A bit of theory

overheating, samsung, phone

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, it is necessary 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.

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 what type of display is being used and what brightness is 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. They should tell you if this is a normal temperature for your device or not.


The battery installed in the phone is the only power source 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 worked with your phone for a long time, the battery may heat up, which will begin 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 is getting 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.

Heating components in modern smartphones

Your phone has two main components that can get very hot (these are not the only such components, but usually they are the problem):

The processor heats up under high loads, most often we are talking about games, but this is not the only option: for example, it can warm up when shooting video for a long time (since it is being encoded, which requires processor resources), some work tasks, and for some. weaker processors and for relatively simple tasks like watching a video.

In turn, the battery heats up during charging (especially when using the “Quick Charge” function and, conversely, during a rapid discharge, which, in turn, can be caused by intensive use of the processor and other components (wireless network, GPS), as well as the degree of screen brightness.

Additional nuances include:

  • Heating will be felt more at a higher ambient temperature (for example, in the summer at 30, the phone will be hotter when performing the same tasks than at room temperature 20).
  • Different processors heat up to varying degrees. For example, all other things being equal, MediaTek (MTK) processors are considered to be hotter than Qualcomm.
  • The degree to which a phone feels hot will depend on the specific model: the layout of the internal components, the design of the cooling system, the material of the case.
  • In some cases, the heat may be caused by a poor connection with the cellular operator’s network.
  • If you recently changed your phone case, this can also cause heating if it interferes with normal heat dissipation.

Powerful processor

We buy devices that have 4-8 cores that can run any application and process 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 cooler-fan that drives the 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 for 2 hours in a colorful 3D game at maximum parameters, the phone will get hotter than with simple surfing on the Internet.

Do no 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 network, turn it off, disconnect the battery. all these actions are aimed at restarting the gadget, letting it cool down and starting to work normally. Only if these actions did not help get rid of the problem, start to figure out what the matter is.

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 is not receiving 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”.

Is your smartphone warming up? We know what to do!

Slight heating of the smartphone is common for most devices under certain conditions. But if your smartphone warms up so that it is impossible to hold it in your hand, then you need to urgently sound the alarm. the device probably has a malfunction. The reasons, consequences and options for eliminating strong heating of the phone will be discussed in this article.

Modern technologies have rapidly burst into our lives in the form of smartphones, tablets and other gadgets for a long time and irrevocably. It is already impossible for many to imagine the morning without visiting the World Wide Web to find out the latest news, see the weather, and just check your email.

But, what if your smartphone or other device starts to get very hot? Instead of the usual, pleasant pastime with your gadget, the operation of the device just starts to be annoying. And, as you know, morning largely determines the mood that you will have throughout the day. What is the reason for the heating of the phone? Where is the problem? Let’s try to figure it out in order to return the correct operation of the gadget and the good mood of the user.

There can be many reasons for the unusually strong heating of a smartphone, here are the most common:

    You have a pretty powerful device. If you are the lucky owner of an expensive smartphone, then it is likely that it has an advanced “filling”, which generates a lot of heat under serious loads. In this case, it is often not the processor that heats up very specifically that is to blame, but the design mistakes of the smartphone manufacturer, who did not organize a good cooling system. You are an advanced gamer and a bunch of new games are installed on your phone. No matter how good the smartphone is in terms of gaming, long-term work with demanding applications leads to heating. Application work in the background. Often, smartphone users do not turn off background features such as Bluetooth, Wi-Fi, GPS, mobile internet, default programs, etc. It is advisable to simply turn off applications that are not in use, this will save the battery level and avoid strong heating of the phone. Heavy loads and continuous work without interruption. Even the hardware needs to rest a little, working without interruptions simply exhausts your device, and it starts to overheat. Communication problems. In remote places, where there is poor network coverage, a special module that is responsible for communication begins to work more intensively, simultaneously warming up. Software problems. The phone may warm up due to the “clumsy” firmware, which was created by a non-professional. The reason for the heating can also be an official update of the system (this happens very rarely, but it is possible). Malfunctions of the hardware of the smartphone. All sorts of problems with the “hardware” of a smartphone or tablet (processor, memory modules, etc.) often cause overheating, but they can only be identified in a service center. It is not worth poking around in the “insides” of the device without special skills. Poor ventilation. While in a bag or tight. a smartphone running various tasks in the background may well get warm. Here, the processor heats up, which in a closed space has nowhere to remove heat, and heat also emanates from your body. Ingress of water or other liquid. If you are used to listening to music on your smartphone while in the bathroom or just accidentally poured water on it, it will most likely simply fail. However, moisture can cause your smartphone to get very hot. The tips are simple: try to dry it using a plate of rice, or even better send the device for treatment to specialists. Case. A smartphone in a case, and even under load in hot weather, is the same as playing sports in a fur coat. Most covers, which are made of thick materials, generate heat because heat dissipation is slower. But if you are used to protective covers, then try to find a solution made of thin material, with ventilation holes. Defective battery. Often it is the battery that is the source of high temperatures. Naturally, a serviceable battery, if it should, is not very hot even during charging. An old, worn out battery loses the ability to regulate the energy consumed by the smartphone from the network. Which leads to overheating of the device. Do not put off here. replace the battery yourself or contact the SC.

