Xiaomi Watch S4 Sport: Diving Controversy Truth Revealed

Xiaomi Watch S4 Sport Diving Controversy: Separating Fact from Fiction

The Xiaomi Watch S4 Sport has been making waves in the world of smartwatches, particularly for its advertised diving capabilities. However, a recent controversy questioning its underwater reliability has surfaced, threatening to overshadow its features as a smartwatch for diving. But is there any truth to these claims? This article dives deep into the issue, separating fact from fiction, and providing an official response from Xiaomi, ensuring you have the most accurate information before making your next purchase. We’ll explore the differences between models, address the accusations, and see why this waterproof smartwatch remains a top choice for aquatic sports enthusiasts in 2025.

The Allegations: Is the Xiaomi Watch S4 Sport Actually Dive-Proof?

The controversy began with a viral video showcasing a customer service call where a user claimed their “diving watch” malfunctioned after being submerged. The representative allegedly stated the watch was “waterproof, but not recommended for underwater use.” This quickly sparked outrage online, with many questioning the validity of the Xiaomi Watch S4 Sport’s diving certifications. Was this a product defect, or a misunderstanding?

Xiaomi’s Firm Response: “Completely False and Manipulated”

On November 21, 2025, Xiaomi issued an official statement refuting these allegations. The company vehemently denied the claims, labeling them as “malicious disinformation” intended to damage their reputation and stating they will pursue legal action. The key point? The audio in the video allegedly pertained to the standard Xiaomi Watch S4, not the Xiaomi Watch S4 Sport. This intentional confusion has led to the controversy. Xiaomi emphasizes that it welcomes fact-based scrutiny but will actively combat the spread of falsehoods. The reliability of Xiaomi products is of utmost importance to the company, as it tries to lead the pack in tech news.

Real-World Reviews: What Divers Are Saying in 2025

Beyond the controversy, real-world user reviews paint a largely positive picture. A diver from Shanghai shared their experience on Reddit: “Used it for diving and swimming; the price of 1,700 RMB is incredible, although the voice alerts are in Chinese.” A YouTube review also highlights its performance in waterproof diving tests, confirming it can withstand depths of up to 40 meters without issues.

Forums like GSMArena praise its battery life (up to 15 days), bright OLED display, and training algorithms co-developed with Suunto – ideal for smart sporting watches. Of course, there are mentions of limitations, such as avoiding saunas or high-pressure water jets (common for all EN13319-certified watches), but nothing that negates its use in recreational diving. Xiaomi is working hard on the HyperOS for future users.

In the specific case of the user in the viral video, Xiaomi replaced the front module and waterproof seals under warranty, restoring the diving functionality. The company acknowledged that its customer service language was “imprecise” in suggesting “cautious observation” post-repair, leading to confusion. They apologized directly to the user (who accepted) and launched an internal audit to improve support.

Why the Xiaomi Watch S4 Sport Shines in 2025

Launched in July 2024, the Xiaomi Watch S4 Sport is positioned as Xiaomi’s most advanced smartwatch for extreme sports. Its titanium casing, eSIM for standalone calls, and custom Xuanjie T1 chip offer up to 15 days of battery life – a dream for explorers. It also works great as a companion to your smartphone.

In 2025, with the rise of diving wearables, this model competes strongly. It’s more affordable than the Apple Watch Ultra but just as robust. Global reviews praise its accuracy in tracking dives, surpassing the Huawei Watch GT 5 in depth. If you search for “Xiaomi diving watches 2025,” this is a top hit: supporting apnea, tank diving, and gauge modes, all for under 300 USD. Consider reading more about the Redmi K90.
