The invention discloses an ultra-low power consumption standby bluetooth device and an implementation method thereof. The bluetooth device comprises a main body and a switch device, a control circuit is arranged in the main body, the control circuit comprises a bluetooth module, a low level trigger ultra-low power consumption switch module and a high level trigger reset switch module, the low level trigger ultra-low power consumption switch module is connected with a deep sleep control pin of the bluetooth module, the high level trigger reset switch module is connected with an ON/OFF end of the bluetooth module, and a switching device controls the low level trigger ultra-low power consumption switch module and the high level trigger reset switch module to work. When a 50MAH battery is used on a bluetooth headset, standby current is 0.5muA, theory standby time can as long as 2500 hours which is amounted to 104 days, and when the ultra-low power consumption standby bluetooth device is used on the bluetooth headset, the standby time can increase from 4 days to 104 days, 100 days of standby time are increased, charging frequency is greatly reduced, and using convenience is increased.