When it was possible to identify the reasons for the strong heating of the smartphone, you can try to fix the problem yourself. Here are some guidelines to help you overcome extreme heat:

    Overheating of the processor. This problem is quite simple to solve. We remove or disable unnecessary applications and processes so that they do not hang in the background. In principle, the work of several processes will not bring any harm to a smartphone (for that, it is a smartphone), but the abundance of useless background tasks, of course, will affect its work. It is advisable to periodically clean up background processes and remove unnecessary applications. Often, leaving the phone alone for a while is enough to cool the processor down. A number of chipset models, it should be noted, are themselves prone to strong heating. there’s nothing you can do about it. Heating associated with the mobile network. The constant search for a network, which a smartphone often does, causes the smartphone to heat up, albeit small, but nevertheless. As a rule, the module responsible for finding the network is especially hot in remote places, where it has to work several times more intensively. If it is possible to use Wi-Fi, then it is better to use this interface. When this is not possible, set the priority for the network (2G, 3G, 4G), which has the best coverage in the place of your stay, so that the smartphone does not constantly switch between them. Long screen on. The display can sometimes get warm too, for example when you are playing games or watching a movie. Just give your gadget a little rest. If the heating is strong, you need to visit the service center. In case of incomplete or incorrectly updated software that causes heating, the way out is to rollback to previous versions. It is advisable to use only trusted sources for downloading or official firmware and updates. Overheating caused by direct sunlight, constant stay in a or tight case, next to heaters. Everything is trite here: do not leave the device in places where there are objects that will contribute to heating. Remove the case when your smartphone is charging or playing with it. Overheating caused by improper charging. Remember, when charging your phone, you should only use a quality charger. It is advisable not to load the smartphone with various tasks when it is connected to the mains. Overheating caused by system problems. Various errors in the operation of the system can also cause heating. To get started, just try to reboot your device, you should see when the last licensed updates were installed. If the smartphone continues to heat up after restarting, then restore the device to factory settings, saving important information before that. If this does not solve the problem, contact the service center.

Another thing you should never forget is the rules and regulations that are set by the manufacturer of your gadget, violation of which sometimes leads to overheating. Here are the standard rules and regulations established by almost all phone manufacturers, which it is advisable to adhere to:

    do not talk for more than 30 minutes in a row; constant use of powerful applications; constant viewing of video in HD quality; do not use Bluetooth and Wi-Fi all the time, it is advisable to turn off these functions when you are not using them.

But in the case when you are doing everything correctly, do not overload the phone with applications and constant use, and strong heating is still observed, then it is better to turn to the help of the service center professionals. Most likely, overheating is caused by errors in the manufacture of your phone or other device.

In order to solve any problem, you need to unequivocally determine the cause of its occurrence. So it is with heating the device. To understand what is behind the overheating of the phone, first, just take it in your hand and try to understand which part is warming up the most. All of the causes and remedies described above should deal with this common problem. And treat your gadget with love so that it works for a long time and correctly!

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.

