The phone charging shows what is the reason for the mismatch

Poor charger contact, broken phone charging port, or socket problem.

How to solve the charging error of the mobile phone charging display:

Try replacing the charger, if it still doesn't work, it's not a problem with the charger.

Use the charger to charge other mobile phones, if it is easy to use, it may be a problem such as aging of the charging port, and you need to find after-sales maintenance. In the same way, you need to change the place to charge and check whether it is a problem with the outlet. When encountering faults that cannot be eliminated, non-experienced people, do not disassemble the machine by themselves (disassembly is risky), and can go to the nearest after-sales maintenance during the warranty period.

Precautions for mobile phone charging:

It is best to have a phone that has just been bought for more than 8 hours, and preferably no more than 12 hours.

Causes and solutions: 1. The voltage is not enough: It is recommended to change the socket, or adjust the brightness of the screen of the mobile phone to the darkest, turn on the airplane mode, and then plug in the stupid hidden charger again.

2. The charger or data cable is not original: After upgrading to ios7, even if the charger is original and the data cable is not original, it will cause a mismatch. Replace it with the original phone cable and the original charger and recharge.

3. Check whether the room temperature is too low: Apple has set up a low temperature protection for the iPhone battery, and sometimes the phone will not be able to charge if the temperature is too low, so as to prevent the deposition in the battery, resulting in a short circuit inside the battery. 4. The charging head has been aged for a long time or the interface is dirty

Change the charging head. Take a thin piece of metallographic sandpaper and cut it out to a suitable size, fold it in half a few times, and then gently polish it a few times in the data god backup line interface.

Generally speaking, charging with a charger that does not match the mobile phone will cause certain quality damage to the battery, thereby reducing the use time and quality of the battery, so it is not recommended.

How the charger works:

1. The charger is actually composed of a stable power supply (mainly a stabilized power supply, providing stable working voltage and sufficient current) plus necessary control circuits such as constant current, voltage limiting, time limiting, and overshoot.

2. The output parameters marked on the original charger (finger line charge): for example, the output output refers to the relevant parameters of the internal regulated power supply. For example, the output can be used for devices, and it can be used for 6V devices.

First of all, the switching power supply also has a transformer, whether it is a mobile phone charger or a switching power supply for a computer, this has been indicated, so why can this transformer be so small compared with the traditional transformer?

The transformer room transmits energy through electromagnetic conversion, and in the case of a certain current, there are two main factors for the current to convert to electromagnetic energy, the number of turns of the consciousness coil, but the frequency of alternating current, the traditional transformer due to the fixed frequency of the mains 50hz, in order to transmit greater power, can only change the number of turns, so the larger the power, the larger the transformer.

By increasing the frequency of alternating current on the transformer, the switching power supply can keep the transformer small in size while meeting the power requirements, which is very much in line with the needs of modern electronic equipment.

Therefore, there is still a transformer in the current mobile phone charger, the difference is a high-frequency transformer, and the same is that the output terminal and 220V electricity are still isolated by electromagnetism.

Those who say that switching mobile phone chargers do not have a direct electrical connection to the transformer room are purely misleading.

If it is low, there is no harm except for slow charging and insufficient charging; However, if it is too high, the damage will increase as the current and voltage increases, and it may occur from damaging the battery to burning the circuit.

Does the question have an impact on the open data?

Question: What is the reason why the data is turned on after a period of time and it is closed?

1. When using the 4G network, receive SMS or call**, the mobile phone will switch to the network, temporarily interrupt the data network, and will automatically connect after the SMS is received or **hang up;

2. When the network signal is unstable at the current location, it will also cause the data network to be automatically disconnected;

3. When the power-saving software or settings are used on the mobile phone, the data network will be interrupted;

4. The SIM card of the mobile phone is abnormal.

In this case, the above reasons can be ruled out first.

I didn't ask any questions, what the hell was that.

If the power supply current of the adapter is small, it will be harmful to the adapter, and it will not cause harm to the mobile phone.

The voltage or power does not match, it is harmful to the mobile phone, and it is best to use the original machine.

It will not affect your phone, at most your charger is not properly matched with his phone, causing damage to his phone.

How to take care of your phone charger:

1. Discharge static electricity during cleaning. Clean the charger and charging port regularly. To clean up, use a damp cloth, or an antistatic cloth. Never use a dry cloth (it will have an electrostatic charge)!

2. Waterproof and moisture-proof. As an electronic product, accidentally entering water or being exposed to humid air when not used for a long time will cause varying degrees of corrosion or oxidation to the electronic components inside. So don't put it in the bathroom or other places.

3. Drop-proof and shock-proof. A mobile phone charger is actually a fragile component, and the internal components cannot withstand a beating. In particular, it is necessary to prevent accidental landing during use. Do not throw, knock or shake the charger. Treating the charger roughly will destroy the internal circuit board.

4. Anti-cold and heat-proof. Do not leave the charger in a place where the temperature is too high. High temperatures can shorten the life of electronic devices, destroy chargers, and deform or melt some plastic parts.

Also do not store the charger in a place that is too cold. When the charger is working in a super-cold environment, when the internal temperature rises, moisture will form inside the charger and destroy the circuit board.

5. Anti-strong chemicals. Do not clean the charger with harsh chemicals, detergents, or strong detergents. To remove the appearance stain of the charger, you can use cotton dipped in a small amount of anhydrous alcohol. Scrub.

It indicates that the user is using a non-original charger and cannot pass the system authentication before the message indicates that this configuration is not supported.

Not using the original charger will not only prompt that this configuration is not supported, but will also cause the following consequences:

1. Shorten the life of the mobile phone;

2. Damage the mobile phone;

3. The mobile phone heats up when charging and burns the mobile phone;

4. There will be leakage when charging;

5. The screen flashes when charging.

If you use a charger that is not the original, it will not be supported.

It may be that there is a problem with the charger, try changing the charger.
