Well, we have to admit that we like the sun. On the other hand, our smartphones don’t. Especially if you think you’re going to forget it in the sun. Who hasn’t ever left his phone lying on a terrace table in the sun?
Therefore, it’s better to be cautious and not leave your mobile companion lying around, as the consequences can lead you to repair it or to have to buy another smartphone. Here are two risks your phone incurs.
Battery failure
Batteries hate heat. And the risk is obviously to ruin it completely. Batteries can’t withstand extreme heat. Above 60 °C, the failure of the battery is for sure.
60 °C is fortunately unimaginable in most areas. That’s true, but we didn’t specify that you had to reach 60 °C for the battery to start suffering — the cells contained in the lithium-ion work better in a comfortable environment with temperatures between 20 and 25 °C maximum. Apple, for its part, makes sure that its iPhones are resistant to temperatures ranging from 0 to 35 °C.
Unstable screen
Generally, users (though not all) leave their smartphone somewhere with the screen facing up. Therefore, in case of intense heat, it is this component that will be affected in the first place. Even the best smartphone screens, whether AMOLED or LCD, cannot withstand a good heat wave without blinking.
Then you may see instabilities in the animations or even areas that would not have been able to withstand the high temperatures that would reveal small dots. And of course, the most visible will be an incorrect response to your actions on the touchscreen. It may seem obvious to everyone, but it’s not uncommon for us to put our smartphones in the heat: in the office by a window, in the car, on a table on the terrace, and so on.
Deterioration of the internal components
Again, this is quite logical, but the downside of overheating components is that the damage is not necessarily immediately visible.
If your display shows signs of weakness quickly enough in the event of overexposure to the sun, this may not necessarily be the case for the other components.
Whether it’s the processor, photocells, antenna, or any other internal component, overexposure can significantly weaken them. At extremely high temperatures, some parts of the printed circuit board may even melt (well, you still have to go very hard or live in the middle of the desert). Before you get there, you’ll also notice a general slowdown of your device.
However, micro-welding can suffer a blow and failures can occur several days or weeks later. You should be very careful and avoid wanting to tan smartphone.
