Garmin Vivoactive 6 vs Samsung Galaxy Watch 6

Garmin Vivoactive 6

A 1.2-inch AMOLED touchscreen under Corning Gorilla Glass 3 — bright, vibrant and a touch brighter than the Vivoactive 5. There's an optional always-on mode, at a real battery cost.

• 1.2-inch AMOLED touchscreen — bright, punchy and contrast-rich, and DC Rainmaker found it noticeably brighter than the Vivoactive 5.
• Readable outdoors with little glare; in dark conditions you rely on the backlight.
• Protected by Corning Gorilla Glass 3 rather than the sapphire of pricier Garmins.
• An optional always-on display is supported — but enabling it cuts battery life roughly in half.

Samsung Galaxy Watch 6

Super AMOLED with Sapphire Crystal, ~2,000 nits peak brightness. Larger usable display thanks to the thinner bezels. Always-on display supported.

• Larger usable display — the thinner bezels grew the screen while keeping the case compact.
• Super AMOLED with ~2,000 nits peak brightness — bright and readable outdoors.
• Sapphire Crystal protection — premium scratch-resistant glass.
• Always-on display supported — though Wired noted an earlier Galaxy Watch's display 'stubbornly resisting' wake gestures; the Watch 6's raise-to-wake is improved.
• Vibrant, sharp panel — Digital Trends calls Samsung's Galaxy Watch displays 'gorgeous.'

Garmin Vivoactive 6

Garmin's daily-wellness toolkit — Body Battery, HRV Status, Sleep Coach, stress, Pulse Ox — all driven by the older Elevate Gen 4 heart-rate sensor. There's no ECG. Heart-rate accuracy is okay rather than excellent, and sleep-stage detail is mixed.

• Garmin's full daily-wellness suite — Body Battery, HRV Status, stress, Pulse Ox and a 2-minute Health Snapshot reading.
• It keeps the older Elevate Gen 4 sensor — so there's no ECG, unlike Garmin's newer Venue watches.
• Heart-rate accuracy is okay — TechRadar measured it within roughly 13 bpm of a Polar H10 chest strap and called it 'fine.'
• The Quantified Scientist rates it among the weaker Garmin heart-rate sensors he has tested — a chest strap is recommended for hard workouts.
• Sleep-stage tracking is mixed — The Quantified Scientist measured ~73% deep-sleep agreement against a reference device, but REM detection is the clear weak point.
• A new Smart Wake alarm gently vibrates within a 30-minute window at a lighter sleep stage — though some testers found it imprecise.

Samsung Galaxy Watch 6

BioActive sensor — optical HR, ECG, BIA body composition, skin temperature. Sleep tracking with coaching. Comprehensive wellness suite, though HRV accuracy drew a caveat.

• BioActive sensor — optical HR, ECG, BIA body composition, and skin temperature in one sensor array.
• Expanded wellness features — Engadget: 'Samsung focused its efforts on expanding its wellness-centric features.'
• Sleep tracking with sleep coaching — detailed sleep stages plus a multi-week coaching program.
• DC Rainmaker found Samsung's HRV metrics 'far out of alignment' with other wearables on most nights — a sensor-accuracy caveat.
• BIA body composition — on-wrist body-fat and muscle-mass estimates, a Samsung-distinctive feature.

Garmin Vivoactive 6

80+ activity profiles, Garmin's training suggestions and recovery metrics, plus newly added Running Power and running dynamics. GPS is single-frequency but accurate enough for everyday training. Step counting is the soft spot.

• 80+ activity profiles with Garmin's training and recovery metrics — T3 calls it a 'criminally underrated' smartwatch.
• The Vivoactive 6 adds Running Power and running dynamics — once advanced-tier running features.
• GPS is single-frequency, not multi-band — German Accent Reviews found it accurate enough for 99.9% of users, just shy of the pricier Garmins' precision.
• GPS locks quickly — AbbyBReviewing found a fix within about 20 seconds, and a 1-hour run burned only 6-7%.
• Step counting undercounts — Ultra Value Tech measured roughly 15-20% fewer steps than a Galaxy Watch worn alongside.
• 5 ATM water resistance covers pool and open-water swimming.

