What smart watches Xiaomi Watch: functionality and capabilities

Modern wearables are no longer just a complement to a smartphone, becoming full-fledged stand-alone devices. Xiaomi Watch is a vivid example of such an evolution, offering users a wide range of tools for health, sports and everyday life. The question of what exactly these devices can do worries both potential buyers and owners who want to unleash the full potential of their gadget.

It's based on an operating system, whether it's Wear OS or proprietary MIOT, which has a direct impact on how you can install apps and customize the interface. It can track more than a hundred physical activities, monitor your heart rate around the clock, and even make calls without your phone, and understanding these capabilities will allow you to use the device more effectively in everyday scenarios.

In this article, we will take a closer look at key features, hidden features and technical nuances of operation, learn how to set up notifications, calibrate sensors correctly, and what the NFC module offers in specific models.

Health and biometric monitoring system

One of the main tasks that smart watches take on is continuous monitoring of body parameters. Xiaomi devices have an advanced algorithm for working with an optical pulse sensor that takes measurements at high intervals, which allows you to build detailed charts of heart rhythm at rest and during exercise. When the heart rate is released beyond the established norms, the device can give a vibration signal, warning the owner of excessive stress.

In addition to cardiac monitoring, a sleep tracker is an important element: it analyzes the phases of falling asleep, deep and REM sleep, as well as wakeful periods. This data provides a rest assessment and recommendations. For users monitoring their stress levels, a function is available to measure heart rate variability, which helps assess psycho-emotional state during the day.

• 🩸 SpO2 monitoring: measuring blood oxygen saturation in automatic or manual mode, which is especially important when playing sports or being in the highlands.
• 🧘 Breathing exercises: built-in breathing training programs to help reduce stress quickly and restore calmness.
• 👩 Women's calendar: menstrual cycle tracker with date predictions and reminders of important stages.

Special attention should be paid to the accuracy of the measurements. To properly work the sensors, you need to attach the strap tightly to the wrist, but not squeeze the skin. If you notice discrepancies in the data, try to wipe the optical sensor on the back with a soft cloth, since fat or sweat can distort the readings.

⚠️ Note: Data collected from the clock is informative and not a medical diagnosis.Do not use the device's readings to prescribe medications or treat diseases without consulting a doctor.

💡

For maximum accuracy of measurement SpO2 Keep your hand motionless at heart level for a while. 15-30 seconds.

Sports modes and activity tracking

The functionality of Xiaomi watches in the field of sports is striking. The basic model can support more than 100 training regimes, covering both popular areas such as running and swimming, and niche disciplines. When you start the activity on the screen, the key statistics are displayed: time, distance, pace and pulse zones. For professional athletes, it is important to be able to adjust the targets, for example, to reach a certain distance or burn a certain number of calories.

Built-in GPS-The module (depending on the version) allows you to record the route without having to bring a smartphone, which ensures high accuracy of the track even in the woods or in dense urban areas. After training, all data is synchronized with the application, where you can analyze the graph of speed, ups and pulse.

For swimmers, it's not just waterproofing that matters, it's the ability to record swims underwater, it recognizes swimming style, it counts strokes and it counts SWOLF, but it's worth remembering that the touchscreen underwater is less efficient, so it's often controlled by physical buttons.

• 🏃 Running courses: the ability to download routes or compete with virtual rivals in real time.
• 🏊 Water Lock: Automatically activate the screen lock mode when diving to prevent false pressing.
• 🚴 Cycling track: support for external cadence sensors and power via Bluetooth protocol.

⚠️ Note: Despite certification 5 ATM or IP68, It is not recommended to use the watch in a sauna, hot shower or when diving with scuba. Steam and high pressure can damage the adhesive joints of the body.

Smart Notifications and Communication

One of the most prominent features for the average user is the notification function: the watch broadcasts messages from instant messengers, social networks, email and SMS. Depending on the model and operating system, the functionality can vary. Wear OS devices allow you not only to read text, but also to respond to messages with voice, send emoji or use ready-made phrases. Simpler models are limited to displaying text.

