Step 201. Detect the status of the currently connected Wi-Fi WiFi.

Step 202, when it is detected that the received signal strength RSSI of the WiFi gradually decreases within the first set time, and the current terminal is disconnected from the access point corresponding to the WiFi, automatically shut down the WiFi function of the current terminal.

Wherein, the detecting that the received signal strength RSSI of the WiFi gradually decreases within the first set time is specifically detecting that the received signal strength RSSI of the WiFi gradually decreases within the set time. Wherein, the trend of the RSSI gradually decreasing within the set time is specifically: within the first set time, the RSSI value of the WiFi signal detected regularly, most or all of the RSSI values at the next moment are less than The RSSI value at the last moment. Wherein, the start time of the first set time is the time when the value of RSSI is detected to be decreasing. The start time of the first set time and the end time of the first set time may be 5 minutes or 10 minutes after the start time, which may be specifically determined according to the user's moving speed and the strength of the WiFi signal.
