Actually, this problem is very rare. As soon as you connect your smartphone / phone to the USB port of a computer or laptop, it immediately starts charging automatically. This is, so to speak, the norm. Even if you connect the device to the USB port of the TV, the smartphone will start charging in the same way. Yes, not as fast as from the mains, but it will charge. And yet, some users complain that when the device is connected, it does not even start charging. What's the matter?

If we were talking about tablets, it would be much easier to answer the question posed: this is due to the fact that some tablet models do not initially imply USB charging. The reason is simple: they use more power than they get from the USB port of a computer or laptop. This applies to large tablets, with much smaller smartphones there are no such restrictions, and therefore it is necessary to look for the reason.

Reboot the device

This is the first thing you should do with this kind of problem. If there is a failure in the software of the smartphone, it is the reboot that allows you to cope with it in most cases.

Reboot the gadget, reconnect it to the USB port and see if charging has started.

Cable inspection

It would seem, what could happen to the USB cable? It looks like new ... Yes, most of the time the USB cable really looks like new or, at least, is in excellent condition, but this does not mean that it functions normally. It is enough just to squeeze it once, for example, with a chair leg, so that it stops working.

By the way, it is easy to check this. Connect the USB cable with your phone to the wall charger and see if the device charges. If so, it's definitely not the cable.

By the way, even if the cable is working, but you have another one, try using it.

Cleaning the microUSB connector pins

Pay attention to the microUSB port on the smartphone itself. Perhaps dust has accumulated in it and the contacts need to be cleaned - the problem is in them.

In an amicable way, it is better to clean the contacts with an eraser, but they simply cannot crawl into such a small hole, so you can use a ratchet or a match with a cotton swab. And be extremely careful - one awkward movement and the microUSB port will be disabled. In this case, the phone will not charge at all.

Using other USB ports

Be sure to use a different USB port if present. It is possible that the current USB port is not supplied with energy, or there is not enough current, or it is completely out of order.

Lack of charging current

If there is not enough current, the smartphone will not charge from the USB port. However, like other devices.

Why is there a lack of current? The reasons may be different: lack of power in the USB port located on the front panel is a common problem, you must use the port located on the rear wall of the system unit; low-power motherboard circuits; component settings, etc.

microUSB port does not work

In this case, we are talking about the microUSB port of the smartphone. If it fails, then the device does not charge at all and there is only one way out - to change the part.

What if all else fails?

First, try connecting your smartphone with another computer or laptop to the USB port. If it does not charge in this case, the matter is probably in the device itself, but only a specialist can find out the true reason.

If it happens so that charging is in progress, but the smartphone does not charge, read the article. It describes all the problems and ways to solve them.

The main advantage of any smartphone, like any other mobile device, is to keep the battery charged for a long time. But you still need to recharge the gadget.

• Previously, companies producing such devices equipped mobile devices with special original connectors.
• It was possible to turn on the device for charging only into an outlet using a proprietary "charger" provided by the manufacturer.
• Now mobile devices are equipped with universal micro-USB connectors on Android devices and USB type C - on new gadgets with the latest versions of Android and iOS operating systems.
• This helped to make the use of the device simple for the user, the loss of the cable is no longer a problem, since the device can be charged from a PC. But what if, even with this charging method, it is not possible to add charge to the smartphone? Look for the answer further in the text.

Why is the Android phone and iPhone not being charged via USB from a computer, laptop, from charging from the mains?

If you connect a smartphone to charge from a computer or laptop, and the charging percentages do not increase, the reasons may be very different. Let's take a closer look. It is worth noting several main reasons why the Android phone and iPhone cannot be charged via USB from a computer, laptop, from charging from the mains. Let's consider them in more detail:

System glitch in the device program.

• If the OS is frozen, the controller does not give a command to transfer current to the battery.
• Getting rid of this problem is simple: restart your device by holding down the On / Off or Home key for a few seconds.
• Then turn on your device and connect to your computer for charging.

The problem is in the firmware.

• Often this problem occurs with iPhones. If you recently updated the firmware and suddenly the phone stopped charging, then roll back.
• But to complete this step, you need a backup that you should have made earlier.
• This recovery is done through iTunes. Just click in the program " Recover from copy».
• If you do not have a system in reserve, then reset to the manufacturer's settings. But please note that in this case you will lose all photos, music and video files.

