Xiaomi Smart Band 11 Active Debuts With 21-Day Battery Life

Xiaomi has expanded its wearable lineup with the global release of the Smart Band 11 Active. Positioned as an affordable fitness tracking solution, the device’s design had previously surfaced via early leaks from Roland Quandt and WinFuture.

What Is the Xiaomi Smart Band 11 Active?

The device features a minimalist design and is available in three colors: Black, Grey, and Pomelo Pink. It boasts a compact body measuring 43.5 x 25.8 x 10.2 mm and weighs just 18g without the strap.

Unlike more advanced models such as the Smart Band 10, this version utilizes a TFT display. The screen measures 1.47 inches with a resolution of 172 x 320 pixels, providing a pixel density of 247 PPI. The tracker features 5 ATM water resistance, though the manufacturer advises against using it for diving, saunas, or hot showers.

Technical Specifications and Capabilities

Equipped with a modern PPG sensor, the device offers heart rate monitoring, blood oxygen (SpO2) tracking, sleep tracking, stress monitoring, and women’s health tracking. It supports 50 workout modes and is compatible with both Android and iOS.

Battery Life Conditions

A key highlight is the battery performance. The manufacturer claims up to 21 days of usage under light scenarios. The integrated battery has a capacity of 300 mAh.

Under more active usage, the band provides 8 days of battery life. Active usage includes the following functions and actions:

• Sleep monitoring (with breathing quality tracking) up to 8 hours per night;
• 24/7 heart rate monitoring every minute;
• Two manual SpO2 measurements per day;
• Stress monitoring;
• Up to 200 notifications, 15 incoming calls, and 3 alarms per day;
• Screen activation via wrist lift (up to 500 times per day);
• One app synchronization per day;
• 90 minutes of exercise per week.

These performance metrics are based on factory settings and standard static watch faces.

Price and Availability

The current official price is 139 PLN (~$38, equal to €35 or 1585 UAH). In the Eurozone, the estimated price is €40 ($40 / 1810 UAH). Pricing details are summarized below:

Is the Smart Band 11 Active Worth It?

This model is aimed at users seeking a simple and reliable tracker for activity monitoring with infrequent charging. Given its budget segment, the Smart Band 11 Active lacks the AMOLED screen found in higher-end models, but it excels in terms of the price-to-battery-life ratio.
