Erfurt / Berlin You should also remove any cases and, above all, do not put mobile phones in your pocket, advises the consumer center Thuringia. In both cases, there is a risk of heating up and a build-up of heat. The devices are better stored in a handbag or backpack.
Sweat is also a danger if a device is worn close to the body and is not explicitly protected from water penetration. Because then, under certain circumstances, moisture can penetrate into the device and damage it.
Just don’t put it in the fridge
That’s why it’s not a good idea at all to put your smartphone and co in the fridge to cool down, warn the consumer advocates. Dangerous condensation can form in the device.
Overheated devices that have switched off themselves should first be left for some time and not immediately try to turn them on again.
But how exactly does heat affect displays or batteries? It can damage the small liquid crystals or light-emitting diodes in the screen, so that the display only shows incorrectly or no longer shows anything at all, explains the telecommunications portal “Teltarif.de “. And batteries lose their charge faster in the summer sun. In addition, manufacturers warned against charging batteries at temperatures above 40 degrees.
Window sill and dashboard as dangerous places
Not only outdoors, but also in rooms, you should make sure that mobile devices are in the shade. Especially behind window glass, for example on the windowsill, the sun’s rays are extremely concentrated.
The risk of overheating is also particularly high if the devices remain on the dashboard in the car, explains “Teltarif.de “. There the temperatures quite often climbed to 60 or even 70 degrees Celsius.
