A portable communication device, according to various embodiments of the present disclosure, may include: a battery pack; a power dissipation element disposed outside the battery pack; a detecting circuit configured to detect the state of the battery pack; and at least one of first switches that are connected to the battery pack and the detecting circuit, wherein the detecting circuit is configured to control at least one of the first switches to: electrically disconnect the power dissipation element from the battery pack when the state of the battery pack does not satisfy a specified condition; and electrically connect the power dissipation element to the battery pack when the state of the battery pack satisfies the specified condition.

Circuit for controlling power output from battery pack and battery pack

An apparatus and method operate a portable terminal according to touch and movement. When a touch is sensed, an angle of the portable terminal is determined. When the determined angle belongs to a grip zone, the portable terminal is transitioned to a wake up state.

Apparatus and method for operation according to movement in portable terminal

A method and apparatus perform pressure detection in a mobile terminal. method determines a squeezing pressure of the mobile terminal. The method determines whether a user squeezes the mobile terminal using the squeezing pressure determined and a value of a proximity sensor. The method transitions the mobile terminal to a wakeup state in response to determining that the user squeezed the mobile terminal.

Apparatus and method for operation according to squeezing in portable terminal

A charging apparatus and method for charging a battery of a mobile terminal using a thin film printed solar cell. The apparatus has an outer case including electrochromic elements and a thin film printed solar cell. A control unit controls charging of the battery so that a color of the electrochromic elements is changed into a transparent color and sunlight is transmitted to the thin film printed solar cell disposed under the electrochromic elements. Also, the control unit controls charging of the battery such that a color of the outer case is automatically changed into a transparent color so that sunlight is transmitted to the thin film printed solar cell. Also, the color of the electrochromic elements can be changed according to the user's request so that the color of the outer case is changed into a desired color.
