iPhone 7 turns off

Table of Contents

Using a portable battery

A less convenient and aesthetic analogue of a battery cover is a power bank. It works the same way. the iPhone is charged, it heats up and tolerates the cold much easier. The difference from battery cases is that portable batteries are cheaper and have a higher capacity. Many iPhone owners already have a power bank, so they don’t have to spend money to solve the “frosty” issue.

Li-ion batteries in the cold

Lithium-ion batteries have been tested in the United States. According to the results of the research carried out, experts determined that when the temperature indicator drops to 18 degrees, the battery indicator decreases to 50%.

In 2014, Canadian experts conducted an experiment when the iPhone was left in the cold for half an hour. For such a short time, the device did not have time to turn off, but the battery level decreased by 14%. During this time on the device, which was in warmth, the battery was discharged by 1%.

For the battery of the “Apple” gadget, the operating temperature range is from 0 to 35 degrees. In the conditions of practical application of the device, it is quite often difficult to adhere to such conditions. In summer, it is easier not to go beyond this temperature range, but in winter in our realities it is difficult to do this.

Thermal conductivity and thickness of the iPhone case

Many gadgets from other manufacturers can withstand frosts of 30 degrees, and some iPhones will not work for ten minutes at 5 degrees. The main reason for this is the case material. Several recent generations of the iPhone are made of aluminum with a high thermal conductivity (220 W / (m K), which is why it quickly freezes.

For example, the iPhone 4, 4s uses glass with low thermal conductivity (1.15 W / (m.0.20 W / (m K). Therefore, devices in a plastic case are able to withstand very low temperatures.

The thinness of the case is another reason for the problem. The battery starts to work unstable in thin devices faster than in thick ones. All iPhones are thin, so they are not resistant to frost.

Keep your gadget close to your body

To protect iPhone in cold winter, human body heat will be the best protection. Try to keep your phone only in your jacket, in your inner. It is better not to place the device in the of jeans or trousers at all, so as not to increase the chances of a sudden shutdown.

iPhone 11 / X (s / r) / 8/7/6 turns off in cold weather

Let’s understand the reasons why the iPhone turns off in the cold or may reboot. Also in the article you will find some tips on how to solve this problem.

This article applies to all iPhone 11 / XS (r) / X / 8/7/6 and Plus models on iOS 13. Older versions may have different or missing menu items and hardware support specified in the article.

Using the cover

To solve the problem of using the iPhone in winter “with little blood”, you can put your smartphone in a case. The cover itself should not be specially designed or with special protective properties against frost. Any case that covers the phone from all sides will work here. A good option would be a folio case, in which the inside is covered with a soft material.

The ideal option would be a battery case. Using a case that has a built-in battery is a radical way to rid your iPhone of its fear of the cold. Your phone will be constantly connected to a power source, so it will heat up and work without problems in low temperatures. The disadvantage of this method was the high cost of battery covers, but if you cannot do without a properly working device in winter, then this accessory will be a profitable cash investment.

Charging your iPhone in cold weather is not recommended. Before removing the phone from the of your jacket, you should turn off the power. Doing so could damage the iPhone battery.

The reasons why the iPhone turns off in the cold

Many iPhone users are interested in the question, especially in winter, why the device turns off at low temperatures. In such conditions, the battery loses its charge quickly, and the gadget can be completely turned off when the battery indicator level is 20%. Therefore, almost all iPhone owners are trying to figure out why their device turns off in the cold and reacts inadequately to temperatures less than 10 degrees.

Constant exposure to frosty conditions for the batteries of any iPhone is simply destructive. Frequent depletion of the battery will do no good. The battery is one of the most fragile parts of an Apple phone and must be handled with care. A failed battery can always be replaced at the workshop.

If your iPhone turns off frequently, and the device turns off only in the cold, then you need to familiarize yourself in detail with the rules for using the gadget. The screenshot below shows the temperature mode recommended by the iPhone developers.

At low temperatures, the battery cools down greatly, its output voltage decreases. The electronics in the phone start to think that the battery is completely discharged, which turns off the iPhone.

