  "textContent": "This application provides a power supply system and method for a terminal device, a chip, and a terminal device, and relates to the charging field. The power supply system includes a battery pack, a bypass circuit, a voltage step-down circuit, and a controller. The battery pack includes at least two batteries. An output end of the battery pack is connected to an input end of the voltage step-down circuit, an output end of the voltage step-down circuit is connected to a power consumption element of the terminal device, one end of the bypass circuit is connected to the input end of the voltage step-down circuit, and the other end of the bypass circuit is connected to the output end of the voltage step-down circuit. The controller is configured to: when the batteries in the battery pack need to be switched to a series mode, control the voltage step-down circuit to work and control the bypass circuit to stop working, and is further configured to: when the batteries in the battery pack need to be switched to a parallel mode, control the bypass circuit to work and control the voltage step-down circuit to stop working. In the system, switching between the series mode and the parallel mode can be automatically implemented based on an actual situation, so that endurance can be increased while stability of the terminal device is improved.",
