Abstract: The present disclosure relates to user-mode interrupt request processing methods and apparatuses. In one example method, a central processing unit (CPU) in a kernel mode runs a second interrupt exception handler that does not include a kernel address to determine a user-mode interrupt handler corresponding to a user-mode interrupt request, switches to a user mode by using a first privilege level without context recovery, further runs the user-mode interrupt handler in the user mode, and then switches to the kernel mode by using a second privilege level without context storage.

Abstract: A power consumption exception prompt method includes: receiving, by a server, report information sent by a terminal, where the report information includes running information of a first application program on the terminal and power consumption of the first application program on the terminal, and the first application program is any application program on the terminal; determining, by the server based on the report information, whether the power consumption of the first application program on the terminal is abnormal; and when determining that the power consumption of the first application program on the terminal is abnormal, sending, by the server, prompt information to the terminal, where the prompt information is used to indicate that the power consumption of the first application program on the terminal is abnormal.
