An electronic device is configured to perform a power cycle reset in response to a change in charging power applied to the device. The device includes an electrical load with a microprocessor, a battery, a charging circuit that receives power from an external power source and uses the received power to charge the battery, and a control circuit that regulates the power cycle reset operation. The power supply circuit selectively uses the battery to power the device by coupling the load to a power supply path and discharges the load by coupling the load to a discharge path. The control circuit receives, from the charging circuit, an indication of a change in power applied to the charging circuit and responsively generates a control signal and applies the control signal to the power supply circuit, which causes the power supply circuit to temporarily couple the load to the discharge path.
