Common Reasons for Overheating Phones

Too Many Apps Running in the Background

One of the most common reasons why your phone overheats is due to too many apps running simultaneously. Modern smartphones are designed to handle multitasking to a certain extent, and the operating system typically manages resource allocation efficiently. However, if you are running resource-intensive apps or have numerous background processes consuming CPU resources, it can lead to increased heat generation.

The Android Device Factor

The type of Android device you use can also influence whether your phone gets hot. Some Android phones have been reported to heat up faster than others, depending on the phone’s processor. Some processors are designed to be more power-efficient and generate less heat, while others may prioritize performance at the expense of increased heat production. Higher-end phones with flagship processors generally have better thermal management systems and are more capable of handling intensive tasks without overheating.

Malicious Software

Overheating can be a symptom of malicious software on a phone. Malware often runs processes in the background that consume significant CPU resources and initiate excessive network connections. These activities can put a strain on the phone’s processor, causing it to work harder and generate more heat.

Environmental Factors

Exposing your phone to direct sunlight or leaving it on hot surfaces is another reason your phone gets hot. This can cause the phone’s internal temperature to rise beyond its normal temperature. Avoid direct sunlight and hot environments whenever possible.


Adverse Effects of Overheating Phones

The impact of a rising temperature on your phone goes beyond the surface-level sensation of heat. Oftentimes, its effects can be more severe and have long-lasting consequences.

First on the list is the possibility of permanent damage to internal components. Prolonged exposure to high temperatures can cause irreversible harm to sensitive electronic parts like the CPU, GPU, motherboard, and battery. This damage can render your phone inoperable or lead to reduced performance.

Will your phone catch fire when it gets too hot?  Maybe not to that point. Combustion of phones due to overheating is typically associated with manufacturing defects — just like the infamous Samsung Note 7. That being said, it’s important to take action and prevent your device from excessively generating heat.


Android vs. iPhone Overheating

Android and iPhone devices, while known for their impressive capabilities and sleek designs, can occasionally fall victim to overheating issues. When it comes to Android, the sheer diversity of manufacturers and hardware configurations can contribute to varying degrees of overheating. Factors such as resource-intensive apps, background processes, or inadequate cooling systems can all play a role.

On the other hand, iPhones, with their tightly controlled hardware and software integration, are generally less prone to overheating. However, iPhone users may still encounter overheating when pushing their devices to the limits or due to environmental factors. Ultimately, both platforms strive to provide powerful user experiences, but understanding their unique overheating tendencies can help users make informed decisions and ensure optimal device performance.

How to Cool Down an Overheating Phone

1. Activate Airplane Mode

Activating airplane mode can help cool down your phone to some extent. When you enable airplane mode, your phone disables its wireless communication features such as cellular data, Wi-Fi, and Bluetooth. This can reduce the workload on the phone’s radio antennas, which generate heat during normal operation. You can enable your phone to enter Airplane Mode through the little airplane icon found in the notification panel of Android phones or the control center on iPhones.

2. Remove Your Phone from Phone Case

Allow your phone to breathe and remove it from its phone case if you are using one. Phone cases can sometimes trap heat generated by the device, especially if they are made of materials that do not allow for proper heat dissipation. While we’re at it, consider using cooling phone cases that utilize materials that help conduct heat away from the device. The Razer Arctech phone case line, for instance, uses a thermaphene technology that keeps phones safe from overheating issues while also providing shock protection.

3. Use a Cooling Accessory

There are cooling accessories available, such as cooling pads or fans, designed to help dissipate heat from your phone. These accessories can provide additional airflow and cooling to prevent overheating.

4. Turn It Off

If your phone feels excessively hot or is experiencing severe overheating, it’s a good idea to power it off and give it some time to cool down before using it again. When you power off your phone, it stops running processes, reduces power consumption, and allows the device to cool down more quickly.

How to Prevent Phones from Overheating

1. Close Unused  Apps

Make it a habit to exit or force close any unnecessary apps running in the background that may be consuming resources and generating heat. As mentioned. when apps run in the background, they can continue consuming CPU resources and generating heat, even if you’re not actively using them.

Force-closing apps can vary slightly depending on the device model and operating system version. iPhones with TouchID require double-pressing the Home button to view active apps — swiping them up will close them. iPhones without the physical home button simply require swiping up from the bottom of the screen to bring up the app switcher.

Android phones, on the other hand, typically have a Recent Apps or Overview button (usually a square or rectangle icon) at the bottom of the screen. Tapping it will show you the list of recently used apps, which you can swipe to close.

2. Avoid Overcharging

You may be fond of charging your iPhone overnight — although it’s not exactly dangerous, it’s not recommended either because doing so may lead to overcharging and excessive heat generation. The best time to unplug your phone from charging is when the battery hits 80%. Avoid leaving your phone charging after exceeding 100%.

Alternatively, you may enable adaptive charging (Optimized Battery Charging on iPhone) on your phone to avoid overcharging. Many smartphones have this feature, which learns from your charging routine and sleep pattern to delay fully charging past 80% until you need to use the device. You can find it under the battery section of your phone settings.

3. Manage Screen Brightness

Managing screen brightness is a helpful measure to prevent phone overheating. The display is one of the components that can generate significant heat, especially at higher brightness levels — so, it’s a good idea to avoid maximum brightness settings unless necessary.

Many mobile phones nowadays have an auto-brightness feature that allows the device to automatically adjust the screen brightness based on ambient lighting conditions. This is called “True Tone” on iPhone, which you can enable through Settings>Display & Brightness. On the other hand, you can enable auto-brightness on Android under the Display & Brightness settings (location may vary based on phone brand.)

You may also manually adjust the brightness through the slider found on Android’s notification panel or iPhone’s control center.

4. Use Antivirus Software

Antivirus apps play a crucial role in preventing phone overheating by actively monitoring and managing the device’s resources and processes. These software solutions detect and eliminate malicious programs, which can be a common cause of overheating. By scanning for and removing malware, viruses, and other potentially harmful software, antivirus programs help reduce the strain on the device’s CPU and memory, preventing excessive heat generation.

Additionally, antivirus software can identify and terminate resource-intensive background processes or apps that may be running unnoticed, further alleviating the burden on the device’s components. With real-time monitoring and proactive threat detection, these software solutions provide a protective shield, ensuring that the phone operates smoothly and efficiently, while also reducing the risk of overheating-related issues.
