Cell phone overheating: understand why and how to avoid it

When you have an electronic device, it is essential to know about common problems that can happen and one of them is overheating. An overheating cell phone , for example, could indicate this malfunction for several reasons.

Prolonged use in heavy applications, bugs in the operating system, defective battery and some defective internal component are some factors that cause this overheating. But before you despair and throw “ cell phone overheating what to do ” or “my phone is overheating” search tools, continue reading.

In this guide, we will help you with the question: “why is my cell phone heating up?” and give tips on what to do and how to prevent the problem.

Why is the cell phone overheating?

Basically, there are three parts of the device that heat up the most: the battery, the screen and the processor. All of them are directly connected with the electric current that runs through the conductors for a certain period of time. Thus, the more the processing power, the more energy consumption and heat will be generated.

In this way, if you are watching a movie on your cell phone with the screen at its maximum brightness, it is a fact that it will trigger overheating. Another example is if you are playing a heavy game for many hours without breaks. And one more fact is that a cell phone charging is a cell phone overheating, since, at that moment, the device is receiving direct energy from another source, however, this is not always synonymous with a problem, especially when your charger is of the turbo type, or i.e. it loads faster.

There are several other factors that contribute to an overheating cell phone. We have listed some of them below. Check out:

● When there are several applications open and running in the background;

● When there is a bug in the operating system;

● When a bug occurs in any running app;

● Long phone calls;

● Applications that are too heavy for the device’s processor or GPU;

● Restoration with backup;

● Wallpapers that are 3D animations;

● Defective battery;

● Cell phone infected by virus;

● Leave Bluetooth and Wi-Fi on when not in use;

● Run very heavy games for a long period of time;

● Recording videos at very high resolutions or streaming video for a long period of time;

● Screen brightness is always at maximum;

● The cell phone cover does not have adequate ventilation outlets for the device;

● The charger is faulty or an unreliable brand.

As we have already mentioned here, overheating can come from several reasons, but one of the main culprits is usually exposure to high temperatures, such as using the cell phone under a very strong sun on a summer day or leaving it in a car. closed.

What to do in these cases?

A tip to check if the device is really heating up more than it should is to download applications like Cooling Master and CPU-Z.

If you notice overheating, follow these steps:

  • Turn off your cell phone and unplug it if it is charging;
  • Remove the protective cover or case, if any;
  • Keep the device in a cool and airy place, away from the sun or any kind of strong light until it cools down.

Another tip is to avoid placing the smartphone on tables or counter tops made of cold stone, if the back of the electronic device is made of glass, as this could end up causing a thermal shock and causing cracks in the device.

How to prevent overheating?

After understanding a lot about an overheating cell phone, how about preventing this problem? See our guide:

1. Remove the protective cover

Covers are necessary, in most cases, to protect the device from impacts and scratches, but they can also serve as a greenhouse, obstructing the cell’s heat output. If your smartphone is overheating, remove the cover and place it in an airy place.

Do this, mainly, when charging the device, since the electric current will certainly increase the temperature of the battery. When cool, put the cover back on.

2. Close and/or delete apps

The harder the processor is working, the more it needs power and therefore generates heat.

The best way to resolve this situation is to simply close applications that are not in use. Some of them, like antiviruses, are running in the background and thus always require some CPU work as well.

If that doesn’t solve it, you can also stop it working or delete those apps that no longer open. It’s always good to clean your cell phone to ensure that it can perform its functions without making a big and unnecessary effort.

3. Avoid high temperatures

Lithium-ion batteries are very sensitive to heat and end up suffering when the temperature exceeds 30ºC. In most of Pak, it is naturally complicated to keep the device below that level, but even so, it is recommended to try to alleviate the situation.

Therefore, never leave your cell phone in direct sunlight, especially in closed and stuffy places, such as the inside of a car. Also, do not leave the device near a stove, barbecue or any type of heat source.

Whenever you are in a very hot place, the first recommendation is to remove the protective cover. Don’t forget that an overheated cell phone can even explode, although this is a very rare situation.

4. Check the charger

Faulty chargers can trigger an overheating phone. This happens because poorly welded or bare wires can fail when receiving the passage of electric current, presenting a risk of even short circuits.

Another tip is to always opt for the original product, even if the cost is higher. Always buy models according to the correct specifications of your smartphone and check whether or not the device supports a turbo charger.

Also, it is important to pay attention to another issue: wireless chargers also tend to heat up the cell phone, so if you are using a wireless base and the device is very hot, switch to a wired charger.
