LG G4 is heated and quickly discharged. The phone is heated and the battery sits down - it's time to beat the alarm

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 the processing of a large amount of data would have happened without heat release, were not yet invented. 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 service center - Let the masters disassemble 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 because of 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 graphic processor ( graphic processor Most often is 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

In the era of "smart" gadgets, a person is increasingly facing such a problem as overheating of the smartphone and its battery. Often, the causes of heating lie on the surface, it is only necessary to carefully analyze, explore and correct the work of your phone. Let's figure out why the phone is heated and on it, and find out how to deal with it.

Powerful games and applications

One of the most common causes of overheating of the mobile phone are powerful games and heavy applications, for a long time used on your Android, Windows or iOS device. Of course, if you are a lover of lighter applications and games that, often, only to "take time", then overheating for this reason your gadget is hardly threatened. However, if you are a master and tanks to play, and to drive in sports cars, it can be one of possible causes Significant overheating of the mobile device.

It is necessary to make sure that specifications Your gadget is high enough to pull all the applications that you often want to use. Need to take into account that more powerful processor It will be warm up faster, thereby preventing you about possible failures and problems in the system.

If you have a primary game for you in "heavy" games, then try to take breaks more often, give the gadget to relax and cool. You can also lower the settings of the game, but its schedule and physics will lose such manipulation, which can affect the pleasure of the process.

Backgrounds

An important component of the smartphone work is the closure of all unnecessary applicationsthat you do not use. Of course, only a large number of running applications The smartphone will not be able to lead to heating, but if you suddenly want to play a powerful game in parallel - overheating is guaranteed.

Battery and processor resources will be spent on backgroundsWhat is why the gadget battery will quickly sit down and heat up. After all, it will not be much difficult for closing them and ease your life to your device. This will contribute to the calm work of the processor and will provide the prevention that your gadgets are not heated.

Large track

Check the screen brightness on android or any other device and turn it on on automatic mode or adjust manually if necessary. Firstly, thanks to this, the battery does not eat quickly, and it will keep you charge. Secondly, it will reduce the load on the eyes. Well, thirdly, it will solve the problem with the heating of the phone.

Try to include the maximum screen brightness only during acute necessity, for example, with a rich daylight. If it is constantly turned on, and you actively use heavy applications and the Internet, then overheating cannot be avoided.

Additional connections

Features such as Bluetooth, Wi-Fi, GPS and others in the connected state take away the large percentage of charge at the gadget accumulator, as a result of which it can overheat along with the processor. To avoid this, you need to turn off these functions and thereby secure the smartphone from overheating.

Charging a mobile device

It is she who gives the load of the battery of a smartphone.

When heated the phone, its performance is significantly braked. When the device is charging, try not to touch it, let him "sleep." Smartphones are desirable to charge without extraneous interventions.

Case

At the moment there are a huge number of different covers for smartphones. They are distinguished by material, color, quality, texture and other parameters. The main function The case is the protection of the gadget from various damage, ease of use, and, of course, the case should not help heating the phone.

Almost all covers that completely overlap the back of the device, retain heat. This affects the overheating of the device. The perfect option for its cooling is a bumper case that covers only the side panels. However, these covers will not protect the phones as well as others.

Antivirus - Possible Salvation

Avoid heating device In some cases, it is possible with Installing antivirus. It is likely that viruses appeared on your device, the action of which overheats the smartphone. Check the device for malicious files And eliminate them.

If follows these tips did not bring the expected result, and you still like a questionWhy the phone is heated and because of what his battery sits down so quickly, then pay attention to the battery. The reason for overheating the device can serve its malfunction. And it can lead to the fact that try to avoid chinese fakes and use original spare parts.

Many are worried when the smartphone heats up in the process of charging or conversation. As a rule, such experiences are groundless, but it happens that strong heating is a signal to beat the alarm. Why is the phone heats up and how to deal with it? Tell me.

Why the phone is heated when charging and what to do

Heating the phone when charging is normal. It is permissible to increase the temperature of the device to 45 degrees. The value may differ depending on the material from which the smartphone is made: plastic has a smaller thermal conductivity compared to the metal.

The phone is very hot, if you use it while recharging the battery. This is a characteristic phenomenon due to heat release by battery and processor.

