Explanation

Power saving mode is the most likely cause. When a device's battery drops below a configured threshold, power saving mode activates automatically and aggressively dims the screen to conserve battery - even without the user changing any settings. Auto-brightness (C) adjusts based on ambient light sensors and would not cause unexplained, frequent dimming. A faulty backlight (A) would typically cause permanent or random flickering, not consistent dimming tied to usage patterns. High contrast mode (B) alters color schemes but does not dim the screen.
