Why is charging going on but the phone is not charging? These include. Why your smartphone won't charge: probable causes of failure

Why isn't my phone charging? Possible causes, diagnostic instructions, self-repair. When to contact the service center.

Your phone isn't charging? So what, it’s a small problem. You still have a functional device in your hands, which just decided to play around. The main thing is not to panic, find out, at least quickly, the cause of the malfunction and fix it immediately. Don't know how to do this? Then you have come to the right address. We'll tell you why your phone won't charge and what you can do about it at home.

Why is my phone not charging?

The phone does not charge for only one reason - the device’s battery cannot receive energy from the outlet. Simply put: some obstacle has appeared in the path of electricity, breaking the power circuit. And this obstacle could be:

  • Cable or charger. The first may refuse to conduct current, and the second may simply break and not supply voltage to the cable.
  • A phone connector that easily becomes clogged with dust and other debris that interferes with normal contact between the cable connector and the smartphone port.
  • Phone or battery board, or rather controllers that monitor the charge level.
    A worn-out battery that is unable to hold the required amount of charge.

Now that you understand why the phone is not charging, all that remains is to find out how to eliminate this or that obstacle.

Cable and charging problems and how to fix them

This problem is usually encountered by owners of old devices. Over the course of a long and faithful service, both the charging and the cable itself may wear out. Moreover, this failure is diagnosed very simply: the user inserts the charger into the socket, connects the phone to the cable and sees that it does not even think about charging.

What to do in this case:

  • First, remove the cable and connect it to the USB port of your computer. If your smartphone starts charging, then you need a new charger.
  • Secondly, try charging your smartphone using a new cable. If your phone battery shows signs of life, you will have to throw away the old cable.

At the same time, do not forget that a new charger can bring another problem into the house - a loss of charging speed. This usually happens when, instead of an original and expensive charger, they buy something more affordable. And if your smartphone charges slowly after replacing the charger, then you are better off replacing the current charger with a branded module. The fact is that some chargers can generate significantly more voltage (and current) than a regular USB port.

By the way, it happens that the iPhone does not charge due to the absence of a chip in the cable. Cunning Apple engineers came up with a mechanism for identifying peripherals, including chargers, using a special chip, installation of which is possible only with the consent of the Apple corporation. Therefore, non-original cables and chargers without a chip simply will not be perceived as functional by the phone itself.

Solving problems with the connector

If you have changed both the charger and the cable, but there is still no use, then the obstacle is most likely the phone port. What to do in this case:

  • Unplug the charger and turn off the phone.
  • Remove the battery and turn on a bright desk lamp.
  • Hold the connector up to the light and examine it carefully. Usually a lot of debris gets into the phone port and you will have to remove it using a needle, toothpick and syringe.

The first tools can be used to pry up pieces of debris and pull them out. A syringe with alcohol will be useful if you need to wash out deposits of dust and dirt in the connector. In this case, alcohol is simply injected into the contact area of ​​the connector under pressure.

After rinsing the port with alcohol and gently cleaning it with a needle or toothpick, you can replace the battery and try to charge the phone again.

Problems with the board and battery

Have you changed the cable and cleaned the port, but your phone still doesn't work? In this case, you will face a more serious breakdown. Usually, if the smartphone battery does not charge, and the cable and port are 100 percent working, the source of the problem will be the smartphone board or battery.

And if you checked the cable on another smartphone, and the phone’s port allows data transfer (synchronization with a computer works), then your device will have to be taken to a service center. This problem cannot be solved at home. Maybe just try resetting the settings using the “reboot” button or a combination of “hot keys” pressed at the start. But even in this case, you will not have any guarantees to restore the charging process.

If Android is not charging, then the cause of the problem should be looked for in the power source, battery status and operating system (OS). Depending on the conditions in which the Android does not charge to 100%, the troubleshooting methods will change.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Android won't charge due to problem with power supplies

The first thing to do if your Android is not charging is to make sure that the charger and power source are working properly. If current is supplied to the battery from the outlet, check that it is working properly. If you connected your phone to USB, make sure the port is connected and working.

When charging through a computer or laptop, a completely discharged phone may not turn on. This is due to a lack of current power. Sometimes it even happens that the device does not charge, but discharges, because it spends more energy than it receives.


Lack of power may be due to the characteristics of the motherboard, system port settings, or a faulty cable. To avoid guesswork, buy an adapter and charge your phone from a known-good outlet. Mains power is the most correct way to fully charge the battery.

