Most weakness many Samsung phones from the Galaxy line, including the Galaxy 4 models, a charger connector. But problems arise not only because of the problematic charging socket, but also because of the phone firmware that has flown. Many owners of Galaxy phones sooner or later face the fact that the phone simply does not charge, such is the feature of mobile devices of this model.
So the charging seems to be working, but the phone does not react to it at all. I had the same problem, unfortunately, after the warranty expired.
What to do if the phone is not charging
If the phone was purchased not so long ago and its warranty period has not yet expired, then it is best to take the phone to a specialized service center specified in the warranty. Otherwise, charging the phone with other chargers, opening it or reflashing it, you risk violating the operating conditions and being left without a guarantee.
If the warranty on the phone has already ended, and the problem has just arisen. I just had such a case. Saved me then Charger selected by a sales assistant in a cell phone store. As he explained to me, the former native charger simply did not have enough power to provide a charge to the phone's battery. This measure was temporary. A couple of days later, the new charger stopped functioning again (and all the other phones in the house were charging normally from it), but the native charger again began to fit. The problem with charging was not at all in them, but in the firmware that had flown. To fix this problem, I gave the phone to my brother. Fortunately, he has been engaged in phone firmware for a long time and did everything in the best possible way. I didn't have this problem anymore.
Podrugin Galaxy 4 over time also stopped responding to charging. At first, putting some object under the phone saved me, so that the connector with the charger was raised up. But over time, this stopped helping. The firmware would not have saved here, it was in the connector itself. The place is weak and fragile. They could only help her in a phone repair shop. By replacing the broken socket in the phone with a new one, the problem was eliminated.
Faced with the problem of charging the phone, of course, it is best to contact the service center, but if this is not possible, try charging the phone with other chargers.

many owners Samsung smartphones faced with incorrect charging of their devices. Some users cannot achieve a 100% charge in any way. Others complain that this process is very slow or the gadget does not react at all when the power supply is connected to it. There may be several reasons for this, and not all of them can be eliminated at home. Let's look at why the Samsung mobile phone is not charging and what to do in a particular case.
Possible causes of incorrect Android charging
In all smartphones, the power supply circuit is the most unreliable module. This is mainly due to the fact that the charging connectors are often subjected to mechanical stress, and the battery has a limited service life.
The main reasons leading to problems with charging Samsung Galaxy are:
- mechanical damage to the supply cable;
- failure of the power supply or its non-compliance with the required characteristics;
- battery failure;
- damage or clogging of the micro USB connector on the phone;
- burnout of the power controller;
- incorrect battery calibration;
- software failure.
We will try to understand each of the above malfunctions in more detail and, if possible, eliminate it on our own.
Mechanical damage to the Samsung Galaxy power system
The supply chain of any smartphone can be conditionally divided into several components:
- charger (adapter);
- power cable;
- micro USB connector;
- battery;
- microcontroller.
In this list, the most vulnerable element is the cable that connects the gadget to the charger. This is due to the fact that during operation it is subjected to frequent twisting and bending, which adversely affects its service life. Therefore, first of all, check its performance. To do this, take a known-good cord and try to charge your phone with it. If everything is OK, replace the cable with a new one. Thankfully, it's inexpensive.
Due to prolonged use or strong voltage fluctuations, the power adapter may also fail. Its verification also consists in connecting a third-party charger to the smartphone. If the unit is damaged, buy a new product from a specialized store.
When choosing a new adapter, special attention should be paid to its output power (how many amps it produces). If you get a low-power unit to replace a two-amp charger, then the full charge process on your Samsung will take a very long time.
The phone may not charge well if the micro USB connector is loose or dirty. Try doing the following:
- Turn off your smartphone and remove the battery from it.
- Hold the device near a bright light and check the output connector for dirt, dust, and oxidation. If necessary, clean it with a brush, soft cloth and alcohol.
- Check if the micro USB input is loose. It is possible that it will need to be soldered.
- Turn on the gadget and connect a known-good power supply to it.
- With a frequency of 1-2 seconds, shake the plug in different directions. At the same time, carefully monitor the charging indicator. If it comes to life in one of the positions, the cause of the malfunction lies in poor contact between the power cord and the micro USB connector.
Battery mobile phone has a limited service life. Therefore, with prolonged use of Samsung, it is quite possible that it is he who is the source of all the problems. To check the performance of the battery, you must:
If the electrical parameters of the battery are out of specification or appearance doubtful, try replacing the battery with a new one.
Samsung may not charge with a failed power controller. Checking its performance at home is quite difficult. So it is better to entrust it to specialists.
Android software malfunctions
Improper charging of the phone can cause malfunctions in its software. Due to such problems, the microcontroller will begin to misinterpret information about the state of the battery. As a result, it will not fully charge or not respond at all to the connected power adapter.
