Iphone 4 is not charging. Checking the charger

Youtube

Anyone can have charging problems. Apple models for several reasons at once. This complex device is a high-power microcomputer and therefore requires very careful handling. Therefore, if it is necessary to repair such equipment, you must contact professionals, such as, for example, specialists from the AppsGRADE center http://www.appsgrade.ru.

Disturbances during the charging process are often the result of damage to the wire, falling into water, a strong impact, and other reasons.

Why iPhone won't charge: main reasons

The method of repair and its cost will depend on the cause of the malfunction. Let's look at the most common cases, starting with the simplest:

An elementary reason that many for some reason do not pay attention to is defective Charger. It may also be damaged by impact or damage to the wire. If your iPhone stops charging from a wall outlet, you should check it with a different charger. If there are no problems, then you should just buy a new charger. This is much cheaper than a full iPhone repair.
If the iPhone does not charge when the adapter is working, it is quite possible that the problem lies in the connector of the phone itself. It may become clogged due to lint if the phone is carried without a case. Also, the connector oxidizes when water gets on it, so you should not use the phone during rain. Service center technicians even encounter situations where a person speaks on the phone while standing in the shower, and then complains about malfunctions. If the connector needs cleaning, it should only be carried out by a specialist, as this is a complex and very delicate job.
If the connector is damaged after being hit or dropped, it must be replaced. This is one of the common solutions to the problem and a quick answer to the question of why the iPhone won’t charge. The new connector can work for many years if the phone is handled correctly. It is no secret that the iPhone does not charge in most cases precisely because of incorrect operation. It should be noted that you should not give the gadget to small children, as in this case it may very soon fall to the floor. Young researchers around the world love to experiment, which can cause serious damage to the apparatus.
Many people are interested in why the iPhone does not charge from the computer or does it very slowly? The fact is that a standard USB connection is not designed to charge such a complex device. Since a laptop usually runs several applications at once, the phone spends its charge faster than it gains it. By the way, have you ever wondered why the iPhone charges quickly in airplane mode? The answer is simple: in this mode, everything is turned off additional functions, so charging really speeds up.
If the iPhone is discharged and does not charge, then the problem may be related to the controller chip. It may suffer, for example, due to charging a gadget in a car that was not carried out according to the rules. In this case, the technician begins work with diagnostics, which will identify the cause of the violations. Replacing a microcircuit is done quite quickly, especially if you are not turning to amateur beginners, but to real professionals. To find out why the iPhone 5 is not charging, the technician will conduct full diagnostics, since a fall or other damage could cause damage to internal parts.
One of the biggest reasons why an iPhone won't charge is a faulty battery. It doesn't happen that often, because Apple uses only the most reliable components, but sometimes the battery needs to be replaced. One of the signals that the battery is malfunctioning is that the gadget does not fully replenish its energy reserves, and begins to discharge within an hour. Replacing the battery will result in iPhone charges quickly, and the battery holds a charge well even with several applications running.
Incorrect use, incomplete charging or storing the phone in a discharged state will shorten the battery life, after which the battery will have to be replaced soon. By the way, you know how much time can work Apple battery? According to the documents, when correct use it can easily withstand up to 400 discharge and charge cycles, while the connection time to the adapter should not exceed four hours.

But the chance that the battery will fail is empty space one in a million.

A little food for thought - when you plug your iPhone or iPad into a power source, you don't plug the outlet directly into the battery. Think about it—you're plugging a cable into a port on the bottom of your iPhone, and that port isn't directly connected to the battery. After iPhone connections to the power source, it is the software that decides whether to start charging.

Replacing the battery in order to get rid of charging problems will most likely have no effect! If the hardware is causing the problem, the problem is most likely with the charging port on the smartphone, and not with the battery!

Why won't my iPhone charge via a USB cable from my computer?

Check your USB cable for damage. Carefully inspect the USB you are using for charging on both sides. If you see visible signs of damage, then it may be time to change it.

How can you find out if the USB cable is the reason: “Why doesn’t the iPhone charge and doesn’t see charging?”

