The embodiment of the invention discloses a terminal and a current test method of the terminal. The terminal includes a built-in battery, a terminal mainboard, a first power supply circuit, a second power supply circuit and a USB type-C interface. One end of the first power supply circuit is connected with the built-in battery, the other end of the first power supply circuit is connected with theterminal mainboard, and the first power supply circuit is connected with a switching element in series; one end of the second power supply circuit is connected with the USB type-C interface, and the other end of the second power supply circuit is connected with the terminal mainboard; the USB type-C interface is used for supplying power to the terminal mainboard through the second power supply circuit when an external power supply is connected and the switching element is turned off. Since the external power supply can be connected with the terminal mainboard through the USB type-C interface,the first power supply circuit is provided with the switching element, when a current test needs to be conducted, the external power supply is connected, the switching element is turned off, the powerof the terminal mainboard can be supplied by the external power supply instead of the built-in battery, and the purpose that the power consumption current of the whole terminal is accurately detectedwithout dismantling the built-in battery is achieved.
Description
technical field [0001] The invention relates to the technical field of mobile terminal equipment, in particular to a terminal and a current testing method for the terminal. Background technique [0002] As consumers have higher and higher aesthetic requirements for the appearance of mobile terminals such as mobile phones, in order to improve the smoothness of the overall lines of the terminal and reduce the overall thickness, most terminals (especially high-end mobile phones) currently use non-removable batteries. design. However, this non-removable battery design may cause problems in product production testing, research and development debugging, etc. in some cases. Carry out the standby power consumption current test of the whole machine. To perform this test, the built-in battery of the mobile phone is required to be removed, and the whole mobile phone is connected to an external power supply. For assembled mobile phones with a non-detachable design, this test cannot b...