One of these failures is a violation of the calibration of the battery. You can fix it like this:
After completing these steps, the old batterystats.bin file will be deleted, and a new one will be written in its place. You will only have to completely discharge the Samsung, and then re-charge it up to 100%.
If your battery isn't charging as it should, don't immediately assume that your charger has gone bad or your battery has gone 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 not charging at all, here are 10 ways to fix a phone that's having charging issues.
Why the phone is not charging
This problem can occur for various reasons. Either your phone does not charge at all when connected to a charger, or it charges very slowly (sometimes a little faster than the discharge process). 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 quickest, easiest, and most successful solution is a little soldering on your working machine. The problem is that often the metal surfaces inside the USB port and microUSB charger don't make good contact, either due to a manufacturing defect or because the charging cable is constantly plugged in and out.
All you need to do is turn off your device, remove the battery (if possible) and use a small object like a toothpick to pry up the small plate inside the USB port of your smartphone or tablet. Do this very carefully and gently. After that, you need to put the battery back in and connect your device to the charger. In 9 out of 10 cases, this method gives a positive result.
Remove lint, dust and candy residue
Do you carry your phone in your jeans pocket? If so, then some lint is the culprit: we've already lost count of the many cases where lint from your Levis was the cause of bad USB charging.
We have also seen phones whose charging ports were clogged with chocolate: in such cases, the phone was placed in a bag next to a package of sweets. A can of compressed air will help blow out foreign objects, and your USB connection will return to normal.
Replace cable
The most unreliable element of the charger is its cable, not the adapter that plugs into the outlet. In this situation, Apple users are especially vulnerable, since the normal life of expensive branded Lightning cables, in all likelihood, is no more than 15 minutes. Many cables are exploited quite 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. by the most in a simple way to determine the faulty cable, it will be replaced 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 problems.
Diagnosing a Suspicious Adapter
If the cable does not raise suspicion that it may be causing the problem, then it is worth checking the adapter that plugs into the outlet (especially one with a charging cable that can be disconnected). We've run into issues with numerous chargers where frequent unplugging and plugging in has loosened the USB port a bit.
We also recommend that you make sure that the same "adapter-cable" combination works on different devices - this can help you eliminate 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 performance 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 excessively hot or humid conditions. Also, do not overcharge your device; charging your phone all night when it only takes two or three hours to do so 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 the stories of exploding batteries from 2013). Better to be safe than sorry. Or burn to the ground.
If you're changing your charger or cable, beware: the internet is full of reports of cheap third-party chargers exploding in the middle of the night or over-roasting smartphones. As with any electrical equipment, make sure that everything you buy meets certain safety standards.
Replace battery
Unfortunately, batteries do not last forever, and after a few years it is already difficult for them to keep a full charge. The more often you charge and discharge them, the faster they will have to be replaced. If your battery starts to die after only 6 months, then it is probably just defective and you should file a warranty claim for a free exchange for a 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 bad 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 back cover devices and inspect the battery (if, of course, you succeed - some devices are available with sealed battery compartments).
If the back cover of the device does not open, we recommend that you put such a device with the screen up and rotate it around its axis. A swollen battery deforms 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 your battery is swollen or leaking, take it out 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, because computer USB ports are designed for a small current. The outlet can deliver twice as much current as a 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 well for you, try something else that works for your device. A charger from another phone will not always be able to provide the necessary voltage and current - for example, a charger for a Bluetooth device will be less powerful than one that is designed specifically for charging smartphones. In the case of newer premium phones, it must be a phone that supports fast charging, although the 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.
Do an upgrade or rollback
Software updates and new versions of Android can cause some damage to your battery life, especially when you upgrade your old device to the current software. Newer devices are often optimized to take advantage of the latest software by having pre-optimized hardware and software on board, while your 2 year old device has some issues getting the update.
If this happens to you and you cannot get rid of such problem, then you should roll back your device to an earlier version of Android. But remember that this is associated with great risks. Highly recommended to protect your device latest versions The software, although it is 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 greatly extended by a particular 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 features make heavy use of the battery while it is being charged, it will affect the amount of time it takes for the battery to degrade. If you're charging your device while chatting with someone on Skype at 100 percent display brightness, it's natural that the device will take longer to charge than when the screen is off and Wi-Fi and 4G are turned off.
If you want your battery to charge as quickly as possible, toggle (or turn off, respectively) Airplane Mode. Imagine that your device is immersed in a kind of energy 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 battery charge, including limiting performance before the charge drops to as little as 2 percent.
Not so long ago we already published a detailed guide on how to do battery calibration, so we will not post information again, we will only say that this is a very useful option that is worth trying before saying goodbye to your “dead” battery forever.
If nothing else helps, then you need to double check that you really have power saving mode turned on. This is the first thing you will be asked at the device manufacturer's office if you call there for help. By the way, this may be the next step for you if none of the methods described above worked for you.
