Compare Xiaomi Redmi Watch 5 vs Apple Watch Ultra 2

Auto-detection is present and useful for walking-style activity prompts, but the evidence also notes limited customization around how it detects workouts.

Automatic activity support appears around brisk-walk logging, running-track recognition, and contextual auto-marking, though reviewers do not dwell on broad workout auto-detection.

The app ecosystem is limited: reviewers describe basic smarts, some data sharing, but no broad third-party app store or richer platform-level features.

The app ecosystem is one of the clearest strengths, with reviewers praising Apple’s native and third-party app depth over competing watch platforms.

Band feedback is mostly positive for comfort, quick-release swapping, and optional straps, though one reviewer found the stock strap unremarkable and another disliked the proprietary system.

Band impressions are mostly positive, especially for comfort and material quality, though one reviewer found the Alpine Loop slow to dry after sweat or water.

Battery life is one of the strongest themes, with reviewers repeatedly reporting multi-day to multi-week endurance, although heavy tracking and always-on use shorten it significantly.

Battery life is excellent for an Apple Watch, often lasting two to three days, but dedicated GPS watches still make it look short for endurance use.

Blood oxygen tracking is widely present, including continuous or overnight options in several reviews, but it is treated as a wellness metric rather than medical-grade data.

Blood oxygen coverage is mixed in the review set because some reviews mention the feature’s patent-related absence, while the updated PCMag review says monitoring was restored.

Bluetooth connectivity supports calls, phone-linked GPS assistance, notifications, and music-related functions, but one reviewer notes the watch cannot connect extra Bluetooth peripherals.

Bluetooth support is strong for cycling accessories, especially power meters, speed sensors, and cadence sensors, with reviewers treating it as a useful sports upgrade.

Brightness is a clear strength, with many reviewers highlighting the 1,500-nit AMOLED screen and strong automatic brightness behavior.

Brightness is a major consensus strength, with repeated praise for the 3,000-nit display and flashlight improvement.

Build quality is generally praised for feeling better than a cheap smartwatch, with aluminum construction mentioned often, though some plastic elements remain.

Reviewers consistently describe the build as premium, rugged, and performance-oriented, with titanium, sapphire, and protected controls adding confidence.

The rotating crown is generally useful, tactile, and easy for navigation, but reviewers note the lack of extra buttons or more advanced shortcut controls.

Button controls are a practical Ultra advantage, especially the Action Button and gloved-use crown, though one long-term reviewer admits the Action Button never became a habit.

Call handling is consistently usable over Bluetooth, with several reviewers praising clear enough microphones and speakers while a few describe limited loudness or clarity.

Call handling gets direct praise for clear and sufficiently loud audio, helped by the Ultra line’s microphone and speaker hardware.

Calorie tracking appears as part of the broader activity and rings system, useful for basic motivation rather than advanced nutrition or training analysis.

Calorie tracking is framed through Apple’s activity rings and standard fitness metrics rather than as a lab-tested calorie measurement system.

Charging convenience is mixed: the magnetic/pogo-pin charger attaches securely and can be shared with some Xiaomi devices, but reviewers dislike the proprietary cable and slow Bluetooth file-transfer context.

Charging is convenient through familiar magnetic charging and occasional iPhone-powered charging, though reviewers still need to charge more often than with sports watches.

Charging speed ranges from good to merely reasonable, with reports of around 60 to 80 minutes in some reviews and roughly two hours in another.

Charging speed is acceptable, commonly around 0-80% in about an hour and full in roughly 90 minutes, but slower than the faster-charging Series 10.

Coaching features are better than expected for a budget watch, including running courses, AI pacer-style workout tools, breathing guidance, and some sleep suggestions, but not personalized advanced coaching.

Coaching improved with Training Load and effort context, but several reviewers still find Apple’s coaching and analysis shallower than Garmin, Whoop, or similar platforms.

Comfort is a major positive because the watch is light, wearable overnight, and easy to forget on the wrist despite the large display.

Comfort is context-dependent: some reviewers find the Ultra 2 comfortable all day, while others note size, tugging, or crown irritation on smaller wrists.

The Mi Fitness companion app is generally clean, visual, and easy to use, but some reviewers call it basic and not as advanced as higher-end ecosystems.

Companion app quality is strong, with reviewers praising Apple Watch, Health, and Fitness app integration and easy configuration from the iPhone.

Contactless payment support is absent in the global model according to multiple reviews, making this a clear limitation.

Contactless payments are a reliable smartwatch strength, with Apple Pay repeatedly cited as part of the platform’s everyday convenience.

