Purchase expensive smartphone these days (due to the depreciation of the dollar) is an even more expensive and responsible matter than a year ago. Therefore, it is doubly offensive if a newly purchased phone somehow malfunctions.

I'll tell you my story related to the Samsung galaxy s3. About six months after the purchase, I began to notice that the phone was discharged very quickly - a 100% charge was enough for literally 2 hours.

And I don’t even play on my phone! Sometimes I could not touch it, but it would still discharge in an instant! And then one fine day I just charged the phone, put it next to me, and then after a couple of minutes it beeped - 15% charge! how so? I connect it to the charger, but it doesn't charge! Horrors immediately replay in my head: being repaired, a week or more without a phone.

Okay, it occurred to me to take off the case and look at the battery. And the battery is swollen! Just to huge sizes! How has it not exploded in my hands yet? Very lucky! As a result, of course, I didn’t put the battery back, I bought a new one the next morning, and now the phone charges normally. By the way, the battery could have swelled because I left the phone on charge all night. I don't do that anymore.

But a swollen battery is only one of the reasons why the Samsung galaxy s3 does not charge. What other reasons could there be?

2. Faulty charger. We have three identical Samsungs at home and three chargers, respectively. So we noticed that not all charging device They charge the same way - some faster, some slower. It is important that the charger is original - non-original chargers do not charge Samsung well. And in general, we have one that not only does not charge, but also discharges the Samsung!

3. There may be problems with the cord. It's easy to check - try charging another phone using a charger (the same applies to a removable charging unit). If the charger is faulty, you will need to buy a new one.

4. Problems with the charger inlet in the phone itself. It’s also easy to check: take another charger. If several different chargers do not charge your Samsung galaxy s3, then it’s time for repairs.

As you can see, not everything is so bad in cases where the Samsung galaxy s3 does not charge - most often you can buy additional accessories like a battery or charger, for which, by the way, the warranty upon purchase lasts quite a bit - about a month, it seems.

Unfortunately, today people who own Samsung phones suffer from the fact that the phone does not charge or charges, but with great interference. This problem is Lately has become quite common.

This article is for those people who also encountered this problem. If this problem is discovered, you must immediately take the necessary measures, because this problem cannot be left to chance. Later in the article we will look in detail at why this happens to the phone (it won’t charge) and what to do in such cases.

Cause

If you are trying to charge your phone from a computer device or using the standard method through an outlet and your Samsung phone does not work, then the reason for this may be a faulty cable. First of all, you need to carefully look at all the cords on your phone. If you checked and they turned out to be intact and working, then the reason is not in them. It is necessary to further search for the cause.

The reason may be:

• It is quite likely that the connector itself is not fixed in the phone. If this is indeed the case, then it will need to be replaced;
• In the event that the same connector is slightly torn out of the so-called printed circuit board, the phone will also not charge;
• The power controller may be broken. If this is indeed the case, then it is necessary to replace it;
• If the phone is , then this indicates damage to the power circuit. This part is quite significant in the entire system, so it is necessary to carry out diagnostics before directly repairing it;
• A fairly small percentage may account for other problems.

It is also quite likely that the problem is that the phone discharges quickly, but very slowly or does not charge at all. Then the problem is in the battery itself.

Such problems are quite common and people do not know what to do in these cases. Therefore, we provide solutions to problems.

Troubleshooting

First of all, it should be noted that if the problem is not with the charger, then it is best to contact a specific service center. They will quickly carry out the necessary diagnostics and determine the cause that you were unable to determine.

In many centers, all parts are available in order to replace the breakdown and provide repairs to the High Quality. Often, in all centers the price for phone repair is acceptable. Moreover, the advantage of service centers is that they provide a guarantee for the entire phone.

A fairly common reason for a phone not charging is a breakdown of certain electronic components in the phone. In the event of such a breakdown, any service center must explain to the person the reasons for this malfunction and what to do to prevent this from happening again. It is also worth understanding that when they say that the phone is not charging, they also mean that the phone’s battery is quickly draining.

