The phone often overheats, what should I do? The phone gets very hot when locked or charging, this is normal

Low heating of the smartphone is common for most devices under certain conditions. But if your smartphone gets so hot that it is impossible to hold it in your hand, then you urgently need to sound the alarm - the device is probably malfunctioning. The causes, consequences and options for eliminating excessive 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 no longer possible for many to imagine the morning without visiting the World Wide Web to find out the latest news, check the weather, and just check email.

But what to do if your smartphone or other device starts to get very hot? Instead of spending the usual, pleasant time with your gadget, the operation of the device begins to simply irritate. And, as you know, morning largely determines the mood you will have throughout the day. What is the reason for the phone heating up? Where is the problem? Let's try to figure this out in order to return the correct operation of the gadget and the good mood of the user.

Why does my smartphone get hot? Reasons for heating

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

• You have quite a powerful device. If you are the happy owner of an expensive smartphone, then it is likely that it contains advanced hardware that generates a lot of heat under heavy loads. In this case, it is often not the processor specifically that is to blame, which gets very hot, but the design mistakes of the smartphone manufacturer, who did not organize a good cooling system.
• Are you an advanced gamer? and a bunch of new gaming products are installed on the phone. No matter how good a smartphone is in terms of gaming, long-term work with demanding applications leads to heating.
• Applications running in the background. Often, smartphone users do not turn off background functions 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 battery power and avoid the phone from overheating.
• Heavy loads and long work without breaks. Even the hardware needs to rest a little; working without breaks simply exhausts your device, and it begins to overheat.
• Communication problems. In remote places where network coverage is weak, a special module that is responsible for communication begins to work more intensely, heating up at the same time.
• Software problems. The phone may get warm due to clumsy firmware that was created by a non-professional. The reason for the heating may also be an official system update. (this happens very rarely, but it is possible).
• Smartphone hardware malfunctions. Various types 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. Without special skills, there is no point in tinkering with the “insides” of the device.
• Poor ventilation. When placed in a bag or tight pocket, a smartphone on which various tasks are performed in the background may well become warm. Here the processor heats up, which in a closed space has nowhere to remove heat, and heat also emanates from your body.
• Contact with water or other liquid. If you are used to listening to music on your smartphone while in the bathroom or simply accidentally poured water on it, it will most likely simply fail. However, moisture can cause the smartphone to become very hot. The advice is simple: try to dry it using a plate of rice, or better yet, send the device to a specialist for treatment.
• Case. A smartphone in a case, and even under load in hot weather, is the same as playing sports in a fur coat. Most cases that are made of dense materials lead to heating, since heat dissipation occurs more slowly. But if you are used to protective covers, then try to find a solution made of thin material, with ventilation holes.
• Bad battery. Often it is the battery that is the source of high temperatures. Naturally, a serviceable battery should warm up only slightly 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. There is no need to delay here - replace the battery yourself or contact a service center.

When you have been able to identify the reasons for the strong heating of your smartphone, you can try to fix the problem yourself. Here are some tips to help combat extreme heat:

• CPU overheating. This problem is quite easy to solve. We remove or disable unnecessary applications and processes so that they do not hang in the background. In principle, the operation of several processes will not bring any harm to the smartphone (that’s why it is a smartphone), but the abundance of useless background tasks will naturally affect its operation. It is advisable to periodically clean out background processes and remove unnecessary applications. Often, to cool the processor, it is enough to leave the phone alone for a while. A number of chipset models, it is worth noting, are themselves prone to strong heating - there’s nothing you can do about it.
• Heating associated with the mobile network. Constantly searching for a network, which a smartphone often does, causes the smartphone to heat up, albeit slightly. As a rule, the module responsible for searching for the network gets especially hot in remote places, where it has to work several times more intensely. If it is possible to use Wi-Fi, then it is better to use this interface. When this is not possible, set priority to the network (2G, 3G, 4G) that has the best coverage at your location so that your smartphone does not constantly switch between them.
• Screen on for a long time. The display can also sometimes become warm, for example, when you play games or watch a movie. Just give your gadget a little rest. If the heating is strong, you need to visit a service center.
• In case of unfinished or incorrectly updated software, which causes heating, the solution is to roll back 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 pocket or a thick case, next to heating devices. Everything here is simple: 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 on it.
• Overheating caused by improper charging. Remember, when charging your phone, you should only use a high-quality charger. It is advisable not to load your 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 latest licensed updates were installed. If the smartphone continues to heat up after restarting, then restore the device to factory settings, saving important information before doing so. If this does not solve the problem, contact the service center.

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

• do not talk for more than 30 minutes at a time;
• constant use of powerful applications;
• constant viewing of videos in HD quality;
• You should 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 do 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 service center professionals. Most likely, the cause of overheating is errors in the production of your phone or other device.