Note: Enhanced processor operation can provoke automatic update Applications or operating system.

We figured out that moderate heating is quite admissible. Now let's discuss, in what cases it is worth worrying:

The temperature of the device's case is so high that it is impossible to touch it.
Charging automatically turns off after the battery overheating system.
Suspicious liquid flows from the smartphone.

Such situations arise for various reasons. Often, the overheating of the battery leads to the replacement of original accessories for cheap analogues - buying a poor-quality charger or a "Chinese" battery.

Such consequences may precede the change of firmware. In addition, think three times before installing third-party custom software.

Sometimes to excessive heating of the smartphone leads short circuit Due to the fact that the battery is not tightly adjacent to the contacts, or due to corrosion of the compounds. In addition, the reason may be treacherously walking in chargerwhich has learned its time.

What if the phone is heated? If the system ever reports the full charge of the battery and at the same time it is very heated, try to recharge the smartphone to another adapter with similar parameters. Received the same result - it means the problem is not in the charger. The phone normally charged - replace the recharging adapter.

Open the back cover of the phone, get and inspect the battery. If the battery swelled, the contacts are damaged or covered with oxide, it should be replaced. Phones with an integrated (non-removable) battery are recommended to be attributed to the service center.

Note: Spoiled battery hand over disposal. As a last resort, before throwing away, pack it into a double cellophane package to reduce the harm caused by the environment.

Why the phone is heated when talking

Why is the phone heats up during recharge, but why does this happen when talking? Some people think that the current in the battery does not come, it means that there should be no reasons for heating. This is not true.

Smartphone during operation, like any device, produces heat. If communication does not take more than a minute, an increasing temperature is imperceptible, but after half an hour heating becomes more noticeable. There is nothing terrible in this: it is considered normal for most modern mobile devices. Another thing if the temperature goes beyond the framework.

The main reason for the excessive heating of the phone is to exceed the life or damage to the battery. Carefully pull it out and inspect the presence of corrosion of contacts, bloating and other defects.

Important: In no case do not open the back cover until the phone cools. There are often cases of inflammation and explosion of the battery.

Did not find anything like this? Try rebooting operating systemmaybe the problem lies in software failure. Reloading OS (rebut) on various models of phones is carried out in different ways. How exactly, you can learn in the network or dealerships.

If your phone is heated, you should not fall into a panic. Check maybe the temperature of the device within the normal range. Rear panel It is so late so much that the scrambled eggs to prepare on it? Then follow the recommendations described in the article. Good luck!

Articles and Lifehaki.

If you encountered a problem at which the phone is heated and quickly discharged, then you should not panic immediately.

First, the reasons for this can be a lot. Secondly, if the mobile phone is under warranty or you purchased it less than 2 weeks ago, then in this case you are a straight road to the salon mobile communicationswhere the cell phone was bought.

Causes of phone heating

Often, the owners of smartphones notice that their phones during work significantly increase their temperature. In this case, it is worth paying attention to which part of the mobile device is quickly heated:

When heating the back Mobile phone should be removed by the battery and see what state it is. If the battery is hot, it is desirable to replace it at all. Old battery It can be a reason for heating the phone.
When heating the front part It's all about the touch screen, which heats up from long work on it. In some cases, the cause of overheating may be incorrect work.

In other cases a mobile phone can warm up:

With long conversations.
When starting multiple programs at the same time.
With a long video view.
With prolonged location on the Internet through Wi-Fi.
When transmitting data through bluetooth.

Causes of a quick discharge phone

Having understood why the phone is heated, and the battery is quickly discharged, you can not only protect yourself from buying a new mobile phone, but also to understand how to act in order to save the charge as long as possible.

Phone quick sits for the following reasons:

Old battery that has exhausted all its cycles.
Incorrect battery charge immediately after buying a mobile phone.
After you purchased the phone, you must charge it within 15 hours in the off state.
Launched at the same time too many applications.
Constantly included bluetooth, wi-fi.
Auto-color is set at the maximum time.
High screen brightness.
Long stay on the Internet, games, view photo and video without recharging.
Faulty battery, non-original battery.

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 to the service center, since it is independently at home to answer the question "why the phone is heated?" 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.
