• iPhone 4 turns on by itself. How to solve the problem with iPhone turning off spontaneously. iPhone is in DFU mode

    When using Apple technology, an unpleasant situation often occurs when your iPhone turned off and won't turn on. This scenario applies not only to iPhone smartphones, but also to the popular line of iPad tablets. In these cases, you should not sound the alarm in advance, get upset, worry, and especially not take your Apple gadget to a special service center. First, calm down, carefully consider your actions and follow the instructions below.

    In the vast majority of cases, a number of similar situations are not even a breakdown; the device simply stops responding to button presses and does not turn on. Use two universal methods that will make your device work.

    The main two reasons why and refuses to work, it is either a low battery charge in the smartphone, or a banal system freeze, which has recently been increasingly happening with Apple technology.

    These problems do not relate to hardware or, especially, software errors, for the solution of which it is necessary to take the device to specialists or repairmen.

    You can solve the problem yourself by connecting the phone to the charger and leaving it in a quiet state on charge for 10 - 15 minutes. The battery icon should light up on the black screen of the gadget. This means that the device's battery is completely discharged and you need to wait a bit. After the specified time, try turning on the smartphone without unplugging the device from the outlet.

    If the reason is that your iPhone or iPad is frozen, you need to force reboot the system.

    The screen is dark and the iPhone does not turn on - does not respond to button presses

    The option when the iPhone does not turn on, much less respond to button actions, has recently become a fairly common occurrence in Apple phones and tablets.

    The standard situation occurs as follows: the iPhone or iPad has not been used for a long time, while the device is fully charged. At one point, for reasons unknown to you, the gadget turned off and no longer wants to turn on. At the same time, pressing the start key of a smartphone or tablet, the screen does not light up. What to do and what to do if your iPhone or tablet does not turn on?

    The main thing is not to panic. There is nothing scary or dangerous about this, since mobile devices can go into “save mode” from time to time, which is similar to the indicated symptoms, especially when the gadget is rarely rebooted and used.

    A universal method for “reanimating” an iPhone or iPad tablet

    If your iPhone or iPad tablet is charging but won't turn on, use a simple sequence of actions that is suitable for most models of the manufacturer and will help “reanimate” a frozen device: press and hold the “Power” key and the “Home” button at the same time for 10 to 20 seconds. As a result, the apple logo should light up on the gadget’s screen, and the device will continue to load.


    These instructions apply to the following manufacturer gadgets:

    • iPhone 2G;
    • iPhone 3G;
    • iPhone 3Gs;
    • iPhone 4;
    • iPhone 4s;
    • iPhone 5;
    • iPhone 5c;
    • iPhone 5s;
    • iPhone 6/6 Plus;
    • iPhone 6s/6s Plus;
    • iPhone SE;
    • Any version of the iPad.

    If the iPhone still does not turn on, the apple lights up and the screen goes blank, most likely the error is more serious, hardware or software. In this case, you need to either change the charger or the phone battery. This can be done at a company service center.

    Method for new versions of iPhone 7 / iPhone 7 Plus smartphones

    The option for turning on Apple's new smartphones, iPhone 7 and iPhone 7 Plus, is not much different from the universal method. This is due to the fact that the “sevens” have a built-in touch “Home” key instead of a mechanical button. By simultaneously pressing and holding the “Power” button and the volume down key for 10–20 seconds, the user activates a special wake-up mode for the phone. The company logo will appear on the display and the device will boot into normal mode.


    Quite often, a mobile gadget may freeze while one of the programs is running, which caused the iOS system to malfunction. In this case, the buttons do not work, and it is necessary, by analogy with the previous situation, to start the process of forcing the phone to reboot.

    The above examples constantly arise with most of the manufacturer’s devices. A list of guidelines solves the vast majority of them, but if you're unlucky and your device still won't boot, then it looks like you might be experiencing one of the following problems.

    Many iPhone owners are familiar with the problem of the gadget turning off spontaneously. Moreover, the iPhone often turns off even in cases where the gadget’s charge indicator shows an almost full battery. There may be several possible reasons for such unpleasant behavior of your favorite smartphone. Let's look at three main ones.

