Samsung phone gets warm when charging
The battery is swollen
The reason the battery swells up is that the smartphone has been lying on something warm for a long time. Only repair and replacement of a swollen battery with a new one will help here.
Smartphone heats up while charging
The general rule for all smartphones is not to touch it while it is charging. Manufacturers say that the batteries in their phones can withstand any load, including charging and working at the same time, but experts advise against doing this.
If your smartphone gets warm, unplug it while charging. Only use a cable from an official manufacturer. a Chinese charger can also heat up the device. If the phone stops working after overheating, you need to carry it to the service. The same must be done if the charger from the manufacturer also starts to warm up.
reasons why the phone is warming up
It is normal for the smartphone to get warm from intensive use. It’s bad when it starts to overheat. Constant overheating will wear out the battery faster, shorten the lifespan of the phone, and decrease performance.
There are five main reasons your smartphone overheats, and in this article, we’ll show you how to avoid them.
Extra items are stored in the case
It is convenient to carry a bank card or electronic pass in a smartphone case. they will not get lost, you will not forget them at home, but it’s better not to do that. The cards will demagnetize over time, and the phone will constantly heat up. Therefore, remove all unnecessary items from the case.
The cover retains heat
Manufacturers put plastic transparent covers on their devices. These covers can be used the first time after purchase, but it is better to change the solid plastic over time for a more ergonomic option. A plastic case with no ventilation holes traps the heat of the smartphone, causing it to overheat.
Smartphone overheated in the sun
In such a situation, turn off the device and leave it in a cool place. The batteries of most phone models are designed for such loads, so a cooled smartphone can be used as usual.
Basic principles to remember: the smartphone should not be left in the sun or a hot surface, and its access to air should not be blocked.

Overheating of 3G / 4G modules
3G / 4G modules provoke phone overheating more than others. Most of these problems occur during an active connection, when downloading files or processing large amounts of data.
It is normal for the temperature to rise steadily while the wireless module is operating, but if the readings are critical, it is recommended to take the phone for repair.
Samsung phone overheats while charging
It is normal for the phone to heat up slightly while charging. The main thing is to ensure the release of thermal energy into the external environment, therefore, when charging, do not cover the smartphone with a cloth or other object.
Several years ago, a number of reports of mobile battery explosions circulated on the network while the smartphone was being charged. Most often, such situations arise not due to overheating of the device, but due to a problem with the battery itself or the charging unit. A short circuit and fire gives rise to a voltage surge, not a rise in temperature. Therefore, it is safe to leave the phone on charge longer than the prescribed time.
This is especially important during the wireless charging process. Phones equipped with this option have a built-in cooling system.
If overheating is significant, turn off the fast charging function in the smartphone settings and try to charge the device in the usual way, using a wire.
The main ways to avoid overheating your smartphone
Based on the reasons listed above, the following ways to prevent overheating can be distinguished:
- Check and close unused apps periodically.
- When installing applications, take into account the characteristics of your device and choose the utilities that are optimal for them.
- Watch the charging mode, always provide conditions for heat dissipation.
In some Android versions, you can see the temperature of the case in a special section. It is located in the settings items called “Battery”. In the future, the developers preferred to put more effort into optimizing the increase in degrees than on the visual design of this information, and abolished this paragraph.
Overheating of the smartphone due to applications
Each app has minimum and recommended phone requirements. The minimum requirements allow you to use the program, but on the minimum settings and with the condition of the minimum load of RAM and processor by other applications. If, after installing and launching the program, you notice a rapid rise in temperature, it may be too heavy for your smartphone. Change the settings in it to lower ones or look for a less resource-intensive analogue.
Many applications are used in the background
Too many programs running in standby mode can lead not only to overheating, but also to the deterioration of the phone as a whole. Open Task Manager regularly and close unnecessary programs. Thus, you will save the load on the processor, RAM consumption and battery power.
Why Samsung phone is overheating and what to do about it?
Many users wonder why Samsung Galaxy overheats quickly and what to do about it? Fast and strong heating of the device can scare us and force us to carry the phone to the service. However, this symptom may not always indicate the presence of serious problems. We will analyze the known causes of such a problem and how to fix it.
Why does my Samsung phone get warm??
There are two important parts under the cover of the smartphone: the battery and the processor. The body can heat up due to excessive load on these parts at the same time or separately. Most often, an increase in temperature indicates an increased load on the device, malfunctions in the operation of the processor, its individual components, and overheating of the battery. Heating within the temperature range specified in the instructions is not dangerous and is provided by the manufacturer. Temperature rise above these limits can be dangerous for the device itself and the user. Let’s take a closer look at each of the situations.
