Why doesn't the charger charge the iPhone? iPhone won't turn on when charging, what to do - detailed instructions

With the release of iOS 7, all users of the new iPhones that use the proprietary Lightning charging connector experienced certain problems when using non-original chargers and cables. This is due, first of all, to the design of the connector itself, which contains several microcircuits, one of which is responsible for checking the chip located in each Lightning wire for originality.

Cable certification identification is provided by software processes built into iOS. At the same time, it is worth noting that verification mechanisms are regularly updated and it very often happens that iPhone stopped charging after updating the software version. But it also happens that the phone stops accepting charge even when using certified accessories.

What to do if your iPhone stops charging

If there are a few tricks that can fix this:

  • A temporary solution to the situation if the iPhone is not charging with a non-original cable can be to turn off and then turn on the phone with the Lightning cable connected. In this case, there is a chance that the iPhone will start charging.
  • Another option is to do the following: Unplug the power adapter, turn your iPhone into airplane mode, and then reconnect the Lightning cable to the device. If your phone starts charging, you can turn off airplane mode.

If the iPhone still won't charge, there is a possibility of hardware problems.

Let's look at the main options.

Lightning connector is clogged

This is the simplest and most easily solved option. Very often, during operation, dirt and dust particles get into the connector, which over time roll off and disrupt the contact between the connector and the wire. In this case, the iPhone may either stop charging, or the charging process will occur incorrectly - for example, the phone can only charge in a certain position of the wire.

To solve this problem, you need to clean the charger connector, which can be done either independently (but this must be done extremely carefully so as not to damage the contact group of the connector) or at a service center. In a service center, cleaning the Lightning connector is done using compressed air, special reagents and lint, which allows for the highest quality cleaning.

Malfunction of the lower cable / damage to the connector

If the iPhone stops charging, the reason for this may be a malfunction of the lower cable with the charger connector. This occurs due to mechanical damage, oxidation of the cable contacts on the board or connector contacts after moisture, or a microcrack on the cable. In any of these cases, the cable assembly with the charger connector is replaced. In our service center, replacing the lower cable of an iPhone with a charger connector costs from 1,500 rubles (depending on the iPhone model) and is usually completed within an hour from the moment of contact.

Battery fault

Very often, the reason that the iPhone does not charge is a malfunction of the battery, which may lose capacity during operation or begin to polymerize due to exposure to external factors or conditions of use.

The first signs that the battery will soon need to be replaced are a decrease in battery life, the phone turning off with an incorrect charge indication (an iPhone may turn off at 20-30% of the displayed battery charge). In the future, if such problems persist long enough, the battery may stop charging and will need to be replaced.

Charge controller malfunction

The charge controller is a microcircuit on the board that is responsible for the correct operation of the iPhone's power circuits. Most often, incorrect operation of the controller can be caused by the use of low-quality accessories used to charge the device, or a power surge in the network during charging. This problem can occur on any generation of iPhone, but most often problems with the charge controller occur on the iPhone 5 and iPhone 5s.

In such cases, complex board repairs are required at the component level: in most cases, this is solved by replacing the charge controller chip. Please note that such operations can only be performed efficiently if you have specialized equipment, and the technician must have extensive experience in carrying out complex board repairs. Otherwise, there is a possibility of making things even worse - it is not uncommon for people to turn to the specialists of our service center who have already received unqualified service elsewhere.

– the operation is not cheap: Apple gadgets are designed in such a way that the average user simply cannot change the battery with his own hands, so he will have to spend money not only on the battery itself, but also on the work of a specialist. However, there is no need to rush to contact the service center: perhaps it is not a matter of battery wear at all, although the technicians, of course, will not report this and will definitely “attribute” the most “expensive” problem.

Common reasons why an iPhone refuses to charge are:

Lightning (30 Pin) clogged. People who like to carry their smartphones to the beaches most often encounter this problem - the charging connector gets clogged with sand and the plug cannot fit into the hole as it should. Not only sand can damage the connector - dust, lint, and pieces of fabric accumulate in trouser pockets. Solving the problem of a clogged charging connector is simple: you need to clean the hole with a toothpick.

The main thing: do not use sharp metal objects, such as a needle, for cleaning - this can damage the contacts.

