The processor is a control center of the mobile phone, is connected with each part of the whole mobile phone by various interfaces and lines, and executes various functions and processes data of the mobile phone by running or executing software programs and/or modules stored in the memory and calling the data stored in the memory, thereby carrying out the integral monitoring on the mobile phone. Alternatively, the processor may include one or more processing units; preferably, the processor may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.

It will be appreciated that the modem processor described above may not be integrated into the processor.

Also, the processor may perform the same or similar functions as the processing unit as the implementation elements of the processing unit.

The handset also includes a power source (such as a battery) to power the various components.

Optionally, the power supply may be logically connected to the processor through a power management system, so as to implement functions of managing charging, discharging, power consumption management, and the like through the power management system. Although not shown, the mobile phone may further include a bluetooth module, etc., which will not be described herein.

It should be noted that the mobile phone is only an example of the electronic device 100, and the present invention is not limited thereto, and the present invention can be applied to the electronic device 100 such as a mobile phone and a tablet computer, and the present invention is not limited thereto.
