The Xiaomi Watch 2 features a 1.43″ OLED/AMOLED touchscreen with a resolution of 466 x 466 pixels and a pixel density of 326 ppi, delivering a sharp and clear visual experience on the wrist. Always-On Display is supported, and the watch band is replaceable, offering some flexibility in personalisation. The case measures 47.5 mm in height, 45.9 mm in width, and 11.8 mm in thickness, with a total volume of 25.73 cm³ and a lightweight body of just 36.8 g. Water resistance is rated at 5 ATM, corresponding to a waterproof depth of 50 metres, making it suitable for swimming and water exposure. The display does not use branded damage-resistant glass or sapphire glass, and the watch is not designed for children.

The Xiaomi Watch 2 is equipped with a comprehensive sensor suite that includes a heart rate monitor, a pulse oximeter for blood oxygenation tracking, and a body temperature sensor for continuous health monitoring. Built-in GPS enables accurate location tracking without relying on a paired phone, while an accelerometer, gyroscope, compass, and barometer round out the motion and environmental sensing capabilities. The watch does not include a cadence sensor or a perspiration monitor.

The Xiaomi Watch 2 covers a wide range of everyday activity tracking, recording steps, distance, pace, and elevation, while also offering automatic activity detection and exercise tagging for convenient workout logging. Sleep tracking is supported alongside detailed sleep reports, giving users a clearer picture of their rest patterns. A built-in route tracker helps map outdoor sessions, and calorie intake tracking adds a nutritional dimension to the overall health picture. The watch does not include a multi-sport mode, a swimming stroke counter, and is not designed for diving or golf.

The Xiaomi Watch 2 connects to Android devices only, with no iOS compatibility, and relies on Bluetooth 5.2 alongside Wi-Fi for wireless communication. It includes NFC for contactless functionality and supports the Galileo satellite navigation system for positioning. The watch does not have a cellular module, so it requires a paired phone for data connectivity, and it does not support ANT+.

The Xiaomi Watch 2 is powered by a rechargeable 495 mAh battery with a rated battery life of 2.2 days, and it charges fully in just 0.75 hours via a wired connection. The battery is neither removable nor solar-assisted, and the watch does not support wireless charging.

The Xiaomi Watch 2 offers a broad set of practical features, including wrist notifications, vibrating alerts, a silent alarm, a stopwatch, and voice commands for hands-free interaction. It can answer calls and handle call control directly from the wrist through its single built-in microphone, and a phone-finder function helps locate a paired device when needed. Heart rate monitoring extends to resting heart rate measurement and fast/slow heart rate notifications, though irregular heart rate warnings and ECG technology are not available. Fall detection adds a layer of safety, while a remote camera shutter function provides a convenient way to trigger a phone's camera remotely. On the hardware side, the watch carries 2 GB of RAM and 32 GB of internal storage, and it comes with a one-year warranty. Smart alarm is not supported.

The companion app for the Xiaomi Watch 2 is free to download and completely ad-free, though it does require an account to use. It supports a wide range of tracking and management tools, including calorie burn counting, water intake, weight, BMI, temperature tracking, and an exercise diary covering 161 exercises. Activity reports, inactivity alerts, and goal setting help users stay on top of their fitness progress, while an achievements system adds a motivational element. The app also supports calendar sync, music playback, widgets, and personalisation options, making day-to-day use more flexible. Coaching and route support are not available, nor is data export via email or a barcode scanner function.

The Xiaomi Watch 2 includes a battery level indicator and supports passcode protection for basic security. It is not compatible with Windows or Mac OS X, has no external memory slot for storage expansion, and does not feature a 3.5 mm audio jack.
