Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a test system and a terminal. Background technique [0002] With the improvement of hardware performance and the reduction of price, consumer electronic products have become more and more popular. For the sake of portability, mobile terminals such as smartphones, cameras, and tablet computers are equipped with batteries so that they can be used without an external power source. The battery is typically a lithium-ion battery with a high energy density. In order to avoid the inconvenience caused to users by power depletion, these devices generally provide a power estimation function. For example, the operating system of a smart phone can provide the user with information on the remaining battery power displayed in percentage, so that the user can charge it in time when the power is low. [0003] However, the inventors of this patent application h...

Problems solved by technology

However, the resistance value of the power calibration resistor is small, the resistance of the solder cannot be ignored, and there are tolerances in the power calibration resistor at the factory. It is not accurate enough, the battery jumps, even when the battery is not exhausted, the software will judge to shut down
