Fitbit Versa 3 vs Samsung Galaxy Watch 4
The Verdict
Samsung Galaxy Watch 4 edges out the Fitbit Versa 3 with superior hardware and software capabilities, despite costing just $20 more. The Galaxy Watch 4's Super AMOLED display offers sharper visuals with 396x396 resolution (40mm) compared to Versa 3's 336x336, while weighing significantly less at 25.9g versus 40g. Samsung includes ECG functionality, cellular connectivity options, and Wear OS 3.0's more robust app ecosystem, whereas the Versa 3 relies on Fitbit's more limited operating system. Battery life favors Versa 3 with 6+ days versus Galaxy Watch 4's typical 20 hours (up to 40 in battery saver mode), making it better for extended trips without charging. Both track sleep, heart rate, and SpO2 levels, and both feature NFC for contactless payments. Fitbit Versa 3 suits users prioritizing battery longevity and simplicity, while Galaxy Watch 4 appeals to Android users wanting deeper smartwatch features, better performance, and more health sensors. For most buyers, Galaxy Watch 4 delivers better overall value and capability.
