The mobile terminal further include: the first field effect transistor and the second field effect transistor are series at the connection line On, wherein one end of first field effect transistor is connect with the charging interface, and the other end and second field-effect are brilliant The connection of body pipe, control terminal are connect with second control unit；One end of second field effect transistor with described first Effect transistor connection, the other end are connect with the battery and the main system, and control terminal is connect with second control unit；

Second control unit is also used to for current charge mode to be determined as the fast charge mode or the common charging After mode, controls first field effect transistor and second field effect transistor is in the conductive state, to the electricity Pond quick charge or common charging, and power to the main system；Current charge mode is determined as the slow charging mode Afterwards, one controlled in first field effect transistor and second field effect transistor is in the conductive state, another In linear working state, to charge at a slow speed to the battery, and power to the main system；Export the stopping charging signals Afterwards, it controls first field effect transistor and second field effect transistor is in an off state, to stop to the electricity Pond charging, and stop powering to the main system.

16. mobile terminal as claimed in claim 15, which is characterized in that

The connection line includes: controllable switch, and one end of the controllable switch is connect with the battery, the other end and the master System is connected with charging interface, and control terminal is connect with second control unit；

Second control unit is also used to for current charge mode to be determined as the fast charge mode, the common charging After mode or the slow charging mode, it is in the conductive state to control the controllable switch, to charge to the battery, and detects The electricity of the battery, when the electricity is full power consumption, it is in an off state to control the controllable switch, to stop to institute Battery charging is stated, continues to power to the main system；After exporting the stopping charging signals, control the controllable switch be in lead Logical state, so that the battery powers to the main system.
