Smartwatches / Garmin
Garmin Venu 4 (41mm)
Ten days, an FDA-cleared ECG and full iPhone/Android parity — with a $6.99/mo AI paywall.
Overall score 8.1/10
Pros
- + Ten days of battery with an AMOLED screen, versus one day from Apple and Samsung
- + FDA-cleared ECG that works identically on iPhone and Android
- + Connect IQ is a real third-party store, unlike Fitbit OS, Zepp OS or Withings
- + Best-in-class training analysis, sleep metrics and Health Status baseline alerts
Cons
- − $549.99 and Garmin still charges $6.99/mo for Connect+ to unlock Active Intelligence and premium coaching
- − The 10-day claim is with the always-on display off; turn it on and you lose roughly half
- − Connect IQ apps are fitness-skewed — it is not a substitute for a Play Store
- − No LTE, no blood pressure, no hypertension notifications
- − No battery replacement service; out of warranty means buying a discounted replacement
Garmin Venu 4 (41mm) review: what the specs say
Ten days, an FDA-cleared ECG and full iPhone/Android parity — with a $6.99/mo AI paywall. At $549.99, Garmin's 2025 model sits at the premium end of the category — the smartwatches we compare run from $79.99 to $799. It scores 8.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Fitness & GPS at 9.2/10 — workout tracking, GPS accuracy, sport modes and training analysis. The weakest is App Ecosystem at 6.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: $549.99 and Garmin still charges $6.99/mo for Connect+ to unlock Active Intelligence and premium coaching; and the 10-day claim is with the always-on display off; turn it on and you lose roughly half. Every specification on this page comes from Garmin's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Phone Compatibility | 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 | 240 hrs |
| What the Battery Claim Assumes | 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 | 41 mm |
| Display | 1.2-inch AMOLED with an optional always-on mode. Peak brightness is not published by Garmin. |
| Operating System | Garmin proprietary OS |
| Third-Party Apps | 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 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 | 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 | The Venu 4 has no LTE variant; Garmin's cellular models sit in other product lines. |
| Water & Dust Rating | 5 ATM (50 m) |
| Battery Replacement | Garmin does not sell a user or dealer battery-replacement service for the Venu line; out-of-warranty support is a discounted replacement unit. |
| Connectivity | Bluetooth, Wi-Fi, ANT+, NFC (Garmin Pay), Multi-band GNSS |
| Material | Stainless steel bezel with a polymer case and Corning Gorilla Glass 3 |
| Warranty | 12 months |
