Compare Xiaomi Redmi Watch 4 vs Garmin Approach S50

Workout auto-detection appears in several reviews and covers common modes, so it is a useful convenience rather than a standout training feature.

Auto-detection evidence is strongest around golf-shot detection, score prompts, and Move IQ-style automatic activity interpretation.

The watch handles built-in basics, but reviewers repeatedly note that there is no real app store or downloadable app ecosystem.

The Garmin ecosystem is a strength, especially app syncing, accessory support, Garmin Golf membership upgrades, club sensors, and cross-device benefits.

Strap feedback is split: quick-release hardware is welcomed, but several reviewers criticize the clasp, feel, or friction of the stock band.

Band quality is polarizing: several reviewers liked the lightweight nylon ComfortFit band, while others found it fiddly, sweaty, or less premium.

Battery life is one of the clearest strengths, with reviewers commonly getting a week or more and quoting up to two or three weeks depending on settings.

Battery life is strong overall, with multi-day to near-week-long use reported, but it remains below the S70's rated endurance.

Blood oxygen tracking is present and can run continuously, but reviewers disagree on whether the readings are dependable enough for deeper health insight.

Blood oxygen tracking is present through Pulse Ox, with reviewers noting both the sensor and sleep/on-demand measurement behavior.

Bluetooth is adequate for pairing and calls, with reviewers treating it as a basic but functional connection layer.

Bluetooth connectivity is useful for accessories, especially rangefinder yardages and connected golf hardware.

Brightness is consistently praised, with the 600-nit AMOLED panel considered strong for the price and usable in bright conditions.

Brightness is generally praised, but one Florida-sun review found smaller text could be hard to read in direct sunlight.

Build quality is a major upgrade over prior Redmi watches thanks to the aluminum/metal frame and generally sturdy feel.

Build quality is generally positive for slimness and lightness, but one reviewer felt the S50 was somewhat plasticky versus pricier models.

The rotating crown is useful for navigation, though some reviewers dislike its lack of tactility or note accidental presses.

Button controls are functional with two side buttons, but several reviewers preferred the extra physical controls on higher-end Garmin watches.

Bluetooth calling is consistently treated as a useful smartwatch feature, with positive comments about making, receiving, or hearing calls from the wrist.

Call handling is basic: reviewers found phone-call notifications and answer/reject controls, but no full calling experience from the watch.

Calorie tracking is only supported as a rough estimate, not a reliable training metric.

Calorie tracking is available as part of the daily health metrics, but reviewers mostly mentioned it as a tracked stat rather than deeply evaluating its usefulness.

Charging convenience is limited because reviewers identify the cable as proprietary, making it less travel-friendly than universal charging.

Charging convenience is mixed: the cable is familiar for Garmin users, but proprietary charging was criticized as inconvenient for trips.

Charging speed is not a strength; one review specifically notes there is no fast charging and a full charge takes well over an hour.

Charging speed has limited evidence, but one reviewer said the initial charge only took a few hours.

Coaching features are better than expected for the price, with running workouts, warm-ups, and training details, but they remain basic.

Coaching features include Garmin coaching, meditation or breathing prompts, sleep coach, and training-program support, though they are secondary to the golf feature set.

The large watch is still light enough for all-day wear and sleep tracking, though its size can affect smaller wrists.

Comfort is one of the S50's standout strengths thanks to its lightweight, low-profile design, though the nylon strap can feel less comfortable when sweaty.

Mi Fitness is functional and covers settings and stats, but reviewers describe it as plain, dated, or merely adequate rather than polished.

The companion app experience is positive, with reviewers citing Garmin Golf setup, connectivity, and flawless syncing after pairing.

Contactless payment support is a repeated limitation outside China, with several reviewers saying payment/NFC functionality is missing or region-bound.

Contactless payments are supported through Garmin Pay/NFC, but reviewer evidence points to limited bank compatibility in the UK.

The watch is broadly compatible with Android and iOS, and reviewers reported using or setting it up across both platforms.

