The Xiaomi Smart Band 11 NFC combines fitness tracking, wellness monitoring, and smart features in a lightweight and comfortable wristband for everyday wear. This version includes NFC connectivity , expanding the band's capabilities with contactless payments and other compatible cards, depending on service availability and participating banks in each country.

Screen and design

Its 1.72-inch AMOLED touchscreen offers a resolution of 212 x 520 pixels, a pixel density of 326 ppi, and a refresh rate of up to 60 Hz. The maximum brightness of up to 2000 nits , along with automatic adjustment, makes it easy to read information outdoors and under different lighting conditions.

The screen is covered by 2.5D Panda MN228 reinforced glass , with a declared surface hardness of at least 9H. The body is 9.99 mm thick—not including the sensor protrusion—and weighs approximately 16 g without the strap.

NFC and payments

NFC connectivity is enabled by default and allows you to add compatible bank cards using Xiaomi Pay. Once set up, certain transactions can be performed without keeping your phone connected.

It also supports emulation of some 13.56 MHz IC access cards. Encrypted, transport, access, or payment cards may have limitations depending on the system used. Actual compatibility depends on the country, bank, card, and services enabled by Xiaomi.

Health and rest

The bracelet allows you to monitor heart rate, blood oxygen saturation, stress, and sleep . It also offers sleep stage analysis, heart rate variability tracking during sleep, and measurements related to nighttime breathing.

The results can be viewed and synced using the Mi Fitness app. These features are intended for wellness and physical activity and are not a substitute for a medical device.

Sports activity

With over 150 sports modes , it allows you to track a wide variety of workouts and everyday activities. Its motion sensors help monitor steps, calories, exercise duration, and other activity-related metrics.

Battery and charging

The 233 mAh battery offers a theoretical battery life of up to 18 days with light use . Xiaomi estimates around 10 days with standard use, including monitoring and NFC operations, and approximately 6 days with the always-on display enabled.

Charging is done via a magnetic connector and takes approximately 90 minutes to fully charge the battery. A dedicated charging cable is included, but not a power adapter.

Connectivity and compatibility

The bracelet connects to the smartphone via Bluetooth 5.4 BLE and uses the Mi Fitness app to sync data, receive notifications, and manage your settings and cards.

It is compatible with devices using Android 8.0, iOS 14.0, or later versions . It does not have Wi-Fi, cellular connectivity, or a SIM card slot.

Water resistance

The 5 ATM rating, tested according to ISO 22810:2010, allows it to be used in swimming pools and during shallow water activities.

It is not suitable for scuba diving, jumping from platforms or diving boards, hot showers, saunas, hot springs, high-speed currents, or deep-water activities. Water resistance may decrease with time and wear.