Another weak point of the smartphone was the display. From cold, the matrix may fade and changes on the screen are not displayed so quickly. The sensor starts working with errors, reacts to pressing every time.

Use a different smartphone as a navigator

Many motorists use their iPhone as a navigator. Your car can freeze overnight, causing your iPhone to run out of power quickly. Avoid using it as a navigator in winter. If possible, this work can be provided by an inexpensive Android smartphone, which has a plastic case.

Iphone 7 / Iphone 7 Plus Keeps Restarting Fix. Fliptroniks.com

Car enthusiasts should not leave their iPhone in the car, even for a short time. The smartphone should be connected to the cigarette lighter only with a charger. In such a situation, the iPhone will not turn off.

What to do if the iPhone does not turn on and the Apple hangs

An easy way to solve the problem is to reboot the device using the Home and Power buttons, which must be pressed and held for 10 seconds. If the reboot does not help, then an update or flashing of the device will be required. To do this, run iTunes on your PC.

Step 1: Launch iTunes on your computer and connect the USB cable (you don’t need to connect the USB cable to the phone yet). Turn off the iPhone while holding the HOME POWER buttons (on iPhone 7, you must hold HOME and. Volume)

Hold down the HOME button and connect the USB cable to the device. Hold the HOME button until the iTunes logo and a plug image are displayed on the device screen.

A notification will appear on the computer screen that the device is in recovery mode

Step 4. Now just click on the Restore button. Before restoring your iPhone to factory settings, your computer will need to download the latest version of iOS from Apple’s servers. In this case, the phone will lie with the screen off and show no signs of life. Even with a good fast internet connection, the download process can take 40 minutes or more. If your internet connection is unstable or slow, the process may never complete. Connect to a faster Wi-Fi connection.

The reasons why the Apple burns but the iPhone does not turn on

Before referring to the instructions, you need to understand what caused the iPhone to not turn on and the Apple on the black screen burns. The following reasons are listed:

Sometimes the battery is discharged, the phone is completely discharged, so an Apple appears. Try plugging in your charger and after waiting 20 minutes, try turning your iPhone back on.

The phone freezes when you turn it on, probably a breakdown of the “Power” button. Occurs when disassembling an iPhone.

The device does not boot further than an Apple. a problem with the power supply of the device. This often happens with phones during network jumps when charging.

Charging controller is broken, there was a power outage.

Problems with the power supply circuit of the device. The device lay on the charge during a strong power surge.

Problems with the motherboard, while the phone itself may even boot sometimes and even work for a while. True, the glowing Apple on the iPhone screen will appear more and more often until it stops starting normally at all.

iPhone 6/7/8 / X / 12 won’t turn on lit Apple on and off, how to solve?

Sometimes a glowing Apple on the iPhone screen is on, it hangs and turns off, then the screen will be black, it does not respond to pressing. There are quite a few probable reasons for the appearance of this trouble. Today we’ll look at the most common iPhone won’t turn on problems and try to find a solution.

DFU mode

If your iPhone won’t turn on, even after the one tried above, there remains one more way. restore iPhone in DFU (Device Firmware Update) mode. Follow the link and follow the step-by-step instructions.

There is an easier way to solve this problem, using Tenorshare ReiBoot, one-click you can enter recovery mode and exit recovery mode. Logging in or out can help you solve “the Apple is on but the iPhone won’t start”.

Possible causes of the malfunction

If the iPhone turns on and off immediately, then the reason for this may be:

  • Battery worn out. Its current voltage is simply not enough to initialize the device (it must be at least 2.5V), which is why the device turns off when trying to start the OS. You can check the battery performance yourself only with a digital multimeter (which is also capable of creating a load of 0.5A or more), but for this you need to remove the display module.
  • Software glitch. Most often it occurs due to a lack of free memory on the device (when there is no way to save temporary OS files), as well as due to a “deep” discharge of the battery.
  • Failure of one of the hardware components on the motherboard. When you turn on the iPhone of any version, the first thing to do is initialize the internal components: modem, processor, camera modules, microphone, display. If at least one of them is malfunctioning, then the smartphone retries initialization (reboots). If the error persists, then the phone is completely turned off or displays an error message. In this case, all components may even be serviceable, and the reason is a break in the track on the printed circuit board.

