The ability to enable a darkened user interface on the Instagram application for Apple mobile devices running a specific older operating system is the central topic. This functionality addresses users who prefer a darker color palette on their screens, especially in low-light conditions. An example of its use is a user with an iPhone 6 running iOS 12 who wishes to browse Instagram at night without the screen appearing overly bright.
Implementing a darker theme on mobile applications offers several advantages. It can reduce eye strain, conserve battery life on devices with OLED screens, and provide a more aesthetically pleasing experience for some individuals. Prior to widespread system-wide dark mode implementation by Apple, users often sought alternative methods to achieve this effect within individual applications, highlighting the user demand for this feature.
