The smartphone is heated and off. What to do if the phone is heated and quickly discharged

Very often, mobile device owners argue that their telephone during operation has a property to increase its temperature. The main task is to determine the reasons (from which the phone is heated) and the consequences of such behavior.

This heating is completely normal and is not a defect. Nevertheless, there are a number of phone models that are strongly heated even with short conversations.

Possible causes and methods of solution

All electrical products are heated when operating. Electrical nodes are used to function current and in connection with these heated.

The temperature of the mobile apparatus may increase by the following reasons:

• tasks consume a significant amount of current are used;
• malfunctions in the mobile device;
• heating of the phone is a normal situation, since the operation of electrical devices is highlighted heat.

When charging

Heating the phone when charging from the network is quite commonplace and should not cause special concern. All phones are heated to varying degrees when charging the battery.

This phone behavior has a completely reasonable explanation: the battery charge process is accompanied by heat generation, which causes an increase in telephone temperature. It is important that this heating does not exceed the regulatory parameters of the phone manufacturer. Heated when charging all phones, some models are larger, some less.

It is important to notice the duration of the functioning of the phone from the battery. If the battery charge is rapidly reset with a non-essential use of the phone and its partial load, it is recommended to check the help of the charger device.

When talking

Nothing surprisingly when heating the battery when using the phone in talk mode, there is no, since the battery gives a certain amount of Energy when talking. In this case, an accelerated discharge of the device occurs.

The additional reason for heating the phone is that during the conversation, the phone is constantly in hand, pressed against the cheek and gets a lot of heat from it. The duration of the conversation greatly affects the temperature of the phone - all lovers of long conversations, the battery is significantly heated. There is nothing criminal in it. Quite a common staff.

In the chamber area

Frequently, users of phones notice excessive heating of the phone in the chamber area. In fact, the camera is not to blame here, and the cause of heating lies in the processor, which is placed in the immediate vicinity of the camera. The processor heating level depends on the loading of the phone and the duration of work on it.

In standby

A much more dangerous signal - an increase in the temperature of the battery in standby mode. This behavior of the battery is difficult to explain, since there is neither an increased loading of the device, nor any other objective reasons. Eliminate the problem can only be replaced by a battery to a new one.

It is hardly possible to save the battery, at the first signs of its malfunction from it immediately need to get rid. Other options may be unsafe for both the phone and for its user.

Unreasonable heating of the phone may not only be due to a damaged battery. Frequently heating is due to the faults of other nodes. As an option - moisture ingress inside the phone, in which contacts inside the apparatus can oxidize and provoke small closures. In such a situation, cleaning some elements is also required.

If there were no special incidents with the device lately, and it is constantly heated in standby mode, it is extremely necessary to pass it in service centerSince independently at home answer the question "Why is the phone heats?" almost impossible.

The phone is very hot and quickly discharged

Often heating the phone is accompanied by his fast separation. There is nothing critical in this, but the reason to think quite justified.

If a The device is heated more often and more often, then it should be determined in which the temperature is growing in the temperature:

• when the back is heated, you must check the battery. It may be worn out and does not fully fulfill its function. Will help in this situation the replacement of the battery;
• when heating the front part should pay attention to touch screenwhich heats up with long work. Sometimes heating the front of the mobile device may be due to the incorrect operation of the processor.

The accelerated discharge of the device contributes:

Based on the facts described, it follows the conclusion - the phone will not be warmed only with limited loads. All elements of the phone with intensive use have a feature to radiate thermal waves, which, with essential use, can cause the unreasonable concern for the owner.

This question asked himself every owner of the smartphone. It becomes more relevant when heating becomes very strong, and so much that the gadget is just uncomfortable to hold in her hands. Let's figure it out why the phone is heated, and is this phenomenon normal at all.

Heating is normal

How does the central processor work? It passes through semiconductors with a huge frequency, resulting in a strong heating of the crystal (processor shell). Consequently, any phone can not be heated during operation. Technologies in which processing large number There would be no data without heat release, have not yet come up with. Consequently, if your phone is heated, it is quite normal. This phenomenon explains the use of modern "iron", which is able to calculate large amounts of data.

