My dog was murdered by a 3.5mm audio port and I will not rest until the standard is dead
seems the same to me on Nexus 4, msm_hsic_host is still causing pretty hefty idle drain.
dunno if Nexus 7 has improved yet though.
Works on my N5 and N10. But the original battery drain for me was Location, which, apparently, the Service update fixed.
