In today’s wearable electronics world, smartwatches are no longer just a smartphone addition, becoming full-fledged gadgets for health and productivity. Xiaomi, which offers a wide range of models under the Mi Band, Amazfit and Xiaomi Watch brands, is rightly considered the leader in the segment of budget and mid-budget devices. Users often underestimate the potential of these devices using only a small part of the available functionality, although the capabilities of the devices are much broader than simple display of time.
The main purpose of this article is to get a closer look at what current models can do and how they can improve your quality of life, and we will discuss the accuracy of sensors, the specifics of the Wear OS and Proprietary OS operating systems, and the nuances of integration with the smart home ecosystem, and understanding these aspects will help you make informed choices when buying or making the most efficient use of an existing device.
Many people mistakenly believe that the difference between a fitness bracelet and a full-fledged watch is only in the screen, but that's not true. The architecture of more advanced models allows you to install third-party apps, make calls, and even pay for purchases. Let's figure out what tools are hiding under a stylish case and how to use them correctly.
Health monitoring and sports tracks
The main feature most users buy wearable electronics for is activity tracking. Xiaomi’s current models are equipped with next-generation optical pulse sensors that provide high-precision measurements even under intense stress. PAI (Personal Activity Intelligence) algorithms analyze heart rate data and convert it into a comprehensible index to show whether you’ve moved enough to maintain your health.
And it's important to note that the monitoring system works in the background, producing detailed statistics for the day, week and month, and you can track not only steps, but also blood oxygen levels (SpO2), which is especially true for people who are mountaineering or who are monitoring their condition during illness, and there's a stress tracking feature based on heart rate variability.
⚠️ Attention: For proper operation of the sensor SpO2 It is necessary to fit the strap tightly to the wrist and maintain the immobility of the hand during the 15-30 seconds during measurement.
An extended package of more than 100 sports modes is available for athletes; the watch automatically recognizes the type of activity, whether it is running, swimming or cycling, and begins recording workouts; advanced models have a VO2 Max function that assesses aerobic endurance, and recommendations for recovery after exertion.
- 🏃♂️ Automatic definition of 6 main sports (running, walking, cycling, ellipse, rowing, jumping).
- 💧 Waterproof up to 5 ATM allows you to swim in the pool and take a shower without removing the device.
- 🧘♀️ Breathing and yoga regimes with voice and vibrational prompts.
- 🩸 Round-the-clock pulse monitoring with warning of critically high or low values.
All data is synchronized with Mi Fitness (formerly Zepp Life), which builds detailed graphs, which allows you to analyze progress and adjust your training plan, and for professional athletes, export statistics in TCX or GPX format are available for further analysis in specialized software.
Smart Notifications and Communication
The second critical aspect is communication with the outside world. Xiaomi smartwatches take on the role of the second screen of your smartphone, displaying notifications from messengers, social networks and email clients. You can quickly glance at your wrist to understand the importance of a message without taking your phone out of your pocket. This greatly increases digital hygiene and helps you stay in focus.
In support models SIM-With a card or Wi-Fi connection, you can expand your phone to full-fledged calls, and with a built-in speaker and microphone, you can talk right from the clock, which is convenient in situations where the phone is in your bag or in another room. The quality of communication depends on the Bluetooth version and the availability of the module. LTE modified.
In addition to the incoming watch, you can control the music playback on your smartphone, you can switch tracks, pause or adjust the volume directly from your wrist. In some regions, the function is supported. NFC-Payment via Mi Pay or third-party apps, which turns the watch into a digital wallet.
- 📱 Quickly view notifications from WhatsApp, Telegram, Viber and system applications Android/iOS.
- 🎵 Remote control of the smartphone media player and the ability to store music in the memory of the clock.
- 🗣️ Voice assistants (Google Assistant, Alexa or Xiao) AI) setting timers and searching for information.
- 🔦 Built-in flashlight and the "Find the phone" function with a beep.
It’s worth mentioning the quick response feature, too. Although a full keyboard isn’t available in all models, you can always send a pre-prepared message template or use voice input that converts speech into text with high accuracy.
Navigation and autonomy
One of the key challenges in wearables has always been autonomy, and Xiaomi has managed to balance functionality with time. With energy-efficient processors and optimized operating systems, most models last between 7 and 14 days in active use, which can last up to a month in hours only.
