Many people are changing Apple original batteries, then which manufacturers are produced by the original battery?

Some people say that Huawei mobile phone has no technical content, because Huawei mobile phone parts are purchased, so Huawei mobile phone is an assembled mobile phone. If this logic is followed, Apple phones are also assembled because the parts of Apple phones are also purchased.

If you look at Huawei and Apple this, then this is a bit shallow. As we all know, Apple and Huawei have their own mobile phone chips, but these two mobile phone manufacturers have no production capacity, as long as designing the ability of chips. Even so, no one will think that the A series of chips, the unicorn chip is not apple, Huawei.

Through the class ratio of the chip, we can draw a conclusion, that is: Apple’s original battery is Apple, not a vendor’s proposal. In other words, Apple’s battery and chip are the same, Apple is responsible for designing, battery manufacturers are responsible for substitute, and produced batteries are collectively referred to as ‘Apple Battery’. So what kind of battery manufacturers gave Apple’s workshop?

The A series of chips are unified by Apple, because of the capacity, Apple will find Taiwan Power, Samsung Operation. The A-series chips produced by these two companies can be used normally, and unified standards.

Like A Series chips, Apple has also developed Apple batteries, unified implementation of GB / T 18287-2000 standard. Therefore, the battery produced by Apple’s foundry is not essential, and it can be considered an Apple battery.

I have to say that Apple has mastered the core technology, through the battery design, putting the commercial use of the battery in hand. The battery is not difficult, and many people can be found worldwide. Because of this, Apple’s battery has become a business order that many battery manufacturers strive to be afraid, and this is the bottom gas of Apple’s heavy mobile phone market.

Apple mobile phone shipments have a vision, and 2 in 2021 will not be a problem. Even in 5 years ago, Apple’s ship’s shipments have exceeded 100 million sets. As the average unit price, the company’s largest mobile phone manufacturers, Apple’s partial profits are also the most expensive. Because of this, there are many battery manufacturers who are willing to produce batteries for Apple. Early, Sony, Samsung, Le Jinhua, Dongguan New Energy is Apple Mobile Optional Battery.

First, Sony is the masterpiece of the manufacturing industry, and the Sony mobile phone is also the existence of Sony mobile phone in the mobile phone market. However, Sony has strong strength in parts processing, cameras, sensors, and precision machining, so Sony is also a generous thing to give Apple mobile phone.

Second, the strength of Samsung Electronics does not have to be said, the only company in the world can produce mobile phones independently. From chips, motherboards, screens, sensors, cameras, batteries, etc., Samsung Electronics can be produced. Therefore, Samsung gives the Apple mobile phone, which is an extremely easy thing.

Third, in 2003, LG invested in China in my country. This company is engaged in the production and development and production of batteries, and the production of cutting-edge electronic materials. LG has far-reaching influence in the world, and Lejin chemistry can produce batteries to Apple mobile phones. This is also a more easy thing.

Fourth, Dongguan New Energy is a company dedicated to battery cells, packages, and system integration. In the field of battery, Dongguan’s new energy has great influence.

It is not difficult to see that these four companies are leaders in the battery. In particular, Lejin Chemistry and New Energy in Dongguan. These two companies are professional research and development, manufacturers who produce batteries. The so-called: Sheriff has a success, the operation is specialized, and it is justified in these two companies.

With the increase in the shipments of Apple mobile phones, Apple’s battery generations have become more and more, such as Shunda, New World, Germany, and Xinwangda and other manufacturers have successively become Apple mobile phone.

However, these manufacturers and Samsung, Sony, and Lejin chemistry have essential differences, because these three companies can produce battery cells independently, while Shunda, Germany, Xinwangda, etc. can only purchase battery, packaged, package Can produce an Apple mobile phone battery.

Through a series of competition, the batteries produced by Germany and Xinwangda are more in line with the needs of Apple. Since then, Apple mobile phone batteries are mainly produced by these two companies.

First, Desai Battery was established in 1983. After more than 30 years of development, Desai batteries have become a battery that sets a lithium battery, zinc air battery, lithium polymer battery, fuel cell, and other kinds of batteries, battery materials. supplier. It is not exaggerated, and the battery that can be seen on the market can be produced and can be completed independently.

Second, Xinwangda was established in 1997 and is a leading lithium-ion battery module solution and product provider. Although Xinwang’s business has no extensive business, Xinwangda focuses on a horse in a lithium-ion battery, is a strong battery supplier in China, and a global battery.

Whether it is Lejin Chemistry, Dongguan New Energy, or Germany, Xinwang, facing Apple, they can’t be alone. Why is this so? Because Apple is not afraid of them, these battery manufacturers rely on Apple’s orders.

