I would expect high CPU in general on your laptop because you are using
3840x2160 and gnome-shell is not yet very efficient.
Please use the above bugs, and/or keep an eye on all the work being done
to improve it:

Title:
Gnome shell and Xorg use at least 10% CPU
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Related to Issue #1773959
On a fresh install of Ubuntu 19.04 on a 2019 Dell XPS 13, I have very high
CPU usage from gnome-shell and Xorg (each one is taking up around 10%) when no
other process is running. This increased greatly to more than 20% for
gnome-shell when I enabled showing seconds in the top bar. After disabling
seconds, I went back to ~10% cpu usage for each of those processes again. I
opened this because most of the other relevant issues are closed, expired, or
marked as invalid.