There is a problem with the USB port or outlet. Apple recommends recharging gadgets from electrical outlets, and not from USB ports - the ports have a completely different purpose, namely information exchange. However, if you don’t have enough sockets in your room and you have to periodically recharge your gadget from your computer, you’ve probably noticed that some of the PC ports simply don’t charge your iPhone. The problem is the current strength: The USB port has an output of only 0.5A, while charging an iPhone is 1A. Therefore, the gadget always takes longer to “refuel” from the port. If your smartphone refuses to charge, try changing the USB port (there are usually 3-4 on PCs and laptops) or socket.

Cable fault. The cable included with the iPhone is quite fragile - if you constantly bend it, the outer braid will break very quickly. It’s easy to unintentionally damage “exposed” conductors. If it breaks, buy a new one CERTIFIED cable. Please note that if you buy a Chinese accessory of dubious quality for 150-200 rubles, you risk throwing money away - Apple developers have taught Lightning to “recognize” certified cables, so fans of counterfeits can easily see the following message on their iPhone 5:

Users of iPhone 4 modification with a 30 Pin connector will not encounter this message.

Component failure. With such a problem, there is a direct route to the SC. One of three malfunctions is possible: connector module failure(removal price – 500-800 rubles), power controller failure(1400 rubles), battery failure due to wear and tear(the most “expensive” malfunction - you need to stock up 2500-3000 rubles). Approximate prices are given: of course, the cost of work and components will vary depending on the region of the Russian Federation. Advice: Make sure the quality of the work done is still in the service center - recharge your smartphone by at least 2%.

What to do if your iPhone stops charging: step-by-step plan

If the gadget is not “powered” by the original charger, proceed as follows:

Step 1. Reboot your smartphone. This solution is so banal that users, paradoxically, often neglect it. A simple reboot can solve a lot of problems with the gadget.

Step 2. Check the cord, charger, USB port, outlet. Checking, for example, the unit is quite simple: disconnect the cable from it and try to “power” the gadget from USB. If there is a result, the problem is probably in the block, because the cable is working.

Step 3. Clean the charging connector. How and with what to do this has already been discussed earlier.

Step 4. Use Recovery Mode– enter iPhone into recovery mode. Mode Recovery Mode Its effectiveness is similar to a simple reboot, however, it copes better with technical problems (including being able to help with charging problems).

note: After a disaster recovery, the iPhone settings are reset to factory settings, so take care of the safety of important data in advance.

The gadget is put into mode Recovery Mode like this: the user first turns off the iPhone, then presses the " Home” and finally connects the smartphone to the PC with a cable. The following picture on the screen indicates that you are in recovery mode:

Exit from Recovery Mode can be done by long pressing on " Power».

Step 5. Take the gadget to the service center if none of the above measures helped. The iPhone needs high-quality diagnostics and “surgical intervention.” Despite the high cost, waiting to replace the battery or charging connector will not take more than half an hour of your time.

Conclusion

No matter how reliable and durable the manufacturer presents its product, the user needs to be prepared that one day he will still have to contact the service center. In the case of Apple equipment, malfunctions of the charging connector and battery are among the most common. To avoid costly repairs and not become a victim of an unscrupulous (or unqualified) technician, it is recommended to take advantage of the extended warranty offer from the manufacturer AppleCare. With such a guarantee, you will have peace of mind for your smartphone for 2-3 years.

One of the most common problems that iPhone owners encounter is charging problems. If the iPhone does not charge at all or the process is too slow, the reason may be either problems with the software or a malfunction of the phone or charger.

Some defects can be removed yourself; to fix others, it is better to contact a service center or workshop where specialists with a sufficient level of experience work and have the necessary spare parts for different generations of iPhone and equipment.

Most often, problems with charging the device are caused by the following phenomena:


Replacing the socket

If the Lightning port where you plug in the charging cable is faulty due to debris getting inside, you need to carefully clean it.

A thin and long object made of plastic or wood is suitable for this; Never use metal devices such as paper clips, as they can damage the contacts with static electricity.

After mechanical cleaning, you need to blow out the connector and check whether the cord can be detected. Often, after the procedure is completed, the iPhone charges normally.

If cleaning the socket does not help, the reason may be its mechanical damage: the case near the port will heat up, and when connected, the LED indicating the charging process may blink and turn off.

