Heavy upgrade! The thousand-yuan machine of red rice is the best in the whole scene

Unexpectedly, the Redmi Note 13 Pro+ can make some big news a month after its release.

Two days ago, Redmi product manager posted a Weibo:

The Note 13 Pro+ is IP69 tested.

Good guy, originally thought that supporting IP1899 on a phone from ¥68 is already a very explosive thing.

I didn't expect that now even the IP69 test has passed.

You must know that this thing basically only appears on professional three-proof mobile phones.

There may be a small partner to ask:

IP68 listens more, what is this IP69?

Oh, it's time for class.

We often hear about IPXX dustproof and waterproof, the full name is "international protection level certification".

There are two numbers in the certification, the front one represents the dust rating and the latter one represents the water resistance level.

The dustproof rating is easy to understand.

From 0 to 6, the higher the number, the better the protection against solid particles*.

But on the waterproof side, there is a loss of complexity.

Although it can also be roughly understood that the higher the number, the better.

But some scenarios, some levels of test focus is different.

For example, "6" waterproof, test a 12.5mm powerful nozzle injection device for at least 3 minutes.

We often hear the "8" in IP68, and the test equipment is continuously immersed in 2m (normal) water for at least 1 hour.

The former detects the ability to resist violent water sprays, while the latter detects the ability to soak for a long time.

Although 8 is higher than 6, the focus of the testing process is different.

The IP69 mentioned at the beginning is also called IP69K.

This 9/9K introduces the "Road Vehicle IP Protection Code" published in Germany in 1993, which is equivalent to an extension of the old standard.

What is the spicy IP69 defense?

The official description is:

WATER 80°C IS DISCHARGED INTO THE SAMPLE AT A WATER PRESSURE OF 80-100BAR FROM THE NOZZLE OF THE SPECIFIED SHAPE.

The amount of water is 14-16 l / min. 

The distance between the sample and the nozzle is 10-15cm, and the outlet direction is 0, 30, 60, 90 degrees horizontally. 

The sample is placed horizontally in each direction for 30 sec, performed while the sample surface is rotated.

I guess some friends didn't understand.

To put it bluntly, it is to test the ability of high-temperature water pressure protection at close range.

Eh, the emphasis is ha.

Often equipped with IP68 on flagship aircraft, although it can be waterproof and immersed.

But when it comes to water vapor, it's really nothing.

Therefore, many people do not dare to take IP68 mobile phones to saunas, hot springs and other places.

After all, the water vapor in these scenes is relatively strong, and the danger factor is directly pulled up N times.

However, IP69K can theoretically withstand this scenario where water vapor invades mobile phones.

Rounding up, it is the gospel of the bathroom singer Yumu.

So, suppose a mobile phone has passed both IP68 and IP69K certifications.

It is equivalent to both anti-foaming and water spray (for a certain period of time), and it is also the most powerful waterproof buff in the current version.

This is also the reason why many three-proof mobile phones on the market will post two certifications at the same time when publicizing.

If two lack one, I am not embarrassed to say that my three-proof performance is good, right?

But let's emphasize it.

IP69K can theoretically face hard and rigid water vapor, but it does not mean that it is 0 risk.

Users may encounter more severe situations than the experimental environment, and the protection ability of the mobile phone may be weakened over time.

And if most mobile phones enter the water, the manufacturer is treated as man-made damage and will not be free warranty.

Although some manufacturers will take "water ingress warranty 1 time" as a selling point.

But the models that have the confidence to engage in such tumultuous operation can be counted on one hand.

After all, the after-sales cost of water intake is too high, and there are many loopholes that can be exploited.

This also brings out the point of view of another part of the machine -

Did waterproofing but no warranty for water ingress, it's better not to do it?

In fact, Redmi product manager also responded to this question when interacting with netizens.

The cost of mobile phone investment to do dustproof and waterproof is not to hope that users take the initiative to throw the mobile phone in a dangerous place.

It is to let the mobile phone occasionally encounter extreme scenes, but also an extra guarantee.

In other words, we can't use the witch cloak as resurrection armor, right?

Overall, having waterproof certification is still better than not.

Although you can't be presumptuous in daily use, you can at least feel a lot more at ease.

As ordinary consumers, we also hope that more manufacturers like Redmi can bring this specification that was only seen in flagship machines to more low-end models.

So...... At that time, can the Redmi K70 series also have an IP68+IP69K dual certification?

I'm still looking forward to it.
