Every request put forward by Zhang Chen subverted Jiao Kai's understanding of mobile phones, especially the cancellation of mobile phone keyboards, which made Jiao Kai unacceptable, without a keyboard, can it still be called a mobile phone?

However, following Zhang Chen for so many years, Jiao Kai has developed a habit, that is, what Zhang Chen says and what he does, because Zhang Chen has proven countless times that his seemingly counterintuitive ideas and decisions are correct in the end, so even if some people in the team have raised doubts, and even some people feel that there is no point in developing such a mobile phone, Jiao Kai still supports Zhang Chen without hesitation.

Fortunately, Jiao Kai's friend who had worked in the Android company was very interested in developing this new smartphone, and he also gave Jiao Kai great confidence, so he was very resolute in the doubts of others in the development team, and he either obeyed or left.

These people in the team are all talents poached from foreign companies with high salaries, and it is impossible for anyone to retreat at this time, so everyone had to carry out development and research according to the requirements of Jiao Kai, and successfully produced the prototype of the first smart phone.

When he first saw the front of the prototype, Zhang Chen was happy, this prototype is very similar to the smartphone in his mind, the 4-inch screen almost occupies the entire fuselage, and there is only one button left on the front, but when he took a closer look, he found that there seemed to be a bit of a problem, the thickness of this prototype is almost the same as the thickness of a laptop, and it is definitely a veritable brick.

Jiao Kai reported to Zhang Chen on the development of the first stage, according to Zhang Chen's original concept, the prototype of this smart phone can be installed like a computer, run and delete various software programs, but in order to better realize these functions, some of the hardware in the prototype uses notebook accessories, because Zhang Chen requires the size of the mobile phone to be within 4 inches, so it can only increase the thickness of the fuselage.

Jiao Kai told Zhang Chen that he had contacted the manufacturer of the mobile phone hardware, and the other party was also developing a mobile phone processor with high performance and small size and other mobile phone hardware, and after the new hardware was released, it should be possible to greatly reduce the thickness of the fuselage.

Zhang Chen listened to Jiao Kai's introduction, while playing with the prototype, the mobile phone uses the open source system of the Android company, which has installed several newly developed programs and small games, Zhang Chen tried it, although it still needs to be improved, but at least the general direction is not wrong.

After Jiao Kai's report, Zhang Chen was still fiddling with his mobile phone over and over again, and after a long time, he suddenly raised his head and asked, "How long can this prototype standby?" ”

"Normal use can be about a week standby, heavy use can be used for up to three days, this prototype uses ordinary liquid lithium batteries, if replaced with a new lithium-ion polymer battery, the volume and weight can be reduced by about one-fifth, but the manufacturing cost will be increased by one-third."

Zhang Chen checked the slightly heavy prototype in his hand, pondered for a moment, and then handed the prototype to Jiao Kai and said, "What does the battery look like inside, remove it and let me see." ”

Jiao Kai nodded, took the prototype, pushed open the back cover like a normal mobile phone, and then removed a battery module that was three times the thickness of an ordinary mobile phone battery.

Jiao Kai took the battery and explained helplessly: "Because it was replaced with a large screen, the power consumption speed of this prototype is much faster than that of ordinary small-screen mobile phones, if you still use ordinary capacity batteries, you can only standby for half a day at most under normal use, so you can only increase the battery capacity." ”

Zhang Chen thought for a while and said, "I think there should be two changes in the battery. ”

"Which two?" Jiao Kai took the notebook next to him, intending to write down Zhang Chen's opinions.

"First of all, I don't think the phone needs to be on standby for so long, if you use it normally, two days is enough, and if you use it heavily, you can guarantee a charge a day."

Jiao Kai originally planned to write down Zhang Chen's words, but after listening to them, he didn't start writing, but said suspiciously: "Standby for a day or two?" Will this work? Now many mobile phones are claimed to be on standby for a month, and even some say that they can be on standby for three months, but our mobile phones can only be on standby for one or two days, will the people recognize it? ”

Zhang Chen guessed that Jiao Kai would question, and he explained unhurriedly: "Indeed, everyone's habit now is that the longer the standby time of the mobile phone, the better, but to be honest, in fact, the mobile phone standby time is too long and there is no great use, it is nothing more than that you can charge it a few times less, and you can use it for a few more days when you go out, but people have to sleep every day, use the mobile phone during the day, and charge it when you sleep at night, and one charge a day can fully meet people's daily use." ”

Zhang Chen paused a little when he said this, then glanced at Jiao Kai's expression, and found that he still didn't seem to understand, so he continued to explain: "Let's put it this way, a laptop can be used for a few hours at most, if your mobile phone can achieve most of the functions on the computer, and it can also standby all day, will you still be troublesome to charge it once a day?" ”

Jiao Kai thought about it for a while and felt that what Zhang Chen said did make some sense, but he was still not sure whether the user could accept that the mobile phone would need to be charged once in a day or two, but with the inertial thinking that Zhang Chen said that everything was definitely right, he still wrote this down and planned to go back and make changes to the prototype.

After Jiao Kai finished recording, Zhang Chen threw the battery in his hand aside, then picked up the prototype on the table and said: "The second point, I think it is completely possible to design the mobile phone battery to be inseparable, so as to reduce the shell and some internal structures of the battery, and also virtually reduce the thickness and weight of the mobile phone." ”

"A non-detachable battery? What about when you change the battery? Some of Zhang Chen's views are always so incredible in Jiao Kai's opinion.

"Replace the battery? Why change the battery! Think about it carefully, do you usually use to plug your phone directly into the power source to charge, or do you charge the battery first and then change the battery when it runs out? ”

Jiao Kai frowned and thought about it carefully, although his mobile phone has two batteries, he usually only charges his mobile phone, and only replaces the battery when the mobile phone is out of power and can't wait to charge, but this situation is very rare.

"Is it really okay to do what you say?"

Zhang Chen nodded heavily: "Sure, you just design according to what I say, it's absolutely no problem, by the way, I have a new idea about your prototype!" (To be continued.) )
