It’s quite common to feel your phone getting hot to the touch, especially during extended use or when charging. Best temperature for optimal performance of a mobile phone is from 0℃ to 35℃. However, it becomes unsafe if it exceeds 45℃.

While a warm phone may not seem like a big deal, it’s important to understand why it happens and how to prevent it, as prolonged overheating can lead to damage to the battery and other components. Furthermore, it reduces the overall lifespan of your phone. There are many reasons why a mobile phone might get hot, some of which are normal and others could be a cause for consideration.

In this article we will discuss why mobile phones get hot and how to prevent them.

Phone Heats Up During Charging

One of the most common reasons why mobile phones get hot is due to charging. While charging, the battery generates heat and if you continue to use your phone during that time, it can cause it to heat up even more. It is especially true when using a fast charger or charger is not compatible with a phone. I have mostly found that overcharging is the main reason behind the heating of the mobile phone’s battery.

You can prevent the phone overheating using the original charger that comes with the phone box, as it is specially designed to work with your device. Also avoid using the phone while charging and don’t leave it plugged in for extra time once it is fully charged.

Using The Phone For Long Periods Causes Overheating

Another common cause of overheating in mobile phones is using them for a long time continuously especially for power intensive applications like games or streaming HD quality videos. When you operate it for a long time, the processor and other components generate heat, which can cause the phone to become hot.

When it is necessary to use it continuously for hours, you should take frequent breaks and avoid using heavy applications for such a long time. Additionally I would suggest reducing the screen brightness and turning off unnecessary features like WiFi, Bluetooth, GPS etc., when not in use.

Heavy Processing Results In Phone Overheating

The processor is one of the most important components of a mobile phone. It is responsible for performing all the tasks and running the apps on your device. When overloaded with too many tasks or apps, the processor has to work harder, generating more heat. Moreover, it can also become hot when using heavy apps like games and tasks like HD quality videos. Same problem persists for live streaming in case of unstable WiFi signals.

You should close any apps you are not using and avoid running too many tasks simultaneously to resolve the issue. Additionally, I have a practice of clearing the cache regularly and keeping the phone’s operating system updated. It has helped me resolve the overheating issues and keep the performance of my phone up to the mark.

Phone Overheating In Direct Sunlight

Exposure to direct sunlight can cause your mobile phone to heat up quickly, especially if you are using it simultaneously. When exposed to direct sunlight, the temperature inside the device can rise rapidly, causing it to become hot to the touch.
Therefore you can protect your phone from overheating by not using it in sunlight for prolonged time. Additionally, the experts recommend keeping your phone in a cool place when not in use and using a protective case that provides some insulation from heat.

Older Battery Can Cause The Phone To Overheat

Another common cause of overheating in mobile phones is battery issues. If your phone has an old or damaged battery, it may not hold a charge as well as it used to, which can cause it to generate more heat than usual. Additionally, if your phone’s battery is swollen, it can put pressure on other components in the phone, which can cause it to overheat.

It is a safe practice to replace your phone’s battery every two years or when required according to its health. Moreover, if you notice any swelling or damage to the battery, you should immediately stop. Otherwise it can result in fire aggravating the damage to irrevocable level.

Poor Ventilation Causes Your Phone To Overheat

Mobile phones are designed with internal components that generate heat. If you don’t make arrangements to properly dissipate it, it can cause them to overheat. One common reason for poor ventilation is using a phone case that does not allow proper airflow around the mobile phone.

You can avoid using phone cases that cover the phone’s ventilation holes or block the airflow to keep it cool. You can also remove these cases while playing games or charging your phones. Moreover it is a preventive measure to avoid using your phone in a tight space or with a sealed cover over the device.

Phone Overheating Due To Malware Or Virus

Malware or virus infections can cause your phone’s processor to work harder than usual, generating more heat. Moreover, they can also cause your phone to run programs or processes in the background, which can consume more battery power and become hot. You should be conscious if it overheats on standby mode.

You can prevent the issue by installing a reputable antivirus program on your device and avoid downloading apps or files from untrusted sources.

Phone Overheating Due To Obsolete Software

Software issues can also cause your phone to overheat. For example, if an app is poorly coded or has a bug, it may cause your phone’s processor to do more computations resulting in its overloading. Furthermore, if your phone’s operating system has become obsolete, it can create issues like a lack of optimum processor performance and other auxiliary components. Therefore, it will consume more power than usual and can overheat.

You can keep your phone’s operating system and apps updated to ensure its best performance without any heating issues. For this purpose, application developers and manufacturers issue patches and regular updates to resolve any bugs and improve the performance of the systems. Furthermore, you should avoid using beta versions of apps or operating systems, as they may contain bugs that can cause your phone to overheat.

Phone Gets Hot Due To High Ambient Temperatures

Normal temperature for internal parts of a mobile phone should be below 45℃. High ambient temperatures can cause it to increase beyond this range because of poor heat dissipation. When the temperature around your phone is high, the temperature inside the phone can rise quickly, which can cause it to become hot to the touch.

You can easily avoid it by not using your phone in environments with high temperatures, like industrial areas. Moreover you can keep it in a cool place to maintain its temperature within acceptable limits.

Conclusion

Overheating is a common problem that many mobile phone users face. However by understanding the common reasons for overheating and taking precautions to prevent it, you can keep your phone functioning properly and prolong its lifespan. Whether you’re using your phone for personal or professional reasons, it’s important to take care of it and ensure it stays cool for its smooth functioning.
