Why does my smartphone get hot?
Phones getting hot is a common issue experienced by many users, especially after extended use or certain apps. When your phone gets too hot, it can cause issues like slower performance and reduced battery life. Here, we'll take a closer look at what causes your phone to get hot.
1. High-load application usage
Intensive applications like games and video streaming apps consume a lot of resources, which can cause your phone's CPU and GPU to work at full capacity, resulting in heat generation.
2. App operation in the background
Having lots of applications running in the background constantly uses your phone's processing power, which can increase heat generation and cause your phone to get hot.
3. Too thick a phone case

Thick phone cases can prevent your phone from radiating heat, which can trap heat inside the phone and cause it to overheat.
4. Use in high temperature environments
If the external temperature is high, the smartphone itself will heat up easily. You should avoid using it in the summer or in direct sunlight.
5. Use while charging
If you use your phone while it is charging, the battery heats up and the phone heats up while in use, which can cause the phone to heat up.
6. Deterioration of old batteries
Smartphone batteries deteriorate with use. Older batteries can become less efficient and generate more heat. Battery deterioration is also a factor in smartphones getting hot.
While overheating of smartphones is an unavoidable phenomenon, it is possible to minimize overheating by understanding the causes listed above and taking appropriate measures. However, if your smartphone continues to overheat even after eliminating these causes, please contact your retailer and request a repair.

The consequences of ignoring your phone's heat
Is it okay to leave my smartphone alone when it gets hot?
The answer is, it's better not to.
Ignoring your phone's heat can have a negative impact on the device's lifespan and performance. Here are some specific effects:
Performance degradation
When your phone gets too hot, the processor inside it will slow down to prevent overheating, which can cause apps to run slower and reduce overall performance.
Reduced battery life
High temperatures can damage your battery. Prolonged exposure to high temperatures will accelerate battery degradation and result in a shorter battery life.
Hardware damage
If the smartphone is left in an extremely high temperature condition for a long time, the internal components of the smartphone may be damaged. In particular, delicate components such as the display and circuit board are susceptible to high temperatures and may cause malfunctions.
Data loss
Hardware failure due to overheating can result in data loss, and if important data is stored on the device, the risk of losing it increases.
Increased safety risks
If your phone gets 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 take immediate action when your smartphone becomes hot. By taking the appropriate measures rather than leaving it unattended, 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.

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 temperature changes can damage internal components and cause malfunctions.
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 malfunction.
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 might see a warning message like "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 rest 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 amount of time you use these 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 get hot, so try to use it in a cool place.
5. Avoid using the device while charging
If you use your smartphone while it is charging, the battery will heat up easily. Try to avoid using it while charging and wait until the charging is complete.
6. Switch to a lighter, thinner phone case
Thick smartphone cases can hinder heat dissipation. By replacing your phone with a lighter, thinner case, your phone will be able to dissipate heat more efficiently, reducing overheating.
By following these precautions, you can ensure the safety of your smartphone and ensure its long-term use. If your smartphone becomes hot, try to stay calm and take appropriate measures to cool it down.
