Owners of fitness bracelets and smartwatches from Xiaomi and Huami often face the same trouble: the tracker stops syncing with the phone, and the data on the steps or pulse is lost. The reason for this phenomenon is an aggressive system of energy saving the shell MIUI or HyperOS, which forcibly closes the background processes to save battery power. To solve this problem, you need to fix the Mi Fit application (or its current counterpart) in the memory of the device, preventing the system from cleaning it.
The setup procedure does not require root rights or complex technical manipulations. All the necessary tools are already built into the operating system of your smartphone. However, hidden menus and specific settings often change their location in different versions of the firmware, which causes confusion among users. In this article, we will detail each step that will allow you to forget about the problems with connecting wearable devices.
The right energy-saving configuration is key to a stable operation of the entire smart home ecosystem. If you want real-time notifications and accurate activity statistics, you can't ignore these settings. Standard out-of-the-box settings are usually not enough to properly operate the tracker's background services. Let's get to the practical side and set up your smartphone correctly.
Preparation for configuration and version verification
Before you change system settings, you need to make sure that the device has an up-to-date version of the software installed. Older versions of the Mi Fit application may not display correctly in the Task Manager or have vulnerabilities that prevent stable operation.
It’s also important to understand that Xiaomi has been pushing a new Xiaomi Wear (or Mi Fitness) app since recently, which is gradually replacing the classic Mi Fit. If you’re using newer bracelet models, it may already be offering you migration.
- 📱 Make sure that Bluetooth is on and working correctly.
- 🔄 Check for updates in Google Play or App Store.
- 🔋 Charge your smartphone to at least 20% before setting up.
Special attention should be paid to access rights. When you first run the application asks for a lot of permissions, and if you accidentally denied access to geolocation or background work, the synchronization will be interrupted. It is critical to allow the application to access the location constantly, not only when in use, as this is often required for correct tracking of routes and operation of the Bluetooth scanner.
Auto-start configuration in the MIUI system
The first and most important step is to activate autostart. In the shell, MIUI is a separate mechanism that controls which apps can be launched immediately after the phone is turned on, and by default, this feature is disabled for most programs for security and resource saving.
To access settings, go to Settings → Apps → Permissions → Autostart. In the list that opens, find Mi Fit and activate the switch opposite it. If you can’t find this item through the general settings, use the built-in Security app (green zipper icon) that is preinstalled on all Xiaomi smartphones.
☑️ Auto-start setup
Once the autorun is enabled, the system may issue a warning that this action may increase battery consumption. This is a standard message that can be ignored, since the tracker's background operation consumes minimal energy compared to the benefits of stable synchronization. Without this step, the operating system will block the application from trying to connect to the wristband after the device has restarted.
⚠️ Attention: Some global firmware versions may have different paths to autorun. If the standard path doesn't work, search for settings by entering the word "autorun».
Disabling battery saving for the application
The next critical step is to set up a power saving strategy specifically for Mi Fit. The default system puts all applications in "Energy Saving" mode, which limits their background activity, and we need to put the application in "No Limits" mode.
Go to Settings → Applications → All apps, find in the Mi Fit list and click on Activity Control (or “Saving Charge”). In the menu that opens, select the No Limits option. This action will tell the system not to “sleep” the application process, even if the phone screen is turned off.
| Mode of work | Impact on Mi Fit | Recommendation |
|---|---|---|
| Saving energy | The app closes in 10 minutes | Not suitable. |
| Smart mode. | The system decides when to close. | Unstable. |
| No restrictions. | The app is constantly working. | Recommended |
After the change of mode, the system can warn you several times about the possible increase in charge consumption. Confirm your actions. This change is key for the operation of any wearable devices, as they require constant maintenance of Bluetooth connection and periodic background synchronization of data.
💡
If after restarting the phone settings are reset, check whether you have activated the mode "Ultra-savings", which forcibly closes all background processes.
Fixing the application in memory
Even after the permissions are set, the smartphone’s RAM can become overcrowded, and the system will start unloading long-running applications, so to prevent this, you need to pin Mi Fit on the list of running tasks, which will create an anchor that will tell the task manager that this application can not be touched.
Open the menu of running apps (swipe from the bottom up with a hold or menu button). Find the Mi Fit window, pinch it with your finger, and in the context menu that appears, select the Lock icon. Now the lock symbol will appear next to the app icon, which means it is protected from forced cleansing by the Close All button.
- 🔒 Open the Manager of running tasks.
- 📲 Find the Mi Fit application card.
- 🔐 Click on the lock to lock the application.
It’s worth noting that on smartphones with a small amount of RAM (3-4 GB), this method works most effectively. On flagship devices with a large amount of memory, the system less often resorts to aggressive cleaning, but fixing will still be unnecessary.
What to do if the lock is not on the menu?
Additional permissions and notifications
To work properly, the tracker requires not only the rights to launch, but also access to certain functions of the phone. Often users do not attach importance to the request for access to contacts or call log, but this is what allows you to display the name of the caller on the screen of the bracelet.
In the app permissions section (Settings → Applications → Mi Fit → Permissions), make sure that the following items are activated: Contacts, Call Log, Notifications and Physical Activity. Without the right to “Physical Activity”, the pedometer may not work when the phone is locked.
⚠️ Note: Android 12 and above requires geolocation enabled to operate the Bluetooth scanner. If the bracelet does not find the devices when pairing, check if access to the location is allowed.
Also, look at the notification settings themselves. Inside the Mi Fit app, in Profile → Settings → Application notifications, activate the services you want to see on your wrist. If you don't select anything here, the bracelet will remain silent even if all system settings are correct.
Solving Bluetooth and Reconnection Problems
Sometimes the software settings are correct, but the connection still breaks, in which case the problem may lie in the Bluetooth cache or conflict of protocol versions. First of all, try rebooting the Bluetooth module: turn it off in the notification curtain and turn it on again in 10 seconds.
If that doesn’t work, reset your Bluetooth settings. Go to Settings → Connected Devices → Connection settings → Bluetooth and click Reset Bluetooth settings (the path may vary depending on the Android version).
adb shell pm clear com.xiaomi.hm.healthThe above command for ADB (Android Debug Bridge) allows you to completely clear the application data if a standard reset through the menu does not help. Use this method only as a last resort, since it will delete all local settings of the application. Once you execute the command, the application will start as new and you will need to re-authorize.
💡
If nothing helps, try uninstalling the app, restarting the phone, and installing Mi Fit again, setting all permissions right away when you first start.
