How to turn on iPhone 5s if it won't turn on? Solution similar problem will be discussed below.

Causes and solutions

Causes of malfunctionthere can be many, but the most common:

Problems with the power controller

The power controller is an element that is responsible for charging and correct operation device batteries. The cause of failure may be a low-quality charger (cheap Chinese fake original iPhone charger), dropping the phone, getting water inside.

The most interesting thing is that the failure of the power controller can be similar in symptoms to a battery failure, so many people buy new battery. Imagine their surprise when the phone does not work even with a new battery! So, before doing anything, we strongly advise you to take the device to a service center, where they will determine the exact cause of the breakdown.

If the controller does break down, it needs to be carefully re-soldered. It’s better not to try on your own; you might damage the board, and it’s not cheap, especially for the iPhone 5s.

Water ingress

If you manage to drop your phone in water or some other liquid, experts recommend immediately putting the smartphone in a plastic bag or container, and then transferring the container with the phone to the nearest service center as quickly as possible. If the gadget stops turning on after getting wet, then the chances of it being repaired are minimal.

If there is no service center nearby, then do the following:

1. immediately turn off the phone and take it to the service center without turning it on;
2. check the moisture indicator. It is located in the headphone jack. If water gets inside, the color of the indicator will change from white to red;
3. If you notice that the indicators are red, immediately remove the battery from the phone. To do everything correctly, we recommend watching training videos from professionals on the Internet.

If everything is done on time and correctly, then the chances of restoring your favorite phone increase significantly.

It is worth saying that after the water it will no longer be possible to profitably resell the phone, except to an ignorant person.

Voltage drops

Apple technology is very demanding on the quality of the incoming current, so their charging device made in a special way, have a complex design and operating principle. If you charge it with a non-original device, then even a small voltage surge can damage your smartphone.

When the voltage drops, the power controller mentioned above suffers. It can be replaced, the cost, thank God, is small, but an unpleasant aftertaste remains, and you don’t want to part with your favorite gadget for a long time.

The battery is old

A failed battery is another reason why the iPhone 5s won’t turn on. This happens rarely so far, since the phone went on sale relatively recently, but the further, the more often phone owners are faced with this problem. There is only one way out - replace the battery, you can’t do anything with it.

Photo: original iPhone 5s battery

We recommend buying a new battery exclusively from a licensed Apple service center, this way you can insure yourself against buying a counterfeit. Before purchasing, be sure to take your phone for diagnostics to determine whether the problem is really in the battery. In official service centers, diagnostics are free.

If the battery, after charging, holds a charge less and less, and one day the device simply does not turn on, then the problem is 99% in the battery.

iPhone 5s won't turn on

There can be many reasons why the phone won’t turn on, and all of them relate not only to our today’s hero, the iPhone 5S.

Won't turn on due to broken charging connector

If the phone is discharged and does not turn on when charging, or does not react at all to connecting the cable, then most likely there is a problem with the socket. It breaks very rarely, but it gets clogged all the time. Those who just bought an iPhone 5S have not yet encountered this problem, but there is still more to come.

The connector becomes heavily clogged with dirt, fluff, and other debris, as a result of which the clogs block the charging and connector contacts and they no longer touch.

Photo: example of how the charging cable connector can be dirty

You can also clean the connector with a regular toothpick, but it is not advisable; if you are careless, you can damage the contacts, and then you will have to replace the connector altogether, and this is already a considerable amount of money.

Much would be better suited a can of compressed air, but due to the fact that you only need to clean one phone, no one will buy it, except perhaps service centers. By the way, some service centers can clean the sockets with compressed air for a thank you; they value regular customers and want to have more of them.

It is also worth noting that if you charge with a non-original charger, it can deform the socket, after which standard charging will not work correctly.

After car charging

The problem is that some people don’t know how to choose the right car charger for their iPhone. People are trying to save money, so they buy the cheapest options, which are not always of at least average quality.

After using a low-quality charger, the following may fail:

1. battery;
2. charging connector;
3. power controller;
4. specific power supply circuit.

As you can see, small savings on a charger can result in a decent amount of repairs.

If the phone stops turning on after using a low-quality car charging, there is nothing left to do but take it to the service center. There is no point in trying to determine the breakdown yourself, or, moreover, to repair the smartphone, since with inexperienced hands you can render the phone unusable.

