Chapter 76 Boiling Experiment
"Yes, Stardust 2 can reach 20W full-load fast charging power even when the screen is on!"

只见陈子凡手里的星尘2从50%充到52%仅仅用了不到2分钟，期间他手里的星尘2还在放着一步电影，并且电影的亮度、音量都调到了最大程度。

what does this mean?
Whether it's the audience at the scene, or countless offline stores, or consumers who watched the live broadcast of the Stardust press conference online, they all know that Stardust 2 not only makes up for the biggest shortcoming of Stardust 1, but also raises it to a new height.

"That is to say, I can play games while lying down in the future, and can I charge my phone at the same time?"

Many people are excited, but then there are two questions: Does fast charging have any effect on the battery?Will there be some security risks?
Before they could ask questions, Chen Zifan continued: "The batteries of Stardust 2 and Stardust Tablet have simulated various usage environments in the laboratory, and conducted 3000 charge and discharge experiments, and the measured battery attenuation is less than 2%!"

Many people actually don’t understand what this concept is, but it doesn’t hinder their enthusiasm. Who doesn’t know that in the field of electric vehicles, just hanging a lithium battery produced by Stardust Technology is better than their own signs?

These are just the batteries that Stardust Technology sells to other brands. Wouldn't it be even more powerful to use them in your own products?
It is recognized by everyone that Chen Zifan will not continue to boast about Stardust Technology's lithium battery technology at the press conference, but will focus on practical uses and the safety of fast charging that consumers are most concerned about.

Although in his opinion there is no difference between 20W fast charging and classic cars, in order to prevent malicious slander from some media and reassure consumers, he still released a video about the battery experiment:

"Fastness is the foundation. We must not only be fast, but also be safer! What you have seen is the puncture test of the batteries of Stardust 2, Stardust Tablet and Stardust 1. We deliberately selected batteries of other brands for comparison!"

The left side of the screen is a battery of another brand, and the right side is a battery of Stardust Technology. In the same puncture test, the battery on the left immediately bulged and burned, but the battery of Stardust Technology hardly responded.

The same is true for several consecutive experiments. The experimenters also cycled the batteries of several products. Except for an extra hole in the battery, there was no problem, which is enough to prove the stability of the Stardust lithium battery.

"At the same time, we have installed an over-temperature protection device under the battery of Stardust 2 and Stardust Tablet. Once an abnormal temperature of the battery is detected, it will immediately enter the over-temperature protection state to ensure the safety of the phone!"

In order to add fuel to the fire, Chen Zifan continued: "But I just said that, and everyone didn't have an intuitive impression. What exactly is over-temperature protection? What effect will it have in actual use?

We can conduct another experiment. Everyone knows that Stardust mobile phones are waterproof. In this case, we will use water of different temperatures to simulate the heating of mobile phones in high-temperature environments. "

Chen Zifan gave a brief signal, and several staff members in protective clothing came up with a laboratory table. In front of them was a transparent glass vessel filled with water at 30°C, which was used for the following experiments:
"We'll put the Stardust 2 in it, plug in the charging cable to charge it, play a movie at maximum volume, maximum brightness, and... heat the water to 100°C and boil it for 3 minutes."

Now not only the audience was dumbfounded, but even the mobile phone manufacturers were also dumbfounded. The founder of a certain mobile phone brand who was watching the live broadcast on Stardust's official website jumped up and cursed: "You are crazy!"

"I'll fuck you! It's just a mobile phone, what do you care about? I'm really convinced. This year's mobile phones worth more than 3000 will probably be booked by Stardust Technology..."

There was the Stardust 1 with a reduced price before, and the new Stardust 2 later... The price range above 3000, in the range of smartphones, the market share of Stardust Technology in China may reach a height that all manufacturers can't match.

Chen Zifan wanted to use this violent method to instill some ideas in people's minds: Stardust products are of good quality, high durability, and strong safety, especially the last point, which directly hits the sore spots of Chinese consumers.

This kind of experiment can be said to be full of BUFF. The audience at the scene originally thought that Chen Zifan was just demonstrating what overheating protection is, but the development of things exceeded their expectations, and they couldn't control their emotions:
"I rely on it! I rely on it! Is it true?"

