Xiaomi Watch S4 47mm

Round Xiaomi smartwatches can be classified in the mid-price range, though within the brand's series, they are considered more of an advanced-level device. This status is confirmed by some features, such as the Bluetooth calling function, which uses two microphones to provide effective noise cancellation and good voice audibility for the caller. Also noteworthy is the gesture control support and pleasant features for runners, including a route planner.

The Xiaomi Watch S4 smartwatch features a colorful 1.43-inch touchscreen display with a 60 Hz refresh rate and increased maximum brightness of up to 2200 nits (an ambient light sensor is included for auto-adjustments). The model operates on the proprietary HyperOS interface, supporting 150 fitness modes. The sensor set includes a GPS module, compass, barometer, and altimeter, while health monitoring tools include a heart rate monitor, pulse oximeter, sleep monitoring, and stress level tracking. The built-in lithium-polymer battery of 486 mAh is designed to ensure a good level of autonomy: the gadget can run from 5 days (with the Always-on Display active) to 15 days in regular use scenarios. The aluminum case and stainless steel bezel, decent water resistance (up to 5 ATM), and a small weight of 45 grams deserve special mention.
