Introduction to the Mi Band 10
Overview of the Mi Band Series
The Mi Band series by Xiaomi has become synonymous with affordability, functionality, and sleek minimalist design in the world of fitness trackers. Since its inception, the Mi Band lineup has steadily evolved, bringing in new sensors, better displays, and more refined software integrations with each release. From the basic step and sleep trackers of the Mi Band 1 to the full-color AMOLED-equipped Mi Band 9 Pro, Xiaomi has pushed its wearables toward increasingly sophisticated health tracking.
The Mi Band 10 marks yet another leap. Touted as a budget-friendly device with professional-grade sensors, it claims to offer heart rate monitoring, sleep stage tracking, exercise detection, and even SpO2 measurement, all at a fraction of the cost of high-end competitors. But how much of that is marketing, and how much is science-backed reality? That’s what this review sets out to explore.
What Makes the Mi Band 10 Unique?
The Mi Band 10 retains many of the physical and software characteristics of its predecessors, but there are some noticeable upgrades:
- A more refined heart rate sensor for better real-time monitoring.
- Allegedly improved sleep tracking algorithms.
- Extended battery life, even with continuous tracking features turned on.
- Integration with Apple Health, Strava, and other fitness ecosystems.
What truly sets this device apart is its price-to-performance ratio. For under $50, you get a device that, on paper, rivals wearables costing five times more. But as with any scientific claim, these must be tested under controlled conditions to validate performance.
Purpose of This Scientific Review
Rather than relying on user impressions or general reviews, this article takes a scientific approach to validate the accuracy, reliability, and practical usability of the Mi Band 10. The aim is to:
- Evaluate heart rate accuracy against gold-standard devices like the Polar H10 chest strap.
- Compare sleep tracking performance against an EEG-based headband.
- Test the device across multiple exercises: indoor cycling, outdoor cycling, weightlifting, and running.
- Identify any syncing issues, device inconsistencies, and real-world usability challenges.
The final goal? To help fitness enthusiasts, athletes, and everyday users decide if the Mi Band 10 is worth the money—or just another cheap tracker with inflated claims.
First Impressions and Unboxing Experience
Packaging and Design Highlights
The Mi Band 10 arrives in typical Xiaomi fashion: simple, minimal, and straight to the point. The packaging doesn’t scream “premium,” but it’s functional and protective. Inside, you’ll find:
- The Mi Band 10 itself (available in black, white, and other subtle tones)
- A USB-A charging cable (still no USB-C, unfortunately)
- A quick start guide and warranty slip
The tracker boasts a sleek rectangular body, equipped with an AMOLED screen that’s bright enough for outdoor visibility. The silicone strap is comfortable but may need upgrading for those with sensitive skin or larger wrists.
Design-wise, the Mi Band 10 feels familiar, but slightly more refined. The touchscreen is responsive, the build quality is surprisingly solid, and the device is incredibly lightweight—making it suitable for 24/7 wear.
What’s Inside the Box?
Here’s a quick breakdown of what you’re getting:
| Item | Details |
|---|---|
| Fitness Tracker | Xiaomi Mi Band 10 (AMOLED, waterproof) |
| Charging Cable | Magnetic USB-A proprietary charger |
| Manual | Quick start guide in multiple languages |
| Strap | Pre-installed silicone strap |
Setup requires downloading the Mi Fitness app, creating a Mi account, and connecting the tracker via Bluetooth. The process is relatively quick, though some users report needing to retry the pairing a couple of times—especially when syncing with Strava or Apple Health.
Initial Setup and Connectivity
One of the first hurdles with Xiaomi wearables is account synchronization. For this review, two Mi Band 10s were tested—each paired with a separate iPhone and a separate Mi account. The aim was to observe any variability or software-related issues.
Here are the key findings during setup:
- The Mi Fitness app is intuitive but still lacks some polish.
- Syncing to Apple Health and Strava can be inconsistent; one device initially failed to push workout data to Strava.
- Once configured properly, both devices updated firmware quickly and were ready for use in under 10 minutes.
Though initial setup was straightforward, getting consistent access to raw data proved difficult—a recurring issue with Xiaomi’s closed ecosystem.
