Sport is often a reliable stress test for evaluating enthusiasm around new technologies. In controlled environments such as laboratories or office conditions, most modern devices perform as expected, but real-world use quickly exposes engineering trade-offs. Testing wearable electronics in more demanding conditions provides a more realistic assessment framework. These conditions include vibration from uneven or rough terrain, changing weather, higher battery consumption, and the need for immediate navigation and continuous connectivity. Together, they place significantly greater demands on smart devices. The Xiaomi Watch 5 represents an attempt to combine premium materials, the full version of Google’s Wear OS operating system, Xiaomi’s HyperOS ecosystem layer, and an EMG-based control system. However, the device’s capabilities are most fully realized not in isolation, but when integrated into a broader ecosystem of connected devices and services.

Market positioning and price

For this review, the smartwatch was used in combination with the Redmi Note 15 Pro smartphone and Mijia Smart Audio Glasses open-style smart glasses. This setup makes it possible to evaluate the ecosystem concept under real-world conditions, where each device complements the others rather than functioning in isolation.

Xiaomi Watch 5

For a long time, the brand was primarily associated with affordable fitness trackers and entry-level smartwatches that prioritized long battery life over full-featured operating systems. The positioning strategy of the Xiaomi Watch 5 represents a clear shift in this approach, reflecting the company’s intent to enter the premium smartwatch segment and compete more directly with flagship devices from Apple, Samsung, and Huawei. For context, I currently use the Apple Watch Ultra 2, and previously used the Apple Watch Series 3, so the comparison is not intended as a direct competition with Garmin-class devices. My experience within the Apple ecosystem will occasionally be referenced throughout the review. Interestingly, when friends saw the Xiaomi Watch 5 on my wrist, they commented that it looks more premium and asked whether I had finally switched to a more traditional watch format.

For the European market, at the time of writing, it is priced at around 300 euros. This pricing is notably aggressive for a device based on the Wear OS platform and featuring a stainless-steel case with sapphire glass. Competing products with similar materials are typically positioned in a significantly higher price range, which effectively places the Xiaomi Watch 5 among the more competitively priced options in its segment in terms of value-to-specification ratio. The device is available in two color options: Black and Juniper Green, both of which are designed to fit either business or casual styling. The review unit received was the green variant.

Technical specifications of the Xiaomi Watch 5

It is worth highlighting a few points for users who may be switching to a smartwatch for the first time. One important aspect is the use of a standard strap mounting system. This is often overlooked during an initial purchase, but it becomes relevant if the watch is intended as a primary device that can be adapted to different styles by changing straps. The use of a standardized attachment mechanism allows for greater flexibility in customization and easier replacement of accessories over time.

Xiaomi Watch 5

I have all four official straps for the AW Ultra 2, and this is an important factor in “refreshing” the look of the device. With smartphones, a similar effect comes from changing the case: when you put on a new one, the device no longer feels like a one- or two-year-old product, but rather something newer. However, moving from subjective impressions to concrete numbers.

Package contents and first impressions

The packaging approach follows the current minimalist trends in consumer electronics, focusing on reduced materials and efficient use of space.

Inside a compact matte cardboard box are the watch with a pre-installed strap, a magnetic charging dock with an integrated cable, and accompanying documentation, including a quick start guide and a warranty card (which is rarely read in practice).

The only significant drawback I noticed with the Xiaomi Watch 5 is the use of a USB-A connector on the charging cable. Since around 2018, I have mostly transitioned to USB-C across my devices, and while I still have a USB-A power adapter, it is essentially reserved for occasional edge cases like this. The charging puck itself is also very lightweight, which gives the impression of a somewhat low-cost component.

Design, case materials, and ergonomics in real-world conditions

The design and structural execution of the Xiaomi Watch 5 suggest a clear focus on build quality and engineering consistency. The case is made of 316L stainless steel, a material commonly used in wearable devices due to its resistance to corrosion, chemical exposure, and mechanical stress. Manufacturing involves a monolithic forming process followed by precision CNC machining, which results in smooth surfaces and consistent geometry, balancing aesthetics with structural durability.

