Why does my iPhone not charge when turned on?

Do THIS if your iPhone won’t charge

Many users buy Apple products for their high quality and reliability. But all hardware is subject to failure, and iPhones are no exception. If you find that the iPhone does not charge, do not draw unequivocal conclusions. The problem can be both serious and simple. You need to figure out what happened to your device and what caused the lack of battery charge. There can be several reasons. In this article we will review the main faults, as well as tell you what to do if your iPhone does not charge.

The first thing that comes to the mind of the user when he is faced with a problem. a faulty battery. This is partly true, but not always the cause lies in the battery of the device. If the problem is really caused by a faulty battery, you will encounter a number of other symptoms of failure: the device discharges quickly, does not hold a charge, restarts. The probability of a sudden battery failure is equal to one in a million. Here are the most common practical reasons why the iPhone does not charge.


Practice shows that problems with iPhone charging are often caused by a problem with the software (firmware glitch). There is a controller inside the device that is responsible for supplying electricity to the battery. The controller is operated by the device software. When the user connects the charger cable to the connector, the power to the battery is not supplied directly. First of all it goes to the board, which operates under the control of the program “protected” in the smartphone.

So, the power is supplied to the battery only after the software recognizes the current source and sends the appropriate command to the controller. After that the charging process begins. If the program fails, the command will not be sent. Consequently, the iPhone will not be able to charge. The problem is usually solved with a hard reset.

Defective Lightning

Why iPhone does not charge? Another possible cause is a defective or dirty Lightning port. The vast majority of users carry their devices in their s. This usually leads to the emergence of various malfunctions associated with the accumulation of various debris in the connectors of the device. Small particles are clogged in the charging port, compacted, and prevent the establishment of a tight contact between the plug and the pins of the connector.

Failed charger

If you use a non-original charger, you should consider buying an Apple device right now. That is, the reason why the smartphone battery does not charge, in this case is very clear. But what if the device does not charge through the original charger? It also happens in practice. Here it is worth saying that the “native” cable is quite fragile, so its failure is a matter of time. Its wear is accelerated by careless and sloppy handling. Kinks violate the integrity of not only the outer shell, but also the wires through which the current is supplied.

Worn out battery

The battery in your phone is a consumable item. Its life is limited by the number of charge and discharge cycles. Over time the battery loses its original capacity and ceases to please the former autonomy of the device. In fact it is an unavoidable process.

If your iPhone is over four years old and you haven’t changed the battery, it’s time to take it to a service center. Replacing the battery in your smartphone is not the most difficult thing. But requires experience, special tools at hand. So the right solution is to visit a specialized service center, where you will install a new original battery and provide a warranty.

Defective internal components

Another reason why iPhone doesn’t charge. It is the worn internal components of the smartphone. In addition to the battery can fail the power controller or charging. Only a full and qualified diagnostics of the device will help to accurately determine the breakage. According to the results of diagnostics in the service center specialists will offer you a rational method of solving the problem. Often this is either replacing the battery or replacing the controller.

iPhone doesn’t charge. the hardware reasons

Causes of iPhone not charging, but shows that it is charging are as follows:

  • Damage (breakage) of cable. If your cable has been damaged (physical wear and tear, animals, children, etc.) then you will not be able to charge your iPhone, and in some cases you will see signs of charging, but de facto it will not happen;
  • Broken charging port (Lightning). Usually caused by physical wear and tear, as well as strong (sudden) movements by the user when plugging and unplugging the cable;
  • Dirt clogging the port. During long-term use of the phone, staying it on various nap (dirty) surfaces, the jack can get clogged with small pieces of hair, dirt, dust, etc., which leads to poor contact between the cable plug and the port;
  • A problem with the charger. Your device for some reason (physical wear and tear or incomplete compliance with the declared characteristics) does not give the declared charging parameters (usually 5V and 1A), and this leads to various problems with charging your smartphone. Especially devices from little-known manufacturers (so-called “noname”) are guilty of this;
  • Problem with the battery (usually wear and tear). Over time, the battery has reached the end of its life and must be replaced. If you have been using your iPhone for a long time, or if you have bought it with your hands, then it is likely that the battery of your device has reached the end of its life;
  • Physical damage to the phone board. If your phone has received any physical damage, fallen or experienced any other mechanical effects, then it is quite possible they have negatively affected its functionality, including the ability to charge it;
  • Problems with the controller that charges the phone.

iPhone doesn’t charge. software reasons

Among the reasons why you can not charge your iPhone, there are software reasons, and some experts call them prevalent. The main software reason is the software malfunction (at the firmware level) that for some reason does not give charging commands to the phone controller and therefore charging simply does not happen.

Another reason why iPhone refuses to charge is the use of incorrect (custom) firmware (such firmware is available for the first generation iPhone, iPhone 3G and 3GS, iPhone 4, iPhone 4Rev A).

? The adapter is out of order

The original adapter for iPhone is an ancient and virtually indestructible accessory. But even it can simply break. But in this age of digital technology is not a problem to find another adapter in the apartment, not necessarily a brand-name. As long as the voltage is 5V and the current starting from 1A.

Solution: get another adapter with the same characteristics

Checking the charger

For starters, if the iPhone is charged in the off state only up to 4-20 percent, it is worth checking the charger on another device. It is quite possible that:

  • Broken wire in the cable. The current in this case is significantly reduced, not allowing you to charge the battery to the expected 100%.
  • The electronics in the charger unit is burned out, again, the current will be significantly reduced. Repair is powerless, you better buy a new charger for iPhone 6.
  • The lightning plug is loose or the chip on the cable is damaged (yes, yes, iPhone laces have chips).

