This is currently Xiaomi’s top-of-the-line watch, even surpassing the highly acclaimed S1 Pro.
I also own an S3, but it simply can’t hold a candle to this one.

In terms of design, I’d say it has a rugged appeal that’s not for everyone. Girls, in particular, might find it less appealing. Both of my female family members prefer the sleeker look of the S3. But personally, I adore it—its build quality is nothing short of exceptional.

When it comes to eSIM functionality, the official word is that it supports both Telecom and Unicom. However, in reality, Telecom has temporarily halted its eSIM services, leaving Unicom as the only viable option at the moment.

Regarding app stores, I noticed that Xiaomi Health doesn’t offer one. All supported apps are pre-installed, so once you’re aware of this, the absence of an app store becomes a non-issue.

Many people weigh the decision between Xiaomi and Oppo X based on independent WeChat functionality. While I think it’s a neat feature, its practicality on a smartwatch is practically zero. Why? Do you really want to drain your battery life just for this convenience? Plus, the user experience isn’t all that great anyway.

By the way, the running algorithm still relies on Xiaomi’s proprietary system rather than Suunto. For activities like hiking or off-road adventures, however, it does leverage Suunto’s technology for enhanced performance.

    1. Great question! The S4 actually improves on the S3’s battery life, offering around 15 days in typical use (vs. 12 on the S3). Even with heavy GPS use, I’ve found it lasts noticeably longer. Personally, I think it’s one of the best upgrades in this model—thanks for bringing it up!

  8. I totally agree about the design being polarizing! My wife thought it looked too bulky when I showed her, but I love the rugged vibe—feels way more premium than my old S3. How’s the battery life holding up for you? That’s always my dealbreaker with smartwatches.

    1. Thanks for sharing your thoughts—glad you’re enjoying the rugged design! Battery life has been solid for me, lasting about 4-5 days with moderate use, which is a nice upgrade from the S3. Of course, heavy GPS or workout tracking will drain it faster, but it’s impressive for the feature set. Hope that helps!
