Mobile phone often power off during the charging process, possible causes and solutions:
1, the socket may be poor contact caused by intermittent charging problems, it is recommended to replace the charging position to try;
2, it may be the charger problem, if the conditions allow to replace the original charger and data cable for testing. Or send to repair test;
3. When charging, if the phone is equipped with third-party battery management software, it is recommended to uninstall and test;
4, check the mobile phone charging interface whether there is foreign matter, such as liquid, there is debris resulting in poor contact between the mobile phone charging interface and the charger, if this is the case, it is recommended to send for repair as soon as possible;
5. Backup the phone data and restore the phone to factory Settings;
6, if the above methods can not solve the problem, it is recommended to go to the local customer service center for testing and maintenance.
It may be unstable charging caused by poor contact of the socket. Ensure that the strip can output power normally, and try to replace the strip for use. If the charger has a problem or hardware failure, you can change a charging cable to charge it. If it is a problem with the mobile phone system, the phone can be restored to factory Settings and then charged, or directly shut down to charge. If it is the reason of the mobile phone charging port and the battery, it can only be repaired after sale
When the mobile phone is charging, the automatic power off, the reasons are generally several: 1, the charging control circuit is faulty; 2, the charger is faulty; 3, poor interface contact; 4, the battery performance is close to failure.
According to the phenomenon you described, there are only two reasons: 1 is the charging head is broken (whether it is the original or it brand, the charging head is used inside the resistance, capacitor step-down rectification, and then voltage regulation into 5V power supply, the advantage is small size and large current, the current can reach 1-1.5A; The disadvantage is that the performance is not good, the voltage is unstable, and if the capacitor breakdown is possible to damage the phone); 2 is that the battery has failed, has not reached the nominal voltage and capacity.
You can verify that the method is to plug the phone into the computer or use the switching power charger (that is, the old big charger with USB interface) on the charge, if the power is constantly, then it is the problem of the original charger, on the contrary, if the fault is still, then the battery has failed. It is recommended that when charging the mobile phone, you should try to choose a switching power type charger, but the charging current should be controlled below 0.5A, so that the phone can avoid hot charging, but also to extend the life of the battery.
There are several reasons why cell phones keep charging and losing power.
The first point may be that the charger is damaged, and the charger damage is most likely to lead to charging and power off.
The second is the mobile phone battery damage, if the battery is broken, it may also cause charging and power off.
There is also a possibility that the mobile phone motherboard is broken, which will also lead to charging and power off. So if you meet this situation, it is best to find a professional after-sales service check.
1. The data cable is broken.
2. If the phone has been charging, it is always powered off if it is not fully charged, I personally think this is caused by a broken data cable. Many people are particularly easy to break the plug of the data cable, and can not be seen by the naked eye, but when charging it can not be charged, this time you can take someone else's data cable to try, if no problem, it means that the data cable is really broken, you need to buy a new one.
There are several possible reasons why the phone has been charging and the power has been cut off:
First, there is a problem with the data line, the wire is broken and the contact is poor, and the current sometimes passes through and sometimes breaks.
The second is the aging of the charger, which is overheated when charging, and the situation can not be charged.
Third, the third-party charging software app installed on the phone is improperly set, and it cannot be charged.
Fourth, the smart charging Settings of the mobile phone system fail, and the mobile phone system needs to be restored.
It may be that the contact between the charger and the mobile phone is poor. You can see whether the interface is aging, or you can go to the mobile phone repair shop to see if you can clean it up. Sometimes this situation will occur when the interface is aging, and this situation will occur when the mobile phone is used for a long time.
Now the technology has been very developed, the modern mobile phone is different from the previous mobile phone. In order to protect the mobile phone battery, the mobile phone battery automatic protection device is set. When your phone is charging, if it has been charged to the phone, it will automatically power off, and then the phone will continue to charge again. That's why we have the situation you're talking about.
Your mobile phone has been charging and power off, indicating that your battery is broken, the battery of this mobile phone has been used for too long, you can change a new battery, this must be a broken battery, the battery of this mobile phone can generally be used for 2 to 3 years, if it is used for a longer time, then it is certain that the battery will be broken, this a main workshop is not able to flush, A little rush means he he feels full and says he's going to cut you off, and then after a while he's going to restart you again and again and again and again and again and again.
Now we all use smart phones, it is really very convenient, many functions are also very practical, such as listening to music, reading novels, watching videos, chatting wechat, payment and so on. But smartphones are also a drain on battery power because features are always used and the screen is always on.
So now many of us go out with chargers, charging treasure, and there will be charging and power off in the process of charging, which has several possibilities. Generally, when we sleep, we will charge the phone and put it aside, and when it is full, it will automatically power off after a period of time. There is the mobile phone battery is broken, or the charger is faulty, and there is a problem with the charging interface of the mobile phone, which will cause such a problem.
How is it that the phone has been charging and the power has been cut?
Relatively speaking, if we charge our mobile phone, if you have not unplugged it, it will not charge after it is full, it only has this thing it will automatically stop, a smart stop does not need us to turn off, this is. For an explosion, so he will not always charge, it has a discharge function, as long as it is full of it will be cut off.
Talk about my personal point of view: mobile phone has been charging power off what is going on?
According to your question is my opinion and understanding; It is possible that your mobile phone charging port is broken and needs to be repaired. Or maybe there's something wrong with your charger that's causing the power outage. There may also be a problem with your mobile phone motherboard, which may also lead to charging and power failure.
The mobile phone has been charging, it proves that the battery is not good, it does not take long to be fully charged, it is out of power again, so you have to quickly return the charge, if this is particularly serious, you have to change the mobile phone, buy a mobile phone must buy a brand, so the battery life is long, and the mobile phone after-sales warranty is guaranteed, you can not buy miscellaneous brands of goods, if it is more troublesome to use,
The mobile phone is used for more than its life or use cycle, that is, the battery is not used, the general mobile phone can be used for two or three years is good, two or three years later, the lithium battery of the mobile phone will be damaged, if you do not change the battery, the mobile phone is basically used for a mobile phone, the new mobile phone, the battery can be used for one or two days, but the more it goes to the back. After a year or two, the phone's battery may only last a morning, and then less
In this case, do you first rule out your charger problem and see if it is caused by your charger problem? If it is not caused by the charger problem, this situation is replaced
