The Xiaomi Mi Band 5 and Mi Band 6 fitness bracelets remain among the most popular wearables on the market due to a combination of affordable prices and rich functionality. At first glance, the difference between the models seems small - both devices retain a compact design, long autonomy and basic health monitoring capabilities. However, on closer inspection, it becomes clear that the Mi Band 6 has received a number of significant improvements that make it a more modern and convenient gadget.
If you are faced with a choice between these two models in 2026, it is important to understand exactly what changes Xiaomi made to the sixth version of the bracelet. Should you overpay for the updated model or Mi Band 5 is still a valid option? In this comparison, we will analyze all the key parameters from design and screen to sensor accuracy and software capabilities, and also answer the question: which bracelet is best for your tasks.
1. Design and Ergonomics: What has changed on the outside?
In terms of appearance, both models retain Xiaomi’s signature minimalist style, with the bracelet body made of polycarbonate with a matte surface and the strap made of hypoallergenic thermoplastic polyurethane (TPU).
- 🔹 The shape of the body: Mi Band 6 received slightly rounded side faces, which makes it more ergonomic when worn. Mi Band 5 body was completely rectangular with sharp corners.
- 🔹 Weight and dimensions: The sixth version is 1 gram lighter (12.8 g vs. 11.9 g) and 0.5 mm thinner, which is almost imperceptible in practice, but affects comfort with prolonged wear.
- 🔹 Strap fastening: The Mi Band 6 uses an improved fixing mechanism, which is less likely to be unbuttoned accidentally (relevant for active users).
- 🔹 Color options: Mi Band 6 palette wider - added shades "Ivyushka" (greenish) and "Orange sunset", while the fifth version was limited to classic black, blue and pink.
It is important to note that the bands from the Mi Band 5 are not compatible with the sixth model due to the changed mounting, which means that when you upgrade to the new version you will have to buy accessories again. On the other hand, Xiaomi offers a wide range of original and third-party straps for the Mi Band 6, including versions of silicone, nylon and even metal.
⚠️ Note: If you use the bracelet while swimming, note that the Mi Band 6 has improved leakage (5). ATM This means that you can safely avoid water when diving to a depth of 50 meters, whereas the Mi Band 5 is officially certified only for swimming in the pool.
2. Screen: Size, resolution and image quality
One of the most notable improvements in the Mi Band 6 — If the fifth version used the display. 1.1-inch AMOLED-resolution-screen 126×294 The sixth model, the sixth model, was 1.56-inch-screen 152×486 The difference in screen area is almost 50%, which significantly affects the usability of:
| Parameter | Mi Band 5 | Mi Band 6 |
|---|---|---|
| Screen diagonal | 1.1 inches | 1.56 inches |
| Permission | 126×294 px | 152×486 px |
| Pixel density (PPI) | ~290 PPI | ~326 PPI |
| Screen type | AMOLED | AMOLED (improved brightness) |
| Number of dials | ~100 | ~130 (including animated ones) |
The larger screen allowed Xiaomi to add new interface elements, such as the Mi Band 6 home screen displaying more information: besides time, date and steps, there is now room for weather, battery levels and notifications without having to scroll through menus, and support for Always-On Display (AOD) — a feature that many users of the fifth version lacked.
The brightness of the screen in the Mi Band 6 has been increased to 450 nits (versus 400 nits in its predecessor), which improves readability in direct sunlight. However, automatic brightness adjustment is still missing - it can only be adjusted manually through the wristband menu.
Sensors and Measurement Accuracy: Which is Better for Health?
Both models feature a suite of sensors to track activity and health, but the Mi Band 6 has several important improvements.
- 🩺 Optical heart rate sensor: The sixth version uses an updated version of the sensor PPG, Xiaomi claims that the error rate is reduced by 15% compared to the fifth model.
- 🌡️ Sensor. SpO₂ (Both models support oxygen measurement, but in Mi Band 6 the data processing algorithm is optimized for faster and more stable measurements.
- 🏃 Accelerometer and gyroscope: The sixth version adds a 6-axis sensor (versus the 3-axis sensor in the Mi Band 5), which improves the accuracy of tracking movements, for example, when running or swimming.
- 💤 Mi Band 6 not only analyzes sleep phases (REM, Light, deep), but also daytime sleep, and also offers recommendations for improving the quality of rest.
One of the key innovations of the Mi Band 6 is the stress sensor, which assesses the level of tension based on heart rate variability (HRV), a feature that is available in real time and can be useful for monitoring emotional state during the day.