"I knelt down for you, okay? Don't give me your phone! Why are you making such a fuss about it!"

"Is this impossible? Water resistance does not mean high temperature resistance! Boiling water vapor is much more powerful than water..."

"Why do you care so much, it's over!"

"It's heating up! Hurry up! Take pictures!"

"..."

In Chen Zifan's memory, some brands' top flagship mobile phones will use IP68 dustproof and waterproof to flaunt their flagship status, but whether they can reach this level... I am afraid that only the manufacturers themselves know.

There is another level above IP68: IP69K, high-temperature water vapor washing, such products are generally only seen on top-level rugged mobile phones.

Stardust 2 naturally cannot reach the level of IP69K, but it is still no problem to resist boiling water for 3 minutes. As the temperature rises, the temperature of the water temperature thermometer and battery thermometer also rises, but there is a significant difference between the two.

When the water temperature rises to nearly 50°C, the battery temperature of Stardust 2 is only 35.9°C, and this is still in the case of playing a movie and charging. When the water temperature is heated to 55°C, the battery temperature does not change significantly.

From 35.9°C to 41.3°C along a straight line, but the over-temperature protection still did not appear at this time, until the water temperature was close to 60°C and the battery temperature was about 45°C, the interface of Stardust 2 reacted:
The first is to cut off the charging and protect the battery, and then the movie stops playing. After a blurry animation, a red thermometer appears on the screen, and there is a reminder that the current temperature of the mobile phone is abnormal.

Chen Zifan didn't care, but continued to let the phone continue to heat up. Originally, the staff wanted to wear a protective mask for him, but he refused without thinking.

The major media seized this opportunity and took photos one after another. They don't know what press releases will be written in the future, but now is not the time to care about this.

When the water temperature rose to 80°C, Stardust 2 had already entered the shutdown state, and the battery temperature couldn't hold back anymore, soaring straight up to 78°C, which is close to the water temperature.

When the bubbles rose from the glass container one by one... the audience couldn't help but cheered. It had been too long since they had seen a product from a domestic manufacturer that could do this at a press conference.

People are prejudiced against domestic brands. In addition to some psychological factors, the most important reason is that the products of some domestic manufacturers are really bad. Mobile phones are not as good as international brands, and cars are not as good as imported and joint venture brands...

But the emergence of Stardust Technology has broken this concept. In just three months since the release of Stardust 1, the sales volume of nearly [-] million units has blocked everyone's mouths. Even if they pin their hopes on Apple and Android, it is useless.

The appearance of Stardust 2 is even more explosive at the beginning, 20W fast charging + super safe battery... But this is not over yet, after the 3-minute boiling time is over, Chen Zifan uses tweezers to take out Stardust 2 and put it in cold water middle.

After cooling down for about half a minute, he took out the Stardust 2, wiped the surrounding water briefly, and pressed the power button. At this time, the audience and the audience watching the live broadcast of the Stardust press conference held their breaths.

When they saw the rising meteor...

The cheers could no longer be stopped. Stardust 2, which has survived a round of violent experiments, not only turned on, but also can be used normally. After plugging in the charging cable, the lightning symbol representing fast charging also appeared on the screen. .

Not to mention consumers, even the executives of the major mobile phone manufacturers who are used to the turmoil couldn't help thinking of a Stardust 2 for themselves. After thinking about it carefully, they realized Chen Zifan's intentions.

Moreover, boiling the mobile phone in boiling water is not too difficult to achieve. It only needs to be waterproof, and it will be turned off directly after reaching a certain temperature.

But consumers don't think so. Stardust Technology is the first smartphone brand that dares to do this. It directly tells them in this violent way: Stardust mobile phones are made at a good level.

Even if other mobile phone manufacturers or so-called brick-and-mortar manufacturers come forward to explain, consumers will not listen. Stardust Technology has conducted experiments on the spot. This is a "fact". If you want to deny the facts, you have to produce evidence.

Do you have the ability to try with your mobile phone?
Taking a step back, their mobile phones can also work, so what?The Stardust mobile phone has been preconceived, isn't the rest just poor imitators?

Besides, the really powerful things of Stardust 2 are not only over-temperature protection, high temperature resistance, battery safety... These things, other configurations are also top-notch.