External battery and wireless charging

If the phone does not charge from an external battery, then the first thing you should do is make sure that it is the PowerBank that is to blame, and not the phone or a damaged cable. Problems with an external battery can be different:

  • The battery is filling, but not completely.
  • Charging is slow.
  • The device does not charge at all.

If the battery starts to charge, but suddenly charging is interrupted, then it is quite possible that the PowerBank has a capacity less than stated. Low-quality Chinese batteries can generally work like a capacitor: with the same mass, they accumulate tens of times less energy.

It is necessary to use an external battery, the volume of which is actually 2 times larger than the battery capacity of a smartphone or tablet.

When charging slowly, you should pay attention to the output current (a modern smartphone or tablet requires at least 1.5A), as well as the thickness of the cable. A cable that is too thin will reduce the current and voltage, so it is recommended to use original accessories for the phone/tablet rather than the cables included in the kit.

The charging speed is also affected by running “heavy” applications. If you connect several devices to the PowerBank at the same time, the charging speed will drop noticeably. Therefore, charge your gadgets one at a time. In addition, when charging is slow, it would be useful to calibrate the external battery and the phone battery.

If your Android phone does not charge at all from an external battery, then you should make sure that the equipment is compatible. If the Power Bank accumulates energy, flashes, shows that charging is in progress, but does not charge the phone, connect another device to it. If it starts charging, then you should buy another external battery for your phone.

Doesn't charge wirelessly

If problems occur when using wireless charging, first make sure that your phone supports this technology. Besides:

  • Reboot your device. The problem may be due to a minor system glitch or a bug in an application.
  • Boot into safe mode and see if it charges.
  • Remove protective covers and other accessories that may be in the way.
  • Replace the cable of the charger itself with a thicker and shorter one.

Use only original accessories that are exactly compatible with your specific phone or tablet model.

Hardware and software problems

If everything is in order with the power supplies, and other devices are charging normally from them, then proceed to diagnosing the smartphone/tablet. But first, check the charger again. It should be:

  • Original, that is, fully compatible.
  • In good working order: no creases or damage.

Then you can begin an external inspection of the device. Make sure that the charging socket is not loose, but is tightly connected to the smartphone board. Check the condition of the contacts. If they are dirty or show signs of oxidation, clean the contacts using a can of compressed air, alcohol and a fine needle or toothpick. You have to be careful not to damage your smartphone.

If traces of mechanical stress are visible on the case, the phone has been exposed to extreme temperatures or has been in liquid, traces of which remain inside, then it is recommended not to try to fix the problem yourself, but to immediately contact a service center.

If nothing bad happened to the device, try rebooting it or resetting it to its factory state, after making a backup copy. If the phone charges only after a reboot, and this problem appeared after flashing the firmware, then you should reflash the device from scratch. Installing non-original firmware or errors during flashing may result in the device not charging, even if the battery is working.

Battery calibration on Android

What should I do if my phone doesn't fully charge when it's turned on? The screen flashes that the device is fully charged, but within a few minutes after disconnecting from the network, the charge level drops by 10-15%? Such problems do not happen with a new battery, but if you have been using a smartphone for a long time, then this is a fairly common situation. To perform a manual calibration:


Instead of manual calibration, you can use special applications - for example, Battery Callibration. To perform calibration.

Ragged or ground The wire is one of the most common reasons for lack of charging when connecting the phone to a charger or computer.

How avoid damage wires:


What to do if the cable is already damaged or torn:


  • The simplest and most expensive way to fix a breakdown is buying a new one wires.

The phone connector is damaged

An equally common problem is connector failure on mobile phones. Detecting such a breakdown is not very easy, but it is possible. One of the characteristic signs of a connector malfunction is inclusion charging only in certain positions of the cable plug.

How to fix the problem:

  • The first thing to try is clean charging connector. Accumulated dirt often causes many breakdowns;

Bad battery

Battery problems can also make it impossible to properly charge a cell phone, smartphone, tablet, or other device. It could be Battery swelling, burnout contacts or simply a loss containers due to aging.

There is only one way to fix this problem - acquisition And installation new battery. You need to buy a battery exclusively for your phone model, and it is recommended to choose original products, because cheap Chinese analogues can be much inferior in quality and capacity.

Software problems

Errors While software problems often occur in smartphones, malfunctions of this kind very rarely occur on regular mobile phones. Software failures include firmware faults device, drivers as well as installation malicious applications that prevent the device from charging correctly.

Ordinary users can try to correct errors in software in two ways: reset settings on your smartphone or flashing device.

