Optional Terminal Charging Method, Graphical User Interface, and Electronic Device

An electronic device, where after the electronic device is coupled to a charging device, the electronic device is configured to obtain a current time, charge the battery in a first mode in response to the current time is in a first time period, in response to the current time is in a second time period and after the battery level is less than a preset threshold, charging the battery in the first mode; in response to the current time is in a second time period and after the battery level is greater than or equal to the preset threshold, charging the battery in a second mode, wherein the second time period is after the first time period is subtracted from a whole day time period, and the preset threshold is less than a battery level when the battery is fully charged.
