What s going on with the sudden crash of the Apple phone and the can t be charged

Cause: The charger and plug-in cable are damaged or not plugged in properly;

A phone crash causes problems with the parts of the phone.

Solution: You can change a charger or connect it to the computer with iTunes installed.

Factory reset your phone after backing up your data;

Use an alcohol swab to wipe the data port, and then recharge it;

Go to a professional phone repair shop for repairs.

1. For non-original chargers, this situation will often occur, which is caused by the charger specifications are not up to standard, and a qualified charger can be replaced.

2. Check whether the data cable is normal. The data cable looks normal on the outside, but it may have broken on the inside. The way to check is to borrow someone else's data cable to see if it can be charged.

3. The display plug symbol is normally displayed when it is full. If it is fully charged or the battery is insufficient, it means that there is no problem with the tail plug of the phone.

4. Go to the after-sales service for free testing and maintenance.

First, the reason for the crash is that the machine cannot be turned on.

1.The mobile phone can't be turned on, it is divided into many kinds, if there is a crash failure.

2.Then there is no need to make a fuss, just contact Apple's after-sales staff to make an appointment for testing.

3.If you press and hold the power button and it doesn't turn on, remember not to try again, so as not to cause the phone system to malfunction.

2. Reasons for jailbreak.

1.Many users have reported that after the jailbreak of the mobile phone, the mobile phone begins to turn on.

2.If you find that your phone can't turn on after jailbreaking, or after upgrading the system, you just need to connect to iTunes and fix it.

3.Or you can use other mobile assistant software to fix it.

3. Hardware failure.

1.The Apple phone can't be turned on, check if there is a problem with the switch button of the phone, or if there is a hardware problem in the phone.

2.Contact after-sales service for consultation and maintenance (Room 4407-4408, Metropolitan Plaza, No. 183 Tianhe North Road, Tianhe District, Guangzhou (next to China Mayor's Building)).

1.First of all, the Apple phone system is malfunctioning, which will cause problems with the battery level display. The simplest solution to this problem is to directly turn off and restart the phone, which is equivalent to refreshing the data and showing that the normal battery level will return to normal.

2.Secondly, there is a problem with the charger. This malfunction is the main reason why the phone cannot be charged. So how to judge the quality of the charger.

3.The charger and the phone are in poor contact. This is also a common phenomenon where users use their mobile phones improperly, resulting in the charger not being plugged in properly. The solution is.

4.Problems with the battery of the iPhone. Generally speaking, there are very few problems with the phone battery. But once you run into a problem, it's a big problem.

There are 2 possibilities, one is that the charger is broken, and the other is that the phone is broken.

You can use the elimination method to detect, use the charger to charge another normal mobile phone, if it can't be charged, it is a broken phone.

Or find someone else's good charger and charge it, if it can't be charged, the phone is broken.

And so on.

This has to find the reason in all aspects, one is that there may be a power outage, the second is that the charger is broken, the third is that the charging cable is broken, the fourth is that the mobile phone is broken, the fifth is not broken, the plug is not plugged in well, and the sixth is that you are teasing me.

The phone can't be charged, it may be because the battery is broken, or it may be because of the contact socket, this side of the contact is poor, there is no way to charge it, you first rule out these two possibilities, see if you can replace the contact fork first? If not, the battery is broken.

What's going on with the iPhone not charging.

Summary. Hello, glad to answer for you. Dear, the reason why the Apple mobile phone crashes and can't be charged is ...If the charger is broken, repair or replace it with a new one.

The iPhone crashes and can't be charged.

Hello, glad to answer for you. Dear, the reason why the Apple mobile phone crashes and can't be charged is ...If the charger is broken, repair or replace it with a new one. 2.The charging cable is broken, replace it with a new original cable.

3.If the mains power is out of power, wait for the mains power to be normal before charging. 4.If the charging port of the mobile phone is broken, repair or replace the charging port.

5. The power management circuit of the mobile phone is faulty, and the mobile phone is repaired. 6. The battery is broken and cannot be charged, replace the battery with a new one.

Hope the above helps

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

Summary. If the temperature is too low, it will also cause the iPhone to fail to charge.

If the temperature is too low, it will also cause the iPhone to fail to charge.

Because Apple's built-in electric wheel Huiyuan uses a lithium battery, and the iPhone's lithium battery is set up with self-protection, which is the so-called low temperature protectionIt means that under the condition that the temperature is too low, the lithium metal in the electric wax pool will be deposited, and no longer have a chemical reaction with the substance, resulting in a short circuit inside the batteryTherefore, in the cold winter and overly cold environment, users' iPhones will be charged slowly and cannot be charged.

Therefore, as long as the temperature increases, the mobile phone can naturally be charged, and the temperature attitude and charging efficiency will be very slow.

Also, if the battery can't be charged and the motherboard is damaged, you can replace the power supply IC.
