Major upgrade
While other Android smartwatches release more iterative annual updates, OnePlus knew it had a lot of fixes to make with the OnePlus Watch 3. This watch has significant upgrades across the board, primarily battery life, health data, and the display, but with more subtle improvements, too.
For
- Larger, smoother display with titanium bezel
- Redesigned health sensor with ECG, skin temp
- Crown is now functional
- Extra day of heavy-duty use
- Faster co-processor for background tasks
Against
- Still no smaller option, LTE
- ECG not available in North America
- Only two years of software support
Work in progress
OnePlus's first Wear OS watch made a splash because of its long battery life, but we found minor issues in areas like performance and health tracking that made it harder to recommend. This watch will still beat rivals for battery life and technically matches the Watch 3 for performance, but it's harder to recommend now.
For
- Excellent battery life only a day short of Watch 3
- Fast VOOC charging
- Same Snapdragon chipset, memory
- Equally durable design
Against
- Nonfunctional crown
- Unreliable last-gen MCU
- No ECG, skin temp
- Arguably less stylish
- Had documented issues with activity tracking
