The phone can t be charged, what s going on?

If you are using a vivo mobile phone, how to handle charging exceptions:

1. Check whether to turn on the "Optimize Battery Charging" function: Go to Settings - Battery - Charging Settings to see if the "Optimize Battery Charging" function is enabled, the phone cannot be fully charged after the function is turned on, you can turn off this function and try;

Note: If the phone does not have this switch, it does not support this function.

2. There is a problem with the battery level display: turn off and restart, check whether it returns to normal;

3. Whether to use the original charger and data cable, you can replace the charger and data cable;

4. Check whether the charger and socket are in good contact, and try to replace the socket;

5. If the mobile phone exceeds or falls below a certain temperature value, it may not be able to be charged, so try to change the charging environment;

6. Bring your mobile phone to the vivo customer service center for processing, it is recommended to contact in advance before going to avoid empty running, plan your itinerary reasonably, and travel safely.

Customer service center address: Enter vivo official website vivo**app--my--outlet query or vivo official website web version--bottom of the bottom -- service support--service outlet inquiry--select the province and city to query the customer service center address.

The phone cannot be charged, check the charging port and data cable.

There are also several cases: 1 the battery is damaged, 2 the contact is bad, 3 the charger is bad, 4 the charging IC and the charging circuit are not working properly;

To check one by one, charge first with universal charging, if it can't be rushed, it means that the battery is a problem, replace the battery; If the universal charger can be charged, it means that the battery is fine, and the charger and charging circuit need to be checked; Try to reconfigure the charger, if it is still not good, it means that the charging IC or charging circuit is not good, and some parts need to be removed or the IC needs to be replaced. The latter is expensive to repair, and other results do not require repair.

If the phone can't be charged, don't fix it, come and learn this trick.

Try a few more times It may be that the data cable is broken Generally, the mobile phone is not broken when charged at least 500 times It is recommended that you change the data cable.

The reason why it can't be charged is generally because the electromagnetic is broken.

If you are using a Huawei phone and the phone cannot be charged, you can follow the following methods to determine the cause of the problem:

1.Please use an officially recommended charger for charging.

It is recommended that you use the charger and charging cable officially recommended by Huawei for charging. Non-Huawei chargers and cables may not be compatible with the phone, resulting in the phone not charging.

2Please check the device and ambient temperature.

Charging the phone when the ambient temperature is too high or too low may trigger the battery charging protection mechanism and cause it to fail to charge normally, please make sure to charge the phone at 1 35°C.

3..Please check if your phone has not been used for a long time.

If your phone has not been used for a long time, or you have not charged your phone in time after the low battery is turned off, it is recommended that you charge it for more than 30 minutes to check if the phone responds.

4.Please check whether the charger and device interface are abnormal.

When the charger and cable are damaged or the mobile phone charging interface has foreign objects or deformation, etc., it may cause the phenomenon that the connected charger cannot be charged, please make sure that the charging port is clean and free of deformation before charging, and check whether the charger and cable are damaged, and you can replace other chargers.

Huawei Customer Service Center.

Repair spare parts** inquiry.

Boarding service.

First of all, replace the charger of the mobile phone, now the mobile phone charger is basically universal, change one to see if it can be charged, if it still can't, you can rule out the reason for the charger.

If there is a spare battery, replace the battery to see if it can be turned on and charged, if it still can't be turned on, it is likely to be a problem with the mobile phone, and it should be sent to the after-sales service for testing and repair; If it can be turned on and charged normally, it is a problem with the battery.

At this time, you should observe the positive and negative electrodes of the battery that can not be charged, to see if there is a metallic luster, the battery may disappear in a high temperature and humid environment for a long time, resulting in conductive problems so that the machine can not be turned on.

It still can't be charged, it means that the mobile phone battery has entered a state of self-protection, and it needs to be activated at this time.

If it is too troublesome, you can also use the following methods to activate: find a universal charger, preferably the kind that automatically identifies the positive and negative poles, charge it for 5 minutes after connecting it, and then take it off and install it on the mobile phone and then charge it directly, which can generally be activated at this time.

1. The power of the electrical appliance is too large, which may damage the plug board, so you can check the charger at this time.

2. If the charger is used for too long, it is easy to cause the connector to break, if there is no problem with the plug, check the charging cable. 3. If there is no problem with the charging plug board and charging cable, it may be that the old battery and internal circuit board of the mobile phone are out of order.

4. There is a problem with the mobile phone battery. Generally speaking, it is rare to have problems with your phone's battery. But once there is a problem, it is a big problem and must be taken seriously.

5. Therefore, when it is found that the charger and mobile phone system are not faulty, the battery should be checked. If you find that the battery is swollen, then it means that there is a problem with the battery and you must stop using it immediately.

If the mobile phone is a lithium battery, frequent charging actually has certain benefits for the battery.

There is a saying: every mobile phone battery has a fixed number of charges, if the number of charging times is too much, it will accelerate the degree of battery aging and strain! This practice is actually only a practice on nickel batteries, lithium batteries are different, and frequent charging is actually beneficial to the battery.

When the phone battery is too low, you should start charging in time.

