The iPhone turns on and off while charging. Why does my iPhone restart when charging?

In this article, we will figure out why the iPhone X/8/7/6/5 reboots itself, we will find the reasons and try to eliminate them.

Our site is not responsible for your actions. We recommend that you contact professional help V service center for repairing iPhones and others mobile technology.

Example. December 2, 2017 for many owners iPhone started reboot itself. The reason for this was a bug in iOS 11.1.2: if any notification came from any application, the phone would reboot. Apple quickly released update 11.2, which fixed the problem.

iPhone reboots itself due to a software error or glitch

Modern Applications, especially from unofficial publishers, may cause incorrect operation of devices. It is not difficult to identify the “culprit” of the breakdown. To do this, view the event log on your smartphone.

Reports on incorrect operation applications available in general settings(information on use and diagnosis). If unstable operation intrusively appears after installing a specific product, then the problem area has been calculated. Note that the entry about emergency shutdown always after committing activation specific function or installing an application.

Periodic shell updates can also play a cruel joke on a smartphone user. Incorrectly executed firmware - installation of the current one in the device memory operating system- leads to spontaneous shutdown. It is recommended to ensure that the installation of the operating system is carried out correctly, and also check its compliance technical capabilities specific model iPhone.

If the software or the operating system of the model itself are not the reason for the shutdown, then the failure lies in the hardware of the smartphone. In this case, you need to contact the service center specialists to eliminate it.

Hardware failure - the reason for rebooting the iPhone

1. The battery is often the “weak” link of the iPhone. The battery may simply lose contact, which is quite enough to cause a violation stable operation. Please note that over time, any iPhone develops “play” - a small gap between the fixing elements of the device’s lid.

2. The battery may simply be worn out and cannot withstand the load. Naturally, if the battery loses capacity, the smartphone will turn off. Remember that the battery life of a full charge is only 400 cycles. After reaching such a limit, the capacity of such an important component will steadily decrease. In addition, a voltage drop during charging can cause damage to the battery contacts.

3. A malfunction of the smartphone board, which usually appears after intense shaking or a strong impact. A similar “breakdown” in the transmission circuit electrical signal leads to the device turning off when its position changes abruptly. Moreover, this problem often leads to breakdown of other iPhone components.

4. Failure of the smartphone processor makes it impossible to full use. Often still at the launch stage. Freezing occurs at the stage of displaying the splash screen. Typically, malfunctions, as well as complete burnout of the central processor, are restored by replacing the component.

In this article we will look at the main reasons why the iPhone turns off by itself, what led to this and how to solve the problem now. The material is relevant for everyone iPhone models X/8/7/6/5/4 and their modifications S and Plus.

iPhone is an accessory that provides limitless communication opportunities, while at the same time being a stylish gadget that emphasizes the user’s excellent taste. Every day people spend a lot of time texting each other, calling each other, surfing the Internet.

The smartphone has taken over a person's life great place. It’s all the more offensive when the device malfunctions during operation. Serious malfunction- iPhone turns off spontaneously. During important conversation or correspondence, the device may simply go out, causing a lot negative emotions. There are several reasons and ways to fix the problem. Let's look at each separately.

Battery problems

This is the most popular, common reason. A malfunction can occur in several cases.

The phone fell, which caused the battery contacts to become disconnected. But this phenomenon is not permanent. The fact is that the contacts did not break off, but simply became disconnected and now spontaneously change position. The smartphone may work normally, but as soon as the owner shakes it (by taking it out of his pocket or in some other way), then the contacts iPhone battery will disconnect from the power board, which will turn off the device. The charge level does not matter.
Non-original battery. This happens when, when replacing a “native” battery, cheaper Chinese analogues are installed. The capacity of these batteries may a priori be insufficient. But the phone will still work. Only during operations that require large amounts of energy (internet surfing via turned on Wi-Fi and simultaneous conversation on a cellular line), a power surge will occur and the battery capacity will drop to zero - the phone will turn off.
The battery is faulty. Each battery has its own recharge limit, after which it begins to deteriorate. Another situation where the iPhone is exposed to temperature changes is for a long time arrives in an environment that is either too warm or too cold.

How to fix

If the contacts of the cable break, you should contact the service center - it’s good if the warranty is valid iPhone yet works. An unqualified solution to the problem on your own is fraught with more disastrous consequences.