In what cases is the fact that the phone heats up quickly normally

First, about the scenarios when the phone’s heating should not bother you much, since it is quite normal:

Samsung On Next & j7 Prime Device Overheating Solution

  • You are playing a hard game. Especially if the phone is being charged at the same time. over, some games that do not have excellent graphics are poorly optimized, which also puts a strain on the processor of your phone. Also, do not be surprised that these games drain the battery very quickly, see Android drains fast, iPhone drains fast.
  • You use your phone as a navigator, especially if it happens in the car and the phone is connected to a charger.
  • You are working with some kind of applications that require significant computing resources. These are now available for both Android and iPhone. As a rule, this is something related to graphics and video, but there may be other options, for example, with intensive downloading of something in a torrent client, the device will also heat up, and, of course, when performing various performance tests.
  • Several applications or a large application are being updated at once: this is a rather energy-intensive process. Also, if your phone has a significant number of automatic syncing apps installed, it may cause heating.
  • The phone is in charge, especially if you use functions like Quick Charge. However, in this case, a “healthy” phone usually does not get hot, but rather very warm (35-45 degrees).
  • Calls while charging can make the temperature from step 4 above.
  • You are in an area where the phone constantly loses and finds a network again or the type of connection changes (2G / 3G / LTE).
  • You use the phone in the sun, in the heat, especially if energy-intensive operations are performed while the phone is being charged (everything described in this paragraph should be avoided if possible, this is undesirable for your device).

As a rule, in these situations, the phenomenon is short-lived (except for games) and when the factor that affects the use of the processor, the charge and discharge of the battery disappears, the phone temperature quickly returns to normal.

Heating components in modern smartphones

Your phone has two main components that can get very hot (these are not the only such components, but usually they are the problem):

The processor heats up under high loads, most often we are talking about games, but this is not the only option: for example, it can warm up when shooting video for a long time (since it is being encoded, which requires processor resources), some work tasks, and for some. weaker processors and for relatively simple tasks like watching a video.

In turn, the battery heats up during charging (especially when using the “Quick Charge” function and, conversely, during a rapid discharge, which, in turn, can be caused by intensive use of the processor and other components (wireless network, GPS), as well as the degree of screen brightness.

Additional nuances include:

  • Heating will be felt more at a higher ambient temperature (for example, in the summer at 30, the phone will be hotter when performing the same tasks than at room temperature 20).
  • Different processors heat up to varying degrees. For example, all other things being equal, MediaTek (MTK) processors are considered to be hotter than Qualcomm.
  • The degree to which a phone feels hot will depend on the specific model: the layout of the internal components, the design of the cooling system, the material of the case.
  • In some cases, the heat may be caused by a poor connection with the cellular operator’s network.
  • If you recently changed your phone case, this can also cause heating if it interferes with normal heat dissipation.

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 cleaning your phone or returning to factory settings after saving important data.

There are incomplete programs on the gadget

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

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 Do not put the device in your if your smartphone is downloading large files in the background. Remove the cover when playing games if it interferes with cooling.

External factors affect the device

If the gadget is in direct sunlight, in a. 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.

When the phone heats up can be a concern and what to do

If there are no obvious factors that could cause the phone to warm up, this may indicate undesirable phenomena.

If the phone heats up when it is just lying (not charging), while there are no app updates, or downloading something from the Internet, it can be assumed that some application (it is possible that it is malicious) continues to work in the background.

Lately, these have often been cryptocurrency miners integrated into various free applications, but there may be other unwanted applications as well. To test this possibility, you can restart your Android phone in Safe Mode (all third-party apps will be disabled).

If at the same time the heating disappeared, try to guess what exactly you installed recently, what could have affected this, and also study the battery report in the settings (see which applications are most consuming the battery in the parameters).

Sometimes the “culprit” is not malicious applications, but antiviruses or programs for cleaning memory: check if the problem persists if you disable or remove them.

Another cause for concern: the phone became very hot after replacing some hardware components (battery, charging connector) or after situations when something could damage these components (for example, after the smartphone fell into water). At the same time, keep in mind that those batteries that you buy yourself or are installed under the visible “new original” very often are not such and by themselves very quickly discharge and heat up differently than the battery from the manufacturer did.

  • If a phone with disabled Wi-Fi and Bluetooth wireless networks is not connected to a charger heats up, this is not normal. We are looking for a problem: an unwanted, malfunctioning application or hardware malfunctions.
  • When the phone is warming up on charging and at the same time you are doing something on it. heating is natural.
  • If the phone gets very hot and quickly discharges during some games or when using certain programs, but this does not happen during other operations, this is usually normal.
  • If you’ve just got a new phone and it feels hotter to use than your old phone, it could be due to differences in hardware components, materials, and cooling approach.