Conclusion

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

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

In this article we will try to find out what can be a source of heating in the body of your device, what means an increase in the body temperature in one place or another, and also how to deal with the noted problem.

A little theory

It is no secret to us that a working device undergoes many processes that are hidden from the human eye. This includes the work of the same processor, power consumption, graphics processing, and much more. 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 gets hot. To understand the true reason, it is necessary to find out which of the device modules is heating up, after which we will understand the reason for this phenomenon. And to know what gets hot, you need to understand where the heating occurs. This is easy to find out: pay attention to the place where the temperature rises.

In total, there are not many elements in a smartphone that can heat up. These are: battery, processor and display. Only these parts can cause a serious increase in temperature during their operation. Because of them, the phone heats up, but the reasons for this are different. Read more about this in the following sections, divided by the criterion of which element becomes hot.

Powerful processor

We buy devices that have 4-8 cores, capable of running any application and processing any task in a matter of milliseconds. And this gives certain positive results: working with a powerful phone is much more pleasant, because it is much less buggy and at the same time supports the operation of colorful games and applications without any problems. Therefore, we try 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 calculation processes, it will heat up in any case. Only, unlike a laptop, the insides of a smartphone cannot be cooled. There is no miniature cooler-fan driving air around the “heart”. That’s why the phone you work with for at least half an hour or an hour gets warm.

The degree to which the device heats up also depends on how “cumbersome” the tasks assigned to it are in terms of performance. If you play a colorful 3D game at maximum settings for 2 hours, the phone will heat up more than when simply surfing the Internet.

Battery

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

Therefore, if you have been using your phone for a long time, the battery may become warm, causing 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, due to the fact that the back cover of the device is only slightly warmer than our body, there is no need to worry. Very soon it will cool down and return to its previous mode.

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 from the device? If this is your first time your phone gets very hot, we recommend turning it off as it may damage it even more. After this, you need to understand what the reason was: perhaps you used a non-original charger; or the battery has been replaced. There are quite a lot of factors influencing this, including the need to understand how quickly the phone heats up, how long it takes to cool down, what applications were open at the moment when you felt the temperature rise.

Taking all this into account, certain conclusions need to be drawn.

Hot display

Perhaps, if you notice that your mobile device screen is heating up, you shouldn’t worry about it. Most likely, you simply spent too much time on your gadget, which is why the temperature of some of its components began to rise. For this reason, for example, a Samsung phone often gets hot.

The degree of heating depends on the type of display used and the brightness setting. If the temperature rise issue bothers you too much, you can try turning down the brightness; if this does not help, contact the service center. They should tell you whether this is a normal temperature for your device or not.

Charging process

It often happens that the phone gets warm while charging. There is nothing surprising about this - when connected to the network, the charging adapter begins to heat up, after which the temperature of your smartphone’s battery also increases. If, again, you can hold your device in your hands without getting burned by it, there is no need to panic. Otherwise, we advise you to take the phone for repair and it is advisable to refuse to use the charger, so as not to cause further damage. It happens that the phone heats up when charging if the network adapter fails. If this happens in your situation, be careful: it may harm your gadget.

Communication problems

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

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

Do no harm!

If you feel your device heating up for any reason, first of all try to protect yourself from unpleasant situations, such as further breakdown and failure of the phone. Unplug it, turn it off, disconnect the battery - all these actions are aimed at rebooting the gadget, letting it cool down and start working normally. Only if these actions did not help get rid of the problem, start to figure out what’s wrong.

Individual working mode

Also remember that all devices are different in some way (in terms of temperature standards). One smartphone can operate at one temperature, while for another it is considered unacceptable, and vice versa. Don't be alarmed if you bought a gadget and noticed that it gets hot. Read reviews about this: you may not be the only one who has encountered this problem.

A modern smartphone is a device that simplifies life and helps a person in everyday activities. The phone, like other equipment, contains heating elements. Often, under heavy load, their temperature rises, which leads to heating of the phone body. The most common source of elevated temperature is:

• CPU;
• Battery;
• Display.

Heating at least one of the elements leads to an increase in the temperature of the entire smartphone as a whole. This problem can occur in any phone, even a completely new one. But if a recently purchased smartphone heats up noticeably during normal use, then you should contact the office of the company where the purchase was made to obtain a replacement or warranty service. However, there are also natural reasons for a smartphone to heat up.

CPU load

This problem may occur when using applications that load the processor. For example, running processor-heavy games or using several applications at once.

Solution:

The problem can be solved in this case simply: you need to disable heavy processes and use one or several (simple) applications at the same time. If there is a need for simultaneous use, then this will not cause any harm to the smartphone. But with regular and prolonged use, problems may begin.

