Smart watches Xiaomi: functions and why they need the owner

Wearable electronics have ceased to be just a fashion accessory and have become a full-fledged center for managing health and digital user profile. Xiaomi smart watches are leading the market due to the optimal ratio of price, functionality and autonomy. Android smartphone owners and iPhone owners often choose this brand, wanting to get the maximum opportunities without overpaying for premium marketing of other companies.

Many users buy a gadget without realizing half of its capabilities, using the device only as a notification or pedometer. Xiaomi Mi Band and Xiaomi Watch series offer a much deeper toolkit for lifestyle analysis. In this article, we will discuss in detail what tasks these devices solve and how they can become indispensable assistants in everyday routine.

Understanding the real purpose of each sensor and software module will allow you to customize the device to your needs, and you will learn not just to wear a watch on your hand, but to use its potential to improve fitness and control the body.

Health monitoring: beyond just counting steps

The main feature most users buy wearables for is physical activity tracking. However, modern models like the Xiaomi Watch S3 or Mi Band 8 have gone far beyond just counting steps taken. The built-in PAI algorithms measure your activity not by the number of steps but by their effect on the cardiovascular system, turning complex medical data into a comprehensible index.

The optical pulse sensor works in the background, taking readings every few minutes or continuously depending on the settings, which allows you to detect rhythm abnormalities that may not be noticeable in a calm state. If the device detects a sharp increase in heart rate at rest, it will send a warning, which can be an early signal of health problems.

The function of monitoring blood oxygen levels (SpO2) deserves special attention. Measurement of saturation is especially important for people who are engaged in mountaineering, running long distances, or recovering from respiratory diseases. The watch can automatically measure this indicator during sleep, providing a complete picture of the body's oxygen saturation at night.

The list of health parameters monitored is constantly expanding:

• 🫀 Continuous monitoring of stress based on heart rate variability (HRV).
• 🌬️ Breath control with guided exercises for relaxation.
• 🩸 Menstrual cycle tracking with predictions and reminders.
• 💤 Detailed analysis of sleep phases, including REM-nap.

⚠️ Attention: Health data provided by smartwatches are informative and not a medical diagnosis. If critical abnormalities are detected, always consult your doctor.

Sports regimes and professional tracking

For people who are active, multisport modes are becoming the main tool for training, and depending on the model, the watch can support 30 to 150 different types of activity, and it's not just a timer, but a complex algorithm that analyzes the biomechanics of movement, cadence (step frequency or pedals rotation), and pace.

Built-in GPS-The module (found in advanced models and watches, but not in basic fitness bracelets) allows you to track the route without having to bring your phone. The positioning accuracy in Xiaomi’s new chips has reached a level comparable to a specialized sports watch, which is critical for runners and cyclists analyzing their pace across different stretches of the distance.

After training, the data is synchronized with the Mi Fitness app (formerly Zepp Life), where detailed analytics are built, and you can see the real-time pulse chart, the load zone, and the calculated VO2 max, which is considered the gold standard for aerobic endurance.

The main opportunities for athletes include:

• 🏊 Automatic recognition of swimming style and counting strokes (with water resistance) 5ATM).
• 🏃 Voice prompts about pace and pulse while running.
• 🚴 Analysis of pedal efficiency and time of contact with the ground.
• 🧘 Yoga tracking with an assessment of stretching and holding poses.

Notifications and smartphone management

One of the key features that smartwatches are used for is the ability to stay connected without taking your phone out of your pocket. Synchronizing notifications allows you to see messages from messengers, social networks, emails and missed calls on your wrist. In models with a microphone and speaker (for example, the Xiaomi Watch 2 Pro), you can even answer calls directly from the clock via a Bluetooth connection.

Controlling a media player is another convenient use case: You can switch tracks, pause music, or adjust volume without interrupting your workout or walk, and the watch can control playback on the smartphone itself, acting as a remote control.

Find the phone is often a life-saving feature, and when activated through a watch menu or app, the smartphone starts to emit a loud signal, even if it is in silent mode, eliminating the need to frantically search for the gadget under the couch or in the bag.

Opportunities for interacting with a smartphone:

• 📱 View text messages and email (editing is available only in some models).
• 📷 Remote control of the smartphone camera (remote shutter mode).
• 🔔 Set up vibration patterns for different contacts.
• 🌐 Xiaomi Smart Home Management (Switching off lights, launching a robot vacuum cleaner).

Comparison of models: what different series can do

The company’s line of wearables is highly differentiated, and it’s important to understand the differences to pick a device for your tasks. Budget activity trackers focus on basic monitoring, while full-fledged smartwatches offer an operating system and install third-party apps.

The Mi Smart Band series (formerly the Mi Band) are lightweight, stretched-screen fitness trackers. They are ideal for those who want to forget about daily charging and get basic statistics. The Xiaomi Watch series (S, S Pro, S Active) is a round watch with a classic design, often with a metal body, running on Wear OS or proprietary HyperOS, which gives access to maps and app stores.

⚠️ Attention: Functional NFC Global versions often do not support bank cards of the Russian Federation and CIS countries, working only as a transport card or access key in certain ecosystems.

Autonomy and energy saving regimes

Xiaomi’s great advantage over its competitors is its high autonomy, which, thanks to software optimization and the use of energy-efficient AMOLED screens, saves users from the “charging fever” that is typical of Apple Watch or Wear OS devices of other brands.

The watch has multiple modes of operation. Standard mode balances functionality and energy consumption. Watch only turns off all smart functions, leaving only the display of time, which allows the device to run for up to 25 days. Energy saving mode limits background measurements and synchronization frequency.

Charging speed also plays a role. Current models support magnetic charging, which allows you to replenish your energy supply from 0 to 100% in about an hour, which means that even a quick recharge during the morning shower or while you eat breakfast can add several days of battery life.

Factors affecting working hours:

• 🔋 pulse rate (constant monitoring consumes more than interval monitoring).
• 📡 Number of notifications and Bluetooth connections received.
• 💡 Screen brightness and use of Always-On Display (Constantly on screen).
• 🏃 Active use GPS-tracking during training.

💡

For maximum autonomy, turn off the wrist lift function and set the heart rate to Smart or 30 minutes, which can increase the work time to 20 days on a single charge.

Personalization and dials

Visuals are as important to many users as technical ones. The dial store in Mi Fitness or Zepp Life has thousands of options, and you can choose a strict analog style for the office, a bright digital for sports or a minimalist one for sleep.

The feature of creating your own dials allows you to use personal photos as a background, and advanced users can customize the displayed data (sets) by choosing the metrics that are important to you personally: weather, currency exchange rate, steps, pulse or calendar.

It takes seconds to change the style of the watch, so you can set the clock to change automatically depending on the time of day, or you can start the "Random Dial" feature, which will change the design every time you raise your hand, and it creates a sense of novelty without buying new accessories.

💡

The ability to quickly change the dials allows you to adapt the appearance of the watch to any style of clothing or situation, making one gadget a universal accessory.
