USB does not charge the phone. Why is the phone not charging from the computer via USB and what should I do? What if the USB port stopped working after charging

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

One of the main advantages of a smartphone, like any other portable device (tablet, laptop, mp3 player, smart watch) is the ability to keep charging 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 disable and turn off the camera. Here are some shots showing the preferred type of battery charging.

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

Not so long ago, manufacturers supplied their products with original connectors, and they could only be connected to a power outlet or PC using a proprietary charger and cable. Fortunately, today almost all smartphones are equipped with a universal micro-USB port (most models on Android) or USB type C (new models on Android and iOS).

If the voltage is outside the specifications, the smartphone simply does not charge. However, there are differences in the output power of 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 useful to try power supplies from other manufacturers if you are unhappy with the charging speed of the included power supply. Many mobile phones do not often get maximum power from their own chargers.

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

Some manufacturers even stopped putting the 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 possible reasons problems and ways to solve them.

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

Nowadays, smartphone battery autonomy 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 features or characteristics that consume the battery, but at some point we are not needed. Although in these economy modes we can extend the time 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 us first consider the options in which there is no reaction to the connection at all. That is, messages do not appear on the screen of the computer and phone, and the corresponding sounds are not reproduced from the speakers. There may be several reasons for this.

Phone is charging but very slowly

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

Activate airplane mode or turn off your 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 partitions that consume more battery.

Therefore, by activating the flight mode or turning off the screen, almost all or all of the power from the network will be designed to charge the battery, which will reduce 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's best to always use the original as it was designed by the same phone manufacturer and should know perfectly well how to supply power to the device.

Recently ran into a problem. The phone is charged from USB using a native cable, which is included, but it is not charged from a similar Chinese one.

Moreover, a strange thing happens, the phone writes that charging is in progress, but in fact nothing is charging, the battery just sits down. What a nonsense.

Usually the copy has fewer components and less security, so in addition to not getting enough power and slower load, 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 the two tips that strongly recommend keeping our battery in good condition and this will allow us to charge the battery to 100% without slowing down the charging time. One of these has to do with heat, as it is very important that batteries are charged at room temperature and not exposed to sources of excessive heat.

I googled - I’m not the only one with such a problem, and 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 the original cable has a tricky tab, maybe some kind of pull-up resistor, bypassing the specifications, in order to tell the phone about the "originality" of the cable. Called, no confirmation.

This will allow us to extend battery life and avoid other complications. Finally, it is also wise to perform battery maintenance tasks. This is what is commonly referred to as battery calibration and consists of charging the cell to 100% and completely draining it until the device turns off. 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 have found ourselves in the situation where our phone runs out of battery and we don't have a charger handy, and at the same time with a desperate need to stay connected to answer an important call, receive a text message or email. .

Further, for some reason, I had the idea that the inductance of the cable interferes, 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 is thick, inspires confidence, but it turned out that this insulation is so thick, the conductors themselves are thin.

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

Unfortunately, these may not be just accidents. We doubt you want to test your phone's durability with this method. Locking your phone will save you from being exposed, but are you seriously preventing it from being used when you charge it?

Soldered, checked - did not help.

Then I turned to this topic. User Rob provided some interesting information:

SONY ERICSSON W 810i - - - - Battery BST-36, on the original BST-37 currents are almost exactly 2 times more. - 4.4 v - 0.0ma / the body does not see the charge 4.6 v - 0.0ma / the indicator is already with lightning, that is, it sees the charge, but in fact the charge current is 0. 4.8 v - 50.5ma / 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 - "Charging error! Not a 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 downloaded, but it is also found that they transfer 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 send calls to any number, and if you're roaming, those calls can leave you red very quickly. Depending on your carrier, this mode also allows you to instantly access any type of application, including malicious ones.