Many running applications
The heat generated by a smartphone is also affected by the number of programs open in the background: they all consume hardware power, as a result of which many running ones cause an increased load. Such software is unloaded from memory over time (this is one of the principles of the Android OS), but most should still be closed on your own. the easiest way is to swipe up, opening the list of recent applications.
Applications load the device
The main scenario in which you can notice overheating is the use of demanding software: official clients of social networks (primarily), three-dimensional games with good graphics (for example, Fortnite), some instant messengers (in particular, Whatsapp) and almost all popular applications for dating. Also, almost any program can fall into the category of demanding, if the developers did not bother to check and optimize it.
This reason is not easy to deal with on your own. The best method is to find an alternative to the “gluttonous” software: the same has both an official lightweight client and third-party options. You can also just wait: perhaps only this particular version of the program is problematic, and with the next update, the high resource consumption will be eliminated.
Heating while charging
An attentive user may notice that during the charging process, his Samsung heats up, sometimes quite noticeably. This can also be considered the norm, since when charging a lithium-ion battery, heat is generated, especially if the phone claims support for Quick Charge technology. If the temperature seems too high for you, use the following recommendations:
- Do not charge your phone on surfaces that interfere with heat dissipation, such as a bed, armchair, or similar furniture.
- Do not leave the phone charging in rooms where temperatures are high or near heat sources such as radiators.
- If you still have power supplies from previous devices, you can use them: the charging speed, of course, will drop, but the heat generated will also decrease.
- You can also disable fast charging in the gadget settings. open the corresponding application and use the item “Device maintenance”.
At the bottom of the list there should be an option “Other battery settings”, click on it.
Tap the “Quick Charge” switch.
Your Samsung will now charge at normal power, which again will slow down the speed but lower the temperature.
For users who prefer to charge the device wirelessly, we recommend spending money on the appropriate official accessory, rather than using cheap options. The fact is that with this type of battery charging, the phones heats up even more than with the usual wired method, as is known to Samsung, which has provided cooling means in wireless charging stations.
The procedure for charging gadgets should be taken seriously and do not neglect the above tips.
Increased ambient temperature
If high rates of heat emitted by the device are observed in a hot room or outdoors in summer, then there is nothing strange in this: the increased temperature of the environment also affects the speed and quality of cooling the phone. Here are some helpful tips:
- In the summer, minimize the use of the gadget in direct sunlight, and even more so do not leave it charging on the car panel under the windshield.
- Pay attention to the case, if used. Samples that cover the device from all sides (tourist “armored” cases, book covers) also sometimes significantly affect the cooling, and with constantly increased indicators, it makes sense to think about using a thinner accessory.
- If the device signals too high a temperature, to accelerate cooling, it can be turned off and left in this state for up to 15 minutes. a complete shutdown will take all the load off the hardware components, allowing them to cool down faster.
- At the time of this writing (April 2021), external coolers for smartphones are increasingly appearing on the market. manufacturers position them as gaming accessories.
The benefits of such funds (regardless of the price) are small. with their help it will be possible to reduce the temperature by only 1-2 degrees, which is not enough for active cooling, therefore we do not recommend using them.
In most cases, these recommendations are sufficient to solve the problem.
Heating up while charging. what to do?
If you charge your smartphone wirelessly, the S8 shouldn’t get too hot. Charging with a wired device somewhat affects the temperature rise of the gadget, but cannot pose a threat to it.
The device will be especially hot when you use it while charging. play games, run “resource-intensive” applications. In general, this is also normal. But it’s better not to overuse such things.
How the weather affects the S8 temperature?
If you carry your smartphone in your on hot summer days, you shouldn’t be surprised that its temperature has risen. This happens with absolutely any object, including mobile devices. There is only one way to fight the heat. move the gadget away from direct sunlight. to a place where the environment cannot reach the Galaxy S8. Does the heat threaten my smartphone? If you do not leave it in the hot sun all day, then it is unlikely.
Why the compactness of the S8 affects the heating of the smartphone?
Samsung’s goal is to make a smartphone not only powerful, but also stylish. Therefore, the corporation uses a glass case in its production. and quite thin. Accordingly, if a device performs a lot of tasks, then a slight overheating will certainly be characteristic of it.
If the gadget has slightly warmed up, then you should not sound the alarm. this is just a design feature and there is no way to get away from it.
