Garmin Venu 3 vs Samsung Galaxy Watch 4 Classic
The Verdict
Garmin Venu 3 and Samsung Galaxy Watch 4 Classic target different user priorities. Garmin excels with superior battery longevity, delivering up to 14 days in smartwatch mode versus Samsung's realistic 22 hours, making it ideal for fitness enthusiasts who prioritize extended wear between charges. Garmin adds skin temperature monitoring, a useful health metric Samsung omitted. Samsung counters with cellular connectivity for standalone calls and messages, something Garmin lacks entirely. The Galaxy Watch 4 Classic features a larger case option at 46mm with 450 x 450 resolution matching Garmin's density, plus superior durability with IP68 rating and MIL-STD-810G certification. Display brightness and outdoor visibility favor both AMOLED panels roughly equally. Samsung's Wear OS 3.0 provides broader app compatibility and deeper Google ecosystem integration, while Garmin's proprietary OS feels more streamlined for sports tracking. Price difference of $100 gives Samsung the value edge for casual users, but Garmin's two-week battery life justifies its premium for serious athletes who resent daily charging. Both handle ECG, SpO2, and sleep tracking competently. Choose Garmin if battery endurance and comprehensive health metrics matter most, or select Samsung for cellular independence and broader software options.