Using 3G or 4G networks

When using these networks, the phone's transmitter has to transmit a signal many kilometers to the nearest 3G base station (or 4GBS). Therefore, the further away the BS, the more power the phone needs to transmit the signal. This reason also includes the use of a Bluetooth connection, but most often it does not bring the smartphone to critical temperatures.

Solution:

The solution is to take short breaks to allow your smartphone to work. The phone cools down quickly, so 4-5 minutes will be enough. Another solution is to use an alternative network, namely Wi-Fi. In this case, the phone's transmitter does not have to transmit the signal over long distances, so the smartphone will not heat up.

Prolonged display use

The problem most often occurs when watching movies or videos for a long time. It is easy to diagnose - the front of the phone is noticeably hotter than the back.

Solution:

While watching a movie, turn off (leave your phone in a locked state) for a couple of minutes, and as soon as you feel that the display is cold again, you can continue watching.

Long conversations

The explanation for this problem can be given the same as in paragraph 2. This reason rarely manifests itself, but still in some phone models that are especially susceptible to heat, this can cause a battery malfunction, which will be described below.

Battery fault

The last and probably worst reason for a smartphone to heat up is a faulty battery. It is the worst because it is followed by a whole series of problems. At a minimum, it warms up the phone. This problem is easy to identify yourself. If the smartphone case is opened, open it and carefully touch the battery.

It should be a little warm, but if it is hot, then you should think about replacing the battery. The appearance of the battery may also be a cause for concern. When it malfunctions, it begins to swell. The battery takes on a “swollen” shape on one side, with dents on its surface. Using such a battery is dangerous: such a malfunction can cause the smartphone to explode.

Solution:

The solution is to replace the battery. All phone batteries are designed to last a certain number of times, so don't be surprised if battery problems start to appear after years of use. It is worth noting that when replacing the battery, do not skimp on the original part. After all, using non-original or unsuitable accessories for your smartphone can lead not only to repeated problems with the battery, but also to breakdown of the phone in general.

Consequences of prolonged heating of the phone

All components of the smartphone can easily withstand increased temperatures. But it is still better not to subject the phone to prolonged loads with subsequent heating. The consequences are most often associated with a battery malfunction, namely: rapid discharge, disconnection of a charged battery.

The phone gets very hot - a fairly common problem for devices based on Android OS. If your Android smartphone gets very hot, then you need to do something about it, since high temperatures can lead to failure of one of the vital components of the smartphone. Now let’s figure out why the phone gets hot and how you can deal with it.

So, first of all, the phone’s battery and processor heat up. In turn, high battery temperature can lead to an explosion! Therefore, it is better to avoid overheating. Unfortunately, smartphone manufacturers have not yet come up with an ideal heat sink, but we can help without the latest developments and replacement of components.

Why does my Android phone get hot? Background applications!

Of course, it is very difficult to cause your smartphone to seriously overheat with just background applications, but if you have a bunch of applications running and at the same time you decide to play a “heavy” game, it will overheat.

Background applications will waste processor and battery resources even if you have a lot of RAM and the interface runs very smoothly. So, if your phone gets very hot, close unnecessary background applications! For these purposes there are built-in " task managers", opening either by clicking on " Recent Applications", or by holding down the button " Home" Simply swipe away unnecessary apps.

The phone gets very hot when playing games

If you play “light” games, then this problem will bypass you, but in the case of “heavy” games shooters, racing And other genres, which uses the latest graphics and physics, the smartphone is doomed to overheat.

If your phone battery gets hot while playing games, just take breaks. This is the simplest and yet most effective solution. You, of course, can make the graphics not so beautiful, or even lower the maximum processor frequency, but this way you can lose a good experience from the game, because it will be “dull” and simply look bad.

Disable unused connections

It's no secret that GPS, Wi-Fi, mobile Internet and Bluetooth connections can consume a lot of energy. And as we have already found out, the phone’s battery and processor heat up. In this case, the battery will be actively consumed, which will lead to an increase in the temperature of the battery and other components of the phone.

If you want your phone to hold a charge longer and get less hot, turn it off:

• GPS (Google Maps and other apps can check your location "without asking" at any time to provide you with the right clues)
• Mobile data (Wi-Fi is more energy efficient, so if you need Internet access constantly, it is better to use Wi-Fi)
• Bluetooth (in sleep mode it does not consume much energy, but it’s still better to turn it off)

Charge correctly!

During charging, the phone battery of many people heats up, this is not surprising, since now almost all Android devices have fast charging, which greatly “strains” the battery at the time of charging. To ease his difficult fate, follow the recommendations:

• Charge only with a compatible charger and cord. Ideally, you need to use the factory charger that came with the device, but if it breaks, select a new charger according to the factory parameters
• Do not use the phone while charging. Seriously, leave him alone for another hour, let him rest.
• Do not cover the phone while charging.