Weak mobile network signal
You’ve probably noticed that your smartphone’s battery drains faster when traveling. And with a bad signal from the operator, a continuous search for the network can occur and, as a result, noticeable heating and a rapid discharge of the battery. Smartphones can even reboot in certain places, while in other places they behave completely normal.
The number of simultaneously running applications, lack of memory. The maximum load is created by:
- Modern games.
- Watching videos (especially in high quality).
- Video recording on the built-in phone camera (especially in 4K).
- GPS Applications.
- Long and intense data transmission via Wi-Fi or Bluetooth.
- Surfing sites. Yes, sites are now “fat”. with large images, sound, animation and all kinds of widgets. If you scroll through several of these in different tabs, it also loads the processor and fills the RAM.
The bottom line is that under the maximum load, any device will heat up. And if the heating is not accompanied by reboots and freezes, there is no need to panic. Just try not to interfere with the normal ventilation of the device and set feasible tasks for it (read the last paragraph “How to prevent overheating”).
If the temperature is such that the device cannot be held in hand, you need to contact the manufacturer’s support.
run the phone app in safe mode and put it on charge
Now let’s try to check if Samsung can still charge without getting hot when all third-party apps are temporarily disabled. Start your phone in safe mode this time and then plug in the charger.
Charge your phone for 5 minutes and try to check if it overheats. If the heat is within limits, then the problem could be caused by some applications running in the background. Try to check if you can do something with these apps. You may already have an understanding of which of your applications are causing the problem.
How to boot your phone in safe mode:
- Turn off the device.
- Press and hold the power button.
- When Samsung appears on the screen, release the power button.
- Immediately after releasing the power key, press and hold the volume down key.
- Keep holding the Volume Down key until the device finishes restarting.
- Safe Mode will be displayed in the lower left corner of the screen.
- Release the Volume Down key when you see Safe Mode is on.
- Remove apps that are causing problems.
Why Samsung smartphones get hot
Mobile devices are in a fever if we demand a lot from them. You’ve probably noticed this. Running demanding games or other apps, virtual reality or even long video recording is a huge endeavor for Samsung smartphones.
Integrated circuits perform a number of operations that are inconceivable to the “common” person, and they emit heat.
If we add Bluetooth, geolocation, WI-FI and other modules to it, then in some cases we can create a home heat generator. It is also known that the more traffic, the more heat and more power.
So be sure to assess exactly what is heating up. It doesn’t have to be a smartphone processor or even the battery mentioned above.
Fortunately, smartphones are smart. At the IC design level, adequate precautions are taken to keep us out of trouble (not counting the hot case).
However, smartphone manufacturers also want to take care of us by blocking certain functions of the device in case of high temperatures.
Is it harmful to get too hot for a Samsung phone?
We do not like scalding ourselves and this is no different from devices. We can divide into two situations that can occur due to high temperature.
They again depend on the cause of the overheating. In the case of hot electronics, safety remains.
Manufacturers must program all systems and sensors correctly so that components do not exceed a certain limit.
If they approach it, the system receives information to degrade performance, but this in turn refers to design problems.
Samsung smartphones just hate being hot. I won’t go into the chemical details, it’s just that batteries suffer a lot, which, in turn, leads to their reduced lifespan.
Many have probably seen on YouTube that a bad battery is a bomb, so really pay attention to if your Samsung is getting too hot.
The real reasons why Samsung Galaxy phone gets warm
You may have noticed that your Android Samsung Galaxy s3, s7, c4, a8, c8, a3, a5 2017, s7, j5, s8, g1 mini, a7 2018 and so on is clearly overheating.
A smartphone, just like our body, does not like high temperatures. They mean wasted energy, and that’s the price of performance.
A little heat is an intrinsic effect of the processor, but if your Samsung gets too hot, you should definitely consider where it came from.
One of the reasons why the phone heats up is already known is simply the operation of systems inside the device that generate heat.
By the way, the more complex the tasks, the higher the temperature rises. Although most ICs in smartphones and tablets are designed to emit as little heat as possible, an appropriate cooling design is required.
We haven’t seen fans in phones yet, let alone water installations and nitrogen, but different heatsinks are already the norm. If the manufacturer has not taken care of the heat dissipation properly, we will immediately clearly notice this.
The second reason for the high temperature is the battery itself. Chemical changes occurring in the battery can also lead to additional heat.
