Fast charging method and a mobile terminal

The present invention discloses a kind of fast charging method and a mobile terminal, based on a dynamically adjustable output voltage of the power adapter proposed by the voltage of the battery cell is divided into a plurality of range segment, and then uses a segmented type constant current charging manner, the the mobile terminal internal battery cell voltage range segment which is located, in a dynamically adjust the value of the charging process by the power adapter volt charging voltage output, and directly using direct charge the battery charging voltage adapter output power, whereby achieve significantly improved charging current, which in turn accelerates the rate of battery charging, mobile terminal to shorten the time required for a single charge, reducing the need for frequent affected by the mobile terminal, for a long time to charge users for everyday use caused, to a large extent enhance the satisfaction of users.
