Compare Huawei Watch GT 6 Pro vs Samsung Galaxy Watch Ultra 2

Heart-rate accuracy was one of the strongest themes, with reviewers comparing it favorably to chest straps and trusted wearables.

Heart-rate tracking is often very strong during running and cardio, with several tests showing close agreement with Polar straps, Apple Watch and other references. Harder conditions such as strength work, swimming or cadence-heavy movement can still produce errors.

GPS accuracy was widely praised, including fast locks and precise routes, though one scientific review found it only decent with some odd traces.

Dual-band GPS is usually fast to lock and highly accurate, often matching Garmin or other reference devices closely on distance and route shape. Some tests still found corner cutting or small deviations, so it is excellent rather than perfect.

Sleep evidence was split: several reviewers praised insights and consistency, while YouTube testing found sleep stages weak or uncomfortable to capture.

Sleep tracking is one of the most inconsistent areas: some testers found stages and duration closely matched other wearables, while others saw missed periods or implausible scores. The comfort improvements make overnight wear easier, but the data itself is not uniformly dependable.

Fitness tracking accuracy was strongly praised across runs, cycling, gym sessions and scientific testing, with only minor caveats.

General exercise tracking is strong, with several controlled tests showing close agreement on distance, steps and body metrics. Accuracy is not flawless across every sport or metric, but the overall fitness-tracking performance is competitive.

Coaching and cycling-power features were useful but mixed: reviewers liked the idea, yet several said estimates should not replace dedicated meters.

Samsung’s running, fitness and health coaching can turn scores into personalized goals and suggested workouts, and several users found it genuinely helpful. Pacing errors, calibration requirements and some iFIT-linked workouts keep the experience from feeling universally polished.

Workout variety was consistently positive, with reviewers noting broad sport modes and meaningful data for running, cycling, skiing, golf and more.

The Ultra 2 offers a very broad workout library plus new trail-running and diving tools, making it versatile for general fitness and outdoor use. Serious athletes still note missing modes and deeper sport-specific features, so breadth does not always equal depth.

Recovery insights received limited but positive support from one reviewer who specifically liked Huawei’s post-workout recovery measurements.

Energy Score, Cardio Load and related recovery tools can help decide whether to push harder or back off, and several users found the guidance useful. Some advice can feel generic, stale or less sophisticated than Garmin, Oura or Google alternatives.

Step counting received limited but positive evidence, with reviewers calling counts consistent or more accurate than older Huawei devices.

Step accuracy is sharply mixed. Manual walking tests can be nearly exact, but multiple sources reported phantom steps while driving and one test produced a dramatically inflated count.

Reviewers generally found the health suite broad and accurate, though one early CNET impression had not tested it yet.

Health measurements are broadly credible, with some metrics aligning closely with scales or other wearables. There are also reports of missed readings, questionable outliers and body-composition bias, so not every metric deserves equal confidence.

Blood oxygen readings were treated positively where tested, staying within acceptable ranges or grouped with accurate sensor results.

Blood-oxygen tracking is described as working normally alongside the watch’s other core health sensors. There is little standalone testing of SpO2 accuracy, so confidence is more limited than for heart rate or GPS.

Wellness insights were a major strength, with reviewers praising clear explanations, health summaries and actionable trend-based guidance.

Samsung’s Vitals, Heart Health Score, Cardio Load and other wellness tools are widely praised for turning raw sensor data into understandable trends and prompts. Some features need a week or more of baseline data, but the overall health context is a major strength.

Stress and emotional tracking drew moderate-to-positive reactions, but some reviewers found mood interpretation woolly or uncertain.

Stress tracking is reported to work normally alongside Samsung’s other core health measurements. There is little dedicated testing of the stress metric itself, so the positive signal is limited.

Battery life was the strongest consensus point, with every review praising multi-day or multi-week endurance.

Battery life is one of the Ultra 2’s biggest upgrades, commonly landing around two to three days and sometimes longer depending on settings and GPS use. Heavy navigation and workouts cut that endurance, but most users no longer need to plan around daily charging.

Charging convenience was mixed, with useful top-ups but criticism of older connectors or proprietary charging.

Charging convenience is a recurring weakness because the Ultra 2 relies on Samsung-compatible magnetic charging and often refuses standard Qi or third-party multi-device stands. That makes travel and bedside setups less flexible than the watch’s premium price suggests.

Charging speed was acceptable but not standout; reviewers often excused slower charging because battery life is so long.

Charging speed is inconsistent across testing: some units reach useful top-ups or a full charge in roughly 90 minutes, while others take closer to two hours or initially far longer. Even positive testers often wish the large battery refilled faster.

Comfort was mostly good despite the large case, though bulk was a caveat for some wrists.

