Abstract

A power control method of an electronic device is provided. The electronic device transmits power change information containing a power control value of an application to another electronic device, and receives and stores power control information about the application transmitted from the another electronic device. If a power level of the electronic device is lower than a predetermined power change level when the application is executed, the electronic device executes the application with power control data of the application in the power control information stored in the electronic device.

First claim

What is claimed is:

1. A power control method of an electronic device, comprising:
transmitting power change information of an application to another electronic device;
receiving and storing power control information of the application transmitted from the another electronic device; and
if a power level of the electronic device is lower than a predetermined power change level when the application is executed, executing the application based on the power control information stored in the electronic device,
wherein the power change information comprises a power control value which controls a frame rate of a screen of the application set by a user of the electronic device, and
wherein the power control information is determined based on a plurality of power control values transmitted from a plurality of apparatuses, in which an application installed is a same kind as the application.

2. The power control method of claim 1 , wherein the another electronic device is a server.

3. The power control method of claim 2 , wherein the power change information is transmitted to the server when the power control value of the application is changed.

4. The power control method of claim 1 , wherein the power control value is data for controlling an operating clock of a graphic processing unit or an operating clock of a control unit.

5. The power control method of claim 1 , wherein the predetermined power change level is a predetermined global power level, and
wherein executing the application includes:
comparing the power level of the electronic device with the predetermined global power level when the application is executed; and
executing the application based on the power control information of the application when the power level of the electronic device is lower than the predetermined global power level.

6. The power control method of claim 5 , wherein the predetermined power change level further includes a local power level set by a user, and
wherein executing the application further includes:
analyzing an execution mode when the application is executed;
comparing the power level of the electronic device with the predetermined global power level if the execution mode is an automatic mode, or comparing the power level of the electronic device with the local power level if the execution mode is a manual mode; and
executing the application based on the power control information of the application when the power level of the electronic device is lower than the predetermined global power level in the automatic mode or lower than the local power level in the manual mode.

7. The power control method of claim 1 , wherein executing the application includes executing the application with normal power data when the power level of the electronic device is a normal power level, and
wherein the normal power data controls the screen display of the application with a power level not lower than the power control information does.

8. The power control method of claim 7 , wherein the predetermined power change level is a predetermined global power level or a local power level set by a user, and
wherein executing the application includes:
analyzing an execution mode when the application is executed;
comparing the power level of the electronic device with the global power level if the execution mode is an automatic mode, and then executing the application with the normal power data of the application when the power level of the electronic device is not lower than the predetermined global power level;
comparing the power level of the electronic device with the local power level if the execution mode is a manual mode, and then executing the application with the normal power data of the application when the power level electronic device is not lower than the local power level; and
executing the application with the normal power data when the device power level is the normal power level.

9. The power control method of claim 1 , wherein transmitting the power change information includes:
if the power control value of the application is changed, creating the power change information containing a device type, an application name, a current device power level, and the power control value; and
transmitting the power change information to the server.

10. The power control method of claim 1 , wherein receiving and storing the power control information includes:
checking a device type of the power control information about the application; and
storing the power control information having a same device type as that of the electronic device,
wherein the power control information is obtained by averaging power control values of the application received from the plurality of apparatuses.

11. A method for processing power control information for power control of a plurality of first electronic devices at a second electronic device, the method comprising:
collecting power change information of an application transmitted from the plurality of first electronic devices in which an application installed is a same kind as the application;
generating a power control information of the application based on the plurality of the power control values transmitted from the plurality of first electronic devices; and
transmitting the power control information to the plurality of first electronic devices, wherein the power change information comprises a power control value which controls a frame rate of a screen of the application set by a user of the plurality of first electronic devices.

12. The method of claim 11 , wherein the first electronic device is a terminal, and the second electronic device is a server.

13. The method of claim 11 , wherein the power control information is an average value of the plurality of the power control values.

14. The method of claim 11 , wherein the power change information about the applications further contains device types,
wherein creating the power control information comprises creating the power control information for each of the device types, and
wherein transmitting the power control information includes transmitting the power control information corresponding to a device type of the first electronic device.

15. The method of claim 14 , wherein the device type of the first electronic device is determined according to a display size of the first electronic device and a quantity of power consumption required for an application display.

16. The method of claim 15 , wherein the power control information is transmitted in response to a request of the first electronic device, and
wherein the power control information corresponds to the device type of the first electronic device.

17. An electronic device comprising:
a communication interface;
a memory;
a display; and
a processor configured to:
control the communication interface to transmit power change information of an application to another electronic device, and to receive power control information of the application from the another electronic device,
control the memory to store the power control information of the application, and
execute, if a power level of the electronic device is lower than a predetermined power change level, the application based on the power control information,
wherein the power change information comprises a power control value which controls a frame rate of a screen of the application set by a user of the electronic device, and
wherein the power control information is determined based on a plurality of power control values transmitted from a plurality of apparatuses, i
