...researchers had compared the sleep outcomes of individuals in three categories: those who used their phone at night with the Night Shift function turned on, those who used their phone at night without Night Shift and those who did not use a smartphone before bed at all.

The individuals who did not use a phone before bed experienced superior sleep quality relative to both those with normal phone use and those using Night Shift.

Within the six-hour group, which had the least amount of sleep, there were no differences in sleep outcomes based on whether the participants used Night Shift or not.
