Abstract: An electronic device and method are disclosed. The electronic device includes a first and second housing movable relative to each other. The second housing supports a flexible display which may be at least partially exposed to an exterior, and at least partially stowed within the first housing based on the movement of the housings. A processor implements the method including detecting movement of the housings such that a visible display area of the display is changed, detecting whether the resizing meets a predetermined condition, and if resizing does not meet the predetermined condition, executing image processing on a portion of the resized visible display area.

Abstract: An electronic device includes a circuit board; a battery; and a charging circuitry for charging the battery. The electronic device also includes a first sensor positioned in a first area of the battery or in an area in proximity of the first area in the circuit board for measuring a first temperature corresponding to the first area and a second sensor positioned in a second area of the battery or in an area in proximity of the second area in the circuit board for measuring a second temperature corresponding to the second area. The electronic device also includes a processor, wherein the processor is configured to acquire the first temperature via the first sensor and the second temperature via the second sensor. The processor is also configured to charge the battery with a specified current when a difference between the first and the second temperature satisfies a designated condition.