You can try to fix only a software failure on your own, or you can still try to charge the battery. But disassembly in the absence of such experience should not be. In addition, this requires a set of special screwdrivers (Torx T5, ​​T6, Pentalobe 0.8 and so on).

By the way, if the iPhone 6 turns on and off immediately, then this may still indicate that it has outdated software installed. A similar situation arose in 2015, when this model was updated to iPhone 9. Due to a software bug, the operating system often went into a cyclic reboot, which was eliminated only by firmware in DFU mode.

But if the iPhone 5S turns on and off immediately (as well as the iPhone 5 and 5c), then this may still indicate the failure of the Y2 controller (the so-called “quartz”). For these models. a typical breakdown that occurs even due to a slight impact to the lower corner of the case.

IPhone turns on and off immediately: how to restore a smartphone

When performing an iPhone repair, a specialist first of all determines the nature of the breakdown: whether it is software or hardware. In the first case, a banal flashing of the device (reinstalling the software) helps, in the second, you cannot do without disassembling the gadget and a detailed examination of the motherboard. And if the iPhone turns on and off immediately, then this can occur both with software and hardware failures. What can the user do in this case before contacting the service center.

What to do

The first step is to put the phone on charge and leave it for 30. 60 minutes (even if it does not show any signs). After. try to turn it on in the usual way. If there is no reaction and the backlight does not even come on, then this is a clear problem with the power supply. That is, the hardware room. then you should contact the service center. You can replace the battery on your own, but it’s not a fact that the problem is with it. It is possible that the power controller has 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 immediately while charging, that is, during boot (the display shows the Apple logo. an Apple), this is most likely a software failure. To fix it, you need to do a full reset of the device in the following way:

  • update iTunes on PC to the latest up-to-date version (only MacOS and Windows are suitable, iTunes does not exist for Linux distributions);
  • using a USB cable, connect your smartphone to a computer (preferably to a USB 2.0 port located on the back of the system unit);
  • if the phone is recognized in iTunes (an image of a USB connection will appear on the iPhone display), then you need to select “Restore iPhone” in the application and follow the prompts on the screen to reset, the firmware itself will be downloaded automatically;
  • if after connecting the iPhone to the PC nothing happens. press the Home and Power keys on the smartphone at the same time and hold them for 10 seconds, then release Power, but leave the Home key pressed, waiting for the drivers to be installed, then select “Restore iPhone” in iTunes “And wait for its flashing.

Attention! The Home Power combination is putting the phone into the so-called “Recovery Mode” (DFU). It is used to update the software or to reinstall it in cases where the smartphone does not work properly due to a software failure.

For iPhone X and other phones that do not have a physical Home button, enter DFU mode by holding down the Power and Volume- keys. In the same way: hold down for 10 seconds, then release Power and continue to hold the Volume- key until the computer recognizes the device (the iPhone detection dialog box appears in recovery mode).

If all else fails

If the above tips do not help restore the iPhone’s functionality, then further repairs are possible only at a service center. The most common failures that cause cyclic reboots are as follows:

  • malfunction of the battery power controller or on the motherboard;
  • malfunction of the processor chip;
  • short circuit of the power supply circuits of the display module (this happens when moisture gets inside the case);
  • faulty modem (controller of wireless networks).

In each of these cases, the faulty part is simply soldered out and replaced with a known good one.

And in order to avoid such problems in the future, you should adhere to the following rules:

  • use only the original charger;
  • do not install non-original rechargeable batteries in the phone;
  • if you suspect that moisture has entered the body, immediately turn off the phone and contact the service center;
  • perform a full reset of the phone at least once every 6 months (the backup data will be saved in iCloud or you can make a copy via iTunes).

