Choosing wearable electronics has become a challenge today due to the sheer number of models produced by the Chinese giant’s ecosystem. Consumers are often lost in acronyms and digital indices, not realizing how the Xiaomi Watch S1 differs from the Redmi Watch 3, and whether to overpay for the Pro version. A mistake in choosing can lead to the purchase of a device with inappropriate functionality or weak autonomy, which will disappoint after a week of use.
In this article, we will take a closer look at the latest line of gadgets so you can make an informed decision. We will analyze the specifications, materials of the case and software features that hide behind marketing names. Understanding these nuances will allow you to buy the device that will perfectly fit into your life rhythm and budget.
The market offers solutions for professional athletes, sleep-trackers, and those who care about just a stylish accessory. The key to choosing is not only the price, but also compatibility with your smartphone operating system. Let's determine which category of devices you want.
The main lines of wearable devices of the company
The first thing a buyer faces is the division of products into Xiaomi, Redmi and Amazfit (the ecosystem’s partner brand), devices under Xiaomi’s core brand are usually positioned as premium, offering metal cases, AMOLED-At the same time, Redmi’s lineup focuses on accessibility, offering basic activity tracking at a affordable price.
Separately, it is worth mentioning the Xiaomi Smart Band series, which was previously known as the Mi Band. This is not exactly a watch, but rather a fitness tracker with a stretched screen, although the latest models (Band 7 Pro, 8 Pro) have already received a full rectangular display and a full-fledged rectangular display. GPS-They occupy a niche between simple wristbands and full-fledged watches, offering a compromise on price and functionality.
- 🔴 Xiaomi Watch – flagship models with premium materials and complex OS or advanced HyperOS.
- 🔵 Redmi Watch – budget smart watch with a good screen and a basic set of functions.
- 🟠 Smart Band – Lightweight fitness trackers with long-term autonomy.
It's important to understand that software can vary significantly: Top models often run on Wear OS or have their own powerful shells, while public sector employees use lightweight versions of firmware. Application compatibility and the ability to install third-party software depend on the line of choice.
⚠️ Note: Not all watches support full notifications with the ability to respond or install messengers.
Selection criteria: screen, GPS and sensors
The central element of any smartwatch is the display. Today, the gold standard is the display. AMOLED-Matrices that provide deep black and high brightness in the sun. LCD-screens that consume more power and have worse viewing angles, which is critical for devices with a constantly on screen (Always On Display).
Presence of built-in GPS-The module is the main watershed between sports and everyday gadgets. If you plan to run or ride a bike without a phone to track the route, you need a model that supports satellite navigation (GNSS, GPS, Without this module, the watch will only be able to show the pace and pulse using the data of the smartphone.
The health sensor suite also varies. Basic models are limited to optical pulse sensor and accelerator. Advanced versions, such as the Xiaomi Watch S3Watch 2 Pro, are additionally equipped with sensors for measuring blood oxygen (SpO2), stress and even body temperature. For professional sports, the accuracy of these measurements and the frequency of the sensors are important.
☑️ Checklist before purchase
When choosing, pay attention to the refresh rate of the screen. For smooth interface animation and comfortable scrolling lists, a frequency of 60 Hz is desirable. Less productive models can operate at 30 Hz, which visually feels like a twitch of the interface, this is especially noticeable when using complex second hand dials.
Comparison of popular models: Characteristics table
To make the decision easier, we have brought the key parameters of the models in a single table, and here are the devices that are most popular at the moment and represent different price segments.
| Model | Screen type | Autonomy | Case material | |
|---|---|---|---|---|
| Xiaomi Watch 2 Pro | AMOLED | Yes. | 5 days | Nerzh. |
| Xiaomi Watch S3 | AMOLED | Yes. | 12 days | aluminum |
| Redmi Watch 4 | AMOLED | Yes. | 20 days | aluminum |
| Smart Band 8 Pro | AMOLED | Yes. | 14 days | Plastic. |
As the comparison shows, even in the mid-range segment presented by Redmi Watch 4, manufacturers are beginning to adopt built-in GPS, which was previously the prerogative of expensive devices. However, the materials of the case remain an important differentiator: plastic is easier but faster to scratch, while aluminum and steel give the device solidity and durability.
