"Yes, Stardust 2 can reach 20 full fast charging power even when the screen is on!"
It only took less than two minutes to charge the Stardust 2 in Chen Zifan's hand from 50% to 52%. During this period, the Stardust 2 in his hand was still playing a movie, and the brightness and volume of the movie were adjusted to the maximum. .
what does that mean?
Whether it is the audience at the scene, countless offline stores, or consumers watching the live broadcast of the Stardust conference online, they all understand that Stardust 2 not only makes up for the biggest shortcomings of Stardust 1, but also improves it to a new level.
"In other words, I can lie down and play games at the same time, and charge my phone at the same time?"
Many people got excited, but then came two questions: Does fast charging have any impact on the battery? Are there any safety risks?
Before they could ask questions, Chen Zifan continued: "The batteries of Stardust 2 and Stardust Tablet were simulated in various usage environments in the laboratory and underwent 3,000 charge and discharge experiments. The measured battery attenuation was less than 2%!"
Many people don't actually 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 signboard?
This is just a battery that Stardust Technology sells to other brands. Wouldn’t it be even more powerful if it is used in its own products?
It is generally accepted that Chen Zifan will not continue to boast about Stardust Technology's lithium battery technology at the press conference. Instead, he 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 20 fast charging and classic cars, in order to prevent some media from malicious slander and to make consumers feel more at ease, he still released a video about the battery experiment:
"Fast is the foundation. We not only want to be fast, but also safer! What you have seen is the puncture experiment of Stardust 2, Stardust Tablet and Stardust 1 batteries. We specially selected batteries from other brands for comparison!"
On the left side of the screen is a battery from another brand, and on the right is a battery from Stardust Technology. In the same puncture experiment, the battery on the left immediately bulged and burned, while the battery from Stardust Technology had almost no reaction.
The same was true for several consecutive sets of experiments. The experimenters also ran through the batteries of several products. Except for an extra hole in the battery, there were no problems, 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 abnormality in battery temperature is detected, it will immediately enter the over-temperature protection state to ensure the safety of the phone!"
To add fuel to the fire, Chen Zifan continued: "But just by saying this, everyone doesn'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 the Stardust mobile phone is waterproof. In this case, we will use water of different temperatures to simulate the heating of the mobile phone in a high temperature environment. "
Chen Zifan gave a brief gesture, and several staff members wearing protective clothing came up carrying an experimental table. In front of them was a transparent glass vessel filled with 30% water, which was used to conduct the following experiments:
"We will put Stardust 2 into it, plug in the charging cable to charge, and at the same time play the movie at maximum volume and brightness, and... we will also heat the water to 100 degrees Celsius and boil it for 3 minutes."
Not only the audience was dumbfounded, but also the mobile phone manufacturers. The founder of a mobile phone brand who was watching the live broadcast on Stardust's official website jumped up and cursed: "You are a madman who is riding a horse!"
"Fuck you! It's just a mobile phone, what do you think? I'm really convinced. This year, all mobile phones with more than 3,000 units will be reserved by Stardust Technology..."
In the past, there was the price-reduced Stardust 1, and later there was the new Stardust 2... In the price range above 3,000, in the range of smartphones, Stardust Technology's market share in China may reach a level that is beyond the reach of all manufacturers.
Chen Zifan wants to use this violent method to instill some concepts in people's minds: Stardust products are of good quality, highly durable, and safe, especially the last point
, it simply pokes at the pain points 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 over-temperature protection is. However, things developed beyond their expectations and they could not control their emotions:
"Holy crap! Holy crap! Are you serious?"
"Can I kneel down for you? If you don't want the phone, you can give it to me! Why bother with it like this!"
"Isn't this impossible? Waterproof doesn't mean it can withstand high temperatures! Boiling vapor is much more powerful than water..."
"Why do you care so much? That's it!"
"It's heating up! Hurry up! Take pictures!"
"..."
In Chen Zifan’s memory, some top flagship mobile phones of some brands will use IP68 dustproof and waterproof to flaunt their flagship status, but whether they can reach this level... I am afraid only the manufacturers themselves know.
There is another level above IP68: IP69K, which can be washed away by high-temperature water vapor. Such products are generally only seen on top-grade rugged mobile phones.
Stardust 2 naturally cannot reach the level of IP69K, but it is still able to withstand boiling water for three minutes. As the temperature rises, the temperatures of the water temperature thermometer and battery thermometer also rise, but there are obvious differences between the two.
When the water temperature rises to nearly 50, the battery temperature of Stardust 2 is only 35.9, and this is while playing a movie and charging. When the water temperature reaches 55, the battery temperature changes significantly.
It increased in a straight line from 35.9 to 41.3, but the over-temperature protection still did not appear at this time. When the water temperature approached 60 and the battery temperature approached 45, the interface of Stardust 2 responded:
First, charging was cut off to protect the battery. Then the movie stopped playing. After a blurry transition animation, a red thermometer appeared on the screen, with a prompt below that the current temperature of the phone was abnormal.
Chen Zifan ignored it and continued to let the phone continue to heat up. The staff originally wanted to put a protective mask on him, but he refused without thinking.
The major media seized this opportunity and took pictures one after another. I don't know what press releases they will write in the future, but now is not the time to care about this.
When the water temperature rose to 80, Stardust 2 had already entered the shutdown state, and the battery temperature could no longer hold up, soaring to 78, which is close to the water temperature.
When the bubbles rose from the glassware one after another... the entire audience couldn't help but cheer. It had been too long since they had seen a product from a domestic manufacturer achieve this level of success at a press conference. .z.br>
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 poor. Mobile phones are not as good as international brands, and cars are not as good as imported or joint venture brands...