In case of burnout or mechanical damage to the contacts, the help of a technician is usually required, since the problem becomes the failure of the lower loop. This part cannot be repaired and must be replaced with a new one.

When making repairs, it is important that only the original is used for replacement, since cheaper Chinese analogues are rarely of decent quality, and when installing them, the repair will have to be done again after 2-3 months of operation.

Battery Replacement

All iPhone models have a lithium-ion battery, the service life of which varies from 6-8 months to a year depending on operating conditions. After 400-800 full charge cycles, it drains much faster and takes longer to charge. In addition, battery damage can be caused by the following factors:

  • Mechanical phenomena (fall, directed impact).
  • Using low-quality adapters instead of the original charger.
  • Liquid ingress, oxidation of battery contacts.
  • Short circuit.

In any of these cases, it is better to replace the element: a new battery will hold a charge better and eliminate the hassle of long-term connection to an outlet. A replacement is most often ordered from a service center, since the iPhone’s design is monolithic, and you cannot simply remove the battery, as on most smartphones. To replace it, use a set in the form of a Phillips screwdriver and a special Pentalobe and a plastic spatula. Basic actions:

  • The screws at the bottom of the device are unscrewed with a Pentalobe screwdriver.
  • Using a spatula, the screen of the gadget is raised.
  • The battery cable is held on by three screws; you need to unscrew them and disconnect the cable.
  • The battery is removed and replaced with a new part, assembly is carried out in the reverse order.

Software glitch

Often the cause of problems with charging a device is a failure in iOS: this may be a freeze of the operating system itself, which causes a delay in the response of the controller responsible for supplying current to the battery. To resolve the problem, you must perform the following steps:

  • Press the Lock and Home buttons at the same time, hold them in this state for 15-25 seconds, without releasing: a white background with the Apple logo will appear on the display, then it will cease to be visible, and the keys can be released.
  • Turn on your smartphone and connect the charging cable.

This procedure is known as a “hard reboot” and helps if the cause is an OS failure. As a rule, after this the power problem disappears.

Problematic firmware

Some users are faced with the fact that after they decided to change the firmware or install an update, the iPhone stopped “seeing” the cord. The problem may be that the update process fails, an application that is not certified is installed, or a virus is launched. You can solve the problem in the following ways:

  • Roll back to the previous firmware version. This option is suitable for users who save a backup copy before updating: this will allow you to return the previous settings using iTunes. To do this, you need to go into the program and click on the restore button.
  • Restore original settings. The method is used in other cases, however, this deletes all multimedia files and settings, so before using it you need to take care of resetting the data to the computer.

If after these steps there is still no reaction, most likely the reason is mechanical damage to the elements of the device.

Water ingress

If moisture gets inside the iPhone, it not only leads to damage to the processor chips, but also to power problems. As a rule, in this case, the smartphone screen turns white or has stripes, the apple-shaped indicator blinks and turns off, and the iPhone cannot be charged.

The situation is complicated by the fact that it is difficult to disassemble the equipment yourself, and water can damage the most important contacts, and a short circuit will disable it completely. In some cases, if little water gets inside, only a few parts have to be replaced, including the battery itself; in others, important processor components burn out.

If water gets in, you should take the device to a service center as soon as possible, after wiping the outside of the case and screen to remove moisture.

It is not recommended to try to turn on the iPhone after “drowning”: this will increase the risk of a short circuit and significantly complicate repairs. In no case should you use “folk” methods such as soaking the device in rice, which will absorb water: the main damage is caused by microcrystals of salt dissolved in the liquid, which, after drying, remain on the surface and can penetrate deeper.

During the service, the smartphone is disassembled, each part is dried using special equipment, treated with cleaning compounds, after which the repairman inspects the elements. If there is damage, the failed parts are replaced.

Conclusion

iPhone power failures can be associated with various phenomena, which the service uses diagnostics to determine. If you don't know what to do if your iPhone won't charge, don't try to use DIY methods, disassemble the device yourself, or change parts. Without the necessary knowledge and experience, you can damage the equipment more, which will affect the complexity and cost of repairs. In case of serious problems such as a broken port or freezing, it is better to contact the service immediately.

