Does enabling Wi-Fi drain more or less battery when tracking location?
<p>I have a mobile app (iOS and Android) that pings the location ~ every 15 seconds and is used in urban areas.</p>

<p>From my understanding</p>

<ul>
<li>If Wi-Fi is disabled the app will use just GPS for location</li>
<li>If Wi-Fi is enabled the app will either use a mixture of Wi-Fi and GPS or just Wi-Fi</li>
</ul>

<p>Generally Wi-Fi on drains more battery however if you are tracking location then it might actually save battery since GPS is more battery intensive than Wi-Fi (I think!)</p>

<p>Does anyone have data if enabling (but not connecting to) Wi-Fi will be better or worse for battery life?</p>