Charger malfunction

• The charger can break down quickly, especially if it's Chinese and cheap.
• You need to charge expensive smartphones only with a proprietary block. The use of "left charging" can have the most unpleasant consequences: rapid battery wear, device breakdown, or even an unexpected explosion.
• Try connecting your device to your computer using a different cable.

Faulty Lightning cable

• Even if such a cable looks great on the outside, it may still be faulty.
• Try using a different cable of the same type. If charging is in progress, then there is a malfunction in the old cable and you need to buy a new one.

Lightning port glitch

• Often such a malfunction occurs with iPhones.
• This is not always just a breakdown. Dust and dirt can be the cause of the problem. This will be seen if you look into the port.
• If you can see that there is a lot of dust in the hole, then carefully remove the dirt from the port with a toothpick. The contacts will clear and begin to conduct current.

USB port is not functioning

• The USB port may not function in a PC or laptop, or there may be little current or power in it.
• Connect to a different port or charge your smartphone from a wall outlet or PowerBank.

Malfunction in parts (battery, loop and others)

• If you have already followed all the tips, but the phone still does not charge, then it has a faulty part.
• It so happens that water gets into the smartphone and it stops functioning normally.
• In this case, you need to take the device to the service of specialists. They will find the problem and fix the breakdown.

Lack of charging current

• You can find out with the help of a tester, usb-doctor or using a special program on your phone.
• If you can't do it yourself, contact your IT specialists for service.

Thin cable

• The wire may be too thin to conduct as much current as needed.
• Try using different wires with the charger instead of charging from the computer.

Low power in the motherboard circuit

• It is unlikely, but such cases do happen. Basically, manufacturers adhere to the standard, but such a malfunction must also be taken into account. If the manufacturer still does not declare the function of charging devices via the USB port, then you should not rely on powerful charging currents.
• Contact a professional if you suspect this problem.

Bus feeding

• If your computer is designed only to be switched on from the periphery, and not to power gadgets, the power may not be enough for charging.
• You should review the BIOS settings. But it's difficult to do it yourself. Contact a specialist.

If you are in doubt about the quality of your USB ports, you should purchase a dedicated charger cable tester. Its price is small (up to 250 rubles), but you can always find out if this is the cause of the malfunction.

The phone shows that charging is in progress, but not charging: what to do, how to charge?

When the mobile device does not charge, it is a grief for the user, especially if the charging is in progress and the battery remains at zero. In this case, panic begins, because a modern person without a telephone is like without hands. What to do and how to charge if the phone shows charging but not charging? Here are the possible causes of this problem and the ways out of situations:

• The charging block does not function. Try charging your device through a different wire and block. If it doesn’t help, then that’s not the problem.
• Faulty phone system... If you are sure that the wire and the charging block are working, and the smartphone says that charging is in progress, but the battery is at zero, then you should contact a specialist with the device. In this case, you need to flash the device or replace the input.
• The battery is out of order... The battery in the phone cannot be repaired, and if it malfunctions, you need to buy a new battery. If this part is built into a smartphone, then you will have to purchase a new device.
• Open applications and other services... If you put the device on charge and did not close the applications, and also did not turn off the services, then charging will go slowly, since the functioning of open programs is powered. Disable all applications, programs, services, and especially WI-FI.

It often happens that the phone is on charge for a long time, for example, all night, and the battery charge after that is scanty - 1-2%. In this case, the problem is in the defective battery or power controller. In the first case, you can replace the battery and continue using the device, and in the second, you need to bring the device to a professional for repairs.

Video: iPhone4 Shows Charging But Won't Charge. We repair the battery cable

Let's imagine this unusual situation. The user purchases a tablet, unpacks it and decides to charge it from the computer. Using a USB cable, he connects the device to a computer or laptop and ... Nothing happens. Generally. What's the matter, how to be in such a situation?

Lack of power

Some tablets simply do not have enough power to charge from the USB port. As a rule, this applies to models with large screens, since they consume a lot of energy, but, according to reviews, this disadvantage occurs on small tablets as well.

What to do? To accept it as a feature of the device, you still can't do anything about it. Charge your tablet from the mains.

By the way, if there is a lack of power, the tablet may show that it is charging from the USB port, but in fact it will not charge.

Reboot your tablet

If until now the tablet was charged from USB, and now does not want to, it may be a failure of the operating system. Which OS, computer or tablet? Just in case, we recommend that you restart the tablet first and, if that does not help, the computer.

