Abstract

The invention is suitable for the field of a mobile terminal, and provides a charging method and a mobile terminal. The method comprises: sending a fast charging command to a second controller when the connection between a charging adaptor and the mobile terminal is detected by a first controller; judging whether the charging adaptor has the ability to output the pressure specified by the fast charging command or not when the fast charging command is received by the second controller, and sending a fast charging response command to the first controller if the charging adaptor has the ability to output the pressure specified by the fast charging command; communicating one or more than one charging loops of which the batteries are charged by auxiliary charging circuits when the fast charging response command is received by the first controller; realizing the fast charging of the batteries by that the batteries are simultaneously charged by the one or more than one auxiliary charging circuits which are parallel.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a charging method and a mobile terminal. Background technique [0002] With the progress of the times, the Internet and mobile communication networks provide a large number of functional applications. Users can not only use mobile terminals for traditional applications, such as: use smart phones to answer or make calls; at the same time, users can also use mobile terminals for web browsing, picture transmission, games, etc. As the frequency of use of the mobile terminal increases, the mobile terminal needs to be charged frequently. [0003] In the existing mobile terminal, a charging chip is provided inside, and after the charging adapter is connected (for example, plugged in) to the mobile terminal, the battery of the mobile terminal is charged through the charging chip. However, charging the battery cells through a single charging chip has a slow charging rate and ...