An important option is the ability to manage calls. When an incoming call comes in, a vibration comes on the wrist, and the user can accept or reject the call. In models with a built-in speaker and microphone (for example, the Xiaomi Watch 2), you can have a full conversation without taking the phone out of your pocket. The quality of communication depends on the distance to the smartphone and the presence of interference.

The smartphone's media player has a separate widget that allows you to switch tracks, pause music, and adjust volume, which is convenient when the phone is in your bag or connected to a speaker, and you need to control playback quickly.

💡

The presence of the Wear OS operating system dramatically expands the possibilities of communication, allowing you to install third-party messengers and respond to messages right from the clock.

Payments and the NFC module

The presence of an NFC chip makes watches a convenient payment tool. Global versions often run Google Pay (now Google Wallet), which allows you to pay for purchases at terminals around the world. However, for users from CIS countries, it is important to support local payment systems. In Russia, for example, the watch can support Mi Pay or card emulation through third-party applications, if the region and device model allow.

The setup process usually takes a few minutes, you need to open the application on your smartphone, go to the payment section, add a bank card and verify through SMS or a bank application, and then you just need to hold your wrist to the terminal to pay.

In addition to payment, NFC can be used to access office buildings or public transport, as long as the city’s infrastructure supports appropriate encryption standards, and there is a Key feature that allows you to open compatible Xiaomi smart locks.

• 🏦 Security: Payments often require unlocking hours, which protects funds when a device is lost.
• 🚌 Transport cards: In some regions (e.g. China) the watches support virtual subway and bus maps.
• 🏠 Smart home: use NFC-tags to run scripts, for example, turning on the light when the clock touches the switch.

⚠️ Note: Payment may not be available in your area due to sanctions or bank policies.Always check the list of supported cards on the official website before buying.

Autonomy and energy saving regimes

The issue of autonomy is acute for all wearable electronics owners. Xiaomi standard smart watches when used actively (included Always-On Display, constant pulse monitoring, notifications) last from 2 to 4 days. GPS-tracking significantly reduces this time, as the geolocation module consumes a lot of energy.

To increase the operating time, the device has an energy saving mode, when it is activated, background processes are turned off, sensor measurement frequency is reduced, and notification functionality is limited. In extreme "Hours Only" mode, the device can last up to two weeks, displaying only the time and date.

Charging is done by magnetic docking. Full recovery takes about 1.5-2 hours. It is important to use original or certified cables, as poor-quality power supplies can damage the charge controller.

There is a myth that frequent charging of a lithium-polymer battery is harmful to it.Modern power controllers in Xiaomi watches are smart and prevent overcharging.However, for long-term battery health, it is not recommended to discharge the device to zero regularly.

• 🔋 Always-On Display: The constant display function reduces autonomy by about one 30-40%.
• 📡 Network search: If the Bluetooth connection to the phone is lost, the watch begins to actively search for the network, which quickly lands the battery.
• 🌙 Night mode: Automatically lowering brightness and turning off notifications at a given sleep time.

Personalization and interface settings

The look of the watch is something that the user interacts with all the time, allowing you to change dials, add complications (widgets), and customize the app menu. The dial store has thousands of options, from classic analog classics to informative digital displays with activity charts.

Customizing the menu allows you to bring the most important functions to the first screen, you can change the order of the icons, switch between the list and the grid view, and adjust the actions of the buttons. For example, a short press of the bottom button can trigger a specific sports mode or payment application, not a menu.

For people with visual impairments or just for convenience, you can adjust font size and contrast in different situations, and some models also have a wrist lift feature that wakes the screen when you look at it, and the sensitivity of this sensor can be adjusted to avoid accidental switching on.

The important aspect is time synchronization: the watch gets the exact time and time zone from the smartphone. When traveling to other time zones, the daylight/winter time and belt change occur automatically, without the need for manual reconfiguration, which eliminates confusion.
