If you're looking for a new smartwatch to use with an Android phone, a OnePlus model might be on your mind. But with OnePlus confirming that it will exit the U.S. market, you probably want to go another route. That said, the OnePlus Watch 3 is a fantastic device with incredible battery life. In our review, we loved the stylish design, the robust health tracking, and, most notably, the dual-processor approach to preserving battery life. Big brands like Garmin, Samsung, and Google, as well as smaller brands like Amazfit, all have great alternatives to consider.
