This week's intense heat wave has tested our ability to withstand high temperatures, but living things are not the only ones suffering. Our loyal tech companions, mobile phones, are also affected by the summer heat. Just as we take care of our health during this season, we must pay attention to our devices to prevent excessive heat from damaging their internal components and affecting their performance. Taking into account that on these dates and especially on vacation, we do not detach ourselves from them.

  • Monitor internal temperature with CPU-Z. Although heat isn't always visible on the surface of your phone, it can build up internally. For precise control of component temperature, consider installing apps like CPU-Z (for both Apple and Android), which provides detailed information about your device's internal temperature. This is essential, as the accumulated heat can have a negative impact on the performance and lifespan of the mobile.
  • Keep your mobile in dry places with moderate temperatures. Avoiding overheating starts with keeping your phone in a proper environment. Most manufacturers recommend an operating temperature range between 0ºC and 35ºC. It is important to find a balance, as extremely high or low temperatures can damage the device. Also, be sure to keep it in a place with low humidity, as this can infiltrate and affect the internal components of your mobile. A good way to continue using your device on the beach or pool safely is to buy a waterproof transparent plastic case (although you can also do the fix with a frozen bag). In this way you can protect it from moisture, but remember that tucked into the plastic, the device will be in an environment that reaches a few degrees more than the outside, so do not put it under the sun.
  • Avoid demanding video games. Games on mobile devices are fun, but they can be a major factor in overheating. Graphically demanding games can put a significant load on the CPU and GPU, raising the temperature of the phone. It depends on both the game in question and the device. The more power the terminal has, the less load it will be to run the game and vice versa. Also if you are outside at more than 35 degrees, avoid using your mobile to play video games, whether PUG or Fortnite or Candy Crush.
  • Protect your Mobile from Direct Sun Exposure. Keep in mind that on many occasions the phone is left in the sun, on the table of the beach bar or towel. A dangerous habit that in a matter of a quarter of an hour can cause the phone to reach critical temperatures. A time when the device will usually turn off as a security system, however, it may happen that despite this measure, irreversible damage has occurred. Direct sunlight can be harmful to your mobile, especially in summer. Avoid leaving your device in the sun, as extreme heat can cause long-term damage. Whenever possible, keep your phone in the shade, whether in a pocket, purse or inside a building.
  • Opt for covers that do not retain heat. Some protective cases can trap heat around your phone, potentially leading to an increase in temperature. Look for cases and accessories that are designed for heat dissipation and allow air to circulate around the device. Materials like plastic and leather can retain heat, while others like silicone and mesh fabric tend to be more breathable.
  • Avoid carrying your phone under your pillow or in bed. Although it can be tempting to leave your phone charging under your pillow or near you while you sleep, it's a risky practice, especially in the hot months. The bed and bedding can block the heat dissipation of the phone while charging, which could lead to overheating. It is preferable to load it on a flat and well-ventilated surface.
  • Close background apps. Many apps continue to run in the background even when you're not actively using them. These applications can consume resources and generate heat. Regularly close applications you're not using to reduce CPU load and decrease heat generation.
  • Perform periodic restarts. Restarting your phone from time to time can help free up resources and processes that could be contributing to the warm-up. A restart can help restore the thermal balance of the device and eliminate potential performance bottlenecks.
  • Don't Ignore Heat Alerts. Some phone models have a temperature alert feature that will notify you if the device is getting too hot. If you receive a warning, don't ignore it. Pay attention to these alerts and take steps to cool your phone if necessary.
  • How to Cool Your Mobile Safely. If your phone has become excessively heated, it is important to act quickly and safely to avoid permanent damage. Here are some strategies to cool your mobile:
    • Turn it off completely: Turning off the device will allow all components to gradually cool down by stopping all internal processes.
    • Remove the case: If your phone has a case, remove it to allow better heat dissipation.
    • Place it on a cold and dry surface: Look for a cool and dry surface to place your mobile, which will help reduce the internal temperature.
    • Soft ventilation: You can place your phone near a fan with a gentle flow of air, which will help cool the components.
    • Do not charge it while it cools: Avoid charging your phone while it is cooling, as charging can generate additional heat.
