Xiaomi Watch S4 Silver

Key features of the Xiaomi Watch S4 Silver smartwatch

Precisely crafted AMOLED display with a fine resolution

The AMOLED display of the Xiaomi Watch S4 is a joy to behold. Everything will be perfectly visible on the 1.43" display, and thanks to the AMOLED technology you can look forward to a more colourful and smoother picture. The Xiaomi Watch also excels in readability even in direct sunlight, so you won't miss any incoming notifications. The brightness reaches a maximum value of 2200 nits, and the display's glow can automatically adapt to the ambient conditions. The watch display has a resolution of 466 × 466px with a fineness of 326 PPI and a refresh rate of 60Hz.

Up to 15-day battery life

Inside the Xiaomi Watch S4 is a 486mAh battery that uses AI algorithms to optimise power consumption. In smartwatch mode, the battery life is around 15 days. If you want to charge the watch quickly, just 5 minutes on the charger will give it enough power for up to 2 days of normal use.

Xiaomi Watch S4 uses multi-system GPS and has great battery life

Xiaomi Watch S4 is equipped with a GNSS chip that supports all five key positioning systems: GPS, BeiDou, GLONASS, Galileo, and QZSS. The chip also features enhanced advanced algorithms for faster and more accurate positioning.

The Xiaomi smartwatch offers more than 150 sports modes

Don't be afraid to get active and start exercising or doing other activities. With the Xiaomi Watch S4, you can accurately measure your performance parameters—heart rate, average heat, or calories burned. You'll have over 150 sports modes to choose from. Of course, it has a water-resistant design up to 5 ATM, so you can go swimming without worry and measure your swimming performance. The Xiaomi Watch S4 smartwatch gives you access to professional courses and systematic workouts. Using advanced sensors, the smartwatch can automatically recognise key running technique indicators (vertical ratio, vertical amplitude, or ground contact time). With the Xiaomi Watch S4, you can also record the duration, distance, and average speed of every ski/snowboard run. You can find more detailed information in the app on the results page. You will also be able to see a map of your ski trail.

Xiaomi Watch S4 has a sophisticated PPG biosensor

The Xiaomi Watch S4 performs 24-hour heart rate monitoring and can monitor blood oxygen levels (SpO₂). The PPG biosensor with upgraded hardware and algorithms ensures more accurate heart rate measurement during low and very high-intensity activities. If you are stressed, the Xiaomi Watch S4 can offer you breathing exercises to help you calm down. You can adjust the blood oxygen measurement interval—keep it all-day, or set your preferred interval. The Xiaomi Watch S4 more accurately records your night's sleep with all its phases, while also capturing occasional short naps during the day. With the Xiaomi watch, you can identify your sleep pattern and improve your sleep habits.

Handle calls from your paired phone from your wrist

Connect the Xiaomi Watch S4 to your phone via Bluetooth and you can handle incoming calls from your wrist. The watch is equipped with a microphone and a speaker. This can also be used in an emergency, as a triple press of the side button in the bottom right corner will dial your emergency contact. For this function to work, you need to connect the Xiaomi Watch S4 to your mobile phone via Bluetooth and set an emergency contact in the app. A notification can also be sent to the contact automatically if you do not respond to the prompt that you are okay within 60 seconds.

Xiaomi Watch S4 enables contactless payments

Thanks to NFC technology, you can use contactless payments and pay with your Xiaomi watch via Mastercard and Visa cards. This feature is available at selected banks and must be verified on the manufacturer's or bank's website.

Mi Fitness app

Always have fresh and detailed information about your health or activity at hand. The companion Mi Fitness app, after pairing with the Xiaomi Watch S4 smartwatch, stores all the measured data, which you can then view clearly. It now also supports Health Connect and training apps like Strava or Suunto.
