Aerosol generating system with self-activated electric heater

An electronic vaping device comprising:

• a reservoir configured to store pre-vapor formulation;
• an electric heater configured to heat pre-vapor formulation drawn from the reservoir;
• and
• electronic circuitry configured to
• self-activate the electric heater for a first time interval during an inactivity period after a threshold number of activations of the electric heater, each activation of the electric heater being in response to application of negative pressure to the electronic vaping device, and the inactivity period being a time period during which negative pressure is not applied to the electronic vaping device, and
• determine at least one characteristic of the electric heater during the first time interval, and
• determine whether to deactivate the electronic vaping device based on the at least one characteristic of the electric heater.
