Apple Pencil Gen 2 battery stuck at 100% even after 30 minutes of use

Hello, I have a problem with my Apple Pencil gen 2. The issue lies with the battery indicator or information in the widget; the Apple Pencil battery stuck at 100% even after 30 minutes of use (the Apple Pencil still functions normally). I've already tried restarting and rebooting, but the problem persists a few hours later. Is this a software or hardware issue?
