An authentication device or other type of low-power hand-held device comprises a processor, an external button alternately configurable in an unpressed state and a pressed state, and current drain mitigation circuitry coupled to the external button and a corresponding input of the processor. The current drain mitigation circuitry is configured to connect the input of the processor to a first potential when the external button is in the unpressed state and to connect the input of the processor to a second potential different than the first potential when the external button is in the pressed state, thereby limiting current drain arising from the external button being stuck in the pressed state.
