How to keep your smartphone cool during a heat wave

As the world grapples with unprecedented heat waves, it's not just humans and animals that are feeling the heat; our gadgets are suffering too. Smartphones, which have become our constant companions, are particularly vulnerable to overheating. Hence, it's essential to understand how to keep your smartphone cool in such sweltering conditions. In this guide by Axios, we delve into some effective tips that will help you safeguard your device against overheating.

Understanding the Perils of Overheating

Overheating can cause several issues in smartphones. It can slow down performance, drain the battery faster, and even lead to physical damage to the hardware. More importantly, in extreme cases, overheating can cause the phone to shut down abruptly to prevent permanent damage.

Avoid Direct Sunlight

One of the most straightforward strategies is to keep your smartphone out of direct sunlight. Leaving your phone in direct sunlight, especially inside a car, can rapidly increase its temperature. Always place your phone in the shade or within a bag to keep it cool.

Reduce Screen Brightness

High screen brightness can generate additional heat. Reduce the brightness level of your screen when not necessary. Using auto-brightness can also help as it adjusts the screen brightness according to the surrounding light conditions.

Close Unused Apps

Running multiple applications in the background can strain your phone's processor and generate heat. Ensure you close apps that you are not actively using to reduce this burden on your processor.

Turn Off Unnecessary Features

Features like Bluetooth, GPS, and Wi-Fi consume a lot of power and can contribute to your phone heating up. Turn off these features when they are not required to help keep your phone's temperature down.

Avoid High-Performance Games

Playing high-performance games or using heavy applications can lead to an increase in temperature as the CPU and GPU of your smartphone work harder. Limiting your use of such apps during a heat wave can help in maintaining an optimal temperature.

Use Airplane Mode

Airplane mode can be a quick way to cool down your device as it turns off all wireless communications. If you don't need your phone for a while, switch it to Airplane mode.

Remove the Case

While phone cases offer protection, they can trap heat. During a heat wave, it might be beneficial to remove your phone case to allow heat to dissipate more easily.

Keep the Phone Ventilated

Ensuring that there is adequate ventilation around your phone can help. Avoid placing it on soft surfaces like beds or couches where it can easily overheat. Instead, place it on a hard surface where air can circulate around it.

Limit Camera Usage

Using the camera, especially for recording high-quality videos, can cause your phone to heat up. Try to limit the usage of your phone's camera in extreme heat conditions.

Charge Smartly

Charging your phone generates heat. Avoid charging it in direct sunlight or in places where the temperature is high. Also, don't cover your phone while it's charging to allow heat to escape.

Use Power Saving Mode

Using the power-saving mode can help reduce your phone's temperature. This mode typically limits the phone's performance and restricts background activities, leading to less heat generation.

Apps to Monitor Temperature

There are numerous applications available that can help you monitor your phone's temperature. These apps can alert you when your phone is getting too hot, allowing you to take necessary steps to cool it down.

Temporary Switch Off

If your phone is overheating and none of the above measures are helping, consider switching it off for some time. A short break can help in cooling down the device completely.

Avoid Extended Calls

Engaging in long phone calls can also cause the device to heat up. Use hands-free options or make shorter calls during a heat wave.

Battery Care

Batteries are integral to the heating issue. Avoid using your phone while it is charging and use reputable battery-saving apps. Additionally, replacing an old battery can help if overheating is a consistent problem.

Use Cooling Accessories

Some accessories, like phone cooling pads and fans, are specifically designed to dissipate heat. These can be particularly useful when you know you'll be using your phone extensively.

Avoid Heavy Graphics

Try to limit the usage of apps that use heavy graphics as they put additional load on the processor and contribute to overheating. Browser-based versions of apps can sometimes be a viable, lighter alternative.

Stay Updated

Keeping your apps and operating system updated can also help, as manufacturers frequently release updates to optimize performance and fix overheating issues.

Regular Maintenance

Regularly check and clean your phone's ports and speakers. Dust and debris can also trap heat and restrict cooling efficiency.

Heatproof Your Environment

Lastly, try to stay in cooler environments yourself. If you are comfortable, it is likely your phone will be too. Create an environment that keeps both you and your gadgets safe from the excessive heat.

By implementing these tips from Axios, you can ensure the longevity and optimal performance of your smartphone even during the most brutal heat waves. Stay cool and keep your devices cooler!
