Garmin Venu 4 VS Huawei Watch Ultimate 2

Both watches share the same OLED/AMOLED display technology and an identical 22 mm band width, but their physical profiles diverge significantly. The Garmin Venu 4 is noticeably more compact at 45 × 45 mm and just 38 g, while the Huawei Watch Ultimate 2 measures 48.5 × 48.5 mm and weighs a substantial 80.5 g — more than double. That weight gap is the single most consequential design difference: over a full day or night of wear, the Venu 4 will feel nearly invisible on the wrist, whereas the Watch Ultimate 2's heft is likely to be noticeable, especially during sleep tracking or prolonged workouts.

On display sharpness, the Venu 4 holds a clear advantage with 458 ppi versus the Watch Ultimate 2's 311 ppi, despite the Huawei having a marginally larger 1.5″ screen. In practice, text, icons, and watch faces will appear crisper on the Venu 4. The Watch Ultimate 2 counters with sapphire glass — one of the hardest materials used in consumer watches, offering superior scratch resistance — while the Venu 4 relies on a branded damage-resistant glass that, though protective, does not reach sapphire's durability tier. Water resistance also strongly favors the Huawei, rated at 10 ATM / 150 m depth versus the Garmin's 5 ATM / 50 m, making the Watch Ultimate 2 genuinely suited for diving and serious aquatic use.

In summary, these two watches target different priorities. The Venu 4 wins on everyday wearability — lighter, slimmer, sharper display — while the Watch Ultimate 2 is built for durability and rugged environments, with superior water resistance and scratch-proof sapphire glass. Users who prioritize comfort and visual clarity will lean toward the Venu 4; those who need a watch that can withstand more extreme conditions should favor the Watch Ultimate 2.

The sensor suites on these two watches are remarkably similar — both pack the core health and navigation hardware that serious users expect: heart rate monitor, SpO2 (blood oxygen), GPS, accelerometer, gyroscope, barometer, compass, and temperature sensor. For the vast majority of activities, from hiking to gym sessions to sleep tracking, either watch delivers a comprehensive data picture without meaningful gaps.

The only spec that separates them is the cadence sensor, which the Huawei Watch Ultimate 2 includes and the Garmin Venu 4 does not. A dedicated cadence sensor measures steps or pedal strokes per minute, which is particularly valuable for runners refining their stride efficiency or cyclists monitoring their pedaling rhythm — metrics that can directly influence performance and injury prevention. The Venu 4 can estimate cadence via its accelerometer in many activity modes, but a dedicated sensor is generally more accurate and reliable, especially in conditions where wrist movement is inconsistent.

Overall, the sensor comparison is close to a draw for general users, but the Huawei Watch Ultimate 2 holds a narrow edge for athletes — specifically runners and cyclists — who rely on cadence data as a core training metric.

When it comes to activity tracking breadth, these two watches are nearly identical. Both cover the full spectrum of everyday and athletic monitoring — sleep tracking with reports, step counting, pace, elevation, route tracking, automatic activity detection, multi-sport mode, swim stroke counting, and even calorie intake logging. For most users, neither watch leaves a meaningful gap in day-to-day fitness coverage.

The single differentiator in this category is diving support: the Huawei Watch Ultimate 2 is explicitly designed for it, while the Garmin Venu 4 is not. This is more than a checkbox — a watch designed for diving typically includes dedicated dive modes with depth tracking, dive time logging, and surface interval monitoring, functionality that goes well beyond the standard waterproofing that both watches share. For anyone who dives recreationally or professionally, this distinction is significant. Both watches are, however, equally designed for golf, rounding out what is otherwise a fully matched feature set.

For the overwhelming majority of users, activity tracking is a dead heat between these two. The Huawei Watch Ultimate 2 claims a clear, targeted edge only for divers — a niche but meaningful advantage that the Garmin Venu 4 simply does not address.

Connectivity fundamentals are well matched here. Both watches support Wi-Fi, NFC for contactless payments, Galileo satellite navigation, and are compatible with both iOS and Android — and neither includes a cellular module, meaning both require a paired phone for calls and data when away from Wi-Fi.

The one point of separation is ANT+, a low-power wireless protocol supported by the Garmin Venu 4 but absent on the Huawei Watch Ultimate 2. ANT+ is widely used in the fitness equipment ecosystem — heart rate chest straps, cycling power meters, bike speed and cadence sensors, and gym machines from major manufacturers all commonly communicate via ANT+. For athletes who already invest in or plan to use external fitness accessories, ANT+ compatibility on the Venu 4 is a genuine, practical advantage that expands what the watch can connect to beyond its built-in sensors.

