How to fix
PhoneExperienceHost.exe high CPU usage
on Windows

Hello. I noticed that the PhoneExperienceHost.exe process in Task Manager is using high amounts of CPU. My computer is getting slow. Is there a way to fix this?

When Windows users utilize the Phone Link app, they may see significant CPU[ref en-1] consumption associated with the PhoneExperienceHost.exe process. This executable file and process are essential parts of the Windows Phone Link application, which is meant to make smooth synchronization between smartphones and PCs possible. Enabling customers to handle conversations via the Your Phone app, access multiple apps, media files, messages, and receive notifications straight on their desktops is the main goal of this synchronization.

The user experience is significantly disrupted when the PhoneExperienceHost.exe process shows increased CPU use. The system may become slower, less responsive, and take longer to complete tasks as a result of the increased resource use. These performance problems might negatively impact the computer's overall effectiveness and functionality, which will irritate users who depend on the Phone Link app to seamlessly integrate their devices.

The Phone Link app's primary features are impacted by this high CPU usage. The Your Phone app may not work as intended, making it difficult for users to access synchronized media files and apps, make and take calls, or get timely notifications.

Resolving the high CPU use of PhoneExperienceHost.exe becomes essential for users who want to get their computers back to normal.
