OnePlus Watch 3 review

The OnePlus Watch 3 is for Android owners who like Wear OS but not the daily charging that usually comes with it. OnePlus rates the 46mm model at up to 5 days in Smart Mode and up to 16 days in Power Saver Mode, and says 10 minutes on the charger gives a full day. The 1.5-inch LTPO display sits under sapphire crystal inside a titanium alloy bezel, so it is built for daily knocks. Wear OS by Google brings watch faces, tiles, Google Maps and Google Wallet, though OnePlus notes that some Wallet features depend on country and device. Health tracking runs through the OHealth app, including a 60-second Health Check-In that gives insights into arterial stiffness, plus sleep tracking. The limits are compatibility and depth: it does not support iPhone, the app needs Android 9.0 or later with Google services, and it lacks the FDA-cleared heart features Apple documents. At $349.99 it costs more than the Pixel Watch 5 sale price.
