Bright 1.43-Inch AMOLED Display

The Xiaomi Watch S4 features a 1.43-inch AMOLED display with a sharp 466 × 466 resolution and 326 PPI pixel density. Text, activity data, notifications and watch faces remain clear and easy to read throughout the day.

Its display supports a 60Hz refresh rate for smoother scrolling and interface transitions. Brightness reaches up to 1500 nits in high-brightness mode and up to 2200 nits at peak, helping improve visibility in bright outdoor conditions.

Xiaomi has also included moisture-resistant touch control. This feature helps reduce unintended screen operations caused by water droplets, making the interface more practical during workouts and outdoor activities.

Premium Design with Interchangeable Bezels

Unlike many conventional fitness watches, the Xiaomi Watch S4 uses an interchangeable bezel design inspired by traditional wristwatches. Users can change compatible bezel and strap kits to create a different appearance for work, exercise or formal events.

The aluminium alloy frame provides a polished, premium finish without making the watch unnecessarily heavy. A rotating crown on the side allows you to browse widgets, notifications and application menus more naturally.

The standard watch is available in selected colours, including Black, Silver and Rainbow. Colour and strap availability may vary according to stock.

Bluetooth Calling from Your Wrist

The built-in speaker and dual microphones allow the Xiaomi Watch S4 to support Bluetooth calling when connected to a compatible smartphone.

You can answer or make regular calls directly from your wrist without taking out your phone. This is particularly useful while driving, exercising, working or carrying shopping bags.

The watch must remain connected to the smartphone through Bluetooth for calling. Calls made through certain third-party applications may not be supported.

One-Tap Health and Wellness Insights

The Xiaomi Watch S4 brings major wellness indicators together in one convenient interface. Its one-tap measurement feature can assess several metrics and generate a quick wellness overview in approximately one minute.

Supported monitoring features include:

• Heart rate monitoring

• Blood oxygen saturation monitoring

• Advanced sleep monitoring

• Stress monitoring

• Breathing exercises

• Daily activity tracking

All-day blood oxygen, stress and advanced sleep monitoring may need to be activated manually through the Mi Fitness application.

The Xiaomi Watch S4 is a consumer wellness device and not a medical instrument. Its readings should not be used to diagnose, treat or prevent a medical condition.

More Than 150 Sports Modes

With over 150 sports and workout modes, the Xiaomi Watch S4 can record a wide range of indoor and outdoor activities.

It is suitable for:

• Outdoor running

• Treadmill workouts

• Walking

• Cycling

• Strength training

• Swimming

• Hiking

• Skiing

• General gym exercises

The watch also includes running courses designed for different fitness goals, including beginner training, endurance improvement and weight-management workouts.

Selected running modes can analyse metrics such as ground contact time, vertical movement and running form, providing more detailed information than basic step tracking.

Dual-Frequency GNSS for Outdoor Tracking

The Xiaomi Watch S4 includes L1 and L5 dual-frequency GNSS, allowing the watch to receive positioning data through two frequency bands.

It supports five major satellite systems:

• GPS

• Galileo

• GLONASS

• BeiDou

• QZSS

The built-in GNSS system allows users to record outdoor routes without relying entirely on their smartphone’s positioning system. It is particularly useful for running, cycling, hiking and other outdoor training sessions.

Up to 15 Days of Battery Life

A 486mAh battery provides up to 15 days of typical usage, depending on enabled features, notification frequency, Bluetooth calls, display settings and workout tracking.

The watch also supports fast charging. According to Xiaomi’s laboratory testing, approximately five minutes of charging can provide up to two days of usage under defined test conditions.

Actual battery life may be lower when using features such as:

• Always-on display

• Continuous blood oxygen monitoring

• High-precision sleep tracking

• Frequent Bluetooth calling

• Regular GPS workouts

• Maximum screen brightness

Even with active daily use, the larger battery makes the Xiaomi Watch S4 a practical option for users who do not want to recharge their smartwatch every night.

5ATM Water Resistance

The Xiaomi Watch S4 carries a 5ATM water-resistance rating, equivalent to water pressure at a depth of approximately 50 metres under laboratory conditions.

It can be used for swimming in pools, near-shore swimming and other shallow-water activities. However, it should not be worn while diving, taking hot showers or using a sauna.

Water resistance is not permanent and may gradually decrease because of regular wear, accidental impact or exposure to unsuitable conditions.

Xiaomi HyperOS 2 and Smart Connectivity

The watch operates on Xiaomi HyperOS 2 and connects to smartphones through Bluetooth 5.3. Users can receive notifications, access fitness records, manage watch settings and synchronise health information through the Mi Fitness app.

On supported Xiaomi smartphones running the required HyperOS version, the watch may also provide access to Xiaomi Smart Hub features for managing compatible connected devices.

Some smart functions depend on the smartphone model, operating system, application version and regional availability.