Bottom line, why does the iPhone turn on and off immediately? often. due to a software failure or failure of the battery. If the smartphone has not fallen or bathed before, there are no traces of mechanical damage on the case, then you can try to reflash it yourself via iTunes (in normal and DFU mode). If this did not help or reset the software did not work at all, then you cannot do without detailed diagnostics in the service center.

iPhone turns off in the cold: why and what to do?

Formally, winter lasts only 3 months, but in fact, even in central Russia, it can be delayed for a month or two. With the onset of winter, problems arise, and often they appear, as it might seem, out of nowhere. For example, in the cold, your favorite iPhone simply turns off. Why is this happening, what to do and what other troubles are worth waiting for? All this is in our article.

Why does the iPhone turn off in the cold?

IPhone smartphones use lithium-ion polymer batteries (Li-Pol). In essence, these are advanced lithium-ion batteries that are endowed with a higher energy density per unit volume and mass. However, such batteries also have disadvantages: at temperatures below 5 ° C, they can lose some of their properties, as a result of which the internal resistance increases, the capacity decreases, the batteries are not able to deliver the declared current, as a result of which the smartphone can simply be taken and turned off. Interestingly, the manufacturer itself does not prohibit using the iPhone in the cold, moreover, it would be, to put it mildly, strange.

Note that modern models like iPhone 6, 6s, 7, 7 Plus, etc. turn off in the cold much less often. Models that have been in operation for a long time are most susceptible to this: batteries have a limited number of operating cycles and after crossing a certain threshold, they begin to rapidly lose their properties.

If your iPhone turned off in the cold, most likely nothing terrible happened and it turned off precisely because of the subzero temperature.

What to do if iPhone turns off in cold weather?

The first thing you need to do is try to turn on your iPhone. If it does not respond to pressing the Power key, you need to go into the room and wait 20-30 minutes until the device “warms up” to room temperature. After that try to enable it.

If even after an hour or two of being indoors, the iPhone does not want to turn on, you need to put it on charge. Please note that in this case, the charging time of the smartphone may significantly increase. up to several hours.

If all else fails, contact the service center.

What other problems arise with the iPhone in the cold?

Shutdown in the cold is not the only problem that can await an iPhone user. What else?

  • First, a faster battery discharge. This, again, is directly related to the Li-Pol technology. However, we note that the problem of a faster discharge of the gadget in the cold is relevant for almost all devices with batteries.
  • Secondly, in the cold, the iPhone touch screen may stop responding to pressing. Imagine trying to click on an application icon and nothing happens. You should not sound the alarm, try to enter the room and after a while the sensor should work.

How to protect your iPhone from the cold?

There is no perfect solution, but we will give you some tips that can help keep your smartphone fully functional.

  • Try to keep the gadget in the cold as little as possible. For example, talk to a friend and immediately put your iPhone in your. Or even use a headset for communication.
  • Keep your phone in your. which is closest to your body. it’s warmest there. Or use the inside of your jacket or down jacket.

A cover can be purchased. The cover saves the smartphone not only from scratches or drops, but also from the cold. Of course, the cover will not be able to completely protect from frost in any case.

Why do many other smartphones work without problems in winter

Many smartphones from other manufacturers can easily withstand 30-degree frosts, what is the problem with iPhones, which cannot work for ten minutes at.5 ° C? The first reason is the materials of the case. Aluminum, from which the cases of several recent generations of iPhone are made, has a high thermal conductivity (220 W / (m has a high thermal conductivity (1.15 W / (m K), however, this is enough for the smartphone to freeze and start working incorrectly, or turn off.

The second reason is the thinness of the iPhone cases. In thin smartphones, the battery becomes unstable much faster than in thick ones. Considering that almost no iPhone can be called “fat”, we get a high instability of Apple smartphones to frost.

Why the iPhone behaves so badly in the cold

First, let’s figure out why, in fact, the iPhone starts to work inadequately or turns off altogether in the cold. There is no secret here, the culprit is the lithium-ion batteries of Apple smartphones. At temperatures below 0 ° C (and in practice even below 5 ° C), battery ions begin to lose their properties. As a result, the internal resistance rises and the capacitance is lost.

