Summary

The metal shell + HD screen design makes its texture a level higher than its predecessor; richer and more accurate sports health monitoring to meet the needs of users in a variety of scenarios; with the support of HyperOS, Redmi Watch 4 not only lasts longer, but also has more convenient interconnectivity with other smart devices. Overall, as the fourth generation of the Redmi Watch product line, the overall performance of Redmi Watch 4 is still remarkable.

Of course, Redmi Watch 4 is not without its drawbacks. The inability to install third-party software and the lack of commonly used software such as WeChat and Maps also puts it some distance from the first-tier Android smartwatch experience. But overall, the Redmi Watch 4 experience at this price point is considered top-notch. In the future, empowered by HyperOS, I hope Redmi Watch can bring us more over-the-top experiences.
