Compare Xiaomi Smart Band 9 Active vs Samsung Galaxy Fit3

Heart rate accuracy was mixed to poor: easy workouts could be close, but several reviewers found unstable, high, or plainly inaccurate readings.

Heart-rate accuracy was one of the better-tracked areas, often close to reference devices, though intense intervals could expose lag or variance.

GPS-related accuracy was a common limitation, with no built-in GNSS and poor GPS readings compared with phone data.

GPS accuracy was a major limitation because the Fit3 lacks built-in GPS and depends on a phone for better outdoor tracking.

Sleep tracking split reviewers: several found it solid or accurate for timing, while GSMArena found sleep and wake times inaccurate.

Sleep tracking drew the most mixed evidence: several reviewers found it good or accurate, while others reported gaps, overestimates, missed wake periods, or low confidence.

Guided workout support was limited in comparative testing, with one reviewer saying the missing training functions were useful and missed.

Guided workouts were valued because Samsung Health training programs were free.

Swimming tracking was a weak point because reviewers repeatedly noted the lack of a swim mode despite the water-resistance rating.

Swimming tracking received positive feedback for lap and swim-type tracking, though one review lost swim data after a sync issue.

Fitness coaching was limited; one reviewer missed training-style functions such as Running Courses, Training State, and Vitality Score.

Fitness coaching evidence was positive where sleep coaching and Samsung Health guidance were described as genuinely useful.

Stress tracking was considered welcome, clear, or handy, but reviewers also cautioned that it should not be treated as perfectly accurate.

Stress tracking was one of the weaker health metrics, with reviewers saying it misread calm or stressful moments.

Workout tracking accuracy leaned negative: indoor rowing looked acceptable, but outdoor and general workout metrics were repeatedly off.

Workout tracking was broadly praised for casual fitness, though detailed training accuracy was not strong enough for serious athletes.

Activity accuracy was inconsistent: three reviewers reported underreported or inaccurate activity metrics, while one found step count and activity detection accurate for basic use.

Reviewers generally found basic activity readings useful and often accurate enough, though the evidence is about broad tracking rather than athlete-grade precision.

Workout variety was acceptable for basics and entry-level use, but reviewers also noted the mode count is reduced versus other Xiaomi bands.

Workout mode variety was a clear strength, with reviewers repeatedly noting more than 100 activities and broad coverage.

Step counting drew mixed evidence, with two reviewers reporting undercounts or large gaps versus other trackers and one saying step and activity detection were accurate.

Step counts were usually close or good in simple tests, but a few reviewers saw ghost or fake steps, making this mostly positive with caveats.

Cadence-style rowing data was a bright spot in Wareable testing, where strokes per minute matched the rower closely.

Cadence tracking scored strongly in one controlled comparison where cadence matched the Apple Watch Ultra 2 exactly.

Connected GPS reliability was criticized by TechRadar, which linked distance loss to how the band connects to the phone.

Connected GPS was specifically described as affecting tracking accuracy and proving fiddly in at least one review.

Blood oxygen tracking was treated as useful guidance rather than clinical data, with one reviewer praising all-day SpO2 as rare at the price.

Blood oxygen tracking was viewed positively, including on-demand readings and close readings against a pulse oximeter in some testing.

Sleep stage tracking was received well in the reviews that tested it, with useful REM, light, and deep-sleep breakdowns.

Sleep-stage tracking was useful in presentation but inconsistent in accuracy, with gaps or questionable awake-time estimates in some reviews.

Calorie tracking was not trusted by two reviewers, who called the estimates surprisingly low or dubious.

Calorie tracking was criticized as too generic for some workout modes rather than deeply useful.

Resting heart rate tracking had one positive review, with Wareable finding the resting heart rate trends pretty in tune with rival devices.

Resting heart-rate tracking was described as accurate for basic steady-state monitoring.

Distance tracking was a repeated weakness, with reviewers describing discrepancies, short run distances, underreported totals, and about 20% distance loss.

Distance estimates suffered when the tracker lacked reliable phone GPS support, especially on runs without a phone.

Pace tracking suffered when outdoor run distance came up short, with Wareable noting pacing was off too.

Pace tracking was limited by the lack of built-in GPS, with reviewers warning against expecting truly accurate phone-free pace data.

Comfort was generally good thanks to the light, unobtrusive body, though one comparison found it merely similar to the standard Band 9.

Comfort was a major strength, with most reviewers calling the Fit3 light and easy to wear, though a few disliked strap pressure or fit.

Fit was positive in the long-term review, where the band did not get in the way or restrict wrist movement.

Fit was criticized in one review because putting it on and removing it squeezed the strap against the skin.

Build quality was polarized, with some reviewers criticizing the cheaper plastic feel and another saying the materials felt premium.

Build quality was praised for a well-made feel and robust aluminum body.

Durability was mixed: the case and reinforced glass handled bumps and wear well, but one long-term reviewer had the original strap snap.

Durability was generally positive, with water resistance and months of use without visible damage, though scratches were possible.

