Why Notifications Are Coming to Xiaomi Mi Band 4: A Complete Diagnostic and Correction Guide

The Xiaomi Mi Band 4 fitness bracelet has long been one of the most popular wearables due to its combination of functionality and affordable price, but many users are faced with a common problem: notifications from the phone stop coming to the wristband screen — whether it is calls, SMS, messages from messengers or reminders from the calendar. In some cases, the problem is episodic, in others, notifications disappear completely, despite all attempts to return them.

The reasons for this behavior can be found in the settings of the bracelet itself, in the smartphone, in the Mi Fit application (or its alternatives like Zepp Life), as well as in the features of the Android or iOS operating system. In this article, we will analyze all possible scenarios from basic checks to deep diagnostics and offer working solutions for each case, paying special attention to the hidden energy saving settings in MIUI, which block the background operation of applications without notifying the user.

1. Check the basic settings of the Mi Band 4 and the Mi Fit app

Before you go into the technical details, make sure that the problem is not the basic settings, and users often accidentally turn off notifications or fail to complete the sync process.

Open the Mi Fit app (or Zepp Life if you use it) and follow the following steps:

• 🔹 Go to the Profile section → Xiaomi Mi Band 4 → Notifications.
• 🔹 Make sure the Allow Notifications slider is on (should be green).
• 🔹 Check the list of applications: next to each messenger (WhatsApp, Telegram, etc.) should be a checkbox.
• 🔹 Click Sync in the top right corner – sometimes changes don’t apply without manual sync.

If notifications are enabled but still don't come, move on to the next step. Please note that after updating the Mi Fit app, settings may be reset, a common cause of sudden disappearance of notifications.

2. Power saving settings on a smartphone: the hidden cause of problems

One of the most insidious reasons is the optimization of the battery in Android, which automatically limits the background work of applications, including Mi Fit. This is especially true for Xiaomi, Redmi or POCO smartphones based on MIUI, where energy saving works more aggressively than in pure Android.

To fix this:

1. Open Phone Settings → Applications → Application Management.
2. Find Mi Fit (or Zepp Life) and select it.
3. Go to Energy Saving → No restrictions.
4. Activate the "Out-Run" option (allows the application to run in the background).
5. Enable "Blocking in the background" (prohibits the system from killing the process).

For device owners on MIUI 12/13/14, add the app to the list of Special Permissions → Priority Applications.This ensures that the system will not limit it even when the battery is low.

Bluetooth problems: connection is there, but no notifications

The bracelet can be connected to your phone via Bluetooth, but the notifications still don't come.

• 🔄 Unstable connection (bracelet periodically disconnected and reconnected).
• 🔇 Bluetooth restrictions in Android settings (e.g., banning notifications).
• 📱 Conflict with other devices (if a headphone, column or other bracelet is connected to the phone).

How to diagnose and correct:

1. Reconnect the bracelet: In Mi Fit, go to Profile → Xiaomi Mi Band 4 → Disable the device. Turn off Bluetooth on your phone for 10 seconds, then turn it on again. Connect the bracelet again through the app.
2. Check Bluetooth permissions: Settings → Connected devices → Settings (cog next to Mi Band 4) → Permissions Make sure Notifications and Contacts are enabled (for calls).
3. Disable other Bluetooth devices: Sometimes a smartphone can’t maintain a stable connection to the bracelet and wireless headphones at the same time.

💡

If the bracelet plugs in but shuts down quickly, try resetting it to factory settings: press the touch button for 10 seconds until vibration appears.

4. Conflicts with the firmware of the bracelet and applications

Outdated or incorrectly installed firmware Mi Band 4 can cause notifications to crash, and problems arise after the Mi Fit app updates, when the new version conflicts with the old firmware bracelet.

How to check and update:

• 📲 Bracelet firmware: in Mi Fit go to Profile → Xiaomi Mi Band 4 → Update the firmware. If a new version is available, install it.
• 🔄 Reinstall Mi Fit: Remove the app, restart the phone and install it again from Google Play or App Store.
• 🛠️ Reset bracelet: If the update didn't help, reset the bracelet to factory settings (see spoiler below).

If after reset notifications earned, but then disappeared again – the problem is most likely in the conflict of firmware with your smartphone model, in this case, a rollback to the old version of Mi Fit (for example, 4.6.0 is one of the most stable).

5. Features of working with different versions of Android and iOS

The notification behavior may vary depending on the phone’s operating system.

For the iPhone, also check:

• 🔒 Notification permissions: Settings → Notifications → Mi Fit → Allow notices.
• 🔄 Background Update: Settings → Mainstream → Content updates → Mi Fit (insert).

💡

On iPhone, notifications from some messengers (like WhatsApp) may not arrive on Mi Band 4 due to Apple restrictions.

6. Hardware problems: when the bracelet itself is to blame

If all software methods have been tried, but notifications still don’t arrive, hardware malfunctions are possible:

• 🔋 Weak battery: When under 20%, the bracelet can turn off "non-critical" features, including notifications.
• 📡 Bad Bluetooth Module: If the connection is constantly breaking, the antenna may be damaged.
• 💧 Moisture: Even after drying, the contacts could oxidize.

How to diagnose:

1. Check if the charging indicator is on when connecting to USB. If not, there is a problem with the battery or power controller.
2. Connect the bracelet to another phone. If the notifications work, it's your smartphone's fault; if it doesn't, it's your bracelet.
3. Look at the corrosion under the charger contact lid, and white plaque or green spots are a sign of oxidation.

⚠️ Warning: If the bracelet fell from a height or was subjected to severe blows, the plume of the display or Bluetooth module could move away, in which case only repairs at the service center will help.

7. Alternative notification annexes

If the standard Mi Fit app is stubbornly reluctant to work with notifications, try third-party solutions. They often bypass the limitations of MIUI and offer more flexibility in settings.

Top.-3 alternatives:

• 🔹 Notify & Fitness for Mi Band – supports all Mi Band models, allows you to adjust vibration and notification filters.
• 🔹 Mi Band Master – Advanced settings, including the selection of notification apps.
• 🔹 Tools & Mi Band – works even on outdated firmware.

How to switch to an alternative application:

1. Remove Mi Fit (not necessarily, but recommended to avoid conflict).
2. Install one of the listed apps from Google Play.
3. Connect the bracelet through the new app and set up notifications manually.

⚠️ Note: Third-party apps may require more permissions than Mi Fit. SMS Check the security reviews before installing.
