What is Night Shift on iPhone?

As we know, blue light emitted from electronic devices is a major cause of eye strain, sleep quality degradation, and melatonin suppression, a crucial hormone. Therefore, activating Night Shift on iPhone is essential to minimize the harmful effects of blue light from electronic screens, promoting better sleep and overall health.

Note that this mode is currently only available on Apple devices running iOS 9.3 and later. When enabled, the screen automatically adjusts its color temperature, producing warmer tones while reducing the intensity of blue light. Additionally, users can conveniently customize its activation schedule based on a personal timetable or the sunrise and sunset cycle.
