METHOD FOR REDUCING BATTERY CONSUMPTION ON BASIS OF USER'S USAGE PATTERN AND APPARATUS THEREFOR

摘要

Disclosed is a device according to an embodiment, comprising: a user input unit which receives a user input from a user; an output unit which outputs information on the basis of the user input; and a control unit which, as no user input is received, determines whether an out-of-focus state where a user does not use the device has begun, determines a period of time, for which the out-of-focus state will last, on the basis of information on the probability of being in the out-of-focus state according to a context of the device, when it is determined that the out-of-focus state has begun, and stops the operation of an application that is being executed on the device, when the determined period of time for which the out-of-focus state will last is equal to or longer than a reference time.