Aren’t there any utilities to control the temperature of the processor and smartphone battery like in laptops??

Yes, AIDA64 shows for example. But only there is little for many models: somewhere only the temperature of the battery is displayed, somewhere else there is some kind of sensor, somewhere is empty. Those. not quite like on a laptop or PC.

Well, it’s still much better than feeling with your hands in the summer when everything is warm or heated.

Slight heat is common on a mobile device. But if the smartphone heats up too often or starts to burn your hands, it’s time to take action.

No moisture and short circuits

The reasons why the phone heats up may be moisture getting into the case or a short circuit. Both things are unpleasant. And a short circuit can happen precisely because of moisture. Therefore, it is so important to take care of your phone. If you fail to save, it is best to contact a service center. It is unlikely that it will be possible to eliminate phone overheating caused by these reasons on your own.

The more powerful the hotter

There is real power hidden under the body of a modern smartphone. 6-core processor in Apple iPhone X. Octa-core. Huawei Honor 10. Samsung Galaxy S8 and S8 are equipped with a 10-core processor. A real power race among smartphone manufacturers. They put this power in a small case, where the cooling system does not cope with the assigned duties.

She copes while using the power of the processor to a minimum. Calls, communication in instant messengers, work with documents or e-mail. But as soon as the user starts playing a modern game, watching a movie in good quality, the situation changes, the phone heats up.

If it heats up for several hours, then it may cause the system to malfunction. Constant overheating of the smartphone. to a significant reduction in operating time without recharging: two times in six months. The prospect is unattractive. This can be avoided by simply letting the phone rest. After one movie, pause before watching another. After the mission has been completed in the game, also take a timeout. The processor will rest and be ready for new tasks. If the phone will not cool down very actively, you can turn it off for a while. Then turn it on. This will help the processor recover faster.

This insidious battery

It is the battery that can be the weak link in a smartphone. Why does my phone get hot while charging? This is one of the most common questions. There are different answers to it.

First of all, the charger itself and the wire to it. They must be “native” or purchased from authorized dealers. Chinese chargers for 100 rubles are not very reliable. They can cause the phone to heat up.

Another point is the battery itself. When charging, it can even swell, quickly consume energy. This means that you need to change the battery to avoid big trouble.

Modern smartphones charge very quickly. Literally an hour, and the device will be on full alert. If, of course, you leave him alone for this hour. Don’t play. Don’t call. Do not surf the Internet. Any activity during charging may cause the case to heat up.

Apps, viruses, navigation

The phone gets very hot due to numerous applications, smart tips installed in it. We were just thinking, but the smartphone suggested how to get to the bus stop faster, from which point it is better to call a taxi, at which pharmacy the medicine is cheaper.

We open a bunch of applications every day. They remain hanging in our phone, if they are not forcibly closed. By default, navigation works in the smartphone. He is connected to the mobile Internet, at the same time looking for wi-fi. The phone also heats up due to these activities. The solution to this problem is simple. It is enough to close unused applications, turn off navigation, if it is not needed, use wi-fi. It is necessary to systematically check the contents of the phone for viruses, download applications only from official sources. Viruses can send spam from your smartphone, which you don’t even know about. This activity also causes the machine to overheat. If this happens, you should check the phone for viruses again. By the way, the antivirus on the Android operating system must be installed.

Our review will help you choose the best antivirus.

How to Fix Overheating Problem in Samsung A50, A70, A80, A20, A10, A50s, M30s

If the heating has not stopped, you need to remove all applications, games that have been installed recently. If this does not help, you will have to reset the smartphone to factory settings. Reflash phone.

Display brightness is a path to overheating

A bright picture is always pleasing to the eye. But the higher the display brightness, the faster the battery is consumed, the more the phone works. Reverse side of the medal high resolution clip art.

It’s easy to avoid this. It is enough to reduce the brightness of the display. Use it half-heartedly. True, not everyone agrees to this. Especially lovers of sharp graphics and bright pictures.