After the firmware

iPhone is a very complex piece of technology; we do not recommend reflashing it yourself under any circumstances. If you make even a small mistake, you could end up with a phone that never rings again, or that never turns on again.

There are a lot of reasons why the iPhone 5S does not turn on after flashing, but the most common are three:

1. The Nor Flash chip is broken. She is responsible for normal work GSM module. Without this chip, the smartphone will not make calls, since the settings of all operators in the country are saved in it. The problem is solved by replacing the microcircuit at a service center;
2. The NAND Flash chip has failed. She is responsible for the safety of personal data, that is, programs, notes, contacts, photos, music, and so on. Solved as previous problem, replacing the microcircuit at a service center.
3. Wrong installed firmware. Take your phone to an official service center and have them install a normal, working and stable version of iOS.

Unsuccessful updates can also be attributed to this section.

After the fall

If your phone does not turn on after being dropped from a great height, take it to a specialist. There is no way to do this without diagnostics. If external damage does not have such a strong impact on operation, then internal damage is quite capable of completely destroying the phone.

The most popular internal breakdowns during iPhone falling 5S:

1. damage printed circuit board;
2. disconnection or damage to the cable.

In the first case, you cannot do without a specialist. Repairing a printed circuit board is very complicated; it is almost impossible for an ignorant person to get the necessary parts. As for the cable, it is enough to order an analogue of the damaged one and replace it. There is nothing complicated, you don’t even need to solder anything. In some cases, you can just put it in place and everything will work.

The most important thing is to watch the relevant master classes on the Internet before disassembling the phone, otherwise some elements may be seriously damaged.

After replacing the display

If the display is changed at a service center, then everything should be fine, but if you change it at home, on your own and without much experience working with Apple phones, then a problem can await you at any second. Something is slightly caught, and that’s it; when you try to turn it on, a “surprise” may await you.

iPhone 5s won't turn on, apple lights up

If, when you turn on your smartphone, it gives you the branded “apple” and does not want to boot further, this means only one thing – the firmware has failed. It is worth noting that in this case all your personal data from the phone will be lost. To prevent this from happening in the future, we advise you to constantly update backups. If the apple is on fire, your data is lost. This is to put it briefly.

There is only one solution - take it to a service center to restore the firmware.

In conclusion, I would like to say that no matter what problem happens to your favorite iPhone 5s, immediately take it to the service center! Do not try to fix the problem yourself, otherwise there is a high chance that you will have to buy a new phone.

Even if the breakdown seems insignificant, you should not take the risk, because the amount you plan to save may increase significantly to eliminate the breakdown after your repair.

On average, service life battery iPhone 1.5-2 years. It happens that after 2-3 years the iPhone battery continues to serve faithfully, but it happens that after a year the battery begins to noticeably heat up and has to be charged more often. How do you know when it’s time to change? battery iphone and what can happen to the iPhone if this is not done in time...

When it's time to change the battery on your iPhone, it's not difficult to figure out. By this time, the battery has lost a significant part of its capacity and life. battery life iPhones are shrinking sharply. At the same time, the iPhone case gets very hot when surfing the Internet and telephone conversations. In the cold, an iPhone with a “dead” battery may turn off spontaneously due to a sharp drop in charge level. Naturally, all these symptoms do not add joy to our lives and it’s time to contact a service center to replace the iPhone battery.

But something always prevents us from doing this. Either there is no time, then there is no money... Meanwhile, the iPhone battery turns into a time bomb. Yes, exactly a bomb, since chemical processes occur inside the battery. If the battery is not replaced in time, it will gradually swell. Here, admire it

Sometimes we have to remove such batteries from iPhones. And there are even more complicated situations, when a swollen battery squeezes out the display iPhone module, and it’s good if the display remains intact and is not damaged, otherwise you have to change the display module.

The worst thing that can happen to a swollen battery is it catches fire and explodes! Of course, after such a “terrorist attack” the iPhone will be left with horns and legs, and its owner may end up in the hospital with at least burns!

As you can see, there is no point in delaying a visit to the service center to replace a battery that has exhausted its life. Moreover, the replacement process will take very little time, and we usually replace the battery on an iPhone within a few minutes in front of the client.

