Battery percentage should not have a space
Reporting for gnome-control-center 1:41.4-1ubuntu12pop1168295829522.04~2c30e97 The amount of battery left and the percentage symbol should not have a space in between, see also https://en.wikipedia.org/wiki/Percentage for proper usage of percentage symbol.
Advantage is that this provides a little more space for other icons to be shown in the top left corner.
In this screenshot the space should be removed between the 5
and the %

On Android devices and in other software, no space is shown either.