Check whether the charger works, simple enough, take a working charger from friends / neighbors / lovers and connect to your unhappy device. iPhone happily beeped, informing about the receipt of energy in the battery, then run to get a new, preferably original charger.

It is possible to buy and Chinese, but not the cheapest, there is a chance you will get a quality product. But there is a high percentage that you get a counterfeit, for a lot of money, not able to fully charge the battery gadget. Among other things, fakes can disable the power controller of the device, and it is 100% getting to the service centers.

Clean the connector

You can try to clean the connector, it is often the reason why iPhone is booted and works only on charging. To do this, take a normal cotton swab and carefully, without fanaticism, clean the place where the plug lightning is connected.

Examine the cable

Now let’s take a closer look at the cable itself. It should not have bends and kinks, if they are present, try to change the wire, borrowing from a neighbor. In 80% of cases, the culprit is him, if so, you can safely send the cord in the trash, repairs are not advisable, even if it is an original accessory that comes with your phone.

The screen says “accessory is not supported or certified

  • Try reconnecting the cord the other way, sometimes it works.
  • The wire is broken or broken.
  • You neglected the advice to clean the plug.
  • You have a cheap Chinese knockoff, throw it away and go back to the store.

USB port Failure

And now admit how many users are used to charging their phone from a PC or laptop? I think there are a lot of them. And sometimes the source of the problem can be found in the USB port itself. For example, the port is broken or partially torn. This sometimes happens if you fail to yank its plugged in cord (though, yank it hard). Then it is obvious that the charging does not work because of the port.

For example, the case shown in the photo. The port is badly broken and can only be replaced. The bad news is that the laptop or PC needs to be taken to the repair shop. The good news is that if you have a free port, you can easily plug your iPhone cord into it. If the charging goes, the phone is fine.

Also, it’s important to remember that iPhones use specific voltages. And externally a whole USB may just not give enough voltage. The device needs 5V voltage and 1A amperage, and normally USB ports have 5V and 0.5A. This is not critical for competitors’ devices, they just need more time to charge. But the controller mentioned at the beginning will simply block charging at these voltages and currents.

Do THIS if your iPhone is not charging

We have considered the main reasons why a smartphone battery can stop taking a charge. But what to do if the iPhone does not charge? Below in order we will tell you about the ways of solving this problem.

Reboot the device

Almost all failures in the software of the device are solved by rebooting. First, reboot your smartphone in the usual way. If it does not work, perform a hard reset. Press and hold down both Power and Home buttons simultaneously for 30 seconds. The phone must go to restart after which it operates correctly.

Checking the charger

In case of careless use the original charger (cable) fails. Many people then buy a non-original set, and after a short period of time they notice that the battery does not charge. Try changing both the unit and the cable. For a start it is enough to get a new original cable. Breakage of one conductive “core” will be the cause of the problem. About 70% of the phone malfunctions are solved by changing the charger cable.

Testing the charger

Another way is to test the charger on another device. Statistically the breakage of charger accounts for about 10% of cases. Take another Apple device (tablet, smartphone), and check the operation of the charger. If the battery of the second device does not replenish the charge level, then the cause of the fault is obvious.

Checking the power supply

As a rule, there are no problems with the “cigarette lighter” in the car or the socket at home. Often users encounter difficulties in trying to charge their smartphone from the computer. When iPhone does not charge from a laptop, computer, make sure that it is supplied with current with the necessary force. New models of iPhone are sensitive in terms of speed of data exchange and power. They are charged through the USB 2 ports.0, 3.0.

Cleaning the connector

What else you can do yourself? At a minimum, inspect and read the Lightning connector. Arm yourself with a toothpick and gently clean the connector, extracting various debris from it. It can be crumbs, dust, etc. It is also advisable to blow out the connector. But for this task, use only a special blower with air. We do not recommend the use of cotton swabs soaked in alcohol.

Faulty battery

In some cases, the problem is the wear and tear of your phone’s battery. The resource of modern lithium batteries used in smartphones is about 2-3 years, with active use the battery life is reduced. Not surprisingly, if the battery of the same iPhone 5s, released 7 years ago, or an older Android device after years of use has noticeably worn out and lost its original properties.

Battery problems lead to the fact that when the phone is on, the battery runs down many times faster, and even if you connect the charger, the charge is not coming or is too slow, and the device is normally charged only when it is off.

You can check the health of the battery without special tools, there is a software for iOS and Android. Android also has a built-in battery checker, called by entering the USSD command ##4636## (under “Battery Info”). The same information can be found using the Battery app, for iOS there is a good utility BatteryCare, available in the App Store.

The charger is to blame

The second serious reason why the iPhone does not charge may be a faulty charger. In this case, there are different situations. Your device is new, but it won’t charge? Most likely you have had bad luck, and you found a defective charger. You just need to try another one for starters. If you hear a distinctive sound and see that your iPhone is charging, it is probably the charger cable. But this is not a problem, if the iPhone is under warranty service, the store will carry out a quality replacement in a timely manner. And if you’ve dropped your charger, or it’s wet, you might want to call in a professional to repair it. You may have to buy a new one to see how your iPhone charges again. But it is much cheaper financially than buying a new device.

So, to summarize. Your favorite iPhone isn’t charging? But that’s not a reason to worry. Examine it yourself first. Check that the plug is clean and undamaged. Explore also the charger. It should work flawlessly. The power supply and cord must also fit your particular model of gadget. If all of these conditions are met, but the device still does not charge, you will only be helped by specialists.
