The invention discloses a power-saving wireless mouse, which is characterized by the following: when the output mode sends order, the triggering power mode charges battery and the output end triggers power circuit conducting of central disposal element, transmission mode and transmission antenna with mouse working normally. Otherwise, triggering power circuit discharges insides to maintain power circuit conducting with keeping mouse sensitivity. When the power circuit stops, the power mode finishes discharging insides without any energy consumption of the mouse. |
