A control device of an aerosol generating device includes a main control unit, and is connectable to a battery and a heater coil. The main control unit is configured to carry out one or more execution loops, a first execution loop includes applying a first power output to the heater coil for a first number of steps, disabling the first power output and thereby switching off the heater coil in a second number of steps, measuring a first heater coil voltage of the heater coil in a third number of steps, pausing with the heater coil switched off for a fourth number of steps, and measuring a first off-load battery voltage of the battery in a fifth number of steps. The main control unit is further configured to calculate an updated power output based upon the first heater coil voltage and first off-load battery voltage.
