Abstract

See full text

An electronic vaping device includes a liquid storage portion, an electric heater and electronic circuitry. The liquid storage portion is configured to store liquid vapor-forming substrate. The electric heater includes at least one heating element, the at least one heating element configured to heat the liquid vapor-forming substrate. The electronic circuitry is configured to self-activate the electric heater for a first time interval during a period of inactivity of the electric heater to determine depletion of the liquid vapor-forming substrate based on a relationship between a power applied to the at least one heating element and a resulting temperature change of the at least one heating element.
