Abstract

The invention discloses a method and a terminal for intelligently detecting adapter performance, comprising steps of, under an adapter performance detection mode, obtaining no load voltage U1 of the adapter and practical working voltage U2 on two ends of a loading resistor after the loading resistor is loaded on the power supply output terminal of the adapter through sampling, and determining the performance of the adapter according the no load voltage U1 and the practical working voltage U2. The invention can determines whether the adapter performance is qualified through respectively sampling the no load voltage U1 of the adapter and the practical working voltage U2 on two ends of the load resistor after the load resistor is loaded according to the no load voltage U1 and the practical working voltage U2, which is quite convenient, prevents the charging circuit of the terminal and the battery from being connected to an adapter with poor performance to shorten the service life of the battery, and greatly improves the user experience for the product.

Description

technical field [0001] The invention relates to the technical field of circuit parameter detection, in particular to a method for intelligently detecting the performance of an adapter, and to a terminal for intelligently detecting the performance of the adapter. Background technique [0002] The popularization of smart phones and the open development of android have led to the rapid development of mobile phones. Not only are fake mobile phones emerging in endlessly, but also fake accessories are everywhere. Usually, it is very expensive to buy better accessories without buying qualified products. Headache. This is the case with counterfeit adapters on the market. After buying the adapter, it breaks down within a few days after returning home, or the performance does not meet the requirements at all, which violates the interests of many consumers. There are many factors that affect the performance of the adapter, such as: the level of technology, the materials used, etc., wh...
