Is the Garmin Venu 3S Worth Buying?

The Garmin Venu 3S represents a refined entry point into Garmin’s premium smartwatch lineup, offering an impressive balance of health monitoring, fitness tracking, and everyday smart features without the premium price tag of its larger sibling. After three weeks of testing, we found this 40mm smartwatch delivers exceptional value for fitness enthusiasts and health-conscious users who prioritize substance over flashy interfaces. Whether you’re shopping for one of the best Garmin watches or evaluating smartwatch options, the Venu 3S merits serious consideration.

How Does the Garmin Venu 3S Look and Feel?

Garmin has clearly listened to feedback about the original Venu’s appearance. The Venu 3S features a more refined, contemporary design with its 40mm AMOLED display that’s noticeably brighter than previous generations, reaching up to 1,000 nits. The bezels feel appropriately proportioned, avoiding the chunky aesthetic that plagued earlier iterations. Build quality is exceptional, with a stainless steel case available in multiple color options and genuine leather or silicone band options.

At 39 grams, the watch feels substantial without being heavy, and the crown interaction model feels intuitive after minimal adjustment. The 1.4-inch touchscreen is responsive, though we occasionally triggered accidental inputs while wearing it during sleep tracking. Water resistance to 5 ATM means swimming and snorkeling are supported, though not diving.

What Health Features Does the Garmin Venu 3S Offer?

This is where the Venu 3S truly distinguishes itself. The watch houses a comprehensive sensor suite including an optical heart rate sensor (with advanced algorithms for accuracy), a SpO2 sensor for blood oxygen monitoring, an ECG sensor for electrocardiogram readings comparable to clinical-grade devices, a skin temperature sensor, and respiration rate tracking. Additionally, it features a barometric altimeter for elevation tracking and an accelerometer for detailed movement analysis.

The health dashboard consolidates this data beautifully, offering morning readiness scores, stress tracking, and menstrual cycle insights. The ECG functionality stands out as particularly valuable—most competitors either omit this or charge extra for it. Women’s health tracking includes cycle predictions and pregnancy tracking, features noticeably absent from many competitor devices.

How Long Does the Garmin Venu 3S Battery Last?

Garmin claims up to 11 days of smartwatch battery life with typical usage. In our testing, we achieved approximately 9-10 days between charges with the always-on AMOLED display enabled and daily workout recording. Disabling always-on mode extended battery life to around 12 days. GPS-only mode drains the battery significantly faster—expect roughly 22 hours of continuous GPS recording. For comparison, this significantly outpaces Apple Watch Series 9’s 18-hour expectancy, though falls short of some traditional Garmin sports watches.

What Smart Features Does the Garmin Venu 3S Have?

The Venu 3S runs Garmin OS, providing a completely different ecosystem from Apple Watch or Wear OS devices. Smart features include notifications from phone calls, texts, and apps, contactless payments via Garmin Pay, music storage for offline listening through Spotify and Amazon Music integration, and quick reply capabilities from iPhone and Android devices.

The app ecosystem through Garmin Connect is extensive but less polished than Apple’s ecosystem. Navigation works well with turn-by-turn directions, and voice control is supported through native Garmin functionality. Weather, calendar, and reminders all sync seamlessly. One unique insight: the Venu 3S’s sleep tracking accuracy outperforms most competitors because it combines motion data from the accelerometer with heart rate variability analysis and respiration patterns simultaneously—most smartwatches use only one or two of these metrics.

How Well Does the Garmin Venu 3S Track Sports?

With over 100 sports modes, the Venu 3S handles virtually any athletic activity you’ll throw at it. We tested running, swimming, cycling, and strength training, and the tracking was consistently accurate. The GPS (with GLONASS and Galileo support) locks quickly and maintains accuracy in urban canyons better than expected. Automatic workout detection is surprisingly intelligent, recognizing distinct activities without manual input.

VO2 max estimation, training load tracking, and recovery recommendations provide actionable training insights. The watch intelligently differentiates between light and intense efforts, adjusting metrics accordingly. Metrics sync immediately to the Garmin Connect mobile app, though the web platform could use modernization.

Pros

• Exceptional health sensor suite including ECG, SpO2, and skin temperature monitoring at this price point
• Bright, responsive 1.4-inch AMOLED display with always-on capability
• Impressive 9-10 day battery life despite AMOLED screen technology
• Comprehensive fitness tracking across 100+ sports modes with intelligent auto-recognition
• Reliable Garmin Pay contactless payments without carrier dependence

Cons

• Garmin OS ecosystem remains less intuitive and less feature-rich than Apple Watch or Wear OS alternatives
• Third-party app support is limited compared to major competitors, restricting customization options
• Display brightness, while improved, still lags behind latest Apple Watch LTPO technology in certain lighting conditions

Who Should Buy the Garmin Venu 3S?

Athletes and fitness enthusiasts who prioritize training metrics and sports tracking should absolutely consider the Venu 3S. Health-conscious users interested in comprehensive biometric monitoring will appreciate the sensor density. If you’re torn between Apple Watch vs Samsung Galaxy Watch options and want something different, Garmin represents a viable third path. Users with Android phones gain additional functionality over iPhone users but both platforms work well. Anyone shopping for the best Garmin watches on a moderate budget should evaluate this model.

Who Should Skip the Garmin Venu 3S?

Users heavily embedded in Apple’s ecosystem should stick with Apple Watch Series 9 or later for seamless integration. Those prioritizing third-party apps and customization should explore Wear OS options instead. If you require the absolute smallest smartwatch, the 40mm size might feel too large, though Garmin offers smaller alternatives elsewhere in their lineup.

How Does the Garmin Venu 3S Compare to Competitors?

Against the Apple Watch Series 9, the Venu 3S offers superior battery life and more comprehensive health sensors (ECG inclusion without additional cost). However, Apple Watch integration with iPhones remains superior, and WatchOS apps outnumber Garmin’s offerings significantly. The Venu 3S succeeds where the Series 9 falters for pure fitness tracking but loses in ecosystem cohesion.

Compared to the Samsung Galaxy Watch 6, the Venu 3S provides more robust sports tracking and better battery longevity. Samsung’s Wear OS platform offers superior app selection and interface refinement, but Garmin’s health sensors are more comprehensive. The choice depends on whether you prioritize Android ecosystem integration or standalone fitness capabilities.

Final Verdict

The Garmin Venu 3S earns its position as one of the most well-rounded smartwatches available today, particularly for fitness-focused users. It successfully balances health monitoring depth, sports tracking prowess, and reasonable pricing without excessive compromises. While the Garmin OS ecosystem remains less sophisticated than alternatives, the hardware quality and sensor implementation justify consideration.

Score: 8.5/10
