iPhone turns off when disconnected from computer. iPhone turns off? Trying to solve the problem on our own

If your iPhone restarts on its own, don't rush to give it to a service center right away. Guided by simple instructions, you can try to restore an iPhone of any model on your own, even without special skills.


To eliminate the breakdown, first of all, it is necessary 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 a faulty battery. But there are other reasons that affect the operation of the iPhone.

Causes of equipment failure

Your device may turn off and on every three minutes as a result of a battery failure. The power supply fails in the following situations:

  • iPhone connected to iPad charger
  • frequent voltage drops in the mains during recharging
  • iPhone was charging in the car

In each of these cases, the operation of the battery is affected by an unstable current level, which leads to battery failure. 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, as a result of which the battery lost contact with the device or was deformed)
  • software failure (applications are not tested for compatibility with the phone)
  • failure of parts
  • moisture ingress (affects the hardware of the smartphone)
  • failure of the power amplifier (the current inside the device is not regulated)

Signs of a broken smartphone

The main symptom of a malfunction in your device is that the iPhone restarts by itself. Other factors that indicate a breakdown of the device:

  • phone turns off during a call
  • The device heats up while charging.
  • every three minutes an "apple" hangs
  • appeared blue screen
  • appliances can't turn on

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


How to repair the damage yourself

To troubleshoot an iPhone that keeps turning on or freezing, first turn on operating system updates. Install them - the latest version of the operating iPhone systems may contain a correction of errors of the previous one. Also, on an iPhone that constantly reboots or heats up, many applications may be 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 moment.

In most cases, a forced reboot helps. To enter recovery mode, hold the Power button and the 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 itself on after a few minutes. All information (contacts, music, videos, photos) will be erased from his memory. Update your smartphone.

If the device constantly restarts 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 work without the help of specialists.

If, when you turn on the iPhone, an apple hangs on the screen, after which a blue screen is constantly visible, the central processor has become unusable. The right decision would be to replace the part - only a master can professionally perform it.

If you are sure that the reason is unstable iPhone work is in the battery and needs to be replaced. If you have experience and knowledge in the field of electronics repair, you will be able to do this work yourself. You will need a set of professional tools and a new battery.

To replace the battery, do the following:

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

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

In the event that independent actions did not solve the problem (iPhone reboots by itself or cannot turn on by itself), contact specialists for help.

The benefit of qualified assistance

Specialists have the necessary professional tools and experience in repairing all models of Apple equipment. Masters quickly carry out detailed diagnostics and determine the cause of malfunctions.

Experienced specialists know what to do if the iPhone reboots by itself. Masters use high-precision equipment and original parts to restore the device to working order.

By entrusting the phone to qualified specialists, you will get a high-quality result - after replacing the battery, cables, power button and other parts, the equipment will work stably.

Let's consider a rare but very unpleasant situation when the iPhone reboots itself during standby or active mode. It doesn't matter the device model. At the very end of the article, we will tell you how to deal with the situation.

How to find out why the iPhone restarts itself

AT latest versions iOS operating system added the ability to register events. If translated into familiar terms, then all events in the system are recorded. If your device starts to become unstable, then you can use this log. Using it, it is quite easy to calculate the problem area if the reason for the shutdowns is a software failure.

The feature or application activation record will always be the last one before the crash record. If there is no failure record, then the cause of shutdowns lies in hardware failure and you need to contact the service center, because. without the intervention of repair engineers can not do.

  1. If the phone turns off by itself or during iPhone call reboots, there is a high chance that the battery is losing contact with the device. Simply put, the battery is moving away from the contacts. This is often due to the fact that with prolonged use of the device there is a slight play (gap between the connecting elements) of the battery cover.
    When talking or active use, the body shakes, which causes the contacts to separate. To test, take your phone and shake it vigorously a few times. If a trip occurs, the cause has been found.
  2. If this is not the root cause, then follow the statistics. Perhaps when you make a call, when you launch a certain function or application, or just when loading, the iPhone reboots, then a software failure is most likely.
    If there are failures in the structure of the operating system or the application has not been tested for full compatibility with the device, then upon activation, abrupt interruptions in operation in the form of a spontaneous shutdown or reboot are possible. To avoid (and solve) such problems, we recommend that you keep updating software products and use only certified applications.

