A mobile phone power saving setting, realizing, through a clock circuit and an excitation switching circuit integrated on a main circuit board, an intermittent on state of a main circuit of the whole mobile phone when there is no electrical message. The specific principle is that the main circuit board of the whole mobile phone is in an intermittent on state through the clock circuit and the excitation switching circuit. That is, the whole mobile phone is automatically powered on once every few seconds, and when there is no electrical signal, the mobile phone is in a state of flashing once every few seconds; when there is an electrical signal, the signal meets the flashing mobile phone signal, and the whole mobile phone is in a continuous power-on state through the excitation switching circuit, and after the electrical communication is completed, the mobile phone is in an intermittent excited state again. Or, when there is no electrical signal, the clock circuit and the excitation switching circuit are in an on state (at this time, the clock circuit may be omitted) or an intermittent on state, and the circuit of the whole mobile phone is in an off state; when there is an electrical signal, the whole mobile phone is on through the excitation switching circuit or intermittent flashing of the clock circuit and the excitation switching circuit meets the electrical signal, and the whole mobile phone is in an on state through the excitation switching circuit, after the electrical communication is completed, the whole mobile phone restores the off state again, and the clock circuit and the excitation switching circuit are in the intermittent flashing state again, and in the case that the clock circuit is not disposed, the whole mobile phone is in a partial on state again, that is, the excitation switching circuit is in the on state. The clock circuit and the excitation switching circuit may be disposed separately and connected to the circuit board of the whole mobile phone or may be integrated on the circuit board of the whole mobile phone. The clock circuit and the excitation switching circuit may be powered separately by a small lithium battery or may be powered by a battery of the mobile phone. The present invention has advantages of long standby time on a single charge, reduced charges, extended battery life and convenient use, and is worth popularization. |