Testing Methodology Explained
Devices and Tools Used for Accuracy Checks
To conduct a scientific review, reliable reference devices were used. These included:
- Polar H10 Chest Strap: A gold standard for heart rate monitoring
- Zmax EEG Headband: For accurate sleep stage measurement
- Garmin Watch: As an additional heart rate and activity comparator
- Whoop Strap 4.0: Known for real-time recovery insights
Each Mi Band 10 was worn on either wrist during workouts and sleep, while reference devices captured parallel data for later comparison.
Scientific Approach to Fitness Tracking Tests
Every test scenario was designed with controlled variables:
- Devices were worn simultaneously for cross-validation
- Environmental factors like room temperature, exercise duration, and motion intensity were recorded
- Sleep studies included manual time-logging, motion detection, and EEG wave pattern comparison
Heart rate data was analyzed using scatter plots and correlation graphs, where the closer the data points hugged the diagonal blue line, the more accurate the Mi Band 10 was.
Sleep data was broken into stages:
- Light Sleep
- Deep Sleep
- REM Sleep
- Awake Periods
The sleep stage detection rates were then mapped against the EEG-based headband to determine pattern consistency and prediction accuracy.
Experiment Design and Conditions
The Mi Band 10 was tested over the course of a full week with the following exercises:
- Indoor Cycling (30 mins) – Constant cardio with minimal motion disruption
- Outdoor Cycling (35 mins) – Varying heart rate and environmental conditions
- Weightlifting (45 mins) – Focus on short bursts, heavy arm strain
- Running (30 mins) – Steady pace on mixed terrain
- One Full Night of Sleep – Simultaneous wearing of both bands plus EEG headband
Special attention was given to syncing intervals, sensor response times, and battery performance during all activities.
Heart Rate Monitoring Performance
Indoor Cycling: Accuracy and Real-Time Data
The Mi Band 10 was first put to the test in a stationary indoor cycling session, where both bands were worn simultaneously with the Polar H10 chest strap serving as the benchmark.
The results were astonishing.
- Both Mi Band 10s maintained an average correlation of 0.99 with the Polar H10.
- Graphs showed that the heart rate values almost perfectly overlapped with the chest strap readings.
- The device responded rapidly to intensity changes, displaying values in near real-time with minimal delay.
This level of performance from a sub-$50 wearable was unexpected and rivals premium trackers in this category. It suggests that Xiaomi has significantly upgraded their PPG (Photoplethysmography) sensor and possibly optimized the sampling frequency.
Outdoor Cycling: Variability and Tracking During Motion
Outdoor cycling introduced more variables—terrain shifts, arm vibrations, and weather. Here’s what happened:
- One Mi Band (right wrist) scored a correlation of 0.91, showing some deviation in the second half of the ride.
- The other (left wrist) performed better with a correlation of 0.96, closely matching the reference.
- Temperature seemed to play a role—higher temps improved sensor signal stability.
Even with minor inconsistencies, the heart rate data was within an acceptable accuracy range for casual and even some professional training scenarios.
Weightlifting: Arm Tension and Data Challenges
When it comes to weightlifting, most wrist-worn fitness trackers face a common challenge: the tension and compression of the wrist muscles during lifts tend to distort optical heart rate readings. The Mi Band 10 is no exception, but it still managed to put up a surprisingly decent fight.
Two sessions were tested—one focused on chest and triceps, and another on back and biceps, with both Mi Band 10 devices worn throughout. The Polar H10 served as the reference heart rate source.
Here’s what the analysis revealed:
- The correlation for the left wrist was 0.89, while the right wrist device performed slightly better at 0.92.
- Most of the low-intensity moments, such as rest between sets, were measured accurately.
- During high strain lifts, the Mi Band 10 had a tendency to underreport heart rate spikes, particularly when muscles were contracted tightly near the device.
Graph analysis showed that the red line (Mi Band 10) often lagged behind the blue reference line during peak exertion. This suggests that while the tracker can follow general trends, it lacks the sensitivity for rapid cardiac fluctuations under strain.
This is not a unique failure—Apple Watch and Garmin devices also show inaccuracies during static strength training. It’s why fitness enthusiasts are often encouraged to pair a chest strap monitor for strength workouts, especially when heart rate is a critical training metric.
Still, a 0.92 correlation during weightlifting is impressive for this price range. It surpasses earlier Mi Bands and is on par with Huawei Watchfit and Fitbit Charge models tested under similar conditions.
