Abstract
The disclosure relates to a wireless charging system, a determining method and device for a charging region, and an electronic device. The wireless charging system can include a wireless charging base and an electronic device. The wireless charging base includes a cylindrical magnet disposed axially along a thickness of the wireless charging base. The electronic device includes a charging coil component, a compass sensor which is configured to detect magnetic field intensities of a magnetic field generated by the cylindrical magnet in a first direction and in a second direction. The first direction is an axial direction of the cylindrical magnet and is perpendicular to the second direction. The electronic device further includes a processor configured to determine, according to the magnetic field intensities in the first direction and in the second direction, a charging region formed by the cylindrical magnet and adapted to the charging coil component.