Also are not surprised why the phone is heated by one manufacturer, while the other model remains cold at all. It is also possible because different devices The differing cooling systems are implemented, various processors are used, batteries. And the working temperatures of smartphones are different. But if the gadget is heated to a temperature at which it is uncomfortable to hold in his hands or that is felt even through the tissue of jeans, it is abnormal. In this case, it is desirable to attribute it to the service center - let the masters understand why the phone is heated.

It is known that in any smartphone there are three main elements that are heat sources: processor, battery, display. Each of these components in the process of operation allocates heat. More than the rest is the central processor.

CPU

The processor is a "heart" of any smartphone, since it is he who processes the entire amount of information and skips through itself a data flow. Chip B. stationary computer or laptop, for example, has small sizeHowever, at the same time a large radiator is installed on it (aluminum plate with ribs), and the radiator is a fan. This cooling system is necessary in order to distinguish heat that will certainly stand out when the CPU is operational. There, the task of removal of heat is easier to solve because of the larger space inside the case. However, in compact and fine phones, it is not possible to install a large radiator or a fan for removal of warmth, so you should not be surprised why the phone is heated.

In addition modern smartphones (In particular, the flagships) use powerful 8-nuclear chips operating at high frequency. Thanks to new processors, new features are available to users, high speed and performance. However, with all this strong heating is possible. central processor. And although modern chips are energy-saving and effective, possess high efficiency (that is, it takes less energy to heat each time), heat release still takes place.

When to start worrying?

There is nothing terrible if after 15-20 minutes of the game the phone was heated - it is completely normal. Temperature can even increase when viewing high-resolution video or surfing on the Internet. Of course, it is advisable to give the phone a little rest and cool, but there is nothing terrible in the very fact of heating.

However, if the gadget was heated to such an extent that he was even unpleasant to hold in his hands, then something clearly something wrong with him. Phones should not heat so much. When developing, the manufacturer always calculates the maximum allowable heating norms, and they do not go beyond the temperature of which the person is comfortable to keep the smartphone. If excessive heating takes place, the phone must be turned off, give it a little cool. In some cases, it is necessary to close "heavy" programs that are currently running. If after that the phone cooled, it means that the problem was precisely in a heavy load. It can be assumed that this is normal, since the heating of the processor is natural. Another thing is when the phone battery is very hot. Why does this happen? About it a little later.

Software

Can the phone overheat due to poor-quality software? Quite. And although IOS, Android operating systems, Windows Mobile are high quality and well optimized, users can set third-party antivirus programs or other applications. These utilities can run background processes loading the system. It can easily lead to heating. For example, if the antivirus constantly scans the system for the presence of viruses, and sourid app downloads at this time update through 3G or 4G Internet, then it will absolutely will definitely lead to the heat of the processor, as it is imposed on it at this moment large loads. In this case, it is quite obvious why the phone is quickly heated. So you need to follow the program state of your smartphone and not to install programs, in the benefits or appointment of which is not fully confident.

Display

Modern smartphones displays have huge permissions. Even large 42-inch televisions often have a resolution lower than a small 6-inch smartphone screen. This is especially true of the flagships.

But the greater the resolution of the display, the more resources the graphical processor (the graphics processor is most often part of the main central chip) you have to spend on reproduction of content corresponding to its permission. Consequently, more intense heating also takes place. However, not only chip can be heated, but also the display itself. True, rare the temperature of the screens is significantly increased. Because of the large area, the displays are losing heat (it is dissipated in the air) more intense than it is obtained. Therefore, the hot display is a rare phenomenon. If its temperature really has increased significantly, then clearly there is a sign of a malfunction. It is advisable to give the phone to the service center.

Battery

The last component, which can be the reason why the phone is quickly heated and discharged is a battery. As in the case of the processor, the heating of the battery is a normal phenomenon as long as the temperature does not go beyond the boundaries of the permissible. And in general, with batteries you need to be vigilant, because the scandal with smartphones happened not so long ago Samsung Galaxyin which the batteries overheat and simply exploded.

Usually phones are heated when charging. If a powerful Current Charger with current 2a or the smartphone processor supports Quick Charge technology, then heating will be more intense. It is not particularly worried here. But if the phone in the locked mode (without charging) heats up or does not cool down, then the problem clearly takes place. In this case, it is desirable to be attributed to the repair.

Neoriginal battery

Also, the cause of heating can be a non-original battery. If the "native" battery no longer holds the charge, then buy a cheap non-original analogue - not the most the best decision. It may well be ineffective or even unsafe. Do not be surprised at the heating of the smartphone with non-original spare parts.

