How to fix Mi Fit in Xiaomi: a guide to setting up

Owners of smartphones brand often face a paradoxical situation: smart watch or fitness bracelet work perfectly in the first hours after purchase, but after a day stop transmitting data. This is due to aggressive energy saving policy in the shell MIUI or HyperOS. The system forcibly closes the background processes, considering them an extra load on the battery, which leads to a break in the connection with wearable electronics.

To avoid missing statistics and missed notifications, you need to manually configure the Mi Fitness app (formerly known as Mi Fit) to run in the background without restrictions. In this article, we will break down all the stages of configuration, from basic resolutions to hidden engineering menus that guarantee a stable 24/7 connection.

Following this guide will help you forget about constant reconnections, and we will look not only at standard methods, but also at specific settings for different versions of the Android operating system, adapted to the logic of the Snapdragon and MediaTek processors.

Application installation and initial authorization

The first step is to install the software correctly, and many users download modified versions from third-party sources, which can lead to instability. Use the official Google Play store or AppGallery to download the current version of Mi Fitness.

Once installed, launch the app and log into your Xiaomi Account, and it's the cloud service that allows you to sync data between devices, and if you don't have an account, the sign-up process takes no more than two minutes.

⚠️ Note: When logging into an account on a new device, the system may request a confirmation code by SMS Or through a push notification on an old gadget.

In the initial search phase, make sure that Bluetooth is on and visible to everyone. The app will request a number of permissions, including access to geolocation. This is a mandatory requirement of the Bluetooth Low Energy protocol for peripheral scanning, even if you don't need route tracking yet.

💡

When you first connect the bracelet, update its firmware through the app, which often solves 90% of connection breaks in the future.

Set up Android permissions and accesses

Modern versions of Android (10, 11, 12, 13 and 14) have strict privacy rules. To secure Mi Fit in the system, you need to give the application maximum rights. Go to your smartphone settings, find the Applications section and select Mi Fitness.

In the Permissions menu, make sure that the items “Location” (always) and “Bluetooth”, “Notifications” and “Phone” are activated. Lack of access to the phone can block the caller’s name from displaying on the bracelet screen.

• 📍 Geolocation: necessary for work GPS-tracking and scanning BLE-device.
• 📞 Phone: Required to synchronize phone book and call log.
• 📸 Camera: Needed if you plan to use the Remote Shutter feature.
• 📂 Files: allows you to save dials and update tracker software.

Pay special attention to the notification settings. In the permissions menu, look for the Notifications item and turn on the icon on the lock screen and in the curtain. Without this step, you will not see vibrations when messages from instant messengers arrive.

Battery Optimization and Auto Startup in MIUI

This is the most critical stage of the setup process. The MIUI shell is known for aggressive memory cleanup, and if you don't configure this partition, the system will kill the synchronization process immediately after you turn off the smartphone screen.

Go to the battery settings and find the Mi Fitness app, and you need to change your energy saving strategy, and the default mode is "Energy Savings," which limits background activity, and switch it to "No Limits."

Next, you need to activate autostart. Find the autostart option in the settings (often located in the Applications section» -> «Permissions.... turn on the switchboard opposite Mi Fitness. This will allow the app to start immediately after the phone is turned on without waiting for the user to manually start.>

⚠️ Note: On some versions MIUI (Auto-run settings may be hidden in the engineering menu or require additional confirmation through the system application "Security».

It's also recommended that you stick the app to a list of recent tasks, open the menu of running apps, find the Mi Fitness card, press it, or press the lock in the corner to lock it in memory, which is a signal to the system not to unload the application when you clean up RAM.

Advanced Bluetooth Settings and Stability

Sometimes standard measures are not enough and deeper interventions are needed to make the Bluetooth stack work. Newer versions of Android have features that can conflict with the tracker’s permanent connection.

In the Bluetooth settings section, find the Device Search or Visibility option. Make sure the phone doesn't go into stealth mode after a certain time. MAC-address for your bracelet, if such option is available in the advanced settings of a particular device.

If you use third-party launchers or themes, try switching to the standard interface.Some heavy topics may conflict with system notification services, which indirectly affects how Mi Fit works.

For users facing persistent breaks, resetting network settings can help. Go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Remember, this action will remove saved passwords from Wi-Fi networks.

Mi Fit vs. Zepp Life and Mi Fitness

Xiaomi’s ecosystem has seen a migration of services, causing confusion: the old Mi Fit app has been renamed Zepp Life, and for new devices (bracelet 6, 7, 8 and watches) a new Mi Fitness app (formerly Xiaomi Wear) has been created.

Key difference: The Mi Fitness app requires Google Play services and only works on Android 6.0+, while Zepp Life is lighter and compatible with a wide range of older devices.

If you have switched to a new bracelet but have stayed in the old app, the functionality may be cut. Be sure to use the manufacturer's recommended software for your gadget model.

Solving Notifications and Vibration Problems

A common complaint of users is that the bracelet vibrates but the message doesn't come, or vice versa. The problem is managing notifications within the app itself. Go to the device profile in the app and select "Application Management."

You need to manually turn on the switches for all messengers that you want to see on your wrist (Telegram, WhatsApp, Viber). If the application is not in the list, click + and add it from the list.

Also check Do Not Disturb (DND) mode if it is activated on the phone or on the bracelet itself, notifications will not arrive. Make sure that the DND settings on the phone do not block all notifications.

⚠️ Note: On Xiaomi smartphones, notifications from some apps can be blocked by the system Accelerator. Add important messengers to the list of antivirus exceptions.

To properly display the notification text, you need to allow access to the notification history, and when you first start or after you update, the application will request this permission, without it, Mi Fit will not be able to physically read the text of the incoming message.

Additional advice and frequently asked questions

For advanced users who want to get the perfect job, there is a cold start technique: Close the app completely, turn off Bluetooth, restart the phone, turn on Bluetooth and then launch the app, which helps to reset the suspended services.

If nothing helps, try removing the device from your phone's Bluetooth settings (forget the device), but don't remove it from the app. Then re-pair through the Mi Fitness application interface.

💡

The main secret of stability is a combination of three actions: autostart permission, removing battery restrictions and fixing the running application in memory (lock).

Check the app itself regularly in the store. Developers often release patches that fix compatibility bugs with new versions of Android.