If you don't see any visible damage (pardon the tautology) on the outside of the cable, try plugging your iPhone into a USB port on your computer instead of using a wall outlet. If you used USB port computer, try using a power outlet. If the phone only charges in one of the cases, the problem is not with the cable.

The best way to determine if your cable is damaged is to use a friend's cable. If your phone suddenly came back to life, you have identified the reason - the USB cable is damaged.

Don't forget about your iPhone's warranty!

If the iPhone is still under warranty, the USB cable (and the rest of the items that came standard with the iPhone) are also covered! Apple will replace the cable free of charge if it has not yet been destroyed.

You can make your return online at or call your local Apple Store to contact tech. support. If you decide to visit the Apple Store in person, it would be wise to give advance notice so you don't have to wait in a long line.

Problem with cables not made by Apple

One of the most common causes of iPhone charging problems comes from low-quality USB cables purchased from Aliexpress, local stores, etc. Yes, cables from Apple expensive, but their quality justifies the cost.

Try using a different charger if your iPhone stops charging

There are many ways to charge your iPhone: from a wall outlet, car, computer, laptop, and many other power sources.

Remember, it's the software that says "Yes" or "No" when you charge your iPhone. If the software detects power fluctuations, it will automatically stop charging as a protective measure.

How can you determine if the cause of battery charging problems is a faulty charger?

Same as with the USB cable, The best way– use another charger (ask your friend or relatives). It is advisable to try more than 2 other people's charges, as some can be very picky.

If your iPhone won't charge from a wall outlet, try using the USB port on your PC. If your iPhone charges on one adapter but not on another, the problem lies with the adapter.

Note: If you charge your phone via Apple keyboard, or via USB hub, try connecting your iPhone directly to the USB port, as this may be the problem.

Use a brush to clean the port of debris when the iPhone does not see the charger

Use a flashlight to carefully examine the charger port on the bottom of the iPhone. If you see a lot of dirt, perhaps this is the reason why the iPhone does not see charging and does not charge. The port has several small inputs (9 on the USB cable) and if at least one of them does not work, you will not be able to charge your smartphone.

If you find dirt, dust or other debris in your smartphone's port, use a brush to clean it: Take a toothbrush and gently brush the cable input of your iPhone.

The charging port may have been damaged by liquid.

One of the most common reasons Charging problems are due to liquid damage. In this case, even if you clean all the dirt, the problem will not be solved as your phone has already been damaged.

When accessing the network in service center(Apple Store) with a request to repair the charging port, which was filled with liquid, the only option that can be offered is to replace the entire iPhone. If you don't have AppleCare+, this can be very expensive. However, it is impossible to save photos, videos, or other personal information, hosted on an iPhone.

Put your phone into DFU mode and perform a recovery

Even if your iPhone doesn't show that it's charging, DFU mode may still work! DFU recovery This is a special type of recovery, with it you reset your phone to factory settings, but your data will be lost. This will help solve software problems if they were the cause of battery problems.

Some of iPhone users may encounter a situation where, when connecting a charger, their smartphone simply does not charge, and the culprits of this dysfunction may be due to reasons at both hardware and software levels. In this material, I will tell you what to do if the iPhone does not charge, but shows that it is charging, I will describe the causes of this problem and the specific methods of solving it.

The reasons that the iPhone is not charging, but shows that it is charging are as follows:

Damage (breakage) of the cable. If your cable is damaged (physical wear, animals, children, etc.), then you will not be able to charge your iPhone, and in some cases, although you will see signs of charging, de facto it will not occur;
Damage to the charging port (Lightning). Usually caused by physical wear and tear, as well as strong (sudden) user movements when connecting and disconnecting the cable;
The port is clogged with dirt. During long-term use of the phone, its exposure to various fleecy (dirty) surfaces, the socket may become clogged with small pieces of wool, dirt, dust, etc., which leads to insufficient contact of the cable plug with the port;

Charger problem. For some reason, your device (physical wear or incomplete compliance with the declared characteristics) does not provide the stated charging parameters (usually 5V and 1A), and this leads to various problems with smartphone charging. This is especially true for devices from little-known manufacturers (the so-called “noname”);
Battery problem (usually wear and tear). Over time, the battery wears out its life and requires replacement. If you have been using your iPhone for a long time, or purchased it secondhand, then it is likely that the battery of your device has exhausted its resource;