Conclusion

Phone heating is the most common problem among users of modern gadgets. Sometimes heating is the harmless cause of excessive use of the smartphone, but strong heating is often the cause of more serious problems with the device. So why is the phone heats?

What is the danger of overheating

The most significant risk of overheating of the smartphone is that the battery can ultimately explode. Such cases were rare, but in any case are the worst thing that can happen. It is better not to reach such a critical state, so at the first signs of excessive heating it is worth contacting the repair service. Weak heating It can also have its own manifestations in the device. For example, if the phone or tablet is heated, operating system It may be worse to cope with its tasks, because of which the gadget will be buggy and slowly work, the battery is likely to sit on this background.

The main reasons for overheating

You can distinguish several main reasons:

• Overheating processor. This may happen if a long time and often use the device, open a large number of applications, include additional modules (Bluetooth, GPS, Wi-Fi, mobile Internet).
• Phone or tablet that long is in the open sun, Begins to experience the influence of direct sunlight and overheat.
• Lack of memory, unfinished software.
• Overheating battery. This may happen in cases where defective or poor-quality chargers are used to charge the device, or if the battery itself is faulty.
• Availability of damage or manufacturing defects.

Check the operating system

The operating system is the "brain" of the smartphone, from her proper work The presence or absence of heating depends largely. With a strong overheating, first of all you need to check the serviceability of this system:

1. Check if there is no excessive amount temporary filesthat remained after any program deleted.
2. A large number of background applications Also will slow down the device. They can be closed using the task manager.
3. Smartphone firmware It can be done incorrectly, because of which the operating system can be unstable. You can solve this problem by making an update or roll back the system to the state of the previous update.
4. Check the device's memory on availability of virus. Elimination of viral software is made by special antivirus applications.

Change the screen settings

Also one of the reasons why the device can be heated is screen Settings Parameter. If this value is set to a maximum, then the phone (android, iPhone or any other) will spend much more energy and, therefore, to heat up harder. The screen brightness parameter can be changed both independently and put an automatic average value.

Great processor loading

A very often loaded processor can cause heating. A processor, working with a large number of programs, heavy games, is overloaded, which can occur overwhelming the smartphone. To reduce processor load need to reduce timewhich is spent on working with applications, let's a rest for each hour. Also reduce graphic quality In games, it will noticeably reduce energy consumption by the processor. Load only those applications that match the processor indicators.

Wireless networking

Wireless networks or communication modules - Bluetooth, 3G, Wi-Fi cause the device to work with consumption of a large amount of energy, as a result of which heating occurs. With this problem it is easy to cope, firstly, need to disablethese modules, if not used actively and constantly. Secondly, it is better periodically turn on and off them than to constantly save them in working mode. If you can use Wi-Fi, it is better to turn off the mobile Internet, it causes to spend energy stronger than the public Internet module.

Incorrect charging

In this case, the phone can greatly warm when charging. Under improper charging is meant:

• Using faulty or incompatible Charger, in this case it is usually very hot charger phone;
• Working with phone during his charging;
• Incorrect operation is impossible fully discharge Phone battery.

If you avoid the above situations, you can easily preview the heating of the phone due to improper charging.

Wrong case

Case is called to defend mobile device From various damage and scratches, its use will fix the gadget in many respects. But you need to know that the case must also be selected correctly, the phone should also be cooled as well as without it. Right covers are the so-called bumpersthat cover the easily damaged parts. Usually B. leather Czechs The phone is heated stronger and does not have the ability to cool.

Viruses and mining

The presence of viruses can also be the reason that the phone is very hot and quickly discharged during operation (this applies to Samsung smartphones, Lenovo, Asus and any other). In order to check it or not, you need to install an application to your phone that check and eliminate Viruses and malicious applications.

Flameless

If software or any applications are not inflicted by developers, then for this reason the device can also be very hot. Follow update the system or make a rollback to previous versionthen the problem will be solved.

Impact of external factors

Sometimes the smartphone can start warm under the influence direct sunlight. You should protect the device from this impact, use a gadget in the shadow or not to leave it for a long time in the sun.

Heating when talking

So that the phone does not heat up when talking, you need to turn off all additional modules and close the application tabs.

