Sometimes the phone stops showing signs of life. What is this connected with? There are many options, from hardware problems to firmware and software. How to figure it out? Consistently follow the instructions below.

Was the device heavily discharged? If so, it will take a sufficient amount of time to restore the deep discharge. Some models require up to an hour to accumulate capacity. Try to avoid such cases, this affects the duration of work. Discharge to 20-10 percent and send your smartphone to charge. It is not recommended to keep it on charge; this will negatively affect the battery. The gadget may sometimes blink, show a black screen or various symbols. Wait half an hour, the device should turn on on its own. Advice for long-term use - if possible, do not use highscreen outside when it is cold. Low temperatures have a detrimental effect on the main components and drain the charge faster.

Check the integrity of the charging wire. If it is of poor quality, the possibility of sudden failure increases significantly. Try to buy only original wiring, then you will be sure that they will not suddenly fail.

Another option why the equipment does not turn on is that the socket (the hole where the charging plug is inserted) is broken. Possibly due to moisture, debris, damage (attempts to insert connectors not included in the kit). Replacement at a service center costs about a thousand rubles.

If the gadget falls into water, it must be removed as quickly as possible and dipped in alcohol, left for exactly a minute and placed under a hairdryer. Dry and leave alone. By taking action, there is a chance that the product can be saved.

Did you drop the phone before it completely disconnected? If yes, then there is a high probability that a qualified diagnostician can help. Damage can be of various types; an experienced technician is needed to diagnose the damaged element. We also want to warn those who like to open bottles using technology - you reduce your life activity significantly.

If you downloaded unfamiliar software before shutting down, tinkered with the settings, and you don’t have an antivirus, you need to reset it to factory settings. In most cases this helps. Please note that all data not located on removable media will be lost. In many models, when you remove the back button, you will find a bulge, the so-called Hard Reset. Clicking it will start the reset process.

If the battery is removable, remove it for a while.

The home button, the main one and sometimes the only one on the display, may be faulty. Sometimes the device shows signs of life - flickering, blinking.

If you connect your smartphone to a computer and see data on the PC, flash the device, the procedure mostly helps. If not, we strongly recommend contacting a service center. You can completely destroy the unit on your own.

As the practice of specialists shows, most often the problem that the highscreen does not turn on is that the battery is deeply discharged. Put the unit on charge, be patient, and most likely the equipment will turn on and will delight you for a long time!

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.

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.

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.

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 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.

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.

In a situation where any device, not just Android, turns off spontaneously, two reasons may be involved.

Why does Android turn itself off? Hardware problems or software glitches may be involved in this problem. Hardware problems most often occur at contact points - the battery, SIM card, keys, and the detachable connection between the screen and the circuit board.

Also, hardware-related breakdowns occur due to overheating, specifically the video processor, most often the microprocessor. Software failures are a consequence of turning off the Android smartphone, or after flashing the Android OS, or if a malicious program was installed.

To independently fix a glitch in which your Android smartphone turns off by itself, you can try two methods.

The first way is to fix hardware problems.

After using a phone or tablet for a long time, contact points are broken. Oxidation occurs at the battery terminals and device connectors, or the solder joints on the contact pads of the circuit board are destroyed.

This especially often happens after careless handling of the device: when it was thrown into water, doused with water, picked up with wet hands, dropped on the floor, pressed in a pocket, or tapped on the keys.

To try to cure yourself from a glitch in which the Android turns off by itself, you need to open the back cover of the phone and remove the battery. Next you need to clean all the battery terminals and each connector contact on the phone.

Do not rub them with sandpaper, after which they oxidize even more intensely and the contact surface is reduced due to the presence of grooves on the surface.
Cleaning should be done with a small screwdriver with cotton wool soaked in pure alcohol or contact cleaner wrapped around the end. Contact cleaner is sold in auto stores.

In addition to cleaning, you also need to slightly straighten the clamping contacts on the phone so that they are pressed against the battery terminals with greater force.

There is no need to disassemble the tablet to remove the battery. Because on tablets it is connected by a soldered connection, and a problem with the hardware cannot occur because of it. And other iron problems are difficult to figure out and eliminate, especially for a person without special education.

