Xiaomi has officially launched its new budget wearable, the Smart Band 11 Active, offering up to 21 days of battery life under light usage conditions, according to initial retail listings and industry reports. Available now in Poland for PLN 139 (approximately $38), the affordable fitness tracker provides robust health-tracking features, multi-sport modes, and cross-platform smartphone compatibility across three distinct color options.
Battery Life and Real-World Usage Metrics
The Smart Band 11 Active features a 300 mAh battery designed to deliver up to 21 days of power during light usage scenarios. Under heavier, feature-rich testing conditions, the device maintains an active battery life of roughly 8 days on a single charge.
Achieving that 8-day threshold requires specific operational parameters, according to retail and leak disclosures. Testing standards involve a fully charged device restored to factory settings utilizing a default static watch face. Advanced health tracking, including sleep breathing quality monitoring, operates during standard 8-hour nightly sleep cycles. Furthermore, all-day heart rate monitoring records measurements every minute alongside continuous all-day stress tracking.
Additional daily demands factored into the 8-day benchmark include manual blood oxygen saturation readings performed twice daily, alongside standard smartphone notifications consisting of 200 daily messages, 15 incoming calls, and 3 distinct alarms. Display activations via wrist-lifts are capped at 500 times per day alongside a single daily application sync and 90 minutes of weekly workout tracking.
Health Sensors and Multi-Sport Tracking Capabilities
Equipped with an onboard PPG sensor, the Smart Band 11 Active delivers comprehensive biometric oversight. The device tracks heart rates, blood oxygen saturation (SpO2) levels, sleeping patterns, stress metrics, and women’s health indicators, according to product specifications.
Athletes and casual movers can choose from 50 built-in fitness modes to log various physical activities. The hardware supports seamless pairing with both Android and iOS operating systems, ensuring broad accessibility for mobile users regardless of their preferred smartphone ecosystem.
Global Pricing and Regional Availability
Initial commercial availability remains limited, with the fitness tracker currently found for sale officially in Poland. Retailers there list the device at PLN 139, which converts to roughly $38 USD, available in three distinct colorways.
Broader European expansion is already on the horizon. Industry leaks originating from Quandt and WinFuture indicate that the Smart Band 11 Active will soon roll out across the wider Eurozone carrying an expected retail price tag of approximately €40, translating to about $45 USD.
