When fully charged, the phone turns off. Why does the phone suddenly turn off and what to do about it

Why does the phone turn off by itself? Possible causes and solutions to the problem.

Many people wonder why the phone turns off by itself. The answer to this question is not as easy as it seems. After all, there are a lot of reasons for this behavior. Do not panic immediately if you are overtaken by this problem. Try to figure out for yourself what are the true reasons for this phenomenon. It is recommended to act by the method of elimination. But which points are worth looking at? Why does the phone turn off by itself?

Departing

Very often, our today's problem appears due to the drain of the device's battery. It is not easy to detect this phenomenon. After all, few people will independently begin to check whether the battery adheres well to a mobile phone. Especially if there were no problems with this before.

To eliminate this option, remove the back cover of your mobile, then firmly press the battery against the phone. It remains only to check whether the device will be disconnected. Yes? Then the reason is clearly something else. Not? Now you have found the source of the problem.

Battery

Why does the phone turn off by itself? The next reason for this behavior is nothing more than a problem with the battery. Its malfunction almost always leads to the fact that the mobile device begins to turn off and on on its own. Don't be surprised at this.

What to do in this case? Think about how long your phone has been working. Have you followed the recommendations for caring for the battery in your device? Did you always start charging after the "problem" component was completely discharged? If not, then the reason most likely lies in the battery.

To eliminate this problem, it is enough to simply replace the faulty component. Usually, after purchasing a new battery, the phone stops automatically turning off.

Battery charge

The reasons do not end there. Why does the phone turn off by itself? Check the battery power. Not the most common case, but it does take place in practice. It is the low battery charge of the phone that causes the device to turn off.

This situation is quickly resolved. All you need to do is charge your phone and then turn it on. You will notice how the problem goes away by itself. From now on, just keep an eye on the battery charge. Then you won't have any surprises with your phone. If anything, you will be prepared to unplug the device.

Viruses

Unless the reasons for this behavior lie in something more serious. Why does the phone turn itself off and on? Under these circumstances, the device battery and its malfunction are not always the source of the problem. Everything is much more serious.

The thing is, if you notice how the phone turns off and then turns on on its own, it's time to check the device for viruses. They are the cause of most gadget malfunctions. How exactly the phone will react to a particular virus is impossible to predict.

To exclude infection, it is recommended to use special anti-virus programs for mobile devices. Or take the gadget to a service center. There they will help you not only to check the phone, but also to "cure" it if necessary.

Applications

The list of possible causes of our today's problem does not end there. Why does the Nokia phone or any other phone turn off? If all of the above options do not suit you, then you can think about the installed programs and applications. Utilities can often cause problems with your phone.

Several options are possible here. First, you have little space left on your mobile. In this case, you just need to free up space. Uninstall a few of the most unnecessary programs or games and the problem will disappear by itself.

The third is the presence of a malicious program. To fix the situation, you will have to find and fix the problematic utility. After that, you don't have to think about why the phone turns itself off and on (Samsung, Nokia or some other). After all, the problem will disappear. Its reappearance is possible when the gadget is again cluttered with programs.

System crash

Why does the phone turn off when charging and not only? The last common variant of this behavior is crashes in the operating system of the device. They happen from time to time, from viruses, and from the number of installed programs and applications. But most often, problems in the operating system are the result of incorrect firmware.

In order not to figure out how to fix the situation for a long time, you simply need to reflash the gadget. It is not recommended to do this on your own. Better to take the phone to a service center.

Usually, after flashing, all problems are eliminated. If even after that nothing helped, it's time to change your phone. Indeed, sometimes the reason lies in equipment malfunction. In such a situation, only a complete replacement of the gadget will help. Now it's clear why the phone turns off by itself. Fixing this problem is not as difficult as it seems. The main thing is to know where to start. By the way, you should think about the firmware only after excluding all of the above reasons.


Does your Samsung phone turn itself off for no particular reason? Believe me, there are reasons. You can find out them yourself, but if you are unable to do this, the service center will help you without any difficulty.

