What Xiaomi Smart Watch Shows: A Complete Guide to Functions and Hidden Data

Xiaomi’s smartwatches are no longer just a time-reflection accessory, and today they are full-fledged health trackers, sports assistants, and even minicomputers on the wrist. 20-30% This article will look at the data that these devices are able to capture and analyze, and in this article, we will look at the information that Xiaomi watches display on the screen and in the accompanying Mi app. Fitness/Zepp Life, How to Interpret It and Where to Look for Hidden Metrics.

From basic metrics like step counts to advanced phase-by-phase sleep tests or blood oxygen levels, current models (Mi Band 8 Pro, Xiaomi Watch 2 Pro, Redmi Watch 4) collect dozens of parameters. But not all data are equally useful: some require calibration, others depend on external factors, and still others can be misleading if misinterpreted, and we will help you figure out which metrics should be considered for health control and which are purely reference.

Basic indicators: time, steps and activity

Even Xiaomi’s most budget models (such as the Mi Band 7) display three key metrics on the home screen: current time, number of steps and distance traveled, which are synchronized with the app and participate in the formation of daily reports.

  • ⏱️ Time can be synchronized not only automatically. GPS, But also manually – this is important for models without a module GPS (For example, Redmi Watch 3 Active. Go to Settings β†’ System system β†’ Date and time.
  • πŸ‘Ÿ Steps are considered to be error-prone. Β±10-15% To improve accuracy, you need to specify the step length in the application profile (measured experimentally: pass through the application). 10 Meters and count the number of steps).
  • πŸ“Š The activity is divided into light (walking) and intense (running, cycling). β†’ Activity targets.

It's important to understand that step data is not just a number for reporting, it's used to calculate calories, measure activity levels, and even influence sleep recommendations. 5 000 Steps per day, the app may advise you to go to bed 30-60 minutes early.

Health monitoring: pulse, blood oxygen and stress

One of the key functions of Xiaomi’s smartwatches is to monitor physiological parameters, so let’s look at what the sensors measure and how to interpret the results correctly.

Heart rate (HR) is measured by an optical sensor every time 5-30 minutes (depending on model and settings) Normal values:

  • πŸ’€ In a dream: 40-60 strike/min
  • 😴 At rest: 60-80 strike/min
  • πŸƒ At moderate loads: 100-140 strike/min
  • ⚠️ Limit loading: 180-220 impacts/min (depending on age)

If the clock shows a heart rate above 100 beats at rest for more than 10 minutes in a row, this may indicate stress, fatigue or problems with the cardiovascular system. However, a single increase in heart rate is not a diagnosis - an accurate assessment requires observation in dynamics (at least 7 days).

ParameterNormal valuesWhat to do with deviations
SpOβ‚‚ (oxygen)95-100%If the values are below 92%, check the density of the watch, avoid measurements in the cold.
Stress level0-39 (low-key), 40-59 (middle-class)At values above 60, breathing exercises or meditation are recommended.
Respiratory rate12-20 breathMore than 25 breaths/min may indicate hyperventilation or exercise
Skin temperature32-36Β°C (individually)Sharp changes of more than 1Β°C may signal the onset of disease

Particular attention should be paid to the function of measuring the level of oxygen in the blood (SpOβ‚‚). In Xiaomi Watch 2 Pro and later, it works in the background, but for accuracy it is required:

  1. Sit still for at least 3 minutes before measurement
  2. Keep your hand at heart level.
  3. Avoid bright sunlight on the sensor

πŸ’‘

If the clock is constantly showing SpOβ‚‚ Under 95%, try changing your arm (right hand is often more accurate because of better blood flow) or check the band density.

Sleep analysis: phases, quality and recommendations

Xiaomi smart watches analyze sleep in four main phases: wakefulness, light sleep, deep sleep and sleep. REM-phase (rapid eye movement) for accurate tracking:

  • πŸ›Œ Wearing a watch before bed (for the first time) 30-60 minute)
  • πŸ“΅ Enable the "Do Not Disturb" mode on your smartphone
  • πŸ”‹ Charge the clock to at least 30% (for models with a AOD)

Optimal distribution of sleep phases for adults:

  • πŸŒ™ Deep sleep: 15-25%
  • 🌌 Light sleep: 50-60%
  • πŸ‘οΈ REM-phase: 20-25%

If the clock shows less than 10% of deep sleep or more than 30% of wakefulness, it may indicate:

⚠️ Chronic sleep deprivation (less than 6 hours of deep sleep per week) increases the risk of cardiovascular disease by 48% according to WHO. If the clock records such indicators for more than 3 days in a row, it is recommended to consult a sleep specialist.

The Zepp Life app provides additional sleep metrics:

  • πŸ“ˆ Sleep index (0 to 100) – comprehensive quality assessment
  • πŸ›οΈ Time of falling asleep (norm: up to 20 minutes)
  • 😴 Frequency of awakenings (optimal: 0-2 nightly)
  • 🌑️ Skin temperature in your sleep (helps to detect night sweats)
How does the clock determine the phase of sleep?
Xiaomi devices use a combination of sensors: accelerometer (movement), gyroscope (body position), heart rate sensor and SpOβ‚‚. The algorithm analyzes micromotion, pulse, and breathing, for example, deep sleep is defined by slowing the pulse rate. 20-30% from daytime level and lack of movement more 20 minute.

