Features and Performance: A Mixed Bag?
Does It Deliver on Power?
Under the hood, the OnePlus Watch 3 boasts impressive specs, including a Snapdragon W5 Gen 2 chipset and Wear OS with a custom UI.
- Battery Life: While advertised as lasting up to 10 days, I found it lasted about 7 days with regular use, which is still impressive.
- Fast Charging: Warp Charge delivers on its promise—15 minutes for a day’s power.
- Smooth Navigation: The rotating crown is a welcome addition, making navigation seamless, though it’s not essential for touch-savvy users.
Personal Take: The watch is snappy and responsive, but the lack of a vast app ecosystem holds it back from being a true smartwatch powerhouse.
Health and Fitness Tracking: A Standout Feature
The health tracking capabilities of the OnePlus Watch 3 are where it truly shines. With advanced sensors, it offers detailed insights into your wellness.
- Heart Rate and SpO2 Monitoring: Both are highly accurate and consistent.
- Sleep Tracking: The data feels actionable, with detailed breakdowns that help improve sleep quality.
- Workout Modes: The 110+ modes ensure there’s something for everyone, from casual walkers to HIIT enthusiasts.
- GPS Accuracy: The dual-frequency GPS is a game-changer for outdoor runners.
Real-World Story: I tested the running mode on a trail, and the GPS was spot-on, even under dense tree cover. However, swimming tracking wasn’t as accurate.
Connectivity and Ecosystem Integration
Staying Connected Made Easy
The OnePlus Watch 3 integrates beautifully with the OnePlus ecosystem, making it a breeze for existing OnePlus users.
- Bluetooth Calling: Clear and reliable.
- Music Control: Syncing playlists is easy, though offline Spotify support is missing.
- Smart Notifications: Handy but could use more customization options.
Personal Take: While the ecosystem integration is seamless, the smartwatch’s limited app compatibility compared to competitors like the Galaxy Watch 6 is a drawback.

I am confused –
“Does the OnePlus Watch 3 support third-party apps? A: It offers limited support via Wear OS, but app options are fewer than competitors.” —> only the apple store has a better app options and that is locked to iPhone so not an option for android users – so which of its competitors – garmin, huawei, amazfit, suunto, polar and coros offer a better app store than wear os?
My understanding is that you are either running full wear os or you can switch into their own operating system – switch back and forth as much as you want – and yes when in their own os you are limited as can’t run wear os apps, but if running wear os at the time there is not impact to wear os eco system – or am I wrong about it?
When running Wear OS, the OnePlus Watch 3 has a better app store (Google Play Store) than Garmin, Huawei, Amazfit, Suunto, Polar, and Coros. These competitors have smaller, less diverse app selections focused on their specific strengths (fitness, sports). Your understanding of the OnePlus Watch 3’s dual OS (full Wear OS and a proprietary OS with limited apps) and the impact on the Wear OS ecosystem is largely correct.