Smart watches with a full OS consume more charge faster due to background processes, while proprietary Xiaomi systems are optimized to work for weeks without recharging. The choice here depends on what is more important to you: the functionality of the smartphone on the wrist or rare charging.
Why is the autonomy less than the claimed?
Operating Systems: Wear OS vs HyperOS
The internal kitchen of the watch defines its capabilities: Xiaomi Watch 2 models run on Google’s Wear OS, which gives access to the Google Play store, the ability to install maps, music and full-fledged apps, but this openness requires more powerful hardware and frequent recharging, and limits compatibility mainly with Android smartphones.
Most other models use the branded HyperOS shell (formerly MIUI for Watch), a lightweight, fast system that works great with both Android and iOS (iPhone), which provides smooth interface and high energy efficiency, but does not allow you to install third-party applications from stores. All functionality is installed by the manufacturer and updated only through firmware.
- 🚀 Wear OS — For those who need apps, maps and phone independence.
- 🔋 HyperOS – for those who appreciate autonomy, simplicity and work with the iPhone.
- ⚙️ Compatibility – Check the Android version (usually 6.0)+) or iOS (12.0)+) pre-purchase.
iPhone users should be especially careful: the functionality of the watch on Wear OS on iOS is extremely limited or absent, owners of Apple smartphones are advised to choose models based on HyperOS, which are synchronized through the Mi Fitness app (formerly Zepp Life), which will provide full access to dial settings and data analysis.
⚠️ Note: When switching from Android to iOS (or vice versa), it may take a full reset of the clock to re-bind it. Training data may not sync across different ecosystems without manual exporting.
💡
Tip: If you plan to upgrade to an iPhone in the future, it’s best to choose a watch on Xiaomi’s own OS (HyperOS) right away to avoid compatibility issues in the future.
Design and interchangeable straps
The look of the gadget is no less important than the stuffing. Xiaomi has implemented a Quick Release system that allows you to change the style of the device in seconds without tools, which turns the watch from a sports accessory into an elegant element of a business fire or everyday wear.
The Xiaomi Watch S3 series, which offers a “one thousand changes” concept, is particularly noteworthy. With the unique bezel (external ring) mounting mechanism, the user can change not only the strap, but also the decorative ring around the screen. When changing the ring, the watch automatically recognizes the new design and changes the dial in the appropriate style.
The materials of the execution also affect the tactile sensation and weight on the arm. Aluminum alloys are lightweight and do not cause allergies, but can oxidize when actively in contact with sweat. Stainless steel is heavier but looks more expensive and durable. Plastic is the lightest option, ideal for sleep and sports, but it can store static electricity and smell.
💡
The ability to quickly change straps and rings allows you to have one gadget for the gym, office and evening exit, saving money on the purchase of several devices.
Fitness functions and health monitoring
For many users, the watch becomes a personal trainer, with hundreds of supported sports modes, but usually no more than ten in use, and more important is the quality of tracking: the availability of automatic determination of activity type (running, walking, rowing) and calorie counting accuracy.
Health monitoring goes beyond just counting steps: Current models track sleep phases (REM, deep, light), blood oxygen levels, and even breathing exercises. Some flagships have gained support for body composition measurements, although the accuracy of such wrist measurements is still a matter of debate among experts.
For professional athletes, it is important to create interval training and adjust target heart rates. Mi Fitness allows you to analyze load and recovery schedules in detail. Integration with popular services like Strava or Apple Health (through third-party bridges) expands the analysis capabilities.
- 💓 Pulseometry – continuous or on request, with notification of exceeding the norm.
- 😴 Sleep analysis – rest quality assessment and recommendations for improvement.
- 🩸 SpO2 — Oxygen measurements relevant for highlands and health control.
It should be noted that no smart watch is a medical device, and its indications are informative, and for serious health problems, you should use specialized medical equipment certified by the relevant authorities.
