1. An aerosol generation device comprising an indicator and a controller connectable to a battery and a heater, the heater configurable to aerosolise a unit of aerosol generating material in an aerosolisation session and the battery configurable to provide power to the heater for one or more aerosolisation sessions, wherein the controller is configured to:
measure a charge level of the battery;
determine whether the measured charge level is sufficient for only a predetermined number N of aerosolisation sessions by the heater; and
indicate, using the indicator in a first manner, when the measured charge level is sufficient for only N aerosolisation sessions by the heater,
wherein, when determining whether the measured charge level is sufficient for only N aerosolisation sessions by the heater, the controller is further configured to:
compare the measured charge level to a first predetermined charge level and a second predetermined charge level, wherein the first predetermined charge level corresponds to the battery having a charge level insufficient for N+1 aerosolisation sessions, and the second predetermined charge level corresponds to the battery having a charge level sufficient for N aerosolisation sessions; and
determine that the measured charge level is sufficient for only N aerosolisation sessions when the measured charge level is less than the first predetermined charge level and greater than or equal to the second predetermined charge level.
