Quick Verdict
Too close to call on score alone: 0.3 points separate them. Ten days, an FDA-cleared ECG and full iPhone/Android parity — with a $6.99/mo AI paywall. The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) answers with a different set of strengths, so let the categories below decide it.
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) and Garmin Venu 4 (41mm) are both closely matched smartwatch models, and the Garmin Venu 4 (41mm) is $150 cheaper than the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) ($549.99 vs $699.99). On Ecosystem Freedom, the Garmin Venu 4 (41mm) leads (8.5 vs 2.5/10) — the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing. On App Ecosystem, the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads (8.5 vs 6.0/10) — whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. On Battery Life, the Garmin Venu 4 (41mm) leads (9.0 vs 7.8/10) — real endurance between charges, judged against what the claim actually assumes rather than the headline number. Overall, the Garmin Venu 4 (41mm) scores 8.1/10 across our 8 scoring categories versus 7.8/10 for the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium), though the gap is close enough that your specific use case should decide it. Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) | Garmin Venu 4 (41mm) |
|---|---|---|
| Price | $699.99 | $549.99 |
| Release Year | 2026 | 2025 |
| Phone Compatibility | Android only. Requires Android 13 or later with 1.5 GB RAM minimum. No iPhone support. On non-Samsung Android you lose ECG, blood pressure, SmartThings camera feeds, Camera Controller and DND/bedtime sync — the same list as the Galaxy Watch9. | Both iOS and Android, with no feature gated to a Garmin-branded phone (Garmin makes none). Garmin Connect is the same app on both platforms — the widest genuine compatibility of any premium watch here. |
| Claimed Battery Life (hrs) | 60 | 240✓ |
| What the Battery Claim Assumes | Samsung's 60-hour figure is quoted with the always-on display ON, which is unusually honest for this category — but it is still a mixed-use claim, not a workout claim. Continuous dual-band GPS and LTE-only use (with the phone left behind) drain it far faster. | Garmin's 10-day 41mm figure is smartwatch mode with the always-on display OFF (the 45mm is rated 12 days). Enabling the always-on display, multi-band GNSS or continuous pulse-ox roughly halves it; Garmin publishes a separate 'battery life assumptions' support page per size because the modes differ so much. |
| Case Size (mm) | 47 | 41 |
| Display | 1.52-inch Super AMOLED under sapphire crystal, up to 5000 nits — the brightest smartwatch display sold | 1.2-inch AMOLED with an optional always-on mode. Peak brightness is not published by Garmin. |
| Operating System | Wear OS (One UI Watch) | Garmin proprietary OS |
| Third-Party Apps | Google Play Store on the watch, same Wear OS catalogue as the Galaxy Watch9 | Garmin Connect IQ store — a real third-party store with watch faces, data fields and apps, but a much smaller and more fitness-skewed catalogue than the Play Store or App Store |
| Health Features Enabled in the US | ECG, irregular rhythm notifications and sleep apnea detection are FDA-cleared. Blood pressure rolled out in the US from 31 March 2026 but is not FDA-cleared, is Samsung-phone gated, and needs 28-day cuff re-calibration. BIA body composition included. | ECG app with AFib detection is FDA-cleared and available in the US (adults 22+ only, and region-restricted elsewhere). Also Pulse Ox, wrist temperature, HRV status, respiration and the new Health Status baseline alerts. No blood pressure and no hypertension notification. |
| Subscription Wall | No subscription for core metrics; bundled third-party fitness trials auto-renew at full price. | Core metrics are free, but Garmin now runs a paywall: Garmin Connect+ costs $6.99/mo and gates Active Intelligence AI insights, extra coaching and premium performance dashboards. Buying a $549.99 watch does not include it. |
| LTE Option | Not an option — LTE is built into every Ultra2 and included in the $699.99 price. You still pay a carrier for the line. | The Venu 4 has no LTE variant; Garmin's cellular models sit in other product lines. |
| Water & Dust Rating | 10 ATM (100 m), IP69K, MIL-STD-810H, EN13319 dive certified to 40 m | 5 ATM (50 m) |
| Battery Replacement | No consumer battery-replacement programme; the titanium case is sealed. | Garmin does not sell a user or dealer battery-replacement service for the Venu line; out-of-warranty support is a discounted replacement unit. |
| Warranty | 24 months | 12 months |
| Colors | Titanium Gray, Titanium Silver | Slate with Black band, Silver with Periwinkle band, Lunar Gold with Bone band |
Category Scores
Battery Life
The Garmin Venu 4 (41mm) leads clearly here, 9.0 against 7.8 — a 1.2-point margin on real endurance between charges, judged against what the claim actually assumes rather than the headline number. If that is what you are buying for, the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) does not close the gap elsewhere.
Health Tracking
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 8.8 against 8.2 — a 0.6-point margin on depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Fitness & GPS
The Garmin Venu 4 (41mm) is marginally ahead, 9.2 to 9.0. A gap this small rarely decides a purchase on its own, though it counts if workout tracking, GPS accuracy, sport modes and training analysis is your priority.
Ecosystem Freedom
The Garmin Venu 4 (41mm) leads clearly here, 8.5 against 2.5 — a 6.0-point margin on the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing. If that is what you are buying for, the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) does not close the gap elsewhere.
App Ecosystem
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 8.5 against 6.0 — a 2.5-point margin on whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Display
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 9.6 against 8.4 — a 1.2-point margin on panel type, brightness, always-on behaviour and legibility in sunlight. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Build & Durability
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 9.4 against 8.4 — a 1.0-point margin on case and glass materials, water and dust ratings, and how well it survives daily wear. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Value
The Garmin Venu 4 (41mm) is marginally ahead, 7.0 to 6.6. A gap this small rarely decides a purchase on its own, though it counts if what you get for the money once LTE upcharges and subscriptions are counted in is your priority.
