[0002] At present, wireless fidelity Wi-Fi hotspots can be seen everywhere, and Wi-Fi functions have become the standard configuration of mobile terminals such as smart phones and tablet computers. Mobile terminals can access the Internet anytime and anywhere after accessing these Wi-Fi hotspots. It also causes that in most cases, users generally keep the Wi-Fi function of the mobile terminal turned on for a long time, even if they are not currently connected to a Wi-Fi hotspot
[0003] However, when the Wi-Fi function of the mobile terminal is turned on, if it is not currently connected to a Wi-Fi hotspot, the mobile terminal will periodically wake up the system and use the Wi-Fi module to scan for Wi-Fi hotspots in the surrounding environment. This will obviously lead to greater power consumption, resulting in a significant reduction in the standby time of the mobile terminal, and at the same time, the scanning efficiency of Wi-Fi hotspots is low

The embodiment of the invention provides a wireless fidelity (Wi-Fi) hotspot scanning method and a terminal. The method comprises the following steps: determining M first channels from preset K wireless channels, wherein K is an integer being greater than 1, and M is an integer being greater than 0; setting the scanning duration of each of the M first channels as first duration, and setting the scanning duration of each of N second channels except the M first channels in the K wireless channels as second duration, wherein the first duration is greater than the second duration, and N=K-M; scanning Wi-Fi hotspots on the preset K wireless channels by a configured Wi-Fi module according to a preset channel scanning sequence and scanning duration; and outputting Wi-Fi hotspot scanning results on the preset K wireless channels. Through the embodiment of the invention, the power consumption of the terminal needed in a Wi-Fi hotspot scanning process in a standby state can be effectively lowered; the standby time of the terminal is prolonged; and the Wi-Fi hotspot scanning efficiency is increased.
