To provide a communication apparatus allowing a user to easily recognize a communication service time using one radio communication scheme and a communicable service time using other radio communication scheme when communication is established using one of the radio communication schemes of the communication apparatus.
A communication apparatus 100 comprises: a battery unit 103; a first radio communication unit 101 which is supplied with power from the battery unit and performs communication using a first radio communication scheme; a second radio communication unit 102 for performing a communication using a second radio communication scheme different from the first radio communication scheme; a measurement means 104 for measuring remaining battery capacity of the battery unit; a communication time calculating means 107 for calculating the remaining time for the communication using the first radio communication unit, and the remaining time for the communication using the second radio communication unit, on the basis of the remaining battery capacity; and a display means 110 for displaying the remaining time for the communication using one radio communication unit, and the remaining time for the communication using the other radio communication unit, in different display modes.