The watch measures 47.0×47.0×12.3 mm and weighs 56 g without the strap. During cycling tests, it feels relatively large and substantial on the wrist. At the same time, the contoured back and balanced weight distribution prevent noticeable discomfort or a pendulum effect, even on uneven surfaces such as cobblestones with frequent vibrations. I wore both devices during testing: my primary watch on the left wrist and the Xiaomi Watch 5 on the right. This is worth noting because, even without prior habit of wearing a watch on that hand, it remained comfortable and did not create a sense of imbalance or obstruction during use.

The display and the heart rate sensor module are protected by dual sapphire glass. On the Mohs hardness scale, this material is rated at 9, making it second only to diamond in terms of natural mineral hardness. In practical terms, this significantly reduces the likelihood of micro-scratches from sand, dust, branches, or incidental contact with bicycle components, which is relevant for maintaining the device’s appearance after extended periods of intensive use.

From my experience with watches in general, I would add that if you are involved in highly active sports, the device should not dictate your behaviour, nor should you be overly concerned about potential cosmetic damage. My unit already has several scratches from mountain trips. When I look at them, I can recall specific situations where they occurred, such as during hikes in the French Alps. The same applies in reverse: I can also see marks on equipment like an ice axe that were caused by contact with the watch.

Xiaomi 17 Ultra

Hygiene is an important consideration for wearable electronics, especially when the device is worn close to continuously. In practice, only one minor aesthetic issue was observed: the chamfered edge around the bezel and the textured surface of the fluororubber strap tend to accumulate fine dust. This requires occasional cleaning of the device, typically using a soft brush.

Xiaomi Watch 5

It is especially important to clean the strap if you are running or engaging in similar sports, as a combination of sweat and dust inevitably leaves traces. This applies to essentially any watch, not just this model. The strap, designed for wrist sizes of 135–205 mm, is described as having hypoallergenic properties and resistance to sweat and prolonged UV exposure. These are generally standard characteristics for this type of material. Overall, these are fairly obvious points, but they are still worth mentioning. The reason is illustrated in the photo below: a watch that was actively used during a run but not wiped down afterward.

Display: Visual experience under direct sunlight

The main interaction interface is a 1.54-inch circular AMOLED display with a resolution of 480×480 pixels. A pixel density of 312 ppi provides clear rendering of small text, navigation maps, and more complex informational watch faces. The use of LIPO (Low Injection Pressure Overmolding) technology enables very thin bezels of 2.6 mm, increasing the usable screen area without enlarging the overall case dimensions. The display has a 60 Hz refresh rate, which ensures smooth scrolling and interface animations when using the HyperOS 3 system.

However, the most important parameter for a device primarily used outdoors remains brightness. The Xiaomi Watch 5 display can reach a peak brightness of up to 1500 nits in HBM (High Brightness Mode). This level is not sustained continuously, but in the context of a smartwatch, the first seconds of viewing are typically sufficient to extract the necessary information. Unlike smartphones, there is rarely a need for prolonged screen interaction in direct sunlight. In practical use under bright sunlight, information remains readable almost instantly, including during running or cycling, without the need to shield the display with a hand. The built-in ambient light sensor responds quickly, adjusting brightness when moving between sunlight, shade, or indoor environments. This contributes not only to usability but also to more efficient overall power consumption.

Hardware platform: dual-chip architecture as a solution to battery life constraints

Historically, one of the main trade-offs of full-featured smartwatches running complex operating systems has been limited battery life. In my earlier Apple Watch usage, I typically needed to charge the device every two days, and during more active periods, even daily. The current Ultra 2 model lasts around two to three days, although it operates on a different OS and within a different ecosystem. Wear OS, in particular, is known to require significant computational resources, which in many cases results in daily charging, at least based on external reviews.

To address this structural limitation, the engineers implemented a dual-chip architecture. The primary processing unit is the Qualcomm Snapdragon W5 Gen 1, manufactured using a 4 nm process. It handles computationally intensive tasks such as third-party applications from Google Play, graphics rendering, navigation, and voice assistant queries via Google Gemini. Alongside it operates an energy-efficient co-processor, the BES2800BP (6 nm process), running a real-time operating system (RTOS).

