The electronic device 1 can be a Personal Digital Assistant (PDA), a mobile phone, or the like. The electronic device 1 is configured to control the power-on condition of the GPS system 2, and when the displacement of the electronic device 1 does not change, the GPS system 2 enters a power-saving mode, thereby saving the GPS. The power consumption of the system 2 ultimately saves power consumption of the electronic device 1 to extend standby time.

The electronic device 1 further includes a processor 4 and a memory 5. The processor 4 is configured to execute software installed in the electronic device 1, such as an operating system and other applications.

The memory 5 is used for storing various types of materials, including data set in the electronic device 1, data acquired by the GPS system 2 and the acceleration sensor 3, and the like. The memory 5 can be built in the electronic device 1 and can be externally connected to the electronic device 1.

The electronic device 1 mainly includes four functional modules, namely: a setting module 10, an acquiring module 12, a determining module 14, and a control module 16.

The setting module 10 is configured to set a time interval for collecting motion parameters of the electronic device 1, for example, the time interval may be set to 0.01 seconds.

The setting module 10 is further configured to set a shortcut key for starting/closing the GPS system 2. In the preferred embodiment, in order to save power consumption of the GPS system 2, when the GPS system 2 is activated, the acceleration sensor 3 is also activated accordingly.

The acquisition module 12 is configured to collect the motion parameters generated by the acceleration sensor 3 according to the set time interval. The motion parameters generated by the acceleration sensor 3 include parameters such as a motion direction and a motion acceleration magnitude.

The acquisition module 12 is further configured to store the collected motion parameters generated by the acceleration sensor 3 into the memory 5. The memory 5 may be preset with an area for storing data acquired by the acceleration sensor 3, and the data in the area may be periodically cleared to ensure sufficient space in the area.

The determining module 14 is configured to determine whether the electronic device 1 is displaced according to the set time interval and the collected motion parameter.
