1. A method to improve battery life of a portable electronic device, comprising:

  • receiving, by a sensor in a receiver, a plurality of sound waves at a pocket of energy, the plurality of sound waves wirelessly transmitted from a transmitter to form the pocket of energy, wherein the sensor converts the received plurality of sound waves to an alternating current;

    converting, by a rectifier of the receiver, the alternating current into a direct current for charging an auxiliary power supply of an electronic device that is coupled with the receiver;

    while the auxiliary power supply is being charged using the direct current;

    providing power to the electronic device using a primary power supply, distinct from the auxiliary power supply; and

    determining whether the auxiliary power supply is sufficiently charged to power the electronic device; and

    in accordance with determining that the auxiliary power supply is sufficiently charged to power the electronic device;

    providing power to the electronic device using the auxiliary power supply and ceasing to provide power to the electronic device using the primary supply.
