This is a question that many mobile phone owners have been wondering about. In fact, it has a relationship with the charging head and also with the data line. The two complement each other.

We all know that the charging speed of the mobile phone is closely related to the charger, and the charger is composed of the charging head and the data line. So the charging speed depends on the charging head or the data line. So when there is a problem with the charging cable or the charging head , the charging of the mobile phone will not be slowed down due to the wrong selection only by figuring it out.


The regular charging head is marked with voltage and current output. When charging the mobile phone, the charging head determines the voltage and current. For example, your mobile phone supports a 5V/2.4A charging head. When your charging head is broken, you change to a 5V/1A, the data line does not change, but the charger power becomes smaller, and so does the charging speed. Also, when you buy a new charging head, you should pay careful attention to whether it supports fast charging.


So why does the data line also affect the charging speed?
The data line is used to connect with the mobile phone charger and transmit current. The copper core thickness and length of the data line will directly affect the data line transmission rate. The longer the data line is, the slower the current runs, and so will the charging slow. Otherwise, the faster the phone charges. At present, the line of Micro USB interface on the market generally transmits 2A, but there are also some charging lines without a signal core, which can only be charged and cannot be used to transmit data. All fast charging can be achieved only when the charger is matched with the corresponding fast charging data lines.