Sports modes: what to track the clock during training

Depending on the model, Xiaomi watches support from 30 to 150 sports modes. Let's take a look at what data is captured in the most popular types of activity:

SportTracked parametersAccuracy of measurements
Run.Distance, pace, heart rate, calories, steps, contact with the groundΒ±5% (c) GPS), Β±15% (no) GPS)
SwimmingNumber of swimming pools, style, heart rate, SWOLF (efficiency)Β±10% (only for models with 5) ATM)
CyclingSpeed, distance, heart rate, cadence (only with an external sensor)Β±3% (when connected to a smartphone)
Gym roomHeart rate, calories, activity time, types of exercise (autodetermination)Β±20% (depends on the accuracy of the exercise recognition)

For maximum accuracy of sports measurements:

  1. Activate. GPS on a smartphone (if there is no built-in module in the watch)
  2. Calibrate the pedometer before your first workout (walk 100 meters with the clock)
  3. Wear your watch on 2-3 finger above the wrist bone for better sensor contact

The parameter deserves special attention. VOβ‚‚ max (maximum oxygen consumption), which is available in Xiaomi Watch 2 Pro and later:

  • πŸƒ Below 30 – poor preparation (risk of health problems)
  • πŸ§— 30-40 β€” Medium level (suitable for amateur training)
  • 🚴 40-50 β€” Good training (for regular athletes)
  • πŸ… Over 50 – excellent endurance (professional level)

πŸ’‘

VOβ‚‚ max is the only measure that is directly correlated with life expectancy. VOβ‚‚ max per 1 unit reduces mortality risk by 15%.

Smart Features: Notifications, Weather, and Device Management

In addition to health and sports, Xiaomi watches are a smart assistant.

  • πŸ“± Notifications from messengers, social networks and mail (with the possibility of a quick response by voice on some models)
  • 🌦️ Weather for now. 3-5 Days with hourly detail and UV radiation index
  • 🎡 Music control (track switching, volume control)

Hidden Opportunities: What Xiaomi Watches Show, But Don’t Show

Many users are unaware that Xiaomi watches collect and display data that is not obvious at first glance.

  • πŸ“Š Heart rate analysis: The Zepp Life app has a section called Heart Health that shows heart rate variability (HRV), a key indicator of stress resistance: 20-100 miss.
  • 🩺 Biological age assessment: based on sleep, activity and heart rate, the clock calculates "body age." The difference with passport age over 5 years signals the need for lifestyle changes.
  • 🚢 Gait analysis: Walking/running captures stride length, symmetry and ground contact (useful for identifying joint problems).
  • 🌍 Meteosensitivity: Matching weather changes to your health (available in Zepp Life under Health").

To access this data:

  1. Open the Zepp Life app
  2. Go to the Health or Analytics section.
  3. Select "Reports" or "Statistics"
  4. Scroll down to the "Additional Metrics" section.

The recovery score, which shows how prepared your body is for your next exercise, is particularly useful.

  • Muscle fatigue level
  • The quality of the last sleep
  • Stress levels in the last 24 hours
  • Heart rate at rest

⚠️ Note: If the watch shows a "Recovery score" below 50%, The risk of injury during intense training increases in 3 In this case, it is recommended to either postpone the training or reduce the load on the 30-40%.

Customization of dials: what can be displayed on the main screen

The dials on Xiaomi watches are not only design, but also a tool for displaying the most important information. Depending on the model, you can show 3 to 8 different metrics on the home screen at a time.

FAQ: Answers to Frequent Questions About Xiaomi Watches

Why does a watch show a different number of steps compared to a smartphone?
The difference is due to different calculation algorithms: Xiaomi watches use accelerometer and gyroscope data, and smartphones often rely on the data of the accelerometer and gyroscope. GPS To improve accuracy: Calibrate the step length in the app Wear the watch on a non-dominant hand (left hand for right-handers) Update the firmware to the latest version Tolerable error between devices to 15%. If the difference is greater, reset the pedometer settings in Profile β†’ The device β†’ Pedometer data reset.
How does a watch measure stress levels and how accurate is it?
Xiaomi watches assess stress by heart rate variability (HRV) - the change in the intervals between heartbeats. The algorithm analyzes: Heart rate Regularity Rate Response to external stimuli Accuracy of measuring stress - about 70-80% For more accurate results: Wear watches at least 5 Measure stress at the same time: Eliminate caffeine and alcohol 2 hourly
Can we trust the calorie data that the clock shows?
Calorie counts on Xiaomi watches are calculated using the formula that takes into account: Calories = (MET Γ— Weight. Γ— Time) / 60 where MET β€” The metabolic equivalent of the problem is the error 20-30% Due to: Inaccurate weight indication in profile Mistakes in activity recognition Individual metabolic features For more accurate count: Regularly update the weight in the profile Use the chest pulsemeter for calibration Compare data with other trackers (for example, Garmin)
What if your watch shows an unrealistically high pulse (over 200 beats)?
This is a typical optical sensor error that occurs due to: Poor skin contact (weakened strap, dirt on the sensor) Hand movements during measurement of Low ambient temperature (below 10)Β°C) Tattoo or scar in the sensor area To fix: Wipe the sensor with an alcohol napkin Tighten the strap so that the clock does not shift Repeat the measurement after 5 minutes at rest If the error repeats, reset the sensor settings in Profile β†’ The device β†’ Sensor reset
How to export data from a Xiaomi watch to a doctor?
To provide your doctor with sleep, pulse, or activity data: Open the Zepp Life app Go to Health or Activity Select the desired period (week/month) Click Export or Report Select the format (PDF or CSV) The report will include: Heart rate charts with load marks Sleep phases Activity and stress levels Training statistics For models with ECG (For example, Xiaomi Watch 2 Pro can be exported and electrocardiogram in the format PDF.
