The S310 operation is an operation for displaying an application screen.

The control unit 170 can execute the application according to the selection or automatic setting of the user and display the screen of the executed application (that is, the application screen) on the display unit 160. [

The S320 operation is an operation for detecting the state of the electronic device.

The control unit 170 detects the state of the electronic device 100 through at least one of the sensor unit 130, the communication unit 150, and the camera 140.

For example, the control unit 170 controls the remaining battery capacity, the load (or system load) of the control unit 170, the brightness state of the screen (or the display unit 160), the input frequency of the user, Can be detected.

The S330 operation is an operation for determining whether or not the change condition of the update period is satisfied.

The control unit 170 determines whether or not the state of the detected electronic device 100 satisfies the change condition of the update period.

For example, the control unit 170 may determine whether the battery remaining amount is less than or equal to a preset threshold value (e.g., 10% of the battery capacity), determine whether the system load is equal to or less than a preset threshold value (e.g., 10% It is determined whether the screen brightness is equal to or less than a set threshold value (for example, 10% of the maximum brightness) or whether the frequency of the user's input (touch, hovering, gesture, etc.) is equal to or less than a set threshold value , Or an input frequency (or communication data amount) of an external electronic device (e.g., a wearable device such as a smart glass or a smart watch) is equal to or less than a set threshold value. Alternatively, the control unit 170 can determine whether the strength of the user input, such as voice, is below a threshold value. Conversely, the condition for changing the update period may be an abnormality (or an excess) of the above-mentioned threshold value.

The controller 170 may perform the operation S350 if the condition for changing the update period is satisfied, and otherwise, perform the operation S340.

The S340 operation is an operation of maintaining the initial update period.

The control unit can maintain the initial update period at the time when the application is executed when the update period change condition is not satisfied.

The S350 operation is an operation of changing the update period.

For example, if the battery remaining amount is less than or equal to a set threshold value (e.g., 10% of the battery capacity), the control unit 170 may increase the screen update period to a set value (for example, from 2 minutes to 3 minutes) .

For example, if it is determined that the system load is less than or equal to a predetermined threshold (e.g., 10% of the system processing capacity), or if the screen brightness is less than or equal to a preset threshold value (e.g., 10% To a set value (e.g., increased from two minutes to three minutes).

For example, if the screen brightness is less than or equal to a predetermined threshold (e.g., 10% of the maximum brightness), the controller 170 may increase the screen update period to a set value (e.g., increased from two minutes to three minutes) .

For example, if the input frequency of the user is less than or equal to a predetermined threshold value (e.g., less than or equal to one third), the control unit 170 may increase the screen update period to a predetermined value (for example, two to three minutes .

For example, when the input frequency of an external electronic device (e.g., a wearable device such as a smart glass or a smart watch) is less than or equal to a preset threshold value (for example, once every 3 seconds), the control unit 170 sets the screen update period to a set value (For example, from 2 minutes to 3 minutes). On the other hand, if the remaining battery power / system load / screen brightness / user's input frequency / external electronic device input frequency is lower than the corresponding threshold value or the second threshold value (for example, 50% Or more (or more) than the update period.

The increase in the period that is changed according to the set threshold condition may be replaced with the decrease, and the decrease in the period that is changed according to the set threshold condition may be replaced with the increase.

The control unit 170 controls the A, B, and C application screens 410 and 420 (see FIG. 4) if the battery remaining amount / the system load / the screen brightness / the input frequency of the user / the input frequency of the external electronic device is above , And 430 may be reduced to 1 minute, 1 minute, and 4 minutes, respectively, in accordance with a separate application. The control unit 170 controls the power consumption of the external electronic device based on the battery remaining amount / the system load / the screen brightness / the input frequency of the user / the strength of the user input / the input frequency of the external electronic device / (Or more) or a state above or equal to the first threshold (or above) is maintained for a set amount of time, the update periods of the A, B, and C application screens 410, 420, And can be reduced to 20 seconds, 30 seconds, and 3 minutes, respectively.