A fairly common and common reason is the battery breaking down due to long-term use. In such cases, you can simply replace the battery with a new one, and it will last for a long period.

Very often the phone turns off due to low battery when a sound or vibration signal is sent. This is justified by the fact that the phone once fell and such a breakdown occurred.

Not so often, but the phone is discharged due to internal problems, namely, some kind of virus. This reason only happens on smartphones. To prevent such a problem, you must remember that antivirus can be used not only on computers, but also on mobile devices.

There are also failures inside the phone, after which the phone itself cannot recognize the charger. In this case, recognizing the problem, much less eliminating it, is unrealistic. Here you just need advice and help from specialists.

The minimum problem is that there is a glitch in the screen. For example, after flashing the phone, the screen may not display the fact that charging is taking place, but the battery itself safely receives the charge it needs.

If your battery isn't charging as well as it should, don't immediately assume that your charger is bad or your battery is bad. Based on personal experience, the problem in this case (and the solution) may be much simpler than you think. If your phone or tablet isn't charging properly or isn't charging at all, we'll show you 10 ways to fix a phone that's having charging problems.

Why is my phone not charging?

This problem can occur for various reasons. Either your phone doesn't charge at all when it's connected to the charger, or it charges very slowly (sometimes a little faster than the discharge process occurs). In principle, this is a very common drawback, and we ourselves have encountered this. Below we provide a list of possible solutions.

Repair the USB port yourself

The fastest, easiest and most successful solution would be a little soldering on your working device. The problem is that often the metal surfaces inside the USB port and microUSB charger do not allow good contact either due to a manufacturing defect or due to the charging cable being constantly connected and disconnected.

All you need to do is turn off your device, remove the battery (if possible) and use a small object, such as a toothpick, to lift up the small plate inside the USB port of your smartphone or tablet. Do this very carefully and gently. After this, you need to reinsert the battery and connect your device to the charger. In 9 out of 10 cases this method gives a positive result.

Remove lint, dust and leftover sweets

Do you carry your phone in your jeans pocket? If so, then in this case the culprit will be various piles: we have already lost count of the numerous cases where the cause is bad USB charging it turned out to be lint from your Levis.

We've also seen phones whose charging ports were clogged with chocolate: similar cases The phone was placed in the bag next to the package of sweets. A can of compressed air will help blow out the foreign elements and your USB connection will be back to normal.

Replace cable

The most unreliable element of the charger is its cable, and not the adapter that plugs into the outlet. In this situation, users are especially vulnerable Apple products, since the normal service life of expensive branded Lightning cables is likely to be no more than 15 minutes. Many cables are used very harshly, and endless bending and twisting takes its toll.

Replacing the USB cable that came with your phone with any other is another aspect of a negative charging experience. The most in a simple way To determine a faulty cable, you will need to replace it with another one, followed by checking how it works with your device. If everything is in order with such a cable, then it is time to purchase a new cable, and if not, then something else will be the culprit of the problem.

Diagnosing a suspicious adapter

If the cable doesn't look like it might be causing the problem, then it's worth checking the adapter that plugs into the outlet (especially one that has a charging cable that can come loose). We've encountered problems with numerous chargers where the USB port becomes a little loose due to frequent unplugging and plugging.

We also recommend that you make sure that the same adapter-cable combination works on different devices - this can help you rule out the possibility that the fault lies with your device and not with the cable or adapter. In addition, it would not hurt you to check the functionality of the outlet, that is, whether there is any malfunction in it.

Safety first

Our advice to you: do not charge your phone near water or in extremely hot or humid conditions. Also, you should not overcharge your device; charging your phone overnight when it only needs two to three hours is not a good idea. This may cause the battery to explode or damage your phone.

Even though your device has a built-in charge controller for your battery, sometimes it doesn't work (you may remember stories of exploding batteries from 2013). Better to be safe than sorry. Or burn to the ground.

