1. A method for wireless power receipt, the method comprising:

  • transmitting, by a communication device of an electronic device that is coupled with a receiver, to a communication device of a transmitter a communication signal indicating (i) a power requirement of the electronic device and (ii) a position of the receiver relative to the transmitter, wherein the electronic device includes a primary power supply and an auxiliary power supply that is distinct from the primary power supply;

    receiving, by an antenna of the receiver, one or more power waves forming constructive interference patterns defining a pocket of energy, wherein the one or more power waves are transmitted from a plurality of antennas of the transmitter to converge at a location associated with the position of the receiver to form the constructive interference patterns defining the pocket of energy and wherein the receiver receives the one or more power waves from the transmitter as the communication signal indicates the position of the receiver relative to the transmitter,in conjunction with receiving the one or more power waves, determining whether the electronic device is in a sleep mode;

    in accordance with a determination that the electronic device is in the sleep mode, exiting the sleep mode;

    after exiting the sleep mode;

    converting, by the receiver, the one or more power waves forming constructive interference patterns defining the pocket of energy to electrical power that is used to charge the auxiliary power supply; and

    in accordance with a determination that the auxiliary power supply is sufficiently charged to power the electronic device, providing power to the electronic device using the charged auxiliary power supply.