The most common reasons a Samsung phone turns itself off are:

1. The "upper" train is worn out.

Often, the device turns itself off when there is an incoming call. A short circuit that occurs as a result of a worn-out loop leads to a similar problem. The way out of this situation is to replace the worn out part with a new one.

2. Moisture has gotten under the casing of your Samsung phone.

This reason has become a classic for a long time. If you are sure that the reason for everything is the water in the phone, immediately take it to the specialists who will eliminate all breakdowns and repair your device.

3. Defective display module (for Samsung slider phones).

The display module is a ribbon that connects the motherboard and smartphone display. After some time, the part may wear out and it will need to be completely replaced.

4. Battery problems.

After dropping the device from a height, contact with water or any other contamination of the battery, the Samsung phone may have a problem such as self-shutdown. Cleaning the battery is the solution to all problems. In addition, the battery contacts may be bent, which will also cause the device to shut off. It is also important to test the battery for performance. If there are any shortcomings, the battery should be replaced.

5. The phone's flash memory or processor is defective.

The processor and "flash drive" of a Samsung phone can fail if the device falls from a height onto a hard surface, as this situation destroys the motherboard.

Does your Samsung phone or smartphone turn itself off? Just take your device to the service center, saving your time and nerves on independent attempts to fix the gadget.

Articles and Life Hacks

Owners of devices from time to time face a problem when the phone turns off unexpectedly and spontaneously during a conversation. After that, you have to take out the battery (if it is removable, if not, just reboot), turn on the phone and re-contact the interlocutor. At the same time, the charge level is sufficient for making / receiving calls and for performing other manipulations.

Reasons for disconnecting the phone while talking

  • The shutdown can be triggered by a so-called protection mechanism, which is activated to prevent a more serious problem with the machine's components.
  • The reason for the disconnection of the gadget can be a failure associated with both the software of the device and its technical part.
  • It can also happen as a result of installing a new and incorrectly working firmware version.
  • Turning off the phone during a conversation can also be caused by mechanical damage that was done earlier: the device fell or water got into it, the contacts were clogged with dust.
  • It also happens that the charge control indicator shows a false battery charge level during a call, i.e. a little (or even much) more than it actually is.

What to do if the phone turns off

  • To begin with, you still need to try to restart the device, or even better, remove the battery (if there is one in the device), turn on the phone again and make the call again.
  • Sometimes it helps to fully restore the phone's battery, or even in particularly difficult cases, replacing the original battery, which wears out over time and may well become the reason that the mobile device turns off during a conversation.

    You can check it like this: if at the moment when the phone is charging, it does not turn off during a conversation, then the problem is most likely in the faulty battery.

  • If the problem recurs, you need to take the phone to a specialist who will diagnose and establish the cause of the breakdown. The service center will help to eliminate the consequences of mechanical damage, solder the components or warm up the mobile phone microcircuit, check the battery indicator or reflash the device.
As a conclusion, I would like to say that if a forced reboot and full battery charging did not help, it is better to seek help from professionals, and not try to solve something at home, because this can only harm and aggravate the problem.

If you have problems with a wet gadget, do not connect it to the mains and stop pressing the buttons. as soon as possible and only then follow the advice in this article.

If you are sure that the inside of the smartphone is dry, feel free to continue.

1. Perform a forced restart of the device

Your phone may be on, but just frozen. In this case, the screen may be dark and unresponsive to any actions. So first try restarting your device using the hardware keys.

How to Force Restart iPhone

On iPhone SE, iPhone 6s, iPhone 6s Plus, and older, hold down the Home key along with the Top (or Side) button for 10 seconds or more until the Apple logo appears.

On iPhone 7 or iPhone 7 Plus, hold down the Side key along with the Volume Down button for 10 seconds or more until you see the Apple logo.

On an iPhone 8 or iPhone 8 Plus, hold down and immediately release the Volume Up key and then the Volume Down key. Then press and hold the side button until the Apple logo appears.

How to force restart an Android smartphone

Press and hold the power button and volume down key at the same time for 10-15 seconds. If successful, the device will restart automatically or display a menu on the screen in which you will need to select the restart command.

Some Android smartphones may restart using different buttons. If the device does not respond, search the Web for a combination of keys to restart your particular model.

