A battery-driven electronic device, e.g., a radio communication terminal, which is operable in different modes with related power consumption, includes a data presentation function and a power consumption detecting function to establish current power consumption based on established current power consumption. By detecting and presenting data pertaining to the current power consumption, rather than a predetermined expected way of use, such as talk mode or standby mode, better control may be given to a user of the device so that it may be operated in such a manner so as to extend the battery life.
