In the mountains , water is not particularly problematic, as almost all mobiles currently have some protection against moisture and many can be submerged without problems. When in doubt, of course, it is best to think that it is rainfed and not take risks; The second best thing is to look for the model and its IP protection number.

The degree of protection IP (initials of International Protection ) has a figure that is actually two. Thus, the first measures the protection against the entry of solid objects (roughly, dust; the maximum number is 6) and the second is what interests us, since it refers to the ingress of water.

This number can range from 0 (equivalent to a strainer) to 9K (a spacecraft), although from 7 it guarantees protection at a depth of one meter and for half an hour. Thus, an IP67 can be taken a dip - voluntary or not - without much risk.

It should be remembered that the phone must be completely dry before being charged, as humidity can be lethal in combination with current (and not only for the device).

What is usually deadly in need are the falls against the granite (or any other rock, regardless of its composition; in this case the mobile does not get very sticky). A silicone or hard case can absorb much of the shock and save your phone, so it's not a bad idea to get hold of one before you go out.

If the case finally accompanies us and ends up giving its life for that of the iPhone, it is convenient to honor this sacrifice by making it not in vain and assume that it has already fulfilled its function: as with helmets, once a blow has been struck, it must be replaced, even if it seems to have held.

Is the tip late and the screen has cracked? For starters, it shouldn't be a drama; As long as the panel behind the glass has not been damaged, the phone can continue its day to day. In this case, yes, we should treat it as if your IP was at the service of His Majesty: 00. As tiny as the cracks may seem, they can allow the passage of particles or moisture capable of rendering the phone useless.

Lastly, while it is not a protection as such, it always comes in handy to know how to extend battery life for a day in the field. Beyond its telephone uses, the mobile can act as a camera and flashlight, among other things, as long as its autonomy allows it.

In the event that we are in an area with little coverage, the simplest way to increase the resistance is to activate the airplane mode or deactivate the mobile networks and WiFi manually. If they are active, the device will try to search and connect periodically, which has a significant impact on its battery. In addition, since there is no network, there will be many applications that will become virtual paperweights, which will give the screen a rest and, consequently, more hours of use.

Sand, humidity and salt, the enemies on the beach

When changing scenery the dangers are similar (after all, the phone can fall anywhere) except in the case of water, which goes from being an inconvenience to something that can really destroy a phone.

As waterproof as a mobile phone is and regardless of its IP protection grade, salt can corrode external components. In fact, if the phone were to take a bath in the sea, it is recommended to wash it with fresh water and then go to the drying process: in the sun -not direct, it can be set at more than 50 degrees and the terminal is not prepared for it- and never with an electrical appliance (a dryer, for example), since the remedy could be worse than the disease. If it has turned off, do not attempt to turn it on until we are sure that there is no trace of moisture.

The sand acts in a similar way, it has special fixing by the screen and the ports (headphone or charging, mainly). Regarding protection, it is measured with the first of the figures.

It should be noted that although the mobile does not go down with us to the beach, the sand will come back: pockets, bags and backpacks will have grains that will inevitably continue to appear until February if the clothes are not washed carefully.

It is best to try that the phone is never in these places. If finally some grains enter, you should never introduce foreign elements to try to clean it, because then there will be sand and a piece of the strange element that we have chosen. The best? Compressed air. If we do not have on hand, in any store they can fix it in a matter of minutes.
