What is the reason why the iPhone can t be charged

The iPhone can't be charged may be:

The charger is too small to charge very slowly, try a good charger or computer interface;

If the data cable becomes worse or damaged, replace the data cable with better quality;

The data cable is in poor contact with the mobile phone or computer and the charging head, resulting in the charging current being too small, and it seems that it cannot be charged.

Problems of the battery itself, such as: the battery is close to aging, the battery self-discharge rate is high, etc., replace the battery;

If the internal control board of the mobile phone is broken, resulting in the charging current being too small or even none, replace the tail plate;

The charging socket at the tail of the mobile phone is in poor contact or bad, resulting in the inability to charge, the solution, replace the tail plate;

If the phone is in a cold environment, the charging will be slow, so you can put the phone back to a place with the right temperature to charge.

After so many years of experience using Apple:

1: The biggest problem is the power cord, because many domestic wires are configured in other factories, and the market is generally not a genuine line, so it is likely to be a problem with the wire, try to change the wire, 2: charging head, but the possibility of charging head is not large, try another one, 3:

The charging socket, whether there is a foreign object, blocked, 4: You should go to the warranty shop to see if the battery has been strained, if there is a problem with the battery, it should be replaced in time.

5: System problems, there may be system problems, go to the after-sales update system to try.

One reason is that it's too cold.

What should I do if my iPhone can't be charged?

Reasons and solutions for Apple mobile phone not charging.

1. The battery is excessively worn out and has been completely damaged.

This is relatively rare, and you can start by checking the battery health. A normal iPhone battery health of more than 85% within one year and more than 75% within two years is normal.

2. The battery management IC is damaged.

In this case, most of the reasons are that the motherboard components are desoldered due to the mobile phone falling to the ground, and the probability is very small. If the battery can't be charged and the motherboard is damaged, the store will charge you more than 500 so-called motherboard replacement fees, but in fact, you only need to replace the power supply IC for more than 100.

3. Non-original charger, the charging cable is damaged.

Ask for an original iPhone charger and charging cable and try it out.

4. Mobile phone system failure.

Press the power button + home button at the same time until the Apple logo appears, force restart the iPhone, it should be solved.

5. The gold finger of the charging port is oxidized or dirty.

Use the SIM card pin that comes with the iPhone to scratch the gold finger part of the charging port on the iPhone, and try to scrape off some oxides on it (generally this problem is definitely an old iPhone that has been used for more than 1-2 years).

iPhone Charging Notes:

1. The first time the iPhone is charged, it does not have to be charged for 12 hours, it can be fully charged, but remember that it is best to charge it when the screen prompts 10% for the first time, and do not run out of power.

2. After that, it can be charged at any power, and it is not necessary to wait until the power prompt is too low.

3. It is best to have a complete charging and discharging process once a week. If it is not possible to do it weekly, then at least ensure that the iPhone goes through at least one charging cycle every month , which is done in order to expand the capacity of the battery.

In the process of using the mobile phone, the mobile phone may have large and small problems due to the influence of the system, such as in the normal use process, there may be no sound all of a sudden, which affects the user experience.

Enter the main interface of your phone and select "Settings".

Enter the settings interface and select "Sound & Vibration".

Go to the sound vibration setting interface and make sure that "Mute" is turned on, if so, you need to turn it off.

In addition, when mute is turned on, the volume can also be set unilaterally to ensure that the volume is not zero.

Go to your personal interface and select "Settings".

Go to the settings interface and select "New Message Alert".

In the new message alert, find the "Sound" option to see if this feature is turned off, if it is turned off, there will be no sound alert. Mobile phones in all aspects of daily life, so it is very common for mobile phones to run out of power, sometimes when charging mobile phones, what should I do if I find that my mobile phone cannot be charged?

First, the battery is damaged due to the long service life of the mobile phone, and the solution is to replace the battery.

Second, the charger is damaged, and replacing the charger can solve this problem.

Third, it may be that the charging cable and the mobile phone are in poor contact, repeatedly connect the charging cable and the mobile phone to see if this problem can be solved, if it can't be solved, you can use a cotton swab to wipe the mobile phone charger port. Apple: These are all relatively common failures. It's just that all of a sudden the screen fails and you can't click on the screen.

This is generally how this is done.

1. I have fallen, or I have fallen not long ago, the screen touch screen has been loosened, and after a period of time, the wiring will fall off directly.

Second, if it has been flooded, it can be used again when it is dry, as if it is fine. In fact, the motherboard must be cleaned, otherwise the circuit will rust and there will be problems after a period of time.

3. High imitation charger and charging cable. Many people give off the bag when they buy it, and when they get it back, it is a high imitation, and after using it for a while, it hurts the power supply. Directly scrap the phone, especially the Hong Kong version of the mobile phone.

Fourth, charging while playing with your phone will also hurt your phone. Sometimes the current is too high and burns the inner screen.

Is there any way to fix this, check it, if the line is loose, change the line. If the inner screen is broken, directly replace the screen assembly.

If you change the screen, it is not good, it is the touch screen IC problem of the motherboard, the so-called touch screen IC is a chip that controls the touch screen, which can be replaced, but the process requirements are very high, this is a chip-level maintenance, and the general small shop will not. Only contact the after-sales center for repairs.

Apple's iPhone phone can't be charged when it is charged to 80%, and most of it is because overheating limits charging. 16-22° is the best temperature for Apple batteries, but we basically exceed this value in daily use. Under normal circumstances, touching the back cover has a certain sense of temperature and the battery is already overheated.

At this time, you can place the overheated phone on the tile or glass, and it can quickly cool down within 10 seconds, and restart it to recharge it after cooling down. If you are sure that the phone is not hot, the temperature is normal, but it still does not charge at 80% of the time, this usually happens on the system. The solution to this situation is to automatically turn off the phone before going to bed at night, and then charge the device.

1. The bottom interface of the mobile phone is blocked by foreign objects. The charging interface located at the bottom of the mobile phone is easy to enter the dust, which will cause poor contact between the interface and the power cord plug, so when the mobile phone cannot be charged, please check whether the interface at the bottom of the mobile phone is blocked by foreign objects.

2. The battery is excessively worn or completely damaged, this situation is relatively rare, you can check the health status of the battery first.

3. You can try to turn off the phone and turn it on again, sometimes it may be due to the system, resulting in the phone not charging.

4. In addition, there is the problem of temperature, due to the physical characteristics of the battery, it is particularly sensitive to temperature, too high will cause problems, too low will lead to uncharged. You can put your phone under the covers or in an air-conditioned room and charge it at a normal temperature.
