The application relates to a stimulation device with power conservation functionality. In implantable devices, power supplies may be limited. Replenishing these power supplies may require costly surgery or periodic recharging depending on the model. A method may be implemented that skips or drops periodic pulses without apparently changing the frequency of the pulses. In this manner, the dropped pulses may be undetected by the patient. On the other hand, the dropped pulse represents power savings. Dropping one in ten pulses may lead to a 10% energy savings. The stimulation device may implement the method with one or more counters implemented in hardware or software.
