Abstract

The invention provides a wireless charging control method and a mobile terminal. The method includes the steps of lowering the current upper limit value of a second current limiting module when the mobile terminal is wirelessly charged and it is detected that the mobile terminal is in a constant-voltage charged stage, and lowering the current upper limit value of a first current limiting module according to the current upper limit value of the second current limiting module. By means of the wireless charging control method, the influences of the random variation of the system power consumptionon the voltage of the input end of a charging chip of the mobile terminal can be reduced, and the stability of the mobile terminal in the wireless charging process is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless charging control method and a mobile terminal. Background technique [0002] With the development of the wireless charging technology, the application of the wireless charging function in terminal devices (eg, mobile terminals) is becoming more and more popular. In practical applications, taking a mobile terminal as an example, the user may use the mobile terminal during wireless charging, for example, use the mobile terminal to watch videos, browse news, shop, chat online, etc. The state of the terminal is uncertain, and the power consumption state of the mobile terminal system is random, that is, the power consumption state of the mobile terminal system may increase or decrease randomly. [0003] At present, the energy required by the system power consumption of the mobile terminal is mainly obtained from two ways, one is obtained from the battery of ...