The most common reasons are: too many applications running in the background, long-term movie streaming, suboptimal phone settings, leaving the phone in the sun, problems with applications or the operating system, and malware.
The consequences can also be different: it gets very hot and quickly discharges, it heats up and turns off or does not turn on. This can happen both while charging and during operation.
How to prevent your Samsung phone from getting hot
There are not many solutions. It all comes down to avoiding a situation where the mobile device starts to heat up.
Yes, it can be hard. It is true that you can turn off the already mentioned modules for determining the location, Bluetooth and others, but playing demanding games, over time, you will feel the warmth in your hands.
For now, we have to rely on the solutions used by the manufacturers. Copper pipes working as radiators are the most efficient solution today. This is best seen in the case of the Samsung Galaxy S7 (Edge), which practically does not get warm, but this solution is not ideal.
The cause can also be infected with malware. The problem occurs when the phone heats up to such an extent that it cannot be held in the palm of your hand or it starts to behave strangely.
First of all, these types of problems can be the result of faulty hardware, but they can also be caused by software defects. In a phone, heat is generated by three main elements: the battery, the processor and the screen.
When the phone gets warm, we usually check the battery first, especially if there is heat on the back of the phone. Modern lithium-ion batteries are extremely spacious and therefore sometimes get hot.
Heating causes the battery to dispose of organic solvents, which can ignite due to sparks or excessively high temperatures. Malfunctioning batteries were the cause of the notorious explosions of Samsung Galaxy phones.
Only if you feel warm in the front of the screen could the processor or graphics chip be the culprit. Both of these elements generate heat during operation, so the more the processor is loaded, the more the temperature rises.
However, if you feel warmth on the bottom of the phone, the battery is the most likely problem.
What to do when your Samsung phone gets very hot
In the case of hot electronics, we need to look for software problems. It is possible that one of the applications running in the background caused the smartphone’s processor to go to high speed.
Such calculations should be eliminated. Also disable unused modules (NFC, Bluetooth, WI-FI, GPS, etc.).
Increased productivity, new communication modules, and thinner smartphones mean an increased appetite.
Why My Smartphone Overheats and How to Stop It
Many theories claim that computing power doubles every two years in a row, so we are talking about huge development, although we are slowly approaching the limit in relation to the applied workflow.
How to tell if your Samsung phone is getting hot
We already know that electronics or batteries can cause high temperatures. How to find out which element is doing it?
Of course, in a place that starts to heat up. Each smartphone is built differently, but almost all popular models on the Internet have been disassembled, so it is not difficult to find out what the inside of a particular model looks like. However, as a general rule, one can distinguish:
- around the main camera. electronics
- bottom, longitudinal part of the back cover. battery
When can we talk about overheating
It is worth remembering that all phones get hot. The normal operating temperature of all phones is 37 to 43 ° C.
Since we don’t have thermometers in our fingers (yet), you need to feel by touch when to stop watching YouTube videos and give your phone a break.
You can also try apps like AIDA64 and Cooling Master, which allow you to control the temperature of your phone.
AIDA64 provides all the information you need about the phone, and Cooling Master is used specifically to detect overheating in phones and fix this problem by disabling applications that cause excessive load.
Another interesting tool is CPU-Z, an application designed to detect CPU overheating. Success.
Why Samsung Galaxy a50 gets warm when using and charging
If your Samsung a50 gets very hot during operation (this is normal when charging), then this is the company’s fault. Why?
Because you are far from alone faced with such a flaw. At first I thought it was the firmware, but it turned out that the Samsung a50 is heating up all over the world. Here is one of the posts in the English forum.
- Only a week has passed since the purchase of the Samsung Galaxy A50, and it has problems. the battery gets very hot and discharges quickly it gets hot during normal use, and extremely hot during games. I sweat playing games because it and it runs out very soon too it runs out of power without using it I want you to understand that I am a very caring person with my phones, so I always close data, other functions and applications when they are not being used I do not have a third-party phone cleaner application. I don’t play games too much, but these problems arise When I play, it starts to heat up immediately after opening pubg and continues to heat up until the end of the game. i can’t use it in direct sunlight for photography or doing other things, it gets very hot in sunlight and when there is a heating problem, there is a battery drain problem Since you have to be consumer oriented i expect to hear me and solve the problem in the next update. I am a Samsung user in the past, my previous phone was Samsung Galaxy j5, so I bought this device instead of redmi note7 pro just because of its good gaming performance, but now my opinion has changed, so if you want your customers to trust you please resolve these problems and, this is not a one person problem, this is a many people problem I hope you fix this soon
Even here on my site there are messages from visitors that their new Samsung a50 is getting pretty hot, and they urge others not to repeat their mistakes and not buy this phone. Here is the last.
