Crash tests of mobile phones marked "moisture protection". Part 1

As everyone knows, mobile phones are not designed to work in conditions of high humidity and especially under water. For these purposes, there are special waterproof covers and covers. But lately, mobile phone models began to appear on store shelves, in which it is written in black and white: " waterproof ". Or rather, special markings such as ip65 or ip68 are applied. These figures indicate how much and what kind of aggressive environment this or that device will transfer.

There is a good saying: trust, but verify! The GTV channel decided to test the real capabilities of these phones to counteract the water element and took several educational programs from the Hi-Testing cycle.

For the crash test, we took 2 control and 4 phones marked "moisture protection":

1. MTS-140 (control)
2. iPhone 2G (control)
3. Sonim XP3300 Force
4. Samsung Galaxy xCover S5690
5. Sony xperia go
6. Fly OD1

See the first 3 tests under the cut.

The following should be noted:

• The reference models were the budget, a completely new phone from the MTS and the popular, but used iPhone iPhone 2G;
• moisture protection phones of different categories were tested: Sonim XP3300 Force with serious protection for ip68, budget Fly OD1, and medium for protection Samsung Galaxy S5690 and Sony Xperia Go;
• before the crash test, the devices did not understand, so as not to violate the degree of tightness declared by the manufacturer.
  Before the start of the first test, the simulators and the batteries of each device were glued with indicators of moisture, which turn red when touched with water. This will allow us to identify the fact of moisture penetration under the body of the device.

But the iPhone and Sony did not allow us to fully implement our plan with indicators: their batteries can be reached only if the devices themselves are disassembled. And as we said, we decided not to break the tightness of gadgets. On Sony, the indicator was pasted under the decorative cover.

Test number 1: Aquarium

Taking a small aquarium with a depth of 40 cm, we immerse all the phones in it one by one. By actively leaving the bubbles from the control apparatus can be said: the water in them is already waist-deep. This is confirmed when you try to call them.

Test # 2: Pool

To carry out this test, the usual aquarium will not get off and we filled the children's pool with water. A two-meter transparent flask was installed in the center, inside which even a laptop could fit.

Test # 3: Charcot's Douche

Here we will focus on the stream of water under the pressure of escaping from the water "gun". This jet is stronger than tropical rain. The third test is called “Charcot’s Douche” and imitates bathing with a phone under the shower or a walk in the pouring rain.

In a week we will finish the installation of three more tests.

• Test number 4: Centrifuge

  
  One of the classic phrases that customers of mobile phone repair centers say is: “I washed the jeans in whose pocket my phone was lying.” We could not ignore this topic in our experiment. The phones were placed in a transparent centrifuge, which is very similar to a washing machine.
  
  

• Test # 5: Contrast Baths

  
  Recall once again that special waterproof phones are involved in the tests. True, the instructions do not mention what temperature can be water. And if it is not said, we will check the whole range: from 0 to almost 100 degrees Celsius. Maybe water is different.
  
  

• Test 6: Deep Diving

  
  In the last test, we simulate an immersion of 30 meters. This can be safely called a "crash test". Neither the manufacturers nor we, do not undertake to assume what will happen with the devices with such pressure.