How reset settings:

If the smartphone does not work due to lack of charge or absence reactions Resetting the settings will require a full flashing device. The firmware process depends on the specific mobile phone model; on some, it is enough to download special software and connect the smartphone to the PC. Others will require advance unlock bootloader or enter the device into the firmware menu. Inexperienced users should not do this on their own; it is better to turn to professionals.

Battery not calibrated

This problem may occur during installation new battery to the phone. This may manifest itself in the following ways: no response to connecting the charger, the phone is not fully charged or discharges quickly. To calibrate the battery, you need to carry out a couple of complete charging and discharging cycles of the phone.

After reading our article, even those who are not particularly comfortable with technology will be able to figure out a little what’s what. Simple but miraculous recommendations will make the naive - wise, and the defenseless and insecure - experienced experts in the question: “What to do if the phone does not charge?” Most likely, even people who are not technically savvy will be able to adequately answer the presumptuous “guru” from an independent workshop that the cause of the malfunction lies not in the red button or even in the fact that the beloved dog likes to play with the dangling cord of the charger. After all, everything that can be done at home will be known to you, and believe me, this is not little. Let's discard the lyrics and move from words to practice.

Why the phone does not charge: the main reasons and methods for eliminating them

As a rule, such a malfunction occurs as a result of mechanical or chemical influence. However, a software failure of the mobile device cannot be discounted. Even such a modern phenomenon as “electronic infection with malicious code” can cause problems in the power supply system of a smartphone. Nevertheless, a correctly performed diagnosis will dot all the i’s.

Is yours working properly?

If your phone stops charging, you should first visually inspect the power cord. You may find obvious signs of damage to the outer insulation of the cable. Deformation in the form of kinks and stretching should also not hide from your view. If everything is fine with the wire, and the plug has not oxidized, ask your neighbors, friends or co-worker for help, maybe one of them has exactly the same charger. Positive result - go to the store and buy a new charger, no - we move on.

As an addition: USB check

As a rule, a mobile device purchased in a store comes with a synchronization cord (DATA cable). Connect your cellular device to your computer. via USB?

Disconnect everything from your PC. No reaction? It’s a bad situation, but it’s too early to get upset; there are several other methods with which you can try to restore the “energy life” of your mobile phone.

Software failure and what the virus is capable of

Often, smartphone owners sin by installing various programs and applications that expand the capabilities of the device. Moreover, without even thinking about the “decency” of the developers and without attaching importance to the nuance that the distribution source is filled with extremely dubious content. As a result, the working firmware begins to glitch. The charge indicator may stop working altogether, and if a virus has taken root, the phone will quickly lose the battery charge that once held for two or three days. Pay attention to whether any of the wireless modules turn on spontaneously. If you find a problem, remove the program and neutralize the malicious code.

mobile device

Remember: never panic when deciding on the question “what to do if your phone won’t charge”: this can always be fixed.

In bright light (and if you have a magnifying glass, it's absolutely wonderful) inspect the inside of the nest. “Chic and shine” is a great sign! Contamination and chemical deposits in the form of oxidation require cleaning.

Remember the saying “the further into the forest, the more firewood”? So, do not try to forcefully pick at the narrow channel of the contact connector with various improvised means - you can still damage the entire system element. Caution, a thin brush and alcohol are all you need in this case.

A good solution to the question “What to do if your phone won’t charge” is a simple experiment. Insert a known-good charger into the connector of your mobile device and, without any obvious effort, shake the plug in different directions every second. The display comes to life - go to the workshop, “deaf” - read the next paragraph.

Accumulator battery

If the battery's energy reserve is completely depleted, it is likely that the autonomous battery has lost its starting impulse. In such a situation, you simply cannot do without a universal memory.

  • Place the battery in the clamp and, observing the polarity, apply electricity to the plus and minus contacts.
  • In just 5-10 minutes the battery can be inserted into the phone.

If everything is to no avail and a miracle does not happen, then the next stage of the “what to do if the phone does not charge” project will be a trip to the nearest workshop or service center.

Natural ending

Falling your phone and hitting it on a hard surface, even when it is shockproof “from birth,” does not lead to anything good. As they say, luck is temporary. As a result of this kind of mechanical damage, the owner of a mobile device may encounter the following problem: the phone does not charge - it is charging. Often, due to a strong impact, a mobile phone battery fails. The visually observable indication is actually just software graphics, which, in fact, work in vain. Since the battery tanks are not refilled. There are two options: either repair the power controller of the cellular device or replace the battery. In the first case, you simply cannot do without craftsmen.

