Keeping technology devices in good condition goes beyond security measures to protect against computer attacks. And this goes beyond the importance of preventing drops and impacts that can damage screens and internal components. Did you know that they can also be affected by high temperatures? At the beginning of summer days we share a series Tips for protecting your phone from heat.
Hypertext spoke to experts to find out what the harmful effects of heat are on mobile phones. In addition, experts help us analyze good and bad practices that need to be taken into account to maintain the integrity of the equipment. Except, Does external temperature really affect smartphones?
Although we will focus on a number of aspects related to how to protect your mobile phone from heat, the truth is that the following tips are valid for other products as well. For example, laptops, tablets and smartwatches, to name a few. Andres Burshtyn, associate dean and director of the Department of Information Systems at the National Technological University of Buenos Aires in Argentina, emphasizes that the key element is the battery. “High temperatures are very harmful to mobile phones as they cause damage to components and circuits.. In particular, lithium batteries, which are now the most common and are particularly sensitive to heat,” he comments.
Keep your mobile phone away from the heat: “Climate is an important factor to consider”
“There are different reasons why high temperatures are bad for mobile phones,” he says. Hypertext Franco Armentano, IM Product Manager at Samsung Electronics.
We know how important it is to protect your mobile phone from the heat. What are the consequences if this does not happen?
First of all, cell phone batteries are sensitive to high temperatures. A significant increase may cause it to worsen more quickly. On the other hand, cell phone screens can become less sensitive when exposed to extreme heat, which can lead to temporary or permanent failure.
Do internal components also suffer?
Also. For example, processor, RAM and other circuits. This may result in poor performance or even malfunctions. Therefore, it is very important that equipment manufacturing takes this axis into account and makes efforts not only to detect failures and how to subsequently eliminate them, but also to ensure their prevention. Keep in mind that excessive heat can shorten the overall lifespan of your phone by accelerating wear on various components and affecting the structural integrity of the device.
Is there a recommended temperature range when storing the phone away from heat sources? What temperature should it not exceed?
Yes, there is a recommended temperature range that varies slightly depending on the manufacturer. Typically this range is set between 0 and 35 degrees Celsius. However, some devices can withstand slightly higher or lower temperatures.
Regarding the temperature that must not be exceeded, it is considered that that mobile phones may be damaged at temperatures above 45 degrees Celsius.. At temperatures above this, internal components, especially the battery, are more likely to suffer. Therefore, it is important to avoid exposing cell phones to temperatures above this threshold to prevent potential problems.
What variables cause smartphone temperatures to rise? When thinking about protecting your cell phone from the heat, do you need to consider the climate? Should you be careful in the summer?
Many variables influence the temperature rise of a mobile phone. From intensive or resource-intensive use, such as long periods of gaming, to choosing a thick case and exposure to the sun. Yes. weather is an important factor to consider. It is important to be careful about phones overheating due to high ambient temperatures and exposure to direct sunlight. It is recommended that you do not leave your mobile phone in places exposed to sunlight for long periods of time and try to store it in a cool and well-ventilated place whenever possible. Additionally, reducing heavy phone use during extreme heat can help prevent temperature problems.
Finally, what advice would you give to protect your phone from heat and its harmful effects?
There are many. For example, it is recommended to avoid direct exposure to the sun, especially for long periods of time. If you use covers, make sure they fit. This ensures good ventilation and heat dissipation. You may also want to reduce heavy use of your device during periods of extreme heat, as they consume a lot of resources or require high CPU performance on hot days.
A very useful tip that many people forget: disable unused features. For example, keep features such as GPS, Bluetooth or Wi-Fi when not in use, as they can cause the device to heat up. Moreover, it is very important to keep in touch software phone as these may include improvements in heat management and device performance.
Likewise, apart from the care tips and measures, if the phone gets too hot, you should stop using it, wait for it to cool down and take it to the brand’s official technical service before using it again.
“There are bad habits that can cause serious overheating.”
According to the aforementioned Burshtyn, protecting your mobile phone from the heat is not a trivial task. It happens that sometimes the consequences can be dangerous. “High temperatures accelerate battery degradation, reducing its charging capacity and service life. In extreme cases, the battery can swell or even explode due to internal chemicals.“, notes the expert.

There are many problems caused by heat. What other components are affected besides batteries?
High temperatures can affect the operation of electronic circuits and components, causing temporary or permanent failures. Another important component is the screen, which can become warped or even permanently damaged when exposed to high temperatures.
There are other types of situations. For example, if your phone overheats and it has a temperature sensor, it can automatically turn off to prevent further damage. Another related issue is poor performance and reduced screen touch sensitivity.
In addition, it is necessary to take into account cosmetic damage. For example, deformation of the case, peeling of plastic, rubber or glass gaskets, or peeling paint. Added to this is another undesirable effect – data loss, since heat can damage the memory. Thus, it is important to protect your phone from excessive heat for a long time to avoid these problems.
What habits raise the temperature on your mobile phone?
On the one side, intensive use without turning off the screen. Using games, GPS apps, or watching videos for a long time causes the phone’s temperature to rise. Another variable is Battery charge. The phone gets a little warm while charging, especially if you use a fast charger.
Poor ventilation conditions, such as the use of unapproved lids, should also be taken into account. In addition, it is important to update softwareIn this sense, outdated applications may contain bugs that cause the device to operate less efficiently and overheat.
Finally, there is an environmental problem when the temperature exceeds 30 degrees Celsius. In this moment Exposing your phone to direct sunlight or high ambient temperatures may cause it to overheat..
When we think about how to protect our mobile phone from heat, what happens to a number of habits, such as using it on the windshield of a car?
It is not recommended to use your phone in a car as it will be exposed to direct sunlight. High temperatures inside the vehicle combined with the use of the phone may cause damage. serious overheating.
There is another bad habit: leaving your mobile phone in bed at night. Not recommended, especially if covered with a pillow. Body heat and lack of ventilation can cause overheating. In addition, the pressure may damage the screen or internal components of the mobile phone.

Andres Bursztyn completes the series of recommendations for protecting your mobile phone from the heat:
- Under no circumstances should you give your mobile phone to Sun.
- Avoid using your mobile phone in hot conditions for long periods of time.
- Close applications you are not using.
- Remove the case from your phone if it gets too hot.
- Turn off your phone if it gets too hot and let it cool before turning it on again.
“Phones should also be protected from the sun.”

“Just like we should protect our skin from sun damage (hello, sunscreen!), we should do the same with our phones.” Recommendation provided by Asurion, a company specializing in device repair. Consistent with Burshtyn’s points, they note that one of the riskiest scenarios is leaving a cell phone exposed to heat in a car.
“If your phone overheats, you may experience problems such as battery drain, forced shutdown, and even complete failure. I’m not kidding. The central processing unit (CPU) is capable of melting if temperatures reach extremes,” they warn.
In addition to tips on protecting the phone from heating (by the way, they coincide with those previously discussed), the company recommends actions to cool the phone. “Aerating or blowing air may seem silly, but it’s helpful when it’s too hot.”, they note. On the other hand, sudden changes in temperature are not recommended at all. Therefore, it is not recommended to place the device in the refrigerator if it is too hot. “This is a sure way to ruin everything,” they say.
How to protect your phone from heat and cool it down if necessary? Remove the protective case, turn off Bluetooth and activate airplane mode, especially in areas with poor coverage, to avoid overexertion.