Physical damage to the phone board. If your phone has received any physical damage, fell or experienced any other mechanical influences, then it is quite possible that they had a negative impact on its functionality, including the ability to charge it;
Problems with the controller responsible for charging the phone.

iPhone won't charge - software reasons

Among the reasons why you cannot charge an iPhone, there are also software reasons, and some experts call them prevailing. Basic software reason is a malfunction of the software (at the smartphone firmware level), which for some reason does not give a command to the phone controller to charge, so charging simply does not occur.

Also, the reason why the iPhone refuses to charge is that the user uses incorrect (custom) firmware in his device (similar firmware is available for versions iPhone first generation, iPhone 3G and 3GS, iPhone 4, iPhone 4Rev A).

How to fix iPhone charging problem

Check the charging controller (or lower cable) at a service center. If your iPhone does not charge, quickly loses charge, or gets very hot, then this may be an indication that the controller is at fault. If the controller is faulty, repair (replace) it;
Replace the battery. If you have been using your phone for a long time, the battery may have exhausted its life. Replace it.
Contact your nearest service center; the board of your smartphone may be seriously damaged due to some accidental physical impact.

Video illustration of the error correction

Above, I listed the reasons why the iPhone does not charge but shows that it is charging, and also listed what to do in this situation. A good option is full reboot (hard reset) devices, as well as cleaning the smartphone port from dirt accumulated there. If you have tried all the options and nothing helps, then contact your nearest service center - perhaps the problem of poor charging is in the device board itself, and your device requires a thorough repair.

In contact with

Some equipment owners famous brand Apple is faced with the fact that the iPhone does not see charging or charges every other time. This product is quite reliable, but there are cases when various reasons it fails. It is worth knowing that if the gadget has stopped charging, various factors may contribute to this. In this article, we will analyze the possible causes of the gadget malfunction and ways to solve the problem.

Why does the gadget stop taking charge?

The reason why your iPhone won't charge may lie in the phone itself or in its charger. To find out, connect the gadget to a similar, working charger. If after connecting the charger it does not work, this means that the problem is still in the phone. The iPhone connector can become damaged as a result of:

mechanical impact (cable rupture or damage, shock, device falling)
contact with liquid
dust, lint, or debris getting into the charging connector

Software glitches may also be among the reasons why the iPhone stopped charging. As a result of failures, errors occur and the phone controller does not receive commands to charge.

The port may fail due to careless handling, sudden movements when connecting and disconnecting the charging cord to the network. As a result of a fall or impact, the following may become unusable:

power controller
cable connecting the connector to the board
charging connector

It will not be possible to perform a high-quality replacement of the cable and microcircuit on your own.

If water gets inside the device, it can lead to corrosion of internal parts, including the charging port. There is a chance to avoid damage if immediately after contact with the liquid you turn off your iPhone and do not use it for several days.

If the phone is often placed on dusty surfaces or in clothing pockets, then lint, dust, debris and other small particles get into the charging connector. This results in insufficient contact between the port and the cable, resulting in the iPhone not becoming infected.

The reason why your iPhone won't charge could be a faulty battery. Since the battery is designed to last a certain number of charge cycles, it may have reached the end of its life and it's time to buy a new battery.

In addition, the use of uncertified chargers may damage the chip that controls the battery charge, the sleep button and USB functions. In rare cases, using an inappropriate cable may cause your gadget to catch fire. Cheap chargers do not stabilize the voltage in the network, which prematurely damages the battery.

Symptoms of faults

There are several clear signs that indicate a faulty iPhone charging circuit. These include the following:

the phone is connected to the network, but the charge indicator is not lit (flashing) or shows incorrect data
The device turns off before the battery is fully charged
The device stopped seeing charging
iPhone only works when plugged in
Battery indicator blinks constantly
iPhone charges if you move the cord in the connector

You should immediately pay attention to these signs, as they indicate that your iPhone's charging has stopped working. It should be repaired immediately.

What to do if the device cannot be charged?

