iPad turns on and off immediately. iPhone turns on and immediately turns off: how to restore a smartphone

Reading time: 4 min

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 iPhone X/8/7/6/5/4 models and their modifications S and Plus.

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

The smartphone has taken an important place in a person's life. It is all the more offensive when the device malfunctions during operation. Serious malfunction - iPhone turns off spontaneously. During an important conversation or correspondence, the device may simply turn off, 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 reason. A malfunction may occur in several cases.

1. The phone has been dropped, causing the battery contacts to become disconnected. But this phenomenon is not permanent. The fact is that the contacts did not break off, but simply disconnected and now spontaneously change their position. The smartphone may work normally, but as soon as the owner shakes it (by pulling it out of his pocket or in some other way), the iPhone battery contacts will disconnect from the power board, which will turn off the device. The charge level does not matter.
2. Non-original battery. This happens when, when replacing a "native" battery, cheaper Chinese counterparts are installed. The capacity of these batteries may be a priori insufficient. But the phone will still work. Only during operations that require a lot of energy (Internet surfing through the included 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.
3. Battery defective. Each battery has its own specific recharge limit, after which it begins to become unusable. Another situation when the iPhone is subjected to temperature changes - for a long time arrives in an environment that is too warm or cold.

How to fix

If the cable contacts break, you should contact the service center - it’s good if the warranty on the iPhone is still valid. An independent unqualified solution to the 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. 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 its own, then we proceed similarly to 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. On the Internet you can find a lot of instructions on this subject. But reality is sometimes different. In addition to skills (or at least experience), the user will need special tool. Its cost varies. It will be easier to immediately take the iPhone to specialists who, for a modest fee, will promptly change the battery.

Problems with the power controller

Smartphones from Apple are devices where everything is thought out. There is a special chip that controls the voltage supplied during charging. The phone's battery is powered by AC power through a special adapter. Before entering the battery, the voltage passes through the power controller (the same chip). It plays the role of a barrier that prevents damage to the battery. When the voltage meets the requirements of the battery, then charging goes on, and when it is higher, the chip is triggered, preventing the pulse from reaching the battery.

If iPhone turns off by itself, then this 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 specialists can fix the situation service center. You will need to replace the failed power controller. This process involves 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 features. 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 bugs cause the iPhone to turn off by itself when fully charged.

How to fix the situation

The first, easiest option is to completely reboot the device. To do this, you need to simultaneously hold down the power and "Home" buttons. Hold them in this position for at least 15 seconds. Upon successful reboot, 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 a bug 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 ​​easy:

• 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 percent.

Another way to deal with errors is to restore operating system. The process is carried out through the iTunes program (any user has it Apple devices). After that, we get a completely “clean” gadget with the newest (available) operating system. Before restoring, in order to avoid losing important information, you should backup 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 an incompatibility between the program and the IOS version, which results in the device turning off. There are two ways out of the situation.

1. Update the operating system, if available.
2. Remove the conflicting application.

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

iPhone may shut down due to CPU overload caused by big amount concurrently used programs. 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 may manifest itself in iPhone turns off by itself and only turns on when charging. In order not to completely ruin the device, you should contact the service center, where the phone's hardware will be dried. It is not recommended to get rid of moisture inside the smartphone on your own.

What to do if the iPhone suddenly turned off as if the battery ran out, but in fact it is charged. If you have problems with an iPhone or iPad that turns off by itself when the battery is charged, use our instructions. See what to do if the iPhone starts turning off by itself.

As a rule, an iPhone, so, however, any other mobile device, when the battery level drops to a critical value, turns off. But sometimes there are failures in the operating system or with the battery, despite the fact that it is charged. Why does the iPhone turn off by itself?

Unfortunately, iPhone shutdown issues are not model-specific. Based on discussions on the forums, most often the problem occurs on the new models 6, 6s and 7, but from spontaneous shutdown old devices are not insured - iPhone 4s and iPhone 5s.

