iPhone 4 won't accept charge. The battery is faulty

– 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, whereas iPhone charging– 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. Cable from iPhone kit quite fragile - if you constantly bend it, the outer braid will break very soon. It’s easy to unintentionally damage “bare” 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 fakes 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 original charger, proceed like this:

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 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. iPhone needs 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 case of Apple technology 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.

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 the serviceability charger. 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 original smartphones iPhones use non-removable batteries - they are replaced 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.– it’s all about some kind of glitch 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.

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:

1. An elementary reason that many people for some reason do not pay attention to is a 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.

To always stay connected, do not forget to charge your smartphone in a timely manner. Unfortunately, sometimes mobile device does not react in any way when connected to a power source. If your iPhone is not charging, then the problem can most often be solved simple actions. We also figured out why sometimes the iPhone does not charge from Power Bank.

1. Plug the cable into the gadget.
2. Insert the second end of the cable into:
   • USB socket adapter.
   • Into the USB port of the computer.
   • Certified Accessory: Externally powered docking station or hub.

After this, you should see a large image of the battery on the screen (in lock mode) or a lightning bolt in the status bar.

If your smartphone does not respond to charging - there is no lightning icon - or shows charging, but is not charging, first check the most simple reasons problems:

1. If the phone is completely discharged and turns off, and then does not turn on or charge, leave it on charge for 10 minutes. If there is a severe loss of charge, the screen may remain black for the first time, without indicating the process.
2. Inspect and feel the cable for kinks, breaks and bent contacts. Use only certified wires. If you suspect cable damage, try connecting iPhone 4 with another one.
3. Inspect the port on your smartphone, especially if you carry an iPhone 7 or 6s with a Lightning connector without a closed case in your pocket. Dust is easily forgotten in the port, short contact pad Lightning cable no longer fits tightly, and therefore the iPhone 6, 6S, 4 or other model does not charge. The solution to the problem is simple - take a clean toothpick and carefully remove the dust and lint. Additionally, blow the port with air and connect it to a power source.
4. If iPhone 5, 6s or another model does not charge from a computer via USB, switch the wire to a different connector. Some USB ports may simply not work due to their breakdown or incorrect connection, so the PC does not see the attached gadget and does not respond to it.

If after all the checks the iPhone 5, 5S still does not charge, we look further for reasons.

"The accessory is not certified"

In the fight against counterfeits, Apple engineers have taught their products to recognize the authenticity of cables. To do this, the plug is equipped with a special chip that tells the phone which wire it is going to be plugged into the socket. If the iPhone stops charging completely and displays a message about connecting an uncertified accessory, change the cable to an original one.

If such a message appears when using the “native” wire, check its integrity, clean the iPhone port and reboot the device.

Software problems

Another common reason why it won’t charge is failures software. If errors occur in the operation of iOS, a command is not sent to the controller and charging does not occur. The problem is resolved by forcing a reboot:

• On iPhone 7 and higher: hold down the power and volume down keys for 10-15 seconds until the Apple logo appears on the display.
• On iPhone 6s, 5 s and younger: hold down the power and “Home” keys.

And it will turn on, after which it will begin to respond to charging.

When to go to service...

Some problems cannot be resolved on your own. If the power controller breaks down due to impact or water, or the battery life has expired, you will have to contact service. Signs of internal damage - the phone does not charge and does not turn on, quickly loses charge, gets very hot, or the iPhone shows that it is charging, but the charge does not increase.

If you've been using your iPhone for more than a year, its battery will start to drain faster and faster. Over time, the intervals between recharges can be significantly reduced - replacing the battery will solve the problem. Please note that on a smartphone non-removable battery, so trust her to change service center. You can remove the battery yourself only if you can properly disassemble and reassemble the gadget.

Charging from Power Bank

There may be several reasons why an iPhone does not charge from a Power Bank. First, check that the cable is working properly and connect another device to charge. If everything is fine with the wire, and the Power Bank does not charge the iPhone 5s, 6 or another, investigate:

• Output current: iPhone requires 1 A.
• Use original wires Apple, and not complete ones from Power Bank - too thin a section reduces the voltage and current.
• Capacity ratio external battery and phone: for successful fully charged The gadget's battery capacity should be 2 times less. IN regular iPhones 1700-1900 mAh batteries are installed, in Plus line– 2800-3000 mAh. For Chinese Power banks, the actual power may not correspond to the declared one.

If all the parameters are in order, but when connected, the Apple gadget does not charge, although the charge of other devices on this Power bank increases regularly, the device is not compatible with your smartphone.

If the charging process is progressing, but extremely slowly:

• Unload applications from your smartphone memory - double-click on “Home” and swipe up unnecessary programs. Skype, instant messengers, games, browser with open tabs– all of them constantly waste the device’s energy. To speed things up, you can turn off your phone altogether.
• Calibrate the batteries of the Power bank and smartphone - you need to completely discharge them 2-3 times before turning off the device, after turning them on, leave them to charge to 100%. This will help adjust the power controller and avoid accelerated discharge or sudden shutdown.

Conclusion

We figured out what to do if your iPhone won’t charge from a charger or Power bank. Most causes can be eliminated by the simplest actions - cleaning the port, changing the cable, rebooting the phone. If the phone dies and refuses to turn on after all the manipulations, take it to the service center, where specialists can see and fix the problem.
