The Xiaomi Watch S1 Pro is best for someone who wants a traditional-looking, large-screen smartwatch for notifications, workouts and everyday health tracking—not a cellular or app-rich replacement for a phone. Its stainless-steel case, sapphire glass and bright circular AMOLED screen are compelling hardware; the compromises are a limited software ecosystem, phone dependence and review-reported inconsistencies in GPS and workout tracking. Battery life can be strong, but Xiaomi’s headline figures are laboratory claims tied to specific settings.
What the Xiaomi Watch S1 Pro offers
Xiaomi lists the S1 Pro as model M2134W1. The 46 mm stainless-steel case measures 46 × 46 × 11.28 mm, excluding the strap and protrusions. Its 1.47-inch AMOLED display has a 480 × 480 resolution and sapphire glass; Xiaomi also lists sapphire over the heart-rate window. The package includes a wireless charging base and cable. Xiaomi’s specifications also list 5ATM water resistance, a 500 mAh lithium-polymer battery, wireless charging, and sensors for heart rate and blood oxygen, motion, orientation, barometric pressure, ambient light, capacitive input and temperature.
The round face, physical controls and metal construction give it the look of a conventional watch rather than a small phone on the wrist. Anyron Copeman, reviewing for Tech Advisor, wrote that “The Watch S1 Pro strikes a nice balance between durability and looks.” That is a reviewer’s design impression, not a durability test result. Tech Advisor’s review also praised the screen and described navigation as responsive.
How good is the screen and everyday smartwatch experience?
The display is one of the watch’s strongest features: Xiaomi specifies a high-resolution 1.47-inch circular AMOLED panel, and Tech Advisor’s reviewer found it impressive. A large round screen suits watch faces and makes notifications and menus easier to read than on a compact fitness band. The trade-off is size: the 46 mm case will feel substantial, particularly on smaller wrists.

For everyday use, expect the basics—notifications, watch faces, health metrics and exercise features—rather than the flexibility of a full smartwatch platform. Wareable and Tech Advisor both report that the S1 Pro does not support third-party apps. Wareable also describes its Alexa experience as restricted. If you rely on installing new services or expanding watch functions with apps, this is a meaningful limitation, not a minor missing extra. Wareable’s review and Tech Advisor’s review provide those assessments.
How is the battery life of Xiaomi Watch S1 Pro?
Xiaomi advertises up to 14 days of typical use, 10 days of intensive use and 5 days with the always-on display enabled. These are Xiaomi laboratory claims, not guaranteed owner results. Its typical-use mode assumes limited calling and music, 200 screen checks and 100 notifications a day, eight NFC payments a day and three 30-minute outdoor GPS workouts per week; it disables blood-oxygen, stress and high-precision sleep monitoring. The intensive-use mode enables more tracking and increases notifications and workouts. Xiaomi says actual endurance varies with settings, habits, use and environment. The UK product page gives the test conditions.

Real-world reports are lower under demanding settings. Wareable reported about eight days in its review while using the always-on display and tracking features and doing frequent outdoor exercise; it expected shorter endurance with frequent GPS workouts. That result describes Wareable’s test, not a universal estimate for owners. Always-on display, GPS sessions and health tracking are the settings most likely to make the advertised maximum a poor predictor of your own use.
Workout, heart-rate and GPS tracking
Xiaomi lists BeiDou, GPS, GLONASS, Galileo and QZSS positioning, as well as heart-rate and blood-oxygen measurement. A list of supported systems does not by itself establish tracking accuracy. Wareable found heart-rate readings reasonably close to comparison devices in many of its logged workouts, but reported one outdoor run in which the reading became stuck and produced a substantially higher average than its Garmin and Whoop comparisons. It also reported GPS route-placement errors and less detailed sleep-stage output. These are observations from Wareable’s review, not independent laboratory validation.