Despite the fact that gadgets branded iPhone 5/5s are considered one of the most modern in the electronic world, they are still susceptible to breakdowns and various types of defects. They can be both external and internal, depending on the operation of the device or its initial problems. That is why, to the question why the iPhone does not charge, you can find more than one or even two answers. What to do if a similar situation overtakes an active gadget user, we’ll talk further.

Hardware glitch

There are several reasons for the iPhone 5/5s charging process to fail, but as statistics show, perhaps the main one is a malfunction in the gadget’s software or, more simply put, in the firmware. Any smartphone under this brand, like any other, contains inside an electronic board on which various microcircuits, controllers, etc. are located. One of these components, namely the U2 IC microchip, is responsible for the logical chain of the on-board battery charging process.

The main cause of circuit failures is, oddly enough, the use of counterfeit chargers. The manufacturer categorically prohibits doing this, but, as they say, you can’t order your heart. The fact is that when the power supply is connected, its electronic unit and the microchip on the iPhone board exchange checksum signals to prevent excess charging currents.

If you ignore this point at your own peril and risk, the controller may be damaged, and this will cause a break in the power supply or, more precisely, in the control of this process.

As a result, the battery cannot normally or even refuses to accumulate energy for the simple reason that it does not understand how this should happen (from the point of view of the logic of the microcircuit).

Problems with the power supply

The next reason that disrupts the charge accumulation process of the iPhone 5/5s battery is the breakdown of the power supply itself or, as it is called, the Lightning cable. The original component, despite its manufacturer status, turns out to be fragile and subject to rapid wear. If this happens, then the owner of this gadget essentially has only one option - replacing the defective unit. And this is where the mentality and the desire to save on things that are strictly prohibited come into play.

It's no secret that original memory devices not only from Apple, but also from other flagships on the market are by no means cheap. At the same time, Chinese analogues, which can be easily purchased on any international shopping site, for example, AliExpress, are several times cheaper. If you do this and then connect it to the iPhone 5, then at best (and this is not a joke) the charging process will not start at all. In the previous case, it was already mentioned that when a charger is connected to an Apple smartphone, data is exchanged at the microchip level - a kind of proprietary Lightning cable authentication mechanism. If the checksums do not match, a service message may appear on the screen: “ This cable or accessory is not certified and therefore is not reliable to operate with thisiPhonenot guaranteed».

When the check for some reason was successfully passed or bypassed, and the gadget began to charge, it’s too early to rejoice. More precisely, a surge of joy can certainly overwhelm the owner, but for the reason described in the previous case, it may not last long, but the frustration of having to replace a board or microchip is much more impressive.

Battery damage

iPhone 5/5s belongs to the category of gadgets that are equipped with high-quality and durable batteries. But nothing lasts forever in this world, and any battery has a finite service life associated with the number of charging cycles.

If the device is used quite actively, then most likely the on-board battery will have to be replaced within two to three years.

The main snag in this case is the “monolithic body of the smartphone”, which does not have the back cover usual for most other mobile devices for quick access to the battery compartment and SIM cards. It is extremely problematic to disassemble it yourself without damaging the sensitive elements of the board, microcircuits and housing. Doing this at home without the appropriate knowledge and tools is not recommended. Therefore, in this case, the owner should contact a certified service center.

Problems with the power connector

No less common are cases where the root of the problem is the Lightning connector of the iPhone 5/5s. Problems in this part can arise for at least three reasons:

Reason independent

Charging the iPhone 5/5s involves connecting the electrical circuit of the gadget (via a connector) and a power source (household power supply, a third-party gadget, such as a laptop or PC), through an adapter with a USB port or directly through the port itself. If all of the above possible reasons for the battery charging process failure are rejected, then you need to look for the problem not in the device itself, but in the power source. In other words, you need to diagnose the USB port.

Possible roots of the problem are that the iPhone's charging circuit and the power supply with a standard USB port may have different characteristics. In the first case, it is 5V/1A, and in the second - 5V/0.5A. Failure to match operating modes can also cause the iPhone to not charge.

Don’t rush to get too upset, this problem is solved in 95% of cases, I have encountered it myself. In this article I will tell you what actions can and should be taken to understand the cause of this malfunction and how to deal with it. There can actually be many reasons why the iPhone 5s does not charge, because it is a complex device. Let's see what options we have:

  • Software failure;
  • Malfunction of the cable or charger (plug, or charger - charger);
  • The charging connector is broken;
  • iPhone motherboard is faulty.

