The Xiaomi Redmi Watch 6 Active is the accessible mid-range entry in the Redmi Watch 6 lineup — positioned between the budget Lite and the full-featured standard Watch 6 — and the model that concentrates the most everyday-relevant smartwatch features into the thinnest profile at this price point. The 9.9mm thickness makes it one of the slimmest smartwatches in its category, and at 26g without the strap it is light enough to wear continuously through the day and at night for sleep tracking without the weight becoming noticeable.

The 1.85-inch AMOLED display is the most significant hardware step up from budget LCD smartwatches. AMOLED produces absolute blacks (each pixel turns off independently when showing black rather than a backlit LCD panel showing very dark grey), which makes watch faces with dark backgrounds appear to float on a black surface, dramatically increases contrast, and reduces power consumption in dark-dominant watch face designs. The 390×450 resolution at 322 PPI delivers sharp text, smooth icon rendering and readable fitness data at a glance without the pixelation visible on lower-resolution displays. Peak brightness reaches 1200 nits — sufficient for screen readability in direct outdoor sunlight, which is the real-world test that most budget smartwatch displays fail. The screen supports Always-On Display (AOD), which shows a reduced-power clock face continuously without requiring a wrist raise or button press to check the time — the feature that, in day-to-day use, makes a smartwatch actually function like a watch rather than requiring an interaction for the most basic task.

Bluetooth calling allows the watch to connect to a paired phone’s call function and handle incoming and outgoing calls directly from the wrist using the watch’s built-in speaker and microphone — so calls can be answered, conducted and ended without the phone leaving a bag or pocket. The built-in speaker and microphone enable this standalone without any accessory. The Bluetooth 5.3 connection handles both the calling audio and the watch’s data sync with the Xiaomi Sports Health app simultaneously.

Health monitoring runs continuously: all-day heart rate monitoring with abnormal heart rate alerts, all-day SpO₂ (blood oxygen saturation) monitoring, all-day stress monitoring with a guided breathing exercise function for stress relief, and advanced sleep monitoring that tracks sleep stages, duration and quality throughout the night and records naps. The health sensors include an optical heart rate sensor, accelerometer and the SpO₂ sensor. 140+ sports modes cover running, walking, cycling, swimming (IP68 protects the watch to submersion depth), gym training, yoga, ball sports and more — each mode records relevant metrics for that sport and syncs to the app after the session.

One important specification to understand for outdoor sports use: the Watch 6 Active does not have built-in GNSS/GPS. The standard Redmi Watch 6 has built-in multi-system GNSS for phone-free route tracking; the Watch 6 Active uses the connected phone’s GPS when recording outdoor runs, rides and hikes. For users who always carry a phone during workouts this distinction has no practical effect — the phone provides the route and the watch provides the heart rate, step count and sports tracking data. Users who want to leave the phone at home and track routes independently should consider the standard Redmi Watch 6 instead. IP68 confirmed for submersion protection beyond the typical IP54 splash resistance of entry-level smartwatches. 470mAh battery delivers up to 18 days on light use, 12 days on normal use and 6 days with AOD continuously active. Magnetic charging cable included. Xiaomi HyperOS. Compatible with Android 8.0+ and iOS 14.0+. Available in Midnight Black, Matte Silver and Sunset Orange.
