Problems solved by technology

[0005] However, in the above-mentioned conventional portable devices, only the remaining battery capacity relative to the full charge is displayed, and no information on the deterioration of the secondary battery is displayed.
Therefore, the user of the portable device cannot grasp the reduction in the remaining battery capacity due to the deterioration of the secondary battery.
And, the secondary battery is preferably replaced according to the situation of deterioration, but in the existing portable equipment, because the information about the deterioration of the secondary battery is not displayed to the user, it is difficult for the user to replace the secondary battery at an appropriate time. replacement

Abstract

Provided is a mobile device driven by a secondary battery which can be charged and discharged. The mobile device detects a full charge of the secondary battery which is repeatedly charged and acquires and stores the capacity of the secondary battery upon the full charge. The mobile device causes a display device to display a change of the capacity upon the full charge of the secondary battery in time series so that a user can recognize the degradation state of the secondary battery.

Description

technical field [0001] The present invention relates to a portable device driven by a rechargeable secondary battery to execute a plurality of applications, a battery pack mounted on the portable device, a display control method, and a display control program. Background technique [0002] Recently, along with miniaturization of electronic devices, portable devices driven by secondary batteries such as lithium ion batteries are spreading. In such a portable device, in order to prevent the portable device from becoming unusable due to a dead battery, the remaining battery level is usually displayed on a display or the like. Based on this display, the user of the portable device can use the portable device while being aware of the remaining battery level, and can charge the secondary battery at an appropriate time. [0003] For example, Japanese Patent Laid-Open No. 2007-309943 describes a method for measuring the remaining battery capacity of a secondary battery cell and a s...
