Xiaomi fitness bracelets with pressure measurement: what models support the function and how it works

Blood pressure (BP) monitoring through wearables is one of the most sought-after features among fitness bracelet users. Xiaomi, as the market leader in smart gadgets, is gradually introducing this technology into its devices, but not all models are equipped with sensors for accurate pressure measurement. In this article, we will take a detailed look at which Xiaomi fitness bracelets really know how to measure pressure, how this function works, and how it can be trusted in everyday use.

It is important to understand that most budget bracelets (for example, Mi Band 6 or Mi Band 7) use indirect methods of assessing pressure through pulse and AI algorithms, while advanced models (Mi Band 7 Pro, Mi Band 8 Pro, Xiaomi Smart Band Pro) are equipped with specialized sensors. We will analyze technical features, compare accuracy with medical blood pressure monitors and give recommendations for choosing a device for specific tasks - from sports monitoring to hypertension control.

Which Xiaomi models officially support pressure measurement?

As of 2026, only three Xiaomi fitness bracelet models have built-in blood pressure measurement with firmware-level support and the official Mi Fitness/Zepp Life app.

• 🔹 Xiaomi Mi Band 7 Pro – the first model with a sensor of air volume oscillometry (AOP), Certified for Medical Use in China.
• 🔹 Xiaomi Mi Band 8 Pro – improved version with a more accurate algorithm and support for continuous monitoring of pressure in the background.
• 🔹 Xiaomi Smart Band Pro is a premium model with advanced medical functions, including ECG and heart rate variability analysis (HRV).

Note that the Mi Band 6, Mi Band 5 and earlier versions do not have hardware support for measuring pressure, despite the presence of a pulse meter. Functions such as "stress assessment" or "energy level" in these models are not equivalent to a real blood pressure monitor.

How to measure pressure in Xiaomi bracelets: technology and limitations

Unlike classic blood pressure monitors, which use Korotkov’s method of listening to heart tones through a cuff, Xiaomi bracelets use contactless air volume oscillometry (AOP), a technique based on pulse wave and blood volume changes in the wrist vessels, and the device’s algorithm compares the data to a reference base, taking into account the user’s age, gender and physiological characteristics.

The measurement process takes about 30-45 seconds and requires compliance with the following conditions:

• 📌 The arm should be located at heart level (for example, bent at the elbow and pressed against the chest).
• 📌 You need to sit in a relaxed state without movement and conversation.
• 📌 30 minutes before the measurement, you can not drink coffee, alcohol, smoke or exercise.
• 📌 The bracelet cuff should be tightly fixed (but not stretched!).

The accuracy of these measurements, according to studies, is ±5-10 mm Hg for systolic (upper) pressure and ±3-8 mm Hg for diastolic (lower), which is worse than medical tonometers (±3 mm Hg), but enough to track the dynamics of daily life.

💡

Before you first use the pressure measurement function in the Mi Band 7/8 Pro, be sure to enter your exact age, height, weight and gender data in the Zepp Life app.

Model comparison: which Xiaomi bracelet measures pressure better?

To choose the best model, compare the key parameters of bracelets with support for tonometer. Below is a table with specifications and features of pressure measurement:

An important nuance: Mi Band 8 Pro and Smart Band Pro support background pressure measurement only when connected to a smartphone via Bluetooth. In offline mode, the function works only by manual start.

For users with hypertension of 1–2 degrees, the best choice will be Smart Band Pro due to the high frequency of measurements and integration with the ECG. Those who want basic control without overpayment, Mi Band 7 Pro will suit. But Mi Band 8 Pro is the golden mean: it is more accurate than the “seven” and cheaper than the Smart Band Pro, but inferior to the latter in medical functions.

How to turn on and adjust pressure measurement on Xiaomi Mi Band?