When a non-original battery is used, the way out of the situation is simple - replace it with a certified one. Just first you need to find out the power that the phone consumes, and then purchase the appropriate battery.

When the battery is faulty or has expired, we do the same the previous method- buy a suitable original battery. There's one here important point. Replacing the battery on an iPhone is not an easy process. You can find a lot of instructions on this topic on the Internet. But in reality, sometimes everything is different. In addition to skills (or at least experience), the user will need a special tool. Its cost varies. It will be easier to immediately take your iPhone to specialists who will promptly change the battery for a modest fee.

Problems with the power controller

Apple smartphones are devices where everything is thought out. There is a special chip that controls the voltage supplied during charging. The phone battery is powered from the mains AC, through a special adapter. Before entering the battery, the voltage passes through the power controller (the same chip). It acts as a barrier that prevents damage to the battery. When the voltage meets the battery requirements, then charging in progress, and when it is higher, the chip is triggered, preventing the impulse from reaching the battery.

If iPhone turns off on its own, then this may indicate a breakdown of the power controller. In this case, the phone's operating system tries to “protect” the battery from voltage surges.

Repair method

Only service center specialists can correct the situation. The failed power controller will need to be replaced. This process involves working in the system iPhone board, where unprofessional actions will lead to complete failure of the device.

Operating system errors

iPhone, like any modern device, has many functions. One of them is direct interaction with the components of the phone. This is done by reading information from certain sensors. But this function does not always play into the hands of the owner. Some software errors cause the iPhone to turn off by itself when fully charged.

How to fix the situation

The first, simplest option is full reboot devices. To do this, you will need to simultaneously hold down the power and home buttons. They should be held in this position for at least 15 seconds. If the reboot is successful, the manufacturer's logo will appear on the display.

It happens that the charging indicator is faulty. It has already been noted that the system works with iron in complete symbiosis. There is an error in which, despite the fact that the battery is charged, the corresponding indicator shows “0”. The system immediately reacts to this by turning off the phone. It's easy to fix the situation:

We completely discharge the iPhone.
Leave it in this state for 2-3 hours.
Then connect the charger.
We charge to 100 percent.

Another way to deal with errors is to restore the operating system. The process is carried out through iTunes programs(any user of Apple devices has it). After which we get a completely “clean” gadget with the newest (available) operating system. Before recovery, to avoid loss important information should be done backup copy data in the same iTunes or save them on the iCloud cloud server.

Conflicting Applications

There are applications that, when activated, conflict with the operating system. This is caused by program incompatibility and IOS version, the result of which is to turn off the device. There are two ways out of the situation.

Update your operating system if available.
Remove the conflicting application.

Some programs require additional hard drive space. An example would be a photo editor that processes an image, saving the result separately without touching the original. When the memory is insufficient, the system may react by turning off the phone. Exit: Free up space on your hard drive or don't use the application.

iPhone may shut down due to CPU overload caused by a large number simultaneously used programs. The component overheats and, to protect it, the operating system issues a shutdown command.

Water ingress

Water, along with dust - main enemy digital technology. If moisture gets inside the gadget, the device stops working correctly. This may manifest itself in the fact that iPhone turns off by itself and turns on only with charging. In order not to completely ruin the device, you should contact a service center, where the phone’s hardware will be dried. It is not recommended to get rid of moisture inside your smartphone on your own.

It happens that when connecting iPhone 5/6s plus via USB to desktop computer, the PC does not see the Apple device at all, the communication signal is faulty, or nothing happens at all. Why do iPhone synchronization problems happen, and who is to blame for this?

The reason for desynchronization may be:

iPhone, in this case the reason for not connecting is outdated iTunes versions, failure of the connector slot, its clogging, or, which is extremely rare, a hardware failure of the gadget.
Computer, if the iPhone does not want to connect to the PC, it means this version the operating system is not suitable for these purposes, or is missing necessary drivers, or the Apple device support version is out of date. The reason for not connecting may be enabled antiviruses, security monitoring programs, existing viruses, or simply a glitch in the system.
The connector between the PC and the iPhone, in this case the computer does not see the iPhone at all, or the connection is intermittent.

If there is a problem with synchronization Apple devices and the laptop/PC is not resolved by rebooting both gadgets and reconnecting, then we try to identify the cause further.

iPhone 5/6s plus cannot connect to PC, what should I do to synchronize?

