1. A wirelessly powered device, comprising:

  • a device positioning aid processor configured to;

    place at least one component into a high electrical current consumption mode; and

    receive, based on placing the at least one component into a high electrical current consumption mode, a measured value from an electrical current measurement device, the measured value indicating an amount of an electrical current induced in a receiving coil adapted to inductively couple to a transmission coil external to the wirelessly powered device, where at least part of the electrical current induced in the receiving coil is provided to the at least one component; and

    a charging device proximity indicator, communicatively coupled to the device positioning aid processor, the charging device proximity indicator configured to provide, based on the measured value indicating the amount of electrical current, an indication corresponding to an amount of distance from the receiving coil to the transmission coil based on the amount of electrical current.
