- the processing unit 82 is further configured to: at the sending unit 83, send, to the first electronic device, at least one of charging state information of the electronic device, output power information of the electronic device, and remaining battery information of the electronic device.
- the electronic device receives a notification sent by the first electronic device when determining that the electronic device is a charging party, and starts an NFC wireless charging service of the electronic device according to the notification, to prepare for the first electronic device Charging; or, the electronic device receives a charging control message sent by the first electronic device when determining that the first electronic device is a charging party, to notify the electronic device to respond as a charged party.
- the two electronic devices can determine the charging party according to the charging reference message and automatically turn on the charging party's NFC wireless charging service, thereby making full use of more fragmentation.
- the time is charged for the peer electronic device, which avoids the time and labor caused by the user's active operation and improves the user experience.
- the disclosed electronic device can be implemented in other manners.
- the electronic device described above is merely illustrative.
- the division of the module or unit is only a logical function division.
- there may be another division manner for example, multiple units or components may be combined. Either can be integrated into another system, or some features can be ignored, or not executed.
- the coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection through some interface, device or unit, and may be electrical, mechanical or otherwise.
- each functional unit in each embodiment of the present application may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.