But keep in mind that the iPhone can turn off, for example, in the cold or frost - this is a standard operation aimed at protecting the device from damage.

Let's move on to ways to eliminate the spontaneous shutdown of the iPhone.

The first way is to update the operating system

The first method from which to start searching for the cause and restoring the normal operation of the iPhone is to update the software version. Sometimes it will be enough to perform a normal update so that the phone stops turning off by itself. Especially updating the system is relevant in those cases, for example, if you previously used a test version of iOS on an iPhone or iPad.

To do this, go to the Settings application, then on the General tab - Update, check if there is a new one available. iOS version for our smartphone. If yes, install it and wait for the iPhone to reboot.

The second way is to reset the settings

Restoring factory settings is also a very simple method, which can be extremely useful when errors occur in your smartphone. If the iPhone turned off by itself for the first time (before this, there were no such problems, except when it turns off in the cold) and you assume that the problem is not in the battery, turn it on again.

If the restart did not help and the iPhone still turns off by itself, proceed to restore the factory settings. To do this, open Settings, then go to the General tab and find Reset. With it, you can erase all data and return iPhone to the initial state. But before performing a reset, you should make sure that you:

• made a backup copy of all data;
• disabled in settings account iCloud.

The first item is needed in order not to permanently lose all our files, especially contacts. The second will allow you to perform a full reset of the iPhone. Without turning off Find My iPhone in the iCloud tab, you won't be able to reset your phone to factory settings.

If the problem persists and the smartphone still turns off by itself, we will try to charge the battery. First you need to completely discharge the battery - to zero. But before that, be sure to make a backup copy of all data - as in the previous method.

When the battery is low, we connect the iPhone to the charger better through a proven cable.

If, for example, a problem with the phone arose due to a malfunction of the charger, then we simply won’t charge the iPhone. If you are not sure about your charger, you should test how the phone charges using a USB cable connected to a computer.

The fourth way is to update the firmware via DFU

If you are not afraid to damage your phone, you should try putting it into DFU mode. Then install the latest iOS operating system using a computer and iTunes.

The method will allow us to update our smartphone in a 100% safer way. If the iPhone turns off by itself through failures in the operating system, then DFU mode should solve them once and for all. In this case, you also need to back up your data and disable your iCloud account first. That is, just like in the second method.

If these methods did not bring desired result and the iPhone still turns off by itself, you need to take it to a service center. Even if the smartphone is not under warranty, this should be done. Diagnostics to find out what is not working in our iPhone can be absolutely free, and thanks to it we will at least know whether it is worth investing in repairs or start saving for a new device.

If your iPhone is behaving strangely turning off on its own, even with 15% or 30% remaining battery, then you should know that this is not news and you are not the only one experiencing this problem. Users have been reporting this issue all over the place since the release of iOS 9. And even now in 2016, many of us are still facing this issue.
If your iPhone suddenly turns off even though there is sufficient battery power, try the following troubleshooting tips:

1. Perform a hard hard reset

Usually a hard reset solves this problem. A hard reset is similar to the procedure: “did you try turning the device off and on again”, but at a deeper level of the operating system. Usually reset occurs to factory values.

To hard reset your iPhone with a physical home button (any iPhone model to iPhone 7), press and hold both “ Sleep/Wake" And " Home” within 5 seconds. The iPhone will restart, you will see the Apple logo flashing and the iPhone will come to life.

Articles and Lifehacks

"Apple" technology is famous for its high quality; for the same reason it is valued for its reliability. Unfortunately, many of its owners have a situation where the iPad turns on and immediately turns off.

This often happens for no apparent reason, with a fully charged battery and, of course, at the most inopportune moment. In this article, we will show you how this problem can be solved.

Tablet shuts down immediately after booting up

For starters, you should still connect the tablet to a power source and check how charged the battery is. If after some time the problem recurs with a fully charged battery, it is quite possible that it simply failed.

