iPhone shuts down for no reason and does not turn on
What to do if the iPhone does not turn on
If your iPhone suddenly stops turning on and does not respond to button presses, do not panic and run straight to the service center. Even Apple devices are not perfect and occasionally can fail, both for technical and software reasons. And it’s not always necessary to intervene in order to bring your device back to life. Your iPhone, just like any other gadget, can be reset on its own, there are many ways to do this.
There are many reasons why your iPhone does not turn on, and there is simply no single method of correcting this error. The problem may be software or technical, which is much worse.
Many owners of Apple phones, when they see that the device does not want to turn on, immediately rush to the service center. But after all the panic can be unjustified! Often a lot of causes of failure can be corrected with your own hands.
Often the phone refuses to turn on because of an elementary “deep” battery discharge. Its charge is simply not enough even to display the brand logo. The device should simply warm up and then allow it to charge at least 15-20 minutes.
If the smartphone is frozen and does not want to respond to the power button, it must be reset forcibly. It is better to do this with the power adapter turned on, because many devices forcing a reset requires at least 40% of the battery power, which at the moment may simply not exist.
But, unfortunately, there are situations in which to turn on the phone and have to go to the service. But about all this below.
Before breaking down all the existing ways in which you can help your iPhone to turn on, it is necessary to consider the main reasons why it refuses to do so.
How to Fix My iPhone won’t Turn On (iPhone dead)
What to do
The first thing is to charge the phone and leave it for 30. 60 minutes (even if it does not give any signs). Afterwards, try to turn it on in the usual way. If there is no reaction and even the backlight does not light up, then there is clearly a problem with the power. That is, the hardware. Then you should go to the service center. You can replace the battery yourself, but it’s not certain that the problem is with it. It is possible that the power controller failed and the phone simply does not recognize the battery (the controller on the battery transmits information about the current charge, the controller on the motherboard reads it and then starts the initialization process).
If the iPhone turns on and off right away while charging, that is, during the boot process (the display shows the Apple logo. The apple). It is very likely a software failure. To fix it, you need to do a complete reset of the device as follows:
- Update your PC to the latest version of iTunes (only MacOS and Windows will work, no iTunes for Linux distributions);
- Connect your smartphone to your computer with a USB cable (preferably to the USB 2 port).0 placed on the back of the system unit);
- If the phone is recognized in iTunes (the iPhone display will show the image of USB-connection), you must select “Repair iPhone” in the application and following the prompts on the screen. Reset the phone, the firmware itself will be downloaded automatically;
- If after connecting iPhone to PC nothing happens. You must press the Home and Power keys simultaneously on the smartphone and hold them for 10 seconds, then release Power, but keep the Home key pressed, waiting for the drivers installation, then select “Repair iPhone” in iTunes and wait for it to be reflashed.
Warning! Home Power combination is the entry of the phone into the so called “Recovery mode” (DFU). It is used to update the software or to reinstall it in those cases when the phone does not work properly due to a software failure.
For iPhone X and other phones that don’t have a physical Home button, entering DFU mode is done by pressing Power and Volume buttons-. Exactly the same way: hold for 10 seconds, then release the Power key and keep holding the Volume key until the computer recognizes the device (the iPhone recovery mode detection dialog box appears).
Problems with the power controller
Apple smartphones. These are devices where everything is well thought out. There is a special chip that controls the incoming voltage when charging. The battery of the phone is powered from the AC network, through a special adapter. Before reaching 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 requirements of the battery, it charges, but when it is higher, the chip triggers, preventing the pulse from reaching the battery.
If the iPhone shuts down on its own, it could mean that the power controller is broken. In this case, the phone’s operating system tries to “protect” the battery from power surges.
Only specialists of the service center can fix the situation. You will need to replace the faulty power controller. This process involves working on the iPhone system board, where unprofessional actions will lead to the complete uselessness of the device.
If you don’t want to back up your data and restore the system try to clean your phone from the latest installed tweaks or check the file system.
If iPhone does not start and the apple is lit, it may be because of the incompatibility of tweaks installed from Cydia. To test the hypothesis, try running the smartphone without tweaks. To do so:
If in this mode iPhone boots normally, you should get rid of the tweaks that were installed just before the appearance of problems with booting the system. Remove the interfering component, and the system will start functioning again without crashing.
If iPhone won’t boot without tweeks, restart it. After a few minutes try to make a call or send an SMS. If the call or message went through, it means that the system booting is interrupted at the stage when the device is trying to contact the file system. Using the iTools or iFunBox program, you should get the damaged files and replace them with working data.
If the call does not go through, or you cannot locate the files responsible for the error, you will have to perform iPhone repair to fix the problem.