It turns out that the phone battery is more "happy" if it is charged multiple times a day, rather than when the battery runs out. When the power loss is 10%, the effect of the side slag in charging the mobile phone is the best. Obviously, this is impractical for most people, so plug your phone into the charger when you can.

It is a good habit to charge multiple times a day. Not only does this help extend battery life, but it also helps keep your phone charged throughout the day. In addition, regular charging allows users to use special offers that are not normally used due to high power consumption, such as positioning-related features that utilize smartphone GPS (Global Positioning System (GPS) antennas.

Other charging misunderstandings of mobile phones:

1. Don't pay attention to the temperature when charging.

In a low-temperature environment, the low-temperature protection mechanism of the lithium battery will promote the chemical reaction of substances in the battery, so it cannot be charged or the charging speed is slowed down, and at high temperature, the lithium battery will be unstable and even cause **.

2. The new phone needs to be activated.

A new phone needs to run out of power and then charge it, and it needs to be repeated 3 to 4 times, which is called activation. In the past, mobile phones needed to do this, but now lithium batteries are no longer needed.

The reasons why the mobile phone can't be charged and the ways to solve the hailstorm: mobile phone system failure, charger failure, poor contact between the charger and the mobile phone, mobile phone battery problems, and problems with the mobile phone itself.

1. Mobile phone system failure

The phone cannot be charged, it may be caused by the system failure of the mobile phone, the solution is to turn off the mobile phone directly, and then restart the mobile phone to see if the mobile phone charging is back to normal.

2. The charger is faulty

If there is a fault in the charger for charging the mobile phone, it will also cause the mobile phone to not be charged, the solution is to change to other chargers with the same interface to try charging, if it can be charged normally, then it can be determined that it is a problem with the charger, and a new charger can be replaced.

3. The charger is in poor contact with the mobile phone

At this time, the data cable and the mobile phone are unplugged and reconnected, and the data cable and the charging head part are also unplugged and reconnected, and the charging head and the data cable are plugged in with the mobile phone before they can be charged normally.

4. Mobile phone battery problems

Under normal circumstances, the probability of mobile phone battery failure will be relatively small, but once the battery has a problem, it must be caused to rot or our attention. If there is no problem with the phone charger and the phone system, then you need to check the phone's battery;

If you notice that your phone's battery is swollen, it means that there is a problem with your phone's battery, and you should stop using it immediately. At the same time, the battery cannot be disassembled by itself, so as not to swell the battery, which will bring more serious consequences.

5. Problems with the phone itself

If none of the above solutions can solve the charging problem of the mobile phone, it may be because there is a problem with the mobile phone itself, and the mobile phone needs to be sent to the nearest after-sales repair center for testing and repair.

If you are using a vivo mobile phone and the mobile phone cannot be charged, you can check it according to the following methods:

1. Check the charger and data cable.

2. Check the charging port of your phone.

Check the mobile phone charging port for foreign objects, corrosion, dirt, liquids, etc., if there is such a phenomenon, please go to the vivo customer service center for testing.

3. The mobile phone has not been used for a long time or is over-discharged.

If the phone is not used for a long time or the battery is automatically turned off, the battery is in an over-discharged state, it is recommended to charge it for 30 minutes before checking.

4. If the phone stops charging when it is charged to 80%, please check the function settings of the phone.

Some models are supported"Optimize battery charging"function, if this function is turned on, in order to prolong the battery life, it will intelligently learn the historical charging habits of the mobile phone, and intelligently adjust the battery full time when the mobile phone is charged for a long time.

Note: Go to Settings - Battery - More Settings Charging Settings - Optimize Battery Charging - Turn on Off Function, if you can't see this menu, it means that the machine does not support this function.

5. The charging environment temperature is too high or too low.

If your phone exceeds or falls below a certain temperature value, you may not be able to charge. In order to ensure the safe use of the battery, the battery cannot be charged when the temperature is lower than 0, the system will prompt "The temperature is too low, charging has stopped", which is the charging protection mechanism of the battery, it is recommended to charge the battery in the environment of 0 35.

If the temperature is high, it is recommended to leave the phone in a slightly cooler environment for a period of time before charging.

6. Service center testing.

The phone cannot be charged, and you can solve the problem by taking the following measures:

1.Battery undervoltage: When your phone's battery is too low or has not been charged for a long time, charging may become slower or even impossible to charge.

This is due to the chemical reactions inside the battery that can cause the battery voltage to drop, which slows down the charging rate. At this time, you can charge it for a while and try it.

2.Faulty charger: If you're using an original charger and the charger fails, it can also cause your phone to not charge. Therefore, you can try replacing the charger or contact the charger manufacturer for service.

3.Damaged mobile phone interface: If the mobile phone interface is damaged or dirty, it may cause it to fail to charge properly while charging. You can use a cotton swab or a soft cloth to gently wipe the phone connector to clean any dust or dirt.

4.Damaged charging cable: If you notice damage to your charging cable, it may also prevent your phone from charging. If you're stuck, try replacing the charging cable or contact the charger manufacturer for service.

5.Phone system failure: If your phone system fails, it may also cause the phone to fail to charge. You can try restarting your phone and check if the system update has been completed.

If the above methods still do not solve your problem, it is recommended to contact the phone manufacturer or after-sales service center to repair or replace the charger.