To repair Apple equipment, in particular the iPhone, you need special knowledge and experience. But before turning to specialists, try to perform a few basic steps yourself. They can be useful when the iPhone does not see charging.

First of all, check iPhone port for the presence of dirt, debris, and foreign objects. Unnoticeable lint and dust in the connector can cause the device not to charge at all or to receive a charge only once. To eliminate this problem, take an ordinary toothpick and carefully clean the connector through which the iPhone is charged.

If your iPhone doesn't charge after updating or suddenly stops charging, try uninstalling or disabling the latest installed software, then restart your iPhone.

If your iPhone's charging doesn't work well or the gadget stops working altogether, reboot it. For this:

Press the Home and Power buttons simultaneously
hold both buttons for 15 seconds
wait until the gadget turns off and on

After restarting, the network connection sound should appear. If your iPhone has stopped charging and you can’t get it to work this way, you need to try other methods.

If, after some time after connecting the phone to the network, the charger stops charging, move the cord in the gadget connector. If the phone starts charging, then the connector needs to be replaced. It is better to contact specialists with this problem.

It is not uncommon for an iPhone charger (cable) to become unusable. To check this, try charging it new gadget Apple company. If charging does not occur, the cable is damaged internally or externally. In this case, it is advisable to replace it with a new, high-quality one.

It may take up to 12 hours to charge the battery with a non-original charger, and it may seem that charging has stopped working. Therefore, it is better to use the original device.

With breakdowns mobile technology Almost every user has encountered this problem. It’s good when faults are detected immediately - there is a chance to return the equipment under warranty. But most breakdowns are discovered later. One of the most common problems is related to the charge battery. Owners of Apple devices are wondering why the iPhone is not charging, although just recently everything was fine?

Checking the charger

If your iPhone 4S (or any other iPhone) is not charging, you should immediately check that the charger is working properly. To do this, you need to find another iPhone and connect the problematic charger to it. Successful start battery charging indicates that everything is in order with the charger. This means that the problem is with the smartphone itself - it needs to be taken to a service center, where it will be examined by repair specialists.

Don't have another charger? Then you can connect the current charger to another iPhone and check its serviceability. If another smartphone is charging, then the problem is with your smartphone - it is quite possible that it needs repair.

But what to do if your iPhone won't charge? Then we take our wallet and go to the nearest mobile phone store or company Apple store to buy a new charger. An equally correct solution would be to check the integrity of the charger cable– it is quite possible that this is where the problem lies (buying a new cable will cost less than buying a new charger). You can get the cable for testing from your friends or acquaintances.

You can also use a computer with iTunes to check the integrity of the cable - if the cable is intact, iTunes will detect the connected device.

When buying a charger, give preference to original accessories - thanks to this you will get rid of problems with charging the battery. In addition, the service life of original accessories is disproportionately longer.

Checking the battery

We already know what to do if the iPhone 5s does not charge (as well as any other iPhone) - you need to check the charger and do not forget to check the cable. What should you do if your iPhone is not charging, but shows that it is charging? Possible reasons malfunction occurs:

The battery life is exhausted;
The charger is broken;
The charge control circuit has failed.

If the iPhone shows charging, but does not charge, then the problem may be due to the exhaustion of the battery life. The charging diagram shows that the charge is in progress, but the battery cannot replenish the supply of electricity. What to do? Try turning off your smartphone and charging it overnight - there is a chance that the battery will slightly restore its properties. If there is no improvement, contact a service center to replace the battery.

As we remember, on the original iPhone smartphones are used non-removable batteries– their replacement is carried out at service centers.

iPhone 6s won't charge even though the charging indicator indicates otherwise? Try using a known-good charger - it is quite possible that your charger is faulty and cannot provide normal charging current. If another charger does not help, you should contact the service center.

Other repair methods

Has your iPhone stopped charging even though everything was fine just yesterday? In some cases, the problem is solved by resetting the smartphone to factory settings.- the whole point is some kind of malfunction in the on-board software. If this approach doesn't help and your iPhone still won't charge (or pretends not to charge), try restoring via DFU mode– sometimes it helps.

If there are no changes, contact your nearest service center - the fault lies in system board your iPhone.