Due to the loss of capacity, fortunately, only temporary, at subzero temperatures, the iPhone can turn off, while still having a large percentage of the charge left. Lithium-ion batteries no longer provide the current necessary for the smartphone to work, and the iPhone simply physically cannot continue to work.

Charge iPhone up to 100% before going outside

The more charge your iPhone has, the longer it will last in freezing temperatures. Ideally, iPhone should be charged to 100% before going outdoors so that even if the battery is severely discharged due to cold, the battery still has resources.

Which iPhones suffer the most in the cold

But why, then, one iPhone with 50% of the charge works quietly in the cold, while the other with 70-80% turns off in the same conditions? The fact is that lithium-ion batteries have a limited number of operating cycles, after overcoming which their capacity decreases. For an average iPhone, the number of such cycles is about 800-900. With active use of a smartphone, the “critical” moment comes after two or two and a half years of using the device.

The conclusion from this is simple. old iPhones that have been in operation for two years or longer suffer the most in the cold. That is why inquiries about how to normally use the iPhone in winter in Russia are so popular, because we have old, but still quite combat-ready models of Apple smartphones in use.

A detailed guide on how to determine the number of iPhone battery recharge cycles is available here. And this manual describes a method that allows you to do this without using a computer.

Use a case

The solution to the problem of using the iPhone in winter “with little blood”. putting the smartphone in a case. The cover does not have to be special, with some kind of special frost protection. Any case that covers the smartphone from all sides will do. An excellent option is a folio case, the inner side of which is covered with any soft material.

The ideal option is a battery case. Using a case with a built-in battery is a radical way to rid your iPhone of your fear of the cold. Your smartphone will be constantly connected to a power source, which will heat up and work without problems at low temperatures. The disadvantage of this method is the high cost of battery cases, but if in winter, because of work or for any other reason, you cannot do without a properly functioning smartphone, the accessory will be an excellent investment.

Important! We warn you that it is not recommended to charge your iPhone in cold weather. Turn off the power before removing your smartphone, for example, from a jacket ! Otherwise, you could damage the iPhone battery.

Keep iPhone as close to your body as possible

Body heat is the best protection for your iPhone in cold winters. Try to keep your smartphone in the inner of your jacket, and not out of habit in the side. It is better not to place the iPhone in the s of trousers or jeans at all, the chances of a sudden shutdown will only increase.

Warm up your iPhone with a demanding game or application

If you know that your iPhone should be out in the cold for the next 20-30 minutes, for example, you are taking pictures or having an important conversation on the phone, use an effective “folk” method of countering the cold. Launch a resource-intensive game or application on your smartphone. The processor is activated, the iPhone will begin to heat up and function quietly in sub-zero temperatures.

iPhone turns on and off while charging. how to make it work?

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 has in mind. And recently I faced this problem personally, so the picture is right in front of 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 was nothing criminal. put it on charge and went about his business.

I come back after a while, and I see a very strange and inappropriate behavior of the device. the iPhone turns on, the screen lights up for a while (an Apple appears and even a glimpse of entering the password is visible) and immediately the display goes out and the phone turns off safely. And that’s it, it happens all the time. For the sake of the experiment, I waited another 20 minutes. nothing has changed (it just got hot), and I continued to switch 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 the service center, and in a fairly easy way.

But first, about how to prevent such a situation and what you should pay attention to:

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

Actually, almost all of 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 almost as it should), only the wire and charging are originals.

When connected to a charger, it turns out that:

  • All incoming energy is spent exclusively on system loading and display backlighting.
  • This energy is lacking.
  • She cannot accumulate.
  • iPhone seems to turn on, but immediately discharges and turns off.
  • And then it’s all over again.

From which we definitely need to find a way out.

  • Use a more powerful power adapter. The one that comes with the iPhone produces 1 amp and is clearly not enough in such a situation. So you need something stronger, for example, from the iPad. It has 2.1 amperes of output and is capable of delivering more power, which is enough to turn on. Is it safe? Apple says you can do this, and there is no point in not believing it.
  • In the case when there is no other adapter at hand, it is necessary to perform the following operation. enter the device into DFU-mode 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 there will be no energy consumption and all of it will go to charge the battery. After 20-30 minutes, turn on the iPhone and are glad that the shutdowns have stopped.
  • This method 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 recharge the battery in such small portions to the state that is enough to fully launch the iPhone.