I measured the voltage at the connector under load - 4.46 V. At the same time, the charge was 4.96V. 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 this - 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 the cable (Maximum current from one USB port according to the standard 500 mA), the voltage U = I * R starts to drop on the resistance of the wire. As a result, instead of the prescribed 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 about it before you connect 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 up.

Choose a configuration option: compatible PC 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 is the danger of charging your mobile phone in public places

At an airport, a bar, or a rental car connecting 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, charging went well.

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

How avoid damage wires:

What to do if the cable is already damaged or broken off:

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

Phone jack damaged

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

How to fix the problem:

• The first thing to try clean charging socket. The accumulated dirt often causes many breakdowns;

Bad battery

Battery performance issues can also prevent your mobile phone, smartphone, tablet, or other device from charging properly. It could be battery swelling, burnout contacts or just loss capacity 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 exactly original products, because cheap Chinese counterparts can be much inferior in quality and capacity.

Problems in the software

Mistakes in software often occur in smartphones, on conventional mobile phones, malfunctions of this kind are very rare. Software failures include firmware malfunctions device, drivers as well as installation malicious applications that interfere with the correct charging of the device.

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

How reset settings:

If the smartphone is not working due to no charge or lack reactions Resetting the settings will require a full flashing device. The firmware process depends on the specific model mobile phone, on some it is enough to download special software and connect your smartphone to a PC. Others require prior unlock bootloader or enter the device in 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 when installing new battery into the phone. It may appear in the following ways: no reaction to the connection of the charger, the phone is not fully charged or the discharge is fast. To calibrate the battery, you need to spend a couple of complete cycles of charging and discharging the phone.

Many users, when trying to connect their phone to a computer using a USB cable, are faced with the fact that the computer does not recognize the connected gadget. The connected device is charging, while there is no access to the smartphone itself and its internal content. I also encountered this synchronization problem, and in this article I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving this issue.

The whole complex of reasons for the problem that the PC does not see the smartphone through the USB cable, I would divide into hardware and software, and below I will list each of them, in parallel providing instructions for fixing it. But before using the methods I have indicated, try restarting your computer and smartphone - this does not help as rarely as it seems. This problem mainly occurs with Samsung, Lenovo, HTC, LG, and Fly devices.

So why does the computer not see the phone via USB, but is charging - hardware reasons

1. Damaged cableUSB. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables from little-known or "non-name" manufacturers do not have a large margin of safety, and can fail in just a couple of months from the start of operation, and as a result, the computer will not detect the connected phone.

In addition, even the most reliable cables from global brands are prone to stochastic damage - they can be accidentally damaged during use, pets can chew them or spoil them by children. Therefore, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the external safety of the cable, try using it to connect your device to another computer. If the device is not recognized on another PC, try replacing the cord.

2. Damaged portUSBon the computer. The USB ports used in the computer are also subject to various mechanical damage, including damage to the USB controller, as well as damage to the south bridge. motherboard. Try plugging the cable into a different USB port, if that doesn't fix the connection between your phone and PC, follow the further advice.

3. Damaged socket for connecting the cable on the phone. Has the smartphone jack been exposed to water or damaged? If yes, then it needs to be replaced.

4. Try removing the battery. According to some users who also had a problem with the fact that the computer did not see the phone through U-ES-BI, removing the battery from the smartphone helped.

Turn off the battery, remove the battery from it for a few seconds, then put it back, and turn your device back on.

If nothing helps you fix this problem, then describe your situation. What have you already done and what is happening to your Android device when connecting the gadget to a PC via USB in the comments, I will try to help not only me, but also everyone who has encountered this problem.

The computer does not see the phone via USB - software reasons

After describing the hardware reasons, we list the main software reasons if your computer still does not recognize cellular telephone connected with via USB cable, follow the instructions below.

1. Working with the settings.We go into the settings of our device, select “Memory” there, click on the three dots at the top (Properties), select “USB connection to a computer” and check the box next to “Media device” (“USB drive”). If you have a checkmark next to using USB as a modem, uncheck it.

