Abstract: This application relates to the field of electronic device technologies, and provides a camera module and an electronic device, to reduce a volume of the camera module while improving image stabilization performance of the camera module. The camera module includes an optical lens, a module circuit board, a photosensitive chip, and an actuator. The module circuit board is disposed on a light exit side of the optical lens and includes a fastening part, a moving part, and an elastic part. The moving part is elastically connected to the fastening part through the elastic part. The photosensitive chip is disposed on a side that is of the moving part and that faces the optical lens. The actuator includes a fastened clamping jaw, a movable clamping jaw, and a wire. The actuator drive the moving part to move relative to the fastening part when the length of the wire changes.

Abstract: Example charging methods are described. One example method includes determining that a second electronic device is wirelessly connected with a first electronic device. The first electronic device is charged using the second electronic device, in a wireless charging receiving mode of the first electronic device, when the second electronic device is a wireless charging cradle device. Charging current is provided to the second electronic device, in a wireless charging cradle mode of the first electronic device, when the second electronic device is a wireless charging receiving device. The first electronic device can be used both as a wireless charging receiving device to receive electric energy provided by a wireless charging cradle device, and as a wireless charging cradle device to provide charging current to a second electronic device.
