Example. On December 2, 2017, many iPhone owners began to reboot on their own. 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 those from unofficial publishers, can cause devices to malfunction. 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 an emergency shutdown is always recorded after the activation of a certain function or installation of an application is recorded.

Periodic shell updates can also play a cruel joke on a 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 carried out correctly, and also check its compliance with the technical capabilities specific model iPhone.

If software or itself operating system models are not the cause of the shutdown, which means the failure lies in the hardware of the smartphone. In this case, you need to contact specialists service center 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 disrupt stable operation. Please note that over time any iPhone gives “play” - a small gap between the fixing elements of the device cover.

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. Such a “breakdown” in the electrical signal transmission circuit leads to the device turning off when its position suddenly changes. 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. Usually malfunctions, as well as complete burnout central processor restored by replacing the component.

Quite rarely, but it still happens when the user Apple gadgets The question arises: why does the iPhone reboot on its own? However, this problem does happen, and can happen with both old model, so with latest versions phones on the iOS platform.

Restart due to software glitch

First, let's consider a solution to the problem with newer iPhone versions. Implemented in these devices additional option— an event recorder that records all actions of the user and the system itself during the operation of the smartphone.

If your phone keeps rebooting, go to the event log and see which application was last opened or attempted to update before the crash was recorded. Thus, you can determine which program or system file creates a conflict between itself and the operating system, causing an involuntary reboot.

This kind of trouble can happen when a user installs an application or game from a non-official source. It’s not for nothing that you don’t trust those applications in the AppStore that are incompatible with your phone. The system automatically detects the device model and hides programs that are not suitable for it.

If you are the owner of a phone that is older than the iPhone 5S and 6, which does not have the event viewing function, then you can determine the cause of the failure only by analyzing the last manipulations before the next reboot. This way you can catch the program that is causing the problem by the tail.

Cause of hardware failure

The most common failure that leads to an iPhone reboot is the loss of contact between the battery and the device board. This defect can be observed if the gadget turns off during shaking or a normal conversation on the phone. Due to vibration, the contact is lost, which leads to a shutdown.

It is quite difficult to fix such a breakdown on your own. The best way out of the situation is to take the iPhone to a service center, where professionals will take over the matter.

Apple smartphones have always been distinguished by excellent performance, wide multimedia capabilities and a high level of reliability. But even latest iPhones Over time, they may malfunction, and one of these problems is the periodic reboot of the device, which can happen both during charging and during use.

If your iPhone begins to turn on and off on its own, you should urgently send it to a specialized service center, where competent specialists can solve this problem.

Why does my iPhone reboot itself?

This problem is most often caused by problems with the battery, especially if the device is several years old and it was not charged according to the rules, namely:

• instead of the original cord, an iPad charger was used;
• During charging, power surges often occurred;
• The iPhone was charging in the car.

The main factor in the breakdown is instability of the current level, but the battery can also become unusable for the following reasons:

• loss of contact between the battery and the smartphone or its deformation as a result of an impact or fall;
• moisture getting inside the device;
• software glitch;
• malfunction of the power amplifier that regulates the current in the device.

If your iPhone suddenly starts rebooting, and turning on is difficult, then you should not look for the cause of the breakdown and carry out repairs on your own, since this can only make things worse and aggravate the problem. In such a situation, you must immediately contact professionals who can accurately determine the cause of the malfunction and carry out the necessary repairs.

Some users have complained about frequent random reboots of their iPhone. The problem is quite common, and various factors can affect it. You can learn more about them in this article.

The occurrence of such a problem can be influenced by various reasons related to both the software component and hardware faults.

Reason 1: Firmware failure

An incorrectly functioning iOS operating system can cause the phone to reboot spontaneously. In this case, the problem can be solved by flashing the device.

Reason 2: Battery wear

With daily use of the iPhone, the battery capacity begins to gradually decrease after a year. After two years, the battery is considered severely worn out, which can affect not only the operating time of the phone on a single charge, but also the appearance of random reboots. Battery wear can occur much earlier due to improper use:

• The phone was often connected to the iPad charger;
• During charging, power fluctuations occurred (very often a similar problem is observed when iPhone connection to the cigarette lighter in the car);
• A physical malfunction, which, for example, could have occurred due to moisture getting under the iPhone case or the battery being deformed as a result of a fall.

Reason 3: Improper operation

External factors, such as cold or, conversely, increased temperature, can cause the phone to suddenly reboot. Apple notes that the optimal operating temperature for the iPhone varies between 0-35 degrees Celsius. iPhone storage allowed from -20 to +45.

Anything above or below the specified temperature indicators worsens the operation of the device and, in particular, can lead to a sudden reboot of the phone. In this case, you should ensure a comfortable temperature, remove the cover for a while, after which the problem will resolve itself.

Reason 4: Hardware failure

If you have ruled out all three reasons discussed above, you should assume that the problem is a hardware malfunction, for example, motherboard. In this case, you should contact a service center and have your smartphone diagnosed. The specialist will tell you exactly what the problem is: if it really is a part, it will be replaced.
