Mobile phones have become an integral attribute of every person. It’s hard to imagine life without communications, because with their help you can call or send SMS at any time, anywhere. What to do when this “assistant” stops working? You should not solve the problem yourself. If you do not have special knowledge, you will not be able to repair the device yourself. Today we will look at the question, what to do if the phone does not charge at all and does not turn on?
Such attempts can further damage the gadget, and can result in expensive and time-consuming repairs. And the most annoying thing will be if the mobile phone does not turn on and does not respond to charging due to a broken charger or a broken power button.
The only thing the owner of an android can do is remember under what circumstances it stopped working. If water gets into your Samsung phone, it may not turn on and may not become infected due to the liquid that got there. If you continue to try to charge, the board may become damaged. And this is a very serious breakdown.
Samsung won't charge
What to do if Samsung stops responding to charging? There are quite a lot of reasons here
- First you need to check the cables; perhaps they are bent somewhere. If everything is fine with them, then the reasons may be in the connector.
- Faulty charging connector. For subsequent work it must be changed.
- Your Samsung phone may not charge due to a damaged circuit board. In this case, diagnostics and determination of the extent of damage will be required, which will play an important role in equipment repair.
- Power controller failure. In this case, the only solution is to replace the damaged part.
- Samsung charges poorly and slowly. The cause may be a broken power circuit. To determine the extent of damage, diagnostics will be required. Based on it, the part that led to the malfunction will be installed.
- Other problems due to which the Samsung does not turn on or charge, which can only be identified after diagnostics.
Steps to restore charging
First, let's exclude random factors. Check the socket to see if there is current in it and whether other phones are charging normally from it. We most often encounter a lack of current in a socket or low voltage in the network at airports and train stations. At low voltage, charging is very slow.
Check the cord and adapter for mechanical damage. Broken wires, kinks, torn braiding, cracks on the case and other visible damage - stop trying to revive the faulty adapter, do not glue it with tape. A phone damaged as a result of using a broken adapter will cost more.
Check if other devices are charging from the adapter. If the adapter is faulty, take it for repair or throw it away and buy a new one, preferably a branded one. If the adapter is damaged, you cannot use it; it can seriously damage your smartphone. A sudden drop in current can completely damage electronics.
Why won't my mobile turn on?
In order to understand how to proceed further, you need to find out the causes of the malfunction. If the phone does not turn on and does not charge, then the breakdown may be hidden in any part of the equipment, which an experienced technician will help fix by making a diagnosis.
- If your smartphone does not turn on after charging, it may be due to a poor battery level. It would seem that the battery is charged and can be used for another day, but in reality it runs out in a few hours. The main reason here would be too many unnecessary features included in Android. To prevent the battery from draining and the device not to turn off at the most necessary moment, you just need to disable unnecessary functions in Android itself.
- To understand why the phone does not turn on, you need to press the “power” button for a long time; if the reason lies in the battery, then it will give a “life” signal and quickly turn off. If it is likely that the battery is simply worn out, then you will have to buy a new one.
- The Samsung may not turn on after charging due to a broken charging cable. It's very easy to check. If after a couple of minutes the smartphone does not show signs of life, it means that it is not charging, and the cause may be a breakdown of the charger. In modern smartphones, the charger, headphones, and other devices are connected through one opening. It can simply wear out, the contact pads wear out over time, they cannot be restored, only replacing the entire charging module will help. You can check if the charger is broken using another device that needs to be connected to the phone.
If the Samsung, after connecting to the charging cable, still blinks and does not work properly, then there may be two reasons.
- The first is overheating, as a result of which the battery does not receive energy.
- The second is using a charger that is not suitable for your device.
Possible reasons for Android not charging correctly
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 subject 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 power cable;
- failure of the power supply or its non-compliance with the required characteristics;
- battery failure;
- the micro USB connector on the phone is damaged or clogged;
- power controller burnout;
- incorrect battery calibration;
- software malfunction.
We will try to understand each of the above malfunctions in more detail and, if possible, eliminate it on our own.
Mechanical damage
Sometimes the phone does not charge or turn on due to falls or heavy objects hitting it. Very often the phone does not turn on because it falls on the floor. What to do if all of the above reasons do not apply, but the phone still does not turn on or charge?
You can try to remove the flash drive, SIM card or battery; perhaps some contact has come loose. If these manipulations do not help, then the breakdown is very serious and you should contact a specialist.
Which Samsung Galaxy models most often suffer from the problem?
When buying a Samsung, people often ask which models most often suffer from the problem discussed. This question is asked in order to avoid similar malfunctions in the future. Service center specialists say that such situations can occur with all devices, including A40, A50, A70 and others. The age or type of operating system is often irrelevant. This is due to the fact that the reasons why the Samsung Galaxy does not charge often lie on the surface - improper operation or mechanical damage. Problems with the battery or software are extremely rare.
How can you turn on your phone?
