How to keep your phone cool in hot weather

Heat affects your phone's processor, the chip responsible for its main functions.


Do you often find your phone struggling to perform in the heat? Unlike humans, phones can’t sweat, which means they can overheat and slow down. In this guide, we’ll explore why electronics struggle in the heat and provide you with practical tips to keep your phone cool and functioning optimally.

Step 1: Understanding the Heat Challenge 

Heat affects your phone’s processor, the chip responsible for its main functions. The internal processes generate heat while working, causing the processor to slow down to prevent overheating. Additionally, the battery works harder and drains faster in high temperatures.

Step 2: Avoid Direct Sunlight 

Direct sunlight is a significant source of heat for your phone. To keep it cool, avoid exposing it to direct sunlight as much as possible. Keep it in the shade or indoors when not in use, and refrain from leaving it in your car.

Step 3: Charging Precautions 

Charging your phone generates heat, which can exacerbate the temperature issue. Avoid charging it when it’s already hot. Instead, charge it in a cooler environment or wait until it cools down before plugging it in.

Step 4: Optimal Positioning 

Smart placement plays a crucial role in maintaining a cool temperature for your phone. Position it away from heat sources, such as vents or radiators. If possible, place it in front of a fan to promote airflow and dissipate heat.

Step 5: Lighten the Load 

Reduce the workload on your phone by turning off unnecessary functions and features. If you’re not using GPS or other power-consuming apps, disable them to minimize energy usage and heat generation. Additionally, consider removing the phone case to allow for better heat dissipation.

Step 6: Utilize Low Power Mode 

Many phones offer a low-power mode that restricts background processes and optimizes power usage. Enable this mode when your phone is struggling in hot weather to conserve energy and reduce heat generation.

Step 7: Cooling Breaks 

If you notice your phone overheating or experiencing performance issues, give it a break. Turn it off for a few minutes to let it cool down before using it again. This break helps prevent further damage and allows the phone to recover from excessive heat.

Step 8: Avoid Drastic Temperature Changes 

While it may be tempting to cool down your phone quickly, avoid extreme temperature changes. Never place your phone in a fridge or freezer, as rapid cooling can lead to condensation and potentially damage the internal components. Instead, stick to natural cooling methods like air circulation.


By following these simple steps, you can protect your phone from overheating and maintain its optimal performance, even in hot weather. Keep your phone out of direct sunlight, charge it smartly, reduce its workload, and provide it with occasional cooling breaks. With these precautions, you can enjoy a cool and efficient phone throughout the summer and beyond.
