The automatic adjustment of display illumination, a feature available on Apple’s mobile operating system, specifically version 12, dynamically adapts screen luminosity based on ambient lighting conditions. For instance, the system dims the display in darker environments to reduce eye strain and increases brightness in brighter settings for improved visibility.
This functionality provides several advantages, including optimized battery consumption by reducing unnecessary screen illumination. Furthermore, it enhances user comfort by mitigating potential visual fatigue caused by excessively bright or dim screens. Historically, its introduction represented a significant step towards improved user experience and device energy efficiency.