If you're replacing a charger or cable, be careful: the internet is littered with reports of cheap third-party chargers exploding in the middle of the night or overheating smartphones. As with any electrical equipment, make sure whatever you buy meets certain safety standards.

Replace the battery

Unfortunately, batteries do not last forever, and after a few years they find it difficult to keep a full charge. The more often you charge and discharge them, the sooner they will have to be replaced. If your battery starts to die after just 6 months, then it is probably simply faulty and you should file a warranty claim for a free exchange. new battery. But if it is already 2-3 years old, then in this case the “life” of such a battery is coming to an end.

Note that some faulty batteries are very easy to identify, as they begin to swell or leak electrolyte. If nothing like this is visible from the outside, then you need to remove the back cover of the device and inspect the battery (if, of course, you succeed - some devices are produced with sealed battery compartments).

If the back cover of the device does not open, we recommend that you place the device with the screen facing up and rotate it around its axis. A swollen battery will deform the back cover - you may not see the swelling on the battery, but it will be enough for the device to spin. If you suspect that your battery is swollen or leaking, remove it or take your phone to a service center and buy a good replacement battery.

Different chargers charge differently

As a rule, charging from an electrical outlet is always faster than from a computer or laptop, since computer USB ports designed for low current. The socket can supply twice as much current as USB port, and in the case of so-called fast chargers – even 5 times more. This indicates that charging is much faster. If your phone is charging slowly, and from a laptop, this is the essence of the problem.

If your charger doesn't work very well in your opinion, try something else that suits your device. A charger from another phone will not always be able to provide the required voltage and current - for example, a charger for a Bluetooth device will be less powerful than one that is specifically designed for charging smartphones. In the case of new premium phones, it must be a phone that supports the feature fast charging, although this phone's charger is not a fast charger. We advise you to read the information on this topic printed in small print in the documents for such phones.

Upgrade or rollback

Software updates and new ones Android versions may cause some damage to the life of your battery, especially when updating an older device to the current software. New devices are often optimized to take advantage of the latest software, having pre-optimized hardware and software on board while your 2-year-old device experiences certain problems when you receive an update.

If this happens to you and you cannot get rid of such problem, then you should downgrade your device to an earlier version of Android. But remember that this comes with big risks. Highly recommended to protect your device latest versions Software, although it's worth noting that the risks associated with leaving an old working version on your device are often negligible.

Likewise, sometimes your device's battery life can be significantly increased thanks to a certain update, so if you think you're behind the times with your old Android software, you should go to Settings and open About Device " to check for updates.

Turn off your mobile device

When various applications or functions intensively use the battery while it is charging, this will affect how long the battery life will decrease. If you are charging a device and at the same time communicating with someone on Skype at 100 percent display brightness, it is natural that such a device will require a longer period of time to charge than with the screen off and Wi-Fi and 4G turned off.

If you want your battery to charge as quickly as possible, switch (or turn off, respectively) Airplane mode. Imagine that your device is immersed in a kind of energetic sleep. Or fueled by a Red Bull energy drink in the dark.

Calibrate your battery

Sometimes what your device “thinks” about your battery may be different from what actually happens. The effect in this case is that your phone may perform differently based on an estimate of the remaining charge in the battery, including limiting performance before the charge level drops to as little as 2 percent.

Not long ago we already published detailed guide on the topic of how to calibrate a battery, so we will not re-post the information, we will only say that this is a very useful option that is worth trying before saying goodbye to your “dead” battery forever.

If all else fails, then you need to double check that you actually have the power saving mode turned on. This is the first thing the device manufacturer's office will ask you if you call them for assistance. By the way, this may be the next step for you if none of the methods described above helped you.

Samsung phone won't charge

When faced with the problem of recharging your smartphone, a number of problems can be solved yourself. After conducting an inspection and a little diagnostics, you can easily rule out or eliminate the most obvious and common reasons why your Samsung phone Samsung Galaxy, A3, S6, S4, S3 and other models stopped charging.

