detecting whether the power saving mode is in an enabled state, when the screen of the terminal is switched from the screen-on state to the screen-off state; or

detecting whether the power saving mode is in an enabled state and whether a current time period is within a rest time period of a user, when the screen of the terminal is switched from the screen-on state to the screen-off state.

9. The method according to claim 1 , wherein after performing a power saving operation, the method further comprises:

canceling performing the power saving operation, when the screen of the terminal is switched from the screen-off state to the screen-on state.

10. A terminal, comprising:

a processor; and

a memory and a screen that are electrically connected to the processor, wherein the memory stores one or more instructions which, when executed by the processor, cause the terminal to:

detect whether an enabling condition of a power saving mode is satisfied, when the screen is switched from a screen-on state to a screen-off state, and

perform a power saving operation, when the enabling condition of the power saving mode is satisfied, to reduce power consumption that occurs when an application program in the terminal runs in a background, wherein performing a power saving operation comprises stopping a first-type application program; and

after stopping the first-type application program, prohibit automatic start of the stopped first-type application program, wherein prohibiting automatic start of the stopped first-type application program comprises intercepting a broadcast message sent to the stopped first-type application program to prohibit the broadcast message from triggering the first-type application program to start.

11. The terminal according to claim 10 , wherein to perform the power saving operation, the one or more instructions, when executed by the processor, further cause the terminal to:

disconnect a network connection of a second-type application program;

pause a timer of a third-type application program; or

switch from an initial network switching mode to a target network switching mode, wherein a network mode used in the target network switching mode does not comprise a network mode in which signal quality is lower than expected quality.

12. The terminal according to claim 10 , wherein the one or more instructions, when executed by the processor, further cause the terminal to:

after the screen-off state lasts for a first time period, search for the first-type application program, wherein the first-type application program is an application program that is in a running state and that has not performed a network-connecting operation within the first time period; and

stop the first-type application program.

13. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to:

detect whether an enabling condition of a power saving mode is satisfied, when a screen of a terminal is switched from a screen-on state to a screen-off state; and

perform a power saving operation, when the enabling condition of the power saving mode is satisfied, to reduce power consumption that occurs when an application program in the terminal runs in a background, wherein performing a power saving operation comprises stopping a first-type application program; and

after stopping the first-type application program, prohibit automatic start of the stopped first-type application program, wherein prohibiting automatic start of the stopped first-type application program comprises intercepting a broadcast message sent to the stopped first-type application program to prohibit the broadcast message from triggering the first-type application program to start.

14. The non-transitory computer-readable storage medium according to claim 13 , wherein performing a power saving operation further comprises performing at least one of the following operations:
