Xiaomi Mi Band 7: a full review of new products and differences from the Mi Band 6

The Xiaomi Mi Band 7 is a logical extension of the budget fitness bracelet line, but with significant improvements that many users have been waiting for years. Launched in June 2022, the gadget retained its familiar minimalist design, but received a brighter display, enhanced health monitoring capabilities and improved autonomy. If you are wondering whether to upgrade with the Mi Band 6 or buy your first fitness tracker, this review will help make a decision.

In this article, we will take a look at all the key innovations of the seventh version, compare it with its predecessor and answer the questions that users often have, focus on practical aspects: how the changes affect everyday use, which features are really useful and which are only a marketing ploy, and you will find tips for setting up and optimizing the bracelet.

Display: bigger, brighter, faster

The most notable change in the Mi Band 7 — it 1,62-inch AMOLED-resolution-screen 192×490 For comparison, the Mi Band has pixels. 6 diagonal 1,56 quintuple 152×486 It's a little bit different, but in practice, it looks much bigger and sharper. 25%, This allowed you to put more information on the main screen without having to flip through.

Another important improvement is brightness up to 450 nits (versus 400 nits in its predecessor), which now reads well even in direct sunlight, and thanks to Always-On Display (AOD), you can adjust the display of time and basic metrics (pulse, steps) without having to raise your hand or press a button.

• 📱 Screen size: 1.62" (vs 1.56" in Mi Band 6)
• 🔦 Maximum brightness: 450 nits (vs 400 nits)
• 🎨 Color gamut: 16.7 million shades (unchanged)
• ⚡ Update frequency: up to 60 Hz (smooth animation)

Also in Mi Band 7, there are more than 100 new dials, including animated and themed ones (such as those with characters from Star Wars or Marvel), which can be downloaded directly from the app. GIF-animations on the lock screen is a trifle, but pleasant for fans of customization.

Sensors and Health Monitoring: What Really Works?

The Xiaomi Mi Band 7 has an updated optical heart rate sensor (PPG) with improved measurement accuracy, now able to detect arrhythmia (including fibrillation) and alert the user to possible violations. It is important to understand that the bracelet does not replace medical equipment, but can be an occasion for a visit to the doctor if regularly detects failures.

Another key innovation is monitoring blood oxygen levels (SpO₂) The Mi Band 6 had this feature, but it only worked on demand, and now the bracelet automatically tracks saturation and warns if it falls below normal (usually 90%). This is especially useful for those who suffer from apnea or other sleep disorders.

• ❤️ Heart Rate Frequency: Continuous Monitoring + phthalmia
• 😴 SpO₂: automatic measurement during sleep
• 🏃 Stepmer: an improved algorithm for filtering false steps
• 💤 Sleep: phase analysis (REM, light, deep) + nap

In terms of sleep tracking, the Mi Band 7 has learned to recognize daytime naps (if you take 20-30 minutes of naps) and more accurately identify phases. REM-However, the accuracy depends on the correct setting: if you go to bed at the wrong time as specified in the application, the data may be distorted.

💡

To improve the accuracy of sleep monitoring, manually specify the time of going to bed and waking up in the Mi Fitness app. The bracelet algorithms will take this interval into account for analysis.

Autonomy: Does the battery hold longer?

Xiaomi officially claims that the Mi Band 7 lasts up to 15 days on a single charge, in standard use, and in practice, this ranges from 7 to 12 days, depending on the activity of the functions. By comparison, the Mi Band 6 lasted 5 to 9 days on average.

1. Optimized processor (more energy efficient than the previous model).
2. Improved screen control algorithm (e.g., Always-On Display can be turned off for savings).
3. More capacious battery - 180 mAh (versus 125 mAh in the Mi Band 6).

However, there are nuances: if you actively use Always-On Display, continuous monitoring is possible. SpO₂ And the notifications, the bracelet will discharge in 4-5 days:

Turn off Always-On Display|Reduce the screen brightness to 50%|Disable continuous monitoring SpO₂|Turn off notifications from unnecessary applications-->

Charging is done through a magnetic connector that comes with the complete cycle, which takes about 2 hours — longer than the Mi Band 6 (there were 1.5 hours), but this is due to the increased battery capacity.

Fitness functions: 120 modes of training and not only

Mi Band 7 supports 120 training regimes (vs. 30 for Mi Band 6), including exotic types like yoga. SUP-In practice, most users use no more than 10-15 modes, but the expansion of the list indicates Xiaomi’s desire to reach the maximum audience:

• 🏊 Swimming: automatic style recognition (brass, crawl, butterfly) and stroke counting.
• 🚴 Cycling: Integration with external speed/cadence sensors (via Bluetooth).
• 🧘 Yoga and stretching: detailed statistics on time in poses.
• 🏋️ Strength training: recognition of exercises (squats, push-ups, pull-ups).

Important clarification: automatic exercise recognition doesn't work perfectly, for example, the bracelet may confuse walking with running or not record short intervals of activity, and for accurate accounting, it's better to choose a manual mode before exercising.

Another useful feature is the post-workout recovery score, which is analyzing heart rate, heart rate variability (HRV) and stress levels to advise when to exercise again, and this is relevant for those who are monitoring overexertion and want to avoid injury.

Smart Features: Notifications, Payments, and Voice Assistant

The Mi Band 7 has retained all the smart features of its predecessor and added a few new ones.

• 📱 Show notifications from messengers and social networks (with support for emoji).
• 💳 Pay for purchases through Mi Pay (works only with partner banks, in Russia is irrelevant).
• 🎤 Manage a voice assistant (such as Alice or Google Assistant on a smartphone).
• 🔍 Search for phone (bracelet vibrates if smartphone is within range of Bluetooth).

The most controversial innovation is voice assistant support, and in practice, it works like this: you press the bracelet screen, say a command (e.g., "Set the alarm at 7:00"), and it's transmitted to your smartphone for execution. Convenient, but only if you always have Bluetooth on and the microphone on your phone, otherwise the function is useless.

As for notifications, they now display fully text messages (up to 100 characters) and emojis. Mi Band 6 often cut long messages, and here the problem is solved. However, you can't respond to messages from the bracelet - just read and delete.

💡

The main limitation of smart functions is smartphone dependence. Without a Bluetooth connection, most features (notifications, payments, voice assistant) will not work.

Design and Ergonomics: What Has Changed?

The Mi Band 7 looks almost identical to the Mi Band 6, with the same rectangular body with rounded corners and a removable silicone strap, but there are some important improvements:

• 🔄 Quick removable mechanism - now the strap changes in seconds without tools.
• 🛡️ Water Protection Standard 5 ATM (You can swim at a depth of 50 meters).
• 🎨 More strap options - including fabric and metal (sold separately).

The weight of the bracelet is still the same, at 13 grams (without the strap), so it's almost not felt on the arm. But the sensor is now stronger, which is why some users complain about discomfort when wearing it while sleeping. If you sleep on the side with the bracelet, you may have to get used to it or wear it looser.

Color options: black, white, green, orange, blue. straps come in the kit depending on the version (for example, in the box). NFC-The version may be a different set of).

💡

If the bracelet rubs the skin, try to wear it 1-2 cm above the wrist or use a hypoallergenic strap made of soft silicone.

Mi Band 6 Comparison: Should I Upgrade?

If you already have the Mi Band 6, should you upgrade to the seventh version? The answer depends on what features are critical to you:

It is worth updating if:

• You need a Always-On display or a brighter screen.
• You are actively monitoring your health (SpO₂, arrhythmia, sleep).
• You didn’t have the autonomy of the Mi Band 6.
• You play different sports and want detailed statistics.

It is not necessary to update if:

• You only use the bracelet for pedometers and notifications.
• The price difference is significant for you (the new model is often bought at least 4000-4500). ₽).
• Your Mi Band 6 is completely fine.

💡

If your Mi Band 6 is working properly and you don't need new features, there's no point in upgrading. The difference between the models is noticeable, but not critical for most users.
