Smart power saving method for terminal, terminal, and device having memory function

A terminal, comprising a processor and a memory electrically connected to the processor, wherein a smart power saving method for a terminal is executed when the processor is in operation, the memory stores an execution result of the processor and a program data of the smart power saving method for the terminal, and the smart power saving method for the terminal comprises:

• acquiring an IP lease duration corresponding to an IP address of a Wi-Fi connection with the terminal;
• determining whether the IP lease duration is not larger than a preset threshold;
• determining whether the terminal meets a preset condition;
• removing a first lease process, when the terminal meets the preset condition, and the IP lease duration is not larger than the preset threshold.

A device with a memory function, wherein the memory device stores a program data, a smart power saving method for a terminal is performed when the program data is executed, the smart power saving method for the terminal comprises:

• acquiring an IP lease duration corresponding to an IP address of a Wi-Fi connection with the terminal;
• determining whether the IP lease duration is not larger than a preset threshold;
• determining whether the terminal meets a preset condition;
• removing the first lease process, when the terminal meets the preset condition, and the IP lease duration is not larger than the preset threshold.