The Windows Update service (for downloading drivers for the phone) and the New Device Discovery service must be enabled on the PC. Don't forget to unlock your phone when connected to your computer, this is important.

If you are a conservative and have Windows XP installed, download the Media Transfer Protocol (MTP) for XP from the Microsoft website and install it on your computer.

2. If your drivers have crashedUSB-ports, the computer may not see the phone.When drivers for USB ports malfunction, the latter simply stop working. To fix this problem, install the USB drivers from the "native" driver disk to your PC motherboard, or download the latest drivers from the motherboard manufacturer's website.

Also, due to any reason, power can be turned off for a number of ports.

3. Device drivers have crashed. Go to the "Device Manager" and see if there is a question or exclamation mark in the "Portable devices" item.

Check if your device is there and make sure it works fine by right-clicking on it and clicking "Properties". If it's not there, or if you're in doubt, uninstall the driver, disconnect your phone from the computer, and then turn it back on, and let the system install the driver again. This can help solve the problem that the smartphone does not connect via USB to the computer.

It will also not be superfluous to enter the website of the manufacturer of your smartphone and download the latest drivers for it on your PC (for example, there is a special Samsung Kies software for Samsung).

4. Install the updateKB3010081 (KB3099229). For owners of Windows 10, you may need to install update KB3010081, which is responsible for working with Windows Media Player. This player is directly related to the normal operation of the MTP (Media Transfer Protocol) service, so download and install these updates.

Also, a common cause may be an unreliable assembly of the OS itself on the PC. Only rearranging Windows with a more working version will help here.

5. Custom firmware is not working. The desire of many fans to play around with firmware for their Android device can do them a disservice in the form of a device failure to work normally with a computer. Try to restore the standard firmware or restore from a backup (if any).

There are no drivers for the phone on the computer

Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, reverse cases can also be observed. Try to search for a driver for your smartphone on the net, sometimes a driver for similar models of this brand may come up.

The phone may not be detected by the computer due to viruses

Trite, but all sorts of virus programs can block work with external mobile devices. Try checking your computer with Dr. Web CureIt!, in some cases it can help.

If the problem of detecting a mobile device by a computer is not resolved, reset the settings

If until now, your computer does not see the phone via USB, resetting the smartphone using Hard reset. Go to the settings of your phone, select the "Backup" menu item, and select "Data reset" in it.

But I immediately warn you that you will lose your files and settings located in the internal memory of the phone (files located on the SD card will remain intact), so this item should be used only as a last resort!

Conclusion

As you can see, problems with the lack of visibility of the connected phone on the PC can be both software and hardware in nature, and there are a considerable number of such problematic factors. I would advise you to first pay attention to the likely mechanical damage in the cable and device, and only then switch to software methods.

In many cases, a simple reboot of the smartphone (temporary removal of the battery) can help, as well as working with the phone's USB connection settings. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.

P.S. For lovers of visual demonstrations, I present a video on the subject:

Sometimes it is necessary to connect Android to a computer under Windows control to transfer certain files. Sometimes problems arise, and the computer does not see the phone via USB, it charges, but does not allow you to move files.

We propose to consider the possible options in a generalized way, and then discuss all the solutions to the problems.

Reasons why the computer does not see the phone via USB

This may be due to software incompatibility or technical problems. From time to time, the cable is damaged, the contacts in the smartphone break. In the first case, you need to try another cord, and in the second, contact a service center to replace the connector. Also, a broken port in the computer can cause problems, so switch the wire to a different socket to fix the problem. These are the most common hardware failures.

It is more difficult with software errors, since there are a lot of reasons for failures. These may be missing or outdated drivers, incorrect connection modes (when the computer charges the smart, but blocks the transposition of documentation into folders) and other incompatibilities, which we will discuss in detail below.

What to do if the computer does not see the phone?

Listed below are all the ways that can help solve the cable connection problem.

