The Xiaomi Watch S4 (41mm) packs flagship-looking hardware into a compact, light package with a bright AMOLED and strong battery claims — all at a price that undercuts many premium smartwatches. It’s ideal if you want great display quality, thorough health tracking, and long battery life in a smaller size, but it’s not the top choice if you rely on rich third-party apps or need Wear OS-style app ecosystems
Xiaomi Watch S4 Design & fit
The 41mm Watch S4 is clearly aimed at users who prefer a compact watch. Xiaomi lists the case at about 41.2 × 41.2 × 9.5mm and ~32 g without the strap, thin and light enough for everyday wear and sleep tracking without feeling bulky.
The frame uses stainless steel and the watch ships with silicone (fluororubber) straps in several colors. If you’ve had larger smartwatches, this one will feel noticeably less obtrusive.
Why that matters: many people who avoid smartwatches do so because of size & weight. Xiaomi’s 41mm keeps the “smartwatch advantages” while minimizing wrist presence.
Xiaomi Watch S4 Display
The Xiaomi Watch S4 comes with a 1.43-inch AMOLED display that looks sharp and vibrant on the wrist.
It seems so big that you can see the notification without shrinking your eyes or can see time, yet it is so compact that it does not look heavy.
The best thing is that it is also very good for out door use. Even in the straight sunlight, the screen remains clean due to its high brightness, so you do not have to put a shade with your hand to read it.
Colors look rich and lively, from which watch face emerges. Whether you like simple designs or more stylish, Xiaomi offers many customized face that take full advantage of the AMOLED panel.
Scrolling in the menu or swipe between widgets also seems easy, which provides a good experience.
In short, the display of Xiaomi Watch S4 is designed to look good in any situation – inside the house, outside, day or night – and also everything clean and comfortable for the eyes. This is not only functional, but it makes the watch premium and pleasant to use daily.

Xiaomi Watch S4 Health & fitness features
Xiaomi Watch S4 has an excellent set of health and fitness equipment that goes far beyond counting steps. It keeps an eye on your heart rate, blood oxygen levels, stress and even sleep round the clock. From the same tap, you can run a quick health scan that gives you a snapshot of your current situation.
For workouts, it supports more than 150 sports mode, which includes everything from running and cycling to swimming and hiking. Thanks to the dual-band GPS, it also tracks the outskirts in a very accurate way, which is very good if you like running out or cycling.
Sleep tracking is another strong aspect. This clock not only records how long you sleep – it also analyzes your breathing habits and also highlights the possible sleep problems. In addition, it also has underlying breathing exercises that help you relax when stress increases.
Overall, the Watch S4 offers you a good set of equipment to focus your health and fitness, whether you are generally active or more serious about training.
Xiaomi Watch S4 Battery Life & Features
The Watch S4 runs Xiaomi’s wearable software (HyperOS for wearables in this family), which focuses on smooth system UI, health dashboards, and Xiaomi’s companion app for configuration and data syncing.
It’s straightforward and energy-efficient, but it doesn’t deliver a large app ecosystem like Wear OS (Google) or watchOS (Apple). If third-party watch apps are essential to you, this is a trade-off: excellent native features, fewer app-store extras.

Xiaomi Watch S4: Price breakdown
Official China launch price:
Xiaomi announced pricing starting at CNY 999 for certain variants at launch (roughly around the ₹12k ballpark at typical conversions), which positions the S4 strongly against rivals.
Global / Europe:
Xiaomi’s global pages and early rollouts show euro pricing in different markets, with regional variations depending on strap.
India:
listings and price expectations vary. Price-tracking sites list an expected India price around ₹11,999, while early retailer listings seen online show higher seller prices in some cases (so actual street price may vary until official India retail availability stabilizes). If you’re budgeting, expect the S4 to live in the mid-budget smartwatch bracket rather than premium flagship prices.
Here’s what we think
The Xiaomi Watch S4 (41mm) is one of those rare devices that balances style, display quality, and battery life without commanding a premium price.
For everyday users and fitness-minded people who don’t need a sprawling app library, it’s a highly sensible pick especially if Xiaomi maintains competitive regional pricing.
If you value a slim, light watch with a vivid screen and long endurance, the S4 is a standout in its segment.
