Why Xiaomi bracelet does not vibrate when calling: solutions

The situation when Xiaomi’s smart bracelet stops vibrating at the most inappropriate moment is familiar to many wearable electronics owners: You wait for an important call or notification, but the wrist is silent, and missed calls accumulate. This can happen suddenly after an application update, or routinely when the device simply stops responding to incoming signals. Synchronization failure is one of the most common, but not the only cause of this problem.

In most cases, it's not a physical malfunction of the vibrator, but rather a software conflict or power saving setting. The operating systems of modern smartphones, whether Android or iOS, aggressively optimize background processes, which often leads to a disconnection of communication with the gadget. You do not need to be an engineer to fix this, because the algorithms of actions are quite simple and logical.

In this article, we will look at all the possible reasons for your tracker’s silence and offer step-by-step instructions for restoring functionality. We will touch on the settings of the Mi Fitness or Zepp Life application itself, check system permissions and discuss the nuances of Bluetooth connection. In 80% of cases, the problem is solved by re-authorizing the device in the application without completely resetting. Let’s start by checking the basic parameters.

Checking the main notification settings

The first thing you need to do is make sure that the vibration function is activated in the software at all. Often users accidentally turn off notifications for specific applications or calls in general. Go to the application through which you control the bracelet, and find the Profile → Device Settings → Notifications section. Here the switch responsible for incoming calls should be activated.

Note that settings may vary depending on your tracker model. For the Mi Band 6, 7, 8 and older versions, the interface may look different, but the logic remains the same. If the slider is on, try turning it off, saving the changes and turning it on again. This action will restart the notification service on the gadget side.

⚠️ Warning: Make sure the bracelet itself is in "Do Not Disturb" mode" (DND). If this mode is active, the device will ignore all incoming signals, even if the phone is a loud ringtone.

It's also worth checking if the bracelet has a "Sleep" or "Silent Mode" mode, which in some firmwares take precedence over regular notifications, and if you see a moon icon or a bell on the tracker screen with a bell crossed out, then the vibration is locked software at the device level.

Configuring permissions in Android and iOS

The smartphone’s operating system takes precedence over apps, and if you have denied Mi Fitness or Zepp Life access to notifications, the bracelet will not receive a call signal. On modern versions of Android (10, 11, 12, 13, 14), you must manually allow access to the call log and notifications. Go to Settings → Applications → Mi Fitness (or Zepp Life) → Permissions.

It is critical to enable access to contacts, phone and SMS. Without permission to access the phone, the app will not physically know about the incoming call. Also, in the Notifications menu inside the app settings, make sure that the "Allow Notifications" tick is ticked and the display on the lock screen is selected.

For iPhone owners, the situation is a little different, since iOS has stricter background rules: You need to go to Settings → Bluetooth, find your bracelet in the list of devices, click on icon (i) and turn on the Toggle “Show Notifications”.

• 📱 Android: Allow access to contacts and phone in the app system settings.
• 🍏 iOS: Enable notifications in Bluetooth settings for a particular device.
• 🔔 General: Check if the pop-up ban is worth it for a companion app.
• 🔋 Energy: Make sure the system is allowed to run the application in the background.

Remember that after updating the smartphone operating system, some resolutions may be reset to default values. So if the problem appears immediately after the phone update, check this section first.

Problems with energy saving and background work

Aggressive energy saving algorithms are the main enemy of the stable operation of smart wristbands. The system can “sleep” the Mi Fitness application, considering it inactive, which leads to a disconnection and no vibration. To avoid this, you need to add the application to the exceptions or whitelist.

On Xiaomi smartphones (MIUI/HyperOS), this is done through the Battery and Performance menu. Find the app in the list, click on it and select "No restrictions." Also, be sure to stick the app in memory: open the list of running apps, find Mi Fitness and pull it down to get a lock.

For other brands, such as Samsung, Huawei or Honor, menu names may differ, but the bottom line is that you should prevent the system from killing the application process.

⚠️ Note: If you use third-party memory cleaners or antiviruses, they can also block the bracelet.Add a companion app to your antivirus exceptions.

It is important to understand that background work is necessary for constant monitoring of the Bluetooth connection. If the application is closed, the bracelet will go into standby mode and will check the connection only periodically, which may cause you to miss the moment of the call.

Resetting and reconnecting the device

If the software settings are fine but the vibrations are still gone, a complete reset will help, which eliminates protocol errors that may have accumulated during use. Don't worry, your steps and sleep data will be stored in the cloud or in your phone's memory.

First, remove the device from the app: go to profile, select your bracelet, and click Untie or Delete the device. After that, it is advisable to remove the app from the Bluetooth list in the phone settings to erase the old pairing keys.

Once you've done these steps, re-find the bracelet through the app, and when you pair it, you may have confirmation codes on your phone and bracelet screen -- make sure they match. Once you've successfully connected, the test call should cause a vibration.

Update of firmware and applications

Outdated software is a common cause of unstable work. Developers regularly release patches that fix notification bugs and Bluetooth stack. Check the firmware version in the app: Profile → Add the device (or bracelet selected) → Check for updates.

Also make sure that the Mi Fitness or Zepp Life app itself is updated to the latest version on Google Play or the App Store.Old versions may not work properly with newer versions of smartphone operating systems, especially after major Android updates.

The firmware update process requires a stable connection: Put your phone and bracelet next to you, make sure the tracker battery is above 20%, and don’t interrupt the process or open other heavy applications while downloading data.

💡

Before updating the firmware, be sure to clear the app cache in the phone settings, which will reduce the risk of errors when writing new data to the device.

Hardware malfunctions and diagnostics

If all software methods are exhausted and the bracelet is silent, perhaps the problem lies in the hardware. A vibromotor is a mechanical element that can wear out or fail over time due to impacts or moisture.

Do a simple test: find the "Find Phone" or "Vibration Test" function in the wristband menu (if available in your model), if the bracelet vibrates when activated, then the motor is functional, and the problem is exactly in the software part or compatibility. If there is no reaction, there is a high probability of a hardware defect.

• 💧 Moisture: Sweat or water may have oxidized the vibrator contacts.
• 🔨 Impact: Mechanical damage could have shifted the eccentricity of the motor.
• 🔋 Battery: Critically low charge or battery wear may not produce enough current to vibrate.
• 🔌 Contacts: Oxidation of charging contacts can affect the overall operation of the system.

⚠️ Warning: Don't try to disassemble the bracelet yourself. Xiaomi Mi Band cases are usually glued, and the opening is guaranteed to violate moisture protection, and to collect them back tightly at home is almost impossible.

In the event of a hardware malfunction, the most sensible solution would be to go to the service center or replace the device if the warranty has already expired.

💡

If the test vibration in the wristband menu works, then Hardware is serviceable, and the problem should be looked for in the settings of the smartphone and application.
