The feature allows users on Apple’s mobile operating system to alter the application’s visual theme from a light interface to a darker color palette. This adjustment primarily affects the background and text colors within the application, shifting towards darker shades for the background and lighter shades for the text. The result is a lower contrast display in comparison to the standard default theme.
The availability of this display setting offers several advantages. Users may experience reduced eye strain, particularly in low-light environments. Some individuals also find the darker interface aesthetically pleasing or conducive to extended usage. Furthermore, on devices equipped with OLED screens, the darker theme may contribute to lower power consumption, potentially extending battery life.
