2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch6 Classic (47mm, Bluetooth) vs Samsung Galaxy Watch 8 Classic
The Samsung Galaxy Watch 8 Classic takes the lead in battery life, lasting up to 49 hours compared to the Galaxy Watch6 Classic's 40 hours. If you're tired of charging daily, this extended battery is a game-changer for busy lifestyles. In real-world use, the 1.5-inch Super AMOLED display on the Galaxy Watch6 Classic shines with vibrant colors, but the Galaxy Watch 8 Classic's 3,000 nits brightness is impressive for outdoor visibility. However, the smaller 1.34-inch screen may feel cramped for some users, especially in the larger 46mm case. The trade-off? Key specs: Weight: 2.08 oz vs 2.24 oz and Storage: 16 GB vs 64 GB.
