And now for zsh, the shell of the gods.  This is just one of the
hojillion ways you can mess with your prompt with zsh.  Just search for
zshrc, zsh, prompt, etc., and you can find examples that have left- and
right-side prompts containing battery info for a laptop:

BTW, the characters shown as "^[" and "^G" are actual control characters
not those ASCII values.  Oh, and there is some cruft from when I had
more complex prompts and terminals that screen didn't alter the titlebar
with.

# Decide if we need to set titlebar text.
local TITLEBAR='%{^[]0;%m:%~ -- zsh^G%}'
local SCREENBAR='%{^[]0;%m:%~ -- zsh^G%}'
local BEGINNING_OF_LINE="%{^[[80D%}"


###
# Finally, the prompt.
case $TERM in
   xterm*|gnome*)
   export PS1="$TITLEBAR\
-- %m:%~ --\

   export PS1="$SCREENBAR\

      export PS1="-- %m:%~ --\

   ;;
esac