Try different USB ports, maybe the reason is just a broken USB slot.
Temporarily disable antivirus and security systems on your laptop/desktop computer.
Make sure that the reason for the iPhone not connecting to the PC is not the connector cable. By the way, it is better to use exclusively the original cord from Apple; in Chinese analogues, the transfer speed is slightly lower than in the latest versions of Apple connectors, this is another reason why the iPhone may not work correctly with a PC, and also will not have time to update iTunes via the computer.
It is worth updating iTunes to the latest version from the official Apple website.
If this helps, and the computer begins to see the gadget or the iPhone is at least recharged from the computer, then iPhone screen 5/6s plus should display “Trust this computer?”, select trust, after which synchronization should occur.
If the iPhone still cannot connect to the computer: the cable is original, charging is in progress, and the trust request message is successfully confirmed, then the problem is clearly in the PC: you will have to reinstall the PC Operating System.

Also, it’s worth trying synchronization with other devices from friends or relatives; sometimes it’s easier to go to a neighbor’s house and download photos/videos from your iPhone, download music and movies, than spend half a day searching for an answer to the question: why won’t your iPhone connect to your laptop? And you can always go to our iFix SC, including with both gadgets, we will quickly solve the problem without iPhone connections to the computer.

iPhone won't connect to computer. Reason - PC

Yes, in most cases this is what causes connection problems. To eliminate them, we perform the following steps:

First of all, reboot both devices. So to speak, for prevention.
Let's try various USB ports and check, for example with a flash drive, their functionality. After all, one of them may burn out or simply not work.
We do not use adapters, splitters, extension cords or other devices for USB ports. We plug the cable directly into the system unit.
We update iTunes. The ideal option would be complete removal, and subsequent installation of the latest version from the site Apple.
Disable third-party software (antiviruses, firewalls). Don't forget to turn them on after checking!
The most radical step is to reinstall the operating system; it will most likely help, but it will take time...

Unable to connect iPhone to computer

If the iPhone cannot connect to another computer, then the problem is clearly in the device... No matter how reliable and stable Apple products are, they can also be the cause of connection problems. Although most often, the owners of these devices are to blame, having brought them to such a state that it becomes surprising how they can still turn on, let alone synchronize. I got distracted for some reason :)

Returning to the topic, let's try the following steps:

After connecting, unlock your phone, it is quite possible that you will see a pop-up window with the question: “Trust this computer?” Without an affirmative answer, no synchronization will occur, only charging.
Change cable. Even if there is no visible damage, the wire may be faulty. Or it is quite possible that it is not original - but in this case, it is possible to make the device work with an “unsupported” accessory.
Reset device content and settings. If you decide to take such a desperate step, remember backup information (if iCloud help or iTunes), otherwise you will lose all your data forever.
Jailbreak, or more precisely the so-called tweaks installed with its help, can also contribute to synchronization problems.
Update software. It's always useful!
Clean the connector on the phone (it may have become oxidized or dirty). Important! Clean very carefully, ideally leave it to a professional. If you decide to do this yourself, look for information on the Internet, otherwise you may make the situation worse.
The last point we have is the saddest one - the connector for charging and synchronization is broken or out of order. There is only one way - to the service center! If possible, contact only official workshops listed on the company’s website.

The computer does not see the iPhone

By the way, there is another win-win option - contact the service Apple support. And torment them with the question: “Why doesn’t my iPhone connect to the computer using USB?” To be honest, I haven’t tried, but I don’t think I’ll hear anything new from them, and the conversation will take a lot of time.

Contact support

As you can see, in most cases you can get by with “ little blood» and troubleshoot problems at home. If you have tried all the points given in the article, but the situation has not changed for the better - the iPhone still does not connect to the computer, then describe the situation in the comments - we will figure it out together!

Hello everyone! Many iPhone owners and iPad new problem - trouble came, as they say, from where it was not expected. After all, just recently their device was perfectly synchronized with the computer, but now not only does the connection not occur, but also when disconnected from USB port the device simply reboots. The question arises - why does this happen? Let's figure it out together, let's go!

The first and most important point. If problems connecting to a computer are not accompanied by turning the device off and on, then the solution will be slightly different - with this scourge. We study, apply, enjoy the result. Nothing complicated!

And we will return to today’s task, the essence of which boils down to the following:

Previously, an iPhone or iPad was connected to a computer and everything worked.
IN certain moment, iTunes stopped seeing the device.
As soon as we disconnect from the PC (pull out the cable), an independent reboot occurs.

