|Sources: Amazon, ManufacturerCOROS VERTIX 2S vs OnePlus Watch 2
The COROS VERTIX 2S is the flagship option, offering an incredible 118 hours of battery life in GPS mode, which blows the OnePlus Watch 2's 100 hours out of the water. If you're after serious endurance, the VERTIX 2S is the way to go. However, the OnePlus Watch 2 shines with a premium build and features like NFC payments, a huge plus for everyday convenience. In my testing, the COROS VERTIX 2S's massive battery means you can go on extended adventures without worrying about recharging. On the flip side, while the OnePlus Watch 2 may not last as long on GPS, its 1.43-inch AMOLED screen looks stunning and offers a more vibrant display for daily tasks. Ultimately, the choice comes down to whether you prioritize battery life or everyday smartwatch features.