By the way, try connecting the switched off tablet to the computer and see the effect, it often helps.

Use a different USB port

It is possible that the port you are using is having some problem, as a result of which it does not charge the tablet. Try to use a different USB port, fortunately, even on laptops there are at least 2-3 of them.

Check USB cable

This is especially true if you've pinched the cable or have pets that love to chew on wires. To test the wire itself, try charging the device with it from the mains. Not charging? Most likely, the point is in the wire, although we must not forget about the USB connector on the tablet itself, which could fail.

The phone does not charge from the computer - causes and solutions to the problem

One of the main advantages of a smartphone, like any other portable device (tablet, laptop, mp3 player, smart watch), is the ability to hold a charge for a long time. However, sooner or later you have to recharge the device.

The following instructions will show you how to fully charge your camera's battery. Chargers are available for purchase. ... In this case, it is recommended to turn off and turn off the camera. Here are some shots showing the preferred type of battery charging.

The electronics installed in the units determine how much current can flow during charging. The prerequisite for this, however, is that you have a charging cable with a suitable connection for your mobile phone. The cable and power supply can usually be disconnected from new chargers. Also in this case, customers can simply unplug the power from the cable and plug in another.

Not so long ago, manufacturers supplied their products with original connectors, and it was possible to connect them to an outlet or a PC only using a proprietary charger and cable. Fortunately, today almost all smartphones are equipped with a universal micro-USB port (most Android models) or USB type C (newer Android and iOS models).

If the voltage is out of specification, the smartphone simply won't charge. However, there are differences in the power output of the power supplies. This is from 2.5 to 10 watts. This corresponds to current intensities from 0.5 to 2 amperes. The following applies: the longer the power supply, the shorter the charging process.

Try different chargers yourself

Therefore, it may even be helpful to try power supplies from other manufacturers if you are unhappy with the charging speed of an included power supply. Many mobile phones do not often get maximum power from their own chargers.

Such universalization made life much easier for the user. Loss or breakdown of charging is no longer a significant problem - they are all interchangeable. In addition, it became possible to charge your devices directly from the computer USB ports, that is, you no longer need to carry a bulky power supply with you!

Some manufacturers even stopped putting a charger in the kit - just a USB cable and that's it. But what if the smartphone refuses to charge in such a convenient way? Let's list the possible causes of the problem and how to solve it.

The autonomy of today's mobile phones is not what is required and generally we have to boot our device every day if we want it to be fully functional. Either because we're in a hurry or for some other reason, we're going to give you some tips so you can charge your cell phone as quickly as possible.

Currently, the battery life of smartphones usually does not occur on the day of normal use. Manufacturers are trying to counter the limitations of existing batteries by programming economy modes with which we can deactivate functions or characteristics that consume the battery, but at some point we are not needed. Although in these saving modes we can extend the battery life in some cases, it may happen that we forgot to charge the mobile phone and we need to use it in a short time.

Why is the phone not charging from the computer via the USB port?

Let's first consider the options in which there is no reaction at all to the connection. That is, no messages appear on the screen of the computer and phone, and no corresponding sounds are played from the speakers. There may be several reasons for this.

The phone is charging, but very slowly

So, you have ruled out all the reasons listed above, but your smartphone stubbornly does not want to charge normally without a charger. That is, everything is in order with the connectors and cables, you can normally connect to the computer, and it even sees the smartphone, but the charge level practically does not increase or even decreases. Most likely, you are faced with one of two reasons.

Activate airplane mode or turn off the phone

It's as simple as activating the device's airplane mode to turn off all connections, which, by the way, consume a lot of battery. Another option is to turn off the device directly, since we will not turn on the screen, another of the sections that consume more battery.

Therefore, by activating airplane mode or turning off the screen, almost all or all of the power from the mains will be designed to charge the battery, which will shorten the charging time while increasing autonomy. We spoke to you recently and we see that using a copy can be dangerous for us. Even though there are original chargers that can get good performance, it is best to always use the original as it was developed by the same phone manufacturer and should know perfectly well how to supply power to the device.

Recently faced a problem. The phone is charged from USB using a native cable that is included, but does not charge from a similar Chinese one.

And a strange thing happens, the phone says that charging is in progress, but in fact nothing is being charged, the battery just sits down. Some kind of nonsense.

