Smart Features: A Mixed Bag
The Watch S3 mirrors notifications from your phone, allowing you to stay connected without constantly checking your device. It also features a microphone and speaker for call handling, although sound quality is best reserved for emergencies. The NFC wallet supports Xiaomi Pay, but its compatibility is limited to specific Mastercards. One major downside is the lack of third-party app support, restricting the smartwatch's versatility compared to competitors.

Sleep and Wellness Tracking
The redesigned sleep app on the Galaxy Watch6 provides detailed insights directly on the watch. It tracks various sleep metrics, including skin temperature and blood oxygen levels, helping users improve their sleep quality with personalized coaching based on their sleep patterns.
Customization: Tailor Your Look
One of the standout features of the Xiaomi Watch S3 is its customizable bezels and straps. This unique design element allows users to change both the bezel and strap, effectively transforming the watch's appearance. With over 100 watch faces to choose from, users can tailor the watch to match their outfit or mood, making it a versatile accessory.

Conclusion: A Strong Contender in the Budget Segment
The Xiaomi Watch S3 is an excellent option for those seeking a premium smartwatch experience at an affordable price. Its impressive battery life, robust health tracking features, and customizable design make it a standout choice. However, the limitations in app compatibility and software polish might be a deal-breaker for some. Overall, the Watch S3 offers great value and is a solid choice for anyone in the market for a new smartwatch.
