The mobile phone heats up when talking. Smartphone is warming up: what to do? External factors affect the device

Very often the owners of mobile devices claim that their phone tends to increase its temperature during operation. The main task is to determine the reasons (from what the phone is heated) and the consequences of this behavior.

This heating is completely normal and not a defect. However, there are a number of phone models that get very hot even after short conversations.

Possible causes and solutions

All electrical products heat up during operation. Electrical components use current for functioning and, in connection with this, they heat up.

The temperature of the mobile device may rise for the following reasons:

• tasks that consume a significant amount of current are used;
• problems in the mobile device itself;
• heating the phone is a normal situation, as heat is generated during the operation of electrical appliances.

When charging

It is quite common for your phone to get warm while charging from the mains and should not be a cause for concern. All phones heat up to varying degrees when the battery is charged.

There is a perfectly reasonable explanation for this behavior of the phone: the process of charging the battery is accompanied by heat generation, which causes the temperature of the phone to rise. It is important that this heating does not exceed the specifications of the phone manufacturer. All phones heat up when charging, some models are larger, some are smaller.

It is important to note the battery life of the phone. If the battery charge is rapidly reset to zero with minor use of the phone and its partial load, then it is recommended to check the health of the charger.

When talking

There is nothing surprising when the battery heats up when using the phone in a talk mode, since the phone's battery gives up a certain amount of energy during a conversation. In this case, an accelerated discharge of the apparatus occurs.

An additional reason for the heating of the phone is that during a call the phone is constantly in the hand, pressed against the cheek and receives a lot of heat from this. The duration of the conversation greatly affects the temperature of the phone - the battery of all lovers of long conversations heats up significantly. There is nothing criminal in this. Quite a common regular situation.

In the camera area

It is common for phone users to notice excessive heating of the phone in the camera area. In fact, the camera is not to blame here, and the reason for the heating lies in the processor, which is located in the immediate vicinity of the camera. The heating level of the processor depends on the load on the phone and the duration of its operation.

In standby

A much more dangerous signal is an increase in battery temperature in standby mode. This behavior of the battery is difficult to explain, since there is neither an increased load on the device, nor any other objective reasons. The only way to fix the problem is to replace the battery with a new one.

It is unlikely that it will be possible to save the battery; at the first signs of its malfunction, you need to get rid of it immediately. Other options can be unsafe for both the phone and its user.

Unreasonable heating of the phone can be not only due to a damaged battery. Often, heating is caused by malfunctions of other components. Alternatively, moisture gets inside the phone, in which the contacts inside the phone can oxidize and provoke small short circuits. In such a situation, cleaning of some elements is also necessary.

If there have been no special incidents with the device recently, and it is constantly warming up in standby mode, then it is extremely necessary to turn it in service center, as independently at home to answer the question "why is the phone warming up?" almost impossible.

The phone gets very hot and drains quickly

Often, the heating of the phone is accompanied by its rapid discharge. There is nothing critical in this, but the reason for thinking is quite justified.

If a the device heats up more and more often, then you should determine in which area of \u200b\u200bthe phone the temperature rises:

• when heating the back, the battery must be checked. Perhaps it is worn out and does not fully fulfill its function. Replacing the battery will help in this situation;
• when the front is heated, pay attention to the touch screen, which heats up with prolonged use. Sometimes, the heating of the front of the mobile device can be caused by incorrect processor operation.

The accelerated discharge of the apparatus is facilitated by:

3D games, video filming and heavy applications put an increased load on the video accelerator and processor. As a result, the device not only heats up, but also discharges quickly. Active operation of navigation and networking technologies like GPS, Wi-Fi, Bluetooth or 3G leads to the same effect (especially when there is no good coverage).

What to do

Try not to overload the device. To keep your smartphone cool, take breaks during long gaming sessions, downloading large files from the Web, or when working with the camera and heavy programs. Disable navigation and network modules when you don't need them.

2. There are incomplete programs on the gadget

Perhaps one or more of the installed applications contain bugs or poorly optimized code, and therefore waste system resources. Because of such programs, the processor may operate at increased power without good reason. The logical result: more heat is generated and the battery runs out faster.

What to do

Remove any unnecessary programs from your device. If the temperature rises when working with an application that is not a game, video service, or other resource-intensive program, try uninstalling it or replacing it with an analogue. Also, do not discourage the updating of individual programs, as new versions may contain bug fixes.

3. External factors affect the device

If the gadget is in direct sunlight, in a pocket, under a blanket, or in a tight case, it can also cause a rise in temperature.

