Xiaomi Watch S4 41mm Global Launch Expected Alongside 15T Series

Xiaomi is reportedly preparing a more compact version of its latest smartwatch for the global market. According to a leak from Roland Quandt, the Watch S4 41mm is expected to debut on September 24, alongside the Xiaomi 15T and 15T Pro smartphones.
The Watch S4 series made its first appearance at MWC 2025 with the larger 47mm model. Xiaomi later introduced the 41mm edition in China, catering to users who found the original design bulky. While the Chinese variant recently received an upgrade with the Xring T1 chipset, it remains unclear if this update will extend to international models.
The global 41mm model is expected to include a 1.32-inch AMOLED display, a 320mAh battery, and support for Xiaomi’s latest software platform, HyperOS 3. Health and fitness tracking remains a core feature, offering heart rate monitoring, SpO2 measurement, sleep tracking, and multiple workout modes. Additional features such as notifications, music controls, and interchangeable straps enhance usability and personalization.
Pricing is tipped at around €159.99 (approximately $188) in the Eurozone, positioning it competitively against Samsung’s Galaxy Watch FE. The smartwatch retains a premium feel with a stainless steel case, though Xiaomi has yet to confirm which finishes or strap options will be offered internationally.
If accurate, the smaller Watch S4 41mm will broaden Xiaomi’s smartwatch lineup, appealing to users seeking a lighter, more discreet wearable without compromising on essential features. With the September 24 launch event approaching, fans will soon discover how this new addition fits into Xiaomi’s growing wearable ecosystem.
