Abstract: An electronic apparatus including a battery; and a controller configured to acquire use information of the battery, variably set a threshold range between a first threshold and a second threshold based on the acquired use information, and charge the battery when a sensed temperature of the battery is greater than or equal to the first threshold and less than or equal to the second threshold.

Abstract: Provided is a mobile terminal (electronic device) which, in order to minimize aging of a battery included therein through repeated charging/discharging, comprises: the battery charged by a voltage applied thereto; a monitoring device for monitoring a charging condition of the battery, and a charging frequency of the battery; a battery charger for adjusting the voltage applied to the battery; and a controller for controlling the battery, the monitoring device, and the battery charger, wherein, when the battery is charged in a pre-configured charging condition, the controller controls the monitoring device to adjust the charging frequency in response to the pre-configured charging condition, and controls the battery charger to apply a voltage corresponding to the adjusted charging frequency to the battery.

Abstract: Disclosed is a wireless power receiving apparatus for wirelessly receiving power. The wireless power receiving apparatus includes a power receiving unit configured to wirelessly receive power, a charging unit configured to receive the power from the power receiving unit, and supply the power to a battery, and a control unit configured to determine an output voltage, which enables a charging efficiency of power, supplied to the battery, to be the maximum, based on an output capacity output from the power receiving unit, and control the power receiving unit for the battery to be charged with the output voltage.

Abstract: A mobile terminal having a face recognition function and a control method thereof are provided. A mobile terminal includes a display unit, a memory, a photographing unit and a controller. The memory stores first photographing distance information mapped to a plurality of coordinates in a previously obtained first face image, as reference information for releasing a lock mode in which a touch input applied to the display unit is restricted. The photographing unit obtains a second face image by photographing a subject, when a face recognition function is performed in the lock mode. The controller computes second photographing distance information mapped to the plurality of coordinates in the second face image, and releases the lock mode, based on a result obtained by comparing the first photographing distance information and the second photographing distance information.
