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