Staring at a bright white screen in a dark room strains your eyes, disrupts sleep-inducing melatonin production, and rapidly drains battery on OLED displays. Manually toggling between light and dark themes multiple times a day is tedious.

Telegram provides one of the most flexible dark-mode automation engines in the mobile industry with three distinct operational modes:

• Match System: Automatically aligns Telegram's appearance with your smartphone or desktop OS theme.
• Scheduled: Automatically turns on dark mode at sunset and returns to day mode at sunrise, or according to your custom defined schedule (e.g., 22:00 to 07:00).
• Automatic (Ambient Sensor): Uses your device's ambient light sensor to trigger dark mode whenever ambient room lighting drops below a calibrated brightness threshold.

On smartphones equipped with AMOLED displays (such as modern iPhones and Samsung Galaxy devices), pure black pixels (#000000) completely turn off sub-pixels rather than illuminating them. Selecting the Night (OLED) theme in Auto-Night Mode saves measurable battery consumption during late-night messaging marathons while eliminating screen glare.
