1. A drug delivery device for delivering a medicament, the drug delivery device comprising:
a housing arranged to contain a container;
a drive component arranged within the housing of the drug delivery device and configured to move a piston of the container to dispense medicament from the container during a medicament delivery process; and
a receiver coil,
wherein the receiver coil is arranged to receive energy by electromagnetic induction from a transmitter coil of an external device when the external device is brought into proximity with the drug delivery device during an induction process,
wherein the drug delivery device is configured to perform the medicament delivery process while the external device is separated from the drug delivery device,
wherein at least a portion of the energy received by the receiver coil is converted by the receiver coil itself to heat energy at the receiver coil, and
wherein the receiver coil is arranged in the drug delivery device to transfer the heat energy to the container to heat medicament contained in the container.
