Agreed, I used the Xabber client on Android for years to keep in touch with our entire remote team (20ish people) using a basically out of the box ejabberd server. Never noticed poor battery life or heavy bandwidth usage and the communication was rock solid. Switching back and forth between desktop clients and mobile worked as expected with no weird surprises. All around a great experience, and this was 2011 ish through 2014.
