Garmin Fenix 8 Solar vs Samsung Galaxy Watch 8

Garmin Fenix 8 Solar

MIP (memory-in-pixel) transflective display with Power Glass solar charging. Exceptionally sunlight-readable and power-efficient — but not vivid or colorful like AMOLED.

• MIP transflective display — Notebookcheck: 'a more power-efficient technology that thrives in direct sunlight,' the Solar model's defining choice.
• Power Glass solar charging — the display lens harvests sunlight to extend battery, the Solar model's headline feature.
• Not as vivid as AMOLED — Wired notes MIP is 'not as stunning as an AMOLED screen'; this is the deliberate trade-off.
• Always-on by nature — MIP displays are always on with no battery penalty, ideal for glanceable data.
• Touchscreen + five-button control — the touchscreen complements physical buttons for map panning and menus.

Samsung Galaxy Watch 8

A Super AMOLED panel — 1.34-inch on the 40mm, 1.5-inch on the 44mm — that now peaks at a brilliant 3,000 nits, a big jump over the Galaxy Watch 7's 2,000. Sapphire crystal protects it, and there's an always-on mode.

• Peak brightness jumps to 3,000 nits — a major upgrade over the Galaxy Watch 7's 2,000 nits, easily readable in direct sun.
• Crisp, colorful and fluid Super AMOLED — TechMishka says it 'looks amazing in all conditions.'
• Sapphire crystal protection on every size — premium scratch resistance.
• The display stays round despite the squircle case — TechMishka notes the round panel still limits how much information fits on screen.

Garmin Fenix 8 Solar

Elevate Gen 5 optical HR with skin temperature, SpO2, HRV Status, Body Battery, sleep tracking, Morning Report. ECG support. Garmin's latest sensor generation.

• Elevate Gen 5 optical HR sensor — Garmin's latest HR generation with built-in skin-temperature sensing.
• ECG support — heart-rhythm checks on the wrist (region-dependent).
• HRV Status + Body Battery + sleep tracking + Morning Report — Garmin's full wellness + recovery analytics.
• SpO2 (pulse ox) — on-demand and continuous; useful for altitude acclimatization on mountain adventures.
• Optical HR is reliable for steady-state; like all wrist optical HR, less accurate than a chest strap for intervals.

Samsung Galaxy Watch 8

This is the Galaxy Watch 8's strongest card — the deepest health suite of any Wear OS watch: ECG, blood pressure, body composition, SpO2, skin temperature, plus new metrics like the Antioxidant Index, Vascular Load and AGEs Index. Heart-rate accuracy during exercise is the weak spot.

• The deepest Wear OS health suite — ECG, blood pressure monitoring, body composition (BIA), SpO2 and skin temperature all on board.
• New wellness metrics — an Antioxidant Index, Vascular Load and an AGEs (cellular aging) score turn raw data into longer-term health guidance.
• Sleep tracking is a standout — Android Authority calls the Galaxy Watch 8 its favorite smartwatch for sleep tracking.
• Heart-rate accuracy lags rivals — The Quantified Scientist found it often read too low and lagged behind real heart-rate changes during exercise.
• The optical heart-rate hardware is essentially unchanged from the Galaxy Watch 7 — a disappointment for accuracy-focused buyers.

Garmin Fenix 8 Solar

Garmin's deepest training-science suite — Training Readiness, Endurance Score, Hill Score, Acute/Chronic Load, full multisport + triathlon modes. The serious-athlete benchmark.

• Garmin's deepest training-science suite — Training Readiness, Endurance Score, Hill Score, Acute/Chronic Load.
• Full multisport + triathlon modes — Digital Trends: 'a versatile multisport GPS smartwatch for outdoor enthusiasts.'
• The MIP display + solar make the Fenix 8 Solar the natural pick for multi-day expeditions where recharging isn't possible.
• Advanced running metrics — running power, ground contact time, vertical oscillation, all without external sensors.
• Daily suggested workouts + race predictor + PacePro — Garmin's coaching engine, among the deepest in any smartwatch.