Cross-platform compatibility is strong for basic use, with reviewers confirming Android and iOS support, though some features vary by phone platform.

Cross-platform compatibility is poor because the Ultra 2 requires an iPhone and does not work with Android phones.

Customization is good for budget use, especially watch faces, widgets, launcher layout, and some personal photos, but deeper watch-face customization is limited.

Customization is strong across watch faces, complications, utility slots, action button choices, and app-driven personalization.

Display quality is one of the watch's strongest attributes, with reviewers praising the large AMOLED panel, sharpness, color, responsiveness, and premium feel for the price.

Display quality is one of the best-reviewed attributes, with multiple reviewers calling it among the best smartwatch screens they have tested.

Durability looks decent for the price, with reviewers citing scratch-free use and rugged-enough construction, though dust protection and premium glass are not emphasized.

Durability is a major strength, supported by titanium, sapphire, MIL-STD testing, and reviewers’ reports of wear resistance.

ECG functionality is not available, with reviewers explicitly saying there is no ECG option.

ECG functionality is well supported and repeatedly mentioned as part of the Ultra 2’s robust health suite, including Afib-related features.

Fit is mixed: the watch is light and straps cover a broad wrist range, but the single large size can feel overwhelming on smaller wrists.

Fit is mixed: the rectangular case can feel secure, but the single 49mm size can be challenging for smaller wrists.

Fitness tracking accuracy is mixed: some reviewers found it effective or strong for casual tracking, while others called it less precise than dedicated sports watches.

Fitness tracking accuracy is excellent overall, with reviewers praising GPS, heart-rate, and overall workout tracking accuracy against reference devices.

GPS accuracy is split across reviews, ranging from accurate and reliable for casual runs to overreported distances and slight running inaccuracies.

GPS accuracy is consistently strong, with dual-frequency/multiband tracking matching or approaching Garmin-class performance in several tests.

Health tracking accuracy is adequate for basic wellness but not advanced or medical-grade, with reviewers noting decent data alongside sensor limitations.

Health tracking accuracy is viewed positively for sleep apnea, ECG-adjacent accuracy, and broad health tracking, though some insights still need manual interpretation.

Heart rate accuracy is inconsistent: some tests found close results against chest straps, while others saw high readings, lag, or occasional anomalies.

Heart-rate accuracy is one of the strongest measured areas, with reviewers reporting close agreement with chest straps and armband monitors.

LTE connectivity is absent on the global model, with several reviewers specifically noting no LTE or eSIM support.

LTE is a core feature because cellular support comes standard, enabling calls, streaming, and messaging away from the iPhone when a plan is active.

Mapping and navigation are useful but frequently caveated: Compass, waypoints, routes, and maps help, yet native GPX and phone-free offline mapping gaps remain.

Materials quality is better than many budget watches thanks to aluminum alloy, but reviewers still mention plastic or plasticky elements.

Materials quality is high, with recycled titanium, sapphire protection, and premium band hardware recurring across reviews.

Menu navigation is easy overall, helped by the rotating crown, app grid/list options, and stacked widget layout.

Menu navigation is helped by the crown, complications, Modular Ultra, and Smart Stack, which reviewers generally find useful for quick glanceable information.

Music controls are useful for controlling phone playback, and several reviews note accessible media controls from the watch.

Music controls work well through Double Tap and the Music app, with speaker playback and wrist controls adding everyday convenience.

Onboard music storage exists and is useful for phone-free workouts on supported setups, but storage and transfer behavior are limited.

Onboard storage is improved to 64GB, giving reviewers more confidence for offline music, podcasts, apps, and media downloads.

The operating system experience is lightweight and mostly pleasant, but reviewers repeatedly cite proprietary HyperOS limitations versus Wear OS or watchOS.

The operating system experience is polished, especially with watchOS 10 and 11 updates adding new watch faces, cycling features, Smart Stack, and Ultra features.

Outdoor visibility is excellent across reviews thanks to the bright AMOLED display and readable screen in direct sunlight.

Outdoor visibility is excellent, with several reviewers reporting no trouble reading the screen in sunlight or bright reflective conditions.

Pairing reliability is strong where discussed, with reviewers reporting no pairing or syncing issues and quick satellite/connection readiness.

Pairing evidence is limited but positive, with one setup transcript saying the familiar Apple pairing flow completed cleanly.

Recovery insights are present through training status, recovery time, breathing, and workout-load style metrics, though they remain basic.

