OnePlus Watch 3: smartwatch with Wear OS and up to 16 days of battery life unveiled
This is a suave-looking smartwatch, which gets closer to a traditional timepiece than anything in the Apple, Samsung or Google stables. I don’t mind that there’s only one size – 47mm – but it might look out of place on particularly small or skinny wrists. It filled mine far more elegantly than the chunky, squircular Galaxy Watch Ultra, with a weigh that feels substantial.
On the design front, the Watch 3 is quite similar to the OnePlus Watch 2, with a few key changes. The OLED display is a smidge larger and brighter at 2,200 nits, and the bezels are notably smaller, though that’s partially because of a slight design tweak. The screen is spiffy to look at, especially with the new video watchface where you can upload your own clips.The casing is still stainless steel, but there’s a new titanium physical bezel, too.

The OnePlus Watch 3 keeps the sleek stainless steel design of its predecessor, with some notable upgrades. It has a rotating crown with an easy-to-grip texture and a titanium bezel surrounding the screen — reminiscent of the rotating bezels on the early Samsung watches that I loved. This one is thinner and stays in place, but I like how it elevates the design, making it look less like a giant circular 1.5-inch AMOLED display strapped to my wrist. The screen is bright and easy to see even in direct sunlight. The watch comes in silver or black, with rubber straps that are comfortable to wear all day and night.
Battery life has also been improved from 100 hours to 120 hours — or five days with regular use and the always-on display turned off. Turning on the AOD shortens that to roughly three days. That’s fairly typical for all flagship smartwatches these days. In a power-saving mode, you can get up to 16 days.

OnePlus says it’s managed to stuff a larger 631mAh battery in the Watch 3 using the same silicon nanostack battery as the OnePlus 13. Since it runs Wear OS 5, that should add some extra battery mileage.
OnePlus claims the Watch 3 can last five days on its default settings. That’s thanks to a large 631mAh battery and a dual-chipset system that uses its Snapdragon W5 processor to focus on powering app usage, while its BES2800 MCU Efficiency chip handles low-powered background tasks.