Samsung Galaxy Watch 6

100+ workout modes, personalized HR zones, custom workouts, auto-detection. Samsung Health analytics. Solid for everyday fitness; serious athletes still lean Garmin.

• 100+ workout modes — broad activity coverage through Samsung Health.
• Personalized heart-rate zones + custom workouts — tailored training guidance.
• Automatic workout detection — catches walks, runs, and cycling without manual start.
• GPS with GLONASS, Galileo, BeiDou — multi-constellation tracking for outdoor activities.
• 5 ATM water resistance — pool + open-water swim tracking supported.

Garmin Vivoactive 6

Garmin rates the Vivoactive 6 at up to 11 days in smartwatch mode — far beyond an Apple Watch. Real-world results land at roughly 7-9 days with the always-on display off, dropping to 3-4 days with it on. A full charge takes around 1 hour 45 minutes; there's no wireless charging.

• Rated up to 11 days in smartwatch mode and around 5 days with the always-on display enabled.
• Real-world testing landed around 7-9 days with the always-on display off — German Accent Reviews and AbbyBReviewing both reported similar figures.
• With the always-on display enabled, real-world life drops to roughly 3-4 days.
• TechRadar got about 8.5 days with three GPS workouts plus a gym session and near-constant wear.
• GPS runtime is around 21 hours; a full charge takes roughly 1 hour 45 minutes via USB-C, and there's no wireless charging.

Samsung Galaxy Watch 6

300mAh (40mm) / 425mAh (44mm). ~30 hours typical use, slightly improved over the Watch 5. Wireless fast charging. Daily-ish charging required.

• ~30 hours typical use — Engadget notes Samsung 'extended battery life' over the Watch 5, though daily-ish charging remains.
• 425mAh battery (44mm) / 300mAh (40mm) — the larger model lasts noticeably longer.
• Wireless fast charging — Notebookcheck confirms 'wireless charging, fast charging / Quickcharge.'
• Battery still trails Garmin by a wide margin — ~30 hours vs Garmin's multi-week endurance.
• AOD on cuts battery noticeably — AOD off is the way to comfortably reach the full-day rating.

Garmin Vivoactive 6

Garmin OS with a refreshed grid-style UI, Garmin Connect, Connect IQ and Garmin Pay. 8GB of storage — double the Vivoactive 5 — supports offline music. It works with iOS and Android. The software is functional but reviewers find it clunky, and Garmin keeps adding features via free updates.

• 8GB of storage — double the Vivoactive 5 — supports offline music storage.
• A refreshed grid-style control layout and customizable back button streamline everyday navigation.
• The software is more fully featured than before, but Trusted Reviews still calls it 'a bit of a pig to navigate, clunky and quite slow.'
• Garmin keeps adding features for free — it extended the Venu 4's Health Status feature to the Vivoactive 6 via a software update.
• Garmin Pay handles contactless payments, and the watch works with both iPhone and Android.

Samsung Galaxy Watch 6

Wear OS 4 + One UI 5 Watch. Samsung Health, Samsung Pay + Google Wallet, Google Play Store. Best inside the Samsung phone ecosystem. Android-only.

• Wear OS 4 + One UI 5 Watch — a complete, polished Wear OS experience with the full Google Play Store.
• Samsung Health — the analytics backbone; some features (BIA, ECG) are tied to a Samsung phone.
• Samsung Pay + Google Wallet — both contactless payment options supported.
• Best inside the Samsung ecosystem — works with any Android phone, but BIA + ECG need a Samsung phone.
• Android-only — no iOS compatibility.

Garmin Vivoactive 6

A 5 ATM (50m) water resistance rating covers swimming, and the Gorilla Glass 3 lens resists everyday scratches. The polymer case with aluminum bezel is sturdy for daily wear, though it's not a rugged adventure watch.

