Xiaomi Mi Band 4 remains one of the most popular fitness bracelets even years after its release - and for good reason. Compact design, 20-day autonomy, color AMOLED-The screen and precise sensors make it an ideal assistant for sports and everyday health monitoring. However, many users use only 30% of the device’s capabilities, unaware of the hidden settings that turn a simple pedometer into a full-fledged sleep, pulse and even a swimming assistant tracker.
In this article, you’ll find step-by-step instructions for setting up the Mi Band 4 from scratch, from first turning on and pairing with your smartphone to finely calibrating notifications, training modes and energy saving. We’ll reveal unique firmware chips 1.0.7.14 (the last stable for the Mi Band 4) that are missing from the official documentation, and show you how to get around typical sync errors with Mi Fit and Zepp Life. If your bracelet suddenly discharges in a day or doesn’t show notifications, here you’ll find a solution.
1.Preparation for the first inclusion: what to do before setting up
Before you start setting up Mi Band 4, make sure you have everything you need. Many users face sync problems due to trivial mismatches or lack of access rights. Here is a checklist for a seamless start:
Smartphone on Android 6.0+ or iOS 10.0+| Official Mi Fit app (version 4.6.0+) or Zepp Life| Charged bracelet (minimum 20% battery)|Enabled Bluetooth 4.0 LE on phone |Resolve notifications for Mi Fit-->
If your Mi Band 4 has been purchased for a long time and has never been updated, you may be at risk of encountering an “infinite sync” bug when connecting to new Mi Fit versions.
- Remove the Mi Fit app and install version 4.6.0 (download from APKCombo).
- Update the bracelet firmware to 1.0.7.14 via the Device Profile menu → Software Update.
- Only then update Mi Fit to the current version.
💡
If the bracelet doesn’t turn on after a long storage period, plug it into a 30-40-minute charge, and even the fully discharged Mi Band 4 battery starts showing signs of life after 20 to 30 minutes of USB connection.
2.Paraliament with the phone: step-by-step instructions without errors
The process of connecting the Mi Band 4 to a smartphone seems simple, but there are pitfalls here. For example, if you use an iPhone, binding to a Xiaomi account is mandatory — without it, the bracelet will not sync data. On Android, this step can be skipped, but then you lose access to the cloud backup of settings.
Follow the algorithm:
- Turn on the bracelet with a long press on the touch button (3-5 seconds). The Mi logo will appear on the screen.
- Open Mi Fit or Zepp Life and go to Profile → Add Device → Bracelet → Mi Smart Band 4.
- Press "Hide" and confirm the action on the bracelet (short touch on the screen).
- Select your bracelet from the list of detected devices (the name will be in Mi Band XX:XX format).
- Confirm the binding to the Xiaomi account (required for iOS, optional for Android).
What if the bracelet is not on the list of devices?
Critical error: If the bracelet is permanently turned off after pairing, check the phone's power saving settings. On Xiaomi/Redmi, add Mi Fit to auto-cleaning exceptions (Settings → Battery → Application Selection → Mi Fit → Without restrictions). On Samsung, turn off optimization for the app in the device care menu → Battery → Background work.
3. Basic settings: time, notifications and screen
After successful connection, first of all, set up the main parameters on which the usability depends:
- 🕒 Time and date: sync automatically when you first connect. If the clock is stray, check your phone's time zone settings.
- 🔔 Notifications: Enable the option in Mi Fit → Mi Smart Band 4 → Call and message notifications: Select the apps you want to see notifications from (e.g. WhatsApp, Telegram, Gmail).
- 📱 Screen: in the menu, adjust the display and brightness: Autoturn screen (good for left-handers); Brightness (recommended 3-4 divisions for the balance of visibility and autonomy); Backlight time (optimum - 5 seconds).
Hidden feature: If you are disturbed by accidental touching of the screen while sleeping or exercising, activate the screen lock in the bracelet settings (Mi Fit → Mi Smart Band 4 → Other settings → Screen lock).
Calls only | Calls + messages | All notifications | I don't show anything-->
| Parameter | Recommended value | Why is it important? |
|---|---|---|
| Screen brightness | 3-4 division | Balance between sun visibility and battery consumption |
| Lighting time. | 5 seconds | Enough to read notifications, but doesn't discharge the bracelet |
| Auto-raising of the hand | Included. | The screen lights up when you move your hand – convenient for checking the time |
