The listing discloses that the OnePlus Watch 2 will feature a 500 mAh battery, positioning it as a standout in the smartwatch market for its potential 100 hours of battery life on a single charge.

This battery capacity places the OnePlus Watch 2 ahead of some competitors in terms of battery size, such as Google's Pixel Watch 2 and the Galaxy Watch 6. Despite not breaking groundbreaking records compared to previous models like the Galaxy Watch 5 Pro, the OnePlus Watch 2 is set to provide an extended battery life experience for users.

Furthermore, with the information provided by the FCC listing, it becomes evident that the OnePlus Watch 2 will carry the model number OPWWE231 and utilize a pin-based charging system with a charging speed of 10W. The absence of LTE mention indicates a potential absence of this feature in the initial model or a pending FCC approval for an LTE variant.

As the tech community eagerly anticipates the OnePlus Watch 2, questions remain about the software it will run. Speculation arises on whether OnePlus will utilize Wear OS to achieve the boasted 100 hours of battery life or introduce a custom interface like Samsung's Galaxy Watch series. Nevertheless, with its promising battery capacity and efficient software, the OnePlus Watch 2 is shaping up to be a noteworthy contender in the smartwatch market.