Correct case

Not only the inner filling, but also the outer shell can cause the phone to overheat. There are no trifles in this business. The hottest, oddly enough, are leather cases. It is the smartphone corked into the skin that starts to warm up faster. And an ordinary plastic bumper will not lead to this problem.

The advice is simple. Take a closer look at the clothes of your device. If the phone heats up. change the case.

Why does the phone get warm, how to avoid it

According to statistics, every third person is faced with the heating of the phone. The situation is unpleasant given the stories of exploding batteries. Yes, and using such a gadget is not comfortable. To fix this problem, you need to understand why the phone is heating up. The reasons can be very different. from accidental (the body warmed up in the sun) to constructive ones, which can only be solved by changing the smartphone. But do not worry: in most cases, the problem can be fixed in simpler ways, which we will talk about below.

Factory defect and other damage

The smartphone may be too hot due to a factory defect. Any internal malfunction leads to overheating. Think about how many times you dropped your phone. Enough for jewelry designs. Just one detached contact can lead to a real disaster. And here you should urgently contact a specialist. As in the case when a specific place in the device heats up: the corner of the case, the center of the display, the charging socket, the camera. The wizard will tell you how to cool the phone.

Smartphones get warm for a variety of reasons. A too brightly set screen, using the functions of the device to the maximum, viruses, left-hand chargers, unreliable sites and applications. all this can lead to overheating of the phone. Simple care and attention will help you avoid it, use all the capabilities of your smartphone longer.

Resolution optimization

Modern smartphones have monitors with incredible resolution, clarity and brightness. At the same time, the user himself is not always able to distinguish super high resolution from just good, medium or even low. This is especially true for games and 3D graphics. The user is physically unable to see the ultra-high detail of small details on a tiny handheld device. But the processor and graphics accelerator are working at full capacity, working through this unnecessary detail in most cases. Change the resolution on Samsung Galaxy from maximum to medium. you will not lose quality, but will almost double the battery life on a single charge. You can change it through the menu “Settings display display resolution”

Optimizing brightness

The maximum screen brightness is required for operation in bright sunlight. Your smartphone needs to shine brighter than the sun to be comfortable. This is the only case where maximum brightness is really needed. In all other cases, reduce the brightness to medium values. Especially in the dark. A screen that is too bright can not only drain your battery but also irritate your eyes.

To change, go to the “screen settings” and move the slider to comfortable values.

The main reasons why the battery runs out quickly:

  • Incorrect setting of phone modes, a large number of power-consuming applications, gestures, maximum brightness settings. Solved by optimizing tasks and reducing energy consumption.
  • Incorrect firmware version, which leads to excessive power consumption, improper operation of devices, and may even harm hardware. The same applies to viruses and third-party resident programs that add their own energy-intensive processes, mining, data processing, and so on.
  • Physical damage and deterioration of the battery. The battery will wear out after about 300.600 recharges. This is approximately 1-2 years of service. A worn out battery just needs to be replaced. It cannot be repaired and restored.

Damage to the battery is not uncommon when charging with incorrect, low-quality devices with a current supply in a different mode and a different voltage. This explains the manufacturer’s constant reminders that you need to recharge your smartphone only through a native charger, adapted specifically to this type of device. On trains, recharging sockets are even provided with special signs stating that if the phones are damaged due to improper supply of current, the railway is not responsible. To check the capacity of the battery, special equipment is used; this can be done in any, better than a branded, workshop.

What is considered too fast discharge of a Samsung Galaxy smartphone?

Perhaps you are used to old Nokia and are sure that the phone should hold a charge for a week or a whole month. Two in standby mode. A smartphone, even with a huge battery, discharges much faster and sits down even in standby mode due to the large number of active tasks launched in automatic mode.

Too fast discharge should be considered if the Samsung Galaxy phone is completely discharged after 2-6 hours of operation or in a day with a shutdown for a long time. Note. There are games and graphics applications that can really drain all the energy of a smartphone in 3-4 hours. For such situations, use an external rechargeable battery.

The power consumption of modern phones is quite serious. a powerful processor, a video card, support for large memory, video cameras, a screen with a colossal resolution, support for external sensors, networks, synchronization with various devices. If the phone runs out of power during a day of active work, this is normal. In standby mode, Smart continues to actively consume energy and search for networks.