If the Samsung does not turn on and does not charge, you can try using the advice of Samsung technical support:
Press and hold the “volume” button down at the same time as “turn on”. Hold in this position for 10-12 seconds.
If the phone works after this, then the reason is most likely a normal device failure. If after this the Samsung does not turn on and does not charge, what should I do? In this case, the optimal solution would be to contact a good repair shop, where they will perform diagnostics using professional equipment and solve your problem. We do not recommend delving into the insides of the phone on your own; you may end up breaking things and will increase the cost of repairs.
Check the battery and charging port
Let's say the adapter is working properly, there is current, but the Samsung Galaxy is not charging. In this case, we move on to the next stage. Let's look at the smartphone itself, as far as possible at home or in the field.
Turn off the phone, open the cover and inspect the battery. Make sure it is not swollen or deformed. If the battery is swollen, it is hopelessly damaged. Only for replacement.
If there is no swelling, check the battery contacts. Checking your battery's performance is easy if you have an electrical tester. Measure the voltage at the contacts, it should be 3.5-3.8 V for a discharged battery and about 4.2 V for a charged one. If the tester readings exceed the specified limits, it is better to replace the battery. The tester is not always at hand, so this step can be skipped or performed at a repair shop.
Cleaning the Input Port
If the smartphone charges every once in a while, is capricious, or requires a certain position when charging, you need to inspect the input port. First, let's inspect the port for contamination. Shine a bright flashlight into it. If you find debris in the port, very carefully remove it with thin tweezers. In this case, it is advisable to turn off the phone and remove the battery. You can wipe the port contacts. To do this, place a thin cotton cloth lightly moistened in alcohol, vodka or acetone on the tweezers. Nail polish remover will also work. Very carefully, without pressing, wipe the contacts and let the smartphone case dry for about 10 minutes. Try charging again.
A clogged port is the cause of approximately 10% of smartphone malfunctions. Debris stuck in the port can damage the contacts and lead to more serious problems.
Mechanical damage to the charging port
Input ports are the most vulnerable part of any smartphone. Constant mechanical stress inevitably leads to wear. Over time, ports have to be replaced. Try slightly rocking the port using tweezers. If the port is loose, the tongue with the contacts is movable, and bends easily, you need to go to a workshop and have the port replaced. Most likely, a crack has formed, the contacts have been damaged and jammed. Most often, the charging port breaks when the phone falls while connected and receives a sharp shock or a tug on the cord.
If the port is mechanically damaged, the charging controller may fail, and there may be a crack on the board that prevents the signal from passing through. These breakdowns can only be diagnosed and corrected at a service center using specialized equipment.
If the phone was left without charging for a long time, the battery could be over-discharged. Modern batteries are protected against complete discharge. Leave the discharged phone on charge for 20-30 minutes. Then press and hold the power button. With a high degree of probability, the phone will respond with vibration or start charging. Hold the power button for 2 minutes and try to restart the system. The success rate is approximately 95%. If it doesn’t work, you’ll have to go to a service center and change the battery.
Battery calibration on Android
If your mobile device sees charging, but charges slowly or displays incorrect battery indicators, you can try calibrating the battery (article here, brief instructions below).
- Completely discharge the gadget until it turns off. When you try to turn it on, it should turn off immediately.
- If the battery is removable, remove it from the device and keep it separately for a few minutes.
- Reinsert the battery.
- Charge the device to 100% without turning it on.
- Remove the battery again and put it back after a while.
Unfortunately, calibration is not relevant for modern batteries.
power unit
If the cable turns out to be working, but the charger still does not perform its function, check the operation of the power supply on another smartphone or, if possible, measure the voltage at the charging output connector using a voltmeter. If there is no voltage, the unit is faulty and must be replaced.

Charge your phone while it's turned off
When we were preparing to create this material, our readers told us another way to get around the “Checking port” error. Moisture detected" and force the phone to charge. However, you should not do this if there is actually moisture left inside the port. Dry it, but do not overheat, and then proceed to the instructions below:
- Connect your Galaxy to a power adapter that you are 100 percent sure will work.
- Turn off your phone and wait until its battery begins to charge.
Did not work out? Do the same, but without turning off the gadget, but by forcefully rebooting it by holding down the Power and Volume Rocker buttons at the same time. They need to be held for approximately 10 seconds until the screen goes dark. As soon as the smartphone turns on, the battery should begin to charge.
Replace battery
Now, of course, you will tell me how to change the battery if it is practically a new Samsung A50. The fact of the matter is that it is new.
You've heard the term "factory defect". This is not a universal phenomenon, but sometimes it happens. The fact is that no one is testing them now.
She came off the assembly line, put it in a Samsung A50, sealed it and sent it to the store. Now it is more profitable for manufacturers to replace a defective one with a new one than to hire workers for tests.
This is exactly what can happen with a charge controller. It is he who controls when to charge and when not. Therefore, if it has problems, it will immediately affect the battery. That's all. Good luck.
