What s going on with the iPhone suddenly not charging

First of all, it may be that there is a problem with the charger, check if the charger can be used normally. If there is no problem with the charger, it may be a problem with the connection to the phone, check the interface and the phone charging slot for dirt or damage. If these checks are fine, there may be a problem with the battery or the motherboard of the phone.

The mobile phone charger is not original, so change the original charger and try again, there should be no problem. Hope.

It may be that the phone suddenly crashed, turn off the phone again, and then turn it on again to see if it can solve such a problem, if not, you can only take it to repair.

The reasons why the iPhone suddenly can't be charged are as follows:

1.The original charger is broken. The charger includes a charging head and a data cable, and it may be that one of them is broken or both are broken;

2.No original charger or cord is used. Third-party uncertified cables cannot be charged, and miscellaneous power banks will also fail to charge.

3.There is a foreign object in the tail plug interface. In addition to the headphone jack (7 and above series do not), the charging interface is the largest place to accumulate dust and foreign bodies, in the past, the 4 4S interface was larger and there was a dust plug, and now the interface is smaller, almost no one deliberately buys a dust plug, once there is a foreign body, it will affect the contact of the "gold finger" pin, and the poor contact will not be charged or charged slowly.

4.Start-up with too low temperature and full discharge. If the temperature is too low, the battery will enter the low-temperature protection mechanism, and a certain temperature is required to start, so the charging needs to be charged for a while before it can be turned on. When the power is completely used up to the point of automatic shutdown, it will also appear, and it will take a while to charge before it can be turned on.

5.There is a leakage of electricity on the motherboard. The leakage of the motherboard is manifested as slow charging speed, electric shock during charging, and fast power loss in daily use.

6.There is a problem with the battery. This is more complicated, it may be a problem with the battery itself, or it may be a problem with the control of the system responsible for the battery.

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

Generally speaking, this situation is relatively rare, and you can check the battery health first through the methods we taught above. A normal iPhone battery health of more than 85% within one year and more than 75% within two years is normal. But if you use it for a year and it has dropped by 80%, there are only two possibilities, one is that you have bought a fake, and the other is that you have often committed the behavior mentioned in the previous section to damage the battery.

I've seen people who charge their batteries almost several times a day because of playing card games, but in less than half a year, the battery health of their mobile phones has dropped to 78%.

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.

This is easy to do, ask someone for an original iPhone charger and charging cable to try it.

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.

The gold finger of the charging port is oxidized or dirty Use the SIM card pin of the iPhone to scrape 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).
