After Motorola “Dai Fei”, how did the three-proof mobile phone gradually disappear?

Recently, a friend approached me to complain that the screen of the mobile phone I had just bought was broken. It happened that I didn't buy the broken screen insurance, so I finally reluctantly spent more than a thousand yuan to replace the screen.

In order to comfort him, I compared him with misfortune: I once broke the screen of Lenovo Music Phone twice, and broke the screen of iPhone 5s three times.

While chatting, I talked about the durability of mobile phones, and then talked about the topic of rugged mobile phones.

An interesting phenomenon is that when it comes to rugged phones, most of the friends around me will think of Motorola's Defy (Dai Fei). In 2010, its birth once made the word rugged mobile phone popular.

The deepest impression is that it combines the "three defenses" and "intelligence", and even has good performance, as well as a restrained and simple design.

But unfortunately, after Di Fei, there is no more famous rugged phone than her. In recent years, the popularity of rugged mobile phones seems to be getting lower and lower, and it is difficult to see them in mainstream reports.

When we are talking about rugged phones, what are we talking about?

There is no precise definition of "three defenses". Under the literal meaning, waterproof and dustproof are certain, but the other "proof" refers to a slightly different product for each product, such as scratch-proof, drop-proof, shock-proof and so on.

Regarding waterproof and dustproof, the parameters we often hear are mainly represented by "IP+digital suffix". For example, Motorola Defy advertised that it had an IP67 protection level, which was extremely rare in the 2010 smartphone camp.

However, the advancement of mobile phone manufacturing technology has also led to constant changes in the definition of rugged mobile phones. For example, Samsung’s recently released Galaxy Xcover 5 can well represent the current three-proof mobile phone standards: IP68 protection level, MIL-STD810H certification.

IP68 is easy to understand. The first number after IP is the solid particle protection level, which represents the product's ability to resist the entry of external solid particles, that is, the "dust level", which is divided into 0-6 levels. The second number is the liquid protection level, which represents the product's ability to resist the ingress of external liquids, that is, the "waterproof level", which is divided into 0-8 levels.

However, a mobile phone with an IP68 waterproof and dustproof rating does not mean that it can be immersed in water indefinitely without damage as described in the table. Water temperature, water depth, and immersion time will all affect its water resistance. IP68 mobile phones generally can withstand staying in water at a depth of 1-2 meters for 30 minutes.

Today, IP68 is no longer a rare parameter. Many flagship phones such as iPhone 12 and OPPO Find X3 Pro are marked as supporting IP68.

For rugged mobile phones, this is tantamount to grabbing their jobs. So in order to save face, the rugged mobile phone began to move out of the MIL-STD810 standard as an endorsement.

Simply put, MIL-STD810 can be understood as a US military-grade standard. The 2019 revision is MIL-STD810H, which replaces the MIL-STD810G released in 2014.

To achieve this certification standard, it needs to be "destructed" by various reliability test items. It mainly includes three directions: mechanical, environmental and life reliability testing.

For example, the drop test in the mechanical reliability test includes directional drop and free drop tests at multiple heights, and the number of drops is also strictly required. The ambient temperature test will give extreme temperature and air pressure conditions, and the phone should work normally within these ranges.

In addition, military-grade standards also test unusual items such as noise, fluid pollution, solar radiation exposure, and sinusoidal vibration. Ensure that the product has stable performance in certain extreme scenarios.

Reaching military-grade standards is already a must-have selling point for rugged mobile phones today. In addition to IP68 and MIL-STD810 standards, certification indicators such as IP69K have also emerged in recent years.

The latter mainly refers to the mobile phone's ability to withstand the hot steam washout test defined in EN 60529 and DIN 40050-9. This can provide protection at a water pressure of 100 bar (1450 psi) and a temperature of 80ºC.

In short, IP69K mainly refers to the pressure to protect the water from scouring.

When we flush the phone with a faucet, the water pressure is often relatively high, which is why there is a risk of water entering the IP68 mobile phone when flushing with water. IP69K is mainly a certification index born for this scenario.

Rugged mobile phones are so "indestructible" that they should be popular in theory. Why is the popularity not as good as before?

Simply put, one is the unpleasant appearance, and the other is the high price and low cost.

Three anti-mobile phones, why are they so ugly?

Rugged mobile phones are not good-looking. In fact, they are not exactly the designer's "pot". One major reason is the limitation of engineering materials.

Today, it is not difficult for mobile phones to be waterproof and dustproof. To achieve this goal, there are usually two options. One is to reduce the splicing of the fuselage, and then use waterproof rubber strips and sealing rings to block the gaps in the fuselage, which greatly increases the waterproof and dustproof capabilities of the fuselage.

This is the idea of ​​structural dustproof and waterproof. This sealing method also has many drawbacks. For example, when the rubber plugs on the earphone jack and the charging hole are deformed, the airtightness of the mobile phone will be damaged, resulting in a decline in the ability to waterproof and dustproof.

This requires the help of nano waterproof technology. To put it simply, the surface of the device is coated with a layer of nano-polymer, and the liquid will condense into droplets when it comes into contact with the coating. Therefore, if liquid flows into the device, it can be discharged quickly.

For rugged mobile phones, these two solutions will basically be used at the same time. Rubber plugs are installed on the charging hole and earphone hole of the fuselage, although it is waterproof and sand-proof, it reduces the exquisiteness of the fuselage.

