Alignment coils of wireless charging for electronic device

An electronic device, comprising:

• a processor;
• a power supply module operatively coupled to the processor;
• a receiving antenna operatively coupled to the power supply module, wherein the receiving antenna cooperates with a transmitting antenna of a wireless charger to charge the power supply module wirelessly;
• an inductor arranged with respect to the receiving antenna, wherein the inductor comprises a first wire and a second wire, disposed opposite to each other, through which a first induced voltage and a second induced voltage are generated respectively, wherein the first wire is different from and unconnected to the second wire;
• a comparator for comparing the first and second induced voltages;
• a memory operatively coupled to the processor and that stores instructions executable by the processor to determine whether the receiving antenna is aligned with respect to the transmitting antenna of the wireless charger based upon the comparison of the first and second induced voltages;
• wherein the first wire encircles a first region and the second wire encircles a second region, the first region and the second region having the same area irrespective of whether the first region and the second region are a matching shape;
• wherein the electronic device is a handheld electronic device.
