Abstract: An information processing terminal improves user convenience by more accurately displaying a remaining charge of a battery installed. The battery is any one of a plurality of batteries differing in chargeable capacity. The mobile phone has a battery-type judging unit that reads a signal output from a battery-type output unit of the battery and judges which of two types of batteries differing in chargeable capacity is installed. A voltage measuring unit measures the output voltage of a cell unit. A threshold setting unit acquires thresholds corresponding to the judged battery type and a judging unit judges, using the thresholds, a battery icon to be displayed. A battery icon for a large-capacity battery includes four battery bars at maximum. A battery icon for a normal-capacity battery includes three battery bars at maximum. A display, generating unit causes a display unit to display the battery icon according to the judgment.
