How are Smartphones Made? The Entire Manufacturing Process Explained

smartphone manufacturing

We have been using mobile phones from quite a while and as of lately we have switched on to smartphones. But on the whole have we ever given a thought as to how these phones are actually made? Right from the conception of the idea to the final outcome of the product, the journey is a steep mountain to climb. Read on if you to understand the entire process.

When a company decides to make a new model, they already have older models so they do not need to start from scratch. All they have to do is fine tune the older model through the feedback of the users or the experts in this field. All the shortcomings of the previous models are taken care of and with new innovation, the technology is injected into the latter model.

Smartphones are manufactured in the following 6 steps:

Making of prototype

The idea is conceived in the board room meeting and then the affirmation is passed to the research and development lab. So they commence with a prototype which is in fact a non working one where the aesthetics is the first thing that has to be considered. This model is passed on to the relevant people so that they may give their opinion to make any changes if required. After the looks of the model are zeroed on, the inside working kit of the handset is worked upon.

The rein of this ride is then handed over to the electronics engineering team and thus it is here the decision is taken on the processor and memory for the handset. The matching display screen and the required battery potential are selected. The front and rear cameras are also not missed out. The device is then armed with the selected components and checked for the working performance. After this, if the decision making team is reasonably satisfied with the working then this handset is sent back to the authorities for their approval.


Most of world’s smartphone manufacturing today is being done in China. 


Software Installation

The software team steps in now to breathe life into the handset. It is basically pre decided on the operating system that is to be loaded into the phone. It is utmost necessary that the hardware that is the part played by the electronics team is compatible for the smooth functioning of the operating system. It is checked here by many experts in their own manner for the system to be working according to the expectation.


The selected design, loaded with hardware and software is then readied for mass production. At this juncture it is often difficult to go back and alter the already approved working prototype.

Testing Phase

Before the production begins, the handset is rigorously tested for quality and other parameters. They are tested in terms of both hardware and software. Various tests like drop test, bend test and water tests are carried out to check its performance.

Mass Production

When the prototype is ready, some components are manufactured in house whereas some specific components are outsourced. Sometimes this information of a new model being launched by the company is leaked to the masses and this could be both helpful or otherwise. Helpful, because it popularizes the ‘to be launched’ handset. And a drawback because this gives a chance for critics to find out faults in the still to be produced models and thus drop down the ratings. The mass production of the quality passed model commences. This could be at the manufacturers own plant or can also be outsourced to other manufacturers also known as original equipment manufacturers (OEM) to be made as per their required quality as well as specs. The smartphones are also assembled in this process. You can learn assembling and disassembling of iPhones and other smartphones by enrolling into cell phone repair training conducted by Prizm Institute.


During mass production, smartphones usually are codenamed to avoid leak of information related to specs and design.



When the handset passes all the tests, then it is sent for packaging. The handset along with accessories and user manual are put into the box ready to be shipped.

The final stage of the entire process is shipment. These packaged phones are then dispatched to retailers across the globe and from these retailers it is you who picks up the handset.

So this is the entire process of making of a smartphone. Please let us know your opinion in the comments below.
