Abstract: The present disclosure provides a charging method and a terminal. The method includes: automatically learning, by the terminal, historical data by using a machine learning algorithm, to establish a habit model of a user, and matching a current time with the usage habit model of the user to determine a current charging intention of the user, so as to determine a charging mode according to the charging intention. By means of the technical solutions, a charging requirement of a user can be effectively identified, and on-demand charging can be implemented. This improves user experience while avoiding a battery life decrease caused by frequent fast charging.

Abstract: A charging method, a terminal, a charger, and a system, includes: obtaining, by a terminal, a charging mode supported by a charger connected to the terminal; when the charging mode supported by the charger includes an open-loop fast charging mode, detecting, by the terminal, whether both the terminal and the charger are in an open loop state; when both the terminal and the charger are in the open loop state, sending, by the terminal, an open-loop fast charging instruction to the charger; and receiving, by the terminal, a voltage and a current that are transmitted by the charger according to the open-loop fast charging instruction, and performing charging in the open-loop fast charging mode. When determining that the charger supports charging in the open-loop fast charging mode, the terminal is adjusted to the open loop state to perform charging, so as to shorten a charging time and improve user experience.