Cross-platform compatibility is mixed: the S50 works with iPhone and Apple users, but reviewers found Garmin's iPhone experience less flexible than Apple Watch integration.

Customization is decent for watch faces, widgets, shortcuts, straps, and personal photos, though some reviewers want deeper software customization.

Customization is strong for golf settings, data screens, flag position, watch upgrades, and optional feature toggles.

The large AMOLED display is one of the strongest features, though one reviewer found colors slightly washed out and bezels can be noticeable.

Display quality is a major strength, with repeated praise for the AMOLED/OLED screen, crispness, color, and modern look.

Durability looks good from the aluminum body and water resistance, but sharp-edge scratch concerns appear in one review.

Durability evidence is limited but positive, centered on the Corning Gorilla Glass 3 lens.

Fit is context-dependent because the large case helps readability but may feel oversized on smaller wrists.

Fit is strong for many wrists due to the low profile and adjustable fabric strap, though some reviewers questioned larger-wrist suitability.

Fitness accuracy is mixed: some reviewers praise it for casual use, while others find it too rough for serious training.

Fitness tracking accuracy is more mixed: reviewers liked the broad activity tracking and stats, but one noted the S50 cannot track elevation as accurately as the S70.

GPS feedback ranges from stellar to merely okay, with multiple reviewers saying competitors or phones can track more accurately.

GPS accuracy was one of the strongest points, with reviewers reporting quick satellite lock, reliable course selection, and yardages within a few yards of a laser rangefinder.

Overall health accuracy is mixed to weak because richer health metrics are undermined by questionable heart-rate and blood-oxygen data.

Reviewers treated the S50 as a credible health tracker, especially through body battery, HRV, blood oxygen, sleep, and daily activity insights, though the evidence is stronger on feature coverage than lab-level validation.

Heart-rate accuracy is the most disputed health metric, with several reviewers reporting poor or iffy readings and one positive reviewer seeing good reference data.

Heart-rate tracking was repeatedly cited as the key hardware difference that unlocks the S50's health and fitness value, with one reviewer noting it uses Garmin's older Gen 4 sensor.

LTE or cellular independence is absent, so connected features like SOS and assistant use still depend on a nearby phone.

Mapping and navigation are core strengths for yardages, hazards, green views, PinPointer, and course data, but fuller maps and green contours often require Garmin's paid membership.

Materials quality is widely praised for the aluminum or metal frame, which makes the watch feel less budget than older plastic models.

Materials are mixed-to-good, with Gorilla Glass and aluminum noted positively while the lightweight body drew a plasticky caveat.

Menu navigation is generally easy thanks to swipes, widgets, and the crown, with the large screen helping readability.

Menu navigation is mostly straightforward once learned, though one reviewer found the golf features a bit complicated at first.

Music controls are useful for phone playback, but reviewers do not describe true onboard music playback as a strength.

Music controls are present and useful, including phone music control and a music-controller feature in the watch interface.

Onboard music storage is effectively absent in the reviewed evidence; one review lists a music player among missing features.

Onboard music storage is available, but storage is modest compared with the S70 and one review specifically called out the 4 GB limit.

HyperOS is smooth but basic, and one Chinese-version review disputes whether it behaves like a real HyperOS smartwatch.

The operating-system experience is familiar and Garmin-consistent, but reviewers still saw some iPhone-related limitations.

Outdoor visibility is strong, with repeated praise for the bright screen being readable outside or in sunlight.

Outdoor visibility is mostly strong thanks to the bright AMOLED screen and big-number options, but direct sun can make fine details harder to see.

Pairing and syncing appear generally reliable in the main written review, though this is not heavily discussed across sources.

Pairing reliability is a strength, with reviewers describing Garmin Golf app pairing as simple, seamless, and reliable after setup.

Recovery insights exist, but reviewers question their usefulness because they rely on imperfect exercise and heart-rate data.

Recovery insights were supported by body battery, sleep-recovery feedback, and post-exercise recovery guidance, making this one of the stronger wellness features.

Reliability is mixed: one reviewer reports a recurring DND sync bug, while another praises good connection.

