Huawei passes the fast charge protocol detection method
1. The most common problem in checking the charging port is that there is dust or other impurities in the tail plug of the phone, resulting in poor contact of the charging port.
You can turn on the flashlight to see if there is any impurity attached in the tail plug, and then blow away the dust in the tail plug with the leather, and charge it again to see whether the problem is solved.
Secondly, the loose charging interface will also lead to poor contact during charging and cannot trigger super fast charging.
You can try to shake the charging head while charging to see if there will be a sense of loosening, and observe whether the super fast charge can be triggered during the shaking process. If the cable is loose, replace the original charging cable or replace the rear connector.
2, check the charging head and data cable must use the original charger and data cable, because the current Huawei super fast charger adopts the low-voltage direct charge scheme of SCP, with 4.5V 5A, 5V 2.5A and 10V 4A specifications, so 5A high-current data cable and charging head supporting SCP protocol are required. The ordinary charger and data cable is not up to this standard, naturally can not trigger the super fast charge.
Huawei uses the following methods to check the fast charge protocol:
one
Look at the logo on the charger \"Communication standard YD\/T 1591\" Mobile phone Charger and interface technical requirements and test methods \"clearly stipulates that the DC input voltage of the charging interface of the mobile phone is 5V±5%, and the maximum absorbed current is 1800mA. So as long as the output of the adapter breaks through this condition, it can be regarded as fast charging.\"
two
By actually recording the phone charging time. According to my own experience, if you start charging when the power is 0~10%, after half an hour or so, the phone's power can be basically restored to about 60%, and you can basically judge that your smartphone has fast charging ability.

In addition, you can also go to the corresponding mobile phone's official website and consult customer service, of course, offline sales staff can also be.
four
Download an app called Ampere to see your phone's charging temperature, voltage and whether it has a fast charge.