The most common reasons when a Samsung smartphone does not charge

• deep discharge;
• cord and power supply;
• connectors;
• accumulator battery;
• software problems;
• mechanical damage;
• moisture ingress.

Let's look in more detail at each possible area that could cause such a defect to appear.

Deep battery discharge

If you do not follow the manufacturer's recommended discharge and recharge mode, then you will not receive power from the electrical network, the gadget could get a deep battery discharge. This happens when the voltage drops to the required nominal value, which is indicated directly on the battery itself in Volts.

And now, when connected to a PC or charging, devices cannot recognize your smartphone. At home, it will help to leave the gadget for a long time (several hours) connected to the charger. Or use a frog attachment.

In most cases, this helps restore the battery capacity, or a Samsung phone repair shop will help you, where they will use a laboratory power supply with the required power for this.

Charger

Check charging on another device, connect the cord to the PC. It is necessary to eliminate the problem of recharging in the cord and power supply.

Inspect the cord and power supply carefully. Visually they should not have any damage. The cord must be smooth, without bends, kinks, or fractures. The insulation must be along the entire length.

If you find any damage, be sure to replace the cord or unit with a new one. The use of such components is fraught with short circuits and failure of more serious and expensive phone components.

Connector problem

The next step is to inspect the charger connector. Obvious mechanical damage will immediately indicate the need for replacement.

The problem may also be poor conductivity due to contamination (dust, corrosion from moisture). Convenient to use a toothbrush. Gently clean the connector and try connecting the charger again.

Accumulator battery

It is likely that the Samsung Galaxy, A3, S6, S4, S3 and other models are not charging due to the failure of the battery itself. Battery swelling or oxidation directly indicates this. Then you need to replace it with a new one. You can do this yourself, or you can contact the service center specialists.

Software failure

Some malicious applications can cause such damage to your gadget. Regular anti-virus cleaning of the program is necessary to prevent any malfunctions in the operation of the smartphone. If you can no longer turn on the gadget because it is dead, contact a specialist for restoration work. They will reset the settings to factory settings or offer flashing.

More serious reasons why samsung smartphone stopped taking charge, they will determine it at the service center and it is best to correct the defect there. This way you will receive a guarantee for the work performed and free service if the problem recurs.

The reason for writing this article was the inadequate operation of the phone Samsung Galaxy S3, who served faithfully for a year and a half. However, before I started writing the article, I analyzed and tried on my own phone a sufficient number of tips and recommendations designed to eliminate the glitches that arise specifically in this model.

1. Some reasons for glitches in the phone.

1 . Telephone makes frequent sounds and at the same time, the “on” mode icon appears in the upper left corner of the display Automobile"although this mode is disabled.

2 . At When connected to a computer, the phone is not detected, but at the same time the notification “ Stand connected" and, accompanied by sound, an icon and a notification about the enabled mode pops up. Automobile" If the phone is not disconnected from the computer, then after a few seconds a notification appears that the application TouchWiz screen completes its work. Then this application starts its work again and after a short period of time finishes it again and then restores it again. This process may last until the phone is disconnected from the computer.

3 . If you try turn off the phone from the button the moment he makes frequent sounds and the on-mode icon “ may appear on the display Automobile", then after turning off the phone immediately turns on itself. Moreover, after turning off, it will turn on on its own until you remove the battery for a while. At this moment I want to smash my phone against the wall.

4 . At connecting to the charger an alert appears on the display: Stand connected" The indicator shows charging, but the phone does not charge, or charges very slowly. Also, during charging, the “Car” mode icon may pop up accompanied by sound.

5 . The phone can be reboot spontaneously.

To eliminate the above problems, we tried some tips and recommendations that were found on the Internet:

reset to factory settings, flashing the phone (I don’t recommend doing this), reinstalling the usb driver, replacing the usb cord, buying an original usb cord, removing the battery for one hour, removing the SIM card, reinstalling the PC Sync program on the computer, installing Samsung Smart Switch" - all these dances with a tambourine did not help.

