1. A method of controlling a heater of a non-nicotine e-vaping device, the non-nicotine e-vaping device including a removable container that stores a non-nicotine pre-vapor formulation, the method comprising:
detecting, from the removable container, power information indicating a first operating point and a second operating point, the power information including a plurality of operating points that correspond, respectively, to a plurality of coarse preference levels, the plurality of operating points including the first operating point and the second operating point;
receiving, via one or more touch sensors located on the non-nicotine e-vaping device, a selection of a coarse preference level from among the plurality of coarse preference levels;
selecting an operating point from among the plurality of operating points that corresponds to the selected coarse preference level as the second operating point; and
supplying power to the heater based on the detected power information by,
determining a first amount of power based on the first operating point,
supplying the first amount of power to the heater during a first operation mode of the heater,
determining a second amount of power based on the second operating point, and
supplying the second amount of power to the heater during a second operation mode of the heater,
the second amount of power being higher than the first amount of power.