Running: Real-World Testing on Different Terrains
Running is often considered a litmus test for wearable heart rate trackers. It requires the device to keep up with continuous motion, variable pace, and arm swing, all while maintaining signal stability.
During the test, both Mi Band 10s were used during a 30-minute steady-state outdoor run. The reference device was, once again, the Polar H10.
Results were, in a word, outstanding:
- The Mi Band 10 on the left wrist showed a perfect correlation of 1.00.
- The one on the right wrist followed closely with a 0.99 correlation.
- The heart rate graph showed an almost identical curve to the chest strap, with only a minor delay during the first 10–15 seconds.
From warm-up to cool-down, the Mi Band 10 tracked heart rate with unprecedented accuracy for a device in this price class. The only notable issue? A 2–3 second latency in detecting sudden pace increases. However, that’s hardly a deal-breaker for most users unless they’re interval training professionals.
This performance places the Mi Band 10 shoulder-to-shoulder with some of the best running wearables, including the Fitbit Charge 6, Garmin Forerunner 55, and Whoop Strap 4.0.
Mi Band 10 vs Other Fitness Trackers
Mi Band 10 vs Polar H10 Chest Strap
Throughout the tests, the Polar H10 was the gold standard. It’s a chest strap that uses electrocardiogram (ECG) technology, meaning it captures electrical signals directly from the heart—making it far more accurate than optical sensors.
Against this high benchmark, the Mi Band 10 held up impressively:
- Indoor cycling: Correlation 0.99
- Outdoor cycling: Correlation 0.91–0.96
- Weightlifting: Correlation 0.89–0.92
- Running: Correlation 0.99–1.00
While not flawless, these numbers make it one of the most accurate wrist-based trackers under $100 and possibly even under $200.
Comparison With Apple Watch and Fitbit
Now let’s stack it up against some more expensive competition:
| Device | Avg. HR Correlation | Price | Strengths |
|---|---|---|---|
| Mi Band 10 | 0.94–0.99 | ~$40–$50 | Heart rate accuracy, affordability |
| Apple Watch Series 8 | 0.98–1.00 | ~$399 | App ecosystem, recovery metrics |
| Fitbit Charge 6 | 0.94–0.98 | ~$129 | Google Fit integration |
| Huawei Band 9 | 0.92–0.96 | ~$59 | Screen size, similar HR tracking |
In terms of heart rate tracking, the Mi Band 10 actually holds its own and even outperforms some Fitbits and older Garmin models. However, it falls short in areas like:
- Sleep tracking accuracy
- App functionality
- Smart notifications and ecosystem integration
Price-to-Performance Analysis
Perhaps the most compelling argument for the Mi Band 10 is its price-to-performance ratio. For roughly the cost of a family dinner, you’re getting:
- Accurate cardio heart rate monitoring
- Simple UI and good battery life
- Compatibility with Apple Health and Strava
It may lack the polish and data granularity of premium brands, but for everyday athletes, casual runners, and gym-goers, it delivers way more than expected.
If you need precise training feedback, workout zones, and long-term recovery trends, you’re better off with a Whoop, Apple Watch, or Garmin. But if your goal is budget fitness tracking with surprisingly reliable heart rate accuracy, the Mi Band 10 is hard to beat.
Sleep Tracking Capabilities
Setup for Sleep Monitoring
When it comes to sleep tracking, the Mi Band 10 promises to provide insights into your sleep stages, including light sleep, deep sleep, REM, and awake periods. Setting up the device for sleep monitoring is as easy as wearing it overnight and syncing it with the Mi Fitness app the following morning.
To test its accuracy, two Mi Band 10 devices were worn simultaneously on each wrist during the same night. Additionally, the Zmax EEG headband—a device capable of detecting brain waves and sleep stages with high precision—was used as the reference standard. The experiment aimed to assess how closely the Mi Band 10 could match the EEG-based readings.
Initial results showed that both bands collected data without issue. However, analyzing the actual sleep stages uncovered some surprising discrepancies that challenge the Mi Band 10’s reliability in this domain.
Nightly Performance and Consistency Between Bands
For any fitness tracker to be reliable in sleep tracking, it should at the very least provide consistent results when worn under the same conditions. Unfortunately, the Mi Band 10 failed to meet this basic criterion.
Here’s what was discovered:
- The two devices produced significantly different sleep stage breakdowns from the same night.