The appearance killer of the rugged mobile phone is the thick frame. In order to prevent falling, rugged mobile phones mostly use armor-type protection structure, the frame is made thick and large, and the material is mostly Bayer soft glue to improve toughness.

As a result, after meeting the above conditions, the three-proof mobile phone becomes thick and bulky. In the era of beauty in power, it is difficult to arouse the public's desire to buy.

If you want to be waterproof and dustproof, why don't consumers buy a mainstream IP68 mobile phone? Thin and stylish. If you add a silicone protective cover, you can also achieve the purpose of anti-fall. It can be said that the competitiveness of rugged mobile phones is not as good as before.

High price and low distribution, far more serious than expected

Although the competitiveness of rugged mobile phones is gradually declining, it is still a product that is difficult to replace for outdoor workers and enthusiasts.

Looking at the comment area of ​​Taobao's top-ranked smart rugged mobile phones, you can roughly see the portraits of its users: takeaways, express delivery practitioners, outdoor sports enthusiasts, and truck drivers, etc.

These people have high requirements for the durability of mobile phones, but they often ignore the performance of mobile phones. This gives manufacturers a loophole for high prices and low allocations.

Let’s take the top-ranked model in the search results of an e-commerce website as an example. First look at the AGM X5 rugged mobile phone. If you have seen "Wolf Warrior" or "Operation Red Sea", you should have heard of this brand.

The protagonist in "Wolf Warriors 2" uses AGM X2, and "Operation Red Sea" uses AGM X3. X5 is the latest model in this series. In order to prove the popularity of its products, AGM's official customer service stated that "for every 10 mobile phones in the world, 3 are AGM".

What is the basic configuration of the AGM X5 priced at 3699 yuan?

  • Processor: Ziguang Zhanrui T7510
  • Android 9
  • 6.53 inch 1080P water drop screen
  • 8GB+256GB
  • 5600mAh battery, 18W fast charge
  • 48 million pixel main camera + 8 million pixel ultra-wide angle + infrared background blur lens + macro lens (no sensor model announced)
  • Support IP68, IP69K, 810G certification

At 3699 yuan, there are many Qualcomm Snapdragon 888 and 870 models on the market, but the AGM X5 is equipped with a thousand-yuan Ziguang Zhanrui T7510, which is really unreasonable.

Let's take a look at the Doogee S96 Pro rugged phone, which is priced at 2,250 yuan and ranked third on the search results page. Its main configuration is as follows:

  • Processor: Helio G90
  • Android 10
  • 6.22 inch 720P water drop screen
  • 8GB+128GB
  • 6350mAh battery, 24W fast charge, 10W wireless charging
  • 48 million pixel main camera + 8 million pixel ultra wide angle + 20 million pixel night vision lens + 2 million pixel macro lens
  • Support IP68, IP69K

As a rugged mobile phone, it does not support 810G certification, which has no advantage. In addition, judging from the running scores of AnTuTu, the performance of this Helio G90 chip is similar to that of Qualcomm Snapdragon 730, which belongs to the low-end camp. Its 6.22-inch screen is still using a 720P panel, which is a bit "fooling" consumers.

Make use of the parameters that the target group does not understand, and perform subtraction on the configuration of the mobile phone. This phenomenon of high price and low cost is common in mobile phones with the "three-proof" label.

Rugged mobile phones, is it possible to regain the glory?

If the rugged mobile phone wants to capture the hearts of more C-end users, it's time to make a change.

There are three reasons why Motorola Defy went out of the circle at the time. First, the appearance is closer to the daily smart phone, the second is the mainstream configuration, the performance is impressive, and the third is the price is reasonable, and the student party can also accept it.

If a manufacturer can do these three points at the same time, then the rugged mobile phone may once again enter the eyes of the public.

In fact, the AGM brand mentioned above was actually quite impressive when the X2 was launched in 2017. Not only because Wu Jing is the same model in "Wolf Warrior 2," but also because its design can be regarded as a good face among a group of three-defense machines, and the configuration is also close to the Android mid-range model.

However, it is a pity that the appearance design of the subsequent models of AGM has gradually lost the exquisite and aesthetic feelings that it used to be, and it is difficult to find bright spots in the configuration.

In addition, as a vertical mobile phone, personalized functions or services are indispensable. For example, some rugged mobile phones do a good job of positioning, and support GPS+BDS Beidou or GPS+GLONASS dual-mode positioning. Accurate coordinate positioning can also be achieved when there is no card or signal, which is very friendly to outdoor users.

There are also some three-proof mobile phones that emphasize their own explosion-proof technology, and have passed the chemical IIC-level explosion-proof safety certification, which is suitable for employees of chemical companies.

Another example is SF Express, which cooperates with our company. The rugged mobile phone it uses is equipped with a TOF lens. Taking a photo of the express package can quickly calculate the volume and cost, replacing the traditional PDA scanning gun.

This is like the physical shoulder button on a gaming phone, which has obvious scene attributes. However, gaming phones have grown into a branch that cannot be ignored in smart phones due to their strong performance, cool appearance, and rich dessert functions.

Rugged mobile phones, which are also vertical products, may be able to carefully study the rise of gaming phones. Those outdoor workers and enthusiasts deserve better products.
