[0010] figure 1 It is a flowchart of a power management method for a portable device in the present invention, which includes the following steps:

[0011] Step 110: Execute an application.

[0012] Step 120: Determine whether it is necessary to adjust the power supplied to a specific hardware module in a portable device when executing the application: if yes, perform step 130; if not, perform step 150.

[0013] Step 130: Determine a historical usage status of the specific hardware module when the application was previously executed.

[0014] Step 140 : Adjust the power supplied to the specific hardware module according to the historical usage conditions.

[0015] Step 150: Determine whether to continue to execute the application program: if yes, execute step 110; if not, execute step 160.

[0016] Step 160: Turn off the power supplied to the specific hardware module.

[0017] The present invention can be used in portable devices such as smartphones, notebook computers, an...

Abstract

The invention discloses a method for managing power of a portable device. The method for managing the power comprises the following steps of: judging a historical use condition when each hardware module in the portable device previously executes an application program; automatically regulating the power which is supplied to the corresponding hardware module according to the historical use condition when the application program is executed; and completely cutting off the power which is supplied to the hardware module with a low utilization rate when the application program does not need to be used; and reducing the power which is supplied to the hardware module with a high utilization rate. According to each hardware module in the portable device, by the method, the historical use condition can be judged when the application program is previously executed, the power which is supplied to the corresponding hardware module can be automatically regulated according to the historical use condition when the application program is executed, the power which is supplied to the hardware module with the low utilization rate is totally cut off when the application program does not need to be used; and the power which is supplied to the hardware module with the high utilization rate is reduced; and therefore, the method has the functions of saving power and ensuring system effectiveness.

Description

technical field [0001] The invention relates to a power management method of a portable device, in particular to a power management method of a portable device capable of both power saving and system performance. Background technique [0002] With the development of technology, the functions of portable devices such as smart phones, notebook computers, and PDAs are becoming more and more diverse. The portable device can execute different application programs through its built-in hardware modules, thereby providing functions such as calling, surfing the Internet, taking pictures, taking photos, playing video and audio, or global positioning. [0003] The biggest advantage of portable devices is that they are easy to carry, but their power supply is limited. For all hardware modules that may be used, the prior art will switch unused hardware modules to a power saving mode when the application program starts to execute, without dynamically performing power management according...
