The smartwatch market is increasingly competitive, with both Oppo and Xiaomi offering compelling Wear OS options. Both the Oppo Watch S and the Xiaomi Watch 2 Pro utilize Qualcomm's Snapdragon W5 platform, promising improved battery life and performance over previous generations. However, a crucial distinction – the use of the Snapdragon W5 Gen 1 in the Oppo Watch S versus the W5+ Gen 1 in the Xiaomi Watch 2 Pro – dictates which watch ultimately delivers a superior user experience.
🏆 Quick Verdict
For most users, the Xiaomi Watch 2 Pro emerges as the better choice. The Snapdragon W5+ Gen 1 offers a tangible performance advantage, translating to smoother animations and quicker app loading times. While both watches share a similar design language and Wear OS experience, the Xiaomi’s chipset provides a more future-proof and responsive platform.

Display Comparison
Detailed display specifications are unavailable, but both watches likely employ AMOLED panels for vibrant colors and good outdoor visibility. The key differentiator will be peak brightness and potentially LTPO support for adaptive refresh rates. Given Xiaomi’s recent smartphone displays, the Watch 2 Pro likely boasts a higher peak brightness, improving readability in direct sunlight. Bezels are expected to be minimal on both, contributing to a modern aesthetic. Color accuracy will depend on calibration, but both brands typically deliver acceptable results.
Camera Comparison
Neither watch is expected to feature a camera, a trend increasingly common in modern smartwatches. The focus is shifting towards health and fitness tracking, where a camera offers limited utility.
Performance
The core difference lies in the chipset. The Xiaomi Watch 2 Pro’s Snapdragon W5+ Gen 1 represents a refinement of the Snapdragon W5 Gen 1 found in the Oppo Watch S. The ‘+’ variant typically indicates higher clock speeds and improved efficiency. While both are built on a 4nm process, the W5+ Gen 1’s architecture allows for more sustained performance under load. This translates to faster app launches, smoother animations, and a more responsive user interface on the Xiaomi Watch 2 Pro. RAM specifications are currently unknown, but LPDDR5x is expected on both, further contributing to performance.
Battery Life
Battery capacity details are missing for both devices. However, the Snapdragon W5+ Gen 1 in the Xiaomi Watch 2 Pro is inherently more power-efficient than the W5 Gen 1 in the Oppo Watch S. This efficiency gain, combined with optimized software, should result in longer battery life for the Xiaomi Watch 2 Pro. Charging wattage is also unknown, but faster charging speeds would further mitigate any potential capacity differences. Expect both to support wireless charging.
Buying Guide
Buy the Oppo Watch S if you prioritize a slightly more established Wear OS ecosystem within the Oppo brand and are seeking a solid, reliable smartwatch experience at a potentially lower price point. Buy the Xiaomi Watch 2 Pro if you demand the best possible performance from a Wear OS smartwatch, value the incremental improvements offered by the Snapdragon W5+ Gen 1, and appreciate a more modern chipset for long-term software support.
Frequently Asked Questions
❓ What real-world difference will I notice between the Snapdragon W5 Gen 1 and W5+ Gen 1 in daily use?
The difference won't be dramatic for basic tasks like timekeeping and notifications. However, the W5+ Gen 1 in the Xiaomi Watch 2 Pro will be noticeably smoother when launching apps, scrolling through complex watch faces, and using more demanding features like voice assistants. It also provides headroom for future software updates and feature additions.
❓ How does the chipset impact the longevity of the watch in terms of software updates?
A more powerful and efficient chipset like the Snapdragon W5+ Gen 1 allows for more complex software features and optimizations. This typically translates to longer software support from the manufacturer, ensuring your watch remains secure and up-to-date with the latest Wear OS features for a longer period.
❓ Is the difference in performance significant enough to justify a potential price increase for the Xiaomi Watch 2 Pro?
That depends on your usage. If you're a power user who frequently uses apps, relies on voice assistants, or plans to keep the watch for several years, the performance boost of the W5+ Gen 1 is worth the extra investment. However, if you primarily use the watch for basic notifications and fitness tracking, the Oppo Watch S may suffice.