Check your USB connection settings

The method will help if charging is in progress during pairing, but the information cannot be reset. To transfer documents, you need to connect your Android as a media device (MTP). To do this, follow these steps.

Attention!In some cases, you may have to connect your phone to your computer and switch between different options several times before the desktop recognizes your device as a media device.

If you have older versions of Android, then try this.

Connect the device to the computer, it should be recognized.

Install the USB MTP driver

It happens that the smartphone is not displayed due to driver problems, so try updating it.

Once the driver is installed, the PC should recognize the Android phone. You may need to restart your computer for the update to take effect.

Download and install Media Feature Pack for Windows 10

We have already mentioned that the MTP protocol must be used to transfer content. It is associated with Windows Media Player, and some versions of Windows 10 do not have Windows Media Player and support for related technologies. If your Windows version 10 does not recognize Android, please download and install Media Feature Pack from Microsoft official website.

Use the included USB cable

Remove Android Drivers

Sometimes the system does not have the latest drivers or they are not installed correctly. It is recommended to remove them and reinstall them.

It remains to check if the method worked.

Activate USB Debugging

From time to time, the connected gadget is recognized when USB debugging is active. If you are using Android 4.2 or later, this feature may be hidden. To enable it, follow the steps below.

1. Go to "Settings - About phone".
2. Click on "Build number" 7 times.
3. Go back.
4. Open "Settings - For Developers".
5. There, scroll down and activate "USB Debugging".

Sometimes it is already on, in which case it should be turned off.

Turn on Airplane Mode

If Windows no longer sees the phone, start the flight mode through the quick settings panel in the blind or by going to the "Settings - More" path. Often after that the device is recognized by the PC. This is an easy way, so feel free to try it out.

Reboot your phone in Recovery or Fastboot mode

Read about how to enter it in our other article, where we described the process for each manufacturer. After you get into Fastboot mode or recovery, connect your smartphone to the PC, wait until the necessary components are installed. After that, an explorer should open in front of you with a proposal on what to do with the connected device. When finished, restart Android.

Install KIES from Samsung

If your Samsung gadget is not recognized by Windows, download software KIES from the manufacturer's official website and install it on your computer. With it, you can definitely connect your smartphone.

Use USB 2.0 ports

Try switching the cable from USB 3.0 to USB 2.0. Users reported that it sometimes worked for them.

Reinstall ADB

Windows occasionally does not recognize the smartphone due to problems with the Android Composite ADB interface, so you should reinstall it.

This solution works with Android 5.0 and newer OCs, but it may also be compatible with older Android versions. Users have reported that it is not always worth downloading the USB driver from Google, and often this problem is resolved simply by following the first four steps.

Reboot your Android device

Sometimes this simple solution is the most effective. People have repeatedly reported that after rebooting the phone, the computer recognized the mobile phone without problems.

Connect your phone directly to your computer

Some USB devices may not be recognized if you connect them to a USB hub or extension cable. Therefore, if you are using a USB hub, disable it and connect your Android directly to the PC to solve the problem.

Clear cache and data for external system storage and storage systems

This solution works on Android 6 and up. But if you have an older system, try doing this anyway.

After deleting the cache and data, restart the gadget and reconnect it to the computer.

Sync Android to PC with a third party app

This does not guarantee 100% performance, but it often helps. Just install the sync app from Play market, which will help the computer to recognize. Try, for example, Mobile Go to connect and transfer data from Android and iOS to PC.

There are many reasons why the computer does not see the Android phone. We hope that these solutions will be useful for you and you will solve your problems.

In the modern world, a smartphone is an indispensable thing, so when your favorite gadget takes a long time to charge or does not turn on at all, it becomes a whole problem, especially if it is a new phone.

First of all, we think about how to charge our gadget, especially when we are in a hurry and look for the causes of problems in the phone, but before that, you should also carefully examine the related equipment:

• Socket - if the wiring is old or there are some other problems with electricity, then this may well explain why the gadget either charges or not;
• Charger - check its integrity, it may be damaged;
• Incompatibility of the charger with the gadget - if the inputs are similar, this does not mean that the charger is suitable for both smartphone models.