Individually, these factors rarely lead to overheating. But if several of them are active at the same time and you are actively using the device, then the risk of getting burned increases markedly.

What to do

Try not to place your smartphone in the sun in hot weather. Set up an auto-lock screen to prevent your camera or other apps from accidentally launching in your pocket. Do not put the device in your pocket if your smartphone is downloading large files in the background. Remove the cover when playing games if it interferes with cooling.

4. You are charging the device incorrectly

Using a damaged or non-original charger can cause problems, including overheating. If you have a working official accessory, then the smartphone should not get very hot during charging.

The exceptions are cases when playing games, watching videos or downloading files from the Internet on the device connected to the mains. In such situations, tangible heating is provided to you.

What to do

Use only original cables and adapters. If your charger is damaged, replace it with a new one. Try not to download files, do not run games and heavy programs on a smartphone connected to the mains.

5. The gadget has problems with the system

An elevated device temperature may be the result of a malfunction in the operating system or software built into it. In addition, over time, residual files and other software debris accumulate in the OS, which can also contribute to heating.

What to do

To get started, simply restart your device and make sure the operating system is updated to the latest version available. If nothing changes, try or return to factory settings after saving important data.

6. Something is wrong with the hardware

If the above recommendations do not work, there may be a problem with the hardware of the smartphone. A factory defect or breakdown as a result of physical damage can lead, among other things, to disruption of normal heat transfer.

What to do

If you suspect a malfunction, try returning the device to the store under warranty or take it to a service center.

It so happens that the mobile device we deal with every day starts to get very hot. If this happens in certain situations (for example, after several hours of continuous play), then we will not be surprised: it is clear that the gadget's processor was under load, which is why its temperature increased. But it's another matter if the phone gets warm during its inactivity, or, say, when performing some simple operations. In this case, you need to understand what is happening and what is the reason.

In this article we will try to find out what can serve as a source of heating in the case of your device, what means an increase in the temperature of the case in a particular place, and also how to deal with the noted problem.

A bit of theory

It is not a secret for us that many processes, hidden from the human eye, take place in a working device. This is the work of the same processor, and power consumption, and graphics processing, and many others. If outwardly the smartphone looks calm, then inside it there is a series of operations that can cause, among other things, heating.

There may be several answers to the question of why the phone is heating up. To understand the real reason, you need to find out which of the device modules heats up, after which we will understand the reason for this phenomenon. And in order to know what gets hot, you need to understand where the heating occurs. It's easy to find out: pay attention to the place where the temperature rises.

There are not so many elements in a smartphone device that can heat up. These are: battery, processor and display. Only these parts can cause serious temperature rise during their operation. Because of them, the phone heats up, only the reasons are different. Read more about this in the following sections, divided by the criterion of which element gets hot.

Powerful processor

We buy devices that have 4-8 cores, capable of running any application and processing any task in a matter of milliseconds. And this gives certain positive results: working with a powerful phone is much more pleasant, because it is much less “buggy” and at the same time supports the work of colorful games and applications without any problems. Therefore, we are trying to choose just such a smartphone, without thinking about the temperature regime of such processors. And due to their high power, their average temperature is quite high. Why is this happening?

It's very simple: if the phone's hardware is involved in the calculation process, it will heat up anyway. Only, unlike a laptop, the insides of a smartphone cannot be cooled. There is no miniature fan-cooler that drives air around the “heart”. Therefore, the phone heats up, with which you will work for at least half an hour or an hour.

The degree of heating of the device also depends on how "cumbersome" in terms of performance, the tasks assigned to it are. If you play a colorful 3D game for 2 hours at maximum settings, the phone will get hotter than when you just surf the Internet.

Battery

The battery installed in the phone is the only source of power for the gadget if it is not connected to an outlet or PC. Therefore, the electricity required to operate the processor comes from here. And, as we know, a working electrical appliance can heat up if you connect it to a power source.

Therefore, if you have been working with your phone for a long time, the battery may heat up, which will start to give you discomfort.

Only in this case you need to pay attention to the degree of heating. If you understand that this is a normal temperature, since the back cover of the device is only slightly warmer than our body, you should not worry. Very soon it will cool down and return to its previous regime.

If, on the contrary, you feel that the smartphone is difficult to hold in your hands, then you need to do something. First of all, you need to know if this has happened before. If not, what caused such a reaction of the device? If this is the first time your phone gets very hot, we recommend turning it off, as it can be damaged even more. After that, you need to understand what the reason was: maybe you used non-original charging; or the battery has been replaced. There are a lot of factors affecting this, including you need to understand how quickly the phone heats up, how long it cools down, what applications were opened at the moment when you felt the temperature rise.