Typically, the copy has fewer components and less security, so in addition to not getting enough power and load more slowly, you may have significant security risks. If we can choose this option, the charging time can be reduced by 50%. To finish, just comment on two tips that strongly recommend keeping our battery in good condition and this will allow us to charge the battery 100% without slowing down the charging time. One is heat related, as it is very important that batteries are charged at room temperature and not exposed to excessive heat sources.

I googled - I am not the only one to have such a problem, both in Runet and on the Internet there are a couple of references to such a problem, though without a solution.

The first thought was that in the original cable there is a tricky tab, maybe some pull-up resistor bypassing the specifications, in order to inform the phone about the "originality" of the cable. I called, it was not confirmed.

This will allow us to extend battery life and avoid other complications. Finally, it is also advisable to perform battery maintenance tasks. This is what is commonly referred to as battery calibration and consists of charging the cell to 100% and discharging it completely until the device shuts down. To know for sure that the battery is fully charged, a good trick is to touch the charger and check that it is cold.

What are you doing to boot your devices faster? Of course, some of us find ourselves in a situation where our phone is running out of battery and we don't have a charger on hand, while desperate to stay in touch to answer an important call, receive a text message or receive an email. ...

Then, for some reason, I had the idea that the inductance of the cable was interfering, the phone quickly turns on charging, measures the voltage drop, is surprised at its strong drop and refuses to charge. To test this hypothesis, I opened the cable and planted a smoothing capacitance closer to the plug. The cable was thick, it inspired confidence, but it turned out that the insulation was so thick, the conductors themselves were thin.

Before we get to the issue of thieves, we must point out that not all chargers are as good for your smartphone. The internet is full of complaints, most of the users who have tried to charge their expensive phones with non-original chargers or adapters. In some cases, the phone ended up as an expensive paperweight. At times, it is already very strange, the people who were holding his phone were seriously injured or even died.

Unfortunately, these may not be just accidents. We doubt that you want to test the longevity of your phone using this method. Locking your phone will save you the trouble of being exposed, but are you seriously stopping it from using it when you charge it?

I soldered it, checked it - it didn't help.

Then I wandered out on this topic. User Rob gave interesting data:

SONY ERICSSON W 810i - - - - BST-36 battery, on the original BST-37 the currents are almost exactly 2 times higher. - 4.4 v - 0.0ma / tel does not see a charge 4.6 v - 0.0ma / the indicator is already with lightning, that is, it sees a charge, but in fact the charge current is 0. 4.8 v - 50.5ma / OOO It takes a very long time to charge 5.0 v - 107.8ma /. ... 5.2 v - 110.0 ma / current almost did not increase 5.4 v - 180 ma 5.6 v - 225 ma 5.8 v - 240 ma 6.0 v - 270 ma 6.2 v - 340 ma 6.4 v - 500 ma 6.6 v - 0.01 ma / tel goes into failure - "charge error! Not standard charger, stop charging immediately!"

The size of the data varies depending on the platform of the phone and the operating system of the host system, but in any case, not only is it loaded but also found to be carrying data such as device name, provider name, and serial number. Of course, you think that there is no problem with the transfer of data, but there is because after analyzing the public information of a particular operator, we saw that much more is allowed than indicated in the system.

You can also make calls to any number and if you are roaming these calls can leave you red very quickly. Depending on your carrier, this mode also allows you to instantly access any type of application, including malware.

I measured the voltage at the connector under load - 4.46 V. At the same time, the charging has 4.96 V. I measured the resistance of the wire - 2.2 ohms! The original cable has a resistance of about 0.3 ohms. Bingo!

The picture is the following - the Chinese saved on copper and put thin conductors in the cable. This does not interfere with the transfer of data and the operation of most devices, but when you try to charge through a cable (Maximum current from one USB port according to the standard 500 mA), the voltage U = I * R begins to drop on the resistance of the wire. As a result, instead of the required 5V, 4.46V comes on the phone, from which the electronics behave in such a strange way.

All of the above is possible even when the smartphone is locked! You will never know this before connecting your device, so don't do it. We recommend that you charge the battery before using it. If the battery is completely discharged, it may take several minutes to start.

Select a configuration option: compatible computer or mobile device

Batteries for detailed battery information, battery life and small battery notifications. Both methods require an internet connection. Everything is ready to start, have fun!

What are the dangers of charging your mobile phone in public places?

At an airport, in a bar, or in a rental car that connects the ports available to charge your smartphone's battery, the security of your personal data can be compromised.

