In this guide, we'll take a look at not only the standard settings, but also the hidden chips that the manufacturer doesn't always advertise, how to properly sync the bracelet to your phone, set up spam-free notifications, use training modes to maximize efficiency, and extend battery life. We'll focus on the accuracy of the data — why the bracelet can lie and how to fix it.
If you’ve just unpacked Mi Band 5 or have been using it for a long time but want to unleash its potential to 100%, this is the guide for you. All steps are illustrated with current screenshots from the Mi Fit app (version 4.6.0) and tested on the firmware of the bracelet 1.0.9.54.
1. First Enablement and Basic Setup of Mi Band 5
Before first use, the bracelet must be charged — even if the indicator shows residual charge. Connect the device to the charging cable (included) and wait for full charge (about 2 hours). Do not use charges from other devices — this can damage the battery. The indicator on the bracelet screen will show the charging process: from the flashing icon of the battery to the full filling of the scale.
After charging:
- 📱 Install the Mi Fit app (Android/iOS) Sign up (or sign in via your Xiaomi, Google, Facebook account).
- 🔗 Turn on Bluetooth on your smartphone and allow the app to access geodata (necessary for accurate activity tracking).
- 🔍 In the app, click Profile → Add the device → Bracelet → Mi Smart Band 5.
- 📶 Wait for the bracelet to appear in the list and confirm pairing on both devices.
If the bracelet is not present, check:
- 🔋 Charge level (should be) ≥20%).

- 🔄 Reboot Bluetooth on your smartphone (Settings) → Bluetooth → Off./On.).
💡
If the bracelet doesn’t sync, try resetting it to factory settings: press the touch button for 10 seconds until the vibration and Mi logo appear.
After a successful connection, the application will offer to update the firmware of the bracelet. It is not recommended to refuse updates - in new versions, sensor errors are corrected and support for new functions is added (for example, monitoring). SpO₂ appeared in firmware 1.0.8.20). The process will take 5-10 minutes, do not interrupt the connection.
2.Setting up notifications: how to filter out spam
By default, the Mi Band 5 shows notifications from all apps, which quickly drains the battery and clogs the screen with unnecessary information.
- Open Mi Fit. → Choose a bracelet → Notifications of annexes.
- Activate the Display Notifications switch.
- In the list of applications, leave ticks only for important ones (for example, Phone, Messages, WhatsApp, Calendar).
- For each application, set up Vibration and Screenlighting (useful for nighttime notifications).
Hidden notification settings:
- 📵 To completely disable notifications for sleep, activate Do Not Disturb Mode in the bracelet menu (Settings) → Don't disturb).
- 🔕 For important contacts, you can adjust the individual vibration: in Mi Fit go to Contacts → Add and select a unique pattern.
- 📧 To ensure that notifications are displayed in full (not just the title), turn on Show Content in the bracelet settings.
If notifications are late (or not coming at all), check:
- 🔄 In your phone settings, turn off Battery Optimization for the Mi Fit app (on Android: Settings) → Annexes → Mi Fit → Battery → No restrictions).
- 📱 On iPhone, allow Mi Fit to work in the background (Settings) → Mi Fit → Background update).
- 🔗 Reconnect the bracelet (forget the device in Bluetooth settings and mate again).
3. Activity tracking: pedometer, exercise and calories
The Mi Band 5 automatically captures steps, distance and calories burned, but the accuracy of the data depends on the correct settings.
- In Mi Fit go to Profile → Settings → Length of step.
- Specify your height – the app will calculate the average step length (or enter it manually after a test walk).
- For accurate calorie count, specify weight in the Profile section → Personal data.
The training regimens are activated directly from the bracelet:
- 🏃♂️ Running (outside / track) - records the pace, pulse and trajectory (when connected GPS phone).
- 🚴♂️ Bicycle – tracks the speed and calorie consumption (attach the bracelet to your hand, not the steering wheel, for accuracy!).
- 🏊♂️ Swimming – works in the pool (specify the length of the track in the settings).
- 🧘♀️ Yoga/Stretching – monitors pulse and activity time.