With all this in mind, certain conclusions need to be drawn.

Heated display

Perhaps, if you notice that your mobile device screen is heating up, you shouldn't worry about it. Most likely, you just spent too much time at your gadget, because of which the temperature of some of its components began to rise. For this reason, for example, the Samsung phone is often heated.

The degree of heating depends on the type of display used and the brightness set on it. If the problem with the rise in temperature annoys you too much, you can try to reduce the brightness; if this does not help, contact the service center. There they should tell you if this is a normal temperature for your device or not.

Charging process

It often happens that the phone heats up while charging. There is nothing surprising in this - being connected to the mains, the charging adapter begins to heat up, after which the temperature of the battery of your smartphone also rises. If, again, you can hold your device in your hands and do not burn yourself with it, you should not panic. Otherwise, we advise you to carry the phone for repair and it is advisable to refuse to use the charger so as not to harm even more. It so happens that the phone heats up when charging in the event that the power adapter fails. If this happens in your situation, be careful: it can damage the gadget.

Communication problems

As practice shows, there are a number of other situations. when the phone heats up, it discharges and shows unstable work in general. In particular, we are talking about communication problems.

You see, if a smartphone does not receive the proper signal strength, it tries to find it, connect to the network and work normally. If this cannot be done for a long time, the device uses up its battery power and starts to warm up in parallel. In this case, we recommend switching it to “Airplane mode”.

Do not harm!

If you feel a strong heating of your device for any reason, first of all try to protect yourself from unpleasant situations, such as further breakdown and failure of the phone. Disconnect it from the mains, turn it off, disconnect the battery - all these actions are aimed at rebooting the gadget, letting it cool down and starting to work normally. Only if these actions did not help get rid of the problem, begin to figure out what the matter is.

Individual working mode

Also remember that all devices are different in some way (in terms of the temperature regime). One smartphone can work with one temperature, while for another it is considered unacceptable, and vice versa. Don't be alarmed if you bought a gadget and noticed that it is heating up. Read the reviews about it: you may not be the only one facing this problem.

Every smartphone owner asked himself this question. It becomes more relevant when the heating becomes very strong, and so much so that the gadget is simply uncomfortable to hold in your hands. Let's figure out why the phone heats up, and if this is a normal phenomenon at all.

Heating is normal

How does the central processing unit work? It passes a current with a huge frequency through the semiconductors, as a result of which a strong heating of the crystal (processor shell) occurs. Therefore, any phone during operation cannot but heat up. Technologies in which processing a large number data would have occurred without generating heat, have not yet been invented. Therefore, if your phone gets warm, then this is quite normal. This phenomenon is explained by the use of modern "hardware", which is able to calculate large amounts of data.

Also, do not be surprised why the phone of one manufacturer heats up, while the other model generally remains cold. This is also possible, since different devices have different cooling systems, different processors and batteries are used. And the operating temperatures of smartphones are different. But if the gadget heats up to a temperature at which it is uncomfortable to hold it in your hands or which is felt even through the fabric of jeans, then this is abnormal. In this case, it is advisable to take it to a service center - let the masters figure out why the phone is warming up.

It is known that in any smartphone there are three main elements that are sources of heat: processor, battery, display. Each of these components generates heat during operation. It is the central processor that heats up the most.

CPU

The processor is the "heart" of any smartphone, since it is he who processes the entire amount of information and passes the data stream through itself. A chip in a stationary computer or laptop, for example, is small, but at the same time a large heatsink (aluminum plate with fins) is installed on it, and a fan is installed on the heatsink. This cooling system is necessary in order to remove the heat that is necessarily generated during the operation of the CPU. There, the problem of heat removal is easier to solve due to the larger space inside the case. However, in compact and thin phones, it is not possible to install a large heatsink or fan to remove heat, so you shouldn't be surprised why the phone gets hot.

In addition, modern smartphones (in particular, flagships) use powerful 8-core chips operating at a high frequency. Thanks to the new processors, new functions in phones, high speed and performance are available to users. However, with all this, strong heating of the central processor is possible. And although modern chips are energy-saving and efficient, they have high efficiency (that is, less energy is spent on heating each time), heat generation still takes place.

When to start worrying?

It's okay if the phone heats up after 15-20 minutes of playing - this is completely normal. The temperature may rise even when watching high definition videos or surfing the internet. Of course, it is advisable to give the phone a little rest and cool down, but there is nothing wrong with the fact of heating.

