Abstract: There is a demand for an information processing device capable of maintaining, as long as possible, a state in which a decrease an the processing speed of a CPU due to heat generation hardly occurs. Therefore, proposed is an information processing device including a secondary battery, and the information processing device includes a measurement unit that measures a remaining amount of the secondary battery, a determination unit that determines whether or not the remaining amount is equal to or more than a first threshold and determines whether or not a specific application is in a foreground state, and a charge control unit that stops charging the secondary battery by using an external power supply in a case where the remaining amount is equal to or more than the first threshold and the specific application is in the foreground state.

Abstract: A program causes an information processing apparatus to activate a second application that provides an extended function to a first application, superimpose and display a menu of the second application on the first application in response to a predetermined operation at a predetermined position on a screen where the first application is displayed and the second application is not displayed, and execute processing corresponding to the extended function selected from the menu.

Abstract: To provide an extension function that permits more intuitive operations without interfering with the behavior of an external application. There is provided an information processing apparatus that includes a controller configured to control functional extension of an external application. The controller causes an extended menu icon whose display position is adjustable to be superimposed and displayed on a display window of the external application, and controls a display position of an extended menu according to the display position of the extended menu icon. The controller causes an extension function icon to be superimposed and displayed on the display window with a display position of the extension function icon being adjustable, the extension function icon being associated with an extension function selected on the extended menu, and controls a display position of a sub-icon accompanying the extension function icon, according to the display position of the extension function icon.
