Modern wearables are no longer just pedometers, becoming full-fledged multimedia centers on the wrist, and the Xiaomi Watch S1 Active is a bright representative of this class of devices. Users often wonder how to maximize the full potential of this model, from initial activation to fine-tuning health monitoring functions. In this article, we will discuss all aspects of the operation of a smartwatch that will help you avoid common mistakes.
Many owners buy a device without reading the instructions and subsequently face problems synchronizing or calibrating sensors incorrectly. Proper settings from the first turn on are the foundation for the stable operation of all systems, including the use of the system. GPS-We're going to look at not only the basics, but also the hidden capabilities of the operating system. MIUI For Watches that often go unnoticed.
Particular attention should be paid to compatibility, as the process of pairing with Android and iOS has its own unique features that affect functionality. For example, iPhone owners may face restrictions when responding to messages, while Android users get increased control over notifications. Understanding these nuances will allow you to choose the best scenario for using the gadget in conjunction with your smartphone.
Primary configuration and pairing with the application
The activation process begins long before you hit the power button, and requires pre-prepared software on your smartphone. The first step is to download the official Mi Fitness app (formerly known as Zepp Life in some regions, but the first one is relevant for this model) from Google Play or the App Store. Installing third-party analogues can lead to incorrect notifications or inability to update the firmware, which is a critical point for system stability.
Once you install the app, launch it and log in to your Mi Account, which is essential to sync health and activity data between devices. Turn on Bluetooth on your phone, but don't try to find the watch through the smartphone's standard Bluetooth settings menu - this is a common bug that leads to double pairing and conflicts. Instead, open the Devices tab in the app and click the add a new gadget, after which the system will automatically detect the Xiaomi Watch S1 Active.
⚠️ Attention: During the initial pairing process, do not turn off the smartphone screen and keep the watch no more than 30cm from the phone. Interrupting encryption key exchange can cause the watch to become invisible for re-search.
An important step is to provide all the permissions requested, especially for background and geolocation access. Without permission to permanently access the location (for Android), Connected GPS will not work properly, and maps in running apps will not be able to plot a route. It is critical for iOS users to allow access to notifications, otherwise you will not be able to see incoming messages from messengers on the watch screen.

Interface, navigation and customization of dials
The clock’s operating system is built on the logic of ring navigation and listing, which requires some adjustment after using other WearOS devices. Control is done by rotating a physical crown button that allows you to scroll through lists of applications, and a touch screen that responds to swipes. The top swipe opens the quick settings panel where you can activate Do Not Disturb mode, turn on the flashlight or change the brightness, and the bottom one shows the history of notifications that can be cleared one or all at once.
One of the most popular features is the ability to change dials, which number in the thousands in the online store. You can choose a static image, animated background or a complex functional dial with a display of heart rate, steps and weather in real time. To set a new style, you just need to pinch your finger on the screen in watch mode, wait for vibration and selection, and then scroll the list or go to the dial store through the app.
- 🎨 Online Store: Access to thousands of free and paid designs with preview options 3D-clockwork.
- 📸 Photo dials: The ability to install any photo from the smartphone gallery, including portraits or landscapes, with automatic interface adaptation.
- ⚙️ Complex dials: Customize the displayed data (pulse, steps, calories) directly on the front panel for quick access.
Customizing the display information on the home screen also includes selecting the order of widgets that are available when swiping left or right of the dial. You can move activity, weather, cardio and alarm widgets, leaving only those you use daily to save navigation time. This makes the Xiaomi Watch S1 Active interface a flexible tool that adapts to the needs of a particular user, whether an athlete or an office worker.
The secret to a quick change of dial
Health functions and sports regimes
The device’s primary function is to monitor physical activity, which is supported by more than 117 sports modes, including running, swimming, cycling and yoga. To start a workout, you can use a voice command or select the desired sport through the Sport menu on the clock, after which the countdown and activation will begin. GPS-The positioning accuracy of this model is significantly higher than that of previous generations, thanks to the support of two navigation systems, which is critical for recording tracks in the forest or among high-rise buildings.
The health monitoring system works automatically to track heart rate, blood oxygen (SpO2) and sleep quality throughout the day. Stress data and breathing exercises are available to analyze the current state of the body, helping the user pause and regain strength. It is important to understand that sensors work most accurately when the strap fits tightly to the wrist, but you should not tighten it excessively so as not to disturb blood circulation.
