The embodiment of the invention discloses a charging method and device. The charging method comprises the steps of acquiring the port type of a charger, and judging whether the port type is a standard downstream port (SDP) type or a charging downstream port (CDP) type; if the port type is the SDP type or the CDP type, adopting a preset current threshold corresponding to the SDP type or the CDP type to perform charging; if the port type is not the SDP type or the CDP type, judging whether the port type is a dedicated charging port (DCP) type or not; if the port type is the DCP type, acquiring a charging protocol; when the charging protocol comprises a Qualcomm quick charge 2.0 (QC 2.0), adopting a charging scheme corresponding to the QC 2.0 to perform charging; when the charging protocol comprise a pump express plus 3.0 (PE+ 3.0), adopting a charging scheme corresponding to the PE+ 3.0 or a charging scheme corresponding to a pump express plug 2.0 (PE+ 2.0) to perform charging; when the charging protocol comprises the pump express plus 2.0 (PE+ 2.0), adopting the charging scheme corresponding to the PE+ 2.0 to perform charging. By adopting the charging method and device disclosed by the embodiment of the invention, charging is performed through detecting the port type of the charger and adopting a charging mode corresponding to the port type, and thus the service life of a mobile terminal is prolonged.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a charging method and device. Background technique [0002] With the development of mobile terminal technology, mobile terminals such as mobile phones and tablet computers have more and more functions, and have gradually become an indispensable part of people's work and life. [0003] However, as the functions of the mobile terminal increase, its power consumption also increases, and it usually needs to be charged by a charger. In the existing charging technology, when the mobile terminal is connected to the charger, the charger uses a fixed charging method to charge the connected mobile terminal, such as high constant voltage charging, which will reduce the charging voltage of the mobile terminal. The mobile terminal has a certain impact, thereby reducing the service life of the mobile terminal. Contents of the invention [0004] The technical problem to be solved by the e...