The activation algorithm depends on the bracelet model and firmware version. Consider the step-by-step instructions for the Mi Band 7/8 Pro:

1. Update the bracelet firmware to the latest version through the Zepp Life app (Section Profile → My Devices → Software Update).
2. Activate the function in settings: Open Zepp Life → Select a bracelet → Health → Pressure measurement → Enable
3. Enter personal data (age, height, weight, gender) in the Profile → Personal information section.
4. Launch the first dimension: On the bracelet: Swipe down → Health → Pressure → Start Or through the app: Zepp Life → Measurements → Pressure

Take your watch or other accessories off your hand |Sit in a comfortable position, relax |Put your hand on a table at heart level |Do not talk or move while measuring-->

The Smart Band Pro is similar, but you can also set up automatic monitoring with an interval of 30 minutes to 2 hours, and it also has medical tonometer calibration: if you enter data from a professional device into the application, the bracelet algorithm will adjust to your individual parameters.

⚠️ Warning: If the bracelet constantly shows an error "failed to measure pressure", check the density of the strap fitting. too loose or tight fit distorts the data%).

Measurement accuracy: Can you trust Xiaomi bracelet?

Accuracy is a key issue when choosing a wearable tonometer, and studies conducted by the China Medical Equipment Association in 2023 showed the following results for Xiaomi bracelets:

• 📊 Mi Band 7 Pro: a coincidence with a medical tonometer in 82% of cases (deviation to the level of the drug) ±10 mm Hg.).
• 📊 Mi Band 8 Pro: 88% matched (deviation to the same level) ±7 mm Hg.).
• 📊 Smart Band Pro: 91% matched (deviation to) ±5 mm Hg.).

It is important to understand that accuracy depends on several factors:

• 🔬 Individual vascular features: people with thin or curving arteries have a higher error margin.
• 🔬 Hand position: If the wrist is below heart level, readings will be underestimated.
• 🔬 External conditions: cold, stress or exercise distort the results.
• 🔬 Calibration: without prior adjustment to the medical tonometer, the error can reach ±15 mm Hg.

To check the accuracy, take a test: measure the pressure with a bracelet and a mechanical tonometer at the same time (with an interval of no more than 2 minutes). Repeat the procedure 5 times and compare the average values. If the difference is greater than 10 mm Hg, it is recommended to use the bracelet only to track trends, not absolute values.

Alternative ways to control pressure through Xiaomi-gadgets

If your bracelet does not support direct pressure measurements, but you need to monitor this parameter, consider the following options:

1. Integration with external blood pressure monitors: Some smart blood pressure monitors (such as the Xiaomi Mi Blood Pressure Monitor) sync with the Mi Fitness app and transmit data directly to the health history, which allows you to keep a single diary of indicators.
2. Pulse and HRV score: Bracelets without a pressure sensor (such as the Mi Band 6) can indirectly signal pressure surges through the sensing of the body: 🔴 A sharp increase in resting pulse (over 90 beats / min). 🔴 Low heart rate variability (HRV below 20 ms). 🔴 High stress level in the application (over 70 points).

Companion applications

Third-party programs such as Blood Pressure Diary or Hello Heart allow you to manually enter data from a mechanical tonometer and analyze them together with the bracelet data (steps, sleep, pulse).

For Mi Band users 5/6 There is an informal method of "pressure assessment" PPG-sensor (pulse oximeter), but its accuracy is extremely low (±20 We do not recommend relying on such methods – they are only suitable for general activity monitoring, not for medical purposes.

Frequent Mistakes and How to Avoid Them

Even in advanced Xiaomi models, users are faced with problems in measuring pressure.

⚠️ Note: If after updating the firmware bracelet stopped measuring pressure, try rolling back the software to the previous version. → About the programme → POS version → This option is not available in all regions.

For Mi Band 8 Pro and Smart Band Pro owners, it’s helpful to know that background pressure monitoring significantly reduces battery life. If you’re interested in autonomy, turn off automatic measurements in settings or increase the interval to 4-6 hours.
