How to get Mi Fit to work in the background on Xiaomi: the full guide 2026

Why Mi Fit Stops Working in the Background and How to Fix It

Xiaomi’s Mi Fit app is a key tool for Mi Band fitness bracelets, smart scales and another Mi Ecosystem ecosystem, but many Xiaomi, Redmi or POCO smartphone users are facing a problem: the app stops syncing data, disconnects from the bracelet or shuts down completely within minutes of being folded, due to aggressive battery optimization in MIUI firmware and Android restrictions for background processes.

In this article, we’ll look at all the possible causes of Mi Fit’s instability in the background and offer step-by-step solutions, including hidden MIUI settings that the manufacturer doesn’t advertise. It’s important to understand that the problem isn’t always with the app itself — system services like Google Play Services or Miui Battery Saver are often to blame.

Before you start settings, make sure you have the latest Mi Fit (at 2026, 5.6.0 or later). Older versions may conflict with modern MIUI 14/15 firmware. Also check your bracelet compatibility: for example, the Mi Band 7 Pro requires Android 6.0+ and the Mi Band 8 requires Android 8.0+.

1. Basic Mi Fit settings for background work

Start by checking the obvious parameters in the app itself, and users often miss key options that directly affect the stability of the bracelet.

Open Mi Fit, go to Profile → Settings → Notifications and make sure:

• 🔔 Notifications from the application are enabled (allowance to withdraw alerts).
• 📱 Activated option "Show notifications on the lock screen" (important for Android 12)+).

Special attention should be paid to Profile → Mi Band → Connection settings. This should include the "Maintain Connection" option, which force the Bluetooth connection to be active even when the application is folded. If this option is not available, upgrade the Mi Fit to the latest version.

Battery optimization in MIUI: disable restrictions

MIUI firmware is known for aggressively optimizing application background activity, and even if you manually let Mi Fit run in the background, the system can block it after a few hours, and to avoid that, you need to turn off battery optimization for the application.

Do the following:

1. Go to Settings → Applications → Application Management.
2. Find Mi Fit in the list and select it.
3. Tapping on Battery Optimization (or Energy Consumption in newer versions of MIUI)
4. Select “No Limits” (or “Not Optimize”).

For MIUI 14/15, the path may be different: Settings → Battery and Performance → Battery Management → Application Selection. Find Mi Fit here and set it to No Limits mode.

💡

If Mi Fit is not listed in the app list, try to find it by the keyword "Mi" or "Xiaomi." Sometimes the system hides utility applications under different names.

Also check the global optimization settings:

• 🔋 Go to Settings. → Battery and productivity → Battery mode.
• 📉 Select “High Performance” (if available) or turn off “Adaptive Mode".
• ⚡ Enable Startup Optimization for Mi Fit (path: Settings) → Annexes → Auto-start).

3. Android resolutions: without them Mi Fit is useless

Mi Fit requires several critical permissions to stay in the background, without which the app won't be able to connect to the bracelet, sync data, or display notifications.

Pay special attention to work permits in the background. In Android 12+, the path to it can be hidden: go to Settings → Apps → Mi Fit → Additional → Permissions → Working in the background and select “Allow”.

If Mi Fit still shuts down after all permissions have been granted, try resetting the permissions:

1. Go to Settings → Applications → Mi Fit → Storage.
2. Click "Clear Cache" and "Reset Permits".
3. Restart the application and grant permissions again.

💡

Without a work permit in the background, Mi Fit will not be able to sync data for longer than 5-10 minutes after curtailment.

4 Hidden MIUI Settings: What Xiaomi Doesn't Tell You

MIUI firmware contains several hidden features that directly affect the background activity of applications. These settings are not documented, but changing them can radically improve the Mi Fit experience.

The first is to limit the processes in the background, to turn it off.

1. Activate Developer Mode (7 taps according to MIUI version in Settings → About Phone).
2. Go to Settings → Additional → For developers.
3. Find the "process limitation" option and select "Standard Limitation" or "No Limitation".
4. Below, turn off MIUI Optimization (if any).

The second hidden setting is the priority of the process.

• 📱 Install Activity Launcher from Google Play.
• 🔍 Find through it "Settings" MIUI" (or Hidden Settings").
• 🛠️ Go to Process Priority and find Mi Fit.
• ⬆️ Set a "high priority" for him".

The third problem is Miui Battery Saver, which is forced to shut down applications to deactivate them.

adb shell pm disable-user --user 0 com.miui.powerkeeper

This command will disable the system battery optimization app.Warning: this may increase battery consumption, but will greatly improve the stability of the Mi Fit.

💡

If you don’t have access to ADB, try disabling Miui Battery Saver via AppOps (root required). path: Settings → Apps → App management → Three points → Special access → AppOps → com.miui.powerkeeper → Ignore battery optimization.

5. Bluetooth problems: why the connection is broken

Mi Fit's unstable performance in the background is often associated with Bluetooth issues. MIUI firmware can limit the power consumption of the Bluetooth module, which leads to a communication break with the bracelet. Here's how to fix this:

First, check the Bluetooth version on your smartphone:

• 📱 Xiaomi 12/13/14, Redmi K50/K60, POCO F4/F5 — Bluetooth support 5.2/5.3.
• 📱 Redmi Note 10/11, POCO X3/X4 — Bluetooth 5.0/5.1.
• 📱 Outdated models (Redmi) 9, Mi A3) — Bluetooth 4.2, What could be causing problems with the Mi Band? 7/8.

If your smartphone supports Bluetooth 5.0+, but the connection is still broken:

1. Go to Settings → Connections → Bluetooth.
2. Slip on "Additional" (cog in upper right corner).
3. Turn on "Constant Scanning" and "High Audio Quality" (yes, this affects communication stability as well).
4. Turn off Adaptive Bluetooth (if any).

The MIUI 14+ option is also available for Connection Priority:

Settings → Connections → Bluetooth → Settings (cog) → Connection Priority → Select your Mi Band

6. Alternative solutions: if nothing helps

If after all the manipulations, Mi Fit still shuts down in the background, consider alternative approaches. They require more effort, but are guaranteed to solve the problem.

Method 1: Notify for Mi Band (requires root)

Freeyourstream’s Notify for Mi Band app lets you bypass MIUI restrictions and provides stable sync. Install it from Google Play and:

• 🔧 Provide root access (or use it) ADB circumvention).
• 📶 Enable the "Keep Alive" option in the app settings.
• 🔄 Turn off autosynchronization in standard Mi Fit to avoid conflicts.

Method 2: Recoil on the old version of Mi Fit

Sometimes newer versions of Mi Fit contain bugs, especially on custom firmware. Try to roll back to version 4.6.0 (stable for MIUI 12-14):

1. Download APK from APKCombo.
2. Remove the current version of Mi Fit.
3. Install the downloaded APK by disabling the source check in Settings → Security.

Method 3: Reset bracelet settings

If the problem is with only one bracelet, perform a hard reset:

• 🔋 Charge the bracelet to 100%.
• 📱 Untie him in Mi Fit (profile) → Mi Band → Untie the device).
• 🔄 On the bracelet: Settings → Reset → Confirm (for Mi Band) 7/8 hold the button 10 seconds).
• 🔗 Reconnect the bracelet.

💡

If you use custom firmware (like LineageOS or Pixel Experience), the problem may be the lack of Xiaomi services.Install Miui Framework via Magisk for full compatibility.

⚠️ WARNING: When using Notify for Mi Band or rollback on an older version of Mi Fit, you may lose access to some features such as Mi Pay or Xiaomi Cloud.Before experimenting, back up your bracelet data to Profile → Mi Band → Backup.