Charge the bracelet (≥50%)|Turn on GPS on the phone (for running/bicycle)|Choose the right training regimen|Fix the bracelet tightly (2 fingers above the wrist)|Set up autopause in Mi Fit (Settings) → Training)
-->
To ensure that the data is as accurate as possible:
- 📏 Wear the bracelet on the non-dominant hand (for right-handed - left, for left-handed - right-handed).
- 💦 When sweating or rain, wipe the sensors - moisture distorts the pulse indicators.
- 📱 Take your phone with you for running/bicycle – the bracelet uses it GPS route-line.
Why does the bracelet lower your steps?
| Type of activity | Accuracy of data | Improvement tips |
|---|---|---|
| Walking | 90-95% | Wear the bracelet tightly, calibrate the length of the stride |
| Run. | 85-90% | Turn it on. GPS On the phone, avoid sudden movements of the hand. |
| Cycling | 80-85% | Put the bracelet on your hand, not on the steering wheel. |
| Swimming | 75-80% | Specify the length of the pool, avoid sharp swings |
| Son | 70-85% | Wear a bracelet on a non-dominant hand, turn off alarm clocks |
4. Monitoring sleep and stress levels: how to read data
Mi Band 5 analyzes sleep by phase: deep, light and REM (rapid eye movement phase for accurate tracking:
- 😴 Wear a bracelet every night (data is accumulated and updated for the duration of the day). 7-14 days).
- ⏰ Go to bed at the same time – algorithms better recognize cycles.
- 📵 Activate the Do Not Disturb mode (so that vibrations do not wake up).
Transcription of sleep indicators in Mi Fit:
- 🌙 Deep sleep (20-25% Recovery time. - Normal: 1.5-2 hour.
- 🌓 Light sleep (50-60%) — Long periods may indicate restless sleep.
- 👁️ REM-sleep (20-25%) — It's important for memory and emotion: 4-5 night-cycle.
- ⚠️ Awakenings (>5 times) – a signal of poor sleep quality (possible causes: noise, temperature, apnea).
The stress measurement function works based on heart rate variability (HRV). Indicators in Mi Fit:
- 😊 1-39 — low-stress.
- 😐 40-59 — Moderate (a short break is recommended).
- 😨 60-100 — High (needs relaxation or sleep).
💡
If the bracelet shows high levels of stress during the day, try breathing exercises: select Stress from the bracelet menu → Breathing and following the instructions on the screen (5 minutes of deep breathing normalizes the pulse).
To improve monitoring accuracy:
- 🕒 Wear a bracelet for at least 20 hours a day (workout/retirement misrepresents data).
- 🚿 Remove the device only under the shower or for charging.
- 📊 Compare data with other devices (such as a smartphone) in the first 2 weeks to help identify system errors.
Measurement of pulse and SpO₂: when and how to use
The pulse sensor on the Mi Band 5 works on the principle of photoplethysmography (PPG) — It shines with green LEDs and analyzes the reflected light:
- 🧘 Sit down and relax 5 minutes before measurement.
- 💡 Hold the bracelet tightly (but don’t hold your hand tightly).
- 📵 Avoid movement during measurement (even small tremors).
To measure your pulse:
- On the bracelet, go to the Pulse menu.
- Wait for the indicators to stabilize (10-15 seconds).
- For continuous monitoring, enable settings in Mi Fit → Monitoring of heart rate → Continuously (discharges the battery on the 20-30% faster).
Function SpO₂ (The blood oxygen saturation was in firmware 1.0.8.20:
- 🟢 95-100% — level-of-play.
- 🟡 90-94% — mild hypoxia (possible with physical exertion or in the mountains).
- 🔴 <90% — Critical condition (a doctor’s consultation is required).
💡
If SpO₂ constantly <95%, Check the bracelet's mounting density - the sensor's weak contact with the skin distorts the results. Also avoid measurements with cold hands (vasoconstrictor effect).
The limitations of the Mi Band 5 sensors:
- ❌ Does not replace medical equipment (pulse error) ±5 punches, SpO₂ ±2%).
- ❌ Does not work with tattoos/scars on the wrist (LEDs do not penetrate the pigment).
- ❌ Indicators may be inaccurate with arrhythmia or fibrillation tachycardia.
