@ollehell I only know about Nexus 4, but it is not that buggy. Its similar as Ubuntu Desktop. Actually, it is surprisingly not buggy in my experience, and I use it for a long time I don't remember. Concerning Morph, I only have 1-3 tabs open at the time (similar on the Desktop, so different kind of habits so did not experience slowness or crashes. Concerning battery, I often had problems a year ago (but used external battery often) before replacing phone battery and now battery is good. For you, maybe its Ubuntu+FP2 issue, maybe its anbox issue as others mentioned (which is not officially ready yet) or battery itself.