If you are convinced that you do not have any of the above problems, you can proceed to the study of the phone itself. We will look at the most common reasons why the phone does not accept a charge.

The gadget is charged only from the computer

When the phone is charged only from the computer, but the smartphone is turned on and works normally, it is worth checking the charger. But if the charging is in order, and the smartphone does not see it or writes that charging is in progress, but in fact it is not, there is a malfunction in the phone.

In some cases, flashing the gadget or replacing the input helps, but only a professional can do this after they examine the device and fix the problem.

What to do if the phone does not charge, but the charger is connected

It happens that the phone shows charging, but does not charge, and even after several hours of recharging, the battery remains at zero. Or, if you do not charge the phone for a long time, the battery does not accept a charge. In both cases, there may be several reasons:

• Charging does not charge;
• The phone's battery is defective;
• Many applications and other services are open.

If the case is in the charger, the gadget detects the charger, but due to technical malfunctions it does not charge. This situation is probably known to the owners of the iphone, since the cable malfunctions from frequent use. Try replacing the wire, maybe that's the issue.

In the case when the problem lies in the battery, you will have to buy a new one or even turn to the master, see in such smartphone models as samsung galaxy S6, LG Optimus Vu, HTC One X have a built-in battery, which means that you cannot replace it yourself.

The latter option is very rare, but still has a place to be, especially if you are the owner of a DNS or Fly smartphone. In this case, you just need to close all programs, in particular Wi-Fi, the Internet and your favorite games, and then leave your android alone while it is charging. If the indicator shows that the charge is on, you can congratulate yourself, you just fixed the problem.

Bad contact contact

You are familiar with the situation when the phone is working and charging is in order, but for some reason the smartphone does not respond to the device when connected to the network. You don’t know what to do anymore, because the phone doesn’t charge for a very long time, but the reason for this can be banal.

From time to time, dust gets into a cell with a removable battery, especially for older Samsung models. If you do not clean the inner surface, dirt accumulates, creating a layer that prevents the contacts from mating normally, which is why the phone does not charge. Try removing the battery, then clean it and the inside of the case with a Q-tip. Also pay attention to the "teeth", if they are slightly bent, correct this using a match, but proceed carefully so as not to damage the contacts.

The phone does not charge from the charger

When the phone does not charge from charging, the cause should be sought in the charger or in the gadget's connector. In this case, it’s very easy to find out what really doesn’t work, just connect the mobile phone to a PC or use the “frog” universal charger, but it will be problematic to use it every day, because you have to turn off the phone every time and pull out the battery. Another way to charge the phone from an external battery, but this is also not an everyday option.

Smartphone charging backwards

Not everyone knows why the charging goes in the opposite direction, and at the same time the phone does not take a charge, but, as it were, gives it away. Faced with such a situation, many are simply perplexed. The reason for this unusual phenomenon is simple - a failure in battery calibration, this happens from time to time with Lenovo phones, but do not panic, because the problem can be solved very quickly.

To eliminate the anomaly, first you need to discharge the battery to such an extent that the smartphone turns itself off. After that, remove the battery for a couple of minutes and put it back in the phone. Connect the gadget to the charger, but do not turn it on until the charge is on.

Phone takes a long time to charge

If your smartphone has been on charge all night, but is not fully charged or the indicators are not more than 1 percent, then the problem lies in the battery. Of course, for the first time, you can even charge the phone up to 100 percent, but not only will the process take a long time, but the gadget will be discharged in just a couple of hours, if not earlier.

In this case, you have only one way out - to buy a new battery and then safely use your irreplaceable gadget.

You can figure out the problem yourself, but if you didn’t manage to find out why the phone is not charging and you have tried almost all of the above methods, it is best to take the smartphone to the master, because only a specialist can establish the true cause of the malfunction.

