When Link to Windows stops working on your Xiaomi 15 Ultra, syncing notifications, messages, or photos with your PC suddenly becomes impossible. This can feel frustrating, especially if the feature worked fine before and then failed without warning. Most of the time, the issue is caused by connection settings, app permissions, or a temporary sync problem between your phone and Windows.
Why Link to Windows Is Not Working on Your Xiaomi 15 Ultra
- The Link to Windows app is not properly signed in or synced.
- Bluetooth or Wi Fi is turned off on either device.
- Battery optimization is restricting background activity.
- Required permissions are disabled for the app.
- The Windows PC is no longer paired correctly with your phone.
Make Sure Link to Windows Is Enabled
Link to Windows must be active on your phone before it can communicate with your PC. If the feature is turned off, syncing will fail no matter what you do on Windows.
Open Settings, and then tap Connected devices.
Tap Link to Windows, and then toggle the switch to turn it on.
Check Your Internet and Bluetooth Connection
Link to Windows relies on a stable internet connection and Bluetooth for certain features. If either one is unstable, the connection can break or fail to start.
Open Settings, and then tap Wi Fi.
Make sure Wi Fi is connected, and then check that Bluetooth is turned on.
Sign In to the Same Microsoft Account
Your phone and PC must use the same Microsoft account to sync properly. If the accounts do not match, Link to Windows will not work at all.
Open Link to Windows, and then tap Account.
Sign in with the same Microsoft account used on your Windows PC.
Disable Battery Restrictions for Link to Windows
Battery optimization can stop Link to Windows from running in the background. When this happens, syncing may pause or disconnect repeatedly.
Open Settings, and then tap Apps.
Find Link to Windows, and then set Battery saver to No restrictions.
Reconnect Your Phone to Windows
Sometimes the connection profile becomes corrupted. Reconnecting your devices creates a fresh link and often fixes persistent issues.
Open Link to Windows, and then tap Settings.
Tap Remove device, and then pair your Xiaomi 15 Ultra again from your PC.
Update Link to Windows and System Software
Outdated apps or system software can cause compatibility problems. Keeping everything updated ensures stable performance.
Open Google Play Store, and then search for Link to Windows.
Update the app, and then install any available system updates from Settings.
Once Link to Windows is properly configured, your Xiaomi 15 Ultra should sync smoothly with your PC again. Most issues come down to permissions, battery limits, or account mismatches, and fixing those usually restores the connection immediately.
