A power supply system for a wireless electronic device comprising: a primary and secondary power source operatively coupled to the electronic device and a controller, the controller being configured to control a rate of energy flow from the primary power source to maintain predetermined energy flow rates such that an available capacity of the primary power source is increased, wherein the primary power source is configured to charge the secondary power source via the controller, which switches an extraction of energy from the primary power source between first and second the predetermined energy flow rates during a charging operation, and wherein: the first predetermined flow rate is an optimized energy transfer flow rate; and the second predetermined flow rate is a fast charge flow rate; wherein during periods of wireless information transfer from the electronic device the controller is configured to switch to the fast charge flow rate such that the secondary power source is quickly recharged.
