Due to the page limit, I now wish to reduce the blank space right after a figure (a TikZ drawing).
I personally find it too big.
Below is my MWE. How may I fix it?
\documentclass[a4paper]{article}
\usepackage{lipsum} % for dummy text only
\usepackage{tikz} % for TikZ drawing
\begin{document}
\lipsum
The system architecture is shown in Figure~\ref{fig:systemarchitecture}.
\begin{figure}
\centering
\begin{tikzpicture}[block/.style={draw, fill=white, rectangle, minimum width=0.95*\columnwidth, anchor=west}, font=\small]
\node[block, minimum width=0.9*\columnwidth, minimum height = 3cm, fill=yellow, opacity=1, text opacity=1](phone) at (0,0){};
\end{tikzpicture}
\caption{System Architecture}
\label{fig:systemarchitecture}
\end{figure}
\end{document}

An quick fix without using package is to add a negative length to
which adjust the vertical space before and after the caption, as shown below.
