Compare Samsung Galaxy Watch 8 vs Garmin Forerunner 955

Automatic workout detection was generally prompt and useful for CrossFit, walks, bike rides, and common exercises, though one reviewer noted detection can take a few minutes.

Reviewers found useful automatic or semi-automatic detection in specific contexts, including ski runs, strength movements, and swim rest/stroke detection, though the evidence centers on sport-specific recognition rather than broad passive workout detection.

Reviewers treated the antioxidant index as a novel but uneven health metric: one called it unique, while several questioned usefulness, verification, or anxiety risk.

The app ecosystem is a strength because Google Play and Wear OS provide major smartwatch apps alongside Samsung's own software layer.

The Garmin ecosystem is seen as deep and expandable through sensors, Connect IQ, and watch/app services, but one reviewer called the on-watch app store experience limited and another found Garmin Connect dated.

Bands are usually described as soft, comfortable, and easier to swap, but the new proprietary lug system and compatibility limits reduce enthusiasm.

The strap setup is generally comfortable and durable, with reviewers noting snug flexible fit, soft silicone, metal buckles, and standard 22mm compatibility, but one reviewer said the band and case can trap water.

Battery life is the most consistent weakness: reviewers usually got about one day to a day and a half, with heavier use requiring daily charging.

Battery life is one of the strongest points: reviewers repeatedly reported roughly two weeks or more in smartwatch use, strong GPS runtimes, and only context-specific drains from multi-band GPS, music, notifications, and heavy use.

Blood oxygen tracking is repeatedly listed as available for sleep and general health monitoring, with reviewers treating SpO2 as a standard included health metric.

Blood oxygen tracking is well represented through Pulse Ox, sleep/altitude use cases, Health Snapshot, and sensor descriptions, but reviewers also note battery drain and that readings require proper conditions.

Bluetooth support is present for models, headphones, speakers, and phone-call features, with later reviews also noting Bluetooth 5.3.

Bluetooth support is strong for headphones and sensors, with reviewers citing Bluetooth headphones and broad ANT+/Bluetooth Smart sensor compatibility.

Brightness is a major upgrade, with multiple reviewers citing the 3,000-nit peak brightness as a useful step up.

Brightness is acceptable rather than class-leading; one review says the display is crisp and readable in sun but not the brightest.

Build quality is mostly positive thanks to sapphire glass, durability ratings, and the cushion case, although raised-screen confidence varies by reviewer.

Build quality is consistently praised as light but solid, with a tough resin or fiber-reinforced polymer case and durable glass, though it is not positioned as a luxury metal watch.

Button controls are useful but mixed: customizable presses and gestures help, while several reviewers prefer the Classic's tactile controls or find base buttons underused.

Reviewers strongly like the five-button control scheme, especially because it works with gloves, wet hands, workouts, and users who prefer not to depend on the touchscreen.

Call handling is well supported, with reviewers noting calls and texts from the watch and direct Bluetooth phone-call support.

Call handling is limited: reviewers note no hands-free calling, no Bluetooth calling, no microphone/speaker experience, and only basic alerts or call-related notifications.

Calorie usefulness is present but not a standout: reviewers mention Energy Score, calories burned, and manual food/calorie entry rather than deep calorie guidance.

One review found calorie estimates aligned well with phone/GPS app data, but calorie-specific evidence is limited compared with GPS, heart rate, and training metrics.

Charging convenience is mixed: the magnetic puck or cable is included, but there is no wall brick and reverse wireless charging is not supported.

Charging convenience is helped by long battery life and quick top-offs, though the watch still uses Garmin’s proprietary charging cable.

Charging speed ranges from solid short top-ups to underwhelming full charges, with reviewers reporting roughly 30 minutes to around half and up to nearly two hours for full.

Charging speed is praised, with reviewers reporting very quick top-offs such as full charging in about 30 minutes or meaningful charge recovery in minutes.

Coaching features are a major theme, especially Running Coach and sleep guidance; reviewers found them motivating and actionable but not always deeply personalized.

Coaching features are a strength: reviews cite Garmin Coach, training plans, daily suggested workouts, race tools, training feedback, and readiness-guided workout suggestions.

Comfort earns the strongest praise, with many reviewers saying the thinner design, fit, and band make it easy to wear all day, during workouts, and overnight.

Comfort is broadly positive, with reviewers repeatedly describing the watch as light, comfortable, unobtrusive, and suitable for long runs and daily wear.

The companion app experience is split: Samsung Health is praised as useful and well designed, but needing multiple apps and setup attention is a recurring friction point.

The companion app is useful and data-rich, with clear graphs and easier configuration, but reviews also call Garmin Connect dated, complicated, or easier to digest than the watch rather than effortless.

Contactless payments are clearly supported through NFC, Samsung Pay, Google Pay, or mobile payments, and reviewers treat them as expected smartwatch functionality.

Contactless payment support is useful through Garmin Pay and regional payment options, but bank/payment availability varies and support is not universally strong.

Cross-platform compatibility is a weakness because the watch targets Android/Samsung users and explicitly does not work with iPhone, with some features reserved for Samsung phones.

Cross-platform compatibility is positive where reviewed, with Garmin Connect available for iOS and Android and data syncing across Garmin’s platform.

Customization is strong through customizable tiles, stacked widgets, app layout options, and easy access to running tasks through the Now Bar.
