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.

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.
Helpful tips to prevent breakdowns
By following these tips, you will prevent screen breakdowns on Samsung phones:
- Activating the power saving mode will prevent the battery from draining quickly. Disabling unnecessary applications that are not used by the user also helps reduce energy consumption.
- Set a picture with a dark background as wallpaper. It is safer and looks stylish.
- Extend the life of your display by setting a minimum time for it to go into sleep mode after inactivity. Ideally it should be 10 seconds.
- Protect the device from moisture and drops. The screen may stop working for these reasons.
- Disable the gesture control option if you don't use it.
The reasons discussed above allow us to understand why the screen does not light up or glows white. The above tips can help prevent display screen problems from occurring.
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.
Contacting the service center
If there is no positive result, it remains to contact specialists.
Even if there is a suspicion that a component, such as a battery, has failed, do not rush to buy a new one right away so as not to waste money. Service centers have the ability to pinpoint the cause of a problem, and many offer free diagnostics. We are glad that we were able to help you solve the problem.

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.
Using charging and discharging devices
With this method of pushing, you first need to turn off the protection system - this is the controller that turned off our power supply. It needs to be unsoldered.
Then the battery (without a controller) is connected to a charge-discharge device, in this case a Turnigy Accucell 6. It performs the function of monitoring the parameters of the ongoing recovery charging process. The “TYPE” button selects the charging program.
The selection of charge parameters for various types of batteries is carried out using several presses of the “START” key. In addition, the value for the flowing current must be determined and set. The value is selected using the “+” and “-” buttons. And the indicator itself is calculated as ten percent of the nominal capacity.
When the maximum capacity value is reached, the mode changes - the process switches to the “voltage stabilization” mode. A sound signal will indicate the end of charging. And the message “FULL” will appear on the monitor.
Is it just to revive?
Another, no less strange way is freezing. Some who have already conducted similar experiments with the battery of their device claim that they were able not only to “resurrect” it, but also to increase its service life. The principle of operation of this method is to deceive the controller, which was mentioned above, because at a reduced temperature, chemical reactions in the battery slow down significantly.
Before you restore your phone's battery capacity, make sure it is not a lithium-ion battery. This type of battery may not survive such experiments.
The resuscitation process itself is as follows. To begin with, a battery discharged below the level is sent to the freezer for a period of no more than half an hour. Then charge it for a minute. In this case, turning on the phone is strictly prohibited. Next, you need to remove the battery from the device and let it warm up to room temperature on its own. There is no way to heat or rub the battery.
Once the battery reaches room temperature, it must be placed in the device and charged in the usual way. Such charging can last more than a day, in some cases even two.
Method 2
To charge an excessively discharged battery, you can use a universal charger, popularly called a “toad” or “frog”. Its cost ranges from 2-3 dollars, so in some cases it is cheaper to buy it than to go to a service center even for diagnostics.
It is important that there is at least a small residual charge left in the battery, which is not enough for the controller built into the smartphone, but is enough for a universal charger. After connecting the battery, simply charge it as indicated in the instructions for the “toad”. It is not necessary to charge it completely in this way - just let it wait half an hour for it to gain the required capacity. Then you can install it in your smartphone and continue charging using the standard method.
Method 3
This method is applicable for batteries that show no signs of life at all, i.e. their output is 0 volts. You can check this with a voltmeter, or, in its absence, using the traditional “taste” method. Don’t think that this battery is probably dead and it’s time to run to the store for a new one.
There is a method, but it requires basic electronics skills and is fraught with risks. If you reverse the polarity or use a more powerful power supply than intended, you can even explode the battery. If you are not sure, go to the service center.
You will need a 4-5 volt power supply, no more. Connect the battery from this power supply, observing the polarity, for up to 1 minute. Such an impulse will be enough for the built-in battery controller to work and begin charging using the first or second method.

Usually a smartphone or cell phone, an experienced traveler takes an external battery out of his backpack, and a city dweller looks for an outlet with his eyes. But what if you find yourself outside the city in a critical situation, and your communication device suddenly turns off? There are several sometimes controversial methods for doing this.
I warn you right away - any methods for a few minutes most often at least end in loss of battery. However, sometimes it comes down to life or health, and losing a battery is the simplest thing that can happen in such a situation. Therefore, the material will not be superfluous - at least it will make you think about providing backup power.
1. The first controversial method is to remove the battery and place it against something hot. A couple of minutes - and it allows you to turn on the phone and make a minute call to the Ministry of Emergency Situations or to friends. In any case, this method is not for smartphones - they only boot up a couple of minutes after turning on. I haven’t tried it myself, but a survival specialist I know said that this is possible with some types of batteries. Personally, I’m not sure about this, and when the time comes to throw away the next battery, I’ll try this method on it first.
2. The second controversial method is to remember how ordinary batteries are revived. To be honest, I don’t know what types of telephone batteries this works on, but there is an opinion that if you tap the battery properly on a hard object, it will allow you to make at least one short call.
3. The third option, they say, can also work. Some people believe that the battery can be charged with static electricity. That is, if you rub the battery, for example, on a fur coat for several minutes, you will gain a small amount of energy for an emergency call.
4. The fourth method works, but not on all smartphones. And it can also lead to the loss of the battery, but we are talking about an emergency, so we won’t waste time on trifles. So, we remove the battery, find a piece of paper and insert the battery into place, closing the BSI contact. In smartphones this is the middle contact.
This method allows you to “deceive” the smartphone controller, since the device now cannot determine how charged the battery is. Since the batteries cannot be discharged to 100%, the phone usually turns off when a certain minimum is reached. Accordingly, now it will turn on and you can make calls until it is completely discharged. True, after this the battery will only have to be thrown away.
In addition, fire or short circuits are likely, so be prepared for trouble. The battery may swell and crystallize. But if an emergency call can save a person’s life or health, then in comparison the loss of a smartphone or battery is a mere trifle.
Do you know any way to bring the battery back to life for at least a couple of minutes?

The operation of a lithium-ion battery is based on the internal movement of lithium ions. When a 100% charged battery is in a hot environment (in the heat), it receives an additional charge. An overcharging phenomenon occurs. This is because the lithium ions inside the battery gain additional energy from the heat (similar to the molecules in boiling water).
And vice versa, when a battery is placed in the cold, part of its energy is lost due to a decrease in the energy mobility of ions. Taking these phenomena into account, a rather ingenious, but based on quite reasonable basis, method of removing a battery from a deep discharge at home appears. Its essence is that the “dormant” battery needs to be heated. Then its ions, having received additional internal energy, will bring the readings from the terminals to a higher level.
However, you need to take into account:
- The degree of heating should correspond to the initial degree of remaining charge of the battery (that is, the deeper the discharge, the greater the heating);
- Heating should not be intense;
- Do not use open flame or heat;
- The battery should heat up all at once, and not in parts (sides).