The second way is to remove all software errors.

A very effective method, if previously it was done manually, not through a standard update. But this method will not help if you have entered pre-installed applications or the operating system with root access and have partially or completely removed these software. Then only installing a licensed Android OS will help.

Try doing a hard reset. This procedure will probably fix the problem when the Android turns off by itself.

Turn off your phone or tablet and enter the “Android system recovery” menu.

To do this, you need to use the following key combination:

• For tablets, the key combination is as follows: you must simultaneously hold down the power off and volume down keys (for some models, volume up) for 10 seconds.
• For phones, the key combination can be similar to a tablet or like this: you need to simultaneously hold down the power off, exit to the main menu (or camera) and volume down (or volume up) keys for 10 seconds.

In general, the key combination is unique to a particular brand.

When working in the “Android System Recovery” menu, use the following prompts on the screen: highlight is the key for moving through the menu; select – key for selecting a menu item.

In this menu, you need to move to the “wipe cache partition” item and select it. Next, move to the “reboot system now” action confirmation item and select it. After this, the device will turn on again.

If the described action with deleting cache memory data did not help, then reset to factory settings. However, this will delete personal data stored in the internal memory of the device. To do this, in the system recovery menu, select “wipe data / factory reset” and confirm the action.

In the end, if using these two methods you cannot fix the glitch in which your Android turns off, then contact a specialist repair shop.

Technology has become a part of our lives, but our favorite gadgets are not without glitches from time to time. Your computer, smartphone or other everyday devices may freeze at any time. In this case, there is no need to panic or get upset - just follow the simple instructions for working with gadgets from different manufacturers.

Of course, the best option for rebooting is a removable battery. In this case, there is no need for special wisdom - you just need to take out the battery and then put it back. Because when you remove the battery, the gadget automatically turns off, and after installing the battery back, you can turn on the smartphone again.

But today, a special fashion is typical for smartphones with non-removable batteries - so such a little trick with removing the battery will no longer help us. But in fact, no difficulties should arise here either, if you know the correct procedure.

Gadget freezing is an acceptable phenomenon, so you shouldn’t be afraid of the problem, you just need to know how to solve it. In our article we will look at effective methods of emergency shutdown if it is impossible to get the battery.

First of all, it’s worth considering the question of what a non-removable battery in a phone means. As you can understand from the name itself, this is an integrated battery that cannot be removed independently.

Phone with non-removable battery

Today, gadgets with such a battery are firmly entrenched in the global mobile device market. Once upon a time, for the sake of the compactness and beauty of its devices, Apple began to use this approach, and over time, many competitors picked up the trend.

The principle of working with such a battery allows you to make the device itself much more compact, more refined, with an increased tightness of the design, better protecting the internal elements from dust, moisture and mechanical damage.

For several seconds, hold down the power button and the Home button simultaneously. Thanks to this method, you will activate an emergency reboot of the gadget, while you will be able to save all your data. Also, such a shutdown is not accompanied by a reset, which distinguishes this method from more drastic solutions.

Hold down the power button and home button at the same time

Here, too, there is no need to be afraid of any special problems. Moreover, you can use two effective methods to choose from at once - hold down the power button until you reboot. Or simultaneously press the volume rocker up and the power button.

And useful information for owners of Samsung gadgets

Press the power button for about 10–20 seconds. When you feel the vibration, you can safely let go - the gadget has “gone” to reboot.

Press the power button

Also, let's not forget about other manufacturers. You can also recall models from Explay, LG, Phillips and a number of other companies. In fact, their reboot principle is almost always identical - we just hold down the power button. If this method does not help, simultaneously press the phone's power button and the volume rocker (down or up).

Enjoy the world of digital technology and working with your favorite gadgets - we will help with this and publish useful tips for working with mobile devices. A one-time or rare freeze is not a serious problem; you just need to follow our instructions. But if such a problem occurs regularly, we still recommend contacting a specialist and sending the device for diagnostics - so as not to lose your data at the most inopportune moment in case of a freeze.

