LTE has been touted as the forth generation mobile communication technology offering high data rate and low delay.However, with telecom terminal product to boost performance, the processing demands on terminal is enormous, and at the same time energy consumption is heavy. This paper from the power consumption of the mobile terminal performance, Analyzes the main factors of influence terminal power level in LTE, The discussion focused on the cell search process how to apply the DRX to save power energy, puts forward a new feasible solution. It can help to save unnecessary power consumption and plays an important role in extending the standby time of UE.
