Problems solved by technology

[0003] Among them, the debugging of the RF current can be mainly carried out in the following ways: The first method is the hardware debugging of the RF matching, which balances the linearity index and current parameters of the RF device, but the parameters of the RF matching device of the mobile terminal are already fixed before leaving the factory. Subsequent users cannot change the debugging by themselves; the second way is to adjust the static operating point (ICQ) of the RF power amplifier (PA). Under different static operating points, the adjacent channel leakage ratio (ACLR) and current have different performances, but This method will permanently affect the RF index performance

Abstract

The invention discloses a method and apparatus for improving radio frequency power consumption of a mobile terminal. The method comprises the following steps: detecting whether a mobile terminal is switched from a normal use electricity consumption mode to a smart electricity saving mode, and if the mobile terminal is switched from a normal electricity consumption mode to a smart electricity saving mode, then lowering the APT voltage value of a radio frequency power amplifier, such that ICQ of the radio frequency power amplifier is deviated from a normal point and ACLR property is lowered and working current is reduced. According to the invention, the method is easy to operate, enables the mobile terminal to acquire longer time of duration, improves user experience, enables a user to switch the mobile terminal between the two working modes on the basis of actual needs, and when the mobile terminal is switched to normal use electricity consumption mode, can guarantee radio frequency indexing property of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and more specifically, to a method and device for improving radio frequency power consumption of mobile terminals. Background technique [0002] At present, the radio frequency current of mobile terminals such as mobile phones is the largest power consumption part except processors and display screens. In addition to reducing the frequency of the processor and reducing the brightness of the display screen to reduce the current, the use time of the mobile terminal can also be increased by reducing the radio frequency current. [0003] Among them, the debugging of the RF current can be mainly carried out in the following ways: The first method is the hardware debugging of the RF matching, which balances the linearity index and current parameters of the RF device, but the parameters of the RF matching device of the mobile terminal are already fixed before leaving the factory. Subse...
