Is there a way to show time remaining in the battery menu?

This used to be a thing on older versions of macOS, but there was a workaround: if you disabled SIP, and then replaced the "Battery.menu" file at /System/Library/CoreServices/Menu Extras. see https://eshop.macsales.com/blog/411...-a-macbooks-battery-time-remaining-indicator/

Does anyone know if this works on Monterey?

That won't work. You can't replace or modify any files in /System without rendering the machine unbootable.

Is that due to some change in macOS, since we used to be able to do that?

EDIT: Regardless, I looked in that path and there isn't a "Battery.menu" file anyways. So if there's a way to do it, it's not at that path.

Yes. Apple is making macOS more secure. Monterey system files reside on a separate volume than user data and that volume is read-only and sealed with a cryptographic signature. Any modification from what Apple installs renders the machine unbootable.
