The Chinese giant’s wearable electronics market has undergone a huge transformation in recent years, from a simple fitness tracker to a full-fledged ecosystem of smart gadgets. Today, a potential buyer faces a difficult dilemma: the range of devices under the Xiaomi, Redmi and Amazfit brands is so extensive that it is extremely difficult to understand it without preparation, and the choice depends on many factors, including budget, smartphone operating system and priorities, whether it is professional sports or health control.
In this article, we will take a detailed look at the current 2026 lineup so you can understand which watches you should buy, and we will analyze the specifications, autonomy and functionality of various versions of HyperOS firmware for wearable devices.
Don’t rely on marketing slogans alone, as real performance is often hidden in the details of sensors and data processing algorithms. A properly selected device will be a reliable assistant, whereas a mistaken purchase can lead to frustration due to unjustified expectations.
Ecosystem Evolution: Mi Band vs. Watch
The fundamental difference between the Mi Band and Xiaomi Watch series is not only in price but also in the software architecture. Band trackers traditionally run on the proprietary RTOS (Real-Time Operating System), which provides phenomenal energy efficiency but limits the ability to install third-party applications. At the same time, full-fledged watches are often based on Wear OS or deeply modified versions of Android, offering a wide range of functionality but requiring more frequent recharging.
If you’re looking for a device that’s solely for activity monitoring and notifications, the Mi Smart Band 10 flagship tracker is the best choice. Its 60Hz AMOLED screen provides interface smoothness comparable to smart watches, while keeping the body weightless. For users who are critical to long-term work without recharging, this is a crucial factor.
However, if you need full navigation, the ability to respond to messages from the keyboard and install cards, then you should pay attention to the Xiaomi Watch S series. These devices support a full Bluetooth call and have a built-in NFC module for contactless payment, which brings them into the category of independent gadgets.
⚠️ Note: When buying, make sure the firmware version is relevant to your region. Global Version has a pre-installed multilingual interface and support for Google services, while Chinese versions have a pre-installed multilingual interface and support for Google services (CN Version may require complex region manipulation in the Zepp Life or Mi Fitness app.
Choosing between form factors also affects strap compatibility and wear style: The classic round watch dials are better matched with business style, while rectangular or oval tracker shapes remain a sporty accessory.
Budget segment: Redmi and the initial Mi Band models
The entry threshold for Xiaomi’s wearable electronics is traditionally low, making these gadgets accessible to a wide audience. The Redmi Watch lineup and the basic Mi Band versions offer a great balance between cost and functionality, covering 90% of the needs of the average user. Here you get an accurate pulsemeter, sleep monitoring and basic sports modes.
Models like the Redmi Watch 5 Active feature large displays with a resolution of 320x380 pixels, which ensures excellent readability of text even in bright sunlight. Despite the plastic case, the device passes waterproof tests according to the 5 ATM standard, allowing you to swim in the pool without risking damage to electronics.
It is important to note that the budget segment often uses a simplified version of health analysis algorithms, for example, measuring blood oxygen (SpO2) can take longer and have a greater margin of error than flagships, but this data is quite informative for tracking dynamics over months.
- 🔋 Autonomy up to 14 days in smart recognition mode.
- 🏊♂️ More than 100 sports modes with automatic activity detection.
- 📱 Notifications from messengers with the possibility of a quick response (templates).
- 💰 The optimal ratio of price and quality of the body.
When choosing a budget model, consider the material of the strap, since cheap versions often use low-quality silicone, which can cause irritation when worn for long periods of time.
💡
To extend the life of the lithium battery in budget models, turn off the function of “Constant monitoring of pressure”, leaving only periodic measurements on schedule.
Flagship solutions: Xiaomi Watch S and Pro series
The top-end market segment is represented by the Xiaomi Watch S4 and Watch S3 series, which are marketed as premium devices, where manufacturers are betting on materials such as sapphire glass, titanium body and ceramic back cover, which not only improve aesthetics, but also increase wear resistance in extreme conditions.
A key feature of the flagships is the dual-frequency GPS (L1+L5), which provides high positioning accuracy even in dense urban areas or dense forests. For runners and cyclists, this is a critical parameter that allows you to build accurate tracks without cutting corners and losing signal.