Let's look at how the battery in iPhones changes. For example, in iPhone 5S

iPhones, starting with the fifth model, are disassembled through the display module. That is, they do not have a back cover, and to get inside the iPhone 5S we need to remove the display. To do this, unscrew the 2 bottom screws

Using a suction cup and a plastic spatula, carefully remove the lower part of the display module from the housing. There is no need to make any effort here and there is no need to rush either! We only need to open the iPhone case slightly to disconnect the cable Home buttons from the bottom loop. If you do not calculate with effort, you can easily break the train and then Touch function ID will stop working forever!

First you need to remove the metal plug, and then disconnect the Home button cable connector from the bottom cable.

Once the Home button cable is disconnected, you can lift the display module completely and lock it at a 90-degree angle

Now we need to unscrew the 2 screws that secure the battery connector plug

Remove the metal plug from the battery connector.

The sacred rule of the engineer of our service center "Remont48" is that the first thing you need to do is turn off the power to the device! No matter what we are going to do inside the iPhone, we first need to disconnect the battery connector from the system board, thereby preventing spontaneous switching on iPhone while disconnecting or connecting cables. This may cause the system board to burn out!

Disconnect the battery connector from the iPhone system board

We unscrew the 4 screws that secure the plug for the display module cables. These screws are all different lengths, and under no circumstances should they be mixed up! If you tighten a screw that is a little too long in the wrong place, you can cut off the conductors on the system board and the iPhone will partially or completely stop working!

Remove the metal plug. After replacing the battery on your iPhone, be sure to replace all metal plugs! Private self-taught craftsmen, unscrupulous, basement “service centers” often neglect this and do not put the plugs in place. And with the slightest impact or fall of the iPhone, the connectors fly out of the connectors. A person thinks that the iPhone is broken, again turns to these crooks, and they, simply inserting the cable into place, pass it off as serious damage! This is another reason to contact only trusted service centers!

Unfasten the display strap, touchscreen, front camera, light sensor, proximity sensor and conversational dynamics plastic spatula.

The display module has been removed.

We put it to the side and heat the iPhone case on the separator so that the tape that secures the battery to the case softens.

Pull out 2 strips of double-sided tape from under the battery

Use a wide plastic spatula to pry up the battery and remove it from iPhone cases. This must be done carefully so as not to damage the cable of the volume buttons, vibration switch and power button!

N The new battery must be glued to the iPhone case with double-sided tape and everything must be screwed and installed in the reverse order.

We looked at the simplest case of replacing the battery on an iPhone 5s, when the battery itself is not swollen. When the battery is swollen, you need to be extremely careful and careful not to tear its casing. When replacing a swollen battery, wear safety glasses and gloves. Otherwise, it may explode during peeling, damaging the hands, face and eyes of the master!

As you can see, replacing the battery in an iPhone is not as easy as it seems. Therefore, it is better to entrust such work to qualified specialists who are not the first to encounter similar work and they know all the intricacies of their business! Never trust the battery to be replaced iPhone first to an oncoming “master” or a self-taught acquaintance. Not only that, due to inexperience, he can damage the cable or system board iPhone, it will also install a fake one for you Chinese battery, of which there are now a lot on free sale! Can you imagine the danger of a fake battery?! Typically, such batteries have a short service life and almost always swell. You understand, it’s not far from an explosion!

We wish your iPhone battery to last a long time and delight you with its supply of positive energy! But if he suddenly asks for a well-deserved rest, then we will send him into retirement without any problems, and in return we will supply an original and high-quality one, for which we will give a guarantee!

Many mobile phone owners sometimes face the problem of their devices suddenly turning off. This problem has not spared the products either. Apple. So, what to do when your iPhone won't turn on?

Possible causes and solutions to the problem

In such a situation, the first thing we recommend is to connect the charger supplied with the phone to the phone. This will make it possible to find out what condition the phone's battery is in. If the battery is working properly, then after some time after connecting to electrical network The iPhone will begin charging, and the user will see a corresponding image on the screen. If the battery is very low, you need to wait about 15 minutes and then try to turn on the phone by pressing the HOME button at the bottom of the device or the On/Off button. at the top of the device.