- While sleep start and end times were fairly aligned, the classification of sleep phases (especially REM and deep sleep) differed greatly between the two bands.
- One band recorded large amounts of deep sleep in the latter half of the night, while the other barely registered any during the same period.
This inconsistency raises questions about the algorithmic accuracy of the Mi Band 10. If two devices worn on the same body produce different interpretations of the same sleep, it implies that sleep tracking is not yet mature in Xiaomi’s ecosystem.
In contrast, reference devices like the Zmax EEG headband consistently captured well-structured sleep cycles, including the typical pattern of light to deep to REM sequences that align with human circadian rhythms. These cycles were largely absent or distorted in the Mi Band’s output.
Comparison With EEG-Based Reference Devices
The Zmax EEG headband allowed a direct, scientific comparison between true brain activity and Mi Band 10’s interpretations. The result? A mismatch in both accuracy and consistency.
Let’s break it down numerically:
| Sleep Stage | EEG Accuracy (Reference) | Mi Band 10 Accuracy (Best Band) |
|---|---|---|
| Deep Sleep | 100% | ~90% |
| Light Sleep | 100% | ~52% |
| REM Sleep | 100% | ~48% |
These numbers were derived by matching the predicted stages from the Mi Band with the actual stages from the EEG data. Ideally, all predictions should align with the EEG. Unfortunately, only deep sleep showed high agreement, while light and REM stages were significantly misclassified or misplaced.
Even more concerning was the fact that one Mi Band 10 performed much worse than the other, showing an average accuracy of just 41% across sleep stages, with REM sleep accuracy dipping below 40%.
These inconsistencies suggest that the Mi Band 10’s sleep stage tracking algorithm is either under-trained or lacks the precision to accurately interpret biometric data under varied sleep conditions.
Sleep Stage Breakdown Analysis
The final piece of the sleep puzzle lies in how well the Mi Band 10 can represent realistic sleep architecture. This means following predictable patterns like:
- Initial deep sleep dominance
- Gradual increase in REM stages
- Regular transitions every 90 minutes (a full sleep cycle)
While the EEG device clearly displayed these cycles, the Mi Band 10 showed randomly distributed sleep stages, especially for REM periods, which should ideally occur towards the latter half of the night. This undermines the clinical usability of the device for sleep tracking purposes.
Here’s a visual breakdown from the experiment:
- The reference device showed 5 complete sleep cycles, each ending in REM.
- The Mi Band 10, in contrast, recorded REM scattered throughout the night with no visible cycle structure.
As a result, anyone relying on the Mi Band 10 for deep insights into sleep health—such as tracking recovery, memory consolidation, or REM-related mood changes—may find the data misleading or inaccurate.
Data Visualization and Analysis
Understanding Heart Rate Graphs
Visual data representation plays a huge role in fitness tracking—after all, what good is accurate data if you can’t interpret it? Fortunately, the Mi Fitness app does offer basic line graphs showing heart rate over time, but it lacks deeper features found in apps like Garmin Connect or Whoop.
To perform a proper analysis, raw data was exported (with some effort) and graphed using external software.
Each graph contained:
- A blue line for the reference device (Polar H10)
- A red line for the Mi Band 10
- A time-based horizontal axis (x-axis)
- A heart rate-based vertical axis (y-axis)
In most workouts (especially running and indoor cycling), the red and blue lines tracked nearly identically, confirming that the Mi Band 10 was capturing changes in heart rate in real time with minimal delay.
During high-motion or high-tension activities like weightlifting, however, the red line occasionally lagged, particularly around heart rate peaks, illustrating the limitations of wrist-based optical sensors.
Interpreting Sleep Stage Plots
The sleep graphs were much more problematic. Although the Mi Band 10 does offer a color-coded sleep timeline, it’s relatively superficial and lacks scientific rigor.
To truly evaluate its accuracy, custom plots were made to compare:
- Actual EEG-determined sleep stages
- Mi Band 10-predicted stages from both wrists
This side-by-side comparison clearly showed that:
- Sleep stage detection was inconsistent
- There were false positives for deep sleep
- REM stages were misclassified or misplaced
This poor alignment emphasizes that while the Mi Band 10 excels in cardiovascular monitoring, it falls flat on neurological sleep interpretation.