3. Causes of malfunctions.

It was experimentally established that the reason for this is usb phone connector and first of all this dirt inside the connector, gets there along with the plug of the charger and is gradually compacted by this plug, causing the cord plug to no longer fit into the connector completely.

The second reason is oxidation of contacts inside the connector, which occurs under the influence of supply voltage, moisture and dirt, and contributes to the formation of transition resistances between the contacts, which is why glitches occur in the phone, because it determines these resistances somehow in its own way.

The third reason is unbending the outer walls of the phone's USB connector, due to which the plug begins to dangle in the connector and as a result, contact between the tracks of the plug and connector is lost. As a rule, such a malfunction occurs when we continue to use it while charging the phone, gradually expanding the walls of the connector.

In all these cases, the USB connector must be replaced, but you can try preventive maintenance and restore normal operation of the phone.

4. Preventive repair of the USB connector.

If the phone makes only sounds and notifies about on mode « Automobile", just clean the connector from dirt. To do this, we need alcohol and sticks - toothpicks, which are selected in thickness so that the tip of the toothpick can move freely inside the connector between the outer wall and the central pad with the contacts.

The stick can be sharpened with a knife, but this makes it softer. In principle, you can work with a soft tip, but in this case you will need more sticks.

Turn off the phone and remove the battery.
Use the tip of a stick to carefully remove dirt from the connector. Then moisten the tip generously with alcohol and wash away any remaining dirt from the inside. If the tip becomes completely dirty, then change the stick. In my case, it took three sticks.

We carefully move the tip of the stick along and across the contacts and monitor the condition of the tip. When it becomes dirty or completely soft, take another stick and clean the contact paths until the tip remains clean.

Now we dry the connector, insert the battery, turn on the phone and listen to its operation for a couple of days. If the sounds disappear, then the job is done. Congratulations.

If your phone has problems with connection to a computer, then first of all we clean the connector from dirt and try to connect. If nothing has changed and the phone continues to glitch and the computer still does not see it, you will have to align the outer wall of the USB connector to return it to its original state.

Turn off the phone, remove the battery, SIM card, flash drive, if installed, unscrew 10 screws and remove the back cover. Just grab the lid with your fingers by the thin side of the body and pull it up, and it will give in easily.

We take a screwdriver with a flat tip, place it on the USB connector, as shown in the figure, and give the handle one light blow with a small object, for example, pliers. Then insert the battery, turn on the phone and connect it to the computer. If the phone is buggy and not detected, how multimedia device, then turn it off again, remove the battery and give another blow to the connector. In my case, two hits were enough.

The blows must be applied carefully so as not to damage the board or break off the pins of the connector with which it is soldered. Otherwise, you will have to take the phone to a workshop and have the connector resoldered.

These are, in principle, all the points that I had to face when using the phone Samsung Galaxy S3. I agree that this is not all. But if your phone shows one of the above symptoms, then before contacting a specialist, you can try to fix the problem yourself, and if necessary, carry out prophylactic usb repair connector. Well, if it turns out that you still have to change the connector, then your soul will be calm, since everything was done on your part. And as a supplement to the article, watch the video.

Alternatively, read an article that describes one of them. Perhaps it will suit you better.
Good luck!

So-called wireless chargers for mobile devices have not been a sensational shortage in domestic retail for quite some time. However, many manufacturers have not yet released their own wireless charging systems for their smartphones, and the popular Samsung Galaxy S3 is among such devices.

In fact, just last year, just before the release of the new flagship in the line of smartphones, Samsung representatives several times mentioned the company's plans to release... But these promises remained promises, and users have not yet seen Samsung’s official version for the S3.

And it’s very likely that they won’t see it. The Internet is filled with rumors and speculation about the future, and long-awaited Samsung Most likely it will start releasing for the new flagship. Wait and see. However, if you already have an S3 and want to get just such a charger, without waiting for the manufacturer to please you with something more or less acceptable, both in functionality and price, then there are also options.

