Xiaomi has announced two new additions to its wearables portfolio: the Watch S4 41mm, a more compact version of its flagship smartwatch, and the Smart Band 10, the latest upgrade in its long-running fitness band series. Both devices were unveiled in China and are expected to launch globally at a later date, although Xiaomi has not yet confirmed international availability.
The Watch S4 41mm features a 1.32-inch round AMOLED display with a 466 x 466 resolution, a 60Hz refresh rate, and 2,200 nits peak brightness, providing clear visibility even in bright conditions. Like its larger sibling, it carries a 5ATM water resistance rating and weighs only 32 grams, making it ideal for everyday wear.
Under the hood, it includes Xiaomi’s upgraded 4-LED + 4PD heart rate module for improved health tracking and integrates a modified version of the Xring T1 chip. This updated chip includes a more efficient modem, reportedly 35% more power-efficient than the one in the original Watch S4. Additional features include real-time heart rate tracking during swimming and a battery rated for up to 8 days of usage.
The Watch S4 41mm is available in Black and Mint Green with a TPU strap for $140. A brown leather strap version is priced at $167, while a Milanese strap variant is offered at $209.
The Smart Band 10 brings a notable display upgrade with a 1.72-inch AMOLED screen, a 60Hz refresh rate, and peak brightness of up to 1,500 nits. While the design remains largely unchanged from the Band 9, the bezels are thinner, and Xiaomi has introduced a ceramic edition, which will be available outside of China for the first time.
Xiaomi has enhanced the Band 10’s tracking capabilities by adding a 9-axis sensor and more advanced sleep monitoring with guided sleep improvement plans. The fitness tracker also features an improved vibration motor for better notifications and feedback.
It retains the same 233mAh battery as its predecessor, delivering up to 21 days of battery life under typical usage and 9 days with Always-On Display mode enabled. Pricing starts at $38 for the standard version and $52 for the ceramic edition.