The thinner case and softer bands make the Ultra 2 dramatically easier to wear than the first model, and many testers could comfortably keep it on overnight. Its 47mm body is still large and can feel cumbersome on smaller wrists or for sensitive sleepers.

Materials were a major strength, with repeated praise for titanium, sapphire glass, ceramic and robust finishes.

Titanium and sapphire give the Ultra 2 a distinctly premium, durable feel. The materials are tough and corrosion-resistant, though the titanium case can still pick up cosmetic marks over time.

Size options were a weakness because the Pro only comes in 46mm, which several reviewers said may be too big for smaller wrists.

The single 47mm case is a repeated complaint. Even with the thinner design, buyers with smaller wrists have no compact Ultra option and may be better served by the standard Galaxy Watch line.

Water resistance was generally positive for swimming, diving or wet use, though one scientific reviewer treated it as swimproof rather than diveproof.

Water durability is exceptional, with 10ATM, IP69K and EN13319 diving certification giving the Ultra 2 much stronger aquatic credentials than a normal smartwatch. Several testers view it as legitimately dive-ready rather than merely swim-safe.

Band quality was mixed-to-positive: some straps were soft and attractive, while one reviewer disliked the brown strap.

Samsung’s redesigned bands are generally softer, lighter, more flexible and more breathable than the first Ultra’s straps, making long wear and sleep easier. The proprietary attachment and high accessory pricing remain notable drawbacks, and one Marine Band was still found rough.

Build quality was consistently praised as premium, solid and excellent.

The titanium construction feels solid, premium and cohesive, with a case that looks and feels appropriate for a flagship outdoor watch. The hardware is repeatedly described as exceptionally well put together.

Durability was praised for scratch resistance, rugged materials and outdoor toughness, with only one sponsored claim-style mention.

Titanium, sapphire crystal, IP69K protection, 10ATM water resistance and military-grade testing make the Ultra 2 exceptionally rugged. It handles daily knocks confidently, although exposed case edges can still collect cosmetic scratches.

Fit was acceptable overall, but reviewers noted the watch can feel hefty or large.

The slimmer body, flatter stance and secure band system improve how the Ultra 2 sits on the wrist. Fit is still highly wrist-dependent because the single 47mm case can overwhelm smaller wrists despite the comfort gains.

Style and design were widely praised, with reviewers calling it premium, refined, stylish and suitable for both workouts and formal settings.

The squircle-and-circle design is polarizing in theory but wins over many users in practice, especially with the slimmer profile, engraved bezel and premium finishes. A few details, such as the orange center button or sheer size, still divide opinion.

Display quality was a standout strength, with reviewers praising sharpness, color, size and overall AMOLED quality.

The Super AMOLED display is a standout strength, repeatedly praised for sharp text, vibrant color, excellent contrast and generous screen space. Several testers called it among the best smartwatch displays they have used.

Outdoor visibility was one of the clearest strengths, with many reviewers saying the screen stayed readable in direct sunlight.

Outdoor readability is close to unanimous praise. The 5,000-nit display remains clear in direct sun, on trails and even around water, making workout data and navigation easy to glance at without shading the screen.

Brightness was excellent outdoors, though one reviewer noted the minimum brightness could still be too high in dark environments.

The 5,000-nit panel is consistently praised as exceptionally bright, even if some consider that level more than most situations require. Its extra headroom becomes genuinely useful in harsh sun and for the screen-based flashlight.

Reliability had limited negative evidence, mainly software bugs and missed notifications.

A small but important set of tests found intermittent gaps in heart-rate or sleep data even when the watch was worn consistently. Those misses make sensor reliability a concern for buyers who depend on uninterrupted health records.

Value was broadly positive, with reviewers praising the price-to-materials, battery and fitness package despite ecosystem compromises.

The $699 price produces the most divided opinions. The battery, display, durability and outdoor features can justify the premium for active users, but the Galaxy Watch 9 and discounted older Ultras deliver much of the everyday experience for less.

Voice assistant support was a clear weakness because reviewers noted no assistant or missed Google Assistant-style functionality.

Gemini is one of the Ultra 2’s most consistently praised smart features, especially for Raise to Talk, timers, questions and app actions without touching the screen. A few tests found the raise gesture inconsistent, but most found it fast and genuinely useful.

Third-party app support was weak, especially outside China, with reviewers noting limited integrations and reduced on-watch app usefulness.

Third-party app support is excellent for a smartwatch, with useful Wear OS options such as Spotify, Strava and WhatsApp working directly on the watch. This breadth is a major advantage over more closed fitness-watch platforms.

Contactless payments were a repeated pain point, mostly unavailable, region-limited or less appealing than Apple Pay and Google Pay.

Google Wallet and Samsung’s payment support make quick purchases from the wrist easy and genuinely phone-free. Testers who used it viewed payments as one of the practical everyday smartwatch benefits.

