Many Samsung smartphone owners are faced with incorrect charging of their devices. Some users cannot achieve 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 take a look at why Samsung mobile phone does not charge and what to do in a particular case.
Possible reasons for improper charging of Android
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 exposed to mechanical stress, and the battery has a limited life.
The main reasons for Samsung Galaxy charging problems are:
- mechanical damage to the supply cable;
- breakdown of the power supply or its non-compliance with the required characteristics;
- failure of the battery;
- damaged or clogged micro USB connector on the phone;
- burnout of the power controller;
- incorrect battery calibration;
- failure in work software.
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 power supply system of Samsung Galaxy
The supply chain of any smartphone can be conditionally divided into several components:
- charger (adapter);
- power cord;
- 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 undergoes frequent twists and bends, which negatively affects its service life. Therefore, first of all, check its performance. To do this, take a cord that is known to be working and try to charge your phone with it. If everything is ok, replace the cable with a new one. Fortunately, it is inexpensive.
Long term use or strong voltage fluctuations can damage the power adapter. Its check 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 amperes it delivers). If you get a low-power unit to replace the two-amp charger, then the process of fully charging your Samsung will take a very long time.
The phone may not charge well if the micro USB connector is loose or dirty. Try the following:
- Turn off your smartphone and remove the battery from it.
- Move the device to a bright light and check the output connector for dirt, dust and oxidation. If necessary, clean it with a brush, soft cloth and rubbing alcohol.
- Check if the micro USB input is loose. It is quite possible that it will need to be re-soldered.
- Turn on the gadget and connect a known working power supply to it.
- At intervals of 1-2 seconds, shake the plug in different directions. When doing this, pay close attention to the charging indicator. If it comes to life in one of the positions, the cause of the malfunction lies in the poor contact of the power cord and the micro USB connector.
Battery mobile phone has a limited service life. Therefore, with long-term use of Samsung, it is quite possible that it is he who is the source of all problems. To check the performance of the battery, you must:
If a electrical parameters the battery does not meet the standards or its appearance is in doubt, try replacing the battery with a new one.
Samsung may not charge when the power controller is out of order. It is quite difficult to check its performance at home. So it is better to entrust it to specialists.
Android software malfunctions
Charging your phone improperly can cause its software to malfunction. Due to such problems, the microcontroller will begin to misinterpret the information about the state of the battery. As a result, it will not fully charge or will 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 as follows:
After completing these steps, the old batterystats.bin file will be deleted, and a new one will be written in its place. You just have to completely discharge the Samsung, and then recharge it to 100%.
Unfortunately, today people who own Samsung phones suffer from the fact that the phone does not charge, or it charges, but with great interference. This problem has recently become quite common.
This article is for those people who also encountered this problem. If this problem is detected, you must immediately take the necessary measures, because this problem should not be left to chance. Further in the article, we will take a closer look at why this happens to the phone (does not charge) and what to do in such cases.
Cause
In the event that you try to charge the phone from a computer device or using the standard method through an outlet and the Samsung phone does not work, then the reason for this may be a malfunction of the cables. First of all, you need to carefully review all the cords on the phone. If you checked, and they turned out to be intact and working, then the reason is not in them. It is necessary to look further for the reason.
The reason may be:
- It is quite probable that the connector itself is not fixed in the phone. If this is true, 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 food controller may be broken. In the event that this is indeed the case, then it is necessary to replace it;
- If the telephone, then this indicates damage to the power circuit. This detail is quite essential in the entire system, therefore, it is necessary to carry out diagnostics before its direct repair;
- A small enough percentage may account for other problems.
It is also very likely that the problem is that the phone is quickly discharged, 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 a solution to the problems.
Elimination of breakage
First of all, it should be noted that if the problem is not in the charger, then it is best to contact a specific service center. There they will quickly carry out the necessary diagnostics and determine the cause, which you have not been able to determine.
In many centers, all the parts are in stock in order to replace the breakdown and provide the repair itself High Quality... Often in all centers the price for phone repair is acceptable. Moreover, the advantage of the services of the service centers is the provision of a guarantee for the entire phone.
A fairly common reason a phone won't charge is a breakdown of certain electronic components in the phone. In the event of such a breakdown in any service center, the person must be explained what is the reason 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 discharged.
A fairly common and common reason is the breakdown of a battery 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 the discharge of the battery when a sound or vibration signal is given. This is justified by the fact that the phone once fell, and such a breakdown happened.
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 applied not only on computers, but also on mobile devices.
There are also malfunctions inside the phone, after which the phone itself cannot recognize the charger. In this case, it is unrealistic to recognize the problem and even more so to eliminate it. Consultation and help of specialists are simply needed here.
The minimal problem is that the screen crashes. For example, after flashing the phone, the screen may not display the fact that charging is in progress, and the battery itself safely receives the necessary charge for itself.
Sometimes the smartphone breaks down for some reason, and the user is faced with the question: what to do if his beloved Samsung Galaxy A3 does not turn on. I don't want to go to the service center (SC). Do not rush to get upset, sometimes you can fix problems yourself.
Why Samsung Galaxy A3 won't turn on and what to do about it
Before running to the SC, let's look at a number of popular situations. Surprisingly, more than half of all equipment owners who turn to repair do not need it. At least their phones are intact in terms of mechanical damage. Here's what to look out for first.
