Fitness bracelets Xiaomi Mi Band has long been the benchmark for the ratio of price and functionality in the market of wearable electronics. With the release of each new version, users are wondering: should I upgrade? This question was especially acute when moving from the fifth to the sixth generation – the changes were so significant that many owners of the Mi Band 5 thought about buying a new model.
In this article, we’ve done a deep analysis of the differences between the Mi Band 5 and the Mi Band 6, based not only on the official specifications, but also on real-world experience. You’ll learn what innovations came out of the sixth version, what features were removed, and most importantly, how justified the price difference between the models in 2026.
If you're faced with a choice between these two bracelets, or just want to understand what the new version does, this material will help you make an informed decision, and for Mi Band 5 owners, we've prepared a checklist that will show you whether you should upgrade right now.
1. Design and Ergonomics: What has changed on the outside?
At first glance, the Mi Band 5 and Mi Band 6 look almost identical – the same minimalistic polycarbonate body with a touch button, the same interchangeable straps with a width of 18 mm.
The main new thing in the Mi Band 6 — If the five had a diagonal screen, 1.1 inch (24×12 Oh, and the six of them have grown to 1.56 inch (48×22 That's on. 40% More space, resolution has improved: 152×486 pixel-versus-pixel 126×294. And as a result, the text became clearer and the icons became larger, and this was especially appreciated by users with visual problems.
- 📏 Screen size: 1.1" (Mi Band 5) vs 1.56" (Mi Band 6)
- 🔍 Permission: 126×294 vs 152×486 pixel
- 🎨 Brightness: Up to 450 nits in both models, but an automatic regulator has been added to the Mi Band 6
- 🔄 Touch button: Mi Band 6 has become more responsive due to the new coverage
Another important improvement is the new straps, which come with the Mi Band 6, a silicone strap with an antibacterial coating that reduces skin irritation when worn for long periods of time, and the five lacked the coating, which sometimes caused discomfort for users with sensitive skin.
⚠️ Note: Despite the same width of the straps (18 mm), the mounts on the Mi Band 5 and 6 are different!
2. Autonomy: Who keeps the charge longer?
The official battery data for both models are almost identical: 125 mAh for the Mi Band 5 and 125 mAh for the Mi Band 6. However, in practice, the operating time is different – and here’s why.
The Mi Band 6 features a more energy-intensive processor (Apollo 3.5 vs Apollo 3 in the top five) and a larger screen, which should theoretically reduce autonomy. But Xiaomi engineers have optimized firmware: In the sixth version, the bracelet automatically reduces the frequency of sensors in sleep mode, saving up to 15% of charge.
| Parameter | Mi Band 5 | Mi Band 6 |
|---|---|---|
| Battery capacity | 125 mAh | 125 mAh |
| Autonomy (real) | 10-12 days | 12-14 days |
| Charging time. | ~1.5 hours | ~2 hours |
| Type of charging | Magnetic dock | Magnetic Dock (Enhanced Contacts) |
Fun fact: the Mi Band 6 has added an ultra-low power mode that shuts down all functions except pedometer and time. In this mode, the bracelet can last up to 19 days! The five do not.
⚠️ Note: If you are using the Mi Band 6 with constant monitoring SpO₂ (It's oxygenated, and you can get a little bit less autonomy for 7 to 9 days, and you can't get that function in the Mi Band 5, so you can run down the battery more slowly.
Sensors and Health Monitoring: Revolution or Marketing?
The differences between the models are the most significant, with the Mi Band 6 getting a completely updated sensor suite, allowing for new monitoring features.
The main innovation is the sensor SpO₂ (A pulse oximeter to measure blood oxygenation, and in the face of a pandemic and growing interest in lung health, this function became a key function, five could only measure heart rate, and six could also analyze heart rate. SpO₂, Sleep breathing and stress levels.
- ❤️ Heart rate: Continuous monitoring is added to the Mi Band 6 (every 1-2 minutes vs every 5-10 minutes in the Mi Band 5)
- 😴 Sleep: in the six appeared phase analysis REM-Sleep (Rapid Sleep) That Wasn't in the Five
- 🌡️ SpO₂: Only in Mi Band 6, it measures oxygen saturation in 30 seconds.