However, if the gadget is heated to such an extent that it is even unpleasant to hold it in your hands, then something is clearly wrong with it. Phones shouldn't get so hot. When developing, the manufacturer always calculates the maximum permissible heating rates, and they do not go beyond the temperature at which a person is comfortable holding a smartphone. If excessive heating occurs, then the phone must be turned off, let it cool down a little. In some cases, it is necessary to close "heavy" programs that are this moment launched. If after that the phone has cooled down, it means that the problem was precisely in the heavy load. It can be assumed that this is normal, since the processor heats up naturally. Another thing is when the phone battery gets very hot. Why is this happening? More on this later.

Software

Can the phone overheat due to poor quality software? Quite. And although the operating systems iOS, Android, Windows Mobile are of sufficient quality and well-optimized, users can install third-party antivirus programs or other applications. These utilities can start background processes that load the system. This can easily lead to heating. For example, if the antivirus constantly scans the system for viruses, and a third-party application downloads updates via 3G or 4G Internet at this time, then this will definitely lead to heating of the processor, since heavy loads are placed on it at that moment. In this case, it is quite obvious why the phone heats up quickly. So you need to monitor the software state of your smartphone and not install programs that you are not completely sure of the use or purpose of.

Display

Modern smartphone displays have huge resolutions. Even large 42 "TVs often have lower resolutions than the small 6" screen of a smartphone. This is especially true for flagships.

But the higher the display resolution, the more resources the GPU (the GPU is most often part of the main central chip) has to spend to play content that matches its resolution. Consequently, more intense heating also takes place. However, not only the chip can heat up, but the display itself. True, the temperature of the screens rarely rises significantly. Due to the large area, displays lose heat (it dissipates in the air) more intensively than they receive it. Therefore, a hot display is rare. If its temperature has really increased significantly, then there is clearly a sign of malfunction. It is advisable to return the phone to a service center.

Battery

The last component that can be the reason why the phone heats up and runs out quickly is the battery. As with the processor, it is normal for the battery to heat up as long as the temperature is within the range. And in general, you need to be vigilant with batteries, because not so long ago there was a scandal with Samsung Galaxy smartphones, in which the batteries overheated and simply exploded.

Phones usually get warm when charging. If you use a powerful charger with a current of 2A or the smartphone processor supports Quick Charge technology, then the heating will be more intense. You shouldn't worry too much here. But if the phone heats up in locked mode (without charging) or does not cool down for a long time, then there is clearly a problem. In this case, it is advisable to take it for repair.

Non-original battery

Also, the reason for heating may be a non-original battery. If the "native" battery no longer holds a charge, then buying a cheap non-original analogue is not the best solution. It may well turn out to be ineffective or even unsafe. Do not be surprised when a smartphone with non-original spare parts heats up.

Conclusion

Many are faced with the fact that the smartphone is very hot when used. However, they don't know what to do about it. Although, they are afraid that the device may burn out. If the phone gets very hot when charging, then perhaps the reason lies in the power controller, or there are oxidations that create a load. Have you noticed that there can be several reasons? Therefore, it is important to begin with diagnostics, which we will do.

Smartphone is warming up - where to start?

There are several important steps to be taken - actions to be taken:

• stop loading the device;
• remove all running applications;
• remove the smartphone from charging;
• try energy management;
• disconnect from Wi-Fi;
• try to find out the reason for the heating.

If the phone gets very hot while charging, the main reason may be in the controller. Important: if you haven't, then check the controller. If you drop it in water, then oxidation may remain on the board. They are the ones that overload your smartphone. The board needs to be cleaned. You can read the thematic post on our website.

Smartphone heats up - quickly discharges or heats up by itself

If the phone heats up and discharges quickly, then there are two conclusions. Heats up due to high load, and discharges due to wear of the battery. Try replacing the battery and not using heavy applications. If the phone heats up by itself, then look for the reason again in the loads. Here are the main reasons for the heating of the smartphone:

1. active work of the main processor;
2. high load on the graphics processor;
3. poor quality parts (do not withstand the load);
4. short circuit;
5. the presence of oxidations on the board (it happens after a liquid enters the device);
6. problems with the battery.

By the way, if the new smartphone gets very hot, then contact the seller before the warranty expires. You can still return your smartphone under warranty. If the smartphone heats up after watching a bunch of videos, then this is most likely due to the load of the GPU. Let the gadget rest for 15 minutes and everything will be fine.

The smartphone is warming up - what to do in this case?

First, find out why the Android phone is heating up. And then try to unload it. If you want to know why the Samsung Galaxy or Meizu phone is heating up, then you can unsubscribe in the comments. In the next posts we will cover these topics. In general, now you know why a smartphone can warm up!
