A charging control method, an electronic device, and a charging control system. According to the charging control method, when a first electronic device is in a power-off state, an embedded controller is controlled to be powered off. When a second USB port of a second electronic device is connected to a first USB port of the first electronic device, the embedded controller is woken up by using a first power supply signal that is input through the second USB port, the embedded controller obtains device information of the second electronic device, and then the embedded controller controls, based on the device information, a first battery of the first electronic device to charge the second electronic device. According to the method, the first electronic device can charge the second electronic device when being in the power-off state.

This application provides a screen projection processing method and an electronic device, and relates to the field of communication technologies. By using the solution of this application, when a screen projection source device performs screen projection to a screen projection target device through a screen projection application, if the screen projection application is closed abnormally, a state of a virtual display driver is set to a disabled state. In this way, the virtual display driver will no longer create a virtual display, so that the screen projection source device cannot capture an image used for screen projection in a case that no virtual display exists. Therefore, in a non-screen projection scenario after the screen projection application is restarted, a display screen of the screen projection source device performs display normally without a black screen phenomenon.

This application provides a data sharing method and apparatus relating to the field of data communications technologies. In the method, a cloud device may select a target device from a first device group through screening based on a data sharing policy and received status information of at least one device in the first device group. Then, the cloud device may indicate the target device to send data associated with the data sharing policy for a first cloud account to at least one device in a second device group. The first cloud account is used to log in to a device in the first device group, a second cloud account is used to log in to a device in the second device group, and the cloud device stores the data sharing policy for the first cloud account and an association relationship between the first cloud account and the second cloud account.

A scheduling and processing method and apparatus for a wireless fidelity (WiFi) station (STA), which resolve a prior-art problem that when multiple STAs are connected to WiFi by means of one access point (AP), due to bandwidth contention, once a STA sensitive to a radio frequency signal is connected to the WiFi, the STA may occupy almost all bandwidth for data exchange, causing a decrease in quality of service of data transmission of the other STAs. The method includes the following steps: acquiring network connection information, within a predetermined time, of STAs that are connected to a WiFi network by means of an AP; sorting the network connection information of the STAs in accordance with priorities according to a predetermined algorithm, to obtain a level list of the STAs; and scheduling and processing to-be-processed data of a corresponding STA according to the level list.
