2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerGarmin Forerunner 965 vs Samsung Galaxy Watch6 Classic (47mm, Bluetooth)
The Garmin Forerunner 965 is the flagship option here, and it truly shines with a staggering 23-day battery life compared to the Samsung Galaxy Watch6 Classic's 40 hours. If you're focused on maximizing battery for long runs or multi-day adventures, the Garmin is the smarter buy. In real-world use, Garmin's 1.4" AMOLED display is bright and easy to read, but Samsung's 1.5" Super AMOLED gives a slightly better visual experience. However, you'll need to charge the Galaxy Watch6 daily, whereas the Forerunner can last weeks without needing a plug. That's a game-changer if you're often on the go.
