Therefore, the update notification may take a little longer to appear in Spain and the rest of Europe.
What does Xiaomi intend to achieve with HyperOS 3 in its wearables?
Xiaomi itself acknowledges that the goal goes beyond simply changing icons or colors. With this version, the brand wants to unify the aesthetics and behavior of the system across all its devicesso that the user notices a similar experience whether they use a mobile phone, a tablet, a Smart Band or a watch.
According to the division responsible for these products, the idea is for wearables to evolve from a simple accessory for checking the time or counting steps to becoming a a more coherent extension of the HyperOS ecosystemThe company had already tested some of these improvements in November, when the Xiaomi Smart Band 10 and the Xiaomi AI Glasses They got ahead and launched the new version of the system before anyone else.
The arrival of HyperOS 3 to activity trackers and smartwatches is supported on several fronts: a clearer and faster interface, navigation better designed for small screens and more stable performance in health and sports monitoring tasks.

Xiaomi watch and fitness tracker models that will receive HyperOS 3
The list of wearables being updated this month is relatively short, but it includes several of Xiaomi's best-selling models in Spain and Europe. The company itself has released an official list of devices. that are in the first wave of the update.
On one hand, there are the benchmark activity trackers: la Xiaomi smart band 9 and the Smart Band 9 ProThese are two of the most popular models on the market and, until now, were still running on the previous version of the operating system. The Smart Band 10, however, already made the jump to HyperOS 3 in November, so the transition is now complete for the immediately preceding models.
On the other hand, HyperOS 3 is also coming to smartwatches with the brand's own operating system, specifically to the entire Xiaomi Watch S4 seriesIt is in these watches where some of the most striking new features can be seen, especially everything related to payments and advanced connectivity.
The list is completed with the Redmi Watch 5 seriesAnother family of devices is aimed at those looking for an affordable watch with smartwatch features. These models share many of the software updates with the Smart Band 9 and the Watch S4, although there are some differences depending on the hardware and sensors.
It's worth remembering that Xiaomi has already confirmed that Some previous generations of their wristbands will also receive HyperOS 3 Throughout the month, although it hasn't specified exactly which ones. Everything points to the Smart Band 8 being included at the very least, first in China and later in international markets.
Update schedule: December as a key month
Regarding dates, Xiaomi has opted for a cautious approach. The company states that The update will arrive “sometime during the month of December” to the Smart Band 9, Smart Band 9 Pro, Redmi Watch 5 and Watch S4, without specifying an exact day.
This means that users can periodically check the section of System update in the watch or bracelet settingsThe corresponding notification should appear there as soon as the firmware is available. Distribution is being done in stages, in batches and by region, to avoid overloading the servers and to allow for a response to any potential issues.
In China, the rollout is usually a few days ahead, so it's possible that the European users, including the Spanish marketUsers may have to wait a little longer to see HyperOS 3 on their wearables. However, various leaks and official announcements agree that the process should be completed before the end of the month.
In the case of the previous generations of Smart Band that Xiaomi mentions without specifying, the situation is similar: the company speaks of December as a general windowHowever, it allows each region to adjust the schedule based on certifications, translations, and stability testing.
HyperOS 3 changes you'll notice on your wrist
The part that most interests the end user is, logically, what changes once you install HyperOS 3. Here Xiaomi places special emphasis on the update It's not limited to a visual faceliftbut it introduces a series of improvements that directly affect everyday use.
One of the points that is being emphasized the most is the overall fluidity of the systemInitial internal testing and hands-on experience with the Smart Band 10 indicate faster screen transitions, better-organized menus, and smoother animations. The goal is for interaction to be seamless, without any lag when scrolling through lists, opening the daily summary, or switching widgets.
Work has also been done on the rhythm, cadence, and activity detection algorithmsOne of the most frequent complaints in previous generations, especially during interval training or sessions with sudden changes in intensity, is the inconsistency of the movement. HyperOS 3 introduces adjustments to make sports metrics more consistent and to help the system better identify when an exercise is genuine and when it's an erratic movement.
In terms of aesthetics, the update includes Updated icons, clearer navigation, and a more consistent design between screens. Although Xiaomi hasn't detailed every visual change down to the millimeter, it does mention an interface that's closer to what's seen on phones and tablets with HyperOS 3, both in the layout of elements and in the color palette.