Design and appearance were generally simple and functional, with one reviewer calling the matte black design great and another noting basic plastic compromises.

Design and appearance were strongly positive, with reviewers calling it handsome, elegant, premium-looking, or attractive.

Water resistance received positive evidence from GSMArena, which considered it suitable for the pool and shower.

Water resistance was praised for peace of mind when swimming and showering.

Band quality was mixed, from premium-feeling materials in one review to a less sleek strap and a snapped original strap in others.

Band quality was mixed, with good silicone feel in several reviews but frustration around proprietary strap options.

Battery life was the strongest consensus win, praised across nearly every review even when 18 days was called optimistic under heavier use.

Battery life was widely praised as better than most smartwatches, but real-world results varied from about two days with heavy always-on use to a week or more.

Charging convenience was a recurring complaint because reviewers found the magnetic cable did not lock or stick securely enough.

Charging convenience was mixed because the proprietary cable was sometimes useful but also criticized as custom, dated, or unreliable.

Charging speed was mixed: some accepted the roughly two-hour refill, while others called 90 to 120 minutes slow.

Charging speed was mixed: several reviewers found charging fast, while others found it slow or merely average.

Display quality was divisive: several reviews criticized the TFT panel as dull or mediocre, while others praised sharp, bright visuals for the price.

Display quality was one of the strongest themes, with reviewers praising the AMOLED panel, size, clarity, and vividness.

Screen brightness was mixed overall, ranging from fine or effectively optimized to noticeably lower than Xiaomi's AMOLED bands.

Screen brightness was generally positive, especially auto-brightness and raise-to-wake, though outdoor brightness was not perfect in every review.

Outdoor visibility was positive in two reviews, which found the display usable or easily visible in direct sunlight.

Outdoor visibility was mostly good, with repeated praise for bright sunlight readability, but a few reviewers said direct sun could be weaker.

Overall reliability was mixed: TechRadar found it hard to recommend, while a long-term user described it as part of daily life.

Reliability was mixed because some reviewers saw stable daily use while others found firmware instability or lower reliability than Samsung watches.

Data syncing reliability was strong in the two reviews that mentioned it, with no setup, sync, or data interruption problems.

Data syncing reliability was a real concern in one review because sync failures caused data loss.

Value for money was strong but conditional: many reviewers praised the low price, while some argued the standard Smart Band 9 is worth paying more for.

Value for money was the strongest consensus: reviewers repeatedly called it brilliant, affordable, or a strong bargain.

Button controls were a weakness because GSMArena was not convinced the all-swipe approach was best, especially with wet hands.

Button controls were simple and functional, with one reviewer appreciating the single-button return behavior.

App alerts worked with some friction, as GSMArena reported minor delays in incoming notifications.

App alerts were part of the positively described notification mirroring package.

Touch responsiveness was split, with lag and extra swipes in some testing but a very fluid, snappy feel in another review.

Touchscreen responsiveness was widely praised as accurate, fluid, and responsive, with only occasional lag or ASR-noted roughness.

Music controls were mixed: they worked and were liked in two reviews, but Wareable said they failed completely in testing.

Music controls were useful for controlling phone playback from the band.

Smartphone notifications were functional but basic: reviews praised quick wrist alerts while also noting no reply support.

Smartphone notifications were a strength, with instant notifications, syncing, and comprehensive mirroring mentioned positively.

The companion app was mostly viewed positively for depth, trend summaries, and easy navigation, though one review found presentation less clean.

Companion app quality was a strength, especially Samsung Health and Galaxy Wearable for clear data, setup, and customization.

Customization was a strength through straps, faces, and layout options, though some watch-face and widget customization remained limited.

Customization options were praised for easy strap or visual customization.

Watch face options were broadly praised for quantity and free choices, with caveats about onboard storage and limited customization.

Breathing exercises had mixed evidence: CGMagazine treated the health tools as handy, while one YouTube reviewer missed Breathing and Focus on the Active.

Breathing exercises were described as useful for regaining balance during stress.

The alarm function earned strong praise from the long-term reviewer, who called the silent vibration alarm a favorite feature.

The alarm function was considered useful, especially with customizable vibration alerts.

Health trend insights were supported by GSMArena's praise for the app's rich health, sleep, and activity trend summaries.

Health insights were praised through Samsung Health’s engaging advice and data presentation.

Weight was a clear positive, with reviewers describing the band as barely noticeable and ultra-lightweight.

Weight was praised repeatedly; reviewers liked the light body for sleep and all-day wear.

Text alerts were limited by read-only handling; messages can appear on the band, but reviewers noted replies are not supported.

Text alerts were workable through canned responses, but the experience was not ideal.

Readiness-style scoring was weak in the evidence; one reviewer missed the Vitality Score and related training functions on the Active model.

The lack of a fuller readiness or energy score was noticed as a drawback compared with higher-end wearables.

The stopwatch had one positive practical mention as useful for PE teachers or other timing situations.

The stopwatch was explicitly called useful.