We will start with harmless problems that can be easily solved at home without a visit to a service center.

iPhone 5s does not charge well due to a firmware glitch.

In fact, this happens very rarely, but what the hell, as they say. Try rebooting your phone. To restart your iPhone 5s, you need to hold down the Power button and the Home button until the phone turns off and the boot apple appears. This may take up to 25 seconds. If it helps, great! And if charging still does not proceed, move on to the next point.

iPhone 5s won't charge or won't turn on due to cable or charger.

iPhone 5s may not charge due to a faulty cable or charger. I think this doesn’t surprise you :) Therefore, if rebooting doesn’t help, then try some magic with the cable or charger.

First, make sure the outlet is working properly. If you are using an extension cord or pilot, check that the power button is in the “ON” position. Sometimes the iPhone does not charge from the charger for this very reason.
When Apple switched to new Lightning cables, the whole world was indignant, but accepted the new connector. However, not everyone knows that this cable has literally become smart! It has a built-in chip that is responsible for recognizing the originality of the cable when connected to the phone. Cheap cables use non-original chips, which can cause errors when recognizing the cable and, if they fail, they can, at best, stop charging the phone, and at worst, damage the power controller of the iPhone 5s.

Therefore, if the iPhone does not charge from the cable, try using another one; perhaps the phone simply does not see the charging. A faulty Lightning usually displays a message something like this: “this accessory or cable is not certified”. The charger plug itself is not as smart as the cable, but it can also fail.

It’s also worth knowing that the iPhone 5s may not charge from a computer either. This is due to the fact that for correct charging the current must be 1 Ampere, but not all computers can output that much to the USB port; most often it will be 0.5. For the same reason, if you charge your iPhone using a cheap Chinese plug that gives out 0.5 Amperes, then most likely the iPhone 5s will not charge, and sometimes even slowly discharge.
It is better to use original accessories, it is not cheap, but it is safe.

iPhone 5s charging connector.

Quite often the charging connector fails. It accounts for about 70% of calls to the service. A typical symptom of a faulty connector is that the power connection indication constantly “jumps”, that is, the cable seems to be connected and immediately disconnected, or the charge only occurs in a certain position of the plug.

The cause of iPhone 5s connector failure is usually either moisture or broken connector contacts. In the first case iPhone won't charge due to the fact that the contacts are oxidized, and in the second due to a sunken or broken contact. The replacement procedure is standard; the connector is replaced as an assembly with the lower cable. It also contains a microphone, speaker contacts, an audio jack and a GSM antenna; this part is not dismountable. iPhone repair takes about 20 minutes including testing.

iPhone 5s stopped charging due to battery.

This also happens often. In this case, the standard symptom is the lightning indicator next to the battery, but the battery is not charging. Another sign of a faulty battery is the eternal boot apple. The apple lights up on the phone, stays on for a while and goes out, then after a couple of seconds it lights up again. A common cause of malfunction is simple - battery wear. In this case, there is no need to worry; everyone faces this sooner or later.

If the iPhone 5s does not charge after replacing the battery, then try to claim warranty; most likely the battery is defective. You can find out more about this problem in the article replacing the battery. By the way, when I said that I also encountered a charging problem, in my case it was the battery that was to blame. Which is generally not surprising, he lived for almost 3 years.

iPhone 5s discharges and charges quickly or slowly, and gets very hot.

Now we come to the most serious possible problem - a faulty motherboard. Due to falls or the use of a non-original cable or charging, the charging controller (U2 Tristar) or the main power controller may fail. The symptoms are as follows:

  • iPhone 5s is completely discharged and will not charge;
  • In standby mode, the phone discharges quickly;
  • iPhone 5s only charges when turned off;
  • iPhone charges very slowly;
  • The phone gets very hot when charging.

Despite the fact that this breakdown is quite serious, we can fix it without any problems. Repairs can take from several hours to several days, depending on the complexity of the situation. You can read more about such repairs in the article Replacing the iPhone 5s power controller.

Summary.

So we hope we figured out why the iPhone won’t charge and what to do in this case. If this article helped you, I’m glad, my task is completed. If you have any questions or require repairs, call, write or come, we will definitely help you!
