OnePlus claims the Watch 3 lasts up to five days (or 120 hours) on a single charge, and in my experience, that holds true -- I've only needed to charge it once a week. On top of that, it supports fast charging, so just 10 minutes plugged in gives you a full day of battery life.

Battery life can stretch even further with power-saving mode, but in my testing, I left it in smart mode while running and rowing about three times a week. OnePlus provides detailed battery life estimates based on factors like wireless status, message frequency, and exercise tracking, so be sure to check the product page for specifics. Still, it's refreshing to move beyond the typical one- to two-day battery cycle -- thanks to a large-capacity battery, silicon-carbon technology, and a dual-OS architecture.
2. You want a durable smartwatch
The Pixel Watch 3 is a sleek, minimalist smartwatch, but its design is dominated by curved glass that leaves the display exposed. In contrast, the OnePlus Watch 3 is built like a tank, featuring a sapphire crystal face with an 8+ rating on the Mohs hardness scale, a stainless steel case with a titanium bezel, IP68 dust and water resistance, a 50m water pressure rating, and MIL-STD-810H certification
3. Basic health and wellness data is all you need
GPS accuracy is excellent, and the heart rate sensor performs reliably in most conditions. The OnePlus Watch 3 supports a wide range of sports, even offering advanced metrics for some activities. However, you can't customize the data screens during workouts, so you're limited to the information OnePlus chooses to display.