    Reasons why iPhone turns off spontaneously

    1. Battery malfunction.
    2. bugs in iOS.
    3. battery indicator error.

    Battery fault

    In the event of a battery failure, the iPhone can turn off and on either with or without the charger connected. You won’t be able to solve the problem yourself, since the issue is replacing the battery. In this case, you will need the help of service center specialists. The cost of the service is about $100. But before you rush to get your iPhone repaired, it’s worth considering two other possible options for the problem that has arisen.

    iOS Bugs

    If the reason lies in the system update, then it is possible to identify and resolve it yourself. True, this process is very labor-intensive. You will need a clean installation of the system. Why the iPhone turns off due to updates is a complex question, but it is known that when updating to the latest versions, a kind of baggage of unnecessary garbage accumulates in the system. And it is also the main reason for the rapid discharge of the battery.

    So, the “treatment” of the problem consists of the following actions:

    • connecting iPhone to iTunes;
    • a complete local backup of all existing files and other stuff located on the gadget;
    • clicking the “Restore” button;
    • restoring a backup.

    After these manipulations, your iPhone will not need to be repaired, and you will be able to once again enjoy the trouble-free operation of your favorite gadget.

    Battery indicator error

    Sometimes the battery indicator may also give incorrect data. Fixing this problem is as easy as shelling pears. You will need to completely discharge your gadget (to zero), wait a few more hours to be sure, and then charge (without turning on) the iPhone to 100%. Do not interrupt the charging process! As a rule, after such actions, the indicator again shows the correct charging percentage and expensive iPhone repairs become unnecessary.

    Unfortunately, even with such a high-tech and reliable device as the iPhone 6 Plus, an unpleasant situation can happen.

    Violation of operating conditions, an absurd accident, and sometimes a manufacturing defect can cause a smartphone to fail. One of the most common problems is when the device does not respond to pressing the “Power” key.

    Sooner or later, most iPhone users face this issue. The problem of iPhone not being able to turn on is quite common. Each generation of iPhones has its own characteristics of this problem. The first thing you need to do is connect your iPhone 6 to the original charger.

    Most often, the culprit of the breakdown is the “Power” button itself, which has a damaged contact pad or cable. The reason most often lies in moisture getting inside the case or mechanical damage to the part caused by the phone falling. Also, often a smartphone’s failure to turn on is due to a serious software glitch or failure of the power system controller.

    Why and how to solve

    There are many reasons why the iPhone 6 turns off and won’t turn on.

    They can be broadly divided into the following:

    • complete discharge of the device;
    • software problems;
    • hardware problems.

    Software problems are easier to solve; in a situation with hardware problems, the solution is more complex and expensive.

    Software glitch

    The most common reason why an iPhone won't start is a software glitch. To fix a software glitch, you need to do a hard reboot of the device. To do this, press and hold the Power key and the Home key simultaneously for 15 seconds. As a result, the device will reboot and will be available for normal operation.

    If this does not help, then you need to try to put the device into recovery mode. To do this, hold down the “Power” and “Home” buttons for 30 seconds.

    In a situation where such a basic solution to the problem along with thoroughly charging the battery did not solve the problem, the possible reason for the non-working device is as follows:

    • The gadget’s battery is faulty (needs to be replaced with a new one);
    • The adapter or USB cable is damaged (the adapter or USB cable needs to be replaced);
    • The cable connector is dirty (it is necessary to clean the cable connector);
    • low-quality (cheap) cable (replace with an original one);
    • mechanical damage to the connector and other mechanical damage, for example, due to a fall, moisture, after charging in a car, etc. (you need to contact the service center);
    • defect (you must contact the place of purchase).

    It is also possible that the iPhone may not turn on after updating the firmware.

    There are three different scenarios depending on when the failure occurred during the firmware update:

    • reflash the phone again;
    • replace the faulty NAND Flash. This is a memory chip on which all the owner’s personal data is stored;
    • replace the failed Nor Flash. This is the GSM module memory chip. All parameters of mobile operators are stored there. Without these parameters, the device will not be able to make calls.

