Abstract: Circuitry in the electronic device may use a plurality of magnetic sensors to detect an alternating current signal transmitted by the wireless charger and/or to detect a magnetic field generated by one or more magnets in the wireless charger. The circuitry may determine a position of the wireless charger relative to a wireless power transfer coil in the electronic device and provide feedback to guide users in attaching the wireless charger to the correct position on the electronic device, including such as visual indications on a device display.
