How should we solve the problem of poor contact with the charging port of the mobile phone?

Method 1:First determine if it's a problem with the charging power source. Connect the data cable to the mobile phone and the computer, if it shows that the charging is successful, it is a problem with the power head, try to charge it with a different power head, if the charging fails, change the phone data cable to try to be cautious.

Method 2:If the charger is good, then it must be a problem with the mobile phone, and it is more likely to be the reason for the charging interface (tail plug).

You can check whether the charging port of the mobile phone is blocked by foreign objects or whether the liquid is loose, turn off the mobile phone and wipe it with a cotton ball dipped in alcohol, and then try to turn it on.

Method 3:First of all, use a browser to search for Xiaomi's official website and click to enter, after entering the official website, slide the mouse wheel to the bottom, search and select a Xiaomi official maintenance point closest to your location, and finally bring your mobile phone and mobile phone's charging equipment directly to customer service or repair shop to change the charging interface.

1.Abnormal usage environment:

If the mobile phone is in an extreme environment (such as when the ambient temperature is too low), the mobile phone may not be charged and turned on normally, so it is recommended to move the mobile phone to a normal temperature environment and use the original adapter and data cable for charging.

If the phone automatically shuts down due to low battery, it may not turn on when the charger is plugged in and the LED light will be on.

Flashing, it is recommended to charge for 15-30 minutes, open up in the morning, and try to turn on again.

2.Adapter is abnormal or in poor contact:

If there is no response or abnormal charging after connecting the mobile phone to the adapter, you can check whether the connection between the adapter and the socket, the adapter and the data cable, and the data cable and the mobile phone has any poor contact, such as whether the adapter can be used to charge other devices.

Some power adapters.

There may be compatibility issues, in case of failure to charge normally, it is recommended to use the original adapter and data cable to charge the phone.

3.System Exception:

Some specific system versions may have the situation that the phone will not charge or cannot be charged. If you encounter this problem after upgrading the system or flashing the computer, you can try to restore the factory and enter Recovery to clear the data.

4.Hardware failure:

In the daily use of the mobile phone, the charging head is repeatedly plugged and unplugged, the mobile phone into the ash, liquid ingress, bumps, drops and vibrations, cold and hot environment impact and other factors may cause the mobile phone not to charge or abnormal charging, if the mobile phone is still unable to charge normally according to the above method to replace the environment, adapter, data cable, etc., it is recommended to bring the mobile phone and the original adapter to the after-sales outlets for testing and processing, and the final result is subject to the after-sales testing.

Possible Causes:

1.Faulty charging equipment. For example, if the data cable or charging head is abnormal, replace the test separately.

2.Battery failure. For example, loose, deformed, etc., replace the battery.

3.Software glitches. Generally, flashing can be solved.

4.Hardware failure:For example, the charging interface has poor contact, and it will be sent for repair.

5.Failures in other areas. For example, there are too many soft training disassembly parts running in the background, resulting in the input being less than the output, causing the phenomenon of non-fluttering charging.

The reasons and workarounds for this situation are:

1. The Xiaomi charging indicator keeps flashing red and can't turn on, which means that the phone has run out of power and will automatically shut down when it is used. If the battery is too low, it will automatically shut down and the battery will go to sleep. The battery can be removed, and after five minutes, it can be turned on when it is connected to the charger and charged for more than half an hour.

It can be charged by connecting to a charger. During this process, the mobile phone LED may not light up at first, and after a few minutes, the red light of the LED starts to flash and gets faster and faster, and it can be turned on when the red light is no longer flashing and is always on.

2.If it still can't be repaired, please go to the nearest repair station as soon as possible to inspect and repair.

It is recommended not to charge the mobile phone until it is automatically turned off when in use, and it is best to charge it when the mobile phone prompts a low battery, which is conducive to the maintenance of the mobile phone battery.

Solution to poor contact of Xiaomi charging interface:

1. To determine whether the charger is good, you can try to change the charger.

2. If the charger is good, it must be a problem with the mobile phone; This 90% probability is due to the charging port (tail plug):

1) You can try it by yourself, turn off the phone, take out the battery, prepare a little cotton dipped in alcohol, and then use tweezers to clamp the cotton to clean the lower interface;

2) After cleaning, wait for 1-2 minutes (the alcohol volatilizes quickly and will not be short-circuited) to start up.

3. If the second method still doesn't work, just go directly to customer service or repair shop to change the charging interface.

If you find that the keys of the mobile phone interface are loose or have poor contact, and it affects the daily use of the mobile phone, it is recommended that you take the mobile phone to our after-sales service center for professional and technical personnel to test and deal with it for you.

If the mobile phone is not fully charged for a long time, please first confirm whether the original charger used to charge the mobile phone and whether there is any poor contact of the charging interface. Also, try not to use your phone while charging.

If you use a power bank with a lower output current to charge, the charging time will also be extended, so you can replace the power bank with a slightly larger output current for charging. If it still can't be solved, it is recommended that you bring your mobile phone to the after-sales service center for testing and processing.

According to my current experience, it is a reason that there is a problem with the tail plug of the mobile phone, and the tail plug should be replaced if it is serious; If it's not serious, it can be solved by changing the data cable. Some people also said that they went directly to the place where the phone was repaired and asked him to connect the cable for you, but I didn't figure out how to connect it, and this is more reliable than changing the tail plug.

What else can it do? If there is a seat charger, use the seat charger to charge, if you don't have it, you can only repair it.

Hi! It is recommended to go to the after-sales service.
