The method for adjusting a shutdown threshold voltage includes: obtaining a current voltage of a battery of an electronic device; when the current voltage is greater than or equal to a lowest shutdown threshold of the electronic device and less than or equal to a general shutdown threshold of the electronic device, obtaining at least one piece of application information of at least one application program, where an application shutdown threshold of an application program corresponding to each piece of application information of the at least one piece of application information is greater than the lowest shutdown threshold and less than or equal to the current voltage; and setting a current shutdown threshold, which is corresponding to the current voltage, of the electronic device to a maximum application shutdown threshold of at least one application shutdown threshold corresponding to the at least one application program.
