Claim 12:
13. The electronic device of claim 12, further comprising:
a charging power unit comprising a second diode, a capacitor, and a third diode,
wherein an anode of the second diode is electrically connected with the driving power supply unit,
wherein a cathode of the second diode is electrically connected with a first terminal of the capacitor and is electrically connected with an anode of the third diode,
wherein a second terminal of the capacitor is electrically connected with a ground,
wherein a cathode of the third diode is electrically connected with each of the control unit and the temperature sensor,
wherein the capacitor is charged based on a voltage applied through the second diode while the user device is in the first designated state,
wherein the temperature sensor maintains an activate state based on a voltage of the charged capacitor, while the user device is in the second designated state, and
wherein the control unit is configured to:
switch a state of the control unit to a sleep state, in response to switching from the first designated state to the second designated state;
switch the sleep state to a wake-up state based on designated cycle while the user device is in the second designated state; and
identify, while the control unit is in the wake-up state, a level of the voltage of the charged capacitor reaches below a designated level.
