Several Chromebook users have complained of poorer performance after Chrome OS update. It concerns version 91.0.4472.147, the most recent stable version of the operating system.
The bug was initially reported on Reddit . Since then, the issue has also appeared in the Chromium Bug Tracker . Users report there that the CPU usage of their Chromebooks after the update is unusually high, even if no applications are open. Sometimes the CPU usage would be fixed at 99 percent.
As a result, several Chromebook users report significant performance drops in the Chrome browser and other parts of the operating system. One Reddit user states that typing in the terminal is also slow on his device. A few report that the problem persists after a factory reset and disabling all Chrome extensions.
It’s not clear how many Chromebooks are experiencing performance issues after the recent Chrome OS update. Android Police writes that the problem is mainly reported by Chromebook users with the board name ‘grunt’ or ‘hatch’. At the same time, not everyone affected has shared enough details about their device. So it’s not clear whether the problem only occurs on such Chromebooks.
In any case, it is recommended to wait a few days before updating to this version of Chrome OS. For example, users can prevent the update by not shutting down their laptop, Android Police also writes. Regular Chromebook users have no option to turn off automatic updates.