Why does the iPhone turn on and turn off by itself?
Yes. From a situation when the iPhone turns on and turns off by itself there is indeed a way out. It is necessary to try to eliminate the problem, the good news is that there are a sufficient number of ways to do this. But they all differ depending on what led to the bug. So first it is necessary to understand the causes and only then proceed to drastic actions.
The battery is dead
The most common reason why your phone powers down is. Of course, an iPhone owner may exclaim that the screen showed 10 or even 15% of battery power at the time of shutdown. But the fact is. Even in this case, the iPhone shuts down on its own if it has been in use for several years.
In order for the iPhone to always show the actual level of charge, it is necessary to periodically calibrate the battery.
It is also impossible to exclude that the user simply did not notice how the battery charge is reduced to a critical value. The device can not display the information on the screen, and therefore it shuts down.
Another very common case that causes the smartphone to reboot. Despite the fact that iOS is a closed system, lags happen even during its operation.
The user may accidentally download a malicious fact that will make adjustments to the operation of the device. It is likely that due to a virus, the battery calibration is thrown off. The screen may display some information, but the actual battery turns out to be low.
In addition, individual viruses behave even more cleverly. They literally make the iPhone think it is time to charge it, although there is no real need to do so. The device shuts down, not allowing the owner to continue watching videos on YouTube or play games.
Finally, the software bugs can be caused by the incomplete firmware. Yes, Apple is trying to hone the operating system to automatism. But even such a proven manufacturer has difficulties with optimization. Especially often “raw” manifests itself on new versions of iOS, which are installed on older phones.
The situation can be reversed when the owner has not updated the operating system for several months, but installs more and more new applications. Third-party software adapts to current iOS, and support for outdated modifications fades into the background. That’s why the smartphone malfunctions. As a consequence. Iphone shuts down for no apparent reason.
Of course, the case is not limited to the battery depletion and software malfunction. There are other causes of the problem. Here is an incomplete list of them
- The fall of the phone;
- Moisture entering the case;
- Battery failure;
- The incorrect operation of some applications;
- Improper installation of updates.
Iphones very often deactivate in freezing temperatures. Apple devices are very sensitive to cold, so they forcefully deactivate if the air temperature drops below zero.
Since the topic is still unexplored to the end, there is a possibility that the list above will be added to one or two more reasons. But even the known causes need a separate comment, because the iPhone owners do not always take them into account when using it.
First, it is worth touching the moisture protection. All Apple smartphones from iPhone 7 to later feature IP67 protection. It assumes that the device is not afraid of water or dust. But the standard does not guarantee safety in case of ingestion of aggressive liquids (juice, coffee) or hot water under pressure. In such a situation, none of the existing standards will help. And the shutdown of the smartphone is a consequence of careless use of the gadget.
Secondly, the functioning of the device is strongly affected by falls. Even the slightest bump on the iPhone can make it unstable in the future. No wonder iPhone shuts down on its own.
Finally, the problem may arise due to the expiration of the recommended period of operation (2 years) and incorrect installation of updates. The latter situation happens especially often, because during a reflash, iPhone owners ignore the recommendation to perform a factory reset. Installation occurs with errors, causing a forced shutdown in some scenarios.
To determine the exact cause of the error you need to remember how you have recently used your iPhone. It will also be important to make sure that the disconnect does not occur in a particular application, but in completely different scenarios.
Apple devices are no less prone to system failures than other phones. There can be a variety of causes:
- Very high load on RAM because of running a large number of programs in the background mode.
- A wrongly performed jailbreak.
- Incorrect device firmware, etc.Д.
If a hard reset does not solve the problem, it makes sense to perform a recovery of your iPhone, backing up your data beforehand. You will need a computer with iTunes to solve the problem.
Important: During repairing process all information will be deleted from the phone, so make sure you backed up your data before flashing.
- Connect iPhone to your computer with iTunes open.
- Put the device into DFU mode. Hold Power and Home for 10 seconds, then release the Power button and hold Home for another 10 seconds until iTunes displays a message that your smartphone is in recovery mode.
If restoring in DFU mode does not solve the problem, there is a good chance that the cause of the problem is a hardware malfunction.
Repair iTunes (data loss)
If the solution suggested in the previous part of the article proves ineffective, then there are more serious problems with your iOS. You can fix them with Tenorshare ReiBoot’s “Deep Repair” feature, but it’s important to keep in mind that this will result in the loss of all personal data stored in the iPhone memory.
Repeat steps.2 of the previous instruction, but this time mark the second tile and click the “Deep Repair” button.
All data and settings will be erased, so the phone will need to be set up as a new one by authorizing in your Apple ID.
