Ed, Turning auto brightness on and off was moved into Accessibility Settings although I don’t for the life of me know why Apple did this, according to my logic it is much more appropriate under Display and Brightness in the main Settings where it used to be. Anyhow, open Accessibility Settings, you are looking for “Display Accommodations”, it’s the fourth item from the top after Voiceover, Zoom and Magnifier.
As for brightness dropping to 0% when auto brightness is enabled and screen curtain is on this does seem to be the case although when I first tried this it didn’t seem to be so. When I first toggled screen curtain on and checked it still read the same value as before, but once I locked my phone and then unlocked it it was reading as 0% so it seems that if you turn on screen curtain the phone first has to lock and then as long as you keep screen curtain on when you unlock it the screen brightness is indeed at 0%. Regards, Sieghard turn auto brightness off and then manually set your brightness to 0% or 5% if you want just a bit of backlighting. Also, just as a little tip which I think many of us forget, when you can’t find a particular setting but pretty much know a word from it’s title, just try the search field at the top of the main settings screen. If you type either “auto” or “brightness” or even “bright” the setting for adjusting auto brightness shows up in the list of matches. It even reads the settings group where you find that setting. Now, here is an interesting item: Auto Brightness exists twice, once in General > Accessibility > Magnifier and also General > Accessibility > Display Accommodation. If you tap on the item in the search results it does take you to the Accessibility Settings, but interestingly enough not straight into Display Accommodations. When I checked Magnifier the setting for Auto Brightness there was turned off on my phone although it’s turned on in Display Accommodations. I assume maybe Apple moved it to Accessibility since you can control it separately for when you use the phone normally and when you turn on magnifier?

Hi Feliciano, I could not find the auto brightness in IOS 11. Could you please tell me where it is located. Also how do you know what you said in your email below is correct?

Hi, with iOS 11, if screen curtain and auto brightness is enabled. Brightness goes to 0%. With that said, you will conserve battery power.

The display elements are not turned off but just turned to black. On OLED screens such as with the iPhone X, a black screen turnes off the diodes.
