Many iPhone users want to reduce eye strain, save battery, or improve focus by turning their screen to black and white mode. However, finding and enabling this feature can be confusing without clear guidance. This article solves that problem by providing detailed steps to activate grayscale mode on your iPhone.
Black and white mode on iPhone is called Grayscale, an accessibility feature that removes color from the display. Developers and users use it to minimize distractions, test app color accessibility, or conserve battery on OLED screens. This guide covers how to turn it on, customize it, troubleshoot issues, and best practices for use.
What is black and white mode on iPhone?
Black and white mode on iPhone, officially known as Grayscale, is an accessibility setting that removes all colors from the display, showing only shades of gray. This mode helps users with color blindness, reduces visual clutter, and can lower eye strain in certain lighting conditions. It also helps developers test how their apps appear to users who rely on grayscale.
When enabled, all UI elements, images, and videos appear in black, white, and gray tones. This does not affect screenshots or photos saved outside the display. Grayscale mode is part of the iPhone's Accessibility settings, designed to make the device easier to use for people with visual impairments.
Using black and white mode can also extend battery life slightly on iPhones with OLED screens, as pixels displaying black consume less power. However, this effect is minor compared to other battery-saving methods.
