|Sources: Amazon, ManufacturerOnePlus Watch 2 vs Samsung Galaxy Watch 8 Classic
The OnePlus Watch 2 crushes the Samsung Galaxy Watch 8 Classic when it comes to battery life: 100 hours vs 49 hours. If you're tired of charging your smartwatch daily, the OnePlus is the premium option for you. In real-world use, that 100-hour battery means you could go an entire week without worrying about a charge. On the flip side, the Galaxy Watch 8 Classic offers a smaller display at 1.34 inches and is significantly heavier at 2.24 oz, which might not feel great on your wrist during all-day wear.
