Method and device for detecting CPU occupancy rate abnormalities of APPs and mobile terminal

The invention provides a method and device for detecting CPU occupancy rate abnormalities of APPs and a mobile terminal. The method includes the steps that parameter information of the currently-operating APPs is acquired, and a query request with the parameter information is sent to a server so that the server can acquire a query result according to the query request; the query result returned by the server is received, and whether the CPU occupancy rates of the corresponding APPs are abnormal or not is determined according to the query result; when the CPU occupancy rates of the corresponding APPs are abnormal, prompt information is displayed. According to the method and device for detecting the CPU occupancy rate abnormalities of the APPs and the mobile terminal, whether the CPU occupancy rate of each APP in the terminal is abnormal or not can be accurately determined, when the CPU occupancy rate is abnormal, a user can conduct related processing on the APPs with the CPU occupancy rate abnormalities according to the displayed prompt information, the influences of the APPs with the CPU occupancy rate abnormalities on a terminal system are reduced, and then the operating efficiency of the terminal system can be improved.
