know is talk to the owner of the establishment. But that’s certainly not an Apple policy. I’d know. I’m a former Apple Store manager.

Writing to Apple is a long path forward. Why do you need 1 nit? That’s so dark, you can’t see it unless you’re in a coal mine and lights go out. It’s ridiculously dark.
