OnePlus Watch 3 Leaks: Thinner Design, Larger Battery

A new FCC listing has revealed more details about the upcoming OnePlus Watch 3, including its dimensions and battery size. The watch will be slightly thinner than its predecessor at 11.75mm (vs. 12.1mm for the Watch 2) but roughly the same overall size at 46.6 x 47.6mm. Perhaps most notably, though, is that the new smartwatch appears set to include a much bigger battery, with rated and typical capacities of around 631-648 mAh, up from the 500 mAh cell in the last-gen model.
