An apparatus and a method for an aerosol generating device is described, the apparatus including a control module and a charging controller. The charging controller is configured to control charging of a battery at a first charging rate in a first charging mode and to control charging of the battery at a second charging rate, lower than the first charging rate, in a second charging mode. The control module is configured to determine information relating to usage of the aerosol generating device. The charge controller is configured to operate in the first charging mode or the second charging mode depending, at least in part, on the information relating to the use of the aerosol generating device.

There is provided an aerosol provision system comprising a power source; an aerosol generating component; and, control circuitry, wherein the control circuitry is arranged to control the power source and the aerosol generating component to provide a selection between at least: a predetermined aerosolization profile; and a variable aerosolization period, to be applied to aerosol generating material.