Craftsmen, it turns out, have long come up with a fairly simple method. So, in order to add the option to your Galaxy S3, it will take a little time, a little money and accuracy. The proposed solution is based on a relatively inexpensive set for wireless charging no longer the new Palm Pixi communicator.

Further point by point:

1. We collect the necessary parts and tools:

– Palm Touchstone charging dock (about $10 – prices hereinafter)
– Palm Pixi Touchstone back cover – back cover of the Palm Pixi smartphone ($3)
– network adapter and USB cable ($5) – this is important, similar devices from other manufacturers are not suitable
– copper tape with adhesive backing
- scotch

2. Disassemble the back cover of the Palm Pixi
It is necessary to carefully peel off the black gasket on the back of the cover. You can do this simply with your fingers. Next, remove the silver sticker. Both parts - the gasket and the sticker - must be saved; they will be needed later.

After this, before tearing off anything else, you need to take a small piece of paper (kitchen parchment works great), cover the visible part of the circuit with it and carefully but carefully mark the contours of the coil and the four metal disks surrounding it. We put the resulting one aside - it will also come in handy.

Now, using a knife, carefully separate the copper coil from the lid (in fact, these parts are the elements of wireless charging) and four metal disks.

3. Install wireless storage components on the Galaxy S3
Remove the back cover of your S3. We place the parts removed from the Palm on the cover of S3: we place the coil and the L-shaped board in the place and as shown in the picture.

Then we cover the top of the coil with a silver sticker. Now, guided by our drawing, we place all four metal disks around the coil, and then fix their position with tape. The disks must be secured securely, since they are the ones that are held on the base of the charger.

4. Connection
In order for the now upgraded back cover of the Galaxy S3 to transfer charge, you need to create the connection diagram correctly. To do this, prepare four pieces of copper tape measuring 5x25 mm each.

On the L-shaped part of the board we find two terminals. We take one of the prepared copper ribbons, bend it approximately 5 mm from one edge and cover the upper terminal with the folded end, then stretch the rest of the ribbon to the edge of the cover at a slight angle and glue it tightly to the plastic (see picture). We make a bridge from the second terminal to the edge of the cover in the same way, but at a slightly larger angle. Be sure to make sure that the copper tape fits well to both terminals. You can press the tape more tightly to the terminal using a regular pencil.

To the left of the battery on the smartphone body we find a couple more terminals. We roll the two remaining copper strips from the ends in the same way as the previous ones, and carefully but securely glue them to the terminals and the body as shown in the picture above.

5. System check
We install the cover on the Galaxy S3 and place the device on the base connected to the mains. The indicator on the smartphone screen should show that the device is in charging mode. Works? Congratulations!

Now you can turn everything off, remove the cover again and cover all the equipment installed there with the black cover removed from the Palm (or black electrical tape) so that everything is really beautiful.

If after all the manipulations the smartphone does not want to charge, then there may be several reasons for this:

• the ends of the copper tapes are poorly glued to the terminals (check, press again with a pencil or glue);
• a piece of tape on the cover touches the opposite tape on the housing terminal (we check that the ribbons on the cover are narrow enough and do not immediately contact both tapes on the housing);
• the components on the cover are installed incorrectly (we check the existing template, install the coil correctly, and then check the voltage at the terminals with a multimeter - it should be 5.5-5.6 volts).

This is all. By the way, your Samsung Galaxy s3 will charge much faster through the Touchstone base than from USB.

Is your phone broken? ? The situation is not pleasant, but still this problem can be solved. In our pcmol service center, the first thing they will do is diagnose it in order to determine the cause of the breakdown, because there may be several reasons.

1. The power connector is damaged. If it is broken, then it will need to be completely replaced. This will take about 2 hours.
2. If the power chip is faulty, it will take at least 4 hours to replace it.
3. Liquid got into the device or the phone was damaged as a result of mechanical impact, after which it stopped charging. We carry out repairs after carrying out a full diagnostic, which takes about 30 minutes.
