In the 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 all models of iPhone X / 8/7/6/5/4 and their modifications S and Plus.
iPhone is the accessory that provides endless communication possibilities, while being a stylish gadget that emphasizes the excellent taste of the user. Every day, people spend a lot of time texting with each other, calling, surfing the Internet.
The smartphone has taken a big place in human life. It is all the more offensive when the device malfunctions during operation. Serious Malfunction - iPhone shuts down by itself. During an important conversation or correspondence, the device may simply go out, causing a lot of negative emotions. There are several reasons and ways to fix the trouble. Let's consider each separately.
Battery problems
This is the most popular, common reason. The malfunction can occur in several cases.
- The phone fell, causing the battery contacts to disconnect. But this phenomenon is not permanent. The fact is that the contacts did not break off, but simply disconnected and now spontaneously change position. The smartphone may work fine, but as soon as the owner shakes it (by pulling it out of his pocket or in some other way), the contacts of the 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 cheaper Chinese counterparts are installed when replacing the "native" battery. The capacity of these batteries may be insufficient a priori. But the phone will still work. Only during operations that require a lot of energy (Internet surfing through the switched on Wi-Fi and simultaneous conversation on the cellular line), a power surge will occur, and the battery capacity will drop to zero - the phone will turn off.
- The battery is defective. Each battery has its own specific recharge limit, after which it begins to deteriorate. Another situation is when the iPhone is exposed to temperature extremes - for a long time arriving in a too warm or cold environment.
How to fix
If the loop contacts break, you should contact the service center - it's good if the iPhone warranty is still valid. An independent unskilled solution to a problem is fraught with more disastrous consequences.
When a non-original battery is used, the way out of the situation is simple - change to 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 worked out, then we proceed in the same way as in the previous method - we buy a suitable original battery. There is one important point here. 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 refer the iPhone to specialists who will quickly change the battery for a modest fee.
Power controller problems
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 AC power supply through a special adapter. Before getting into 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, then charging is in progress, and when it is higher, the chip is triggered, preventing the pulse from reaching the battery.
If a iPhone turns off by itself, it may mean a breakdown of the power controller. In this case, the phone's operating system tries to “protect” the battery from power surges.
Repair method
Only the specialists of the service center can correct the situation. Replacement of the failed power controller will be required. This process is associated with work in the iPhone motherboard, where unprofessional actions will lead to the complete unusability 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. Certain software bugs cause the iPhone to turn off by itself when fully charged.
How to fix the situation
The first and easiest option is to completely reboot the device. To do this, you need to simultaneously hold down the power and Home buttons. They should be held in this position for at least 15 seconds. If the restart 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. The fix is \u200b\u200beasy:
- We completely discharge the iPhone.
- We leave it in this state for 2-3 hours.
- Then we connect the charger.
- We charge up to 100%.
Another way to deal with errors is to restore the operating system. The process is carried out through the iTunes program (any user of Apple devices has it). Then we get a completely "clean" gadget with the newest (available) operating system. Before restoring, in order to avoid the loss of important information, you should make a backup copy of the data in the same iTunes or save it on the iCloud cloud server.
Conflicting Applications
There are applications that, when activated, conflict with the operating system. This is caused by the incompatibility of the program and the IOS version, the result of which is the device shutdown. There are two ways out of the situation.
- Upgrade your operating system if available.
- Remove conflicting application.
Some programs require additional hard disk space. An example would be a photo editor that processes an image by saving the result separately without touching the original. When there is not enough memory, the system can react by turning off the phone. Exit: free up space on your hard drive or not use the application.
iPhone may shutdown due to CPU overload caused by a large number of concurrent applications. The component is overheating and to protect it, the operating system gives a shutdown command.
Water ingress
Water, along with dust, is the main enemy of digital technology. If moisture gets inside the gadget, the device stops working correctly. This can manifest itself in the fact that iPhone turns off by itself and turns on only with charging... In order not to ruin the device completely, you should contact the service center, where the phone's iron will be dried. It is not recommended to get rid of moisture inside the smartphone on your own.

the iPhone is a very stable and reliable phone. Unfortunately, even with it, problems can occur. We will try to figure it out today with one of the common problems "iPhone turns off".
Your gadget worked and then it started, at first it rebooted, then turned off completely, and it was possible to start it only by pressing two "Home + Power" keys for 20 seconds.
These are the first signs that something is wrong with the phone.
Let's start with the simplest. Check free space on your phone, it may well be that the memory is completely clogged, and programs intermittently crash, as a result of which the iPhone restarts or turns off. To do this, go to Settings - General - About this device. See how much memory you have available, preferably more than 2 GB. If it is less, then it is time to start deleting "unnecessary" programs, music and photos.
We have enough space, but the iPhone still restarts. You need to decide on such a step as a complete flashingphone with deletion of all data. This is necessary in order to reject software glitches. To do this, you need iTunes installed on your computer. Turn it on, connect the phone, press the Restore button. After that iTunes will do everything itself. And the phone will be flashed to the latest iOS.
Checking our iPhone. And it reboots or shuts down again. You will have to contact the service... As practice shows, the problem lies most often in the battery. In a professional service, like ours, you will of course be offered to make diagnostics, since the probability of a bad battery, although higher, is not one hundred percent, the problem may lie deeper in the motherboard. Very often, customers hope to chance and simply ask to change the battery. Replacing the iPhone battery in our service without diagnostics takes only 15 minutes.
The battery replacement option helps many. But as I wrote above, not always. In this case, you need to prepare for a major overhaul of the motherboard. It is advisable to try to determine at what point the device reboots or turns off. This can be, for example, using the 3G or LTE Internet, using Wi-Fi or it turns off even if you do nothing and just open the desktop. This information will help localize the problem and fix it as soon as possible.
The main reason for problems with the motherboard is the frequent drops of the phone. Microcracks appear, causing the iPhone to behave unstable and start to reboot and shut down. Therefore, be more attentive to your phone and drop it less, then you do not have to drive the phrase "iPhone turns off by itself" into the browser line.

Owners of the seventh iPhones should take into account the fact that the activation process for the iPhone 7 and iPhone 7+ is different, due to the presence of the Home button in the newer model. To turn on your gadget, you need to simultaneously hold down the power and volume down keys and hold them in this way for about twenty seconds, after this time, the Apple logo will appear on the screen.

Why iPhone 7 may not turn on after an update or restore operation?
This question torments the minds of many iPhone 7 owners. During such processes, the iPhone 7 may well turn itself off and turn it on using standard methods is no longer possible. Most often there are two reasons for this.
The first reason is the breakdown of the GSM module, or more precisely, the Nor Flash microcircuit, designed to adjust the device's services for the SIM card of the cellular operator.
