Dark Mode on iPhone and iPad provides a system-wide dark theme that optimizes the display for low-light environments. It reduces eye strain by switching the interface to darker tones, which are easier to look at in dim conditions. The mode also helps reduce the impact of blue light exposure, which can interfere with sleep, making it a practical option for nighttime use.
On devices with OLED screens, such as the iPhone X and newer, Dark Mode can extend battery life. OLED technology turns off individual pixels when displaying black, so the darker the display, the less power is used. This makes Dark Mode a useful feature for users who need to maximize battery performance.
Dark Mode is compatible with many third-party apps, syncing their appearance with the system setting. By enabling Dark Mode, you ensure a unified look across your device, including supported apps. This allows for a consistent visual experience when using your iPhone or iPad.