Disable continuous search for networks and compatible hardware

This monitoring drains resources very seriously. Turn on airplane mode. This option will save at least 30% charge.

Disable Bluetooth search via the “connection settings advanced settings” menu. When you need to connect the device. turn on the search, connect the device and turn off the search again.

Power saving mode

The new Samsung Galaxy has a power saving feature. You can use the function through the menu “battery settings”.

Disable unnecessary gestures

Without a doubt, gesture control is very convenient. And you almost certainly installed them all. to try and enjoy them to the fullest. Excellent. Now turn off those gestures that you are not using. To do this, go to the settings additional functions.

Optimizing processes to save energy

The first step is to choose a dark or neutral screen theme with minimal or disabled animation. Theme animations, smooth scrolling, stylus animations, vibrations with each press consume a lot of energy. Remove unnecessary vibrations and animations.

Use all methods from the list at the same time, until you reach acceptable values.

Overheating of the battery

A common reason for a hot smartphone is that while charging, owners use the phone and thus wear out the battery.

In addition, it is recommended to avoid the use of fake chargers and cables. the devices, by their incorrect operation, can harm the phone’s operation.

The reason for heating Android devices can be liquid, for example, raindrops, which, when interacting with an old charger, create a short circuit.

The phone can become hot due to an “old” battery. If, after replacing the battery, the smartphone does not maintain the standard temperature, then this is not the problem. We recommend contacting the service for troubleshooting.

What to do if your smartphone overheats

Your phone can overheat for a variety of reasons, from non-stop CPU operation to hot weather conditions. Most owners of mobile devices of different operating systems have encountered this phenomenon.

You cannot put up with the constant heating of the phone, because its battery can explode unexpectedly. We will tell you why your smartphone overheats and how to avoid it.


The accessory increases the temperature of the device and can become very hot. In the cold season, it protects the phone from turning off and falling, but in hot weather it is worth taking it off.

Lack of network

A hard working communication module can provoke a high temperature of a smartphone, which spends a lot of effort when looking for a good signal. He does this especially actively on the train and in remote places where there is no communication. Then you need to turn off the smartphone or put the mode “on the plane”.

What should be the temperature of the phone?

You can determine the current heating level of your smartphone using special applications from Google Play, available for free. Well-known mobile temperature detection services include AIDA64, CPU-Z and Cooler Master. Internal sensors help you analyze the status of your phone and display the information you need.

Most often, the processor, display or battery overheats in phones. Let’s list the external factors affecting overheating:

How to cool the phone?

First, try removing the cover that can trap heat. Then turn on airplane mode and turn off unnecessary features such as Bluetooth, Wi-Fi, or cellular signal search. This will help speed up the temperature drop of your phone.

Never put a hot appliance in the refrigerator or freezer. Extreme temperatures are detrimental and can cause irreparable harm to your mobile phone.

iPhones and Android devices are designed to be used with a temperature plug between 0 and 35 degrees Celsius, so degrees outside of the range can negatively affect the performance of your phone or hardware. When your phone overheats due to direct sunlight or heat, you need to move it to a darker and cooler place.

Reasons for processor overheating

Modern smartphones are equipped with multi-core processors similar to desktop ones, albeit without an active cooling system. They improve the performance of devices and allow you to quickly install applications, use high-speed networks, Wi-fi networks, download web pages and high-definition videos. Due to such a large amount of applications running in the background, the smartphone can also overheat. Disable anything you don’t use and close open tabs.

Samsung’s flawed products are a prime example of stories with problem processors.

Many active applications in the background

Any smartphone is capable of keeping several running applications in the background, which can take away part of its resources and over time it overheats. It is necessary to ensure that there are no unnecessary programs in the background.

Most often, the problem lies in the utilities that, according to the developers, maintain the system (clear the cache, remove unnecessary garbage, or “kill” unnecessary processes). Samsung has its own feature. Optimization. it works well, so there is no need for third-party utilities.

First of all, remove all third-party analogues of “Optimization”, such as Clean Master or CCleaner. Next, open the phone settings and go to the “Optimization” section.

If the reason for the overheating of the device is in any of the installed applications, then in the battery menu you will see a warning in the form of an exclamation mark. Tap on it and you will see recommendations for eliminating the causes of fast battery charging, which in this case is the reason for the strong heating of the Samsung Galaxy.