Finally, I would like to note that the situation considered in this article, of course, is not normal and in an amicable way, the battery must be changed so that there are no other surprises in the future.

But. my job is to give advice, and you already decide for yourself. is it worth running for a new battery or “it will do just that”!

Why iPhone turns off and what to do about it

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

  • a problem with the indicator. the device shows incorrect data on the state of charge of the battery and, for example, at 50 battery charge, in fact, the device is 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
  • a problem with the device software. in order to fix this problem, you should return to the factory settings. perform a 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 dealt with 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 you turn off the Apple technology

To troubleshoot the software, launch iTunes and connect your smartphone to your computer, back up your 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.

Keep in mind that at low temperatures, a charged battery on any iPhone model will drain faster than in warm temperatures. Low temperatures do not affect the battery capacity in any way, but so that it is not discharged at the wrong time and does not sit down too quickly, you can put on a special case and carry the phone in the inner of your jacket. In cold weather, it is recommended to avoid photography and other heavy loads. In such a situation, the phone can suddenly sit down at 80 percent, half and 30 percent of the charge.

If your device can unexpectedly turn off at almost full or half charge, it charges too slowly and not completely, perhaps the problem is that you are using not the original charger, but a low-quality analogue. In this case, all you need to do is replace the charger with a suitable one.

Other signs of breakage

The fact that your iPhone shuts down at 20 percent may not be the only symptom of a breakdown. Other common problems are listed below:

  • iPhone turns off when taking photos even though it is more than half charged
  • the phone charges up to 3 percent or 1 percent and turns off
  • the smartphone turns off by itself when fully charged
  • iPhone shuts down and shows blue screen
  • the phone sits down too quickly (may shut down at 70 percent, 60 percent, or 35 percent)
  • when charging is connected, the battery does not charge or only charges up to the middle
  • the phone spontaneously goes into standby mode at high loads or even in their absence

Most likely, when such signs appear, it will not be possible to fix the breakdown on your own, and you still have to seek the help of qualified specialists.

And get the best deals from trusted masters.

  • Compare and choose the best conditions
  • Feedback from interested professionals only
  • Don’t waste time communicating with intermediaries

Often, the owners of expensive Apple technology are faced with the fact that the iPhone turns off at 20 percent. If you are familiar with such an unpleasant problem, 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 fixed on their own and quickly enough.

When to contact a specialist

If you’ve tried all of the above methods and your iPhone still shuts down at 40 percent, 15 percent, or 10 percent, you should go to a professional like Yuda. Perhaps the reasons why iPhones turn off are much more serious, and they do not relate to software, but to the “stuffing” of the iPhone. This could be:

  • battery breakdown
  • loop break
  • microcracks on the board
  • connector malfunction
  • other hardware malfunctions
iphone, turns

Experienced craftsmen registered in Yuda will diagnose and accurately identify the cause of the breakdown. Using special tools and original spare parts, they will carry out all the necessary work. supply a new battery, repair the connector, replace the ribbon cable, etc. Upon completion of the work, you will receive a working device that will serve you for a long time. The wizard will provide you with a guarantee for all work performed and give advice on handling the phone.

Contact Yudu’s specialists if your iPhone turns off at 20 percent. whatever the phone model and whatever the cause of the breakdown, the experts will repair the iPhone efficiently, inexpensively and in a short time.

Battery low

The most common reason for a device shutdown is a low battery. All you need to do is put the phone on charge and press the power button. If he sat down completely, he will be able to turn on only after 20-30 minutes.

From time to time it happens that the phone shows a normal battery charge, but in fact, the device has been requiring charging for a long time and may suddenly turn off completely. This does not mean that you need to replace the battery, the battery indicator may not be working properly. This problem can be dealt with by a hard reboot (discussed below).