I cut the wire and shortened it to 10 cm, to carry it as an adapter in a backpack. Shortened to 10 cm, the charge went great.

The rapid loss of charge on communication facilities causes serious inconvenience to the owners. If your mobile phone is not charging, you can always find the cause of the malfunction and correct the situation. And in cases where the mobile phone is not charged either from charging or from the USB port, it is recommended to contact a workshop for repair or replacement of individual parts.

Mobile phone does not charge

When the phone does not charge, you have to deny yourself many familiar entertainments: calling friends, watching clips, visiting your favorite sites. The estimated lifespan of modern batteries rarely exceeds two years, and the first symptom that heralds a quick replacement of this part is too fast a phone discharge and charging problems.

There are several options for a malfunction. In some cases, the device does not charge from a charger, in others - from USB, in others - it shows the battery charging process on the screen, but in the end it turns out to be only 10-20% charged. Many owners immediately purchase a new battery, but do not rush: in some cases, the battery can last for a long time, and the cause of the malfunction lies in the connector, charger cord, or oxidized contacts.

Phone shows charging but won't charge

If, when connected to a power source, the phone shows charging, but does not charge, the first step is to check which applications are running at that moment. Perhaps you forgot to turn off your mobile internet, Wi-Fi or game. In this case, the device may consume more energy than it receives when charging, especially when using the USB port. When charging is in progress, but the phone is not charging, the reason may be a non-original charger. Cheap copies from China can seriously harm the battery, and the charging process turns into a lottery with unpredictable results. Therefore, it is much more profitable to purchase an original charger with which you can power your mobile at any time. If you are using a quality device, then the failure may be due to a partial violation of the integrity of the cable. Internal damage can be invisible, so there is only one way to check - take a different charger.

My phone won't charge via USB

Owners of laptops and computers often combine business with pleasure: they use the USB port to charge the phone. However, it may well happen that this method will only bring disappointment. The phone does not charge from USB in several cases:

• the connector is too loose;
• oxidation of contacts has occurred;
• the wire is broken;
• the battery has become unusable;
• battery is incorrectly calibrated.

If your phone won't charge via USB, try feeding it with a power outlet. For this purpose, it is worth using a charger recommended by the manufacturer, and if you do not have one, an adapter. The process will go much faster.

Sometimes connecting to a different port can help, because the inputs of the laptop or computer may also be faulty. And sometimes the cause of the problem is inattention: if you do not fully insert either of the two ends of the cable, the phone will not be able to charge, since contact is not provided.

Notebook owners are also advised to check that the laptop is connected to an electrical outlet. If the device is running on battery power, the system will often block the use of the USB ports. As long as you have at least one way to recharge your phone's battery, don't worry. However, it is important to constantly monitor the condition of the battery itself and not use it at the slightest sign of deformation.

Why does not it charge - the main reasons

Is it possible to independently determine why the battery on the phone is not charging? If you decide not to contact the master yet, you can exclude several potential causes of the malfunction yourself. To determine why the battery on your phone is not charging, take a close look at the connector. If the owner has a habit of leaving the smartphone on charge overnight, sometimes you may notice a color change in the connector area. This may indicate that it regularly overheated, so it is possible that the contacts have oxidized or deformed. In such cases, it is advised to very carefully wipe them with alcohol.

The next step is to inspect the battery. Bloating can be detected by placing the battery on a table and twisting it. A serviceable battery adheres tightly to the surface so that rotation will not occur. A defective one will rotate easily. As soon as there are irregularities in the shape of the battery, it should be replaced immediately: it will still not be possible to fully charge the device. And with further use, the battery case may crack, the contents will fall on the board, and then the mobile will only have to be thrown away.

Doesn't charge - what to do

A battery charging problem can arise at any time. What to do if the phone won't charge? To get started, try charging the device while it is off and make it one of your habits. In case of failure, experts recommend contacting friends with the same cell phone model and try to use their charger or cord to connect to a computer. If this operation is successful, buy yourself a new charger and cord.

If your device does not charge from someone else's charging, then you will need the help of a qualified specialist. The foremen have all the necessary parts and equipment to find the cause of the problem and repair the power circuit, connector or phone battery controller that does not charge.

It should be noted that the phone battery is not repaired: this part will have to be replaced. It is worth giving preference to original spare parts, because they are ideally suited to the needs of a particular model.
