Apparatus and method for extending implant life using a dual power scheme

A device for the treatment of sleep disordered breathing, the device comprising:

• a housing configured for temporary affixation on at least one of a neck and a head of a subject;
• and
• at least one processor associated with the housing and configured for electrical communication with a power source;
• and
• an antenna associated with the at least one processor;
• the at least one processor being configured to:
• communicate with an implant circuit in a region including at least one of the neck, an underside of a chin, and the head of the subject in a location proximate a hypoglossal nerve,
• cause the implant circuit to receive power in a first power mode and in a second power mode, wherein a first level of power delivered in the first power mode is less than a second level of power delivered in the second power mode, and wherein during a therapy period, power delivery in the first power mode occurs over a total time that is greater than 50% of the therapy period.
