While France is in the grip of a new heatwave episode, which was to reach its peak on Monday 18 July, electronic devices, such as organisms, are being put to the test by the high heat that affects their components and disrupts their function.
Slower speeds, the battery runs out faster, the screen is less bright, smudged or less responsive … Although they now have internal cooling systems, smartphones, such as computers or game consoles, are not designed to operate in extreme temperatures.
The iPhone, like Android smartphones, for example, should be stored at a temperature below 35 degrees to drive optimally. “Using an iOS device in an extremely hot environment can cause a permanent reduction in battery life,” the Apple website states. Same story on the Samsung page where it is written that “it is important to take into account that high temperatures are not beneficial to our phone”.
When the temperature exceeds a certain threshold, iPhone goes into power save mode and displays a warning message. It must then be placed in a cool place and wait until it has cooled down.
“If the internal temperature of the device exceeds the normal operating range, the device then protects its internal components by trying to regulate its temperature,” explains the US company. In this situation, iPhone charging may slow down or stop, the screen may turn black, the radio signal may fade, the device flash may become unusable, and performance may be reduced. .
How do you protect your electronic devices?
Therefore, when mercury rises, it is important to Keep these devices away from the places most exposed to the sun. Outside, it is recommended to prefer places that are shady or protected by an umbrella or a bag. On the road it is advisable to place a smartphone used for route guidance in economy mode and not to charge it when exposed to direct sunlight. In the same way, it’s better Avoid using applications that are too demandingsuch as video games, video editing or HD movies when using your smartphone on the beach in direct sunlight.
Instead, charge your device indoors, switch to airplane mode, and use its original charger to avoid overheating. If, despite all these precautions, you find that your smartphone is overheating, you can too remove its protective cover to improve heat dissipation. Avoid putting it in the refrigerator or immersing it in water because smartphones like humans are very sensitive to temperature shocks. And they will no longer be covered by their warranty when staying in the water.
Home, computers and consoles are also sensitive to high heat. Think of dust off their fan to facilitate their cooling. Avoid using them in small spaces. The hot air released by the machine is better dispersed in a well-ventilated room. It is also recommended not to use them for too long and in contact with heat-sensitive surfaces, such as plastic or fabric, but rather to choose metal or lacquered wooden supports. Portable consoles are no better off: Nintendo recently warned Switch users that the latter is likely to go to sleep if its air intakes and exhausts are blocked and its temperature gets too high.
