So many folks believe the auto-brightness level is too high on iPhones / iPads. Because perhaps you switched from Android to iPhone, or you feel the iOS 9 to iOS 10 upgrade is the reason for varying screen brightness.
For that reason, I recommend you to manually change the brightness level. You can go to extreme low through the Brightness settings available inside the iOS 10’s Settings.
But what if you want more? What if you want to reduce the brightness even further? You want to go to the lowest of the low?
In such cases, iOS 10 (and even earlier iOS) offers a hidden feature that reduces brightness to a new extreme level.
And it does exactly what you think:
It reduces the whitish color on your iPhones / iPads. Doing this converts the screen into what you see below:

To enable Reduce White Point:
Go to Settings -> General -> Accessibility -> Display Accommodations. Look for “Reduce White Points” and toggle the switch. (Green means the feature is enabled. Otherwise it is disabled).