Also, if your device can completely turn off outside in cold weather, this is an unpleasant, but completely normal phenomenon. Again, you don’t need to replace the battery, it’s just that in freezing temperatures outside, it’s best to carry your iPhone in the inner of your jacket and put a case on it.

iPhone turns itself off

And get the best deals from trusted masters.

  • Compare and choose the best conditions
  • Feedback from interested professionals only
  • Don’t waste time communicating with intermediaries

If your iPhone turns itself off for unknown reasons after a conversation, when the camera is turned on, or constantly, this can bring a lot of inconvenience: you will not be able to take an important call on time, use the Internet or perform other necessary manipulations with the device.

To cope with this problem, you do not always need to contact a specialist. You can try to restore the correct operation of the smartphone yourself. it will stop suddenly going out and will react to the power button. The reasons why the iPhone turns off can be of two types:

  • software problems
  • problems with the “stuffing” of the iPhone

If your iPhone turns off due to software problems, it is quite possible to deal with this on your own.

Software malfunction

Your iPhone may be shutting down after installing programs that are causing system errors. There are two ways to deal with this problem:

  • first of all, you should carry out a hard reset (press the “Power” button and the “Home” button at the same time and wait about 15 seconds until the “Apple” appears). After that, the phone will work correctly again.
  • If pressing the Power button and Home button did not help, you should try to restore your iPhone. Recovering your device. resetting the operating system is easy. enter the iOS menu and select “reset all settings”. When restoring a device, data on it is not lost, but it is best to make a backup

If these methods did not help, perhaps the reason for the shutdown is not in the installation of programs, but in the hardware of the iPhone. And in this case, you should already contact the master.

Other malfunctions

Your iPhone turning off by itself may not be the only symptom. In addition, other problems may occur:

  • the device turns off when the camera is turned on
  • the backlight turns off after a call
  • the sound is turned off
  • iPhone requires charging even though the battery is full
  • iPhone does not work at all and shows a blue screen

Help from specialists

If you have done your best to ensure that your iPhone stops constantly disconnecting after a call or at any other time, you need to turn to professional specialists such as Yuda performers. Masters registered to Yuda know exactly why iPhones turn off and what to do about it. You can be sure of the following:

  • only original spare parts will be used with your iPhone
  • during the repair, special tools will be used
  • iPhone repairs will be performed by experienced craftsmen with the necessary licenses

With any type of breakdown (iPhone often turns off, its battery is broken, the sound does not work, or the backlight turns off unexpectedly), the masters registered on Yuda will cope as quickly as possible. They will carry out diagnostics to understand why the iPhone turns off by itself, and will replace the necessary parts.

Discharge the battery to zero and then fully charge

If the problem is related to the indication of the battery charge level (say, the battery statistics are not registered in the system in the correct way), then the solution may be the procedure for discharging the battery to 0% (until the device itself turns off due to lack of power) and then charging it to 100 %.

Recovery via iTunes

One of the last remedies may be to restore the device to a new state with factory settings through the iTunes application.

Step 1: Connect your iPhone to your Mac / PC and launch iTunes.

Step 2: After recognizing your iPhone in the app, select the device bookmark and select “Back up now” to create a local backup of your device.

Step 3: After completing the backup, click on “Restore iPhone.”. After that, the process of downloading the latest version of iOS software will begin, completely deleting data and installing a new operating system on your device.

At the end of this procedure, your phone will be restored to the state when it first came into your hands. After that, you will be prompted to restore your phone data from the previously saved backup. After the data recovery process, all your applications and their data will again appear on your iPhone.

The first time users reported this problem when iOS 9 was released. The problem was random and the pattern of its occurrence was not clarified.

But users reported that updating to the latest version usually resolved this issue for them. At the time, it was iOS 9. At the time of this writing, this is iOS 10.1.

Therefore, after launching and with the iPhone running (preferably after performing a hard reboot procedure), go to “Settings”. “Basic”. “Update software” and update to the latest OS version.

