Chapter 359 Alarming the Finnish Laboratory (3 more)
Gao Miao had no way to go home to celebrate the New Year, so she had to work overtime in the factory.
The factory does have a large amount of raw materials for producing lithium batteries, but to produce these raw materials into lithium batteries, all the lithium battery production factories and production lines in Jiangzhou can only be mobilized.
After arranging the company's affairs, Chen Xiao prepared to return to Jiangcheng for the Spring Festival.
Shen Wei has already made several calls urging Chen Xiao to return to Jiangzhou for the New Year.
Chen Xiao joked on the phone: "You are so anxious to urge me, do you want to invite me to your home to celebrate the New Year?"
Shen Wei just laughed and dismissed this question.
She wouldn't dare take it home.
The social atmosphere in 2002 is incomparable to that of later generations.
Ten or twenty years from now, you can fall in love, get married, and have children in college. If you have the ability, you can take down the teacher.
But it's not possible now. Although many college students are in love, they do so secretly, let alone open it to their families.
Society’s definition of college students is still “students”, not “adults”.
Shen Wei's relationship with Chen Xiao is also a bit strange now.
The two were classmates in high school, but they still kept in touch in college, and their friendship was far beyond that of classmates.
During the summer vacation, Shen Wei also interned in Chen Xiao's company for several months.
To say that the two of them are lovers doesn't seem like it.
Neither of them expressed their friendship to each other, nor did they hold hands and kiss each other.
However, they both have each other in their hearts.
Shen Wei heard Chen Xiao joking and asked to take him home, which caused ripples in her heart.
But she didn't have the courage to really do this.
Shen Wei's tutor is very strict and she is not allowed to bring boys home in college.
Chen Xiao saw Shen Wei hesitating on the phone and didn't know how to answer. He stopped joking and said, "Tomorrow is the 29th of the Lunar New Year. I'll be back and you can come to my house for dinner."
"My parents have always heard me talk about Shen Wei and Shen Wei. They don't know how tall, short, fat or thin Shen Wei is."
Shen Wei felt embarrassed for a while, "Go! You want to be as tall and thin as you want!"
Girls’ concerns are indeed different!
Xia Guo is celebrating the Spring Festival happily, but Nokia headquarters in Europe is extremely nervous.
In 2000, Ericsson released the R380sc mobile phone.
This is the world's first Symbian mobile phone, and also the world's first touch screen mobile phone. Although it has a black and white screen, it is still popular all over the world. It is a well-deserved king of mobile phones and a luxury product among mobile phones.
The status of this mobile phone in the hearts of users at that time was even more important than the status in consumer centers when Apple IP4 came out.
The Symbian era started in 2000, but due to price reasons, Symbian has not yet become mainstream.
In recent years, with the further deepening of globalization, the integration of the global industrial chain, and the development of science and technology, the production cost of mobile phones has been greatly reduced, and Symbian system mobile phones have also entered the market step by step, affecting users' usage habits.
In 2001, in the US market and most European markets, the sales of Symbian mobile phones were tied with feature phones, which explains the problem.
Nokia's ambition is not to be the second or third player in the mobile phone industry, but to be the leader.
Throughout the last year, Nokia engineers have devoted their efforts to design a perfect product. They believe that once this product comes out, it will definitely become the king of mobile phones.
But this product is missing a piece of the puzzle - lithium battery.
Now, Simpson brought the lithium battery back from Xia Kingdom and completed the last piece of the puzzle.
Finland, Nokia Communications Laboratories.
Engineers installed Changtian Technology's lithium battery into a mobile phone named "7650".
There are four groups of mobile phones tested, each group has five mobile phones in total, 20 mobile phones in total. In addition to one lithium battery equipped with Changtian Technology, each group is equipped with ordinary nickel-cadmium batteries, such as Panasonic, Toshiba and Samsung.
of lithium batteries.
The purpose of this test is to know the actual use effect of lithium batteries and traditional nickel-cadmium batteries on mobile phones.
The tests of the four test groups also indicate the four stages of the mobile phone use process.
Standby power consumption test, usage power consumption test, call power consumption test, and comprehensive power consumption test.
The latter item is to simulate the comprehensive behavior of users using mobile phones.
After several days of testing, Nokia Communications Laboratory obtained an astonishing data.
Because it is equipped with the Symbian system, the mobile phone is no longer an ordinary feature phone. The "7650" also has functions such as photography, music, and file editing.
Among them, the nickel-cadmium battery has a combined use time of less than two hours before it burps and runs out of power.
This also proves that Nokia's judgment is correct. New mobile phones must not use nickel-cadmium batteries.
No matter how awesome your phone’s functions are, it’s all useless without suitable battery life.
With the same size and appearance, Toshiba and Samsung's lithium batteries perform equally well and can last for about 5 hours.
This battery life is still not enough, after all, the power consumption during actual use will be shorter than in the laboratory.
Panasonic's situation is better. The battery's listed capacity is 830 mAh, but because the actual energy density is greater, the battery life is about two hours longer.
That is to say, if you use a Panasonic battery, the Nokia 7650 can last for about seven hours.
Users certainly do not use their mobile phones all the time, so the combined usage time can reach 25 or 6 hours, which is about a day.
This is enough for a smartphone!
There is no problem with the one-day battery life, but the user needs to charge it every day. The habit of charging a feature phone and using it for a week needs to be changed.
What surprised Nokia engineers the most was Changtian Technology’s lithium battery.
Panasonic's lithium battery can reach 830 mAh, which is already very impressive. Changtian Technology has achieved 1480 mAh in the same size.
During the testing process, the actual performance was much more exciting than the numbers.
Mobile phones using Changtian Technology lithium batteries can often be used continuously for 16 hours.
That is to say, according to the user's normal usage habits, the actual intermittent use time can reach about two to three days.
This battery life is almost the same as some feature phones with many additional functions!
"GOD!"
Nokia engineers exclaimed.
The performance of Changtian Technology’s battery is amazing!
"Jason, is Changtian Technology a Toyo company? Why is it even more powerful than Panasonic's batteries?"
After getting the experimental results, Nokia engineers talked among themselves.
"Avi, I haven't heard of Changtian Technology either."
"This is Xia Guo's company. They make carbon crystal memory and carbon crystal hard drives, but I didn't expect that they are so good at making batteries!"
"It's actually Xia Guo's company!"
"And I heard that the price of Changtian Technology lithium batteries fully meets our requirements, and the price is lower than Panasonic lithium batteries."
