Many people wonder why the phone turns off by itself. Answering this question is not as simple as it seems. After all, there are many reasons for such behavior. Do not immediately panic if you are faced with this problem. Try to figure out for yourself what the true reasons for this phenomenon are. It is recommended to act by the method of elimination. But what points are worth taking a closer look at? Why does my phone turn off by itself?
Departure
Very often, our current problem appears due to the device’s battery draining. Detecting this phenomenon is not so easy. After all, few people will independently check whether the battery fits well to the mobile phone. Especially if there were no problems with this before.
To eliminate this option, remove the back panel of your mobile phone, then press the battery firmly against the phone. All that remains is to check whether the device will turn off. Yes? Then the reason is clearly something else. No? Now you have found the source of the problem.
What to do next? It is recommended that you secure the battery in some way so that it fits snugly against the contacts. In this case, they usually take the mobile phone for repair and explain what exactly needs to be fixed.
How to fix the problem
If systematic shutdowns of the smartphone are caused by mechanical damage to microcircuits and other small elements, you will not be able to solve the problem yourself. If the defect is due to a faulty battery, it is enough to purchase a new one and install it.
In case of a software failure, moisture, or incorrect charging when using a non-original cable, the problem can be solved independently. The process must be carried out as carefully as possible and according to the instructions.

Battery
Why does my phone turn off by itself? The next reason for this behavior is nothing more than a battery problem. 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 by this.
What to do in this case? Think about how long you've had your phone. Have you followed the recommendations for caring for your device's battery? 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, simply replace the faulty component. Usually, after purchasing a new battery, the phone stops turning off spontaneously.

Battery charge
The reasons don't end there. Why does my phone turn off by itself? Check the battery charge. Not the most common case, but one that occurs 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 disappears by itself. From now on, just keep an eye on your battery charge. Then you won’t have any surprises with your phone. In any case, you will be prepared to disconnect the device.
Reasons for spontaneous shutdown
The only reason for turning it off could be accidentally pressing the power button in a clothing pocket or while carrying it in a bag.
If the device turns off once at rest, then this case is not a cause for concern, but when the situation is repeated many times, then it is worth understanding the problem.
The cause must be established. They can be divided into several types:
- Software.
- Physical damage to the device.
- Incorrect use of a smartphone.
To determine what exactly the problem is, you need to gradually eliminate all possible options.
- Most devices are very temperature sensitive. To find out the temperature, you can use third-party applications. For example, CPU-Z.
CPU-Z Developer: CPUID Price: Free
- If the owner uses a bumper or plastic case to protect the device, then this may be the reason for pressing the power key. Trapped debris or an ill-fitting housing can create excessive pressure in the button area. You should remove the protection to test this option.
- Increased CPU load. Running programs in the background can interfere with rest mode and cause your device to perform unnecessary actions. If the main section overheats, the device also turns off the power to normalize the condition. Setting restrictions on how applications can run in the background can help you deal with this. You can find out details about the operation of the processor using special programs.
- Installed applications, games. Programs may have incorrectly written codes and lead to the smartphone being turned off. If some action cannot be performed, the system tries to secure the device and restore the violation. You should uninstall the application that caused the problem after installing it.
- Viruses. Malicious files use system capabilities during their operation and can command shutdowns to hide their activities. Clearing memory, deleting programs, or resetting to factory settings helps cure the device. This can be done from Safe Mode.
- RAM overload. Many high-capacity applications running simultaneously consume RAM and can cause the device to shut down or reboot. If you don’t put your smartphone into standby mode during a large number of running processes, then there shouldn’t be any difficulties.
- Battery swelling. If the battery has increased in volume, this means that its working substance has become unusable, and you should take care of purchasing a new battery. In this form, the level of supplied energy is significantly reduced, power outages may occur, which leads to regular shutdown of the device.
- Loss of contact. The places where the battery is connected to the terminals of the smartphone can oxidize and be subject to the adhesion of grease and dirt. The contact points should be cleaned. This can be done using a swab soaked in alcohol or a metal object.
- Moisture ingress. If the device does not have a level of protection of at least IP65, then it is not protected from the penetration of water into the housing, even with occasional fleeting contact.
Condensation can cause the contacts to short-circuit for a short time, causing the smartphone to turn off. To avoid such situations, do not use the device in places with high humidity. If contact has already taken place, then it is worth drying the device. To do this, open all available ports, remove the battery and leave it disassembled in a dry place (do not place it on a stove, battery or in direct sunlight!) - Software glitches. It is quite difficult to detect such a reason, but it can be solved by updating the system or resetting the settings to factory settings. Outdated versions of Android may have a bug or may no longer be supported (not receive bug fixes, security fixes).
- Physical disorders.
- If the device has been subjected to even minimal impact (fall, strong shock), then the problem may not appear externally, but contact failure may occur. This happens especially often if at the time of the incident there was a plug in one of the connectors (charger, headphones). You can determine the presence of such a violation by applying a slight force to the turned on smartphone. Compression of the housing or bending force leads to shutdown. The only solution is to contact the service center or check the contacts yourself.
If none of the proposed options reveals a problem with the device, it is better to contact a specialist. Specific procedures are most often inaccessible to the average user. Diagnostics, replacement of a failed part or flashing will allow you to return the device to normal functionality. To carry out all actions correctly, you must have special software and tools.
The phone turns itself off. Android. What to do? — the question is asked by users whose smartphones began to randomly turn off. A shutdown can occur during operation or in passive mode. In any case, the defect is associated with internal damage to the device.
It is worth noting that smartphones whose service life reaches 5-7 years begin to turn off due to a long period of use. They often function correctly for 2-3 years after the model is released. The longer the device is in use, the worse it functions. OS updates are released less frequently or the phone does not support them, programs are regularly updated and require better features, etc. All this affects the operation of the Android OS.
Viruses
Unless the reasons for such behavior lie in something more serious. Why does my phone turn itself off and on? Under such circumstances, the source of the problem is not always the device’s battery and its malfunction. Everything is much more serious.
The point is that 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 cause most gadget malfunctions. It is impossible to predict exactly how a phone will react to a particular virus.
To prevent 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 check your phone, but also “cure” it if necessary.
Android turns off while playing
There are not only games, but also other resource-intensive applications that load the phone: prolonged viewing of YouTube or videos in the player, various programs with a graphics load, and more.
Have you noticed that the phone gets quite hot? As a result, a protection may be triggered that turns off the phone and prevents it from breaking due to thermal reasons.
Try to search the Internet for information about your phone model and find out whether it is characterized by such strong heating under load, or whether this is an isolated case. There is a possibility that you will have to contact the service.
In addition, during prolonged heating, the incorrect supply of energy from the battery to the device modules may begin, resulting in a failure that causes overheating. But we'll talk about the battery a little lower.

