Aerosol-generating device

An aerosol-generating device, comprising:

• control circuitry and an energy storage configured to supply electrical energy to the control circuitry for generating aerosol from an aerosol-generating article,
• wherein the control circuitry is configured to:
• determine a storage status of the energy storage indicative of at least one an amount of electrical energy currently stored and an amount of electrical energy currently storable in the energy storage,
• evaluate the determined storage status with respect to at least one threshold value associated with at least one device function of the aerosol-generating device, wherein the at least one threshold value is adjustable,
• enable or disable, based on the evaluation, the at least one device function,
• compute, based on historic data indicative of an operation of the aerosol-generating device to generate aerosol, an amount of energy used in one or more usage sessions, and
• adjust the at least one threshold value based on the determined amount of energy used in the one or more usage sessions.
