ABSTRACT:
A mobile communication terminal and a method for warning a user of a low-voltage state of the terminal. The method includes the steps of pre-storing a low-voltage alarm message in a memory, checking a voltage level of a battery in a call connection mode, and if the voltage level of the battery is lower than a predetermined voltage, reading the low-voltage alarm message from the memory and transmitting the read low-voltage alarm message to a called terminal communicating with the mobile communication terminal. A caller mobile communication terminal can thus inform a called mobile communication terminal that the breaking of a call connection state was caused by a low-voltage state of a battery of the caller terminal.