• 5 ATM (50m) water resistance — rated for pool and open-water swimming, and fine in the shower.
• Corning Gorilla Glass 3 resists everyday scratches — owners report it holding up well to knocks and corners.
• The fiber-reinforced polymer case with aluminum bezel is sturdy for daily wear — but this is a lifestyle watch, not a MIL-STD adventure tool.
• Unlike Garmin's newest rugged watches, the buttons are not leak-proofed — avoid pressing them underwater.

Samsung Galaxy Watch 6

5 ATM (50m) water resistance + IP68 + MIL-STD-810H. Sapphire Crystal display + aluminum case. Ruggedized for everyday wear.

• 5 ATM + IP68 + MIL-STD-810H — Notebookcheck confirms the full Galaxy Watch durability ratings.
• Sapphire Crystal display protection — premium scratch resistance.
• Aluminum case — durable and lightweight for everyday wear (the Classic uses stainless steel).
• Ruggedized + waterproof — built to take everyday and workout abuse.

Garmin Vivoactive 6

Single-frequency GPS across multiple satellite systems, Garmin Pay via NFC, Bluetooth and ANT+. There's no LTE, no on-watch maps, and no speaker or microphone for calls.

• Single-frequency GPS across multiple GNSS systems — the Vivoactive 6 adds QZSS and BeiDou over the Vivoactive 5.
• Bluetooth and ANT+ — pair chest straps and broadcast heart rate to apps like Zwift.
• No LTE and no speaker or microphone — there's no on-watch calling, unlike Garmin's Venue line.
• No downloadable maps — the Vivoactive line has never had on-watch mapping.

Samsung Galaxy Watch 6

Multi-constellation GPS (GPS, GLONASS, Galileo, BeiDou), optional LTE, NFC for Samsung Pay + Google Wallet, Bluetooth, Wi-Fi.

• Multi-constellation GPS — GPS, GLONASS, Galileo, BeiDou for accurate outdoor tracking.
• Optional LTE — standalone calls, texts, and music streaming without the phone.
• NFC for Samsung Pay + Google Wallet — both contactless options.
• Bluetooth + Wi-Fi — full Wear OS connectivity stack.
• Single-band GPS — accurate for everyday use, but not the multi-band precision of higher-tier sports watches.

Garmin Vivoactive 6

At $299.99 the Vivoactive 6 is one of the best-value ways into Garmin's ecosystem, undercutting the Apple Watch and Galaxy Watch on price and battery. The catch is internal: it's so close to the Vivoactive 5 that a discounted 5 is the smarter buy for many.

• $299.99 launch price — Lexy Savvides notes it offers better battery and more sports features than the Apple Watch SE and Galaxy Watch at the price.
• T3 calls it a 'criminally underrated' Garmin smartwatch — strong value for an 80+ sport-mode watch.
• vs the Vivoactive 5: reviewers agree the hardware is nearly identical, so a discounted Vivoactive 5 is the better value for buyers who don't need the newer UI.
• vs the Apple Watch SE / Galaxy Watch: the Vivoactive 6 wins decisively on battery and Garmin's deeper fitness data; the others win on apps and smartwatch polish.
• Best for: anyone who wants Garmin's wellness ecosystem and multi-day battery for $300 and isn't a serious runner chasing precise data.

Samsung Galaxy Watch 6

$299 (40mm) / $329 (44mm) launch. Now superseded by the Galaxy Watch 7 + 8 — a strong value if discounted. Competes with the Pixel Watch and (for iOS) the Apple Watch.

• $299 (40mm) / $329 (44mm) launch — Engadget calls it 'a fair price point' for a flagship Wear OS watch.
• Now superseded by the Galaxy Watch 7 + 8 — Digital Trends notes the Watch 7's 'display and specs are similar.' The Watch 6 is a strong value if discounted.
• vs Galaxy Watch 6 Classic: the Classic adds the physical rotating bezel + stainless steel for more money.
• vs Pixel Watch 2: both run Wear OS; Samsung offers more sizes + BIA body composition, Pixel offers tighter Fitbit integration.
• Best for: Samsung phone owners who want a complete Wear OS smartwatch with a great display and full health suite — and find the Watch 6 discounted now that newer models exist.
