Modern wearables are no longer just an accessory for counting steps, becoming full-fledged smart gadgets that significantly expand the capabilities of the smartphone. Xiaomi Watch is a strong position in the market, offering users a balance between functionality, autonomy and affordable price. However, to get the most from the device, you need to properly configure it and understand the specifics of the operating system.
Owners often face issues of compatibility, data synchronization, and sensor interpretation. In this article, we will discuss how to choose the right model, install software, adjust notifications, and optimize battery consumption.
We will also discuss data security and the use of watches in conjunction with the smart home ecosystem, and understanding how Bluetooth protocol and activity tracking algorithms work will help you use your device more effectively in everyday life and sports.
Selecting the right model: S1, S3 or Active
Before buying or setting up, it is important to understand the differences between the series, as they are based on different software platforms. Flagship models of the S series often run on Wear OS or proprietary HyperOS, providing access to the app store and third-party widgets.
When choosing, you should pay attention to the presence of NFC-If you plan to use the watch for contactless payment (in supported regions) or smart home management, the body material is also a key factor: Aluminum and glass provide a premium look, but may be less resistant to impact in active sports compared to polymer counterparts.
Remember that you can't use your smartphone's operating system, but while most models work with both Android and iOS, the functionality on your iPhone can be limited, such as not being able to respond to messages or use voice input.
⚠️ Note: Models released for the Chinese market (CN Version may have limitations in working with global servers and the lack of Russian in the interface without additional manipulations.

Installation and configuration of the Mi Fitness application
The foundation for working any Xiaomi watch is the correct pairing through the mobile application. At the moment, the main tool is Mi Fitness (formerly known as Zepp Life for some old models, but new ones require Mi Fitness).
The synchronization process requires Bluetooth enabled and geolocation on your smartphone. Once the application is launched, you press the Add Device button and select your model from the list. It is important not to try to save the clock through the standard Bluetooth menu of the phone settings, this will lead to a connection error. The whole process must be initiated strictly from the application.
During the setup, the system will request permission to access contacts, microphone and notifications. Without these rights, the clock will be severely curtailed: you will not be able to see incoming calls or messages from messengers.
☑️ Checking before synchronization
If the installation process is 90% stalled, try restarting both devices and disabling the VPN if it is active.Sometimes Android antivirus programs can block device search, so add the app to the exceptions.
Basic configuration of the interface and dials
Personalization starts with a dial. Unlike simple trackers, Xiaomi watches allow you to set not only static images, but also complex animated dials with display of weather, pulse and steps in real time, which can be changed either through the app in the section “Dials”, or by long pressing on the screen of the watch itself.
The app menu is also customizable. You can choose to display as a list or a grid of icons. For ease of use, you can configure "Favorites" with one hand, which will be available by swipe sideways or through a programmable button, which allows you to quickly start a stopwatch or flashlight.
Screen brightness and backlight timeouts are critical parameters for the balance between readability and battery. Automatic brightness control works quite correctly, but in bright sun conditions it is better to force the maximum value. Raising the wrist to activate the screen can be adjusted to the sensitivity of "High" or "Low" depending on your manner of movement.
Set up notifications and calls
One of the main functions of a smartwatch is to stay connected without a phone. In the Mi Fitness app, under the "Application Notifications" section, you can choose which programs will duplicate messages on your wrist.
For Android users, Quick Answers (depending on the model and OS version) is available. You can customize template phrases that will be sent to the interlocutor when an incoming call or message is sent. On iOS, this feature is often not available due to the limitations of the Apple operating system.
If the watch supports Bluetooth calls, make sure that the phone settings in the Bluetooth section for connected watches activate the "Sounds" and "Contacts" points, which will allow you to synchronize the phone book and see the names of the callers, not just the numbers.
⚠️ Note: Text messages from WhatsApp and Telegram may not be displayed in full due to the privacy policies of these messengers, showing only “New message».
Health monitoring and sports regimes
The accuracy of the measurements depends on the correctness of wearing. The watch should fit tightly to the wrist, but not squeeze it, located 1-2 cm above the bone. The sensors on the back should be in constant contact with the skin. For maximum accuracy of measuring pulse and SpO2 (blood saturation with oxygen), it is recommended that you do not talk during the measurement and keep your hand still.
There are over 100 sports modes available in the app, and for professional training, you can set your target heart rate zones and get voice notifications when you exceed them, and the automatic activity detection feature is also useful: if you start walking fast, the watch will suggest you turn on walking tracking.
Sleep data is analyzed for REM sleep and deep sleep and daytime sleep, but algorithms can be wrong if you just lie still, and women's health or stress needs to be properly maintained, or watches must be worn all the time.
How to improve the accuracy of the pulse meter?
Energy efficiency and battery maintenance
The lithium polymer battery in Xiaomi watches is sensitive to deep discharges and extreme temperatures. To extend the battery life, it is not recommended to discharge the device to 0% regularly. The optimal charging mode is to charge with 15-20% of the remainder. Full charging takes about 2 hours, after which the watch is better removed from the dock.
The Always On Screen (AOD) function has a significant impact on autonomy, and its activation reduces the time of operation by 2-3 times. If you don't need to see the time constantly, you should use the Wrist Raising mode, and the constant pulse measurements every minute and the use of GPS without your phone are also energy-intensive.
Use only original or certified chargers. The charging current should not exceed the recommended values (usually 1A), otherwise the power controller may limit the charge rate or overheat.
💡
Keep your watch with a charge of about 50-60%, unless you plan to use it for a long time (more than a month), which will prevent deep discharge and battery degradation.
Frequent problems and ways to solve them
Users may experience time or steps desynchronization, most often by rebooting the clock through the Settings menu → System → Reboot or reconnecting Bluetooth. If the steps are not recorded, check if access to physical activity is disabled in the settings of the smartphone itself.
Wi-Fi connectivity problems (for models with this feature) are often solved by resetting the network settings or using a 2.4 GHz network instead of 5 GHz, as many IoT devices do not support the latest standard.
If the touch screen is delayed, check for protective film or contamination, and in rare cases, sensor calibration is required, which is done through an engineering menu (not available on all models) or firmware update.
💡
Most software failures are eliminated by simply restarting the device or reconnecting the application, do not rush to carry the gadget to the service.