Chen Zifan wanted to continue introducing, but the audience was too enthusiastic, and he signaled several times to no avail, so he had to wait for their enthusiasm to drop for 2 minutes before continuing to introduce other configurations of Stardust 2:
"The fast interface is not only reflected in the fast charging speed, but also in the wired connection mode... Our file reading and writing speed, data transmission speed... There is also a qualitative leap, please see:

In my hand is a super-speed to USB cable. It can be plugged into Stardust 2 and Stardust Tablet. As a small portable computer, it can read files in U disks and card readers, and can also save files in it... "

When introducing the super-fast USB interface, it also brought out some content in Stardust OS2.0 by the way. File transfer is also an important improvement of Stardust OS2.0.

The next step is still the familiar hardware improvement: the 5.4-inch retina screen has reached 600 million colors in color display, and the color display accuracy and screen brightness have also been greatly improved compared to before.

The metal frame with arc-shaped electroplating matte process + smoother transition has a significant improvement in the grip feel. The emergence of the front camera has unlocked more usage scenarios and increased its attractiveness to female users.

Now some viewers have finally realized why so many people on the Internet want to come to the Stardust press conference. This kind of fanatical atmosphere and dizzying configurations... how can it not make people excited?
"We hope that Stardust 2 will start an era of fast charging dominated by super speed. This kind of fast charging is not only fast charging for mobile phones, it should be applied in a wider range of fields to provide convenience for our lives..."

As expected by the executives of the major mobile phone manufacturers, Chen Zifan is ambitious, how can he be satisfied with such small achievements in the mobile phone field?

In the second row of the conference center, two old men with white beards were discussing about Chen Zifan:

"Wolf ambition, this is it!"

"It's not considered a wolf ambition, it can only be said that the younger generation is formidable. I heard that Chen Zifan's research ability is very strong. It would be great if he could come to our research institute..."

"Yeah, I didn't go to university, but my research and development ability is unbelievable. Many new products of Stardust Technology are made by him, but if I want to recruit into the research institute, forget it. Stardust Technology has no way out, and I need he."

"How could there be no retreat?"

"..."

Chen Zifan on the press conference stage is still narrating: "We believe that the 5.4-inch screen can bring a better visual perception, and the grip is very comfortable, but it still belongs to the category of small and fine..."

After hearing Chen Zifan's introduction, many people couldn't help complaining: What is it? 5.4 inches is still small?

"Isn't it? This is already a super-large-screen phone, okay? The first time I was so big was the 1-inch screen on the Stardust 4.8. Now it has been upgraded to 5.4 inches, and it still feels small!?"

"But... if you want to compare it with the Stardust tablet next to it... the screen of Stardust 2 is really not that big, but the size of the Stardust tablet can't be stuffed in your pocket!"

"That thing already belongs to a computer, not a mobile phone. In terms of mobile phones, Stardust 2 is already the most comprehensive and capable smartphone on the market!"

"It's more than capable of calling. You can't find a stronger phone than Stardust 2 anywhere in the world!"

"Actually, there are still..."

"??? Come on, tell me?"

"Stardust 3? Stardust 4?"

"get out!"

"To be honest, Stardust 2 is perfect enough, with 360° without dead angles. I can't imagine how the next generation product will be upgraded. Buying Stardust 2 is absolutely worth it!"

"That's what you said last time..."

If you have to pick the shortcomings of Stardust 2, there may be only one: 2G network. The 3G license has not been issued, and it is not yet the time when the smart phone explodes, but the 3G network is not only not easy to use, but also has serious defects.

Chen Zifan can forcefully combine 3G communication technology with some existing 4G research to create 4G communication technology through [synthesis and creation], and take out 4G chips, but the problem of signal base stations is very time-consuming.

This kind of thing can't be rushed. Compared with Stardust 2, Stardust Tablet doesn't have the trouble of 2G network, because it doesn't even have a SIM card slot...it can only use wifi.

"The size of the Stardust 2 is not strong enough when dealing with some work and viewing images, so we hope to develop a product that is portable, immersive, and able to handle work and study tasks.

It is the second product we bring to you today: Stardust Tablet PC.I believe that many people have watched our promotional video before, and already have a general intuitive understanding of this product. "