Charging is broken
This component must be checked without fail, since a short circuit occurs when a defective device is connected. The phone is discharged at this moment, and therefore does not show signs of life.
The original charger on the Samsung Galaxy A3 is not one-piece, but consists of 2 parts: the actual plug case and the cord. Any of the components can be damaged
Solution: check the charging on another device or vice versa. Inspect the charger for damage, broken wires, breaks, melting of the winding (if the charger was lying somewhere near an open heat source).
Software problems
Your Samsung Galaxy A3 could simply freeze due to third party application installed on Android, or incorrect firmware.
Solution: turn off the phone for 5 minutes. If there are no results at all, then hold down the Power + Home button (key in the center) + "Volume up". The phone will go into recovery mode. If this happened, then everything is fine with him. Choose wipe data / factory reset. Confirm by clicking Yes. The phone should turn on, but the data will be deleted from the memory - keep this in mind when making your decision!
This method also helps if your smartphone loads endlessly at startup or lags a lot.
Remember: if you are advised to remove the battery to solve the problem and wait a little, you are talking to an amateur: the model has a non-removable battery!
Why is there sound, but the screen does not work
This means that the Samsung Galaxy A3 has turned on. Apparently, the display is damaged or the cable has come off, broken, burned out.
Solution: you can try to open the device and check the contacts.
Having decided to open the device, remember - this will definitely void your warranty on it. If none of the methods helped, the reason lies in the breakdown of a physical component on any board or in the wrong algorithm for carrying out the work outlined above. In this case, it is possible to establish the true cause only in the SC by conducting diagnostics.
Why the flooded Samsung Galaxy A3 smartphone does not turn on: video in 2 parts
If your phone's battery isn't charging properly, don't assume that the only problem is the battery or charging. Based on personal experience, the problem and the solution can be much easier than you think. If your smartphone or tablet is charging poorly or not charging at all, then check out 10 ways to fix these problems.
Why the device won't charge
Problems arise to varying degrees. Either the phone doesn't want to charge at all when it's plugged in, or the process is too slow. Here are some solutions.1. Bad contact
Very often, the metal coating inside the USB port and micro USB has poor contact, either through a manufacturing defect or through cable wear.
All you have to do is turn off the device, remove the battery if possible, and clean the contacts inside with something like a needle or toothpick. Do this very carefully and carefully, then insert the battery and reconnect the charger. 9 times out of 10, that's all you need to do.
2. Clean the charging port from dust and third-party fibers
Do you keep your phone in your jeans pocket? If so, then fibers may be the culprit: we have already lost count of how many times the fibers in our clothes were the cause of faulty charging.
You can also bring the charging connector back to normal condition by blowing out compressed air.
3. Try a different cable
The most fragile part of the charger is the cable. He is constantly bending, which can damage him over time.
The easiest way to diagnose a damaged cable is to take another one and see if it works properly with your device. If so, you know the original charger wire is faulty. If not, then you need to look for a solution further.
4. Use a different adapter
You have ruled out the presence of problems with the cable, then you need to check the performance of the charging device itself. This is much easier if you can pull the wire out of the adapter. We have come across many chargers where USB ports have become worn out due to endless cable plugging and unplugging.
Also check the charging / wire operation on other phones, as this will help rule out the possibility that this is a problem with your smartphone. In addition, you must make sure that the outlet is working properly.
5. Remember - safety comes first
Do not charge your gadget near water or in extremely hot or humid conditions. Do not keep the device connected to the charger for too long. Do not leave it to recharge overnight when it only needs 2-3 hours. This could damage the hardware.If you want to replace your charger or its lead, be careful: cheap third-party adapters are quite dangerous. Recently, there have been many cases of mobile phone fires due to them.
The video below captured one of these cases:
6. Replace the battery
A life battery does not last forever and after several years of use it loses its capacity. The more often you charge and discharge it, the more likely it will deteriorate. Of course, if the battery stops working after six months of use, then you need to contact the seller for a warranty.
Some defective batteries can be easily identified by appearance... If it is swollen, then it should be replaced immediately.
7. Charge from the correct source
Charging from a wall outlet will always be faster than from a computer because its USB ports have too little power. Thus, the phone charges much faster from the socket.Also, the problem may be that you are using an adapter from another device, for example, from a Bluetooth headset, which is not intended for your gadget. This adapter does not supply enough current. In the case of the latest high-end smartphones, you may have a device that supports fast charging but the adapter is not suitable.
8. Update the software or roll back to the previous version
Software updates can impair cell phone battery life, especially when an old device gets a fresh one. Android version... Newer smartphones and tablets are often optimized to take advantage of latest version BY.
If this happened to you and you cannot find a solution, try rolling back to previous version... You can, of course, first try to do full reset as the manufacturers recommend, so as not to compromise the data on the device due to old version Android.
Likewise, sometimes autonomous work smartphone can be significantly improved with the latest update.
9. Try turning it off
Using heavy applications while charging will affect the duration of the charging process. For example, if you are chatting on Skype or playing games, the device will take longer to charge.Therefore, put the device on charging in the off state or in airplane mode.
