スマホが熱くなる! 原因と対処法を徹底解説

Smartphone overheating is a problem that many users face on a daily basis. The device is prone to overheating, especially when used for long periods of time or with power-hungry apps. This issue can affect the performance and battery life of your smartphone. In this article, we will take a closer look at the main causes of smartphone overheating and effective ways to deal with it.

Why does my smartphone get hot?

Having a hot phone is a common phenomenon experienced by many users, especially after prolonged use or using certain apps. When your phone heats up, it can cause problems like slower performance and shorter battery life. Here we take a closer look at what causes your phone to heat up.

1. High load applications

Intensive applications, such as games and video streaming apps, consume a lot of resources, which causes the CPU and GPU of your phone to work at full capacity, resulting in heat generation.

2. Apps running in the background

Having lots of applications running in the background constantly uses your phone's processing power, which can lead to increased heat and make your phone hot.

3. Too thick a phone case

Thick smartphone cases can prevent the smartphone from dissipating heat, which can lead to heat buildup inside the smartphone and make it overheat.

4. Use in high temperature environments

If the external temperature is high, the smartphone itself will heat up easily. You should avoid using the smartphone in the summer or in places exposed to direct sunlight.

5. Use while charging

If you use your phone while it is charging, the temperature may rise rapidly due to the combination of heat generated by the battery and heat generated during use, which may cause your phone to heat up.

6. Deterioration of old batteries

Smartphone batteries deteriorate with use. Old batteries can become less efficient and generate more heat. Battery deterioration is also one of the reasons why your smartphone gets hot.

Although it is unavoidable for smartphones to heat up, it is possible to minimize heat generation by understanding the above causes and taking appropriate measures. However, if your smartphone continues to heat up even after eliminating these causes, please contact your retailer and request a repair.

The impact of ignoring your phone's heat

When your smartphone gets hot, is it okay to just leave it alone?

The answer is, it's better not to.

Ignoring your phone when it gets hot can have a negative impact on the lifespan and performance of your device. Here are some specific effects:

Slow performance

When your phone gets too hot, the processor inside it will slow down to prevent it from overheating, which can lead to slower apps and reduced overall performance.

Reduced battery life

High temperatures can damage your battery. Prolonged exposure to high temperatures will cause the battery to deteriorate faster, resulting in a shorter battery life.

Hardware Damage

If the smartphone is exposed to extremely high temperatures for a long period of time, the internal components of the smartphone may be damaged. In particular, delicate components such as the display and circuit board are vulnerable to high temperatures and may cause malfunctions.

Data loss

Hardware failure due to overheating can cause data loss. If important data is stored on the device, there is a high risk of losing it.

Increased safety risks

If your phone becomes extremely hot, it also increases the risk of fire or explosion. Overheating, especially while charging, poses serious safety risks, so be careful.

For these reasons, it is important to respond immediately if your smartphone becomes hot. By taking the appropriate measures, you can extend the life of your device and use it safely.

What to do when your smartphone gets hot

If your smartphone is overheating, don't worry. In most cases, there are simple steps you can take to cool it down. Here are some easy-to-follow tips to help you.

What you should never do when your smartphone gets hot
Do not put in the refrigerator

Never put your iPhone in the refrigerator or freezer to cool it down. Sudden changes in temperature can damage the internal components and cause them to malfunction.

Do not cool directly with water

It is extremely dangerous to cool a smartphone directly with water. Even if the smartphone is waterproof, water can get inside, which can cause a short circuit and breakdown.

What to do when your smartphone gets hot
1. Give your phone a break

First, let your phone rest for a bit. If your iPhone is overheating, you may see a warning message like "Your iPhone needs to cool down."

If you see this message, avoid continuing to use your iPhone - simply close all open applications and let your phone sit for a few minutes to allow it to cool down.

2. Avoid high-load applications

If you use applications that put a strain on your smartphone, such as games or video playback, for a long time, it will inevitably heat up. Try to limit the time you use such apps or reduce the frequency of their use.

3. Close background apps

Apps running in the background continue to use your smartphone's resources. Check the background apps in the settings menu and close any unnecessary ones.

Disable unnecessary system services: Go to Settings > Privacy > Location Services > System Services and turn off any options you don't need.

4. Use in a cool place

When it's hot outside, your smartphone can easily heat up, so try to use your smartphone in as cool a place as possible.

5. Avoid using the device while it is charging

If you use your smartphone while it is charging, the battery will heat up easily. Try to avoid using it as much as possible while it is charging and wait until charging is complete.

6. Switch to a lighter, thinner phone case

Thick smartphone cases can prevent heat dissipation. By replacing your phone with a lighter, thinner case, your phone will be able to dissipate heat more efficiently and reduce overheating.

By following these precautions, you can ensure the safety of your smartphone and use it comfortably for a long time. If your smartphone becomes hot, try to stay calm and take appropriate measures to cool it down.