A more radical method (which, nevertheless, often helps to fix the problems that have arisen) is hard reboot devices. This will reset all temporary information.

• Press and hold the on/off button and the home button at the same time.
• We leave our fingers in this position until the "apple" logo appears, or a notification about the battery charge is displayed.

If none of the above helps, you can also try the following steps.

Tablet shuts down before download is complete

Often a real salvation can be the restoration of the device, that is, the restoration of its system. This is a fairly simple procedure, and anyone can do it. To do this, use the "Reset" section through the main settings of the tablet.

If you wish, you can perform a system restore in another way. For example, iTunes can be used for this purpose.

1. Convinced that before us is his latest version, create a backup copy of the device (this must be done to prevent the loss of important information).
2. We move all the data to a PC or laptop and perform synchronization.
3. We connect the tablet to the computer.
4. We find our device in the tab on the left and click on it.
5. In the "Overview" section, we find the restore button on the right and click on it.
6. We confirm our actions by pressing the same button again.
7. After that, the iTunes app should download software tablet, after which the restoration of its original settings will begin.

At the end of this process, a reboot will be performed. We will only have to set up the tablet, using the tips of the setup wizard. In addition, it will be possible to restore from the previously created backup.

If none of the above helped, it is quite possible that there is a hardware failure. In this case, it is best to seek help from specialists.

Hey! To begin with, it is worth describing the situation in more detail, otherwise it may not be clear from the title what the author means. Moreover, I recently encountered this problem personally, so the picture is right before my eyes and it will not be difficult to describe the situation :) And the following happened - my rather old iPhone 5s was completely discharged, as they say "to zero", and it would seem that there is nothing criminal, plugged it in and went about my business...

I return after a while, and I see a very strange and inadequate behavior of the device - the iPhone turns on, the screen lights up for a while (an apple appears and even a glimpse of the password entry) and immediately the display goes blank and the phone turns off safely. And that's what happens all the time. For the sake of the experiment, I waited another 20 minutes - nothing has changed (only), but continued to turn on and off with enviable constancy.

I’ll run ahead and say that I managed to solve the problem on my own and without visiting a service center, and in a fairly easy way. But first, about how to prevent such a situation and what you should pay attention to:

1. Do not discharge the device until it is completely discharged, especially if the battery is no longer new.
2. Do not try to force it, in cold weather you need a lot more energy to start.
3. Use original accessories - the battery will only thank you.

Actually, almost all these reasons coincided with me - it was relatively cool in the room, the battery has definitely been there for a couple of years (although it holds), only the wire and charging are original.

What happens in the end? When connected to a charger, it turns out that all incoming energy is spent solely on loading the system and backlighting the display. This energy is not enough, it cannot accumulate, the iPhone seems to turn on, but immediately discharges and turns off. And then everything will repeat again. Here is such a vicious circle.

How to get out of it?

• Use a more powerful power adapter. The one that comes with the iPhone gives out 1 ampere and it is clearly not enough in such a situation. So you need something stronger, for example, from the iPad. It has 2.1 amps at the output and is able to provide more energy, which is enough to turn on. Is it safe? Apple says that, and it makes no sense not to believe it.
• In the case when there is no other adapter at hand, you need to do the following operation - and leave it on charge for a while in this state. In this mode, the screen does not light up and the system does not boot, which means that there will be no energy consumption and all of it will go to charge the battery. After 20-30 minutes, we turn on the iPhone and are glad that the shutdowns have stopped.
• This option is clearly "an amateur" and will require some skill from you. It consists in connecting the wire to the device for 2-3 seconds and without waiting for it to turn on, immediately pull it out. And in such small portions, recharge the battery to the state that is enough to fully launch the iPhone.

Finally, I would like to note that the situation discussed in this article is, of course, not normal and in a good way, the battery must be changed so that there are no other surprises in the future. But here everyone decides for himself.