    Power and charging problem

    If you can't turn on your iPhone 6, then most likely there is a problem with the power or charging. First of all, you should try to charge it. Moreover, you need to connect it to the charger for at least 20 minutes from the adapter and 30 minutes from the workstation.

    After this, you need to try to start the iPhone without disconnecting it from charging. If everything is normal, the display will show a symbol of a lightning bolt inside a low battery.

    When the battery of an Apple smartphone is completely discharged, after a short charging, when you press the power button, the display displays a picture showing a socket with a lightning bolt symbol.

    The way out of this situation is to charge the device for a longer time. In this case, the charging time must be at least 3 hours.

    There are situations when the connector through which the phone is charged fails when using a non-original charger.

    It is very important to know how to easily charge your iPhone 6 in a car, and even more important to follow these basic rules. This leads to serious consequences. At best, the iPhone battery needs to be replaced. At worst, this means replacing the power controller or repairing a failed power circuit.

    iPhone 6 could

    In addition to problems with the battery, the iPhone not turning on can be explained by human error. This is especially common when the phone is carried in a trouser pocket.

    The device connector becomes clogged with dust and dirt, and the next time you try to charge it, the iPhone simply breaks. This problem is not very serious, since any service center can fix it in a few minutes for little money.

    Fill with liquid

    Getting your phone wet or even flooding it with liquid is not uncommon. Problems with the iPhone can begin not only when it drowns in a pond, but even when it gets caught in light rain. In this situation, the gadget may begin to fail.

    In this case, cleaning the device or component repair of the motherboard is highly recommended. It is important to stop using the phone immediately if moisture gets inside the device.

    Solving the problem is not entirely trivial, so it is recommended to seek help from a certified service center and avoid problems that may arise in the future.

    Lose to the floor

    The problem with turning on the iPhone may be due to mechanical damage, namely falling to the floor. It is important to remember whether the fall occurred a certain time ago, since the peculiarity of this situation is that problems with the smartphone can begin to appear quite a long time after the fall.

    An impeccable appearance (no scratches or other visible flaws) does not mean that there are no problems with it.

    Alternatively, one of several cables may snap off:

    • power cable;
    • display cable;
    • battery cable.

    A more serious situation is associated with a soldering problem on the motherboard or damage to one or more microcircuits.

    iPhone users may encounter a situation where the device turns off and does not turn on. If you don’t consider the simplest options, when the battery simply wasn’t charged in time, then most likely the issue is a malfunction of the boot data block of the gadget’s operating system.

    This problem can be solved if you try to restore the partition by connecting your smartphone in DFU mode.

    Often, a hard reboot will help to remove the device from this situation, and if moisture gets inside it or there is mechanical damage, it is better to contact a professional.

    Often, owners of expensive Apple equipment are faced with the fact that the iPhone turns off at 20 percent. If you are familiar with this unpleasant problem firsthand, this article will help you cope with it. In a number of cases, you do not have to resort to the help of specialists and spend your money on repairs. Many problems can be eliminated on your own and quickly enough.


    Why does iPhone turn off and what to do about it

    If the indicator of your smartphone shows a sufficient charge level (for example, it is in the middle), but then the device suddenly turns off because it is discharged, this brings huge inconvenience. In some cases, you can cope with this problem on your own. Below are a few common problems with Apple smartphones and easy ways to solve them:

    • problem with indicator– the device shows incorrect data about the battery charge level and, for example, when the battery charge is 50, the device is actually already completely discharged; To cope with a malfunction of the indicator, you must first completely discharge the phone’s battery, and then fully charge it
    • problem with device software– in order to fix this problem, you should return to the factory settings – backup and restore, but do not forget to back up all data, as they may be lost
    • charge controller malfunction– if the problem lies in the power controller, it can be resolved with a simple hard reset; in order to perform a hard reset, you need to simultaneously hold down the “Home” button and the “Power” button until the Apple device turns off

    To troubleshoot software problems, launch iTunes and connect your smartphone to your computer, make a copy of the data, and then click the “Restore iPhone” button. All you have to do is restore the data from the backup, and your device will work correctly again.