But the emergence of Stardust Technology broke this concept. Just three months after the release of Stardust 1, it blocked everyone's mouth with sales of nearly 10 million units. Even if they pinned their hopes on Apple and Android, it was of no use.
The appearance of Stardust 2 was a hit right from the start, with 20% fast charging and ultra-high safety battery... But that’s not the end yet. After the 3-minute boiling time, Chen Zifan took out the Stardust 2 with tweezers and placed it in cold water. middle.
After cooling down for about half a minute, he took out Stardust 2, briefly wiped away the moisture around it, and pressed the power button. At this time, the audience at the scene and watching the live broadcast of the Stardust press conference held their breaths.
When they saw the rising meteor...
The cheers couldn't stop anymore. Stardust 2, which had withstood a series of force tests, was not only turned on, but could also be used normally. After plugging in the charging cable, the lightning logo representing fast charging also appeared. in the screen.
Not to mention consumers, even the top executives of major mobile phone manufacturers who were used to seeing big waves couldn't help but think of a Stardust 2 for themselves. After thinking about it carefully, they realized Chen Zifan's intention.
Moreover, boiling a mobile phone in boiling water is not too difficult to achieve. It only needs to be waterproof and shut down directly after reaching a certain temperature. After cooling, as long as the quality of the mobile phone passes the standard, it can be restarted and used normally.
But consumers don’t think so.
, Stardust Technology is the first smartphone brand that dares to do this, and uses this violent method to directly tell them: the production level of Stardust mobile phones is good.
Even if other mobile phone manufacturers or so-called bricks-and-mortar manufacturers come forward to explain, consumers will not listen. Stardust Technology has conducted experiments on site. This is the "fact". If you want to deny the fact, you have to provide evidence.
Do you have the ability to try it with your mobile phone?
Taking a step back, their mobile phones can also work, so what? Stardust mobile phone has already taken the lead, isn’t the rest just a poor imitator?
Moreover, the really great things about 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 the introduction, but the audience was too enthusiastic. His several gestures had no effect. He had to wait for their enthusiasm to subside for two minutes before continuing to introduce the other configurations of Stardust 2:
"The speed of the amazing speed interface is not only reflected in the fast charging speed. In wired connection mode... our file reading and writing speed and data transmission speed... also have a qualitative leap. Please take a look:
In my hand is a fast USB cable, which 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 fast USB interface, some content in Stardust OS2.0 was also introduced. File transfer is also an important improvement of Stardust OS2.0.
Next is the familiar hardware improvement: the 5.4-inch Retina screen has a color display of 6 million colors, and the color display accuracy and screen brightness have also been greatly improved compared to before.
The curved electroplated frosted metal frame + smoother transitions significantly improve the hand feel. The emergence of the front camera unlocks more usage scenarios and makes it more attractive to female users.
Now some viewers have finally realized why so many people on the Internet want to come to the Stardust conference. This kind of fanatical atmosphere and dizzying configurations... how can it not be exciting?
"We hope that starting with Stardust 2, we will usher in an era of fast charging dominated by fast charging. 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 senior executives of major mobile phone manufacturers, Chen Zifan is extremely ambitious. How could 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 immersed in discussing things about Chen Zifan:
"What a wolfish ambition!"
"It's not about ambition, I can only say that he is a formidable young man. I heard that Chen Zifan's research ability is very strong. It would be great if he could come to our research institute..."
"Yeah, he didn't go to university, but his R&D capabilities are incredible. Many of Stardust Technology's new products were created by him, but if you want to recruit him into the research institute, forget it. Stardust Technology has no way out and needs to he."
"Why is there no way out?"
"..."
Chen Zifan on the press conference stage was still narrating: "We believe that a 5.4-inch screen can bring a better visual experience and is very comfortable to hold, but it still belongs to the category of small and refined..."
After hearing Chen Zifan's introduction, many people couldn't help but complain: What is that? 5.4 inches is still small?
"Isn't it? This is already a super-large-screen mobile phone, okay? The first time I was shocked when I grew up was the 4.8-inch screen on Stardust 1. Now it has been upgraded to 5.4 inches, and it still feels small!?"
"But... if you 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. Just talking about mobile phones, Stardust 2 is already the most comprehensive and capable smartphone on the market!"
"Not only can it play games, you can't find a phone in the world that is better than Stardust 2!"
"Actually, there are still some..."
"??? Come on, you
Tell me? "
"Stardust 3? Stardust 4?"
"get out!"
"To be honest, Stardust 2 is perfect enough, with 360° and no blind spots. I can't imagine how the next generation of products will be upgraded. You will definitely not lose money if you buy Stardust 2!"
"You said the same thing last time..."
If you have to pick a shortcoming of Stardust 2, there may only be one: 2G network. Before the 3G licenses were issued, it would not be the time for the explosion of smartphones. However, the 3G network was not only difficult to use, but also had major flaws.
Chen Zifan could forcibly combine 3G communication technology with some existing 4G research to create 4G communication technology through [synthetic creation], and come up with 4G chips, but the problem of signal base stations is very time-consuming.
This kind of thing cannot be rushed. Compared with Stardust 2, Stardust Tablet does not have the trouble of 2G network because it does not even have an SI card slot...it can only use Fi.
“The size of Stardust 2 does not bring enough impact when processing some work and viewing images, so we hope to develop a product that is both portable and immersive, and can handle work and study tasks.
It is the second product we bring to you today: Stardust Tablet PC. I believe many people have watched our promotional videos before and already have a rough and intuitive understanding of this product. "