Monitor the brightness level

Why does my phone get hot? – Because the brightness is at maximum level! Use automatic brightness control. If your smartphone does not do this or you do not like the brightness levels it sets, reduce the brightness during active use, for example, playing games or watching high-definition videos over the Internet.

Use the right case

A good case is an investment in the longevity of your device. But what qualities should a good case have? First of all, the case should protect the device from damage, not complicate use and not contribute to overheating.

At first glance, it may seem that a leather case is a great choice, but unfortunately, leather cases have an unpleasant side effect. The fact is that the skin does not help cool the back panel of the smartphone, but on the contrary, the heat is retained and the smartphone simply “cooks”. If your phone gets very hot, it is better to remove the case.

In terms of cooling, the ideal solution is a bumper that will cover only the side edges, but in this case the main purpose of the cover will be “lame” - protection.

Install antivirus

If your phone gets very hot and none of the above tips helped you, then most likely your smartphone has a “worm” that is actively leaking your data to third parties. Install antivirus, scan your smartphone and remove malicious applications.

These simple tips will help your smartphone serve you faithfully longer.

We are becoming more and more dependent on our smartphones as they become the go-to device that we use for everything that is so important these days. This is not bad, but when you depend so much on your smartphone, you need to start taking serious responsibility for it so as not to lose important data. But when your Android smartphone starts to heat up, it can cause a real problem for both you and your smartphone.

One of the main questions we ask ourselves when we notice a sudden spike in the temperature of our phone is “what is causing our phone to overheat and can it be fixed.”

Why does my Android phone get hot?

Overheating of Android phones is a normal situation in its own way. On average, almost all Android devices tend to overheat during heavy CPU and GPU usage. If you use Android hardware resources heavily with heavy applications, your smartphone will overheat.

The main types of overheating are:

1. CPU overheating
2. Battery overheating

CPU overheating

This is the most common type of overheating for every Android phone and tablet. This type of overheating is not a problem and you can control your device to generate less heat by monitoring your use of apps installed on your smartphone.

1. Uninstall unnecessary apps: The more apps you have installed, the more heat your phone will produce. Just uninstall unnecessary apps that you do not use because these apps are always running in the background and increase the heat generated by the CPU and GPU during heavy use.
2. Clean cache and junk files: Use any clean master app to clear junk and cache files from your Android phone or tablet frequently. If the cache fills up all the time, the CPU will have to work harder to process the data, resulting in unnecessary heat.
3. Use 4G/LTE/3G networks: If you are using 3G or 4G networks on your device, make sure the network reception is good. Because low network signals mean Android devices' processors and radios will work harder, causing the battery to run faster and become hotter. So, use 3G/4G/LTE only in the zone if it's good, or use Wi-Fi whenever possible as it consumes less battery in comparison.

Smartphone battery overheating

The battery may overheat when using 3G/4G and Wi-Fi networks. However, if your battery is always hot, this could be a serious problem. A constantly hot battery means it is damaged. A normal battery will not heat up while charging, but a faulty battery will.

If your battery is faulty, you should only replace it with a battery from the manufacturer! Faulty batteries can explode at any time and completely damage your Android device.

The life cycle of a typical smartphone battery ranges from 300 to 500 charge cycles. You don't need to count how many times you charge your smartphone, but if you charge the battery once a day, you should change the battery every 1-2 years.

Overheating due to software update

This problem is rare, but has been seen on Android phones and tablets during software updates. Recent issues with Samsung's Galaxy Note 4, AT&T Galaxy Note Edge and Galaxy Note 3 among others have seen users complaining that their phones started overheating without any heavy use. Both AT&T and Verizon have released subsequent OTA updates to fix the overheating issues.

If this is the case, then you can either wait for a new update to arrive, or you can downgrade your Android phone to prevent overheating.

Tips for Cooling Android Devices

• Avoid excessive phone use
• Playing on a smartphone for a long time can cause overheating problem
• Do not charge your phone while using the device
• Try removing the phone case you use to protect your phone, as it prevents your device from cooling when in direct contact with outside air.
• Monitor your phone's battery behavior. To do this you can use an app like Battery Repair Life
• Some apps and games have a negative impact on your smartphone's processor and battery as they not only eat up your phone's hardware resources but also continue to consume them even when you are not using them. You must find the culprit apps and remove them.
• In addition, you also need to monitor the applications and processes running in the background. You can find some useful tips to stop background applications on our resource.
• Keeping and using WiFi and Bluetooth for a very long time can also heat up your Android smartphone. So you should avoid it

I have never used an app that claims to cool the CPU and battery temperature on Android devices. But numerous reviews from users of such applications indicate that they really work. You can try phone cooling apps to see if they really work for you.