Samsung Galaxy Watch 8

Samsung Health workout tracking with dual-frequency GPS, automatic exercise detection and a new adaptive Running Coach. GPS distance is the best of any Samsung watch yet, though still behind a dedicated sports watch — and GPS workouts drain the battery hard.

• A new adaptive Running Coach delivers real-time pacing and audio feedback during runs.
• Dual-frequency GPS — distance accuracy is the best Samsung has managed yet, measured around 5.8% off outdoors, though still behind an Apple Watch.
• GPS locks fast — Ultra Value Tech got a fix in about 3 seconds in an urban area.
• GPS workouts drain the battery hard — a 1-hour run can eat 15-20%, capping GPS endurance.
• Automatic workout detection works, though it can be slow to recognize a session has started.

Garmin Fenix 8 Solar

Up to ~48 days in always-on smartwatch mode with solar — the longest battery of any Fenix 8. Solar charging extends runtime further in sunlight. Proprietary USB-C charging.

• Up to ~48 days in always-on smartwatch mode with solar — Notebookcheck cites the 48-day figure; the longest of any Fenix 8.
• Solar charging — Power Glass harvests sunlight to extend battery, most effective for sun-exposed outdoor athletes.
• Outlasts the Fenix 8 AMOLED — the MIP display + solar combination is the endurance-maximized choice.
• Multi-band GPS battery measured in days — supports ultra-endurance and multi-day expedition tracking.
• Proprietary Garmin USB-C charging cable — solar supplements but doesn't replace cable charging.

Samsung Galaxy Watch 8

The Galaxy Watch 8's clearest weakness. Samsung rates it at 40 hours (always-on display off) or 30 hours (on), and real-world results are merely okay — roughly 27-45 hours depending on settings, with the 44mm a particular underperformer. A full charge takes around an hour to 90 minutes.

• Rated 40 hours with the always-on display off and 30 hours with it on — an 8% bigger battery than the Galaxy Watch 7.
• Tech Spurt got roughly 36 hours from a full charge — wishing it could clear 48 hours so it wouldn't need daily charging.
• Endurance testing exposed a 44mm quirk — The Product Reviewer measured the 44mm at just 27 hours and, oddly, the smaller 40mm lasting longer at 32 hours.
• Lighter use stretches it further — one tester pushed the 44mm Bluetooth model to about 45 hours with two nights of sleep tracking.
• A full charge takes roughly 1 hour to 1 hour 20 minutes via the 10W wireless puck — slower than rivals.

Garmin Fenix 8 Solar

Garmin OS + Garmin Connect + Connect IQ store. Built-in speaker + microphone (NEW for Fenix) for voice calls + voice assistant. Garmin Pay. Works with iOS + Android.

• Built-in speaker + microphone — NEW for the Fenix line; Digital Trends confirms 'a built-in speaker and microphone for calls and voice assistance.'
• Garmin OS + Connect IQ store — apps, watch faces, data fields; a mature ecosystem.
• Voice Commands — control workouts and watch functions hands-free, with ongoing feature updates.
• Garmin Connect app — praised for analytics depth, frequently criticized for UI polish.
• Works with both iOS and Android — cross-platform; Garmin Pay for contactless payments.

Samsung Galaxy Watch 8

One UI Watch 8 on Wear OS 6, running on the 3nm Exynos W1000 with 2GB of RAM and 64GB of storage. Gemini is built into the wrist. Performance is snappy and Samsung Health is comprehensive — but the deepest features need a Samsung phone, and there's no iOS support.

• One UI Watch 8 on Wear OS 6 — snappy and smooth on the 3nm Exynos W1000 chip.
• Gemini is built into the wrist — the Galaxy Watch 8 was among the first smartwatches to run Google's new AI assistant natively.
• 2GB of RAM and 64GB of storage — double the Galaxy Watch 7, with room for plenty of offline music.
• The deepest health features need a Samsung phone — full functionality is gated to Samsung handsets, and there's no iOS support at all.
• Samsung still locks down what users can tweak — TechMishka notes the UI is enjoyable but Samsung 'holds too much control.'