As practice shows, if updating the firmware or resetting the settings to the factory settings in the iPhone did not help, then you can solve the problem with rebooting only with the help of qualified help from the masters service center.

And decided to connect it to your computer. And at the time of connection, you encounter such a problem: either a blue screen crashes (do not confuse with the Blue Screen of Death" (BSOD), with an error message like "*** STOP: 0x0000007e (0xC0000005, 0x00000000,0xF79E37c4, OxF79E34CO), or the computer just spontaneously starts rebooting.The error occurs as a result of driver incompatibility, or if they are damaged.

In particular, this problem has been observed in connecting an iPhone to a computer with a Logitech webcam installed. The conflict occurs because the webcam driver is incompatible with the iPhone driver (this is indicated by the STOP message: 0x0000007e). How is the problem solved? The problem is solved in two ways.

Method 1

You just need to update your webcam drivers. To do this, you must go to the Logitech website. Search for the necessary drivers by the name of your camera and simply download them. After being found correct driver, install it, restart your computer and try connecting your iPhone again. If suddenly the problem with an error and a reboot repeats again, then method number 2 will help you.

Method 2

Find and remove ALL webcam drivers. Here's how to do it:

  1. Right click on "My Computer". In the drop-down menu, select the line "Properties". AT open window"Properties" click on the tab "Equipment";
  2. We see the inscription "Device Manager" and click on it. Next, among the devices installed on the computer, we are looking for your webcam;
  3. hover over the webcam and click the RIGHT mouse button;
  4. in the menu that opens, select "Properties" and click on "Properties" with the LEFT mouse button;
  5. a menu will open in which you select the tab "Driver" and remove this driver. When asked to confirm the deletion, click "Yes";
  6. now reconnect your i-Phone to your computer. The problem shouldn't happen again.

And now how to solve the same problem, but on Windows Vista. So:

  1. Right-click on "My Computer" and select "Properties" in the pop-up window;
  2. click "Device Manager";
  3. next - open the branch with the computer name (displaying all devices);
  4. we are looking for your webcam, find it, click on it with the RIGHT mouse button and select the line "Properties";
  5. find the "Driver" tab and click "Delete";
  6. confirm the deletion (click "Yes") and connect your iPhone again: everything should work!

Apple products are very reliable in the workflow and are distinguished high quality during operation. But, the most frequent visits to service centers are when the iPhone turns off by itself, and also turns on.

There are times when the iPhone turns off and on with no sign that the battery is dead even during the conversation. Frequent turning off and on randomly may be caused by a software error, as well as a defect in the device. This might be the reason when iPhone 5s keeps restarting.

The reasons when the iPhone 5, iPhone 4s, iPhone 6s can spontaneously turn off and turn on may be in the following points:

  • The iPhone turns off when there is a problem with the battery, for example, if the device is accidentally dropped, the contact nodes or the battery itself may be damaged. In these cases, the iPhone itself can turn off and on at any time, and it can also happen when it is shaken. After removing the battery and putting it in place, the battery charge will differ from zero;
  • The machine may turn off if any third party application. When you run such a program, the iPhone may turn off. This happens due to possible inconsistencies in the content of applications. ios program, as a result, in the process of launching the application, the program will crash;
  • probable wear of the communication sensor, during long operation it may fail, due to which the signal will be received at an insignificant level. As a result, due to the constant search for high-quality signals, the load on this node increases, with a rapid discharge of the battery. With significant wear, due to the discharge of the battery, the device turns off;
  • termination of the device automatic mode(going to sleep).
  • Apps stop functioning and the iPhone may freeze or go into power saving mode. This process is very easy to check, for example, the functions of the device are disabled, while the device itself continues to work. In such cases, the functions can be enabled only if the screen is activated or the desired functions. If the timer is set incorrectly, the machine may turn itself off. To disable this function, you should go to the “timer” mode, and then to the settings, with the shutdown;
  • if the iPhone restarts itself, the reason for this may be software, for example, when installing a beta version ios systems, it can also cause the iPhone to turn off;
  • The iPhone itself turns on or off when the device is in the cold for a long time (in the cold). In this case, the iPhone itself may turn off;
  • possible problems with the hardware. In 90% of cases of these problems, it is the battery or the power controller. In this case, it is advisable to replace the battery or controller.

