If there is a problem with the charging part of the mobile phone, what should I do if there is a pro

1.Check whether the charger socket and connector part are empty, if it is empty, then it can lead to poor charging, and the situation you described will appear.

2.Check that the small metal connector on the battery is secure with the connector inside the phone.

3.Check if there is too much space between the battery and the phone, and if so, put a few sheets of thick paper between the back cover and the battery.

4.Wipe the metal connector of the battery and the metal connector inside the phone with clean paper, as if there is dust on it, it will affect the use of the battery.

5.Check if there are too many programs in the phone, causing the phone to slow down, the phone is hot, and the power consumption is high.

6.The battery is good, but the battery is at the end of its useful life and it's time to replace the battery. (If that's the case, just change the battery).

7.The problem with the charger, but your one doesn't seem to be possible, because if the charger is broken, no electricity can get in.

8.There is something wrong with the internal circuit of the mobile phone, and it shouldn't be so much.

You try the first few methods first, and if it doesn't work, you can fix it again, and spend one or two hundred dollars on it).

The system misidentified the power of the battery, even if the factory restoration seems to be useless, it is estimated that you have to reflash the system, try to restore the factory handle first.

Check if your phone's battery is not fully charged to the voltage, the phone's display is virtual.

It's either a hardware problem or a software problem. It is recommended to flash the machine.

Method Step sharing: 1. First of all, if you find that the speed is very slow during the charging process, you should check whether the charger used is original, if not, please replace it in time. Although many mobile phone chargers are universal, they will affect the charging time to a certain extent.

2. Secondly, sometimes the mobile phone is completely out of power when it is charged, and there may also be some abnormalities in charging, in this case, it is necessary to be able to charge in time, when the mobile phone body fragrance is less than 20%, it is necessary to charge, which can also ensure the normal use of the mobile phone 3. In winter, for relatively cold places, often the mobile phone will also be abnormal when charging. It is very common for the temperature to be too low to cause no way to charge normally, in this case, it is necessary to maintain the temperature of the room in order to be able to charge effectively. 4. When the mobile phone can not be charged normally, be sure to check whether the plug-in board has power, if there is no power, you must replace the plug-in board with electricity, so as not to reach a certain time, the mobile phone is still in a state of no power, which may affect the normal use of the mobile phone.

5. Of course, there are also some friends whose mobile phone charging abnormalities may be problems with the mobile phone, in this case, it is necessary for professional friends to test and repair the mobile phone, so that it can better ensure that the mobile phone can be charged normally. 6. There are many different reasons for abnormal mobile phone charging, when you find an abnormality, you must first find a specific reason, so that you can have a targeted solution, and at the same time, when charging, you must pay attention to safety, and at the same time do not use the mobile phone frequently, so as to better charge.

I'll tell you, I'm the best at buying mobile phone accessories, this is the reason for your mobile phone charger, your mobile phone charger is 5v1a, it's good to change the charger head to 5v2a, and the mobile phone charging cable should not be too long, some people buy a data cable of about two meters away from the socket at home to supply power to the mobile phone, remember that the longer the mobile phone data cable, the slower the charging, because the line is longer, the current is also reduced, and the resistance value is also larger, and the charging is slow.

It's not a charging cable and power supply issue, it's just.

Problems with mobile phones. The mobile phone is plugged into the charger to supply electricity, and it will not be powered by the battery, and the power will not drop.

It is possible that the maximum input of the mobile phone is only 1A.

Standby charging can be charged. No problem with the phone.

Change to a 5V2A charger without fast charging. Play while charging, no battery will lose power. With a 5V1A charger, if the output is less than 1A, the power may be lost.

When playing with the phone when it is fully charged, it still enters 1A, so it cannot be charged when the battery is not satisfied.

First of all, there is the problem of plugs. The plug of the charger is not only a tool for transmitting electricity to your electronic products, it has very clear specifications, the voltage and current of the charger are all tested by mobile phone manufacturers, and then the most suitable charger with the most stable and fastest specifications for you (of course, except for a few manufacturers, such as Apple......).So once the original charger is broken or lost, buy a new original charger or the same specification as soon as possible. Secondly, there is the problem of ambient temperature, which I believe most people have a deep experience.

In the winter, the battery of the phone is particularly undurable, and in the summer, the battery seems to be getting better again. This is the problem of the working principle of lithium batteries, when the temperature is low, the internal chemical composition of lithium batteries is not active enough, and no chemical reaction will occur, the same reason, in winter or when the surrounding environment is low, charging will become slower. The third reason is that there is dust at the mobile phone interface, although this seems to have no effect, but in fact it will cause poor contact between the charging interface and the charging cable, which will eventually lead to slow charging, and the fourth reason is the problem of the system version.

Because the domestic mobile phone system is updated frequently, there will inevitably be some bugs, and sometimes the slow charging may just be a display problem, which is not too worrying. The above four solutions are: replace the original charger, charge in a suitable environment, clean the dust at the interface with a special small brush, and wait for the new system version to be pushed and updated in time. This is usually the reason why mobile phone charging slows down, I hope this article can be helpful to everyone.

There are many problems with mobile phones that have been going on for a long time, so let's first see if there is a problem with the data cable.

If there is any possibility that it is a problem with the motherboard, the life of electronic products is indeed not long, and the use of maintenance is conducive to prolonging the service life, and it can also be charged before the power is exhausted, and the battery protection is good and can be used for a longer time.

It may be that there is a problem with the battery management system of the smartphone, resulting in a charging mark, but it just can't be charged. In this case, you can remove the battery and reinstall it if you have the conditions, and there is no condition to go after-sales. If the previous operation method does not work, go after sales at this time.

