A wireless device and a power-saving device thereof are provided. The power-saving device includes a bracket, a rocker arm and a struck element. The bracket is electrically connected to a circuit board of the wireless device. The rocker arm is movably disposed on the bracket. The struck element is disposed around the rocker arm and electrically connected to the circuit board. When the wireless device is moved and makes the rocker arm move waveringly and touch the struck element, the circuit board is therefore conducted, such that the wireless device switches from a sleep mode to an operation mode.
