Problems solved by technology

[0003] At present, the connection port of the battery in the terminal is used for charging and power supply at the same time. It is designed on the upper end of the battery, close to the main board of the terminal and away from the USB port. Therefore, as the charging power of the terminal becomes higher and higher, the charging current becomes higher and higher. The larger the , the longer the charging path, resulting in a larger charging impedance and lower charging efficiency

Description

technical field [0001] The embodiments of the present application relate to the technical field of battery charging, and in particular, to a dual-interface battery-powered terminal and a charging method. Background technique [0002] There are two common layout structures for terminals such as mobile phones and tablet computers, namely, upper and lower half-section boards and L-shaped boards. After inserting the charger from the Universal Serial Bus (USB) interface at the bottom of the terminal, for the upper and lower half board structures, the charging path is from the USB port through the Flexible Printed Circuit Board (FPCB) to the The battery connection port, for the L-shaped board structure, the charging path is from the main board to the battery connection port. [0003] At present, the connection port of the battery in the terminal is used for charging and power supply at the same time. It is designed on the upper end of the battery, close to the main board of the t...