Correlation Metrics and What They Mean
The true power of this review lies in its use of correlation analysis—a statistical method used to determine how well two data sets align. In this case, it measured how closely the Mi Band 10’s readings matched reference standards.
- A correlation of 1.00 = perfect agreement
- A correlation of 0.90+ = very good agreement
- A correlation of 0.80–0.89 = acceptable
- Below 0.80 = not reliable
Here’s a quick look at how the Mi Band 10 scored:
| Activity | Correlation Score (Left Wrist) | Right Wrist |
|---|---|---|
| Indoor Cycling | 0.99 | 0.99 |
| Outdoor Cycling | 0.96 | 0.91 |
| Weightlifting | 0.89 | 0.92 |
| Running | 1.00 | 0.99 |
| Sleep Tracking | 0.54 (avg.) | 0.41 (avg.) |
These numbers tell a compelling story: the Mi Band 10 is a top-tier heart rate tracker for the price, but its sleep tracking algorithm needs major refinement.
Strengths of the Mi Band 10
Accuracy in Standard Cardio Workouts
Perhaps the biggest surprise during testing was how consistently accurate the Mi Band 10 proved to be in standard cardio sessions. Whether it was indoor cycling, outdoor biking, or steady-state running, the device maintained a high correlation (0.96 to 1.00) with professional-grade heart rate monitors like the Polar H10 chest strap.
Key takeaways from cardio testing:
- Rapid response to changing heart rates, especially in running.
- Minimal latency in reading spikes and drops.
- Surprisingly close overlap in data plots with the reference devices.
This kind of performance from a budget tracker is rare. Devices from more recognized fitness brands like Fitbit and Garmin tend to perform similarly but at 2x to 6x the price. For someone who focuses primarily on endurance workouts, HIIT sessions, or even commuter cycling, the Mi Band 10 stands out as an accurate and affordable heart rate solution.
Performance in Warm Weather
A fascinating but somewhat underexplored advantage of the Mi Band 10 was its strong performance in warm conditions. The testing took place in a setting where the ambient temperature was consistently above 27°C (80°F), which likely contributed to:
- Improved peripheral blood flow, especially in the arms and wrists.
- Stronger optical signal pickup by the photoplethysmographic (PPG) sensor.
It’s speculated that warmer weather conditions improve the blood perfusion, thereby enhancing the light-based measurement capabilities of wrist-worn sensors. While this hypothesis needs more empirical validation, it’s worth noting that the Mi Band 10’s best performances were recorded during hot weather.
This suggests that those living in tropical or warmer climates might experience even better tracking accuracy than users in colder regions.
Affordability and Value for Budget Users
Let’s talk price. The Mi Band 10 retails for under $50, and you can sometimes find it for as low as $35 during sales. For that price, here’s what you get:
- AMOLED display that’s readable in daylight.
- Accurate heart rate tracking across most exercise types.
- Basic sleep insights (albeit less reliable).
- Integration with platforms like Apple Health and Strava.
- Long battery life – typically 10–14 days with normal usage.
That’s a staggering value proposition. In comparison:
- Fitbit Charge 6 starts at $129
- Garmin Vivosmart 5 starts at $149
- Apple Watch SE starts at $249
While these alternatives offer more comprehensive features, the Mi Band 10 delivers a solid 80–90% of their core fitness tracking ability at a fraction of the price. If your main goal is to monitor heart rate, steps, and calories burned, it gets the job done with flying colors.
Weaknesses and Limitations
Inconsistent Sleep Tracking
This is the Achilles’ heel of the Mi Band 10. Despite marketing claims of improved algorithms, the device failed to provide consistent or reliable sleep stage data. Here are the core issues:
- Mismatch between devices worn on the same person during the same night.
- Random distribution of REM sleep, which doesn’t align with known sleep architecture.
- Poor agreement with EEG reference devices, especially in REM and light sleep detection.
Even casual users may find the sleep insights unreliable or confusing. If accurate sleep analysis is important to you—whether for recovery, mental health, or productivity—the Mi Band 10 falls short.
In contrast, even older devices like the Fitbit Charge 4 or Apple Watch SE offer much more accurate and structured sleep reports.
Software Sync Issues
While hardware performance exceeded expectations, the Mi Fitness app experience left a lot to be desired. Here’s what testers encountered:
- Initial sync failures with platforms like Strava and Apple Health.
- Inconsistent data retrieval, especially with sleep records.