It can be seen that only master core competitiveness and core productivity can be able to overport. What is the core competitiveness? Such as Taiwan Power, Samsung’s chip solution strength, only these two mobile phone chips can be produced worldwide. What is the core productivity? A large-scale enterprise such as Apple can design the battery module to give this design to any battery manufacturer can workene.

So TSMC, Samsung is a company that masters core competitiveness. Strong Apple does not dare to despise them. Work hard, domestic electronics manufacturers, the road you have to go is still far away.

How to solve and eliminate the obstacles faced by the team?

· Foreword ·


After years of work, I have done a lot of different projects in different companies. These companies include tens of thousands of people, such as Huawei, including small private enterprises having 10 people, and work in government institutions . In these different enterprises, they all form some experience of project management, and they still have a success, so they still have more confident.

However, with time, I gradually found a problem, that is, I always feel that my project management knowledge is not very systematic. Every time I have a project management knowledge, I will only pass only, and I have not brought it to the face. And deeper levels, therefore actively conducted PMP learning.

The following is that after I study PMP in the system, combined with the original actual work, some summary and sentiments sublimated, I hope to give some small help to the needs of the friends.

·Background of the project·

Background of the Project

I have encountered a project when I work in a IVD company, and I received leadership arrangements.Responsible for research and development of a fully automated chemical instrument. The instrument is mainly measuring liver function, renal, blood sugar, blood lipids. The instrument needs to operate 7 * 24 to meet the actual requirements.

During the research and development, the product engineering sample has been developed, but during the trial operation, it is found that it will stop in operation for 1 hour. This issue will naturally have a big impact on the product, and the company’s leaders are also very concerned.

So the organization of the Organization of R & D team initiated a meeting, including colleagues in various major colleagues such as machinery, hardware, software, and crafts. The result after discussion is:

The machine’s colleague said: "There is no problem with the structural parts I design";

Hardware colleagues said: "There is no problem in my board";

Software colleagues said: "We checked the code, no such problem";

The colleague of the process said: "There is no problem in the assembly process."

After discussing a circle,Discover all parties deniny their own problems. Since everyone has no problem, then the instrument "see ghost", you will not run. The entire project is turned in a pause.



In this case, I use past experience and introduce it.First question responsibility system. Since I am a software technology, I finally delivered to the customer must be a software that can be run, so the person in charge first confirmed is a software team.

The software team is the first responsible person. If the software team can prove that the problem is not a software problem, it is suspected to be hardware, mechanical or process, and then contact the hardware, machinery or process team, further problem positioning.

Although I introduced the first question responsibility system, I actually act as the ultimate leader, or with the software team to participate in all positioning activities. In this process, I use my software expert’s ability and gradually discover a lot of software, and Solved one by one.

Among them, there is a more interesting solution to the problem: the same problem may come from a number of different reasons, and be sure to find one solution.

For example, this operation is 1 hour, it is 2 ~ 3, and after 1, it is found that the problem of running 1 hour will still exist, or may run 2 hours. So don’t doubt, the previous problem may have been solved, and now there is a new reason, you can continue to solve it, don’t take yourself in, and clarify your own ideas.

Finally, after a hard software problem, it is found that the instrument still has 2 hours of downtime, and sometimes it will be down for 1 hour, and there may be a deadlock.

At this time, it is necessary to make reasonable conjecture, is it possible to be a hardware FPGA problem, I will need to use it.Communication skillsNS. I immediately found the engineers of hardware FPGA, of course, you are welcome, because the previous hardware has already firmed "hardware no problem", if only doubts, let them solve the problem, I am afraid, I can’t accept it, this is the test.Project managerThe time!

I found that the engineer of hardware FPGA was: "Brothers, can help support this issue, the software brothers have no idea", hardware FPGA engineers have heard that they are helpless, naturally willful. If you say: "Brothers, you may have problems" So the communication soft skill here is also very important.

When finding a hardware FPGA engineer to help position the problem,As a coordinator, guiding software and hardware colleagues work together towards a big solution direction.Note: The software and hardware colleagues usually focus on their own technology, very much attention to overall solutions. Therefore, under my guidance, look at the software code and process, while licking the FPGA code, ultimately, our hardware FPGA’s colleagues, found that there is a problem with an interrupted trigger time in his code, follow his own There is no problem with the design, but once and the software, there will be an error when running together!

Finally, after the hardware FPGA’s colleague modifies the code, this bug finally solved! As a leader of the project, I finally loose!

When I solve this problem, I didn’t learn PMP, but as the old will succeed in the Sand, I solved the problem with my feelings and experience. But why can I solve this problem?

After learning PMP, there was a matter, just as described above, that is, my solution, now summarizing it:

Meeting -> (First Question Responsibility System) Team Articles -> Expert Judgment -> Communication Equity -> Guidance Conference.

Through these 5 steps, I think you can also become a helping team to solve the challenge!
