If you’ve ever felt drained after a full night’s sleep or wondered why you’re
always tired by 3 p.m.,
you’re not alone. And sometimes, the answer isn’t “more coffee” — it’s smarter
tracking.
Enter the Xiaomi Watch S4 (41mm), released in 2025.
It’s not just another smartwatch. Think of it as a lightweight, daily health
companion that quietly gathers insights about your body — right from your
wrist.
Here’s a deep dive into the specs, real-life experience, strengths, and a few things to keep in mind before buying.
First Impression? Incredibly Lightweight
The very first thing you notice is how light it is — just
about 32g.
It doesn’t dig into your wrist or leave marks after long use. That’s a win.
| Specification | Details |
|---|---|
| Display | 1.32-inch AMOLED, 466×466 resolution |
| Brightness | Up to 1500 nits (great for outdoor use) |
| Weight | Approx. 32g |
| Case Size | 41mm |
Perfect for slim wrists, especially for women or those who prefer compact
designs.
The minimalist finish pairs well with both formal wear and gym clothes.
Battery That Actually Lasts
Let’s be honest — no one enjoys charging their watch every night.
Thankfully, this model has your back.
- Up to 8 days with light usage
- Around 4 days with typical use
In my experience, even with continuous heart rate and sleep tracking turned
on,
I got around 3.5 to 5 days comfortably.
It’s the kind of watch you don’t need to babysit.
All the Health Tracking You Really Need
While it doesn’t claim to replace medical devices,
for daily wellness monitoring, this smartwatch checks all the right boxes.
- 24/7 heart rate monitoring
- SpO₂ (blood oxygen) measurement
- Stress level detection
- Sleep analysis (light/deep sleep breakdown)
- Activity tracking: steps, calories, sedentary alerts
For me, it revealed a clear pattern in my energy dips.
Turns out, my deep sleep duration was consistently low — something I never
realized until I tracked it.
After adjusting my bedtime routine, my focus during the day noticeably
improved.
Seamless Connectivity, NFC Included
With Bluetooth 5.3, pairing was fast and stable.
The built-in NFC enables basic payment and transportation
card functions.
While it's not a full Apple Pay or Samsung Pay replacement yet,
it supports basic tap-to-pay or transit card features in supported regions.
Notifications (calls, messages, calendar) synced smoothly as well.
What Users Are Saying: "Helped Me Understand My Fatigue"
One user review summed it up perfectly:
“I wore it all day — from commute to bedtime — and it helped me identify a
hidden fatigue pattern.”
That’s the real value here:
Not just numbers, but insight into your health habits, without
needing to interpret complex charts.
Downsides? A Few to Consider
No product is perfect, and here’s what stood out:
| Weakness | Notes |
|---|---|
| Not a medical-grade tool | Use it for trends, not diagnosis |
| Limited service network | Xiaomi’s support and repair options may be less robust in some countries |
| UI language quirks | Some English or odd translations in app menus |
Still, for its price point and functionality,
it easily ranks among the most value-packed smartwatches out
there.
Best For…
- First-time smartwatch users