Recovery insights are a recurring weakness; reviewers repeatedly say Apple lacks Garmin/Whoop-style recovery, readiness, and performance analysis.

Reliability is generally good in day-to-day use where cited, with raise-to-wake, smoothness, and connection stability praised.

Reliability is broadly positive in long-term and battery-use impressions, with reviewers describing stable every-other-day charging and dependable use.

Safety features are limited but include an SOS option that can call an emergency contact through the connected phone.

Safety features are a standout Ultra trait, including siren, SOS, fall and crash detection, Backtrack, cellular waypoints, and emergency guidance.

Size options are weak because the watch comes in one large size, which one reviewer said will not suit every wrist.

Size options are a clear limitation because the Ultra 2 comes only in a large 49mm case.

Sleep tracking accuracy is mixed: some reviewers found duration and broad stages close, while others saw inconsistent results or deep-sleep overestimation.

Sleep tracking is generally accurate but simpler than rival platforms; newer sleep apnea detection adds more health value.

Smartphone notifications are one of the clearest compromises: mirroring works, but replies, emojis, pictures, and actionable notifications are limited or missing.

Smartphone notifications are handled well, with reviewers praising rich notifications, texting, and responsive notification handling within the Apple ecosystem.

Smartwatch features cover the basics well, including notifications, calls, alarms, timers, and basic apps, but remain limited versus premium smartwatches.

Smartwatch features are outstanding overall, with reviewers treating the Ultra 2 as Apple’s most full-featured wearable and a top true smartwatch.

Software smoothness is mostly good, with some reviews calling it smooth and others noticing stutters, touch lag, or less-than-60Hz-feeling animations.

Software smoothness is strong, with reviewers describing zippy, quick, responsive, and buttery-smooth operation.

Step counting accuracy has limited direct evidence, but the detailed review found exercise-mode step counting nearly dead-on and daily counts generally close.

Stress tracking is widely included, but reviews treat it as a basic wellness feature and one reviewer found it slow and sensitive to movement.

Style and design are broadly attractive and modern, but several reviewers point out obvious Apple Watch influence or lack of originality.

Style and design are praised for the premium rugged look, especially the black titanium version, though the large look is not for everyone.

Third-party app support is poor, with no native Spotify or YouTube Music support, few extra apps, and one reviewer saying no third-party apps are available.

Third-party app support is excellent through the watchOS App Store and helps fill gaps in navigation, fitness, and everyday smartwatch use.

Touchscreen responsiveness is mostly good, including wet-use and swipe/tap responsiveness, though one reviewer found touch lag in parts of the software.

Touchscreen responsiveness is excellent on land, with reviewers praising taps and swipes, though touch does not work underwater.

The user interface is generally approachable, smooth, and pleasant, with reviewer praise for simplicity and navigation despite some platform limitations.

The user interface is generally easy and polished, especially for iPhone users, Smart Stack, and redesigned watchOS apps.

Value for money is strongly positive overall because reviewers praise the display, battery, and basic features for the price, though one reviewer considered it overpriced against cheaper alternatives.

Value is mixed: the Ultra 2 can justify its price for users who exploit its rugged, cellular, and battery advantages, but reviewers repeatedly note cheaper or more specialized alternatives.

Voice assistant quality scores poorly because reviewers state that Alexa or other voice assistant support is absent.

Voice assistant quality improved with on-device Siri, faster commands, better dictation, and less cloud dependence, though a few minor voice quirks remain.

Watch face quality is a strength, with many free, attractive, and varied faces, although customization depth differs by face.

Watch face quality is strong, especially Modular Ultra and complication-rich layouts designed for the large screen.

Water resistance is consistently supported, with 5ATM ratings and swimming or shower use reported, though hot-water and diving caveats remain.

Water resistance is a major strength, with 100m/WR100 ratings, diving support, and better water credentials than standard Apple Watches.

Wellness insights include sleep suggestions, Vitality Score, and basic health summaries, but reviewers note limited personalization or AI-style guidance.

Wellness insights are broad but uneven: Vitals, Health data, and trends help, but reviewers often want more interpretation and readiness-style guidance.

Wi-Fi connectivity is absent, specifically called out as a limitation for faster file transfers or standalone connectivity.

Wi-Fi is present as part of the core connectivity package, though reviews discuss it mostly as availability rather than as a tested performance differentiator.

Workout variety is excellent for the category, with reviewers repeatedly citing more than 150 sports modes and broad activity coverage.

Workout tracking variety is strong across running, cycling, hiking, swimming, diving, strength training, structured workouts, and third-party sport apps.