For swimmers, the 5 ATM sealed body is important, allowing swimming and showering, but eliminating scuba diving or hot water (sauna, hot springs). After water procedures, it is recommended to rinse the watch with fresh water, especially if they have come into contact with chlorinated pool water or salt sea water, to avoid corrosion of the speakers and charging contacts.
| Parameter | Description | Recommendation |
|---|---|---|
| Pulse rate | Continuous monitoring | Include for accurate calorie calculation |
| GPS | Built-in module | Use it in open areas |
| Waterproofness | 5 ATM (50 metres) | Not to use in the sauna |
| SpO2 sensor | Oxygen measurement | Checking while sleeping or resting |
💡
For maximum accuracy of pulse measurement during exercise, slightly shift the clock above the wrist bone so that the sensor does not overlap with the tendons when bending the arm.
Notifications, calls and interaction with the smartphone
Communication features not only allow you to see incoming calls, but also respond to them directly from the clock, because the model is equipped with a built-in speaker and microphone. The quality of communication depends on the distance to the phone and the level of interference, but in most cases, the voice of the interlocutor is clearly heard even in moderate urban noise. When a message comes from the messenger (WhatsApp, Telegram, Viber), text is displayed on the screen, which allows you to quickly assess the importance of the notification without removing the phone from your pocket.
Notification management is flexible through the Mi Fitness app, where you can select specific applications whose alerts will be duplicated on the wrist. The smart response system (depending on the region and version of the software) allows you to send pre-prepared phrases or emojis in response to messages, although full keyboard input is not provided in this model, making the watch an ideal filter to ignore information noise and respond only to really important events.
It also allows you to control music playback on your smartphone by switching tracks and adjusting volume through the media player interface. If you use streaming services or a local library, this gives you complete control over the sound of the workout, but it is worth remembering that the watch does not have its own memory for storing music files and acts solely as a remote control.
Autonomy, charging and battery optimization
One of the strengths of the Xiaomi Watch S1 Active is its impressive autonomy, which, when used moderately, reaches 12 days, and in base mode - up to 24 days. Real life depends on many factors: on-going continuous monitoring of the pulse, frequency of GPS use, screen brightness and the number of notifications received. Active use of navigation during runs significantly reduces the life, but even in this mode, one charge is enough for several weeks of normal charging cycles.
Charging uses a magnetic cable with two contacts, which must be tightly attached to the back of the watch, providing reliable contact. The charge indicator on the screen and vibration signal will confirm the successful start of the process, and full charging takes about 2 hours. It is not recommended to use powerful chargers for smartphones (fast charging 30W and above), as the watch power controller may incorrectly recognize current, which will slow the process or overheat.
⚠️ Warning: Regularly wipe the contacts on the back of the watch and on the charging cable with dry cloth.Oxidation of contacts with sweat or moisture is the most common cause of charging problems and false readings of sensors.
To extend the battery life at night, you can activate Do Not Disturb mode or completely turn off the device if you do not use sleep monitoring functions. It is also worth noting that extremely low temperatures (below -10 ° C) can temporarily reduce battery capacity, which is the norm for lithium polymer batteries, and performance will recover when returned to heat.
💡
The optimal balance between functionality and autonomy is achieved by turning off the constant SpO2 measurement and reducing the screen brightness to 30-40%.
Updating the firmware and troubleshooting
Regular software updates are key to the stable operation of the device, as manufacturers often release patches that improve sensor accuracy and correct pairing errors. Updates are checked through the Mi Fitness app in the device settings section, where a notification will appear if there is a new version. The update process requires a battery charge of at least 30% and a stable connection to the Internet, and the watch itself must be located next to the phone.
In the event of problems such as an interface freeze, Bluetooth connection failure, or data display incorrectly, you may need to reset to factory settings, either through the settings menu on the watch itself (System → Reset) or forcefully by holding down the power button for a long time (over 15 seconds) after the reset, you will need to re-pair the phone and restore data from the cloud backup if it was created earlier.
If the watch has stopped responding to touches or buttons, try rebooting by holding the switch on button 10-15 seconds before the MI logo appears. In rare cases, when a software failure blocks the system boot, a connection to the service center may be required, but in 99% of cases a full reset through the recovery menu, which is logged in by a combination of buttons when the device is turned off.
