2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch 7 vs Garmin Venu 3
The Samsung Galaxy Watch 7 is the premium option here, boasting a powerful 3nm Exynos W1000 chip for faster performance. However, if battery life is your priority, the Garmin Venu 3 shines with up to 14 days of usage compared to the Galaxy Watch 7's daily charging requirement. In real-world use, the Galaxy Watch 7's advanced health features like ECG and Sleep Apnea detection are appealing, but they only work with Samsung phones. The Venu 3, with its bright 1.4" AMOLED display, is more versatile for daily wear, making it an excellent choice for those who want a stylish smartwatch that lasts longer on a single charge.
