The battery life of a mobile communication terminal which performs activities at particular time intervals, or slots, is extended by controlling a slot cycle according to a remaining capacity of the battery. The terminal has a slot cycle index table for storing a plurality of reference levels and their corresponding slot cycle indexes. As a slot cycle change mode is set, the terminal detects the battery level in a prescribed level check cycle and compares the detected battery level with the reference levels in sequence. If the detected battery level is higher than a selected one of the reference levels, the terminal sets the slot index to a value corresponding to the selected reference level. Further, the terminal sets the slot cycle index corresponding to a longest slot cycle, when the detected battery level falls outside of a reference level range. |