Many who own Apple technology will agree that sometimes it can be very capricious and forces you to buy only original devices for it. But all this is not connected with the fact that to shake out the money from you to the maximum (although there is some truth in this too), but to ensure the long service life of the device. Today I will analyze such a problem: the iPhone is not charging in the car from usb. And also, I will tell you how to solve it and why it occurs at all.

iPhone does not charge in the car from the radio or cigarette lighter - solution

As I wrote above, Apple technology is capricious for a reason. If your Android phone is quietly charging from the cigarette lighter, and the iPhone flatly refuses, then there may be several reasons:

1. Unstable voltage
2. Non-original device (cable, or device that is installed in the cigarette lighter)
3. radio tape recorder
4. USB connector

And now in order to each problem. In the first two cases, the device is most often to blame, which is not able to maintain a normal current for charging. Usually these are "No name" manufacturers, so buying a branded cigarette lighter socket should solve the problem with iPhone charging. Many car owners speak well of the Belkin charger. In rare cases, the problem may lie in the wiring of the machine itself, and here it is already necessary to contact specialists. An ordinary multimeter, which costs from 200 rubles, will help you to recognize this problem. You measure the voltage in the cigarette lighter itself, after which it will be clear - the problem is in the wiring or cigarette lighter of the car or in the device. which you bought.

The next problem why the iPhone does not charge in the car from usb may lie in the radio. You can find out its presence using the same multimeter. After measuring the voltage, everything will fall into place. For normal operation of the device, 1 Ampere is needed, if the measuring device gives out more, there is nothing to worry about. It’s another matter if you get less than 1 ampere, since such a voltage can not only simply not charge your iPhone, but also damage the battery or even render it unusable.

And the last reason why the iPhone does not charge in the car from usb is the USB connector itself. Namely, if you have USB 2.0, then the iPad, for example, will charge, but the iPhone will not. The solution to this problem is very simple - buy a device with a USB 3.0 port. It is worth saying - any consultant will assure you that all devices are currently compatible with USB 2.0, but this applies to data transfer. That is, USB 2.0 has a much lower speed than USB 3.0, but the current strength of USB 2.0 is 500 mA, while USB 3.0 has 950 mA, which is why the problem of charging an iPhone occurs when using an older generation USB port .

Precautions for Using Apple Phones

In conclusion, I will say: in order for your iPhone to last for a long time, it is advisable to use original chargers, usb cables. If you use memory devices from other manufacturers, try not to take Chinese counterparts and always look at specifications. This will save you from re-purchase, as well as your phone from handing over to the workshop. Using cheap analogues, you spoil the battery, and there is always a risk of simply “burning” the board on your iPhone.

If you encounter a situation where your iPhone has stopped charging, don't panic. This does not mean that your device is broken and you need to go for a new one. The reason may not be serious. And in this case, you can easily cope with the problem yourself. You don’t have to go to the master and lay out a round sum for repairs.

Sometimes it happens that the iPhone does not charge from the computer. But it happens that you can’t charge your iPhone from the network. Today we will talk in detail about the first situation.

What are the manifestations of this problem? When the gadget is connected to the PC, the battery indicator usually pops up and a characteristic sound is heard, indicating the connection. If the charge does not go, nothing of the kind is observed.

Note that the owners of devices of the fourth line face such troubles more often than others. The easiest solution to this problem is to restart your smartphone. But it helps if there were problems of a system property. In other cases, the approaches will be completely different. Read about all this in detail below.

