Stripped back but still solid

The Vivoactive 6 keeps things light and simple, offering core tracking features in a smaller, more affordable package. It skips the extras like multi-band GPS, ECG and advanced coaching, but still delivers solid performance for everyday use. It’s a practical choice if you don’t need the deeper metrics or premium materials of the Venu line.

Pros

• Affordable price for a watch with GPS, music and NFC
• Lightweight and comfortable
• AMOLED display with good resolution
• Solid battery life, even with always-on display
• Supports core sensors and fitness tracking features

Cons

• No multi-band GNSS
• No ECG, skin temperature and barometric altimeter
• No speaker, microphone or voice assistant support
• Lacks advanced training tools

The Garmin Vivoactive 6 slots in just below the Venu line, offering many of the same tracking features in a lighter and more affordable package. It keeps the round AMOLED display and core Garmin experience, but trims back on premium materials, sensors and extras to hit a lower price point.

The Venu 4, on the other hand, builds on what the Venu 3 started. It adds multi-band GPS, a stainless steel bezel, LED flashlight and deeper health insights. There’s also more in the way of training guidance, coaching and advanced running metrics.

That extra hardware and software comes with trade-offs. The Venu 4 is heavier, more expensive and slightly shorter on battery life in some modes. Vivoactive 6 may not have the same feature list, but for many users, it might be enough.

Here’s how they compare head to head.

Garmin Venu 4 vs Vivoactive 6: Tech specs comparison

Design is similar

Starting off with design, and both watches stick with Garmin’s round shape, two-button layout and AMOLED touchscreens. The Venu 4 gives you a choice of 45mm or 41mm case sizes. Vivoactive 6 only comes in one size at 42mm, which sits right between the two Venu options. That makes it a safe middle ground for most wrists, but you lose the flexibility of picking a smaller or larger case.

Materials also differ slightly. Venu 4 combines a stainless steel bezel with a fiber-reinforced polymer case. Vivoactive 6 uses the same case material, but swaps in anodized aluminum for the bezel instead. Both have Corning Gorilla Glass 3 protecting the display, so scratch resistance is similar. The Venu 4 just feels a bit more refined in the hand. And it looks slightly more premium.

Weight is where the difference is more obvious. The 45mm Venu 4 weighs 56 grams, while the 41mm version drops that to 46 grams. Vivoactive 6 is noticeably lighter at just 36 grams. That’s something you’ll feel during long runs or sleep tracking. Vivoactive is easier to wear around the clock, while the Venu 4 has more presence on the wrist.

Colour options also reflect the difference in approach. Venu 4 sticks to safer tones, with the 45mm available in Slate or Silver, and the 41mm in Lunar Gold, Silver or Slate. Vivoactive 6 gets more playful, with combinations like Jasper Green, Pink Dawn or Lunar Gold with a bone-coloured strap. If you want something low-key, Venu 4 fits the bill. If you prefer a bit more personality, Vivoactive 6 gives you that out of the box.

Essential reading: Top fitness trackers and health gadgets

An important addition with the Venu 4 is the built-in LED flashlight. It’s tucked into the top of the watch. Vivoactive 6 leaves that out, so if you’re need a handy flashlight during evening walks or pre-dawn training, it’s something to consider.

Under the hood – where Venu 4 pulls ahead

Under the hood is where the Venu 4 really starts to pull ahead. It packs in a broader sensor set and more advanced positioning tech than the Vivoactive 6.

Now make no mistake – both watches include the usual core sensors. This includes an accelerometer, compass, gyroscope, thermometer, ambient light sensor, optical heart rate and Pulse Ox. But Venu 4 upgrades the heart rate to Elevate V5. Vivoactive 6 uses the older Elevate V4.

The Venu 4 also adds a few extras you won’t find on Vivoactive 6. That includes ECG, skin temperature and a barometric altimeter. Those features open the door to things like on-demand heart rhythm checks, heat response tracking and elevation data during hikes or hill runs. Vivoactive 6 doesn’t offer any of those.

GNSS is another area where the two watches differ. Both support GPS, GLONASS, Galileo, QZSS and Beidou. But only the Venu 4 offers multi-band support. That means it can lock onto multiple frequency bands from satellites, which helps improve location accuracy.

Elsewhere, both watches have Wi-Fi, Bluetooth and ANT+. You get offline music and Garmin Pay on both too. But only the Venu 4 includes a built-in speaker and microphone. That gives it voice assistant support, phone call capability (when connected) and audio prompts during workouts. Vivoactive 6 skips all that.

Battery life – how far each goes?

Battery life is one area where the Venu 4 and Vivoactive 6 trade blows depending on how you use the watch. In basic smartwatch mode, the 45mm Venu 4 gets up to 12 days, just edging out the 11 days offered by Vivoactive 6. But Vivoactive holds up better with always-on display turned on, managing 5 days compared to 4 on the larger Venu 4. Battery saver mode stretches both watches into multi-week territory, though Venu 4 still leads with a claimed 25 days.

