Abstract: An aerosol-generating device is provided, including: a cavity configured to receive an aerosol-forming substrate; an electrical heater to heat the substrate when received within the cavity; a power supply; and a controller to control a supply of power to the heater during a first time period and a subsequent second time period, determine an initial temperature of the heater, and to determine a rate of increase in temperature of the heater during the first time period by determining a time taken for a temperature of the heater to increase from a first to a second predetermined temperature during the first time period, and adjust the supply of power to the heater during the second time period based on the initial temperature of the heater and based on the determined rate of increase in temperature of the heater during the first time period.

Abstract: A system is provided, including: an aerosol-generating device and/or a charging device associated with an aerosol-generating device; a near-field communication module including a nonvolatile memory; and a controller configured to receive an indication of an error occurrence and to update an error data log stored in the nonvolatile memory by storing an error data entry associated with the error occurrence to the error data log, the error data entry being configured to be read by an external device even when the aerosol-generating device and/or the charging device including the near-field communication module is not powered. A method for maintaining error data on an aerosol-generating device and/or a charging device associated with an aerosol-generating device is also provided. A method for recovery of error data from an aerosol-generating device and/or a charging device associated with an aerosol-generating device is also provided.
