The Xiaomi Smart Band 11 is a budget fitness band with a 1.72-inch AMOLED display and 2 mm bezels. The body is 9.99 mm thick and weighs 15.58 g without the strap. It comes in standard, NFC, ceramic and all-metal versions, is rated 5ATM, and works with Android and iOS. It is also the first wearable announced with HyperOS 4. Compared with the Smart Band 10, the screen is brighter (2,000 nits peak), the body is thinner, and sleep tracking now includes HRV.
Xiaomi rates the battery at up to 21 days per charge. That is a manufacturer estimate, and the always-on display, NFC or continuous heart-rate and sleep monitoring will shorten it. Retailer spec sheets list the capacity as 233 mAh, but the figure comes from a third-party listing and Xiaomi hasn’t confirmed it.
In China the standard version launched at 299 yuan, with an opening sale price of 289 yuan (about $43). NFC is 339 yuan (about $50). The ceramic and metal editions are 399 yuan (about $60). Outside China it has shown up on Xiaomi’s Hong Kong and South Korea sites, with Europe expected next, and prices there are higher than the Smart Band 10’s. It fits people who want basic tracking and long battery life and have no need for a full smartwatch. Inside Xiaomi’s lineup it sits next to the Smart Band 10 and the Smart Band 10 Pro, which has a wider screen and a bigger battery. Elsewhere, the Samsung Galaxy Fit3 and the Amazfit Band 7 compete with it. The closest match is the Huawei Band 10, which lands in a similar price and battery range.