- Two year warranty against factory defects.
Tech Advisor reported that an accidental button press ended a tennis workout in its review. That is a practical consideration for activities with wrist movement or contact: check whether the controls are protected or can be locked for your intended workout. Taken together, the reviews suggest the S1 Pro can cover ordinary activity tracking, but buyers who need dependable GPS routes, detailed sleep analysis or consistently reliable workout records should weigh those review findings carefully.
Does Xiaomi Watch S1 Pro support iOS/Android system?
Yes. Xiaomi says the watch pairs with Android and iOS through the Mi Fitness app; its Singapore support FAQ warns that the older Mi Wear app does not bind the S1 Pro. The official minimum operating-system requirements are not identical across regional pages: Xiaomi’s general specifications list Android 6.0 or iOS 13.0 and later, while its Malaysia listing gives a different iOS minimum. Check the support page for your country and your phone’s software version before buying. Xiaomi’s specifications and Singapore’s FAQ explain pairing and compatibility.

- Stunning images, smooth touch: Immerse yourself in brilliant clarity with the large 1.72-inch AMOLED display.Vacuum filling sealing technology enables symmetrical 2.0mm ultra-thin bezels, expanding screen-to-body ratio from 66% to 73%. Enjoy incredibly smooth and seamless interaction with crisp, color-accurate images, right on your wrist.
There is no cellular model, according to Tech Advisor. The watch therefore depends on its paired phone for many functions, and it is not a standalone option for calls and connected services when you leave your phone behind. Xiaomi also qualifies certain integrations to selected phone models or supported software versions, so features such as quick pairing or synchronization should not be assumed to work identically with every Android phone or iPhone.
NFC payments, water resistance and charging
Payments and regional features
Xiaomi qualifies NFC payment availability by region and Mastercard terminal support; the presence of NFC should not be read as a promise that payments will work in every country or with every bank. Check the local product and support pages for your market before treating payments as a deciding feature. Xiaomi’s UK product page describes the regional qualification.

Swimming and water exposure
Xiaomi rates the watch 5ATM and says it can be worn for swimming on its UK page, which also includes water-use qualifications. A rating is not permission for every water sport, depth, temperature or condition; follow the water-resistance guidance applicable to your region. Xiaomi’s UK page is the relevant reference.
Charging and replacement straps
Use the standard S1 Pro charging base rather than a generic wireless charging pad. Xiaomi warns that a generic pad can cause abnormal charging, heat and battery expansion, and recommends the standard base with an appropriate 5V/2A-or-higher adapter or a qualifying adapter. The charging base and cable are included according to Xiaomi’s specifications, so a replacement base is mainly relevant if the original is lost or damaged. Xiaomi says the original leather and fluororubber straps support quick release; confirm exact S1 Pro compatibility on any replacement strap listing. Xiaomi’s Singapore FAQ covers charging, while its strap FAQ describes quick release.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What did independent reviews and test listings establish?
The product was reviewed by Wareable and Tech Advisor around 2023, so their findings describe those review contexts rather than a 2026 firmware retest. Stiftung Warentest lists a test program titled “Smartwatches und Fitnesstracker 11/2022,” published online on 23 November 2023. Its listing says the model is no longer commercially available and gives a last average online price of €232 as of 12 January 2026; that is a dated German-market figure, not a current global price. The detailed battery result is gated on the listing, so no battery score can be stated from it. Stiftung Warentest’s product listing provides those details.
Quick Recap
Who should buy the Xiaomi Watch S1 Pro?
- Consider it if you want a large, circular AMOLED display, a stainless-steel watch design, sapphire glass, basic health and fitness functions, and are content to use the Mi Fitness app with your phone.
- Look elsewhere if you need third-party apps, cellular independence, broad compatibility for region-specific services, or workout and GPS records you can rely on without checking against the review-reported limitations.
- Before buying, confirm local availability and price, your phone’s compatibility, whether NFC payments work in your country, and which features your particular phone supports. The available evidence does not establish a current universal price or inventory picture.
