Portable electronic device and wireless communication device

A wireless communication device comprising:

• a battery;
• a current measurement unit which is connected to the battery and measures a current, the current being output from the battery and flowing through an output current monitoring resistor;
• a communication unit which performs wireless communication;
• a control unit which can execute a plurality of application programs including an application program for controlling communication by the communication unit;
• and a storage unit which stores a current threshold value set for each of the plurality of application programs executable by the control unit, wherein the control unit monitors a current value measured by the current measurement unit and a type of application program being executed, and executes a reset process or a power-off process when the current value measured by the current measurement unit exceeds a current threshold value corresponding to the type of application program currently being executed, wherein each current threshold value corresponds to a different application program and each current threshold value is different from the other current threshold values, and wherein the control unit forcibly executes the power-off process in response to the number of times that the current value measured by the current measurement unit exceeds the overcurrent threshold value reaching a predetermined number of times, regardless of the application program being executed.