For outdoor enthusiasts, the built-in GPS module is critical. It allows you to capture a route without being tied to a smartphone. You can leave your phone at home for a run, and all distance and pace data will be recorded accurately. Support for global satellite systems (GPS, GLONASS, Galileo, Beidou) provides fast cold start and accurate positioning even in urban settings.
💡
For maximum charge savings, turn off the permanent pulse measurement (leave the interval 10-30 minutes) and the "Always-on Display" function if it is not critical.
Charging devices is also not a problem. Magnetic docks charge the gadget to 100% in about 1.5-2 hours. Some flagship models support wireless charging, which adds convenience to everyday use. The energy optimization system automatically reduces brightness and turns off unnecessary functions when battery power is low.
| Model | Working hours (typical) | Opening hours (GPS) | Charging time. |
|---|---|---|---|
| Xiaomi Watch S1 | 12 days | 24 hours | ~2 hours |
| Mi Band 8 | 16 days | 13 hours | ~1 hour |
| Redmi Watch 3 | 10 days | 18 hours | ~1.5 hours |
| Xiaomi Watch 2 Pro | up to 5 days (Smart) | 20 hours | ~1.5 hours |
It is important to understand that the actual operating time depends on many factors: the brightness of the screen, the frequency of pulse measurements, the number of notifications and the ambient temperature. In winter, in the cold, the capacity of a lithium polymer battery can temporarily decrease, which is the norm for the chemistry of such batteries.
Integration with a smart home
Xiaomi Home ecosystem owners will appreciate the ability to control a smart home right from the wrist. The watch acts as a remote control, allowing you to turn on the lights, check the security cameras or run robot vacuum cleaners, which is especially convenient when the phone is far away or in your pocket.
Setting up automation scripts allows you to create complex chains of action, for example, if you raise your hand with the clock in the morning, you can automatically start the coffee maker and open the curtains (if you have compatible equipment), to implement such functions, devices must be connected to the same network and Mi Home account.
Compatibility with third-party systems
The watch can also act as a trigger for scenarios, and a drop sensor or a sudden change in heart rate can trigger a notification to family members, making wearables an important safety feature, especially for older people or children.
- 🏠 Managing lights, sockets and climate technology through the Mi Home app.
- 📹 Viewing the image from IP-Real-time surveillance cameras.
- 🚪 Receiving notifications about opening smart doors and windows.
- 🤖 Run the scripts "I'm Home", "Cinema", "Sleep" with one touch.
Personalization and design
Visuals are as important to many users as functionality. Xiaomi offers a huge library of watch faces. You can choose from classic analog arrows, real-time sports data, anime, or even upload your own photos. The Watch Face Store has thousands of options, many of which are free.
Physical customization is also possible through interchangeable straps, standard mounting allows you to quickly change the style of the device, from a silicone sports version to a leather belt for a business suit or metal Milanese weaving. The cases of flagship models are often made of stainless steel or titanium, which adds premium.
⚠️ Note: When buying third-party straps, make sure the width of the mount (usually 18, 20 or 22 mm) matches your watch model exactly, otherwise installation will not be possible.
The interface allows you to adjust the order of the tiles (widgets) on the home screen. You can take forward the most important functions for you: weather, pulse, barometer or calendar. Animations of transitions in new versions of firmware have become smoother, and the response of the sensor has improved, making interaction with the device pleasant.
💡
Personalization is not just beautiful, it is a way to customize the device for specific tasks, leaving only the necessary functionality on the screen.
Compatibility with operating systems
When choosing a watch, the question of compatibility with a smartphone is often raised. Xiaomi devices are divided into two main categories: those running on proprietary OS (HyperOS, MIUI for Watch) and on the basis of Google Wear OS. The former are highly autonomous and work with both Android and iOS, but have limited application functionality. The latter are full-fledged minicomputers, but they are focused primarily on Android.
For iPhone (iOS) users, it is important to know that the functionality of the watch on Wear OS It may be limited, such as the inability to respond to a message or use NFC-However, basic tracking and notification functions are stable, Android smartphones are minimal, and all settings and synchronization of contacts are available.
Installation and configuration is done via the Mi Fitness app (for new models) or Zepp Life app (for old wristbands and watches) and takes a couple of minutes to download the app, register an account and scan. QR-The system itself will suggest updating the firmware to the current version, which is recommended to do immediately to fix bugs.
☑️ Pre-purchase check
Regular firmware updates (Firmware) bring new dials, bug fixes and sometimes new features. Xiaomi actively supports its devices by releasing security patches and algorithm improvements for several years after the model's release.
