A wearable device (100) and a power supply control method. The wearable device (100) comprises: a power source (110), an extended secure element (eSE) chip (120), a trigger circuit (140) and a power supply control unit (150), wherein the power supply control unit (150) is respectively connected to the power source (110), the trigger circuit (140) and the eSE chip (120); the trigger circuit (140) is used to generate a trigger signal and send the trigger signal to the power supply control unit (150); and the power supply control unit (150) is used to enable the power source (110) to supply power to the eSE chip (120) when a power supply control signal sent by the trigger circuit (140) is received, and enables the power source (110) to stop supplying power to the eSE chip (120) when a power supply cut-off control signal sent by the trigger circuit (140) is received. By means of the present invention, it is very convenient to control whether a power source (110) in a wearable device (100) needs to supply power to an eSE chip (120), so that useless power consumption of the wearable device (100) can be reduced to a great extent, and a standby time of the wearable device (100) can be further prolonged. |