This situation is generally caused by a problem with the charger, data cable, charging control circuit, battery itself, etc. The first two can be tested by replacement. The latter can only be sent for repair.

Or when charging and then losing power, the mobile phone has a large internal consumption or the battery is aging. Turn off the background, don't use it after it's fully charged, and let it go for a day to see how much the power drops, and you can judge.

1. Confirm whether the data cable is normal, the data cable looks normal on the outside, but it may have broken inside;

2. If the battery level is too low, the battery will be protected, which will cause the battery to enter a sleep state, and it needs to be charged for 20-30 minutes to activate the battery before it can continue charging;

3. If the battery or equipment hardware fails, go to the after-sales service or specialty store for inspection and maintenance.

Do you use the charging head for this charging, the voltage is too low, change it to 2A and try it. You also check whether the data cable is good, and whether it is firmly connected to the head and hand, if there are no above problems, there is only a problem with the electric board.

1.The metal piece on the thread end that may be in contact is worn, which is the case with mine, and it will wear out after frequent plugging and unplugging, and then the contact will be bad.

2.The rechargeable battery function of the mobile phone is attenuated and cannot be stored.

It is recommended to replace the charging cable with a new one, or buy a spare power bank, or replace it with a new battery.

What's wrong? The main thing is to see how long your phone has been bought! If the mobile phone has been bought for less than a year, you can apply to ask them to check what the problem is, ask them to repair it or change the battery, if the mobile phone is less than a year, you should be able to replace the battery for free!

You always charge and play games, the battery is not good, everything has a life, the battery calls you to do a short life,

It's a problem with the charger! Change to a charging power source of more than 2A!

It may be a problem with the mobile phone, or it may be a problem with the charging plug, or the plug is burned when charging, and the wire inside is necrotic, so it can't be charged.

It's just that it will fall off while charging, but it will fall very slowly, and where will the screen be adjusted?

You just charge a lot of electricity, and the charging speed is slow.

After your own routine checkup, if you can't do it, go to the place where your phone is repaired.

The battery doesn't work, try changing the battery.

The charging hole is broken, let's replace the charging hole.

Generally, it only takes 2-5 hours to charge the new mobile phone line. Charging for 12 hours is a serious error.

The so-called first few charges of 12-24 hours is seriously wrong.

This theory is for the ancient nickel-metal hydride battery. Generally, mobile phones before 2002 mainly used this kind of battery, and now mobile phone batteries are all lithium-ion batteries or even lithium-polymer batteries.

NiMH batteries have a memory effect, and over time, there will be"Cell crystallization"phenomenon, which requires a long time of charging during the first few uses, and it is best to recharge after using the first few uses. As far as the industry is concerned, it is called full and full of release.

For lithium-ion batteries, this characteristic does not exist. So as long as it is full, it can be removed.

If it is charged for a long time, it will have a great impact on the life of the battery, in addition, when the mobile phone alarm is insufficient, it should be removed and charged immediately, and do not force it to be used until the mobile phone automatically shuts down, this practice will also accelerate the death of the battery!

This usage is called overcharge and overdischarge in the industry.

For today's mobile phones, there are two main ways: wire charging (direct charging) charging and dock charging (board charging).

The line charge is mainly suitable for business trips, the battery output of the line charge is very strong, and the current mobile phone wire charge is basically completely full in 2-4 hours.

The output current of the seat charger is low, and trickle charging is the main one. Therefore, the charging time is relatively long, generally 5-8 hours, but low-current charging is good for the life of the battery. So wire charging is suitable for emergencies when you only have one battery or are on a business trip.

The dock charger is suitable for everyday use.

Of course, the quality of the charger is very important, and for inferior chargers, whether it is a wire charger or a seat charger, their negative impact on the battery is self-evident.

The landlord's mobile phone is fully charged in 2-4 hours, and it cannot be said that there is a problem with the mobile phone battery or there is no problem.

However, there are many high-quality imitations of mobile phone batteries nowadays. So pay attention to distinguish between the real and fake batteries.

See details.

Apply best.

Probably not, just pay attention, try to use the automatic shutdown and then charge it every time, don't charge it before you run out of power.

Now the battery is basically a lithium battery, the memory effect is relatively small, the first charge is generally about 14 hours, the first three times of electricity is best put clean, so that the battery activity is better.

You use it without being fully charged on the second charge, there should be some minor effects, but the problem is not big.

Charging with a data cable will give people a bad problem, charging when using the computer, or charging when the mobile phone is connected to the computer, so that the battery is charged repeatedly, if it is too frequent, it will indeed affect the life of the mobile phone battery. Instead, charging directly on the power strip has the advantage (albeit the inconvenience).

Although it can't be turned on, it will light up, if it will light up, it means that your battery power is not good, if you charge it and still do this, then it may be that your battery cannot be charged. I'm also a 5700 diamond plate and it feels good to use. The sound quality is exceptional, and the camera flash is good.

Don't worry is not a big deal.

You can go to a few more repair points, and then see that the problem they say is the same as no, if it is the same, it is a problem in that aspect, and you can also go to the after-sales office, but if you go to the after-sales office, it will be out of warranty.

Words, ** very high.

There is a problem with the interface of the mobile phone charging place, how to deal with it:

1.If the battery is removable, it can be charged with a combi.

2.If the battery can not be disassembled, it can only be sent for repair, if there is no warranty period, it will be sent directly to the after-sales service, and if the warranty period is over, you can directly find a mobile phone shop for repair.

3.If you have strong hands-on ability, you can charge the slot online and repair it yourself.
