Abstract: A method for prompting charging position includes acquiring a value of a first charging parameter through a first induction coil of an electronic device, determining whether a prompt message needs to be sent out based on the value of the first charging parameter, and after outputting the prompt message is determined, sending out the prompt message through an output unit of the electronic device to guide a user to move the electronic device to change a relative position between the electronic device and a wireless charging device from a first relative position to a second relative position. Further, the electric power obtained by and converted through the first induction coil when the relative position is the first relative position is smaller than the electric power obtained by and converted through the first induction coil when the relative position is the second relative position.

Abstract: A charging method is provided for an electronic device. The charging method includes monitoring a current capacity of a battery coupled to a first electronic device to obtain a current level of remaining power in the battery and receiving a control command. The control command is used to instruct the first electronic device to enable a charging module and then to use the charging module to charge a second electronic device based on the current level of the remaining power in the battery. The charging method also includes receiving an operation command. In response to the operation command, the charging method further includes determining a first capacity of the battery based on the current level of the remaining power in the battery, and then controlling the charging module to provide electric power for the second electronic device based on the first capacity of the battery.