However, not everything is so smooth: some users note that the measurement SpO₂ In Mi Band 6, it sometimes overestimates (e.g., 99% at 95% real) because of the algorithm's tendency to smooth out random fluctuations.

Functionality and programmatic capabilities
In terms of software, the Mi Band 6 offers more features, although the basic functionality remains similar. Both models work with the Mi Fitness app (formerly Mi Fit), but the sixth version supports more training modes and integrations:
- 🏋️ Training modes: Mi Band 5 offers 11 modes (running, cycling, swimming, etc.), while Mi Band 6 expanded the list to 30, including yoga, boxing, rope and even dancing).
- 📱 Notifications: The sixth model added support for quick responses to messages (for Android), as well as the ability to control music directly from the bracelet screen (in the Mi Band 5, this was only available through third-party firmware).
- 🔋 Power consumption: Despite the larger screen, the Mi Band 6 retains comparable autonomy thanks to the optimized Dialog chip DA14706. The fifth version was used in DA14695, which was less energy efficient.
- 🌍 Language support: Mi Band 6 officially supports Russian in the interface of the bracelet (in Mi Band 5 Russian was only in the application).
One of the most useful innovations in the Mi Band 6 is PAI, a personal activity index that measures your fitness based on your age, gender and intensity of exercise, and it provides recommendations for better health, which can be useful for new fitness users. There is no similar system in the Mi Band 5.
On the other hand, the Mi Band 5 had one advantage: a built-in magnetic charging cable that was harder to lose, and Xiaomi returned to the traditional charging connector in the sixth version, which caused some users to complain.
💡
To extend battery life in the Mi Band 6, turn off the Always-On Display feature and reduce the automatic heart rate to 10 minutes, which will increase battery life from 14 to 18-20 days.
5. Autonomy and charging: who holds the longer?
Official data from Xiaomi states that the Mi Band 5 lasts up to 14 days on a single charge, and the Mi Band 6 for up to 15 days.
| Mode of use | Mi Band 5 | Mi Band 6 |
|---|---|---|
| Basic (stepmer, time, notifications) | 18-20 days | 16-18 days |
| Average (heart rate every 30 minutes, SpO₂ 1 time per day) | 12-14 days | 10-12 days |
| Intensive (continuous monitoring of heart rate, GPS, exercise) | 5-7 days | 4-6 days |
| Full charge time. | ~1.5 hours | ~2 hours |
As you can see from the table, the Mi Band 6 is less than its predecessor in autonomy due to the more energy-intensive screen and additional sensors, but the difference is not critical: when used moderately, both bracelets require charging approximately once every 10-14 days.
An important difference is the charging method:
The Mi Band 5 uses a magnetic cable that attaches to the back of the body, which is convenient, but the cable itself is easy to lose.
The Mi Band 6 is back to the traditional connector (like the Mi Band 4), which makes it easier to replace the cable but makes the charging process less intuitive.
⚠️ Warning: If you use a swimming bracelet, dry the charging connector in the Mi Band 6 after contact with water. Moisture can lead to corrosion of contacts and charging problems. The Mi Band 5 does not have this problem due to the magnetic mounting.
6.Price and relevance in 2026
At the time of release in 2020-2021, the price difference between the models was about 1,000-1,500 rubles, but in 2026 the situation changed:
- 💰 Mi Band 5 can be found at a price of 1,500 to 2,200 rubles (depending on the equipment and the seller).This makes it one of the most budget options for basic fitness tracking.
- 💰 The Mi Band 6 costs between 2,000 and 2,800 rubles, but there are often promotions that reduce the price to the level of the fifth model. New bracelets (for example, Mi Band 7 or Mi Band 8) are already available, so the Mi Band 6 gradually goes off the shelves of official stores.
Should you overpay for the Mi Band 6 in 2026? The answer depends on your needs.
- ✅ Choose Mi Band 6 if you care about: - Large and informative screen. - Advanced exercise modes (30 vs. 11). - Stress monitoring and improved sleep analysis. - More accurate heart rate sensors and more accurate sleep analysis. SpO₂.
- ❌ Stop at Mi Band 5 if: - You want maximum autonomy. - You don't use advanced features (SpO₂, stress, PAI). - You want to save 500-1000 rubles without losing basic functionality.
If budget allows, consider the newer models, the Mi Band 7 or Mi Band 8, which offer an even bigger screen, improved GPS and additional sensors. However, if the choice is only between the fifth and sixth versions, the Mi Band 6 objectively offers more for the same money (including shares).
💡
In 2026, the Mi Band 6 remains the best choice in terms of price/function ratio, while the Mi Band 5 is suitable for those who are looking for the most budget option without bells and whistles.