The HyperOS software shell on these devices works as smoothly as possible, supporting animations at 60 FPS. The user gets access to the application store, where you can download maps, voice recorder, calculator and even simplified versions of navigators. Integration with a smart home allows you to control lights and sockets right from the wrist.
| Characteristics | Xiaomi Watch S4 | Xiaomi Watch S3 | Redmi Watch 5 |
|---|---|---|---|
| Case material | Stainless steel | Aluminum alloy | Polycarbonate |
| Display. | AMOLED, 1.43" | AMOLED, 1.39" | AMOLED, 1.96" |
| GPS | Bi-band | Single-band | Built-in (basic) |
| Battery | 15 days | 12 days | 10 days |
Flagship models also offer advanced health metrics, such as heart rate variability (HRV) analysis and real-time stress assessments, which are processed by a local neuroprocessor, which improves measurement accuracy and reduces smartphone load.
💡
Flagship watches make sense if you are actively engaged in outdoor sports (need accurate GPS) or you are interested in premium aesthetics and materials.
Specialized devices: Sport and Lite versions
Specialty lines, such as the Xiaomi Smart Band 8 Pro or Amazfit Bip series, often occupy a niche between trackers and full-fledged watches, offering a larger screen without significantly increasing the thickness of the case.
The sports version often implements more advanced algorithms for specific disciplines: running, swimming, triathlon. For example, the swimming mode can recognize swimming style (crop, breaststroke, butterfly) and count strokes, which is not available in the basic models. The 6-axis acceleration sensor is calibrated with increased accuracy here.
Lite versions, by contrast, are designed to be minimalist and as light as possible, often lacking built-in features. GPS-This allows you to make the body thin and almost weightless, which is especially important for sleeping and wearing around the clock.
- 🏃♂️ Specialized metrics for runners (VO2 Max, recovery time).
- 🏊♀️ Improved water protection and swimming algorithms.
- 🎨 Replacement frameless structures for customization.
- ⚖️ Ultralight weight less than 25 grams.
When choosing a specialized model, it is important to understand what kind of sport it is sharpened for. Universal watches may not have the specific features required by professionals in a narrow field, such as echo-heights for mountaineering or detailed telemetry for cycling.
⚠️ Warning: Specialized sports watches can consume battery power faster when used actively GPS. Always bring a charger for marathons or long bike rides.
Compatibility: Android vs iOS
Compatibility remains one of the most pressing issues when choosing wearable electronics. Xiaomi devices work perfectly with Android smartphones, providing full access to all features including quick responses, music management and contact synchronization. Mi Fitness (formerly Zepp Life) app works stably and offers deep customization.
With iPhone owners, the situation is a little more complicated, because of the limitations of the iOS operating system, the functionality of the watch can be reduced, for example, you can not answer an incoming call or message directly from the watch, but only see the notification, and there may be problems with the background synchronization of health data in the Apple Health app.
For iOS users, it is critical to use current versions of apps from the App Store, as older versions may not support new Bluetooth 5.3 communication protocols. It is also recommended not to remove the app from the smartphone memory to ensure constant communication with the watch.
How to improve communication with iPhone?
If you’re planning to change your smartphone platform in the future, consider that your workout and health history is tied to your Mi Account, making it easy to transfer data to your new phone regardless of the operating system.
What to look for when buying in 2026
Buying a smartwatch in 2026 requires attention to details that were previously considered secondary. First of all, pay attention to support for new wireless standards such as Wi-Fi and NFC for your region. Not all global versions have working NFC for payment in CIS countries, this must be checked separately.
The second important aspect is the availability of service and spare parts. Popular models like the Mi Band always have a lot of accessories, while rare watch modifications can be left without straps or protective glasses a year after the release.
Xiaomi guarantees major firmware updates for 2-3 years for flagship models. Budget devices can only receive security patches, which is worth considering if you buy a gadget for the long term.
☑️ Checklist before purchase
The final choice should be based on a sober assessment of your needs, there is no point in overpaying for a titanium case if the watch is used only to count steps and notify calls, and vice versa, saving on sensors can negate the benefits of sports.