For general users who rely solely on the watch's onboard sensors and a smartphone connection, the two are effectively tied. But for the fitness-focused buyer with an existing or planned ecosystem of external sensors, the Garmin Venu 4 holds a clear connectivity edge thanks to its ANT+ support.

Battery performance here tells a split story that depends entirely on how you use the watch. For everyday wear, the Garmin Venu 4 is the clear winner at 12 days of battery life compared to the Huawei Watch Ultimate 2's 4.5 days — nearly three times longer. In practical terms, that gap means the Venu 4 user charges roughly twice a month, while the Watch Ultimate 2 user is reaching for a cable every few days, a meaningful friction point for continuous health tracking and sleep monitoring.

The GPS endurance figures, however, flip the narrative dramatically. The Huawei Watch Ultimate 2 delivers a staggering 192 hours of GPS battery life versus the Venu 4's 19 hours — a tenfold difference. For ultra-endurance athletes, expedition hikers, or anyone undertaking multi-day outdoor events with continuous GPS logging, the Watch Ultimate 2's figure is in a different league entirely. The Venu 4's 19 hours is adequate for most single-day activities, but would fall short on anything requiring sustained multi-day GPS tracking without access to a charger. The Watch Ultimate 2 also adds wireless charging, offering more flexibility in how and where it is topped up, while the Venu 4 is limited to wired charging.

There is no single winner here — the right call depends on use case. The Garmin Venu 4 is the stronger choice for daily convenience and low-maintenance wear. The Huawei Watch Ultimate 2 is built for users who push into extended outdoor missions where GPS longevity outweighs everything else.

Across the features category, these two watches are strikingly well-matched. Both offer a comprehensive health monitoring stack — ECG, HRV tracking, VO2 max, resting heart rate, irregular heart rate warnings — alongside a full suite of smart features including call handling, notifications, voice commands, silent and vibrating alarms, and fast GPS acquisition. For the vast majority of users, neither watch leaves a noticeable functional gap in this category.

The differences, while few, are worth noting. Internal storage stands at 8 GB on the Garmin Venu 4 versus 32 GB on the Huawei Watch Ultimate 2 — a fourfold advantage for the Huawei. More storage headroom is meaningful for users who want to load music, maps, or other offline content directly onto the watch without managing space carefully. The Watch Ultimate 2 also adds a built-in camera remote control function, a convenience feature the Venu 4 lacks, useful for triggering a paired smartphone camera hands-free during activities or group photos.

The Huawei Watch Ultimate 2 takes a modest but clear edge in this group. The camera remote is a minor lifestyle perk, but the substantially larger internal storage is a practical advantage that compounds over time — especially for users who rely on the watch as a standalone media or navigation device. Both watches share identical warranty coverage at 1 year, leaving no differentiation there.

The app and software category produces a rare outcome in this comparison: a perfect tie. Across all 25 tracked specs, the Garmin Venu 4 and Huawei Watch Ultimate 2 are identical — every feature present on one is present on the other, and the single absent feature (barcode scanner) is missing from both.

What makes this shared feature set notable is its genuine depth. Both platforms cover fitness fundamentals like calorie tracking, activity reports, exercise diary, goal setting, and live tracking, but also extend into lifestyle and wellness territory — water intake, weight and BMI tracking, and a full women's health suite including period notifications, fertile window display, ovulation prediction, and cycle start date forecasting. Add in maps, route support, coaching, voice feedback, music playback, and widget personalization, and both apps deliver a genuinely comprehensive experience rather than a bare-bones companion.

For any user whose decision hinges on software features and app capability, this category offers no basis for choosing one watch over the other. Both are ad-free, free to use, and broadly capable — the differentiators in this comparison lie elsewhere.

Most of the miscellaneous specs here are shared: both watches include a battery level indicator, sunrise/sunset times, auto pause, smart scale compatibility, and support for external heart rate monitors. Neither offers an external memory slot or a 3.5 mm audio jack, so those omissions are a non-issue for direct comparison purposes.

The one meaningful differentiator is desktop OS compatibility. The Garmin Venu 4 is compatible with both Windows and Mac OS X, while the Huawei Watch Ultimate 2 is listed as compatible with neither. In practice, most smartwatch management happens through a smartphone app, so desktop compatibility is rarely a daily concern — but it can matter for users who prefer to sync, manage, or back up data from a computer, or who work in environments where a desktop is the primary device.

The Garmin Venu 4 holds a narrow edge in this category solely due to its broader desktop OS support. It is not a decisive factor for most buyers, but for users who value the option to interact with their watch data from a Windows or Mac machine, the Venu 4 is the only choice of the two that accommodates that workflow.
