First, chip.

Zhang Yiming summoned Deng Haiyang and others to make final corrections to the chip and finally cleared those subtle problems that may exist or occur.

TMX222 is his sword-drawing work in Zhang Yiming's heart.

He hopes that one day in the future, when someone recalls the development history of mobile phones, he will suddenly think of TMX222.

Just like the motoV3 that will be launched soon, almost all people born in the 1970s and 1980s have an extremely deep and clear impression of this phone.

What he wants is a more popular sales than MOTOV3.

Second, the game.

This is a performance that Zhang Yiming cares very much about. If the built-in chip is the flesh and blood body of TMX222, then the game is the finishing touch.

Currently, there are also built-in games on the market, but they are all single, snake-eating, and small games full of ancient and unchanging atmosphere. If a game like defending the Mushroom House can be built into the mobile phone, not to mention anything else, young people will definitely flock to it.

Because the relationship between Zhang Yiming and Helian Gang itself is good, and Zhang Yiming promised that Helian Gang could benefit from this game, Helian Gang spent all his energy besides normal work to protect the built-in of the Mushroom House mobile phone.

There is a saying that there is nothing difficult in the world, only those who are determined to be interested.

Heliangang was originally a master in this field. With his research day and night, when Zhang Yiming found Heliangang, Heliangang directly handed the complete built-in program to Zhang Yiming.

Zhang Yiming took a deep breath and it was really pleasant to work with such a person.

Third, the phone case.

Because TMX222 is a tablet phone.

Moreover, the latest LCD display is used, and in terms of appearance, it will break through several limitations of current mobile phones.

First, the screen area will increase, second, the thickness of the phone will become thinner, and third, the charging diameter will be transferred.

This puts forward relatively strict requirements on the phone case.

The mobile phone case should not only be beautiful and familiar, but also be thin, but also play a good role in wrapping and shock absorption on the mobile phone screen.

Although the previous fiber shell was of good quality, it could not meet the thickness.

After Zhang Yiming went to H Country, Cong Yu led his team to engage in the crazy R&D process.

Of course, such crazy R&D is not simply about providing support to Zhang Yiming, but more importantly, Cong Yu can see huge business opportunities from this R&D.

Nowadays, domestic electronic products are beginning to emerge like mushrooms after a rain, but there are only a few manufacturers specializing in shell production. Many of them are ordinary plastic or high-refining film manufacturers who temporarily switch to production or produce shells. The quality and technology cannot be guaranteed.

If they can take over the market before this storm comes, then in the future, they can make money while lying down.

Therefore, after Zhang Yiming arrived at Xinfeng Energy, Cong Yu placed more than a dozen shell materials of different processes in front of Zhang Yiming, and took the technician to personally show the shell's shock resistance, flexibility and other hard fingers.

Finally, Zhang Yiming picked out two types of shell materials and asked Cong Yu to treat this shell material at high temperature and high heat, so as to ensure that the fusion of pungent odor and color matching is reduced.

Half a month later, Zhang Yiming will look at the finished product.

Cong Yu agreed.

Fourth, battery.

Whether a mobile phone is easy to use, in addition to appearance, built-in functions, service life, etc., there is another very important indicator, that is battery life.

Especially for tablet phones, the increase in screen and the increase in built-in software will cause a large amount of battery consumption. At the same time, it will also face problems such as black screen and crashes caused by hot battery.

Therefore, a battery with high capacity is a must.

Fortunately, since Deng Haiyang and others took over the development of chips, Jin Sheng has devoted all his energy to the development of lithium batteries. Nowadays, the lithium batteries produced by Hero Electronics Factory are not only the world's first level, but they can definitely rank among the top three in the world.

Especially with a prophet like Zhang Yiming, he gave Jin Sheng a lot of inspiration and technical support. Jin Sheng's research and development can be said to be a great addition to his wings.

"I named this lithium battery 'Little Bomb', with a thickness of 6MM, a length of 95mm, a width of 5mm, and a maximum battery capacity of 1,600am."

Jin Sheng's tone was very excited.

At present, the thinnest battery visible on the world is only 8mm, and its capacity can only reach 1,000am. He has repeatedly tested it and there is no problem with the stability of the battery.

"First, the thickness must be reduced by at least 1-2MM. Second, if the capacity is possible, it will not be increased. This point cannot be increased for the time being. Third, it is the battery life. With the continuous light of the screen, it is guaranteed that the battery can be at least not less than 20% within eight hours. With continuous operation, the battery cannot be less than 20% within four hours. Fourth, improve the charging connector and shorten the charging time."

After seeing Jin Sheng’s operations, Zhang Yiming made four requirements.

Jin Sheng was in a dilemma.

He knew that Zhang Yiming had always been strict, but this time, he felt that Zhang Yiming's strictness was a bit too much.

"Yiming, I know that you have high hopes for TMX222, but what you are talking about is really...it will be really difficult to achieve in the short term."

Jin Sheng felt it was necessary to say it.

He did not deny the future. What Zhang Yiming said would appear, and he even believed that as long as he was given enough time, he could develop it. But now, it is really unrealistic for Zhang Yiming to ask him to solve all these problems within a month.

"Brother Jin, what do you need to do to increase the charging speed?"

"Of course, it is necessary to increase the charging current or charging voltage."

This problem is not too difficult, but the key is the difficulty of implementation.

"If we increase the current and voltage at the same time, will we greatly shorten the charging time?"

"That's natural, but it's difficult to increase the current and voltage to ensure that the instantaneous current will not affect the conduits inside the lithium battery, or even cause combustion or explosion."

"If we perform secondary step-down during high voltage fast charging, will it alleviate the dangers or hidden dangers caused by instantaneous current?"

Jin Sheng was stunned.

Yes, this is feasible, why didn't he expect it at all before?

"Also, while we increase the current, we strengthen the charging cable and charging circuit, can we also avoid the impact of instantaneous current?"

"Yiming, it's amazing, it's amazing."

Jin Sheng looked at Zhang Yiming, really, he has known him for three years, but he is still so shocked by Zhang Yiming that he can't speak.

Zhang Yiming rarely practices, but the ideas and theories he gave always shocked him.

"Now, Brother Jin thinks that the requirements I mentioned before can be realized?"

"Yiming, don't worry, I will definitely not drag you down in the battery!"

Zhang Yiming looked at Jin Sheng and smiled.
Chapter completed!
