Watch 3

The OnePlus Watch 3 lasts about five days with everything on, the best battery of any Wear OS watch.

Buying call

Buy the OnePlus Watch 3 if you have an Android phone and want a Wear OS watch that doesn't need daily charging: reviewers measured about five days with all features on, and its fitness tracking improved with no subscription. It has customizable buttons and takes standard 22mm straps. Skip it if you want ECG, which isn't available in the US, or a small watch, since it comes in one big size. There's no LTE model, and OnePlus promises only three years of updates.
