Thank you for your bug report, that has been reported upstream on https://gitlab.gnome.org/GNOME/gnome-control-center/issues/305 and you should better comment there about your usecase (having a faulty battery is probably not going to convince them to add values that are not useful to most users though)
Note also that you can change the value to something not in the UI by using gsetting set org.gnome.settings-daemon.plugins.power sleep- inactive-battery-timeout <value in second> ** Bug watch added: gitlab.gnome.org/GNOME/gnome-control-center/issues #305 https://gitlab.gnome.org/GNOME/gnome-control-center/issues/305 ** Changed in: gnome-settings-daemon (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-settings-daemon (Ubuntu) Status: New => Triaged ** Package changed: gnome-settings-daemon (Ubuntu) => gnome-control- center (Ubuntu) ** Changed in: gnome-control-center (Ubuntu) Importance: Low => Wishlist ** Also affects: gnome-control-center via https://gitlab.gnome.org/GNOME/gnome-control-center/issues/305 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1825208 Title: Automatic suspend delay is at least 15 mins To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1825208/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