- I am facing the same problem too. Even with normal internet use such as surfing, the top and front and back of the camera become abnormally warm. Sometimes even during a conversation. If I kept it in my. I could feel the warmth. The battery also runs out quickly with moderate use.
Yes, there is a problem and it is not known whether the company will solve it. I do not give any solutions in this post.
However, if we proceed from the title of the entry “Why Samsung a50 heats up”, then it corresponds to the name.
If you know something about this problem, you know how to solve it, you have ideas share in the Комментарии и мнения владельцев.
I will give recommendations on how to deal with this in the next entry, but now I say goodbye. Good luck!
This is the first thing that comes to mind when they say that the phone gets very hot. When charging, it is not surprising that the phone’s battery heats up, this is the normal behavior of the battery when energy starts to flow into it. If the temperature of the case does not reach extreme values and the device can be held in hand, you should not raise the alarm. But when the hand cannot tolerate heating, in this case it is worth looking for the problem and solving it. First, make sure that you are using the original charger, in the next chapter we will analyze in detail how to act when the battery in the phone is very hot.
Why the battery is overheating, we have disassembled a little higher, now we need to understand how to properly cool the phone without damaging it. There are several main ways, we will list them:
- Turn off the device, after 30 minutes you get an absolutely cold smartphone, you can turn it on and actively use it.
- Put the gadget in the freezer, after wrapping it in a cloth or stuffing it into a plastic container. After 10 minutes, the body of the device will become cold.
- Place the device under a working air conditioner, the whole issue is resolved.
Reducing the load on the battery while constantly searching for a network
To do this, it is enough to switch the device to power saving mode or the so-called “air mode”. Requests to the cellular repeater will not pass, since the wireless interfaces will be disabled, but you can use the phone, excluding the Internet and voice communication. This will allow you to save battery power until you find yourself in an area of reliable signal reception, then turn off power saving modes and use your smartphone as usual.
A modern smartphone, be it iPhone, Samsung, HTC, is a real computer, the processor of which consists of several cores that process information in a split second. It is not surprising that in the process of operation several processor cores can generate a decent amount of heat. There is nowhere to take it away, mobile devices do not have cooling systems, like in PCs or laptops, so they have to take it to the case. Hence, strong heating of the case may occur.
If you play a dynamic 3D shooter for an hour, you will notice how the phone heats up. The battery will start to sag noticeably, giving energy to the processor for the calculation of the complex graphics of the game. A similar picture can be observed with prolonged surfing on the Internet, the reasons will be similar.
The reasons that the iPhone 5s heats up, we will analyze the most basic of them, perhaps you will immediately understand what is the reason for the breakdown of your device. The instruction is applicable not only to Apple technology, but also to Android devices, since the components are similar in functionality, and sometimes even manufactured at the same factory.
Active use of the cellular network
By analogy with heating with a heavy load on the processor, the device can warm up when constantly searching for a network or actively surfing the Internet. But there may be a situation, the phone heats up and sits down at the most inopportune moment due to poor signal reception. The device tries to maintain a stable connection with the cellular repeater, actively exchanging information with it, so it is not surprising that the batteries in such conditions will last for a couple of hours.
Let’s figure out another situation. why does the phone heat up (iPhone or Samsung, it doesn’t matter) when using 3G or during a long conversation. The situations are similar, the exchange of information is very active, it is because of this that the battery lands, just charged to 100%.
Users know that even in a locked state, a lot of calculations, graphics processing, communication with cellular network repeaters and a bunch of other obscure procedures take place in a smartphone. These processes are an integral part of the system’s operation, but there are software and hardware failures, then the device heats up and quickly discharges for no apparent reason. Let’s analyze the main symptoms by which you can understand that something is wrong with the gadget.
- The body of an iPhone or Samsung is hot, and you can clearly feel it.
- The system is buggy, for example, artifacts on the screen or applications start and minimize themselves.
- There is a general system inhibition, slow reactions to pressing, or their complete ignorance.
- The smartphone battery lasts for 2-3 hours after 100% charging.
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 an 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.
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 to 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 the gadget without this accessory.
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 on 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.
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.
Samsung Phones Warm While Charging | Prevention
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.
We also suggest reading tips for charging your smartphone, as well as answers to questions that probably bother you.
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.