Xiaomi Watch 5

The key innovation is not merely the presence of two chips, but the intelligent, seamless switching between them depending on the current usage scenario. When the device is in standby mode, displaying the Always-On Display (AOD), counting steps, or performing background heart rate monitoring, only the low-power co-processor is active, keeping energy consumption to a minimum. However, as soon as the user initiates a payment via Google Wallet or opens an application, the system immediately wakes the Snapdragon W5 Gen 1 without noticeable delay.

The hardware configuration also includes 2 GB of RAM and 32 GB of internal storage (UFS standard), which is sufficient for storing offline maps, music libraries, and installing necessary applications. In practice, I noticed only minor, barely perceptible delays when viewing maps during hiking in a live navigation mode. In other scenarios, there were no noticeable signs of reduced responsiveness.

Operating system and software layer: Wear OS meets HyperOS

The Xiaomi Watch 5 runs the global version of Google’s Wear OS, with Xiaomi’s proprietary HyperOS interface layered on top. This combination is intended to merge the broad application ecosystem of Google with Xiaomi’s device integration features. The result is a unified user experience that combines standard Wear OS functionality with additional cross-device interaction tools provided by HyperOS. The steps below do not cover the full pairing process with a smartphone, but they illustrate the main stages of setup and connection.

The presence of Wear OS ensures full support for Google Wallet for contactless payments via the NFC module, the use of Google Maps for pedestrian and transit navigation, and access to the broader Google Play application ecosystem. A notable development is the deep integration of Google Gemini, a generative AI system. Users can interact with it using natural language directly from the wrist, issuing complex queries, receiving detailed responses, or creating contextual reminders (for example, saving the GPS coordinates of a parked car or bicycle via voice input). At present, interaction with Gemini through the watch is text-based on the response side. Voice input is supported, but spoken replies are not yet available. Initial setup was not immediately straightforward. In this case, English-language interfaces were used for testing purposes, as translations vary across languages, and English generally simplifies the configuration process for reviewers.

On the other hand, the Xiaomi HyperOS layer extends the device’s functionality through the Xiaomi HyperConnect architecture and the Smart Hub module. The updated interface features redesigned, smoother animations, improved multitasking logic, and noticeably reduced touch latency. There is also a wide selection of watch faces available. In my case, I preferred a minimalist design. The screenshot below shows only a small portion of them – there are many more available, along with options for customization and even creating your own watch faces.

Xiaomi Watch 5

It should be noted that the device is compatible exclusively with smartphones running Android 8.0 or higher and does not support pairing with iOS devices. Furthermore, access to the most advanced smart features, such as custom gestures for smart home control, requires a connected smartphone running HyperOS 3. In this review, the watch was paired with a Redmi Note 15 Pro, which at the time of writing was still running HyperOS 2, meaning some of these capabilities could not be evaluated in practice.

Interaction revolution: Electromyography (EMG) and gesture control

One of the most discussed and technically significant innovations in the Xiaomi Watch 5 is the integration of a dedicated electromyography (EMG) sensor for contactless gesture recognition. While gesture-based control has appeared in wearable devices before – typically relying on gyroscopes and accelerometers to interpret gross hand movements – the use of EMG sensors represents a substantially higher level of precision, responsiveness, and reliability.

I do not want to overstate this feature, but in my experience with the Apple Watch Ultra 2, gesture control was used only a few times after the initial testing phase following purchase. Because of that, it is understandable that some users may not adopt this interaction model at all, or may not even be aware of its existence, especially since documentation is often not widely read in practice. As mentioned in the previous section, I was unable to properly test this functionality due to the lack of a smartphone running Xiaomi HyperOS 3, which is required to unlock the full set of related features.

Physical principle and recognition mechanism

It is still useful to briefly explain how this technology works. Electromyography (EMG) is a clinical method used to record the bioelectrical activity of muscle tissue and neuromuscular transmission. When the central nervous system sends a signal to the fingers to perform a micro-movement, a weak electrical impulse propagates through the nerves and muscles of the forearm. The EMG sensor integrated into the watch’s rear ceramic panel detects these low-amplitude electrical potentials directly through the skin on the user’s wrist.

