Who has changed the tail plug by himself, is it simple, and how much does it cost to change the tail

If the location of the mobile phone charging port is damaged, it is recommended that you bring the machine, purchase invoice, and repair card to the local Samsung after-sales service center for inspection, and the on-site engineer will help determine how to repair it and whether it is within the scope of the warranty.

If you can't change it, you can directly replace all of it at the bottom and plug the circuit board at the end.

If your device has a hardware failure, in order to reduce the loss, it is not recommended that you disassemble the device by yourself, if there is a problem with your Samsung phone, please send the device to the service center for testing and judgment by a professional engineer.

The tutorial for replacing the tail pin is as follows:

1. Before starting to work, remove things such as mobile phone batteries and mobile phone cards, memory cards, and then use a screwdriver to remove all the screws on the back shell.

2. After removing all the screws, use a screwdriver to slowly pry up the back shell along the surrounding sides until the back shell is taken off.

3. The inside of the mobile phone after removing the back shell is as shown below, and the protagonist we want to replace today is the tail plug at the bottom.

4. There are two screws on the tail plug that need to be removed, and there is also a signal cable, we use our hands or tweezers to gently buckle it up (try to use tweezers, I mainly didn't find tweezers so I used my hands).

5. Unscrew the two screws, and then gently remove the tail plug on the phone.

6. After removing the tail plug as shown in the figure below, prepare the tail plug to be replaced, and prepare to replace it.

7. There is a row of interfaces on the tail plug, that is, the two in the figure below, and they must be carefully fastened together when installed.

It doesn't cost much to replace the tail plug. It depends on whether the store is black or not, and it is generally enough for a few dozen dollars. Of course, this is only a case where the tail plug is broken, and there are no other problems. If there are other questions, I will talk about it separately.

That is the point inside the small opening of the charge.

It is the socket that your phone charges and the cable it is connected to.

The charging tail plug of the mobile phone can be replaced if it is damaged, and it can be replaced directly at the local after-sales service or repair shop for about a few dozen yuan.

Related Notes:The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle. Generally, it is charged with DC current (also with asymmetric AC current or pulse current).

In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or the group inspection round balance charging of these methods.

According to the formula of electricity = voltage * current * time, in the case of fixed power, the charging time can only be shortened by increasing the voltage or increasing the current.
