How Are Redmi Phones Made In India? This Factory Tour Will Give You A Glimpse

© Mention India Today How are Redmi phones performing in India? This factory tour will give you an idea

Xiaomi is one of the leading smartphone makers in India, although the company has slipped a notch or two from the top spot in recent months. However, after dropping a notch or two, the company still sells millions of phones in India. Now, have you ever wondered how these phones are made? What is behind the production of these phones? How long does it take to make a smartphone? Well, I had the same questions when I visited DBG India's manufacturing unit in Bawal, Haryana. It is home to a factory where many Xiaomi phones are manufactured. One of them is the recently launched entry-level Redmi A2 Plus.

According to former Xiaomi India head Manu Jain, by 2021, 99 percent of Xiaomi phones will be assembled in the country. In fact, Xiaomi was the first smartphone company to ramp up local production. Today, the company manufactures most of its products in India. Only high-end smartphones like Xiaomi 13 Pro and others are imported from China in full stock. Most comparable Xiaomi and Redmi phones are manufactured, that is, assembled, in India, although most components are sourced from other countries, including China and South Korea.

I recently had the opportunity to visit DBG India's manufacturing facility in Bawal, Haryana, where the Redmi A2, Redmi A2 and A2 Plus series of smartphones are manufactured. The factory has a separate assembly line for the production of Redmi and Xiaomi phones, as DBG also manufactures phones for other brands.

The first step in building a phone is the assembly of printed circuit boards (PCBs), which are assembled on special machines operated by humans. These PCBs are tested multiple times on separate machines to ensure perfect quality. These steps include battery connector, antenna switch, radio frequency (RF) circuit, audio circuit, power management chip, memory chip, etc. Once these parts are placed, the PCBs are accepted with a "good" response and move on to the next manufacturing process. Poorly made or poor quality PCBs are rejected and given a red "reduced" comment. These poorly designed PCBs are sent to the assembly line, and after their defects have been corrected and a clear quality control has been carried out, they are again moved on to the next process.

Then comes the stage of assembling the phone, in this case Redmi A2 Plus-. It should be noted that the DBG factory is mainly engaged in the assembly of phones and not all mobile parts are manufactured in this factory. So now the next step is to assemble all the parts of the phone and create the final product. This area has dedicated staff who add and test every part of the phone. For example, there is an operator who finishes and glues the screen, and on the next conveyor, the accountant checks whether the screen is tightly fixed. Every human check is followed by a machine check.

As for the Redmi A2 Plus, we assume that most of the comparable phones are manufactured using the same process: first, all the parts are assembled, starting with the screen, then the camera, microphone, battery and more. After each component is added, the phone goes through a scanning process to ensure correct placement. I was particularly impressed with the way the camera was made. The phone's camera is in a special case designed to protect it from dust. A visit to the factory told India Today Tech that there are dehumidifiers inside the camera that are constantly running to prevent dust from entering the camera lenses.

Below is the testing process where the screen, camera, battery, charger and all other aspects of the phone are turned on and thoroughly tested. These tests are done manually by workers and then some machine tests are also done. One of the most important tests is the aging test, where the assembled phones are subjected to severe testing. This test tests different parts of the phone at the same time, such as the camera, speaker and screen.

Then comes the most exciting phase: the durability test. There is a separate test area that I find very impressive. There are many tools to check the durability of your Redmi phone. These machines rigorously test each phone by hitting the device from different angles. The devices are dropped from a certain height to ensure their durability.

The phone then undergoes final inspection (manual and mechanical) and is cleared for packaging. In particular, workers pack all packages by hand, even if the packages are already sealed, and not at the factory.

After all, it takes a lot of work, energy and thought to produce a smartphone. For Xiaomi, most phones are assembled in India, except for high-end models like the Xiaomi 13 Pro. These flagship phones still come from China.