Troubleshooting steps

In cases where the iPhone 4s or iPhone 5s constantly reboots, you should reset the operating system, with a high-quality cleaning of the iPhone using the phone (the reset is in the main menu):

1 If the iPhone 4 turns off by itself, and also if the iPhone 5 reboots itself, you need to perform a hard reset, resetting the time indicators. To perform this operation, you must press the function - "home" and hold until a message appears about the process of loading the battery. 2 Connect the adapter to the iPhone. The device will turn off while charging the battery. If after some time the iPhone 4s, iPhone 6 or 5s itself turns on and off, you should replace it battery. This is especially effective if the iPhone 4s is rebooting. 3 The occurrence of software errors may cause the machine to reboot or hang on reboot. To prevent this factor, you should carry out the recovery process through itunes (flashing). 4 Use a more powerful iPad adapter (which is also recommended by the manufacturer if these problems occur). 5 Entering the device into DFU - mode, leaving the device on boot for a while. Since in this state the system is not loaded (the screen is off), which means that the energy goes to charge the battery. A very effective method, especially if the iPhone is hanging on an apple, is to connect the wire to the device for 3 seconds, while you should not wait for it to turn off, but immediately pull it out. The algorithm of the actions performed is as follows: connect for 3 seconds, then pull out for 3 seconds. Thus, the process of connecting (3 seconds) and disconnecting (3 seconds) is carried out within 3 minutes. After 3 minutes, the reboot issue will be resolved. At the same time, the iPhone will reboot every few minutes. This method is able to solve the problem associated with the arbitrary switching on and off of the device.

If all of the above steps did not help, you should contact a specialized service center for the repair of this equipment, where qualified specialists will help in solving problems related to the spontaneous turning on and off of the iPhone, as well as rebooting every few minutes.

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

Our site is not responsible for your actions. We recommend contacting professional help to the service center for the repair of iPhones and other mobile equipment.

Example. December 2, 2017 many owners iPhone started reboot itself. The reason for everything is a bug in iOS 11.1.2: if any notification came from any application, then the phone went into reboot. Apple promptly released update 11.2 which fixed the issue.

iPhone restarts itself due to a software error or glitch

Modern applications, especially from unofficial publishers, can cause devices to work incorrectly. It is not difficult to identify the "culprit" of the breakdown. To do this, view the event log on your smartphone.

Application crash reports are available in general settings (usage and diagnostic information). If the unstable operation compulsively manifests itself after installing a particular product, then the problem area has been calculated. Note that a crash record is always recorded after the activation of a certain function or installation of an application.

Periodic shell updates can also play a trick on the smartphone user. Incorrectly executed firmware - installing the current operating system into the device's memory - leads to spontaneous shutdown. It is recommended to make sure that the installation of the operating system is performed correctly, as well as to check its compliance technical capabilities specific model iPhone.

If software or itself operating system models are not the reason for the shutdown, which means that the breakdown lies in the hardware of the smartphone. In this case, it is necessary to contact the specialists of the service center to eliminate it.

Hardware failure - the reason for restarting iPhone

1. Often the battery is the “weak” link of the iPhone. The battery may simply lose contact, which is quite enough to disrupt stable operation. Please note that over time, any iPhone gives a "backlash" - a small gap between the fixing elements of the device cover.

2. The battery may simply be worn out and not withstand the load. Naturally, when the battery has lost its capacity, the smartphone will turn off. Remember that the life of a full battery charge is only 400 cycles. After developing such a limit, the capacity of such an important component will steadily fall. In addition, a voltage drop right during charging can cause damage to the battery contacts.

3. A malfunction of the smartphone board, which usually manifests itself after intense shaking or a strong blow. Such a “breakdown” in the electrical signal transmission circuit leads to the shutdown of the apparatus when its position changes abruptly. However, this problem often leads to breakage of other components of the iPhone.

4. Breakdowns of the smartphone processor lead to the impossibility of its full use. Often still at the launch stage. "Hangup" occurs at the stage of displaying the splash screen. Usually, malfunctions, as well as complete burnout of the central processor, are restored by replacing the component.
