The state of mobile XMPP in 2016
https://gultsch.de/xmpp_2016.html

XMPP is a federated chat protocol which has been around for a long time and has a reputation of being bad on mobile devices, e.g. due to unstable connections. Apparently it has come a long way though.

But honestly, the handling of multiple devices when I also want end-to-end encryption is what made me use it less and less. :(