- 🧘 Stress: A new metric in Mi Band 6, which assesses stress levels by heart rate variability
Another important improvement is the pedometer accuracy: the Mi Band 6 used a new 6-axis accelerometer (vs 3-axis in the top five), which reduced the number of false positives, and now the bracelet better distinguishes walking from traveling in transport.

Sporting Features: What Activities Are Supported?
Both models are positioned as fitness trackers, but the Mi Band 6 received an expanded list of sports modes. If the five supported 11 activities, then the six already 30, including exotic ones such as Zumba, Pilates and street workouts.
Key improvements:
- 🏃 Automatic recognition: Mi Band 6 itself determines the beginning of running, walking or swimming (in the top five it worked worse)
- 🏊 Swimming: Open water support (not just swimming pool) added to six)
- 🚴 Cycling: there is a separate mode for mountain bike taking into account the differences in altitude
- 📊 Analytics: Mi Band 6 added metrics VO₂ max (maximum oxygen consumption) and recovery time
Some users have noted that the GLONASS in the Mi Band 6 is less stable than the GPS in the top five, especially in urban areas with tall buildings. If the exact geolocation is critical for you (for example, for marathon runners), this is worth considering.
💡
For more accurate distance tracking in Mi Band 6, turn off the energy-saving GPS mode in the Mi Fitness app settings, which will increase battery consumption but improve accuracy by 15-20%.
5. Software and compatibility
Both models work with the Mi Fitness app (formerly Mi Fit), but the Mi Band 6 has a number of exclusive features:
First, there are widgets on the screen. In the six you can add up to 5 widgets (weather, calendar, music, etc.), whereas in the five there were only 3.
The important difference is iOS compatibility. iPhone owners often complain that the Mi Band 5 doesn’t sync well with Apple Health, and notifications come with a delay. In Mi Band 6, these problems partially solved: synchronization has become faster, but background updates are still unstable.
| Function | Mi Band 5 | Mi Band 6 |
|---|---|---|
| Number of widgets | 3 | 5 |
| Animated dials | ❌ No. | ✅ Yes. |
| Voice assistant | ❌ No. | ✅ Yes, for Android only) |
| Synchronization with Apple Health | ⚠️ Partially. | ✅ Improved. |
Another innovation in the six is the voice assistant (so far only for Android), which is simple commands like "Set an alarm for 7:00" or "Show the weather." It works through the microphone in the bracelet, but voice recognition leaves much to be desired in noisy environments.
Make sure your smartphone runs on Android 6.0+/iOS 10.0+

6.Price and relevance in 2026: is it worth overpaying?
When the Mi Band 6 was released, it was 30 to 40 percent more expensive than the five, but today the difference has narrowed. In 2026, the Mi Band 5 can be found for 1,500 to 2,000. ₽, a Mi Band 6 for 2,200–2,800 ₽. Question: Is the difference justified?
If you need it:
- ✅ Large screen with better readability
- ✅ Monitoring SpO₂ stress
- ✅ Extended sports modes (30 vs 11)
- ✅ Analysis REM-sleep
The Mi Band 6 is worth the money, but if you have enough basic activity tracking, notifications and sleep monitoring without bells and whistles, the Mi Band 5 is still a great choice.
An important nuance: Xiaomi has already released the Mi Band 7 and Mi Band 8, so the Mi Band 6 can often be found on the stock cheaper than the Mi Band 5 in some stores.
💡
V 2026 Mi Band 6 It is more profitable to buy only on the stock or if the price difference with the Mi Band 5 less 500 ₽. In other cases, it is better to consider the Mi Band. 7/8 or wait for discounts.
7.Typical problems and complaints of users
No model is perfect. The Mi Band 5 users complain most often:
- 🔋 Fast battery discharge when used actively GPS
- 📱 Unstable synchronization with iPhone
- 💦 Moisture falling under the body during the voyage (despite the stated 5) ATM)
Mi Band 6 has other diseases.
- 📡 Poor quality GPS-tracking
- 🔄 Hanging when viewing notifications (reset by rebooting)
- 🎨 Some animated dials strongly plant the battery
A common problem for both models is the quality of the straps, and silicone stretches and cracks over time, especially if you wear the bracelet around the clock, and the solution is to buy spare straps from third-party manufacturers (like thermoplastic polyurethane).
⚠️ Warning: If you notice that the bracelet has started to count steps or heart rate incorrectly, try resetting to factory settings via the Settings menu → Additionally. → Reset: 60 percent of the time, it solves the problem without going to the service.
