Xiaomi Watch S4

Round smartwatches from Xiaomi can be classified in the mid-price range, although within the brand's model lineup, it is more of an advanced device. This status is confirmed by some features, such as the Bluetooth call function, which uses two microphones to ensure effective noise cancellation and good voice audibility for the interlocutor. Gesture control support and pleasant features for runners, including a route planner, are also noteworthy.

The Xiaomi Watch S4 smartwatch features a 1.43-inch color touchscreen display with a 60 Hz refresh rate and increased maximum brightness of up to 2200 nits (with a light sensor for auto-adjustments). The model operates under the proprietary HyperOS shell and supports 150 fitness modes. The sensor set includes a GPS module, compass, barometer, and altimeter, and for health monitoring, there is a heart rate monitor and pulse oximeter, sleep monitoring, and stress level tracking. The built-in lithium-polymer battery of 486 mAh should provide a good level of autonomy: without recharging, the gadget will work from 5 days (with active Always-on Display) and up to 15 days in standard usage scenarios. The aluminum case and stainless steel bezel, worthy water resistance (up to 5 ATM), and lightweight of 45 grams deserve special mention.
