Super fast charge becomes slow charge due to the following reasons:
1, it is possible to change a charging cable, charging will be slow.
2, the charging temperature is too high, the battery temperature will be higher than a certain value, so that the charging current will gradually decrease, so that the charging speed will slow down, resulting in a decrease in the charging speed.
3, the data cable interface can not be fully plugged into the phone, so fast charging may enter the ordinary charging mode, resulting in slow charging.
4, working in a dusty environment, the phone is exposed for a long time, resulting in dust into the charging interface. If you often put the phone in your pants pocket, and the charging port faces down, it is also easy to let the charging interface of the phone into ash. After the dust enters the mobile phone, it is easy to block the charging port, resulting in poor charging contact, which will also make the mobile phone charge slowly.
The reason why your super fast charge line has become a slow charge, this may be because your power adapter is not a fast charge power adapter, so it may lead to a fast charge into a slow charge, there is another situation, that is, there is a bug in the software of your mobile phone, after connecting to the power supply, the system identification error will identify your fast charge line as a slow charge line, so, It will not be fast charging this case, it is recommended that you repeatedly plug and unplug attempts
The super fast charge cable is slow for the following reasons
< br >
First of all, excluding the charger is broken and the charging cable is broken, I personally think that the reason for the super fast charge is slow, mainly because the jack contact is too weak, as long as there is a place where the interface is inserted, the speed will be slow.
