Screen dimming in outdoor sunlight is primarily caused by Thermal Throttling. When ambient temperatures are high and direct sunlight hits the OLED panel, the CPU and display generate significant heat. To protect internal hardware components from thermal damage, iOS automatically limits screen peak brightness regardless of your slider settings.