The app ecosystem was one of the most consistent complaints, with reviewers calling AppGallery small or the overall ecosystem limited.

Wear OS gives the Ultra 2 an unusually strong smartwatch app library, with Google Maps, Spotify, WhatsApp, Gmail, YouTube Music and other familiar tools working directly on the wrist. App availability is one of its clearest advantages over many dedicated sports watches.

Wi-Fi was weak, with reviewers noting no official Wi-Fi or contrasting the GT 6 Pro unfavorably with Huawei models that include it.

Wi-Fi is useful as a fallback when the phone is absent, allowing messaging and other connected functions without LTE. There is little direct testing of Wi-Fi performance beyond that use case.

Onboard music was mixed: one reviewer noted local track storage, while others missed offline Spotify or phone-free streaming.

The 64GB storage provides ample room for offline playlists, podcasts, maps and apps. It meaningfully improves phone-free runs because music can stay on the watch and play directly to Bluetooth earbuds.

Smartwatch features were limited overall: fitness and basics were solid, but reviewers said it was not a full smartwatch replacement.

As an everyday smartwatch, the Ultra 2 is exceptionally capable, covering calls, messages, payments, apps, music, LTE, AI and health tools without constant phone use. Even critical sports-focused testers generally agree that its core smartwatch experience is excellent.

Menu navigation was strong where mentioned, especially the crown and recent-app navigation.

Navigation is mixed: the digital bezel can feel intuitive and responsive, but several users still miss a physical rotating bezel for precision, gloves or wet hands. Touch-based scrolling can also obscure content or overshoot.

Pairing reliability was positive in the few tested cases, with reviewers describing easy iPhone pairing and reliable headphone or setup pairing.

Initial Samsung-phone setup can be clean and automatic, but connectivity is not flawless. One real-world run lost the phone connection and interrupted media playback, leaving this a limited and mixed area.

HarmonyOS was generally smooth and liked by reviewers, though it did not feel dramatically changed from earlier GT watches.

Wear OS 7 with One UI Watch 9 is powerful, polished and tightly integrated with Android, with a strong app library and long software-support promise. The overall OS experience is one of the watch’s strongest everyday advantages.

Mapping and navigation were mixed: offline maps and route views helped, but Petal Maps was repeatedly weaker than Google or Apple alternatives.

GPX routes, turn-by-turn guidance, off-route warnings and Google Maps make navigation genuinely useful for hikes and runs. Route loading, missing map labels, limited rerouting and the lack of a full always-available offline map system keep it behind dedicated outdoor watches.

Notifications worked for basic viewing, but reviewers criticized missed alerts, limited replies and weaker interaction than full smartwatch platforms.

Notification delivery has improved substantially and can be seamless once configured, with direct replies working well. Default app permissions and Samsung’s notification settings can still require manual cleanup and occasionally cause missed alerts.

Watch faces were a positive theme, with reviewers praising variety, paid/free options and colorful designs.

Samsung and the Play Store offer a large, attractive selection of watch faces with useful complications and strong customization. The bright, large display gives those faces plenty of room to work.

The companion app was mixed: some praised clear data and trend analysis, while others found setup fiddly or advanced settings chaotic.

Samsung Health is generally praised for clearer organization, useful health cards and an approachable amount of detail. It can still feel fragmented across multiple Samsung apps, and occasional lag, freezes or awkward organization appear in heavier use.

Music controls were useful for controlling phone playback, and one reviewer found them responsive and reliable.

Music control works well from the wrist, including full YouTube Music browsing and playback management. It is a useful part of the watch’s ability to replace short phone interactions.

Call handling was generally praised, with reviewers noting clear wrist calls, strong mic/speaker performance and convenient hands-free use.

Calls are a strong everyday feature: audio is loud enough to hear, the speaker is clear, and callers reported good microphone quality. The watch works well for quick phone-free conversations.

Customization evidence was limited but positive, mainly around customizable widgets and cards.

Watch faces, tiles, complications, gestures, shortcuts and swappable bands give the Ultra 2 extensive room for personalization. Proprietary band hardware is the main constraint in an otherwise flexible setup.

Software smoothness was praised, with reviewers calling animations fluid, menus responsive and everyday performance stutter-free.

The Snapdragon Wear Elite platform makes the interface, apps and animations fast and fluid in most testing, a clear improvement over older Galaxy watches. A few users still noticed stutters or heavier-app hiccups, so it is not perfectly consistent.

Touchscreen responsiveness was strong, with reviewers describing snappy response, smooth transitions and very good touch performance.

Touch input is generally fast and responsive, including the improved touch bezel. Wet or sweaty workout conditions still make physical controls preferable, but the touchscreen itself earns strong marks.

