The embodiments of the present disclosure provide an application function control method and a related product. The method is applied to a mobile terminal including a processor and an Artificial Intelligence (AI) module, and includes that: the mobile terminal controls the processor to, in response to detecting a starting instruction for a first application, send a first instruction containing an application identifier of the first application to the AI module; the mobile terminal controls the AI module to receive the first instruction and query whether a preset disabled function set includes a function of the first application or not; the mobile terminal controls the AI module to, in response to finding out that the disabled function set includes at least one first function of the first application, send a second instruction containing a function identifier of the at least one first function to the processor; and the mobile terminal controls the processor to receive the second instruction and run a plurality of functions in multiple functions of the first application other than the at least one first function. According to the embodiments of the present disclosure, "application thinning" is implemented, and improvement in utilization efficiency of processing resources of the mobile terminal and reduction in power consumption are facilitated.
