Title: CHARGING METHOD AND MOBILE TERMINAL
Abstract:
A charging method and a mobile terminal. The charging method comprises: using a universal serial bus (USB) data line to establish a connection relationship with a power supply terminal, and setting a connection mode corresponding to the connection relationship as a working mode (S101); receiving a voltage selection instruction, and according to the voltage selection instruction, adjusting a voltage selection level (S102); when the voltage selection level is switched from a first level to a second level, adjusting the connection mode form the working mode to a charging mode, and receiving a charging current, transmitted by the power supply terminal, in the charging mode (S103), wherein the second level is higher than the first level. The charging method can increase a charging current of using a USB data line to connect a power supply terminal so as to charge the mobile terminal, and improve the charging efficiency of the mobile terminal, thereby ensuring the normal usage of each application program in the mobile terminal.