    Don’t forget that at low temperatures, a charged battery of any iPhone model runs out faster than in warm conditions. Low temperatures do not affect the battery capacity in any way, but to prevent it from being discharged at the wrong time and running out too quickly, you can put on a special case and carry the phone in the inside pocket of your jacket. In the cold, it is recommended to avoid photography and other heavy loads. In such a situation, the phone may suddenly sit down at 80 percent, half, or 30 percent of charge.

    If your device suddenly turns off when almost fully or half charged, or charges too slowly and incompletely, the problem may be that you are not using the original charger, but a low-quality analogue. In this case, all you need is to replace the charger with a suitable one.

    Other signs of damage

    The fact that your iPhone turns off at 20 percent may not be the only “symptom” of a breakdown. Other common faults are listed below:

    • iPhone turns off when taking photos even though it's more than half charged
    • the phone charges to 3 percent or 1 percent and turns off
    • The smartphone turns itself off when fully charged
    • iPhone turns off and shows blue screen
    • the phone dies too quickly (may turn off at 70 percent, 60 percent, or 35 percent)
    • When the charger is connected, the battery does not charge or only charges halfway
    • The phone spontaneously goes into standby mode under high loads or even in their absence

    Most likely, if such signs appear, you will not be able to fix the breakdown yourself, and you will still have to seek the help of qualified specialists.


    When to contact specialists

    If you have tried all the above methods and your iPhone still shuts down at 40 percent, 15 percent, or 10 percent, you should contact a professional like Yudu. Perhaps the reasons why iPhones turn off are much more serious, and they are not related to software, but are related to the “stuffing” of the iPhone. It could be:

    • battery failure
    • cable failure
    • microcracks on the board
    • connector malfunction
    • other hardware malfunctions

    Experienced craftsmen registered with Yuda will conduct diagnostics and accurately identify the cause of the breakdown. Using special tools and original spare parts, they will perform all the necessary work - install a new battery, repair the connector, replace the cable, etc. Upon completion of the work, you will receive a working device that will serve you for a long time. The technician will provide you with a guarantee for all work performed and give you advice on handling your phone.

    Today we will talk to you about what to do if your iPhone turns off and won’t turn on. There could be a lot of reasons for this. We will look at everything and try to figure out what needs to be done to restore the functionality of the gadget.

    Changing the battery

    Well, the first option in which the iPhone turns off and does not turn on again is a problem with the gadget’s battery. Honestly, any equipment and spare parts have their wear and tear. Especially with daily and active use. So, if you suddenly encounter a similar problem, then try replacing the device’s battery.

    It is best to buy a new battery at a company store. Insert it into your gadget, and then try to turn on the device. Usually this method works. True, sometimes it may happen that the iPhone turns off and does not turn on at all because of problems with the battery. In this case, you will have to look for the root of the problem elsewhere. Which one exactly? Let's try to figure it out.

    Crash

    Before you run to the store for a new battery, you should try another rather interesting approach. As a rule, if your iPhone turns off and does not turn on again, then it is best to start working on the problem from this stage.

    The point is that no system is immune from errors. Crashes can lead to this behavior. So, we need to somehow fight this. Honestly, it's pretty easy if you know where to click. System failures are “treated” by simultaneously pressing the power button and the exit button to the main menu. Hold them in this state for about 12-15 seconds, and then see what happens. A system loading indicator will appear on the screen. That's it. Now you know what to do if your iPhone turns off and won’t turn on again. But things aren't always that good, right? Let's look at a few more options for the development of events.

    Battery charge

    True, before you get upset and rack your brains over our current problem, it’s worth looking at another funny incident. If your iPhone turns off and does not turn on again, you can try... charging it.

    Quite often, users do not notice how their gadget “sits down.” Moreover, in cases where the battery charge finally drops to 0%, the iPhone will stop responding to any attempts to turn it on. You will have to attach the charger to it and then wait for some time. After that, try turning on the gadget again. Did it work? Then everything is fine. Now you know what to do if your iPhone turns off and won’t turn on. And if it didn't work, what then? Let's try to understand this difficult matter.

    Drying

    Sometimes the reason that the iPhone turns off and does not turn on (does not respond to charging) may be due to simple moisture getting on the device. To be honest, even though they are now trying to create something “water-repellent,” it hasn’t worked out yet. Thus, you have to protect your equipment from moisture.