If these actions do not produce results and the phone does not turn on, you should simultaneously press and hold both buttons: “HOME” and power. If the phone starts to boot, the Apple logo in the form of an apple will appear on the screen. Then the buttons can be released. After this, the device's operating system should boot completely. Otherwise, the logo will remain on the screen. In such a situation, you can try to restart the phone again by first turning it off and then turning it on using both buttons. If such actions do not produce any results, the cause of the malfunction probably lies in something else.

iPhone won't turn on due to broken charger port

Why might my iPhone not turn on? What to do in such a situation? One of the reasons that the iPhone does not turn on may be a failure of the charger connector. This often happens if you carry your phone in your trouser pocket and do not clean the device’s body. If this happens, the charging port may become clogged with dust and debris and may no longer function properly. In addition, there are often cases when the socket for connecting the charger breaks when you try to insert the plug into it the wrong way.

In any case, if the iPhone stops turning on after charging the device in the car, you must definitely take it to a service center. It will not be possible to solve such a problem on your own without special tools and skills.

iPhone won't turn on after restoring or updating

Many iPhone 4S/4S users wonder why the phone sometimes turns off after trying to install new firmware on the device. Often during this process the phone turns off and can no longer be turned on in the traditional way. As a rule, there are two reasons for this behavior of the iPhone. Firstly, the microcircuit may fail GSM module called Nor Flash. This element of the phone has the important function of setting up the device for SIM cards of cellular operators. If during the firmware process there is a failure in the operation of this module, the phone will turn off, and then, even if it turns on, it will not be able to make voice calls.

Secondly, the NAND Flash chip may fail. This element of the phone is used to store all user information. This includes photos, videos, phone book entries, installed applications, etc. It should be emphasized that iPhone 4S and 5S do not have the function of installing an additional memory card. Therefore, if the NAND Flash fails or does not work correctly after flashing, the phone will not turn on until the problem is fixed. It should be emphasized separately that there is no need to panic in such situations. This problem can be resolved by re-flashing the device.

iPhone won't turn on after falling from a height

If dropped from a significant height onto a hard surface, the iPhone 4S/5S may become damaged, turn off and not turn on again. Why is this happening? There are several common reasons for this device behavior. Firstly, as a result of the phone falling, one or more cables could become disconnected. This leads to loss of functionality of the battery, screen, on/off button and other iPhone mechanisms. A very strong impact may damage the components of the device’s motherboard or break the device’s microcircuit. If such damage occurs, it is not recommended to try to disassemble the phone yourself and identify the malfunction. It would be better to take it to a service center and entrust the repair of the device to professionals.

iPhone stopped turning on after getting wet

If the iPhone 4S/5S turned off and stopped turning on after being exposed to rain, water obviously got into it. In this case, just a couple of drops are enough for the device to temporarily fail. Thus, moisture can get inside through the phone connectors. It is recommended to send such devices to official service centers for repair. It is not advisable to do such work yourself. Although, you can try to open the device yourself and let it dry properly. Be sure to disconnect your phone battery.

You can dry your phone using a household hair dryer. With careful airflow and enough time for the procedure, there is a chance that the phone will work again. Otherwise, it is not possible to identify the reason for the iPhone’s refusal to turn on at home. Then you need to use the services of specialists at the service center.

iPhone shows apple logo and does not start the system

This behavior of the iPhone 4S/5S means there is a critical glitch in the phone’s built-in software. The first thing that is recommended to do in this case is to try to produce forced reboot devices. If this does not help, you will need to restore the device. To do this, it is not at all necessary to resort to the services of a service center. You can restore your iPhone 4S/5S yourself at home. It is important to understand how the operating room recovery procedure differs iOS systems from update. When updating, all data on the phone is saved, but when restoring photos, videos, contacts phone book, installed applications and other information is deleted from the device.

If, nevertheless, the user is set to restore the operating system and is ready to lose all data on the phone, you can begin the procedure itself. To do this you will need the iTunes application.

Everything on Earth is subject to the process of aging, wear and tear. When a cell phone fails, it is always an unpleasant moment for the owner. Because modern addiction people from communications is incredibly large and is determined by many factors Everyday life. There can be incredibly many reasons why the iPhone 4 does not turn on; we will look at the main ones in this article.

What to do if your iPhone won't turn on?

