PURPOSE: A method for changing a battery during speech in a wireless terminal, having a small auxiliary battery is provided to change the battery without cutting off a speech path during speech. And the method enables the speech path to be maintained using minimum power in a busy state. CONSTITUTION: A controller(100) checks whether a present terminal is in a busy state. If the terminal is in a busy state, a power selector(151) checks whether the capacity of a main battery(161) is under a predetermined value. If so, the controller(100) outputs an alarm sound and a character message through a display unit(140) or a speaker. The controller(100) checks whether a key inputted from a key input unit(130) requests the performance of a battery change mode. If not, general operations are performed. If the key requests the performance of a battery change mode, the controller(100) changes a power source from the main battery(161) to an auxiliary battery(160), to perform an ultra power save mode. If a key for restoring to a normal mode is inputted from the key input unit(130) by a user, the controller(100) changes a power source to the main battery(161) to perform to a normal mode. |
