What to do when the Samsung phone heats up and quickly discharges? What is the reason for the abnormal heating of the Android phone?

If your Samsung Galaxy phone gets warm after a few hours of use or while charging, this is normal. However, if it heats up to such an extent that it becomes impossible to hold it, then this is no longer normal. Something needs to be done about this. It is necessary to find out if the problem is the operating system or technical, then the specialist should take a look at the device.

In this post, I will tell you a couple of things that you should do if you notice that your phone is heating up abnormally or even overheating.

This issue should not be underestimated as you may have heard how the Galaxy Note 7 rocked the Android community and kept them on their toes for months following reports of fires caused by the device's faulty battery. So, for the safety of readers, I offer a few practical troubleshooting steps if the phone starts to heat up.

The purpose of this troubleshooting guide is to understand if there is indeed a problem with your phone and to make sure that you, as the owner, are safe. Again, this issue should not be taken lightly, because more often than not, overheating is caused by a battery that may not be working properly.

Mobile phone batteries can explode, and I have personally encountered such a case. As they say, here's what you need to do...

Step 1: unplug the charger and unhook it from the phone

If you are charging your device and notice that it is heating up like never before, stop the charging process. While we don't know if the problem is in the phone, the battery or the charger, but for your safety, stop charging the phone.

After unplugging your phone from the charger, keep monitoring the phone's temperature to know if it continues to heat up even if it's not charging anymore.

Step 2Turn off your phone

If the temperature does not drop after disconnecting the charger, turn off the phone to see if the temperature drops. If it's still hot after a few minutes, then don't do anything to it, just take it back to the store and have a technician look at it.

Step 3: Charge your phone when the power is off

On the other hand, if the temperature dropped after the charger was disconnected, it is possible that it only heats up when it is turned on during charging. Now you can try charging it while it's turned off to see if it can recharge the battery without getting hot.

If a lot of applications are running in the background, the phone may get warm and charging it in this state will also contribute a little to the heat. So, after finding out that the phone charges normally when turned off, move on to the next step.

Step 4: Start the phone app in safe mode and 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 your charger.

Charge your phone for 5 minutes and try to see if it's overheating. If the heating is within limits, then the problem could be caused by some applications that are running in the background. Try to see if you can do something with these applications. 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 you have released the Power key, press and hold the Volume Down key.
Keep holding the volume down key until the device finishes rebooting.
Safe Mode will be displayed in the lower left corner of the screen.
Release the Volume Down key when you see Safe Mode enabled.
Uninstall apps that are causing problems.

Step 5: factory reset your phone

Considering that the phone may still get warm even in safe mode, or if your phone does get warm even if it is not charging, restart it immediately to see if the problem is caused by system conflicts or some features.

However, if possible, back up your files and data and then do a factory reset so you don't lock up your device after a reset.

Why is my Samsung Galaxy battery draining fast?

1. Close all unused applications. This can be done using the Recent Apps button located to the left of the Home button. In the additional features available, optimize the automatic brightness of your device.

2. You can also use the additional battery optimization feature located in the settings. Go to advanced option and select "Optimize battery usage". Here you can choose to optimize selected or all applications. Pay attention to the features that turn off the background and data sync when using this mode.

3. Turn off unwanted features such as Bluetooth or location mode. Check and turn off location tracking - if it is proprietary and the map app is using it, the battery will drain faster, and your phone will constantly search for a GPS signal, which will cause heat.

It's best to have it turned off when you're not using the cards. Many other apps also tend to use location tracking, so it's best to turn it off for better power savings and less heat.

4. Using 4G and 3G data for a longer period - When 3G or 4G data is continuously used by a smartphone, the CPU and GPU work continuously, which causes heat.

5. Too many apps running at the same time - sometimes there are too many apps open on the smartphone, which can lead to heating due to unnecessary processes running in the background.

6. Check regularly for app and software updates. To do this, go to the Play store, find "My Apps" and select update all. To check for operating system updates, go to settings and find the “Phone” tab and then “System Update”.

If all of the above methods could not fix Samsung overheating, then the problem is not with the operating system, but with the components of the smartphone. It is necessary to contact the service center to inspect the malfunctions of the device.

Weak smartphone heating is a common thing for most devices under certain conditions. But if your smartphone is warming 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 causes, consequences and options for eliminating the 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 a morning without visiting the World Wide Web to find out the latest news, see the weather, and just check e-mail.

But what to do if your smartphone or other device becomes very hot? Instead of the usual, pleasant pastime with your gadget, the operation of the device begins to simply annoy. And, as you know, the 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.

Why does the smartphone get hot? Reasons for heating

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

You have a pretty powerful device. If you are a happy owner of an expensive smartphone, then it is likely that it has an advanced “stuffing” installed, which generates a lot of heat under heavy loads. In this case, it is often not the processor that is to blame, which is very hot, but the design miscalculations of the smartphone manufacturer, which did not organize a good cooling system.
Are you an advanced gamer? and the phone has a bunch of gaming novelties installed. No matter how good the smartphone is in terms of gaming, prolonged work with demanding applications leads to heating.
Running applications 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 battery power and avoid strong phone heat.
Heavy loads and long work without interruption. Even the hardware needs to rest a little, non-stop work simply exhausts your device, and it starts to overheat.
Communication problems. In remote places where the network coverage is poor, a special module that is responsible for communication begins to work more intensively, heating up along the way.
Software issues. The phone can warm up due to the “clumsy” firmware, which was created by a non-professional. The reason for the heating may be the official update of the system (this happens very rarely, but it is possible).
Smartphone hardware malfunctions. Various kinds of problems with the hardware of a smartphone or tablet (processor, memory modules, etc.) often cause overheating, but they can only be detected at a service center. Without special skills, poking around in the "insides" of the device is not worth it.
Poor ventilation. While in a bag or a tight pocket, a smartphone, on which various tasks are performed in the background, may well heat up. Here, the processor also heats up, which has nowhere to remove heat in a closed space, and heat also comes 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 the smartphone to become very hot. The tips are simple: try to dry it using a plate of rice, or better yet, send the device to specialists 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 heat build-up as heat dissipation is slower. But if you are used to protective cases, 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 will warm up, if it should, then slightly 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. Here you should not postpone - 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 a few tips to help you beat the heat:

CPU overheating. This problem is pretty 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 work. It is advisable to periodically clean up 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 should be noted, are themselves prone to strong heat - nothing can be done about it.
Heating associated with the mobile network. The constant search for a network, which is often done by a smartphone, causes a small, but still heating of the smartphone. As a rule, the module responsible for finding the network gets 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, prioritize the network (2G, 3G, 4G) that has the best coverage at your location so that your smartphone does not constantly switch between them.
Long screen on. The display can also get warm sometimes, for example when you are playing games or watching a movie. Just give your gadget a little rest. If the heating is strong, it is necessary to visit the service center.
With unfinished or incorrectly updated software, which causes heating, the output is a rollback to previous versions. It is advisable to use only trusted download sources or official firmware and updates.
Overheating caused by direct sunlight, constantly staying in a pocket or a tight case, next to heating appliances. 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 games.
Overheating caused by improper charging. Remember, when you charge your phone, you need to use only a high-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 restarting 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 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 established by the manufacturer of your gadget, the violation of which sometimes leads to overheating. Here are the standard rules and regulations established by almost all phone manufacturers, which it is desirable 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;
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 right, 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 manufacture of your phone or other device.

Conclusion

In order to solve any problem, you need to unambiguously determine the cause of its occurrence. So it is with the heating of the device. To understand what is behind the overheating of the phone, for starters, just take it in your hand and try to understand which part is heating 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!

This question was asked by every owner of a smartphone. It becomes more relevant when the heating becomes very strong, so much so that the gadget is simply uncomfortable to hold in your hands. Let's see why the phone heats up, and whether this is a normal phenomenon at all.

Heating is normal

How does the CPU work in general? It passes a current through the semiconductors with a huge frequency, resulting in a strong heating of the crystal (processor shell). Therefore, any phone cannot but heat up during operation. Technologies in which the processing of a large amount of data would occur without heat generation have not yet been invented. Therefore, if your phone is heating up, then this is quite normal. This phenomenon is explained by the use of modern hardware, which is able to calculate large amounts of data.

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

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

CPU

The processor is the "heart" of any smartphone, since it is he who processes the entire amount of information and passes the data stream through him. The chip in a desktop computer or laptop, for example, has a small size, but at the same time a large heatsink (aluminum plate with fins) is installed on it, and a fan is installed on the heatsink. This cooling system is necessary in order to remove heat, which is sure to be released during the operation of the CPU. There, the problem of heat removal is easier to solve because of the larger space inside the case. However, in compact and thin phones, it is not possible to install a large radiator or fan to remove heat, so you should not be surprised why the phone heats up.

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

When to start worrying?

There is nothing to worry about if the phone gets warm after 15-20 minutes of playing - this is completely normal. The temperature may rise even when watching high-definition videos or surfing the Internet. Of course, it is desirable to give the phone a little rest and cool down, but there is nothing wrong with the fact of heating.

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

Software

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

Display

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

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

Battery

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

Phones usually get warm when charging. If a powerful charger with a current of 2A is used or the smartphone processor supports Quick Charge technology, then the heating will be more intense. There is no need to worry too much here. But if the phone in the locked mode (without charging) heats up or does not cool down for a long time, then there is clearly a problem. In this case, it is desirable to take it in for repair.

Non-original battery

Also, the cause of the heating may be a non-original battery. If the "native" battery no longer holds a charge, then buying a cheap non-original analogue is not the best solution. It may well be ineffective or even unsafe. Do not be surprised at the heating of a smartphone with non-original spare parts.

Conclusion

Some Android smartphone users are facing the problem of excessive heating of their devices. You can’t let it go by itself, so you need to figure out why the Samsung phone is heating up as soon as possible and try to fix this problem.

Causes of phone heating

During operation, absolutely all smartphones have a temperature increase. This is due to the heating of the processor, battery and display. But it's one thing when the device just gets a little warm, and quite another when it gets so hot that it's not comfortable to hold it in your hand.

It is with excessive overheating that Samsung Galaxy owners often encounter, which is due to the powerful filling of the smartphone. In general, the main reasons can be divided into the following:

high processor load with tasks;
heavy games and applications;
battery failure.

Important! If the battery (not to be confused with processor heating!!!) becomes very hot during charging, this is not fatal, but when this happens even in normal operation, and even more so if it quickly discharges at the same time, urgently take the device to a service center!

How to protect your phone from overheating

The easiest and most effective way is not to use heavy applications. It is also recommended to switch between communication options to a minimum, using one all the time, for example, 3G.

The most difficult to implement, but also the most effective method is to lower the processor frequency. This not only reduces the heating temperature of the smartphone, but also increases the battery life.

To lower the frequency of the processor, you need to get a little confused. To do this, you need Root rights on the phone, a custom kernel, or firmware like CyanogenMod. Then it remains to install the SetCPU application and adjust the processor frequency through it. If you are interested in this process, then you can easily find detailed instructions on the Internet. Just keep in mind that any interference with the regular operation of iron is fraught with breakdowns and loss of warranty. As they say, everything is at your own peril and risk.