- Limited export options for raw data.
The UI is clean but lacks the depth and polish of apps like Garmin Connect, Whoop, or Oura. Xiaomi has made progress in improving usability, but the app still feels clunky and underdeveloped, especially for data-centric users who want more insights and control.
Limitations in High-Intensity or Static Movements
Although the Mi Band 10 shines during cardio, its performance drops significantly during static strength-based workouts. Examples include:
- Weightlifting
- Yoga or Pilates
- Isometric exercises
During these sessions:
- Muscle contractions distort the PPG signal
- Heart rate spikes are missed or delayed
- Accuracy drops to 0.89 or lower
These issues are common among all wrist-based trackers, not just the Mi Band. However, they highlight the importance of using chest straps or arm-based sensors if you’re serious about tracking your workouts with precision.
Real-World Usability and Comfort
Wearing the Mi Band 10 Daily
If you’re planning to wear the Mi Band 10 around the clock, good news: it’s built for comfort. The lightweight body and soft silicone strap make it barely noticeable on your wrist. Even during sleep, it’s non-intrusive—which is essential for any 24/7 wearable.
Some small notes:
- The strap may feel snug during exercise if you sweat a lot.
- There’s a tendency for moisture buildup, so regular cleaning is recommended.
- Users with larger wrists may need to upgrade to a third-party strap for better fit and comfort.
Despite those minor issues, the Mi Band 10 scores high for long-term comfort and wearability.
Battery Life and Charging Speed
Battery life has always been a highlight in the Mi Band series, and version 10 continues that tradition. Here’s what you can expect:
- Up to 14 days of battery with light usage
- 8–10 days with heart rate and sleep tracking enabled
- Full recharge in under 90 minutes using the included magnetic USB charger
The charger, unfortunately, still uses USB-A, which feels a bit dated in 2025. A move to USB-C would’ve been welcomed. Nonetheless, the battery performance is excellent, especially compared to smartwatches that need to be charged daily.
App Interface and Sync Capabilities
The Mi Fitness app is functional but not feature-rich. Here’s a breakdown:
| Feature | Performance |
|---|---|
| UI Design | Clean, simple, beginner-friendly |
| Data Sync | Inconsistent; may require re-pairing |
| Data Export | Very limited |
| Third-Party Integration | Partial (Strava, Apple Health, Google Fit) |
| Notifications | Basic and sometimes delayed |
Advanced users who expect deep trend analysis, customizable dashboards, or training suggestions will likely be disappointed. For casual tracking, it works—but it leaves room for growth.
Ideal User Profile
Who Should Consider the Mi Band 10?
The Mi Band 10 isn’t trying to be everything for everyone—but for the right user, it hits a sweet spot of functionality and affordability. So who is that ideal user?
Here’s who will benefit the most:
- Casual fitness enthusiasts who want to track heart rate, steps, and workouts without breaking the bank.
- Students, beginners, or budget-conscious users looking for a reliable device for everyday use.
- Cyclists, runners, and cardio-focused athletes who prioritize heart rate tracking over other advanced metrics.
- Users who want a lightweight, comfortable, and discreet tracker to wear 24/7.
- People who exercise primarily in warmer climates, where sensor accuracy is enhanced.
It’s perfect for those who want actionable fitness data without the complexities or costs of high-end wearables. If you’re not overly focused on sleep tracking or advanced smartwatch features, the Mi Band 10 delivers exceptional value.
When It’s Better to Invest in Premium Alternatives
That said, the Mi Band 10 isn’t for everyone. Here are the cases where a more premium device may be a better fit:
- If you’re focused on accurate sleep stage tracking (especially REM and deep sleep), consider the Apple Watch, Oura Ring, or Whoop Strap.
- If you’re an athlete who relies on interval heart rate zones, VO2 max estimates, or training readiness, a Garmin Forerunner or Polar Vantage may serve you better.
- If you want rich app insights, goal tracking, and adaptive coaching, platforms like Fitbit Premium or Whoop’s Health Monitor offer a better UX.
- For those needing ECG, skin temperature, HRV, and SpO2 data accuracy, the Mi Band 10 will feel too basic.
So, while the Mi Band 10 impresses in specific use cases, it’s not a replacement for comprehensive health ecosystems or athlete-grade wearables.
Final Verdict – Is Xiaomi Mi Band 10 Worth It?
