1. A method of an electronic device comprising:

  • sensing an ambient temperature of the electronic device;

    determining whether the sensed ambient temperature is greater than a previously stored reference temperature;

    when the sensed ambient temperature is determined to be greater than the previously stored reference temperature, determining a previously stored high power level for a flash device;

    when the sensed ambient temperature is determined to be less than the reference temperature, selecting one of a plurality of pre-stored power levels in which each power level is associated with a different temperature value;

    operating the flash device at the determined power level to provide light;

    sensing a temperature of a battery of the electronic device; and

    shutting down a component of the electronic device when the sensed temperature of the battery is below a minimum value.
