A battery life champion you can already get at a nice discount
Even better, entering this promotional campaign will see one lucky contestant receive a free OnePlus Pad 2 and two other winners enter into possession of complimentary OnePlus Buds Pro 3.

That’s primarily due to a significant upgrade in what was already the Watch 2’s strongest department. Yes, last year’s mind-blowing 100-hour battery life promise is set to… blow your mind even harder, jumping to no less than five days, or 120 hours.
Like its predecessor, the OnePlus Watch 3 aims to achieve that competition-crushing number by combining Wear OS with a more frugal proprietary operating system for those situations when you might not need to access the device’s most sophisticated features.
On top of that, the new smartwatch will use two chips as well, leveraging the Snapdragon W5 for “performance” use cases and a new BES2800 MCU for energy-efficient tasks. Perhaps most importantly, the OnePlus Watch 3 will also increase the Watch 2’s actual battery size from 500 to 631mAh.
More functionality, more durability, still a lot of unanswered questions
Depicted in “Emerald” and “Obsidian” colorways, the undeniably gorgeous OnePlus Watch 3 certainly looks similar to the “Radiant” and “Black” OnePlus Watch 2 at first glance. But that large crown at the side promises to, well, actually do something this time around, allowing for more intuitive UI navigation and thus adding a much-needed touch of extra functionality to an already solid value package.
The rotating crown sits on a titanium alloy bezel with a “robust PVD” coating, which obviously aims to improve both the durability and elegance of the all-steel OnePlus Watch 2 by pairing with a familiar stainless steel case.

The actual case size and the screen size are only two of the question marks still hovering over the OnePlus Watch 3 (at least officially), and we also don’t yet know if the health monitoring tool set will be improved or expanded in any significant way.