2. Take out the battery and put it back

If your phone has a removable battery, remove the cover and slide the battery out of the device. Wait at least 30 seconds and replace the battery. Then try turning on the phone in the usual way - using the power button.

3. Put your phone on charge

Connect your phone to a wall outlet using the original charger. If within an hour the charging indicator does not appear on the display and you cannot turn on the device, check the integrity and cleanliness of the connector, as well as the condition of the power cable and adapter. If possible, try different outlets and replace the cable and / or adapter.

4. Reset the machine to factory settings

If the screen lights up after trying to turn it on, but the device does not boot properly, try a factory reset using the hardware buttons.

During a system reset, you may lose personal data that has not been synced to the server. Do not do this if you are afraid to erase important information.

How to reset iPhone to original settings

Connect your phone to your computer with a cable and launch iTunes. Then force restart iPhone (see step 1). When you see the Apple logo, continue to hold the buttons until the recovery mode appears on the smartphone screen.

After that, a window with further instructions should appear on the computer monitor. Click "Update" and follow the prompts from the system.

iTunes will download the correct software for your phone. If this process takes more than 15 minutes, the iPhone may exit recovery mode. In this case, hold down the forced restart buttons again and hold them until the device returns to this mode.

If the update works, the phone may turn on without resetting the system. If not, then in the iTunes window, click "Restore" to restore the factory settings.

How to reset an Android smartphone to its original settings

Make sure your smartphone is turned off and try the following reset combinations:

  • volume up key + power button;
  • volume down key + power button;
  • volume down key + volume up key + power button;
  • volume down key + power button + home key.

You need to hold down all the keys at the same time and hold them for about 10-15 seconds. After that, a special menu will appear on the screen, in which you should select the Recovery item, and then the Wipe data / factory reset command. If you do not see this command in Recovery mode, hold down the power button and momentarily press the volume up key.

After these steps, the smartphone should return to its original settings within a few minutes. If none of the key combinations work or you don't find the commands you need in the service menu, look for the reset instructions for your device model.

It happens that various models of Samsung smartphones by themselves turn off, turn on (or reboot), that is, do a spontaneous reboot. This problem is typical for devices of this brand and causes a lot of inconvenience to the owners. Let's try to understand the reasons for this behavior of Samsung. Consider:

  • Failure of software or OS;
  • Damage to internal components;
  • Service Center recommendations.

Often Samsung smartphones turn off on their own and turn on when the battery is faulty. The reason may be normal wear and tear, mechanical damage or moisture ingress on it, resulting in swelling and loss of energy capacity. For batteries, it is extremely harmful for a long time to stay in the open sun, near heat sources, or vice versa - in the cold. Incorrect charging-discharging mode leads to battery failure. Modern models require keeping the energy at the level of 40-80%, do not wait until the charge reaches zero, and do not leave the phone connected to the mains overnight. In any of these cases, in the event of a breakdown, you will have to replace the part with a new one.

Software or OS crash

The cause of spontaneous reboots can be failures in the OS or software. Perhaps there is a conflicting application on the smartphone that does not get along with the firmware, or the matter is in the firmware itself. You can calculate an incompatible program and delete it or reset all settings to factory settings using a hard reset. In the latter case, all data from the phone will be deleted. Another measure is Samsung flashing.

Under the influence of water, the battery swells - its internal structure is very sensitive to moisture and changes in environmental conditions. If a breakdown has occurred recently, the cell starts to turn off and on. At later stages, the smartphone stops turning on completely. In this case, it is better to contact the Service Center for diagnostics and troubleshooting.

Damage to internal components

Mechanical damage or wear and tear of some elements provoke Samsung smartphones to turn on and off spontaneously. For example, the wear of the cable leads to a short circuit in the power circuit, and the impact from the phone falling - to the breakdown of the processor. In any case, you will have to take your Samsung to the Service Center for diagnostics and replacement of faulty parts.

If the Samsung smartphone turns off and on by itself, it signals a serious problem that is difficult to diagnose on your own. Service workshop engineers will conduct an inspection to identify the true cause of the breakdown, consult and, if necessary, replace defective elements.
