What are Xiaomi phones: Expert analysis of brand and technology

In today’s mobile world, it’s hard to find someone who hasn’t heard the name Xiaomi. The Chinese giant has gone from being a small start-up to one of the world’s largest electronics manufacturers, supplanting many of the world’s historical market leaders. When we talk about what Xiaomi phones are, we don’t just mean phone calls, but complex multimedia centers with cutting-edge hardware and unique software. The brand’s popularity stems from aggressive pricing and a willingness to innovate even in the budget segment.

But for the untrained user, the company’s assortment can seem like a confusing maze: Models come in the dozens, titles change from series to series, and regional differences add to the confusion. Understanding the brand structure, the differences between the Redmi, POCO, and Mi (now Xiaomi) lines, is a key buying factor. It’s that knowledge that will help you choose the device that perfectly suits your needs, whether it’s mobile photography, gaming, or just a reliable workhorse.

In this article, we will take a look at the architecture of the brand, the features of the operating system, and give you an idea of what to look for when choosing, why some models are cheap and others claim to be premium flagships, understand the intricacies of the MIUI shell and the new HyperOS, and discuss whether to buy these devices in the current market conditions.

Brand philosophy and company history

Founded in 2010 by Lei Jun, the company had an ambitious goal: to make technology available to everyone, Xiaomi’s philosophy was to minimize hardware revenue (less than 5%) and monetize through software services and the ecosystem, an approach that allowed the company to offer top-end devices at a price often 60-70% of that of competitors with similar hardware.

A key element of success has been the smart home concept and ecosystem, with the smartphone as the central control panel, where you can control lamps, robot vacuum cleaners, air purifiers and even electric toothbrushes through a single app, creating a brand-like “stick” effect: once you buy one cheap gadget, you often return for a second and third to merge them into a single IoT (Internet of Things) network.

Crucially, the company is not just copying solutions, but often pioneering niches, pioneering 120W charging, allowing the phone to be fully charged in 15-20 minutes, and is actively experimenting with form factors, including foldable smartphones and transparent case devices, demonstrating engineering capabilities.

Model range structure: Redmi, POCO and Xiaomi

Understanding the hierarchy of brands within the holding is the first step to making the right choice: For a long time there was a division into Mi and Redmi lines, but in 2021 the company undertook a restructuring. Now flagship devices are released simply under the brand Xiaomi, and the sub-brand Redmi is responsible for the mass market. POCO — Originally a series within Redmi, it has grown into a standalone brand focused on online sales and enthusiasts.

Redmi's lineup is divided into several series. The Redmi A and C budget series offers basic functionality for simple tasks. The Redmi Note series is a "middle ground" offering excellent screens and cameras at an affordable price. Redmi's top models, such as the K-series (in China) or Pro versions, often get flagship-level processors, second only to the main flagships with body materials and the presence of telephoto lenses.

The POCO brand is positioned as a choice for gamers and those who care about maximum performance for every dollar spent. The POCO F and X series are often based on the platforms of previous Redmi flagships, but in a simpler body. This allows you to reduce the price while maintaining high speed. The POCO M series is focused on the budget segment with a focus on autonomy.

Operating system: MIUI and transition to HyperOS

One of the main features of Xiaomi phones is their software shell. For a long time, the standard was MIUI, a deep modification of Android that completely changed the visual style and functionality of the system. MIUI is known for its rich set of settings, design themes and second space. However, over time, the shell has become criticized for redundancy, the presence of advertising in free applications and optimization.

In response to user requests and to unify the operation of all devices in the ecosystem (from watches to cars), the company has begun implementing HyperOS. It is a new operating system based on the Linux kernel and Android, but with rewritten code for better performance. The transition to HyperOS marks a shift from the heavyweight MIUI in favor of lightness, speed and deep integration with the smart home.

Users are pointing out that new systems are becoming more responsive and animations are becoming smoother. An important aspect is the ability to fine-tune. You can change almost any interface element, from icons to notification curtain behavior. For advanced users, the ability to unlock the bootloader allows you to install custom firmware, although in recent versions of MIUI and HyperOS this process has been significantly complicated for security purposes.

⚠️ Note: In some regions on shell devices MIUI System advertising may be present, and can be disabled manually in each application settings or via the hidden msa menu, but the process may take time and care.

Technical specifications and hardware platform

Xiaomi phones are famous for their ability to pack powerful hardware into an affordable package. The company has been actively cooperating with Qualcomm and MediaTek, often gaining access to new processors before others. The flagship models of the Xiaomi 13 and 14 series use the latest Snapdragon 8 Gen chips, providing the highest performance in games and heavy tasks.

The screens deserve special attention. The brand was one of the first to start mass use. AMOLED-And these are high refresh rate arrays (120 Hz), even in the middle segment, which provide a juicy color reproduction and smooth scrolling of the tape. LTPO, dynamically change the refresh rate from 1 Hz to 120 Hz to save energy.

Here is a comparison of the main series by key parameters:

The battery and charging are an important element of hardware, with 5,000 mAh standard capacity, and support for fast charging from 33 watts to 120 watts and up is even present in mid-range models, which allows you to forget about power banks and charge the device during a short break.

Camera and collaboration with Leica

For a long time, the cameras in Xiaomi phones were considered a good but not a great solution, and that changed dramatically with the start of the partnership with the legendary German company Leica. Since the Xiaomi 12S Ultra series, engineers have focused not on the race of megapixels, but on the quality of optics, sensor size and color reproduction.

Using Sony’s 1-inch IMX989 and LYT-900 arrays, the natural background blur (bokeh) without software algorithms was previously the domain of SLR cameras. The software processing now offers two styles: “Leica Vibrant” (saturated colors) and “Leica Authentic” (natural tones and contrasts), giving the user creative control over the image.

💡

For the best photos at night, use a tripod and switch to manual or Night mode, increasing shutter speed. Don't rely solely on automatic mode in very low light.

In the mid-range (Redmi Note) cameras are also progressing, with the introduction of 200MP sensors allowing for detailed snapshots with framing capability without loss of quality, but it’s worth remembering that budget models often lack optical stabilization (OIS), which can affect video quality and nighttime shooting.

Advantages and disadvantages of ecosystems

Buying a Xiaomi phone gives you access to a vast world of devices. The Mi Band and Watch smartwatches sync perfectly with your smartphone, offering detailed sleep and workout analysis. The Roborock or Xiaomi Vacuum series of robot vacuum cleaners build room maps and are controlled through the same app as the phone. This creates a single digital space where all devices “talk” to each other.

But the system has its downsides, and the main one is the fragmentation of updates. If flagships receive Android updates for 3-4 years, Redmi’s budget models can stay on the old version of the OS forever.

⚠️ Note: When buying a device, make sure that your mobile carrier’s frequencies are supported (especially Band 7 and Band 20 in Europe and CIS (CN) The band may not have a Band 20, which will lead to poor reception in buildings and outside the city.

Another aspect is privacy. Like many tech companies, Xiaomi collects telemetry data to improve services. Users concerned about privacy can set up privacy settings in the Settings menu → Passwords and Security → Privacy by disabling the collection of unnecessary statistics and advertising.