For GPS tracking, the numbers flip. Vivoactive 6 pulls ahead in GPS-only mode with 21 hours, beating the 20 hours on Venu 4. In all-systems GNSS mode, it lasts 17 hours versus 19 on the Venu 4, though the gap narrows further when music is involved. The real distinction is multi-band support. Venu 4 offers that option, delivering up to 17 hours without music or 9 with it. Vivoactive 6 skips multi-band entirely, so if you want the best accuracy in dense cities or rough terrain, that feature could tip the scales.

The 41mm Venu 4 follows the same pattern, just scaled down slightly. You get 10 days in smartwatch mode, 3 with AOD, and up to 15 hours of GPS-only use. That’s still solid, but Vivoactive 6 remains competitive despite its lower price tag.

Smart features and daily tools

Venu 4 pulls ahead when it comes to smart functionality. It supports Bluetooth phone calls, voice assistant interaction and on-device voice commands. That makes it more useful in hands-free situations, whether you’re taking a call on the move or triggering a timer with your voice. Vivoactive 6 skips all of that. You’ll still get notifications and basic smart features, but nothing close to the same level of interaction.

You also get extras like Color Shift for nighttime readability, live event sharing and support for on-watch shortcuts. Venu 4 packs in more quality-of-life tools aimed at everyday convenience, not just fitness tracking.

Health and wellness tracking

Both watches cover core wellness tracking like heart rate, Pulse Ox, stress and respiration. But Venu 4 goes further. It adds skin temperature tracking, a health status overview widget and an automatic sleep alignment feature that helps adjust your circadian rhythm over time. There’s also Garmin’s Jet Lag Adviser, which builds on that same principle but applies it to travel across time zones.

Vivoactive 6 leaves all of those out. It still handles the basics well, but doesn’t offer as much long-term insight into how your body is adapting to stress, travel or recovery.

Workout suggestions and coaching

Venu 4 includes a broad set of daily suggested workouts. That covers running, walking, cycling and fitness-based sessions, many of which are heart rate-based. Walking even includes a duration-based option. On top of that, you get Garmin Fitness Coach and Cycling Coach support, both of which offer more structured planning.

There’s also support for mixed session multisport and traditional multisport workouts. Vivoactive 6 doesn’t include these coaching features or structured daily plans. It’s built more around tracking than guiding.

Training tools and analysis

This is where the difference becomes clearer. Venu 4 supports everything from training load focus and recovery time to race widgets and course guidance. You can track your VO2 Max on trail runs, monitor heat and altitude acclimation and get performance condition mid-run.

Even finer details are covered, like configurable lap alerts, virtual partner, finish time predictors and load ratio. The data feeds into Garmin’s unified training status system, which gives you a more complete view of readiness and recovery. Vivoactive 6 does include some elements like heart rate broadcasting and a limited version of recovery time, but the rest is missing.

Running metrics

Runners get far more with the Venu 4. It includes advanced metrics like vertical oscillation, ground contact time (with accessory), stride length, grade-adjusted pace and lactate threshold. There’s also support for Garmin’s running power and trail-specific features like auto climb and course-aware race predictions.

These metrics help fine-tune performance and pacing, especially for competitive runners. Vivoactive 6 doesn’t support any of these advanced metrics, so if running data is a priority, the Venu 4 is the obvious choice.

Outdoor and navigation features

If you spend time outdoors, Venu 4 brings more to the table. It offers point-to-point navigation, real-time breadcrumb trails, TracBack, elevation profiles and even a future elevation plot. There’s a barometric trend indicator with storm alerts, vertical speed data, and sun and moon tracking.

UltraTrac mode extends battery life for longer efforts, and features like Auto Rest and Up Ahead round out the outdoor profile. Vivoactive 6 isn’t built for navigation. It covers standard GPS tracking, but none of these additional tools.

Cycling extras

Cyclists also get more with Venu 4. There’s support for courses, power curves, FTP-based workouts and max power lap stats. It works with Garmin’s Vector and Rally power meters, as well as Varia headlight and camera accessories.

Both watches support speed and cadence sensors, but only Venu 4 rounds out the cycling experience with proper power data and external hardware support. Vivoactive 6 is more of a passive tracker in comparison.

Extra features on Venu 4 comparison table

Which one should you go for?

If you want the more complete watch, go with the Venu 4. It gives you better sensors, more accurate GPS, stronger coaching tools and proper training analysis. You also get extras like voice calls, race predictions, power data and navigation features that the Vivoactive 6 doesn’t offer at all.

But it comes at a cost. Venu 4 is heavier, more expensive and slightly shorter on battery in most modes. If you don’t need ECG, skin temperature, multi-band GNSS or deep training metrics, the Vivoactive 6 covers the basics well. You still get Garmin’s core tracking, AMOLED screen, and a watch that’s light enough to wear around the clock.

For casual users, the Vivoactive 6 is probably enough. For runners, outdoor users or anyone who wants more structure and depth, the Venu 4 is the better fit.