Actions during overheating

If the smartphone is periodically heated, then it is sometimes worth checking the heating temperature. To do this, install the application to the phone, for example, CPU-Z, which measures the degree of overheating. Temperature up to 45 degrees It does not go beyond the boundaries of the norm, the temperature above 50 degrees is already critical.

It is better to leave a strongly heated phone at rest for 20-30 minutes, having previously closed all applications and turning on the flight mode.

Today we will understand S. possible reasons Overheating of phones and tablets on Android and talk about how to solve the problem of heating.

Bad ventilation

Many smartphones models are known to heating when loading. This is usually observed in gadgets with a powerful stuffing. Here is the option only one - if you notice that the phone is heated, try artificially not to worsen its cooling: Temporarily remove the protective case, keep the device differently during games (without hackering it completely and not warming your palms who are so warm), do not play on The sun, by the fire or in the sauna.

Huge pressure

Number at the same time running applications, shortage of memory. The maximum load is created:

• Modern games.
• View video (especially in high quality).
• Record video to the built-in phone camera (especially in 4k).
• Applications using GPS.
• Long and intensive data transmission over Wi-Fi or Bluetooth.
• Surfing sites. Yes, the sites are now "fatty" - with large images, sound, animation and all sorts of widgets. If you scroll through several of these in different tabs, it still loads the processor and fills RAM.

The bottom line is that any device is heated under the maximum load. And if the heating is not accompanied by reboots and freezes, you do not need to panic. Just try not to interfere with the normal ventilation of the device and set the assignment tasks before it (read the last paragraph "How to prevent overheating").

If the temperature is such that the device cannot be kept in the hands, you need to contact the manufacturer's support.

Weak mobile network

Surely, you noticed that when traveling, the battery of the smartphone sits faster. And with a bad operator signal, a continuous network search may occur and as a result - tangible heating and a quick battery discharge. In certain places, smartphones can even reboot, while in the other locality they behave perfectly fine.

Worn battery

If there were no overheating problems earlier, check if the battery is fine. If the battery swelled or somehow deformed, replace it.

Several reasons immediately

Not once and not two saw such a picture: the smartphone is located in the car, constantly connected to charging, the GPS is running all the time and the stove blows on it. I wonder what he is heated from?

• Do not compile gadgets in stuffy, bad ventilated covers.
• Do not hold the working device under the sun or near other heat sources.
• When you play the game or watch the video, keep your smartphone so that it can "breathe." Do not warm it in addition to its palms.
• Do not forget that during charging the temperature rises from all devices. And if the battery is constantly charged, it can fail and start to warm even stronger.
• Try not to start too much heavy applications simultaneously so that the processor is not loaded at 100% a rAM Not fully filled. Complete unnecessary programs. Disconnect the services that do not use.
• Occasionally

Many are faced with the fact that the smartphone is very hot when used. However, what to do with it do not know. Although, afraid that the device can burn. If the phone is greatly heated when charging, then the cause lies in the power controller, or there are oxidations that create a load. Did you notice that the reasons may be somewhat? Therefore, it is important for starting to diagnose than we do.

A smartphone is heated - where to start?

You can list several important stages - the actions that need to be taken:

• stop loading the device;
• remove all running applications;
• remove smartphone with charging;
• try to regulate power consumption;
• disconnect from Wi-Fi;
• try to find out the cause of heating.

If the phone is very hot when charging, the main reason may be in the controller. IMPORTANT: If you need not, check the controller. If you drop it into water, then oxidation can remain on the board. It is they who overload your smartphone. The fee needs to be cleaned. You can familiarize yourself with the thematic post on our website.

A smartphone is heated - quickly discharged or heated by itself

If the phone is warmed and quickly discharged, then there are two outputs. Heats due to high load, and discharged due to wear rechargeable battery. Try to replace the battery and do not use hard applications. If the phone is heated by itself, then look for the reason again in the loads. Here are the main causes of the heating of the smartphone:

1. active work of the main processor;
2. high loading graphic processor;
3. low-quality parts (do not stand load);
4. short circuit;
5. the presence of oxidation on the board (sometimes after entering the fluid);
6. rechargeable problems.

By the way, if new smartphone He is very hot, contact the seller until the warranty has expired. You can also return the smartphone under warranty. If the smartphone is heated after watching the pile of rollers, then it is most likely due to the load of the graphics processor. Let the gadget of 15 minutes relax, and everything will be fine.
