Windows 11 Phone Link App Causing Severe Memory Issues
The Windows 11 Phone Link application is reportedly causing significant memory consumption and network speed degradation. Users report memory leaks up to 30GB and an 83.33% drop in internet speeds.

Users of the Windows 11 Phone Link application are reporting severe performance issues, primarily related to excessive memory usage. Reports indicate that the app suffers from memory leaks, with some users observing consumption reaching as high as 15 to 30 gigabytes of RAM. This substantial drain on system resources reportedly leads to significant slowdowns, making even basic tasks like opening Task Manager take several minutes.
The issue appears to have been present since at least 2023 and has become a recurring problem for many. Users have resorted to manually terminating the Phone Link process to restore their systems' responsiveness. Beyond memory issues, users are also experiencing dramatic drops in network speeds. One user documented their internet speed falling from 900 Mbps to 150 Mbps, an 83.33% reduction.
Discussions on platforms like Reddit reveal a widespread pattern of complaints. Multiple users have stated that the Phone Link app consumes over 90% of their system's memory, describing the problem as having evolved from occasional glitches to a persistent daily issue for them.
These performance problems with the Phone Link app could negatively impact the overall user experience of Windows 11. While designed for seamless integration between mobile devices and PCs, the application's current resource demands may undermine its utility and degrade the general performance of affected computers.
