The reason why the data line of mobile phone can't transmit data while charging
First of all, make sure what model your mobile phone is and what operating system you use. Generally, it is mentioned in the user manual of your mobile phone, and the corresponding instructions can be found on the Internet. Let's search for it.
In the power on state:
If it is a non intelligent system mobile phone, some mobile phones need to manually set the USB data connection in the mobile phone after connecting to the data line, in order to successfully connect the data between the mobile phone and the computer. In addition, some mobile phones need to install the management software in the driver CD attached with the mobile phone in advance to connect successfully. If it is a smart phone system, most of them only need to connect to the data line, and a small number of them need to install the management software attached with the note in advance.
Please rule out three reasons
1. The power supply of USB interface is insufficient, resulting in unrecognizable, or the driver is not installed, or your Windows operating system is a compact version, lacking necessary components. If there is no problem before, it should not be the business of the operating system.
2. Poor contact or damage caused by internal soldering or looseness of USB port of mobile phone.
3. Data line using exclusion method, if the maintenance, the cost will be a few yuan, mobile USB port problem, the cost is also a few yuan, really can't buy our mobile data line.
