When temperatures drop and the thermometer plunges below zero degrees, our smartphones are put to the test. They need to be protected from wind, humidity but also and above all from cold. Here is a selection of accessories to prevent your phone from catching a cold..
The harmful effects of cold on our smartphones
With winter coming, our bodies are attacked by a whole bunch of viruses. But living organisms are not the only ones fighting the effects of cold. Electronic devices and in particular smartphones do not tolerate negative temperatures .
Why phones turn off by themselves in winter
The battery is by far the most vulnerable component to bad weather. When exposed to freezing cold, the chemical reactions produced inside these small boxes become slower. They cannot then provide all the energy essential for the proper functioning of our smartphones..
As a result, our phones suddenly turn off as if the battery is dead. Fortunately, this problem can be easily corrected. To do this, simply place your mobile in a place protected from wind and freezing cold such as a pants or jacket pocket and then wait a few minutes for it to warm up before switching it on again.
Do not leave your smartphone lying around in the glove compartment of your parked car or in an unheated location. If you intend to spend several days or even weeks in a place where the temperatures are really very cold, you can also consider the purchase of a protective sock. They are found on the net at all prices. Here is a selection of protective socks for smartphones..
Touchscreen no longer responds
Smartphones are not designed for hot weather or extreme cold. If the good old Nokia mobile phones (feature phone) were able to operate down to -30 degrees, our pocket computers equipped with touch screens prefer warmer temperatures.
In certain extreme conditions, it sometimes happens that the LCD screen displays residual streaks when moving objects. These ghost images cause a very unpleasant blurring effect, especially when watching films.
The cold can also affect the tactile responsiveness of screens and cause latency times. In practice this translates into a significant gap between the action (click on the touch screen) and the taking into account of your gesture by the operating system of your mobile.
To fight against these two phenomena, unfortunately there is not much we can do, except put your phone closest to you to warm it up . Note that screens can also crack more easily in the cold. This is another reason to buy a protective shell.
Protect your smartphone against the cold
In the vast majority of cases, the malfunctions that we have just detailed just above are only temporary. If your phone has suddenly stopped after being exposed to the cold for too long, do not switch it on immediately. Let it sit for several tens of minutes in a dry room.
Do not place it near a heat source. You risk damaging it and reducing its lifespan. A rapid rise in temperature promotes the appearance of condensation and can damage electronic components.
Humidity
I won't tell you anything by telling you that smartphones are very sensitive to humidity. If you plan to take your phone to the ski slopes or to areas likely to be snow-covered, it is more than essential to invest in a reinforced shockproof snow cover.
Also try to take your precious phone out of your coat pocket as little as possible. To be sure not to miss any call why not buy Bluetooth earphones or a connected watch. These accessories will allow you to use your smartphone while leaving it warm.
Use a smartphone with gloves
Winter is a difficult time for organizations. A good pair of gloves will keep your fingers warm. Unfortunately this kind of accessory rarely goes well with the touch screens of our phones. 
The thick layer of wool in the gloves acts as an insulator and prevents the interface from being controlled.
Fortunately, there are gloves fitted with electric filaments specially adapted for touch screens. You will be able to write an SMS without fear of being cold in the hands. Note that some phones and especially Samsung models have a glove mode.