By combining raw EMG data with inputs from the optical photoplethysmography (PPG) sensor and the inertial measurement unit (IMU), the device’s proprietary algorithms are able to decode specific finger and wrist movement patterns with high accuracy and minimal perceptible latency.

Practical use in motion

For cyclists, drivers, or users whose hands are occupied or not clean, this type of interaction can be viewed as an alternative input method rather than a core control mechanism.

The operating system supports several basic and user-configurable gestures:

  • Double finger pinch (Pinch twice)
    Default: ending a phone call, stopping a timer, shutter control for the camera.
    Alternatives: answering a call, launching applications.
  • Double finger rub (Rub twice)
    Default: snoozing or dismissing an alarm.
    Alternatives: music playback control, menu navigation.
  • Finger snap (Snap fingers)
    Default: user-configurable action.
    Alternatives: launching Google Gemini, starting a workout.
  • Wrist shake (Shake wrist)
    Default: user-configurable action.
    Alternatives: returning to the home screen, activating the flashlight.

Xiaomi Watch 5

It is worth noting certain ergonomic requirements: for accurate detection of neural impulses, the hand should be in a naturally physiological position (parallel to the chest, with the display facing upward). To conserve battery life, gesture recognition is automatically disabled during sleep detection or when the device switches to Always-On Display (AOD) mode.

Ecosystem synergy: Redmi Note 15 Pro and Mijia Smart Audio Glasses

As an Apple ecosystem user, it was important for me to understand Xiaomi’s ecosystem structure. In practice, the real value of modern flagship devices is typically defined through their interaction within a unified software environment.

However, it became evident that using a Redmi Note 15 Pro running HyperOS 2 does not allow the full feature set of the Xiaomi Watch 5 and the Mijia Smart Audio Glasses to be unlocked within the Xiaomi HyperConnect framework. This framework requires HyperOS 3 along with Xiaomi Home version 10.4 or later. The Mijia brand itself is not new to me – I had previously reviewed several devices from this sub-brand around seven or eight years ago for another publication. However, that is a separate context.

Sports: dual-frequency navigation and health analytics

The sports capabilities of a smartwatch should not be evaluated based on the number of supported workout modes, but rather on the accuracy of health metrics and the stability of navigation systems during real physical activity. It is also important to distinguish between user levels. For professional athletes, devices from ecosystems such as Garmin or Polar are typically more appropriate. The Xiaomi Watch 5 is positioned more clearly for general and amateur fitness use rather than high-performance sports tracking. In this context, the presence of physical buttons on the Xiaomi Watch 5 is a practical advantage during workouts. They provide more reliable control in motion compared to purely touch-based interfaces, especially in situations where precise interaction with the screen is difficult or inconvenient.

For comparison, I decided to take screenshots during a cycling ride using both the Apple Watch Ultra 2 and the Xiaomi Watch 5. Somehow, during the process of taking a screenshot on the Apple Watch, I may have accidentally triggered a touch input or some system action. As a result, I lost a bit more than ten minutes of recorded activity. The watch also did not prompt me to resume the workout from pause, even though I was still riding. Below are screenshots from the Xiaomi Watch 5: before, during, and the final results of that cycling session.

I also came close to losing a segment because the Apple Watch did not automatically resume a paused workout. By default, it is supposed to automatically pause and resume activities, but in this case it did not behave as expected.

What is more inconvenient is that the Apple Watch can occasionally prompt whether to end a workout, offering a “Finish” option. During activities like hiking, this can happen during a normal stop for coffee or a snack. Once triggered, the workout does not automatically continue, and the user has to manually confirm the continuation or restart it. This means you need to closely monitor whether the watch is correctly tracking your activity or whether manual intervention is required to avoid missing segments. With the Xiaomi Watch 5, this kind of behavior is less likely, as activity tracking appears to rely more on explicit, user-driven control rather than automatic state changes.

Xiaomi Watch 5

The reason I mention this is that, with the Xiaomi Watch 5, most of these actions are under manual user control. In some scenarios, this can be seen as a drawback, but my experience suggests that overly automated systems are more likely to lead to data loss or incorrect triggers. When you have direct control over actions – especially with the help of physical buttons – the likelihood of such errors is reduced. Below is what the analysis of that same running session looks like. I should also note that I am an amateur rather than a professional runner (and, frankly, I dislike running).

