Claim 4:
5. A battery-operated hair dryer, comprising:
a heating element positioned within an air flow channel, wherein the heating element includes first and second infrared bulbs; and
control circuitry coupled to the heating element and powered by at least one battery, the control circuit having an algorithm configured to determine the battery state-of-charge in real-time, calculate the remaining battery life before depletion, and determine a power mode setting to alter the power to the heating element to maximize the remaining battery life, and alter the power to the heating element for the power mode setting;
wherein the wherein the power mode setting includes pulsing the power to the first and second infrared bulbs out of phase at different times.
