1. An electronic vaping device comprising:
a heating element;
a power source configured to apply a voltage to the heating element;
a sensor configured to sense airflow; and
a processor configured to,
control the power source to apply a first voltage to the heating element for at least a first time interval in response to the sensed airflow regardless of whether the sensed airflow stops before expiration of the first time interval,
control the power source to apply a second voltage to the heating element based on the sensed airflow, and stop application of the second voltage to the heating element in response to cessation of the sensed airflow, the first voltage being greater than the second voltage, and
control the power source to apply a third voltage to the heating element based on the sensed airflow, and stop application of the third voltage to the heating element in response to cessation of the sensed airflow, the second voltage being greater than the third voltage, and the third voltage being a non-zero voltage.