    If you suspect that your iPhone has turned off and will not turn on (does not respond to charging) due to water getting on it, then you will have to disassemble the device. After that, just dry all its parts thoroughly. That's it. After some time, try working with the gadget again. In cases where the reason lay precisely in moisture, this method will work flawlessly. But everything is not always so simple and easy. Let's look at why else this "behavior" might exist. There are still quite a few reasons, but they can all be solved. Although it is not always very easy to do this.

    Viruses

    And now we’re moving on to less pleasant reasons why you might be wondering what to do if your iPhone turns off and won’t turn on/won’t charge. The thing is that quite often this is a consequence of a system being infected with viruses.

    Yes, no one is safe from them now. Especially if you work a lot on the Internet from your gadget. Thus, it is likely that this is the reason. What should you do if your iPhone turns off and won’t turn on or charge? It’s better not to engage in amateur activities - just take your gadget for repair and report your suspicions about a virus attack. As a rule, your iPhone will be returned to you safe and sound and in working condition. So it's not all that scary. You just have to walk around for some time without your equipment, and also pay a considerable amount of money. But it's better than buying a new gadget.

    Breakdowns

    True, if you are wondering what to do if the iPhone turns off and does not turn on (does not respond to charging), then, frankly, the reason may be that you simply have equipment failures. In particular, this applies to the connectors on the gadget, as well as the charger wire.

    In this situation, frankly speaking, there are several ways out. The first is to try connecting a different charger to your iPhone. A very good option, especially if you have friends with the same smartphone. As a last resort, you can contact specialized salons for inspection. If everything worked out and the iPhone turned on, you can change the “charger”. After this, the problem will go away and will not bother you.

    The second option is when the problem is with the charger connector. If your iPhone 4 suddenly turns off and won’t turn on, you don’t know what to do, then you can completely complain about problems with contacts. Try connecting the charger to the gadget. Doesn't work? Then try it on another iPhone. Did everything work? So, you can safely take your device and take it in for repair. The connector will be quickly repaired there.

    True, they may ask for a fairly large fee for the service. Sometimes it is better to simply change the “tube” rather than repair the old one. But this is not all the options for the development of events. Let's see what else can happen.

    Complete failure

    Here's another rather interesting source of the problem. In cases where the iPhone 4 turns off and won’t turn on, you don’t know what to do; a situation may arise in which your equipment is completely faulty. In other words, it simply broke.

    What should you do if your iPhone turns off and won’t turn on or charge? There are also several alternatives for action here. The first is to take your smartphone for repair. There is no guarantee that it will be fixed, but it's worth a try. Maybe the breakdown is something not particularly serious. Then you will be able to use the gadget again in about 2 weeks.

    The second scenario is a complete replacement of the faulty gadget. So, if the iPhone turns off and won’t turn on - you don’t know what to do, since everything has already been tried, then all that remains is to throw out the old smartphone and replace it with a new one. Which one is entirely your choice.

    In cases where you have not yet expired, you can try to exchange faulty equipment for working ones. True, first you will have to conduct an examination and prove that this situation is not your fault. That is, the problem initially lies in production errors.

    China

    iPhone 4 turned off and won't turn on? Then it makes sense to look at the manufacturer of your gadget. The thing is that quite often this kind of failure occurs due to the fact that you are not holding original equipment in your hands, but a Chinese counterfeit.

    This is what causes most breakdowns. In cases where you decide to use a Chinese iPhone, you should be prepared for the fact that you will have quite a lot of reasons to worry when working with your device. This way, you shouldn't be surprised when a part gets out of control.

    To avoid any problems, it is best to refrain from buying analogues and fakes. It’s better to fork out money once for a good, high-quality smartphone than to later repair something you bought on the cheap. In extreme cases, you should be prepared for trouble. To be honest, it’s better to buy something cheaper, but a real gadget, rather than just a shell. This will reduce the likelihood of problems occurring.

    Thus, as you can see, there are many reasons why an iPhone may turn off and not turn on again. All of them can be solved, although not always without effort. Follow the rules for using your smartphone - this will reduce the likelihood of failures and problems.
