There is nothing wrong with the charger, charging speed. At present, the mobile phone basically supports the ordinary fast charging function of 5v2a, and the speed of 1.5a will be slower, which does not reach the charging limit of the mobile phone. Of course, the speed of 1.5A depends on whether the data line meets the speed above1.5a. In fact, the reduction of the current speed of the data line has a great influence, which is much greater than the output current of the charging head. The current limit of many data lines is only about 0.8a A good data line is about1.7a. When measuring more than 20 data lines at home, only one third of the data lines reach the speed of 1.5A or above.
In addition, it should be said that high current charging is not a good thing. The faster the charge, the greater the heat, and the faster the battery cycle life decreases.
1.5a current, very suitable for sleeping at night and charging for a long time.
