Abstract

The invention discloses a wireless charging method, device and apparatus and a storage medium, and relates to the technical field of mobile terminals. The method comprises the steps that when a mobileterminal detects that the mobile terminal is placed on a wireless charging tray for wireless charging, the magnetic field intensity during current wireless charging is obtained; the mobile terminal inquires whether the optimal placement position corresponding to the magnetic field intensity is stored or not from a preset mapping table according to the magnetic field intensity; and when querying that the optimal placement position corresponding to the magnetic field intensity is not stored in the preset mapping table, the mobile terminal generates an alarm instruction for prompting a user to adjust the placement position, and sends an alarm prompt according to the alarm instruction.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a wireless charging method, device, equipment and storage medium. Background technique [0002] When charging a terminal with wireless charging function, it needs to be placed on the wireless charging tray. At present, wireless charging usually uses electromagnetic induction technology. The wireless charging tray is used as the energy transmitter, and the terminal is used as the energy receiver. Both of them have coils. The material and size of the coils are limited by cost and space. There is a certain efficiency conversion in the process of energy transfer. When the material and size of the coil remain unchanged, the relative position of the two coils will largely determine the efficiency of electromagnetic induction, that is, the efficiency of wireless charging. In the background technology, when calculating the wireless charging efficiency, it is necessary t...