Charging problems can occur with the owner of absolutely any iPhone model. No user is immune from this. The most common sources of such trouble are listed below:

1 The device is connected to an old PC or laptop. If charging from USB does not work, the problem may be in the port. For some PC models, it is common to disable these items to save power. Many users do not know about this. Therefore, try to either turn on the ports, or find an outlet and use it. 2 The cord is damaged or defective. Often, charging does not work, because the user bought a Chinese fake. For goods from the Middle Kingdom, this is a common practice. In this case, you will have to fork out for the original cord. The same can be recommended for damage to the "native" accessory. In general, iPhone cables are very fragile, so they should be handled with care. 3 The lower loop is defective. Sometimes an "apple" device declares to its owner that the accessory is not supported by it. The problem, of course, is more serious than the previous ones. But there is no need to panic here either. It is better to go to the repair shop as soon as possible and have the cable replaced. In terms of time, this operation does not last long. 4 The device is damaged. After being dropped and bumped, iPhones often stop charging. Here, too, you should not think for a long time and find out the reasons yourself. And even more so - to delve into the "stuffing". Just run to run to the service. Perhaps the specialists will be able to restore your device.

What to do if iPhone won't charge

If your gadget has stopped receiving power from the original element, do the following:

1 Restart the system. This method seems so simple that users don't even think about it when they encounter difficulties. This simple action can solve more than one problem with the iPhone. 2 Carefully inspect the cord, charger, port, socket. Let's say checking the charging unit is very simple. The cord is disconnected from it and an attempt is made to work with USB. If everything is fine, the source of the problem is hidden in the block, because the cord is definitely working. 3 Clean the charger connector. Any more or less experienced owner of an Apple smartphone probably knows how to do this. 4 Apply Recovery Mode. In terms of efficiency, it is close to a normal reboot, but better at eliminating technical problems. including those arising from charging. But do not forget that after restoring in emergency mode, the device settings will return to the original ones. Therefore, take care of the backup in advance. 5 Go to the repair shop if none of the above methods has led to a positive result. This means that your device needs a thorough inspection and serious intervention. Surely you will need to open the case and carefully examine its contents. Probably. repairs won't be cheap. But your gadget will be saved. In terms of time, replacing a battery or a connector for a charger will not take more than 30 minutes.

The introduction of the device into the named mode is carried out as follows:

• The user turns on the iPhone.
• Clamps the Home element.
• Connects the device to a PC or laptop using a USB cable.

The fact that the gadget is in the desired mode will be indicated by the corresponding picture on the display. Getting out of it is even easier - you just need to click on "Power".

iPhone Battery Charging Rules

And in order for the battery of your device to last as long as possible, do not neglect the following rules:

1 Do not use or recharge the device in critical temperatures. The developers consider the range of 16-22 degrees (but not more than 35) to be the most acceptable. Overheating of the case is very dangerous and leads to an irreversible decrease in battery capacity. 2 Use only "native" charging to work with the gadget. Or take at least a certified cord. If you do not ignore this recommendation, you will never run into problems. that have been discussed in this article. 3 Do not allow the absolute discharge of the iPhone. I mean up to 0%. The life span of a lithium-ion cell is expressed in terms of the number of full discharge cycles. The latter term refers to the situation when the device has used up the entire capacity of the battery. High-quality batteries can withstand up to 600 cycles. And according to the manufacturer, the resource of iPhones is 500 cycles, and other "apple" gadgets - up to 1000. Each time you connect the device to a power outlet or to a PC, the battery life decreases. And the “guilty” of this is just the depth of discharge. It turns out that the more a lithium-ion cell is discharged, the faster it will die. Accordingly, to increase its resource, do not allow full discharge.

However, the personal experience of many users suggests that, of course, no one can follow these rules exactly. You won’t walk around with a thermometer and take it out with your iPhone. It is enough just to avoid hitting the device with the hot rays of the sun, do not leave it in the car and do not charge it with something pressed down.

In addition, it is known that with an increase in the charge voltage of a lithium-ion cell by only 3-5%, it will lose capacity with each cycle 100% faster. To prevent this, the manufacturer has built in special-purpose controllers that monitor the process conditions in the original unit and in the device itself. In Chinese fakes, of course, there is no such technology.

Conclusion