Button controls were highly rated, especially the rotating crown, tactile buttons, shortcuts and haptic feedback.

The Quick Button and side keys are generally tactile, responsive and useful for fast workout or shortcut access. Opinions are less positive about the missing rotating bezel, occasional button crowding and controls that can be awkward during sweaty workouts.

The interface was praised as simple, versatile and polished, with easy navigation through Huawei’s watch UI.

One UI Watch is usually intuitive, customizable and easy to learn, especially for existing Samsung users. Feature density and a few interaction choices can make some menus busier or more awkward than necessary.

Bluetooth evidence was limited but positive, with one reviewer saying headphone pairing was simple and reliable.

Bluetooth support is useful for phone-free audio and, notably, direct cycling power-meter connections. The connection options broaden the watch’s usefulness without requiring a phone for every activity.

Safety features were mixed: fall detection and SOS were appreciated, but false triggers and limited emergency behavior were concerns.

Emergency SOS, fall detection and the loud siren are repeatedly viewed as reassuring additions for outdoor use. They are features most owners hope never to need, but they strengthen the Ultra 2’s adventure credentials.

LTE was a weakness, with reviewers criticizing the lack of cellular support, especially at a premium price.

Built-in LTE can make the Ultra 2 genuinely independent for calls, messages and workouts without a phone, and cellular battery use has improved. The forced LTE configuration, lack of 5G, extra plan cost and battery drain make it unnecessary overhead for some buyers.

Cross-platform compatibility was broadly positive for iOS and Android support, though some reviewers still noted iPhone or ecosystem limitations.

Compatibility is one of the Ultra 2’s clearest limitations: it is Android-only, and ECG, blood pressure, sleep-apnea features and some integrations can require a Galaxy phone. Other Android phones still get much of the experience, but not the complete feature set.

Flashlight usefulness had limited but positive support from one reviewer who called out torch mode as handy.

The screen-based flashlight benefits directly from the very bright display and is surprisingly useful for dark rooms, nighttime checks and quick tasks. It cannot match a dedicated hardware flashlight, but it is far from a throwaway feature.

Auto-detection was mixed: cycling and activity recognition could be handy, but some reviewers found workout detection slow or hit-and-miss.

Automatic workout recognition is usually quick and dependable, with several testers praising reliable starts and responsive pausing. A few sessions were split after longer stops, so manual starts are still safer when one continuous track matters.

ECG was viewed as useful and easy enough to access, though some evidence focused on availability and reporting rather than medical certainty.

ECG readings generally worked as expected and one comparison produced results similar to a dedicated Kardia device. It remains a wellness feature rather than a substitute for clinical diagnostic equipment.

The Antioxidant Index attracts curiosity but little enthusiasm. It is repeatedly described as hard to act on or more of a gimmick than a genuinely useful health metric.

Samsung Health earns credit for allowing users to download their collected data, which supports data ownership. At the same time, AI-training settings may warrant an opt-out for users who are uncomfortable with that use of their data.

Several headline outdoor features arrived incomplete or unavailable, including parts of the diving experience and built-in trail discovery. Buyers interested in those specific capabilities should not assume every announced function is ready on day one.

Automatic pause and resume behavior works especially well during stops such as traffic lights, restarting quickly when movement resumes. This makes everyday activity tracking feel more hands-off and precise.

Haptics are a standout detail, with strong, precise feedback that can reliably signal calls and messages without sound. Several testers rank the vibration quality among the best they have used on a smartwatch.

Blood-pressure readings are a welcome addition and can be useful once configured, but setup requires cuff calibration and some phone restrictions still apply. Experiences range from readings that work fine to frustration with the setup burden.

Skin-temperature trends can feed Vitals and flag unusual overnight changes, giving the metric a practical role beyond simply showing a number. The usefulness comes mainly from baseline alerts rather than isolated temperature readings.

Daily calorie-burn estimates were considered surprisingly believable and close enough to other calculations to be useful. This is limited to one detailed assessment, but it was strongly positive.

Climb and descent guidance is useful for trail runners and cyclists because it surfaces gradient, elevation and upcoming hill information. The concept is strong, but separate elevation-accuracy concerns mean serious athletes may still want a dedicated sports watch.

Fitness Index, Heart Health Score and related scores make large amounts of health data easier to digest and give users concrete targets. The best implementations point toward what to improve rather than simply reporting past activity.

Native external-sensor support is a major sports limitation. Several testers strongly criticized the lack of straightforward chest-strap and broader sensor pairing inside Samsung’s workout environment, forcing workarounds or third-party apps.

Native running-power support is still missing, which is a notable omission for performance-focused runners. Dedicated sports watches remain better equipped for this metric.

Voice notes become much more useful when recordings sync to a Galaxy phone for AI summaries and generated notes. The integration turns a basic recorder into a practical capture tool.
