ELECTRONIC DEVICE AND PERFORMANCE OPTIMIZATION METHOD THEREOF

An electronic device and a performance optimization method thereof are provided. The electronic device includes a battery module, a processor and a controller. The battery module is configured to supply power to the electronic device. The processor has a power consumption limit. In a power connection state, the controller determines whether to disable a power consumption limit adjustment function of the processor according to a source power provided by a power adapter and a system performance use setting of the electronic device. When the power consumption limit adjustment function is disabled, the processor executes an application program to monitor a storage capacity of the battery module and adjusts the system performance usage setting according to the storage capacity.
