Xiaomi Watch S4 Smartwatch – AMOLED Display, NFC, Bluetooth Calling

Ever glance at your phone during a workout (or a meeting) and think, “There has to be a better way to handle notifications and quick calls?” A smartwatch can help—if it nails the basics: a readable screen, dependable battery, and the right features for day-to-day convenience.

A Bright Wrist Screen That’s Easy to Live With

The Xiaomi Watch S4 Global Version centers its experience around a 1.43-inch AMOLED display. AMOLED panels are known for punchy contrast and deep blacks, which typically makes watch faces and stats easier to read at a glance. And since this is a Mi smartwatch you’ll likely check dozens of times a day, the screen choice matters.

Here’s the thing — a 1.43-inch display hits a nice middle ground: large enough to read quickly, but still in familiar smartwatch territory rather than feeling like a mini phone on your wrist. And because the listing emphasizes the Global Version, it’s clearly positioned for buyers who want a broadly compatible Xiaomi smartwatch experience rather than something region-locked.

Calls, Taps, and the Convenience Trio: Bluetooth + NFC + GNSS

On the features front, the Xiaomi Watch S4 Global Version includes Bluetooth Calling, NFC, and GNSS. That combination is practical: Bluetooth calling is about handling quick conversations without pulling out your phone, NFC is for tap-style interactions, and GNSS supports location-based tracking for activities that rely on route data.

• Bluetooth Calling for taking calls from your wrist
• NFC for tap-enabled use cases
• GNSS for tracking location during outdoor activities

But ask yourself: do you want a smartwatch mainly for workouts, or mainly for everyday convenience like calls and quick interactions? The Xiaomi Watch S4 Mi smartwatch is clearly aiming to do both.

150+ Sports Modes: More Options Than You’ll Probably Use

If you like variety, the Xiaomi Watch S4 includes 150+ sports modes. Honestly, most people will settle into a handful of go-to activities, but having a wide set of modes can be useful if you train seasonally or switch between gym work, outdoor sessions, and niche workouts.

For what it’s worth, pairing lots of sports modes with GNSS makes this Xiaomi smartwatch feel more serious about tracking than “just a notifications watch.” It reads like a device built for people who want their Mi smartwatch to keep up when they change routines.

Battery Capacity That Sounds Promising (With One Small Unknown)

The Xiaomi Watch S4 Global Version is listed with a 486mAh battery capacity, which suggests it’s built with endurance in mind. Real-world battery life always depends on settings—especially Bluetooth calling and GNSS usage—but capacity is still a helpful anchor when you’re comparing smartwatches.

Quick note: the listing doesn’t spell out expected runtime in days, so if battery longevity is your top priority, it’s worth checking with the seller on typical usage scenarios.

Small Caveats Before You Hit “Buy”

Fair warning: if you plan to lean heavily on Bluetooth Calling and GNSS, those features can be power-hungry on any Mi smartwatch, so your mileage may vary depending on how you use them. And while “Global Version” is reassuring, you’ll still want to confirm it matches your preferred language/region setup before ordering.

If the idea of an AMOLED-screen Xiaomi Watch S4 with NFC, Bluetooth calling, GNSS, and a big list of sports modes fits your routine, this Xiaomi smartwatch is easy to justify on paper. And if it matches how you actually live—workouts, errands, quick calls—then it’s a solid pick to add to your cart.
