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.
