停止させる。Reducing the transmit level of a mobile phone reduces the discharge current from the battery. As the telephone is operated, the battery voltage gradually decreases, and when this reaches, for example, the first stage setting value, the transmission level is lowered. This delays the time to reach the acceptable terminal voltage of the battery. moreover,
When the second stage set value is reached, the transmission level is further reduced, and when it continues to reach the final voltage of 1, the operation of the telephone is stopped.
