Abstract: A device control system is disclosed. The system includes a first mobile terminal and a second mobile terminal. After enabling a wireless hotspot function, the first mobile terminal establishes a wireless fidelity (Wi-Fi) connection to the second mobile terminal, and transmits data to the second mobile terminal in a MIMO Wi-Fi antenna working mode. The first mobile terminal may monitor a remaining battery level and/or a device temperature of the mobile terminal. When the remaining battery level is less than a first battery level threshold and/or the device temperature is greater than a first temperature threshold, the first mobile terminal switches the Wi-Fi antenna working mode as SISO, limits a maximum forwarding rate of a TCP packet or a UDP packet to a first rate, and/or no longer responds to a probe request. In this way, power consumption of the first mobile terminal is reduced.
