It happens that the mobile device that we deal with every day starts 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 another thing is if the phone heats up during its inactivity or, say, when performing some simple operations. In this case, you need to understand what is happening and what is the reason.
In this article, we will try to find out what can be a source of heat in the body of your device, which means an increase in the temperature of the case in one place or another, as well as how to deal with the noted problem.
A bit of theory
It is not a secret for us that in a working device there are many processes that are hidden from the human eye. This is the work of the same processor, and the consumption of electricity, and graphics processing, and many other things. If outwardly the smartphone looks calm, then inside it is a series of operations that can cause, among other things, heating.
There can be several answers to the question of why the phone is heating up. 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 is getting hot, you need to understand where the heating occurs. It's easy to find out: pay attention to the place where the temperature rises.
In total, there are not many elements in a smartphone device 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 is heated, only 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 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 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 hardware of the phone is involved incalculation processes, it will heat up anyway. Only, unlike a laptop, the insides of a smartphone cannot be cooled. There is no miniature cooler-fan here, chasing air around the “heart”. Therefore, the phone with which you work for at least half an hour or an hour is heated.
The degree of heating of the device also depends on how "cumbersome" in terms of performance are the tasks assigned to it. If you play a colorful 3D game at maximum settings for 2 hours, the phone will heat up more than just 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 a power outlet or a PC. Therefore, the electricity required for the operation of the processor comes from here. And, as we know, a working electrical appliance can get hot if you connect it to a power source.
Consequently, if you have been working with your phone for a long time, the battery may become warm, which will cause 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, you should not 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 something needs to be done. First of all, you need to know if this has happened before. If not, then whatcaused such a reaction of the device? If this is the first time your phone gets very hot, we recommend that you turn it off, as it can be damaged even more. After that, you need to understand what the reason was: maybe you used a non-original charger; or the battery has been replaced. There are quite a few factors that affect this, including how quickly the phone heats up, how long it takes to cool down, what applications were opened at the moment when you felt the temperature rise.
With all this in mind, some conclusions need to be drawn.
Heating display
Perhaps, if you notice that your mobile device screen is heating up, you should not worry about it. Most likely, you just 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, the Samsung phone often heats up.
The degree of heating depends on what type of display is used and what brightness is set on it. If the problem with the temperature rise is too annoying for you, you can try to reduce the brightness; if this does not help, contact the service center. They should tell you if this temperature is normal for your device or not.
Charging process
It often happens that the phone heats up while charging. There is nothing surprising in this - being connected to the network, the charging adapter starts to heat up, after which the temperature of your battery also rises.smartphone. If, again, you can hold your device in your hands and don't get burned by it, don't panic. Otherwise, we advise you to take the phone in for repair and it is advisable to refuse to use the charger so as not to harm even more. It happens that the phone heats up when charging in the event that the network adapter fails. If this happens in your situation, be careful: it can harm the gadget.
Communication problems
As practice shows, there are a number of situations. when the phone heats up, it discharges and shows unstable operation in general. In particular, we are talking about communication problems.
You see, if the smartphone does not receive the proper signal strength, it tries to find it, connect to the network and work normally. If this fails for a long time, the device consumes its battery power and in parallel starts to heat up. In this case, we recommend switching it to “Airplane Mode”.
Do no harm
If you feel a strong heating of your device for any reason, the first thing to do is 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 normal temperature conditions). One smartphone can work with one temperature, while for another it is considered unacceptable, and vice versa. Do not be alarmed if you bought a gadget and noticed that it is heating up. Read reviews about it: you may not be the only one with this problem.
