Why my iPhone sometimes change screen brightness automatically?
I am all settings relating to brightness turned off (auto brightness, True Tone, night shift, automatic light and bright mode.)
iPhone 11 Pro
When your iPhone is in Low Power Mode, it may reduce the screen brightness to conserve battery life. Low Power Mode is typically activated when your battery level is low, but you can also enable it manually. To disable Low Power Mode, go to "Settings," then "Battery," and turn off the toggle for "Low Power Mode."
