title: Safe value of energy impact in iOS
body: <p>I have created an iOS app and it's first phase is almost complete. Basic flow of app is that a user can add his offer. Other users can avail this offer by booking it. The number of offers keeps on increasing/updating therefore all the data in app is loaded from server. 
  Now in the debug navigator, all values are more or less within safe area (green area) as shown: </p>

  <p>But the energy impact is: </p>
  
  <p><a href="https://i.stack.imgur.com/u6CFG.png" rel="noreferrer"><img src="https://i.stack.imgur.com/u6CFG.png" alt="enter image description here"></a>
  This is the at the time when app is requesting server to load items in list. Now my questions are:</p>
  
  <ol>
  <li>What energy impact exactly is? (searched but couldn't find anything to have proper understanding)</li>
  <li>What are possible reasons of its high value? </li>
  <li>What is it's safe value? Do I need to try to make it low?</li>
  <li>If yes, then what possible approach I can try to make it low?</li>
  </ol>
  
  <p>Moreover, even if the user is not interacting with the app the energy impact is (not exactly zero): </p>

  <p>Whereas according to apple docs:</p>
  
  <blockquote>
    <p>When the user isn’t interacting with your app, there should be no
    energy impact.</p>
  </blockquote>
  
  <p>Any help would be appreciated, as I am a newbie to iOS. </p>