Applications
The list of possible reasons for our current problem does not end here. Why does my Nokia or any other phone turn off? If all of the above options do not suit you, then you can think about installed programs and applications. Utilities often cause problems with your phone.
There are several options here. The first is that you have little space left on your mobile. In this case, you just need to make room. Remove a few of the most unnecessary programs or games - and the problem will disappear by itself.
The second is overloading the device. It is recommended not to open many applications at the same time, and also to clean your phone of utilities. There will definitely be something unnecessary there.
The third is the presence of malware. To correct the situation, you will have to find and eliminate the problematic utility. After this, you won’t have to wonder 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.
Damaged software
Identifying specific signs of software corruption is quite difficult. The phone may turn off or reboot for no reason, after running a certain (always the same) function, or under higher load.
Although corrupted software is a fairly rare cause of a phone turning off automatically, in this case even the user can fix it.
The first step should be to restore the device to factory settings.
If this doesn't help, try downloading the software again. This is easy to do on many phones, and manufacturers often provide easy-to-use tools. However, if the process is complex, it is still better not to do it without proper experience.
System failure
Why does my phone turn off when charging and more? The last common variant of this behavior is failures in the device’s operating system. They happen simply 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 have to figure out how to correct the situation for a long time, you simply need to reflash the gadget. It is not recommended to do this yourself. It is better to take the phone to a service center.
Usually after reflashing all problems are eliminated. If even after this nothing helps, it’s time to change your phone. After all, 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 firmware only after eliminating all of the above reasons.
Android phone turns off by itself at any percentage
Constantly turning off your Android smartphone at any percentage confirms that the battery is malfunctioning. However, it is recommended to check:
- whether the RAM is overloaded as a result of running several applications;
- are there any viruses in the system;
- whether the device is affected by external indicators (heat, cold, high humidity, temperature changes).
If none of the above causes shutdowns, then the defect is due to battery damage. What is recommended to do:
- Check the battery. If the smartphone's lid opens easily, you should check the condition of the battery. There should be no swelling, signs of corrosion, dents or cracks. Of course, the condition of a battery cannot always be determined by its external signs. Sometimes this component stops functioning as a result of manufacturing defects. In this case, it must be replaced.
- The device cannot be charged with the original charging cable. Now some popular brands are installing controllers on smartphones that cause disruption to the power supply circuit. This is done to ensure that users buy original charging cables from the manufacturer. In this case, you need to check whether the smartphone works normally after charging using the cable that came in the kit.
It is not recommended to try to repair the device if the reasons for shutdown are ambiguous.
