Method and apparatus for reducing power consumption based on use pattern of user
First Claim
1. A device comprising:
- a touch screen; and
at least one processor configured to at least;
when a user input is not received for a preset time period via the touch screen, turn off the touch screen and determine that an out-focus status in which the user does not use the device has started,based on both the out-focus status being started and a current context of the device, identify a probability of the out-focus status being maintained,based on the identified probability of the out-focus status being maintained, calculate an expected period in which the out-focus status is to be maintained from when the out-focus status has started, andbased on both the out-focus status being started and the expected period being equal to or greater than a reference time period, stop an operation of an application which is being executed in a background on the device.

Abstract
A device and method of managing power are provided. The device includes a user input unit configured to receive a user input from a user, an output unit configured to output information based on the user input, and a controller configured to, when the user input is not received, determine whether or not an out-focus status in which the user does not use the device has started, determine, when it is determined that the out-focus status has started, a period in which the out-focus status is to be maintained based on information about a probability of the out-focus status according to a context of the device, and stop, when the period in which the out-focus status is to be maintained is equal to or greater than a reference time period, an application executed in the device.
