Abstract: A method for determining natural illumination duration and an electronic device are provided, to more accurately determine a scenario in which a user is located and effectively determine natural illumination duration, to help the user improve vision. The method is applied to an electronic device having a display screen and includes: determining a current scenario based on a preset reference factor (S901), where the preset reference factor includes any one or more of ultraviolet intensity, illumination intensity, and locating signal strength; and counting current natural illumination duration towards cumulative natural illumination duration if the current scenario is a preset scenario (S902), where the preset scenario includes any one or more of an outdoor scenario, an indoor near-window scenario, and an outdoor blocked scenario.