Furthermore, the possibility of hide pre-installed apps you never useThis feature, highly requested by the community, allows you to clean up the app carousel and only see what you actually need to use on a daily basis, avoiding having to navigate through menus full of irrelevant icons.
Specific new features in sports, GPS and notifications
Beyond improved fluidity, HyperOS 3 also includes changes designed for those who use their watch or fitness tracker to monitor their athletic activity. One of the standout features is... improved GPS accuracy, especially relevant in models with integrated positioning such as the Smart Band 9 Pro or the Redmi Watch 5.
These devices include an option to “satellite ephemeris” or manual data preloadingThis allows the wearable to calculate your position more quickly when starting an outdoor workout. In practice, this should mean less time waiting for the GPS to stabilize before you start running or walking.
The following have also been reviewed step frequency algorithms and anomalous exercise detectionThe intention is to make the pace, distance, and cadence graphs more reliable. These adjustments are especially noticeable in interval training or workouts with rapid speed variations, where some previous models could display unrealistic spikes.
In the notifications section, HyperOS 3 introduces a mode of “focus” or focus in models like the Smart Band 9 Prowhich activates automatically when you raise your wrist. This behavior is designed to display only essential information and reduce distractions, instead of flooding the screen with continuous notifications.
The Redmi Watch 5 series also receives a specific upgrade for avoid accidental touches on the screenThis can happen during daily use, especially during workouts or while wearing warm clothing. The aim is to reduce unintentional screen changes, unwanted pauses in activity, or accidental app openings.
Wrist payments and limited NFC functions
Another focus of HyperOS 3 on Xiaomi watches is on payments and short-range connectivity. The company has confirmed that the Xiaomi Watch S4 range finally incorporates “tap-to-pay” payments, one of the functions most requested by the community for a long time.
With this new feature, Watch S4 users will be able to pay by bringing the watch close to a compatible terminalProvided the payment system is available in your region and your bank offers support, this is a significant step forward for those who want to leave their phone at home when going for a run, running quick errands, or simply getting around town with only the essentials.
It's not the only NFC-based function. Both the smart band 9 like the family redmi watch 5 They add the possibility of using it as a car key in certain models of the brand, a feature that for now is limited to the Chinese marketIn Europe, this option has less traction at the moment, but it shows where Xiaomi wants to go in terms of integration with its range of vehicles.
In some markets, the incorporation of a specific car key using NFC (YU7) In certain bracelets, this reinforces the brand's commitment to making the wearable an integral part of the home and mobile ecosystem. It remains to be seen which of these features will ultimately reach Spain and under what conditions.
For now, the most tangible change for European users will continue to be the interface improvementThe increased fluidity, new customization options, and sports optimizations are welcome, while some advanced NFC features may take longer to become established outside of China.
Impact in Spain and Europe: what users can expect
In the European context, and especially in Spain, Xiaomi has been consolidating its catalog of wearables for some time as a an affordable alternative to other brands' offeringsThe arrival of HyperOS 3 fits with that strategy, by adding value to products that many users already have on their wrists.
It makes sense for the rollout in Europe to follow the same path as what Xiaomi has done with its mobile phones: gradual update via OTA from device settingsStarting with the global variants and later expanding to more regions and versions. In any case, the confirmed models are not expected to be delayed beyond the beginning of 2026.
For those who already use a Smart Band 9, 9 Pro, a Redmi Watch 5 or a Watch S4, the main advice is to check from time to time if there are new software versions available and keep the Xiaomi app updated on your phone. The HyperOS 3 update will be downloaded and installed directly from your device, without any complicated processes.
Although some features like the NFC car key will remain exclusive to China for now, the other improvements—especially in performance, interface, and sports modes—should arrive without significant cuts to the models sold in Europe. This includes the GPS optimizations, adjustments to sports algorithms, the ability to hide pre-installed apps, and improvements to notifications.
In practice, this means that recent Xiaomi wearables get a second life at no extra cost. The brand is strengthening its ecosystem with a software update that unifies the experience across mobile phones, tablets, and wrist devices.with a clear focus on real performance and usability, beyond marketing.
With HyperOS 3, the Smart Band 9, 9 Pro, Redmi Watch 5 and Watch S4 are ready for a longer usage cycle with a more polished system, better integration with the rest of the company's gadgets and a more precise sports focus, so that those who have already opted for these devices will see how their watch or bracelet is updated internally without having to pay extra.