Finally

Let's hope that the question of why the phone won't charge has been resolved for you today. Nevertheless, I would like to give you a few recommendations as an encouragement for your curiosity:

  • Don't use too often
  • Do not allow the battery to be deeply discharged to zero.
  • Do not leave your phone in the heat or, conversely, in the cold.
  • Install anti-virus protection on your phone (if the software allows it).

Have a nice day and successful renovation!

    By the way, this is not a rare situation at all. I myself have encountered such an incident several times and there was only one way out - to change something, either the charger or the phone. Most often, the contacts of the USB connector on the phone are covered, and most manufacturers now use this charging principle. It's no secret that all devices are equipped with protective curtains. But due to our frivolity, we always forget to close them and dust - the main enemy of thin contacts - simply gets stuffed into this compartment.

    If the charger burns out, then everything is simple - change it and that’s it. We perform a similar action with the phone battery. If there is a software failure, you need to take the device in for repairs, and it’s good if it’s still under warranty.

    The cause of the malfunction is determined by sequentially replacing the charger, battery, charging source - network or computer, and flashing the phone. It is better to entrust the last operation to professionals; I personally did this.

    There’s nothing to think about here - either the phone’s connector is broken, or the problem is in the charging itself. The best solution is to put another phone on the same charger. If the second phone does not charge, then the problem is in the charger itself. Otherwise, if the second phone is charging, the problem is with the first phone. So you either need to buy a new phone or take it in for inspection. There are no other options. Because it’s one thing when the headphone jack is broken (this is tolerable) and quite another thing when the connector for the charger is broken.

    Several options are possible. Sometimes the phone is charging, but the indicator shows zero level. In this case, rebooting the phone helps. Usually the indicator then begins to increase the phone's charge. If rebooting does not help, then most likely the problem is in the contacts, they are moving away. You can either carefully disassemble the phone yourself and check the connection of the contacts, or take it to a service center and they will fix it for you.

    As already written, the reasons may be different. Such as, for example, a malfunction in the phone itself, a malfunction in the charger or in the socket itself. I had a situation where the phone was not charging, the socket and charger were fine. After a detailed study of the charging connector on the phone, I saw that one of the contacts on the board was bent, I straightened it with a needle and the phone began to charge. But in the end it didn’t work for long, because at one point this contact fell off.

    Or the charging input has become loose, or the cause may be a loose contact in the phone at the charging input, or the cause may be a faulty or exhausted battery in your phone.

    The problem is in the phone itself or in the charger. First of all, check the integrity of the charger cable. In order not to give your phone directly to the service, ask one of your friends for the same charger and check whether it will charge the phone. If not, then the problem is in the phone itself.

    If the phone is charging, but is not charging, then this is most likely a breakdown of the charging cord, the phone's charging socket, or the reason is the phone's battery. It may also be that charging is from the wrong model or the wrong current and other parameters. It may also be that the battery is simply fully charged and does not show charging.

    There may be several reasons:

    1) The microcircuit that is located in the case of the battery itself has burned out, which is why no power is supplied from the charger. Failure of the battery itself is unlikely, since the charge should have been held. It may not be long, but 15 minutes would be enough. It can be checked simply by replacing the battery.

    2) The power stabilization chip in the phone itself burned out. That is, simply, the current does not flow from the charger to the battery itself. They will be checked, without lack of skills, at a service center or by replacing and purchasing a new phone (-; .

    3) Well, probably the last thing, the charger itself is not working or it was replaced with a weaker one in terms of current and voltage. Voltage, in principle, is of little importance; it will just take longer to charge and that’s all.

    True, conclusions can already be drawn by replacing the battery (battery) and charging it to 100% working. Further depending on the circumstances.

    There could be three reasons

    The first charger is inoperative.

    The second reason is the phone battery is not working.

    The third reason is that the charging connector is not working; you should take the phone to a technician.

  • There can be several reasons for this fairly common problem:

    • often the problem lies in the charging socket where the power cord is inserted (over time it becomes loose, the contacts no longer oxidize as they should, as a result of which they conduct electricity poorly or do not conduct it at all);
    • the problem may also be in the charger (by the way, the indicator may show that the smartphone is charging, but in fact the phone will not charge);
    • the electronic components of the device may fail, the battery may be damaged and/or deteriorated;
    • The outlet itself may not work, but this is very easy to check - in all of the above cases, it is recommended to contact a service center, where they will diagnose, identify the problem and eliminate it.