Does your iPhone or iPad shut down unexpectedly even when charged? Here’s how to fix it

If your iPhone is behaving strangely: it turns off by itself, even with the remaining charge at 15% or 30%, then you should know that this is not news and you are not the only one faced with a similar problem. Users have reported this problem all over the place since the release of iOS 9. And even now, in 2016, many of us still face this problem.
If your iPhone suddenly shuts down even when there is sufficient battery power, try the following suggestions to fix the problem:

Check if you have the latest version of iOS?

Charge your device

If your device is unresponsive and nothing works (not even a hard reset), just put your phone in the charger and leave it there for an hour or so.

If that doesn’t work, try a different cable or charger, or try charging with your Mac.

Perform a hard reboot

Usually a hard reboot will fix this problem. A hard reboot is similar to “did you try to turn 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 up to iPhone 7), hold down both the Power and Home buttons for 5 seconds. The iPhone will restart, you will see the flashing Apple logo icon and the iPhone will come to life.

On iPhone 7 and iPhone 7 Plus, hold down the Power and Volume Down buttons to perform a hard reset.

Contact Apple

If you have done all the above procedures, then we have eliminated all possible reasons for the sudden shutdown of your iPhone even with a sufficient charge level at the software level.

This is all we can do ourselves. Your device may have a damaged battery or other internal electronic component. If your iPhone is about 3 years old or more than 4 years old, then it probably is (I’ve even seen an iPhone 6 with similar defects).

In such a case, the best thing to do is to call Support or visit your nearest Apple support or Apple store. If your device is still under warranty or has an extended warranty from Apple Care (always a good idea), then Apple can swap your device for a new one, or you will pay to have your device repaired.

iPhone won’t turn on after being dropped

The absence of external signs of breakage (chips, cracks on the screen or case) does not mean that the fall went without consequences. Internal damage to the backlight layer of the screen, connector pins or mounts occurs at least often. So in the event that the iphone 6 does not charge and does not turn on immediately after a fall or a strong blow, then it is better to go straight to the service center to fully diagnose the device.

Frostbite of the apparatus

It is known that Apple smartphones are sensitive to cold, refusing to work sometimes even in minimal frost. At temperatures close to zero, the internal resistance of the lithium-ion battery rises and capacity is temporarily lost. Slim iPhone cases are made of aluminum, which has more thermal conductivity than plastic. Therefore, plastic smartphones of other companies with the same type of batteries withstand the cold much better.

If the smartphone is “frozen”, then in most cases warming up the device will help. Place your phone in a warm, dry place and connect the charger to it. Depending on the degree of “frostbite”, it will take up to 15. 20 minutes for the phone to be in such conditions. If the device does not come to life after the specified time, then try turning it on by pressing the power button or “hard” rebooting.

How to Reset iPhone 6 / 6S If It Won’t Turn On

A full factory reset erases all information and only installs the original firmware. So, if you do not take care of the timely backup, all data will be lost.

To do a factory reset, you need a computer with iTunes and an original USB cable. The sequence of actions is as follows:

  • Connect iPhone to Computer with Original USB Cable.
  • Wait for the program to recognize the device.
  • In the main window of phone settings, find the button “Restore iPhone.”.
  • Confirm the action and wait until the end of the procedure. iTunes will restart the smartphone after the restoration is complete.

IPhone 6 / 6S software bugs

The consequences of software failures are the easiest to eliminate. When an application or the operating system itself hangs, in most cases a hard reboot helps. Hold down the power and Home buttons for 15. 20 seconds. Do not release the keys after turning off the smartphone, but continue to hold until the Apple logo appears and iOS starts loading. If the reboot did not help and the phone does not turn on or hangs during the boot phase, then recover from the backup. A detailed description of the procedure is given at the end of the article.

Jailbreak issues

6th iPhone hardware issues

The “hardware” of a smartphone can break even without good reason in the form of a blow or a fall. just because of age. The contacts are gradually thinning and breaking off, the loops are frayed. The humid air gradually “burns out” the conductive tracks on the motherboard. It can take a long time to list the internal elements and possible options for their failure. There is only one verdict. they can only diagnose and establish why the iPhone 6 does not turn on in a service center.
