Display and appearance
Brightness
Most people call this how bright the screen is.
The brightness slider sets the base level of the display, and everything else the phone does adjusts around it.
This setting is present on your iPhone.
- We have this path on file but have not yet confirmed it against an official source.
Where to find it - iOS 10 and later

What it does
The slider in Settings and in Control Centre set the same value. Auto-Brightness then moves around your chosen level rather than ignoring it.

Questions people actually ask
- Why is my screen so dark even at full brightness?
- Reduce White Point, a Zoom filter, heat, or Low Power Mode. Check Accessibility first.
If it is not working
- If the slider will not go high enough, check Reduce White Point under Accessibility, which caps the maximum.
- Low Power Mode and high temperature both cap brightness.
- Zoom with a low display filter can also darken the screen beyond the slider.
