Why does a mobile device get hot?

Smartphones can fulfill more functions every day. This means more use of your processor and RAM , which forces your devices to work much harder.

For this reason, it is normal for mobile devices to get hot when we use several applications at the same time. The new phones are designed to be able to handle and meet these kinds of demands and, at some point, it is normal for them to get hot.

However, if the overheating is excessive or sudden , to the point that the phone becomes very slow and even shuts down there is a problem with the equipment, so you should consider taking a look.

It is normal for the mobile to get hot when using YouTube, Waze or when playing some games of Call of Duty, but if you are not doing with it and when you pick it up you feel hot for no reason, something is definitely happening that is affecting your battery.

In this article we will explain the main reasons why a mobile device overheats to the point of shutting down and what can be done in these cases to solve the problem.

Why does a mobile device get hot?

All mobiles tend to get hot at some point, but there are certain factors that cause the device to increase its temperature much more. Among the main causes of heating of a mobile we have:

Multiple apps running in the background

The most common is that one or more applications are abusing the use of resources in the background. This means that even if the applications are not open, they will be running.

If we add to this that many applications are running at the same time, it will imply a greater effort for the mobile, resulting in an increase in its temperature.

To solve this problem, you must go to settings and force the stop of all applications that are running in the background.

Phones with a tendency to heat up

There are mobile companies that do not incorporate heat sinks in their equipment, others that do have but do not disperse the heat well enough or simply the execution of multiple processes generate more overheating in some mobiles than in others.

The fact is that there are certain computers that tend to overheat more than others, but generally the most popular models tend to be better worked in that sense and therefore, the overheating of these is much lower.

Why does my phone turn off when it overheats?

There are several possible reasons why your phone shuts down when overheating, however the most common is an overcharged battery . The lithium ions contained in the battery are overstimulated and this generates an overheating in the mobile.

When this part of the battery fails, the device shuts down. Similarly, some mobiles can turn off automatically when they exceed a certain temperature as a safety measure so as not to affect the internal components of the equipment.

Likewise, there is also the possibility that your device has overheating problems due to its processor. Some phones with processor Snapdragon 810 suffered much this problem progressive overheating.

Recommendations to avoid overheating in the phone

One of the best recommendations is not to install applications that promise to cool down your mobile. Although it seems a contradiction, these types of applications do not fulfill the function they offer.

On the contrary, they overload the phone with an application that will be constantly running in the background, will fill the mobile with advertising and possibly infect it with malware, making your device much hotter than usual.

Another good recommendation is not to overload your phone   . You must always be aware of your device, since once it is charged to 100% it will begin to overheat due to excess energy. This decreases the life of your battery.


Continuing with the previous premise, avoid using fast charging more than necessary. This type of charge overheats the mobile very quickly, so if you are not careful, it can reach a very high temperature.

This type of action will cause your mobile to overheat and if this is frequent, it may start to turn off suddenly , so we recommend avoiding this type of action.
