Redmi is a technology brand for young people under Xiaomi Group.

The predecessor of edmi is the new product line "Redmi" launched by Xiaomi on July 31, 2013. At 10 a.m. on January 3, 2019, Xiaomi officially announced that it would upgrade the Redmi series to Redmi, an independent sub-brand of Xiaomi’s mobile phone business. On January 10, 2019, Xiaomi held a press conference for the independence of the Redmi brand.

Brand positioning

From the initial positioning, the Redmi series is a product positioning that focuses on volume. Redmi mobile phone (Redmi’s first mobile phone) uses a MediaTek 28 nm quad-core processor and a display with a resolution of 1280×720.

In terms of sales model, we chose to cooperate with China Mobile and QQ Space; and at the price of 799 yuan, this thousand-yuan phone is even more unstoppable. The data at that time was that the first batch of 100,000 units was sold, and more than 9 million users made reservations through QQ space.

In the following years, Redmi has also maintained its cost-effective positioning. However, as the product line of the Redmi series has become increasingly rich, its price space has also continued to expand outwards, falling to 499 yuan (Redmi 2A released in March 2015, special price during Rice Fan Festival);

Going up, it goes as high as 1,499 yuan (Redmi Pro released in July 2016) - such a price positioning , and even overlapped with some mid-range products of the Xiaomi brand to a certain extent.

On January 10, 2019, Xiaomi held a new product launch conference in Beijing, and the new independent brand Redmi was launched. In response to comments from netizens, Lei Jun said: If Xiaomi and Redmi are separated and each develops in different directions, the Xiaomi brand can be made better. Redmi focuses on the ultimate cost-effectiveness and focuses on the e-commerce market. Xiaomi focuses on mid-to-high-end and new retail.

Lei Jun said that English brands all use letter combinations, simple and practical English words, and it is difficult to register trademarks around the world. The name Redmi has been used abroad for many years and is well-known by the public, and Redmi is translated as Redmi , or what Hugo Barra, the former global vice president of Xiaomi, insisted on back then.

Mobile phone business

All Redmi phones (except Redmi Go) use the same system firmware MIUI as Xiaomi series phones, and are deeply customized based on Android. The latest version is MIUI 12.5.

MIUI has three parallel development versions, namely the "stable version" for most users and the "development version" for developers and geeks (during the maintenance cycle, every week except mainland China holidays) Released once every five years) and "Internal Beta" (released every working day during the maintenance cycle).

After the Redmi brand became independent, starting from Redmi Note 7, the system waiting screen when booting was replaced by the MI logo with the Redmi logo, and the "About Phone" interface no longer displays the words "Xiaomi Phone".

Same as the Xiaomi series of mobile phones, all models of the Redmi/Redmi series are equipped with the stable version of MIUI when leaving the factory. Users can download the development version or internal beta version from the MIUI official website for use.

On July 5, 2019, the MIUI team re-adjusted the system development model of each Redmi model. Starting from Redmi 8, it will stop providing development version/internal beta development version firmware for Redmi entry-level models. The maintenance cycle of the development version/internal testing development version of all newly released models will be changed to one year. One year after the product is released, the system firmware of the development version/internal testing development version will no longer be provided.

At the same time, the MIUI development team has begun to strictly control the application process for the stable internal beta version, the weekly updated development version, and the daily updated internal beta development version. All users who want to use the above versions of system firmware must go through Xiaomi Apply through the community APP, and the firmware package can be downloaded only after the application is approved. The MIUI official website no longer publicly provides development version firmware packages.

In addition, although Redmi/Redmi models can root the system, a bootloader (BL lock) is set up in the MIUI system for security reasons. The MIUI download page also provides factory pre-installed software. The application "MiFlash" used when installing firmware and the flash lock are unlocked for users to download and use.

Currently, if users want to root, they need to bind their device to a Xiaomi account and apply on the official website before they can obtain the unlocking tool to unlock it. This mechanism is the same as that of Xiaomi series mobile phones.

All Redmi mobile phones have built-in voice assistant Xiaoai, which enables voice control of smart homes and daily operations. Some models support voice wake-up from the screen. In addition, for Redmi models that support NFC function, the system also has a built-in "Xiaomi Wallet" APP, which can be used to set bus cards, door cards and other functions.
