This process (mdnsd) drained my battery for a few weeks. I have not been able to find a solution after a lot of research.
I have no drone application, Facebook or Firefox, although the problem has more or less started when I installed the Firefox application. But I uninstalled it, restarted my phone and the problem is still there, which makes me think that Firefox may have nothing to do with it.
Ideas? I have a LG G2, Android 4.4.2
