Xiaomi has launched the Smart Band 11 in China with a brighter AMOLED display, a thinner body and a claimed battery life of up to 21 days. NokiaMob listed the product on September 5, while Android Authority separately reported the launch details and China pricing. The immediate story is a local release, not a confirmed global rollout.

The standard model starts at 289 yuan, about $43 before taxes, shipping and currency changes. Android Authority reported a 339-yuan price for the NFC version and 399 yuan for the ceramic model. NokiaMob also listed an all-metal edition at 399 yuan. Those are China prices. They should not be treated as the final price for India, Bangladesh, the United States or another market.

The Smart Band 11 uses a 1.72-inch AMOLED panel with a claimed peak brightness of 2,000 nits. Android Authority said the display has 2mm bezels. A brighter panel can make a small tracker easier to read outside, where reflections often matter more than indoor brightness. The claim comes from Xiaomi’s launch material as reported by the two outlets, so independent testing will be needed to check outdoor visibility.

The band is also slimmer than its predecessor. NokiaMob reported a thickness of 9.99mm and a weight of 15.58 grams for the standard body without the strap. The lighter figure does not include the band, and a metal or ceramic version may feel different on the wrist. Buyers comparing models should check how each manufacturer measures weight and thickness.

Health and fitness tracking remains the main reason to buy the device. The reported features include heart-rate, blood-oxygen and stress monitoring, women’s health tools and sleep tracking. Xiaomi has added heart-rate variability, or HRV, monitoring for sleep and AI-based sleep insights. These functions can help users review personal patterns, but they are wellness features. They are not a diagnosis or a replacement for clinical equipment.

The Smart Band 11 supports more than 150 sports modes, according to the launch coverage. It also keeps a 5ATM water-resistance rating. Those specifications make it suitable for routine workouts and swimming-related use, although water resistance is not a promise that every activity or condition is safe for the band.

Software is another change. The tracker runs Xiaomi HyperOS 4 and works with Android and iOS phones. NFC is included on selected versions, with support for payments or access cards depending on the market and service. A China model may not offer the same payment functions after a buyer imports it into another country.

Xiaomi claims up to 21 days of battery life on one charge. Actual endurance will depend on brightness, notification frequency, sleep tracking, workout recording, sensor use and the phone connection. The highest-brightness setting and continuous measurements can reduce the time between charges.

Global availability is still open. The reports say Xiaomi has not announced an international launch date or confirmed which China features will travel to other regions. For buyers outside China, the useful update is that the Smart Band 11 is now a real China product with published local prices and specifications. A global price, warranty and supported payment services still require a separate Xiaomi announcement.
