Upon unboxing the Xiaomi Watch S4, you can notice a faint odor. This is a result of the material properties of the plastic components and packaging materials, which can emit a slight smell after being sealed during storage and transportation. Rest assured, the odor is harmless and does not indicate any safety or quality issues.
To address this, allow the watch and its packaging to air out in a well-ventilated area. The smell will naturally dissipate over time. This phenomenon is common with new electronic products and does not affect the watch’s functionality or performance.
