Abstract: A method of operating an aerosol-generating device is provided, the device including a power supply to supply power to generate the aerosol, and a controller, the method including: monitoring a parameter indicative of aerosol generation during operation of the device; and analysing the monitored parameter to identify a user puff defined by a puff start and end, the analysing including calculating first and second characteristics of the monitored parameter, and analysing the first and the second characteristics to determine the puff start and end, the parameter indicative of aerosol generation representing power supplied by the power supply, the first and the second characteristics respectively being a first and a second moving average value of the monitored parameter computed on a first and a second time window having a first and a second time window duration, the second time window duration being different from the first time window duration.

Abstract: An aerosol-generating device is provided, including: an electrical heating arrangement configured to heat an aerosol-forming substrate in order to generate an aerosol; at least one of a user switch to enable a user to initiate a use pause of the device, and at least one sensor to output a sensor signal indicative of the device being in use by the user or in the use pause; and a controller to generate a pause signal in response to the sensor signal indicating that the device is in the use pause and/or in response to the user initiating the use pause of the device via the user switch, the heating arrangement being further configured to heat the substrate at a first temperature level in an aerosol-releasing mode, and in response to the pause signal to heat the substrate at a second temperature level below the first temperature level in a pause mode.