Reading time: 4 minutes

Let's look at the main reasons why an Android phone reboots on its own: what causes this and how to fix this or that problem.

It’s interesting that both Chinese “NoName” brands and famous flagships like Samsung Galaxy, HTC One, or Sony Xperia are susceptible to the flaw. Let's understand the reasons.

Mechanical damage

Let's start with the leader of all troubles - falls. This also includes blows, careless use, and the use of a smartphone for other purposes (opening bottles, hammering nails, etc.). These may seem like funny incidents, but they happen everywhere. The phone is designed for calls and work, but not for such events. Yes, there are shock-resistant models produced by companies like CAT, but there are only a few of them.

The methods of “treatment” are banal to the point of disgrace: buy a case, a bumper and a protective glass. The protection is flimsy, but periodically saves. This will protect you from damage to the motherboard, failure of the processor, memory, camera module and vital cables. But it’s still worth going to the service to accurately understand the reason for the reboots.

Firmwares and everything about them

Have you often heard from friends about “firmware”? In short, this is the replacement of the “native” smartphone OS with a more recent version, or a modified one. There are 3 options:

• official;
• custom;
• test.

If the native firmware of the device begins to slow down (too many applications, not updated for a long time, viruses, residual cache files), then you can reset the settings to factory settings - this should help in 90% of cases. It is also worth looking on the Internet to see which version of Android is current for the smartphone at the moment. The update process occurs independently without your intervention, so no skills are required.

With custom ones it’s more difficult. The only stable foreign firmware can be considered exclusively Cyanogen Mod, but this team disbanded, and the remnants of the team renamed themselves Lineage OS. Their work was truly worthy, but had one significant drawback: install the firmware at your own peril and risk. Also be prepared for reboots, CPU overheating, unstable battery, GPS, modem and other key components that affect stability.

As for the test ones, which are posted in abundance on resources like 4PDA, XDA and analogues. If you are going to use your smartphone as a “test subject” and know about the problems in advance, install it. Others are categorically not recommended to engage in such things without knowledge of the hardware. This is the easiest way to turn a device into a “brick”, not to mention cyclic reboots.

Battery

A battery, like any storage device, is designed for a certain number of charge/discharge cycles. If you constantly charge the device, sooner or later the battery will simply lose all its potential and will not hold a charge. A similar drawback is typical for Li-Pol models with a “memory effect”. The unit must be charged to 100%, and then discharged to 0. Only after this can it be charged. Li-Ion drives are free of this flaw.

Critical point: you must use only the “native” charger. The point is the current indicated on the charger. If the manufacturer indicated, for example, 1A (Ampere), then the value cannot be exceeded. Therefore, you should not use more powerful 1.5-2A analogues, since you can “kill” the battery much faster. It will simply swell. The average cycle with proper operation is limited to 1.5-2 years. Subsequently, the battery begins to lose its properties.

Another factor is contact oxidation. If moisture has accumulated inside the device, then this may be the reason for the reboot. If the battery is removable, remove it, dry the smartphone, wipe all contact pads with alcohol as carefully as possible and insert the drive after 30-60 minutes. The swollen one must be replaced.

Motherboard defects and manufacturing defects

This category is the most unstable due to the fact that there are many reasons for the breakdown of contacts, cables and other elements; only a complete analysis and testing of each component individually will help here. Often the defect is caused by a fall, “curiosity” (opening a smartphone to see how everything works and subsequent careless assembly), moisture, dust and more.

Less common is a manufacturing defect, which affects no more than 1-2 gadgets per 100,000 devices. The manufacturer often indicates this himself. Also look at thematic forums, look for a topic with your model and look for characteristic “sores”. If you haven’t dropped, drowned or opened the device, but it reboots, then something is shorting inside. It is better to send such a smartphone under warranty. You will lose time, but you will get a working analogue.

Memory problems

Installing a large number of applications is highly not recommended due to the conflict of certain files with each other. This is especially true for programs for working with cameras, GPS, data, antiviruses and cleaners. Each has its own operating algorithm, so reboots are common.
