Another lithium battery issue, this time with a mobile phone battery.

A Germania Flug Airbus A321-200, registration HB-JOI performing flight GM-3225 from Pristina (Kosovo) to Zurich (Switzerland), was climbing through FL110 out of Pristina when the crew declared emergency and stopped the climb reporting a phone battery was emitting smoke.