If the phone has not been subject to shock, mechanical stress and did not become a victim of “water procedures”, first of all, make sure active state battery This is quite easy to do. Connect a known-good charger to your phone. If a graphical display of charging progress appears on the screen, the battery is low. If there is no reaction to the connected charger, you will have to remove the back cover in order to get full access to the device's battery. In a situation where the iPhone 4 does not turn on, we can talk about the loss of the starting impulse of the battery. This phenomenon is most often observed in phones that are not used for a long time. As a result, it becomes necessary to force a charge to the battery, bypassing the smartphone devices. the “frog” type will cope with this task perfectly. Opening the back cover and removing the battery is easy. The only complication is that you need to have special screwdrivers for iPhone 4. Since the lower end screws have a star profile, a Phillips screwdriver will be needed to remove the battery cable fastening.

Bringing the battery back to life

After unscrewing the two screws from the bottom end of the case, slide it up and remove the cover of the device.

Then unscrew the two bolts from the short clamp of the battery cable and disconnect it from motherboard. Now install a universal charger on the battery terminals (two outer contacts); 2-3 minutes will be enough to “revive” the battery. Assemble the device and connect the original power supply. If your iPhone 4 still won't turn on, a visit to the service center cannot be avoided. Because subsequent independent repairs at home can be deadly for your mobile device. Don't skimp on qualified assistance. The phone is more expensive when you consider the risk of unconscious iPhone destruction through illiterate actions.

Finally

In some cases, the problem may be explained by the failure of one of the multiple components of the system: processor, power controller, flash memory or any other device chip. Therefore, it is advisable to seek help from professionals, since this type repairs can only be made using special equipment.

The products of the American company Apple have always enjoyed enormous popularity in the world. Every day a large number of people buy new iPhones, iPads and other devices to enjoy the functionality, practicality and beauty of the company’s products. However, the phone may also experience problems, both technical and software. Sometimes the phone cannot be turned on due to a breakdown or any other malfunction.

Let's look together at the reasons why problems occur and how to turn on iPhone 4.

Ways to turn on iPhone 4

iPhone won't turn on by any means

If the iPhone is so damaged that it won’t turn on by any means. in the usual ways, then in this case it must be taken to the service to correct problems in the software or technical sector.

This problem is discussed in more detail in our article.

Mobile phone, this is an integral part of our life, an electronic device that fully satisfies a person in communication. Any object on Earth will necessarily either age or wear out. When a mobile device breaks down, this is not a very pleasant moment for the owner. Modern life has made phones an integral part of life, and human dependence on cellular communications incredibly large, but it is not easy, it is determined by a bunch of factors in everyday life. Even the most advanced and most high-quality equipment in the world - Apple can also break. There may be a lot of reasons why the iPhone 4 does not turn on, the most common

will be discussed in this article.

iPhone won't turn on: reasons

What to do if your iPhone 4s won't turn on?

The main reasons are when the phone has been subjected to shock, mechanical stress, or it simply becomes a victim of water procedures. But if the device has not been subjected to the above factors, then you first need to check the battery, it must be in an active state.

Checking the battery is quite easy. You need to connect a working charger to your iPhone. If an apple appears on the screen and a small battery is visible that is charging, then the problem is with the battery, or it is simply dead. If after connecting to the charger nothing happens, then you will need to remove the back cover. This will provide full access to the device’s battery.

Checking the battery

Sometimes, the iPhone 4 does not turn on due to the loss of the starting impulse by the battery. Most often, this problem happens with phones that have not been used for a long time. To solve this problem, you need to force the battery to charge. You can easily cope with this task using a “frog” charger, it is universal. The cover is very easy to open, as is the removal of the battery itself. Both actions are elementary; no tricks will be used. The only one

The problem is a set of special screwdrivers that are intended exclusively for Apple devices. There are end screws at the bottom and have a star profile, and in order to remove the battery you will need a Phillips screwdriver.

After the 2 screws from the bottom end of the cover have been unscrewed, you need to slide the cover up and remove it. Next, you need to unscrew 2 bolts from the short cable on the battery and disconnect the contacts with the motherboard. Now you can see the terminals on the removed battery; you need to install a universal charger on them. It won’t take much time to revive the battery; 2-3 minutes of charging is enough.

After that, we assemble the device and connect the original charging unit.

For help from specialists

If the iPhone shows no signs of life, and you still don’t know how to turn on the iPhone 4, then you’ll have to go to a service center apple center, or to familiar specialists. Because if you are not well versed in the technology of the device, subsequent repairs by yourself can lead to the death of the phone or serious damage that cannot be fixed.
