What is the "IP Rating" of the phone? (+ table)

By Administrator
What is the "IP Rating" of the phone? (+ table)

On most smartphones today (especially Flagship) we can see the label "IPxx", which means resistance to dust and water. But what does "IP" mean? What do the numbers next to that abbreviation mean? Do more numbers mean better protection?

International Protection Rating

IP is abbreviated to "International Protection" (or Ingress Protection *) and is always followed by two numbers:

  1. the first number indicates the resistance to solids (1-6)
  2. the second number indicates water resistance (1-9)

For example, Flagship phones generally have IP68 because it is actually the best protection against water/solids that the phone can have. IP69 phones are a rarity and are mostly certified by those designed for adventurers and construction workers (example).

However, if the phone manufacturer wants its devices to have an IPx8 rating, they will only be tested for IPx7 and IPx8, not lower. There are exceptions, such as the Sony Xperia XZ3 model which has been tested from IP65 all the way up to IP68.

International Protection Rating

* IEC 60529 (Ed. 2.1), clause 4.1

IP Rating – table

If you want to see in detail which number means what, you can look at the table below.

Number one: solids

Level

The size of the unwanted substance

Protection against:
0 No protection No protection against solids
1 >50mm any larger area of ​​the human body, such as the fist.
2 >12.5mm a finger-sized object
3 >2.5mm tools, thicker wires…
4 >1mm most wires, screws, small tools…
5 Dust protection dust breaking is not complete, but the functionality of the device is not compromised. Complete contact protection.
6 Complete dust protection Complete dust protection. Complete contact protection.

Second number: water

Level

Strength

Protection against:
0 No protection The device is not protected against water
1 Dripping water water dripping continuously for 10 minutes
2 Dripping water at an angle of 15 degrees water dripping continuously for 10 minutes at an angle of 15 degrees
3 Water spray spraying with water at any angle, up to 60 degrees from the vertical, for 5 minutes
4 Watering watering for 5 minutes
5 Water jets water jets with a diameter of 6.3 mm from any direction for at least 3 minutes
6 Powerful water jets powerful water jets with a diameter of 12.5 mm from any direction for at least 3 minutes
7 Immersion: up to 1mm immersion in water to a depth of 1m for 30 minutes
8 Immersion: more than 1m immersion in water with a depth of more than 1 mm specified by the manufacturer
9 Strong water pressure from close range continuous spraying with a powerful water jet from close range from any direction - including hot steam nozzles

Water Resistance / WaterProof

And now, after this table, it is not clear to you what is the difference between a Water Resistance and a WaterProof phone? The difference is that the Water Resistance phone can "refuse" a smaller amount of water, and you can soak the WaterProof phone in water.

X96 Mini Android TV Box Review

By Administrator
I have already written an article about buying an Android TV Box for up to 30 euros, and now I am writing about one such device - the X96 Mini TV Box . There is not much to say about this device, its price is around 25 euros, it is an Android TV Box like any other, which means that it is powered by an Android system. Since I wrote about it in the previous article, I will not repeat myself. These cheaper TV Box devices differ mainly only in the chip, amount of RAM, and ROM memory. In the previous article, I wrote about what to pay attention to when choosing, and I chose this device that way.

To click on the post or not?

By Administrator
Recently, Facebook has been flooded with " click bait " posts, and sometimes you don't know if there is something really useful behind that post or if it's just collecting clicks. There is a plugin that can partially reveal this to you. Nothing special, it's a Chrome extension called " Photo Zoom ". What does he actually do? Enlarges the image you hover over by loading the source address of the image . How can it help? Clickbait posts often "trick" users into clicking with an image (in addition to terrible headlines). They place those pictures so that only a part of them is visible on the Facebook wall and just enough to interest your potential. If you want to see the whole thing, you have to click on the link, which is their goal.
