I mainly have the app installed so I can use the &quot;Nearby Friends&quot; feature as I enjoy spying on my wife and random friends.<p>I think the video calling is pretty good too on the app. Of course the last time I video called someone was in the early 2000&#x27;s using 320x240 webcams so I might be a little biased quality wise.<p>I haven&#x27;t really noticed battery drain but since I normally work at home, I keep my phone on &quot;Airplane&quot; mode so I don&#x27;t waste battery maintaining a cell connection (the phone has wifi calling which can receive calls and sms).<p>This is a samsung galaxy core prime. If I don&#x27;t use it and let it sit there at idle, after 2 days it will have only used 20-30% battery.