For reference, I am also attaching data from the Wahoo ELEMNT Roam cycling computer and the Xiaomi Watch 5 from the same ride. The moment of the Apple Watch issue can also be seen in the training duration display. At that point, the rest of the recorded data for that segment was effectively lost.

Sensors and comprehensive health analytics

The Xiaomi Watch 5 is equipped with an advanced biometric module that includes 4 LEDs and 4 photodiodes. This extended optical configuration is designed to enable continuous background monitoring of key physiological parameters.

Heart rate and oxygen saturation monitoring: The device tracks heart rate (HR) 24/7, generating detailed graphs and providing vibration alerts when unusually high or low resting heart rate values are detected. Blood oxygen saturation (SpO₂) is measured automatically every 10 minutes, which can help indicate potential signs of hypoxia. Of course, these metrics should not be treated as medical-grade diagnostics. Any important health-related decisions should always be made in consultation with a qualified healthcare professional. At the same time, such devices can serve as a useful early reference point that may prompt further attention or medical evaluation when needed.

Xiaomi Watch 5

Stress management and recovery: Stress management is a particularly relevant feature in this context, although it is understandable that some users may choose to ignore it, as I did in practice. By analysing heart rate variability (HRV), the system continuously estimates the user’s physiological stress level using onboard algorithms. During periods of elevated stress, the device can proactively suggest breathing exercises via a dedicated app, guiding the user through the process with visual cues and haptic feedback.

Sleep analysis (somnology): In close integration with the Mi Fitness application, the watch performs a detailed analysis of sleep quality. The system identifies REM (rapid eye movement) phases, records breathing rate, and measures blood oxygen saturation throughout the night. The collected data is supplemented with personalized recommendations aimed at improving sleep hygiene.

Compared to some other ecosystems that primarily present raw metrics, these recommendations are more action-oriented, offering clearer guidance on what adjustments might be useful.

One-tap health assessment: The “One-tap health assessment” feature allows the device to collect key biometric data in approximately 60 seconds and compile it into a consolidated report. The result is a quick overview of the current physiological state displayed directly on the watch screen.

Navigation and mapping

For users with an active lifestyle, the system offers support for over 150 sports modes, including dedicated profiles for running, cycling, swimming, and high-altitude hiking. The device is rated at 5 ATM water resistance (up to 50 meters), making it suitable for structured swimming training in pools or open water. At the same time, the manufacturer typically advises against using the device in hot showers, saunas, or high-pressure water sports.

A key highlight is the integrated navigation module. The Xiaomi Watch 5 is equipped with a dual-frequency GNSS system supporting simultaneous L1 and L5 bands and compatibility with five major satellite constellations: GPS, Galileo, GLONASS, BeiDou, and QZSS. The use of the L5 frequency is particularly important for reducing multipath signal errors, where radio waves are reflected from dense urban infrastructure or tree cover, leading to inaccuracies in positioning. In testing, GPS tracking proved to be consistently accurate, avoiding the typical “jumping” of routes onto adjacent streets or nearby objects that is often seen in lower-cost single-frequency systems.

An additional advantage for hikers and travelers is support for full-color vector offline maps. Map packages can be quickly downloaded to the watch’s internal storage via the Mi Fitness interface. During standalone navigation, the device displays the route in detail on the screen and provides timely haptic feedback when turning instructions are needed or when the user deviates from the planned path. The back-to-start navigation function is designed to help users return to the starting point even in areas without any cellular network coverage.

Xiaomi Watch 5

In addition to the intrinsic satisfaction from physical activity and reviewing performance analytics, it is often also useful to share results through platforms such as Strava or similar services. This functionality is supported here as well. A screenshot illustrating the workflow is included below on the portal. If you would like to follow my activity on Strava, feel free to leave a comment, and I will share the link.

Battery life: silicon-carbon breakthrough

This is one of the key strengths of the Xiaomi Watch 5. Historically, one of the main limitations of Wear OS-based smartwatches has been the need for daily charging, and in some cases even more frequent recharging. The Xiaomi Watch 5 significantly challenges this expectation by combining advanced battery chemistry with an optimized dual-chip architecture.

