The invention discloses a power-saving terminal, which comprises a radio frequency module, a physical layer base band processing unit and a high-layer protocol processing unit, wherein the high layer protocol processing unit is provided with a timer used for controlling the time of the power saving terminal to read information. A power saving method of the terminal comprises the following steps: setting a time length of the timer as T, wherein the minimum Tmin of the time length T is a value greater than an information receiving period; receiving information; judging whether all information is read in the time length T of the timer or not; shortening the time length T of the timer; measuring whether a cell reselection standard is satisfied or not; prolonging the time length T of the timer; and performing cell reselection. The power-saving terminal and the method thereof have the advantages of shortening the time for unnecessary information reception and benefiting the cell selection or entering an idle state so as to achieve the effect of saving power.
