Actually you can adjust your brightness in control center.

Even setting brightness to zero won’t really make any dent in the battery. If

impact on battery performance.
If someone disagrees, they should test it. Use your phone normally with and
without, and see what, difference, if any, you observe.

It does if it automatically sets brightness to 0%. This way you can turn auto
brightness on and then turn the screen curtain on. Your brightness will be at
0% despite the auto brightness and if you want a sighted person to look at the
phone all you have to do is turn screen curtain off and the phone will revert
to whatever auto brightness setting is appropriate.
If you turn auto brightness of and manually set brightness to 0% then you have
to go into Settings > Display and Brightness and turn it up which involves a
lot more steps than a 3-finger triple tap.

In any case, unless the iPhone is an iPhone X, the curtain does not conserve
battery.

That's probably because only blind persons would want to turn brightness very
low or off completely.

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?
Regards,
Sieghard

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.

It is correct. this is because on LCD screens, the same amount of
energy is used to project black on the screen as white or other
colors. 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.

Hi All,
I know this has been discuss way back when. To my recollection I remember
it
being said that having the screen curtain turned on does not save battery
power. Can anyone share any information on this as to whether this is
correct or not.