Galaxy gets very hot while charging

If the phone heats up while charging, then there is nothing strange about this, especially if you use fast charging for this. The main thing is to let the heat leave the gadget so that it does not overheat. Users make the mistake of leaving the device while it is charging, such as on a bed or worse, under a pillow, so make sure it rests on a hard surface that will absorb heat rather than store it.

Charging your phone wirelessly can generate even more heat. For this reason, Samsung wireless chargers are equipped with active cooling systems. A cooler is installed inside, which turns on when a certain temperature level of the smartphone is reached.

If your Samsung Galaxy heats up so much that it turns itself off, then we can recommend disabling the fast charging function. The manufacturer has provided the opportunity in the proprietary software. To do this, follow the step-by-step guide:

  • Open the device settings and go to the “Optimization” menu.
  • Click on the “Battery” icon in the lower left corner.
  • Now tap on the button in the form of three dots in the upper right corner.
  • In the menu that appears, click on “Additional settings”.
  • Flip the Quick Charge switch to the off state.

Wireless technology

than all other communication modules, the 3G / 4G module is prone to heating. In idle mode, it should not consume a lot of energy, which means that the temperature should remain within the permissible range. Overheating troubles can begin during file downloads if you use third or fourth generation networks for this. To avoid them, it is better to connect to Wi-Fi, which, moreover, is more efficient in using battery power.

To make sure that strong heat does not occur through Bluetooth, NFC or GPS, try turning them off for a while in the settings.

Ambient temperature

Much depends on the temperature overboard, that is, the environment. The temperature of any equipment depends on this factor, since it can cause it to overheat even in idle mode. You need to pay attention to external thermo-indicators.

Also, pay attention to whether the phone is in direct sunlight. This is fraught with rapid heating of the device case and possible failure of the internals. The battery suffers the most from this, because it strongly depends on the temperature drop.

Modern models are naturally protected against high or very low temperatures. In any of these cases, they will show the user a warning and turn off when the degree of heat rises or falls within the permissible maximum. To protect your gadget, do not leave it in the heat in direct sunlight and do not give it a heavy load.

We also suggest paying attention to which case you are using. There are materials that conduct heat poorly, which means it stays inside, which prevents the phone from cooling down in time. Perhaps the structure is very closed and the materials are dense. Try to use your gadget without this accessory.

System failure or technical problem causing overheating

Overheating issues can cause operating system crashes as well as preinstalled system apps. Over time, unnecessary files can accumulate there and need to be cleaned from time to time. The built-in “Optimization” functionality allows you to perform the necessary operations, but you should not do it every day.

Another reason could be a technical hardware problem. For example, when Wi-Fi fails, the smartphone can often overheat for no apparent reason, and the user most often sins on unoptimized software, but the problem can hide much deeper. In this case, you cannot do without the hand of a specialist.

If you cannot cope with the excessive heating of the mobile device, then contact the nearest service center. Fortunately, Samsung has opened a huge number of service centers throughout Russia.

The phone is overheating in a running application

You may have noticed that as soon as you start using a particular application, the mobile gadget immediately heats up and after a while you notice that the temperature of the device has risen to an uncomfortable level. This often happens with the official client of a social network. therefore, users often choose analogs such as Lite or Tinfoil.

Keep in mind that YouTube, Acrobat Reader, ChatON, Hangouts, Google Maps, Samsung AllShare, Google Music and Movies, and LINE are also “heavy” programs.

What to do if your Samsung Galaxy smartphone gets very hot

Galaxy, like many other smartphones, can get warm. There are many factors that can provoke overheating of a mobile device, so you should understand the issue very carefully. This may be due to the fault of the user, the fault of the gadget itself, or even third-party factors.

Of course, a device with passive cooling (without a cooler) will warm up and eventually overheat under continuous load. But we will deal with problem cases, the reasons for which we do not know or we are only guessing.

You play games a lot

Not all users understand that prolonged use of a mobile device, especially for games, has a large effect on temperature. The phone does not have time to cool down, that is, it gives off heat and, as a result, it can get very hot.

Experts advise leaving the Galaxy with the screen off for a while so that it can cool down while you continue to use it, whether it’s gaming or work. It is highly discouraged to use it while charging as it may overheat even faster.
