SYSTEM AND METHOD OF EXTENDING USEFUL LIFE OF POWER SUPPLY
First Claim
1. A method of internally heating a power supply of a portable electronic device in reduced temperatures comprising:
- positioning an antenna of the portable electronic device proximate to the power supply;
receiving a temperature signal that is a function of a temperature of the power supply;
determining whether the temperature is within a reduced operating-temperature range;
sending current through the antenna in response to the temperature being within the reduced operating-temperature range; and
terminating the “
current sending”
operation of the portable electronic device when the temperature is outside the reduced operating-temperature range.

Abstract
A method of internally heating a power supply of an electronic device in reduced temperatures is provided. The method comprises positioning an antenna of the electronic device proximate to the power supply and receiving a “temperature” signal that is a function of a temperature of the power supply. When it is determined that the temperature is within a reduced operating-temperature range, the temperature is elevated and the equivalent series resistance (ESR) of the power supply is correspondingly reduced by actively sending current through the antenna. The “current sending” operation is reduced when the temperature of the portable electronic device is outside the reduced operating-temperature range.

10. A portable electronic device comprising:
-
a processor electrically coupled to a temperature sensor; a power supply electrically coupled to the processor and temperature sensor; an antenna positioned proximate to the power supply; and a power-management sub-system controlled by the processor, the processor configured to receive a temperature signal that is a function of a temperature of the power supply, configured to determine whether the temperature is within a reduced operating-temperature range, and configured to control the power-management sub-system to elevate the temperature and correspondingly reduce equivalent series resistance (ESR) of the power supply. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computer-readable medium having computer-readable instructions stored on the computer-readable medium for execution of the computer-readable instructions by a processor to internally heat a power supply of a portable electronic device in reduced temperatures, the computer-readable instructions comprising:
-
receiving a temperature signal that is a function of a temperature of the power supply; determining whether the temperature is within a reduced operating-temperature range; elevating the temperature and correspondingly reducing equivalent series resistance (ESR) of the power supply by actively sending current through an antenna in response to the temperature being within the reduced operating-temperature range; and terminating the “
current sending”
operation of the portable electronic device when the temperature is outside the reduced operating-temperature range.