Reliability is strong, with reviewers saying Garmin golf watches simply work, though one review mentioned a reduced GPS-signal course issue.

Safety features center on emergency SOS through the crown, but reviewers note the phone must be nearby.

Safety features are present through LiveTrack and fall/emergency-contact settings, but they were covered mainly in a feature walkthrough.

Size options are limited compared with the S70, and reviewers repeatedly flagged that the S50 may feel small for larger wrists.

Sleep tracking is often good for bedtime and duration, but more advanced sleep or heart-rate details are less trustworthy.

Sleep tracking drew strong praise across reviews, with reviewers highlighting detailed scoring, sleep coach features, and comfort for overnight wear.

Notifications are useful and readable on the large screen, but reply support, emoji display, or notification limits are recurring caveats.

Smartphone notifications are useful for triage and can be muted in golf mode, but reviewers noted limited iPhone notification controls and limited actionability from the watch.

Smartwatch features cover basics like calls, notifications, weather, calendars, and controls, but reviewers repeatedly frame them as basic.

Smartwatch features are solid for a golf-focused device, adding alarms, timers, health metrics, notifications, weather, calendar, and broader daily-use tools.

Software smoothness is a standout; reviewers repeatedly call the interface smooth, snappy, fluid, or minimally laggy.

Software smoothness scored well based on seamless Garmin app pairing and the reviewer's statement that it works flawlessly after initial setup.

Step tracking is good enough for casual use, with reviewers finding it generally in line or not wildly off.

Stress tracking is included and can run with other wellness metrics, though reviews provide limited proof of its accuracy.

Stress tracking appeared consistently as part of the S50's wellness package, often tied to body battery, sleep, and heart-rate-based insights.

Reviewers generally like the design, especially the big square look and more premium metal frame at a budget price.

Style and design are widely praised, with reviewers calling the S50 sleek, lightweight, understated, and better looking than bulkier alternatives.

Third-party support is mixed: there is no watch app store, but Mi Fitness can sync with services like Strava and Apple Health.

Third-party app support is limited and mixed, with restrictions around iPhone app notifications but some music-provider support.

Touch and interaction responsiveness are positive where discussed, with reviewers calling the display responsive and the interface snappy.

Touchscreen responsiveness is a repeated strength, with reviewers calling the screen responsive, intuitive, and central to navigation.

The UI is generally clear, colorful, and optimized for the large square screen.

The interface is generally intuitive, with reviewers praising the touchscreen, simple golf start flow, and easy feature-to-feature movement.

Value is strong for shoppers prioritizing battery, display, and design, but several reviewers say rival budget watches can offer smarter features or better tracking.

Value depends on buyer priorities: reviewers liked the golf-plus-health package, but subscription-locked maps and the cheaper S44 created meaningful tradeoffs.

Voice assistant support is inconsistent: Alexa or Mi AI appears in some versions, while other reviewers note no assistant or China-only limitations.

Voice assistant support is weak, with the reviewer specifically noting that Siri-style talking from the watch is not available.

Watch faces are polarizing, ranging from limited and boring to a large free selection depending on version, region, and reviewer expectations.

Watch-face quality is decent with many selectable faces, though the S70 was described as having better customization options.

Water resistance is consistently strong for the category, with 5ATM/50m claims and real swim or shower use noted.

Water-related evidence is indirect: reviewers discussed swimming and shower use, but mainly as a nylon-band drying consideration.

Wellness insights are broad for the price, including sleep animals, Vitality, training load, and scores, but accuracy limits reduce trust.

Wellness insights are a major strength, especially body battery, sleep, stress, respiration, recovery, and health snapshots that make the watch useful off the course.

Wi-Fi support is present for updates, though reviewer evidence is limited to feature walkthrough coverage.

Workout variety is excellent for the price, with reviewers repeatedly citing more than 150 sports or workout modes.

Workout variety is broad for a golf watch, with support called out for runs, rides, swims, gym sessions, and other sports, though reviewers still framed it below higher-end Garmin fitness watches.
