General note: if your iPhone won't go dark enough at night even with night mode, look under Accessibility - Display & Text Size -> Reduce White Point. Set the sliding value to what's comfortable for you. Then scroll down the Accessibility settings page to Accessibility Shortcut. This sets what happens when you triple-click the power button. If you set this to Reduce White Point (RWP), it will turn on/off RWP while remembering the slider setting you selected. I find this invaluable when I wake up in the middle of the night and want to read for a bit without filling my eyes with light / risking waking anyone. (Edited for spelling)
