title: Fragment vs Activity Battery Drain
body: <p>I have been developing each of my "page" in my app using <code>Activity</code>.</p>
  
  <p>I am wondering <em>if this will consume more memory</em> or will this affect <em>performance badly compared to <code>Fragments</code></em>?</p>
  
  <p>Can anyone provide an explanation please?</p>