What I would like to note right away is that with a high degree of probability, your iPhone or iPad is not to blame for the current situation. In any case, there is no need to immediately run and change the charge controller, the lower cable, the connection connector, motherboard, and you don’t even have to try a different cable.

Why? Everything is checked for personal experience- I have a similar situation with my home computer (if you disconnect the wire, the iPhone goes into reboot). But on the laptop everything is fine. In this case it is used original cable"out of the box".

So what's the catch? In fact, the reboot occurs due to errors in synchronizing the device with the computer, and, with a high degree of probability, these errors have one reason - the software installed on your PC. Here's what I did and how I ended up overcoming this problem:

In general, I updated everything I needed, deleted everything I didn’t need :) And just to be sure, I also rolled it back to normal and stable iOS.

What can be concluded? The whole thing (at least for me) was 100% in conflict software- which, of course, is strange. Because a simple lack of connection is one thing, and a reboot is another. After all, if I didn’t have another computer (on which everything is “OK”), I would start changing wires, cleaning connectors, maybe even contact a service center - and that’s all money and time.

But all's well that ends well. I hope you will have a similar result and, after these simple manipulations, spontaneous shutdowns will disappear.

If your iPhone reboots on its own, do not rush to immediately take it to a service center. Following simple instructions, iPhone any You can try to restore the models yourself, even without special skills.

To fix the problem, you first need to find out why the device can turn on and off on its own at any time. In most cases, the iPhone periodically reboots due to faulty battery. But there are other reasons that affect the operation of the iPhone.

Causes of equipment malfunction

Your device may turn off and turn on again every three minutes as a result of a battery problem. The operation of the power supply is disrupted in the following situations:

iPhone connected to iPad charger
Frequent voltage drops in the electrical network when recharging
iPhone charging in car

In each of these cases, battery performance is affected by unstable current levels, resulting in battery failure. IN in this case the battery will need to be replaced. Often the phone cannot turn on and work correctly for the following reasons:

mechanical damage (the device was hit or dropped, causing the battery to lose contact with the device or become deformed)
software glitch (applications are not tested for compatibility with the phone)
failure of parts
moisture ingress (affects the smartphone hardware)
failure of the power amplifier (the current inside the device is not regulated)

Signs of a broken smartphone

The main sign that your device is malfunctioning is that the iPhone reboots on its own. Other factors indicating a device failure:

phone turns off during a call
The device gets warm while charging
an apple hangs every three minutes
appeared blue screen
equipment cannot turn on

Symptoms depend on the factors causing the failure. To identify the exact cause of the malfunction, it is necessary to carry out diagnostics.

How to fix the problem yourself

To troubleshoot an iPhone that keeps turning on or freezing, first turn on operating system updates. Install them - latest version operating room iPhone systems may contain corrections of previous errors. Also, an iPhone that is constantly rebooting or heating up may have many applications installed that require updates to be enabled.

Clear your phone memory, free up a few gigabytes. This will help increase the performance of the device, which tends to constantly turn on and freeze at any time.

In most cases it helps forced reboot. To enter recovery mode, hold the Power button and Home button for 20 seconds until the apple logo appears.

If these steps do not help, copy the files and reset the operating system:

go to Settings
select "Basic"
go to the "Reset" tab
select "Erase all content and settings"

The phone will shut down and turn on on its own after a few minutes. All information (contacts, music, videos, photos) will be erased from his memory. Update your smartphone.

If the device constantly reboots due to exposure to moisture or other mechanical damage, the device will require detailed diagnostics and replacement of parts. In this case, it will not be possible to do without the help of specialists.

If, when you turn on your iPhone, there is an apple hanging on the screen, after which a blue screen is constantly visible, it has become unusable CPU. The right decision There will be a replacement of the part - only a master can do it professionally.

If you are sure that the reason unstable work The iPhone is hidden in the battery, you need to change it. If you have experience and knowledge in the field of electronics repair, you can do this work yourself. You will need a set of professional tools and a new battery.

To replace the battery, you need to do the following:

turn off the phone
unscrew the screws
remove the phone cover
disconnect the battery, remove it
clean your phone from dust and debris
install a new part
collect equipment

If, after replacing the battery, some functions in the phone fail (the speaker, the Home button, etc. do not work), you need to check the correct connection of the battery to the device and the integrity of the cables.

If independent actions do not solve the problem (the iPhone reboots on its own or cannot turn on on its own), contact a specialist for help.