Garmin Fenix 8 Solar

Dive-rated water resistance + MIL-STD-810 testing. Fiber-reinforced polymer or titanium, Sapphire crystal options. Leak-proof buttons. Built for serious expedition and underwater use.

• Dive-rated water resistance — the leak-proof buttons enable underwater use, a Fenix 8 hardware milestone.

• Fiber-reinforced polymer or titanium, with Sapphire crystal options — premium, scratch-resistant adventure construction.
• The MIP display + solar build is especially suited to remote, off-grid expeditions where battery is critical.

Samsung Galaxy Watch 8

Sapphire-crystal glass over an armor-aluminum case, rated 5 ATM plus IP68 and MIL-STD-810H. It holds up well to everyday knocks — a month of heavy wear left long-term reviewers with barely a scratch.

• 5 ATM plus IP68 water and dust resistance — fine for swimming, showering and rain.
• Sapphire crystal holds up well — a month of heavy wear left long-term reviewers with barely a scratch on the glass.
• Armor aluminum case with MIL-STD-810H certification — durable for daily wear, though not a rugged adventure watch.

Garmin Fenix 8 Solar

Multi-band (dual-frequency) GPS, full-color TopoActive maps, NFC for Garmin Pay, Bluetooth, ANT+, Wi-Fi. No LTE (that's the Fenix 8 Pro's domain).

• Multi-band (dual-frequency) GPS — accurate tracking in urban canyons, dense forest, and deep valleys.
• Full-color TopoActive maps — on-watch turn-by-turn navigation, a core Fenix capability.
• ANT+ + Bluetooth — pair chest straps, footpods, power meters, and cycling sensors.
• NFC for Garmin Pay + Wi-Fi for sync.
• No LTE on the standard Fenix 8 Solar — satellite + LTE are reserved for the Fenix 8 Pro.

Samsung Galaxy Watch 8

Dual-frequency GPS, Bluetooth, Wi-Fi and NFC payments. An optional LTE model adds standalone connectivity for about $50 more.

• Dual-frequency GPS, Bluetooth, Wi-Fi and NFC — the full connectivity set.
• An optional LTE model adds standalone connectivity for roughly $50 more.
• NFC payments work, but Tech Spurt notes Samsung doesn't make it easy to swap the default Samsung Wallet for Google Wallet.

Garmin Fenix 8 Solar

$1,099-$1,199+ launch. The endurance-maximized adventure flagship. Competes with the Fenix 8 AMOLED, the Apple Watch Ultra, and the Coros Vertix. Ages well and holds value.

• $1,099-$1,199+ launch — a genuine four-figure watch, especially in Sapphire Solar trims.
• vs Fenix 8 AMOLED: longer battery + better sunlight readability vs a vivid, colorful screen. A genuine preference split.
• Wired's framing: the Fenix series is 'the best sports watch period' — the Solar is the endurance-focused variant.
• vs Apple Watch Ultra: Garmin wins on battery + training depth + dive computer + cross-platform support; Apple wins on smart features + LTE + ecosystem for iPhone owners.
• Best for: serious adventurers and expedition athletes who prioritize the longest possible battery and sunlight readability above screen vibrancy — and can justify the four-figure price.

Samsung Galaxy Watch 8

At about $349.99 (40mm) rising to roughly $429.99 for the 44mm LTE, the Galaxy Watch 8 took a price hike reviewers widely call unjustified. It's the richest-software Wear OS watch — but the Pixel Watch 4 and OnePlus Watch 3 both counter hard on, respectively, polish and battery.

• PhoneArena's verdict: a 'brand-new design that looks original and grows on you, but the price hike is unjustified.'
• It starts around $349.99 for the 40mm and climbs to roughly $429.99 for the 44mm LTE — about $50 more than the Galaxy Watch 7.
• vs the OnePlus Watch 3: reviewers repeatedly point to the OnePlus for 3-4 days of battery against the Galaxy Watch 8's day-and-a-half.
• It's an iterative update — Tavesper sums it up as 'minor changes' that don't make it significantly better than the Galaxy Watch 7.
• Best for: Samsung phone owners who want the deepest health software in a Wear OS watch and can live with daily charging.
