What should I do if the mobile phone charging cable doesn't respond?

1. The phone has no power at all, but the charger doesn't respond. What happened?

The mobile phone can't charge. Solution:

The first point: Because we are used to putting the mobile phone in our trouser pocket, the charging interface at the bottom of the mobile phone is easy to accumulate dust, which leads to poor contact between the interface and the power cord plug. So, when the phone can't be charged, please check whether the interface at the bottom of the phone is blocked by foreign objects.

The second point: If there is no problem with the power interface of the mobile phone, you can replace the charger and power cord that you usually use by replacement. If you have a computer with you at this time, you can plug your mobile phone into the USB port of the computer to see if it can be charged normally. If it can be charged, there is something wrong with the charger.

The third point: If the phone can't be charged when connected to the computer, you can borrow the power cord of someone else's Apple phone at this time to see if it can be solved after changing the cord. If changing the line can solve the problem, it means there is something wrong with the line. Replace the power cord at this speed.

Fourth point: If all the above methods fail, you can try to turn it off and on again. Sometimes it may be due to the system, which makes the mobile phone unable to charge. In addition, there is the problem of temperature. Because of its physical characteristics, the battery is particularly sensitive to temperature. Too high will cause problems, too low will lead to no charge. Of course, this situation is limited to places where the temperature is particularly low in winter. If the battery cannot be charged due to this problem, please put the mobile phone on the bed or in the air-conditioned room first, and then charge it.

Fifth point: If the above methods can't solve the problem, it is necessary to recall whether the mobile phone has been flooded or dropped. Because water or falling may damage the internal parts of the mobile phone, it can't be charged. Of course, it may also be other circumstances. Anyway, there may be a hardware failure in the mobile phone at this time. It is recommended to repair the mobile phone to an authorized service organization for testing.

2. There is no response when the mobile phone is plugged into the charger. What happened? Another Meizu charger still doesn't respond.

Causes and solutions of no response of mobile phone charger: 1. The internal circuit board of the mobile phone charger is damaged, and the charger does not output electricity. You can replace a charging head or charging treasure first to see if it can be charged.

2. The data cable is damaged, usually the core inside the data cable is broken. Find a similar data cable instead and try charging. 3. If the above two reasons are not true, it is that the small board circuit inserted in the mobile phone or the charging management chip of the motherboard is broken. This problem can't be handled by ordinary people, so we can only find a professional mobile phone repair point to deal with it.

Extended data Most people think that the biggest key to purchasing data cables is price. Actually, this is the biggest misunderstanding. As I said just now, data cables are divided into domestic brands and domestic unlicensed ones according to manufacturers. There are unlicensed and miscellaneous brands in China, and the quality is really poor. One of the three lines 1 is broken, which makes customers constantly doubt that their computer level is too poor. How can they put them on the computer to deny it? Therefore, it is the key factor to distinguish the quality of products and find good sellers.

More powerful sellers are generally the guarantee of product quality, because they don't want the data cable they sell to be returned, not to mention the round-trip postage, even if it takes a lot of time and energy. Therefore, gold medal sellers will cooperate with well-known and reputable manufacturers. The defect rate of these manufacturers is generally 1%, while that of some bad manufacturers is 30%.

This is why the price difference of the same model and the same function data cable is 2 times. Even with the same data cable, buyers enjoy different prices and services in different manufacturers. The high price may be accompanied by a series of services such as free testing, technical consultation, website download, free replacement and installation guidance. Why is the price of coffee bar higher than that of tea shop? It is the same reason that service and grade are different.

3. What happened when the mobile phone charger didn't respond?

Check the cause and solve it:

1, the current output is not enough or the plug is inserted incorrectly: this usually happens when charging through the computer. Because the output of u *** is small, it sometimes leads to the phenomenon that it cannot be charged, or the plug is not plugged in properly when charging, thinking that the mobile phone is charging, but in fact the mobile phone is not charging. Pull it out and reinsert it in another place.

2. The charger and the data cable connector are broken or the interface is dirty and cannot be charged: you can change the charging head. Or take a thin piece of metallographic sandpaper and cut it to the right size. After folding it in half several times, gently polish it a few times at the data cable interface, and then plug it in for charging.

3. The battery or battery interface of the mobile phone is damaged: after the above reasons are eliminated, if you suspect that the battery or charging interface of the mobile phone is damaged, please go to the after-sales inspection and maintenance.
