Provided are an electronic device and a wireless charging method and apparatus for an electronic device. In the wireless charging method, an environmental parameter transmitted by a wireless charging device is detected (S102); and a receiving antenna board within an electronic device is moved to a designated position according to the environmental parameter, wherein charging efficiency for charging the electronic device at the designated position is higher than charging efficiency for charging the electronic device at other positions (S104). The problems of wasting time and poor user experience caused by adjusting back and forth the electronic device in the process of wireless charging are solved. Free positioning of the antenna can be implemented, and time required by matching the electronic device and a wireless power supply device in the process of wireless charging can be greatly reduced.