The battery capacity, developed under Xiaomi Surge technology, is an unusually high 930 mAh for this form factor. Achieving this energy density without a proportional increase in size or weight is made possible through the use of silicon-carbon materials, which account for approximately 10% of the anode composition.

  • Power-saving mode
    Claimed duration: up to 18 days.
    Practical experience: not tested extensively, as the device was used continuously rather than left in a low-power state.
  • Smart mode
    Claimed duration: up to 6 days.
    Practical experience: around 4.5–5 days under intensive usage, which is a strong result for this class of device.
  • Smart mode + AOD (Always-On Display)
    Claimed duration: up to 4 days.
    Practical experience: approximately 3–3.5 days with active GPS and audio usage, which remains a solid outcome in real-world conditions.

Xiaomi Watch 5

Observations under real, intensive usage conditions confirm the effectiveness of these engineering decisions. Active use of the device – including cycling workouts with dual-frequency GPS enabled, hiking, handling notifications and messages from a Redmi Note 15 Pro smartphone, controlling audio playback on Mijia Smart Audio Glasses, and continuous blood oxygen monitoring – results in a battery drain of approximately 15–25% per day. Even under the most demanding usage scenarios, the device consistently delivers between 3 and 5 full days of operation without recharging. This is a strong result for a full Wear OS implementation and places it ahead of most competing devices in the global market in terms of endurance. The screenshot below illustrates a case where all background features were enabled simultaneously, including continuous SpO₂ monitoring and Always-On Display (AOD).

Conclusions

As an engineering analyst by education, I primarily focus on data. An analysis of the technical specifications, hardware components, and software algorithms of the Xiaomi Watch 5 – supported by real-world testing within a connected ecosystem including the Redmi Note 15 Pro and Mijia Smart Audio Glasses – leads to a clear conclusion. The company has successfully transitioned from producing mid-range wearable devices to developing mature, fully-fledged premium products capable of setting new quality benchmarks in the market. This is also reinforced by a subjective, but still relevant, aspect: the perception of the device’s premium character is not only noticeable to the user but is also often recognized by others.

Key strengths of the device: First, the use of 316L stainless steel and sapphire glass provides strong durability and a more traditional, refined aesthetic, allowing the device to withstand demanding real-world conditions. Second, the architectural combination of the Snapdragon W5 Gen 1 and BES2800BP processors delivers solid Wear OS performance without significantly compromising battery life. Third, the 930 mAh battery, based on silicon-carbon technology, enables roughly 3 to 6 days of typical smartwatch usage, addressing one of the main limitations commonly associated with Google’s wearable platform. Fourth, EMG-based gesture controls function reliably and offer a genuinely practical contactless interaction method, particularly useful during physical activity. Finally, the deep integration of HyperOS 3.0 and the Smart Hub module allows the device to operate more cohesively within a broader ecosystem of smartphones and audio devices, reducing friction in everyday digital workflows. This ecosystem aspect is something I would like to explore further, as it becomes increasingly clear that full understanding of such systems often requires extended, long-term usage rather than short testing cycles.

Objective limitations: Despite its technological maturity, the device has several clear constraints. The watch is compatible exclusively with Android smartphones, leaving iOS users outside of this ecosystem. That said, this is consistent with the broader industry approach, as Apple similarly restricts full smartwatch functionality to its own platform. In addition, some advanced ecosystem features – such as custom EMG gestures for smart home control – are only fully available when paired with smartphones running the latest version of HyperOS 3.

Overall, the Xiaomi Watch 5 goes beyond being just another smartwatch with extended heart rate and sleep tracking. With access to Google services, integration of the Gemini generative AI assistant, reliable dual-frequency navigation, and strong battery endurance, the device functions more like a compact digital hub on the wrist. It handles both demanding urban environments and longer cycling or hiking activities well, demonstrating that advanced technology can be integrated into a practical lifestyle without constant concern about battery life or charging routines. Given its pricing strategy at around €300, the model has the key characteristics needed to position itself as a competitive flagship option in the European market within the current product cycle.

P.S. I’m already looking forward to the next Xiaomi gadget to review – and it’s going to be absolutely brilliant! Those in the know will know.
