What does ip mean

Protect your phone from water

The first digit characterizes the protection against solid particles, i.e. dust, the second - from water (moisture). The range of values ​​in the first case can be from 0 to 6, in the second - from 0 to 9 inclusive. The protection of the phone against water and solid particles is determined by the markings described in the table.


First digit

Second digit

0 the device is not protected from dust the device is not waterproof
1 protection against particles wider than 50 mm protection against vertical drops (at right angles)
2 width over 12.5 mm protection against drops at an angle of more than 15 degrees
3 width over 2.5mm from raindrops
4 width over 1.0 mm from splashes
5 dust protection from a jet of moderate pressure
6 complete impermeability of dust from a strong jet
7 from immersion in water for a few minutes
8 from immersion for a long time
9 Completely sealed, protected against high pressure hot jets

For example, the protective smartphone Samsung Galaxy A52 complies with the IP67 standard. This means that the body is complete. prevents even small particles of dust from getting inside (number 6). Also, the device is not afraid of drops, jets of water, rain and even immersion in water for a short time (number 7).

If we consider the choice of a secure smartphone, it should be borne in mind that even a high standard does not provide complete sealing of the case. For example, shooting underwater with such a gadget is still unsafe. This is due to the negative effect of water pressure (especially when diving), as well as the duration of the procedure. For such specialized purposes, it is worth choosing special underwater cameras.

The degree of protection of the phone

Most Common Standards

Determining the degree of protection of the phone is quite simple. In the description of the model, the IP standard is indicated, by which you can understand how well the case and screen are made. As examples, it is recommended to consider the most common standards.


These are mid-range devices, belong to the budget segment. In this case, a protective case for a smartphone completely preserves the gadget from dust, as well as from various effects of water:

  • rain;
  • jets of different pressure at different angles;
  • short-term (for a few seconds) immersion to a depth of 1-1.5 m.

An example is the Samsung Galaxy A72, iPhone SE 2020. Such a phone can fall into the snow and lie on it or under it for a long time, after which it will remain operational. With it, you can be in a dusty area or in a dusty room. It is also allowed to fall into the water, but for a short time. Those. if you immediately remove the gadget, wipe it and dry it thoroughly, it will continue to function normally.


Marking this degree of protection for smartphones means complete protection even against fine dust particles. Safety from water includes all cases described for IP67 and additionally - immersion in water for a long time (up to 30 minutes), but at a shallow depth of 1-1.5 m.

If you answer the question of how to choose a secure smartphone, you can give specific examples of IP68 class models:

  • iPhone 11;
  • Xiaomi Mi 11 Ultra;
  • Samsung Galaxy Note 20;
  • ASUS Zenfone 8.

Such gadgets will quite calmly survive even a relatively long stay under water. But in any case, it is better not to take risks and immediately remove the phone, and then resume its work only after it has completely dried out.


Many users are interested in what is a secure phone of the highest level. These models include gadgets of the IP69 standard. The housing completely blocks the entry of dust particles, as well as water. The standard includes all the cases described earlier, as well as diving to a shallow depth for an unlimited period of time.

IP69 dustproof phones are not common, examples include:

  • OUKITEL WP5 Pro;
  • Blackview BV6600;
  • DOOGEE S86.
Dustproof phones

Protecting your phone case really matters, as falling into water or being exposed to rain can be a critical factor for some models. Since even with careful use such cases cannot be ruled out, it is better to choose models with a good case of a standard not lower than IP68.
