That reminds me, if your Moto 360 ever dies while you're watching a movie, be prepared to hear your phone notifications return. Once your phone disconnects from it, it'll exit silent mode even if you set all volumes to silent manually.
I know this because due to an unfortunate combination of the watch dying while in a theater, Moto X thinking I'm traveling even after sitting still for over an hour, and having Touchless controls read my text messages out loud automatically when I'm driving, everyone in that theater probably heard my phone asking me if I wanted my text message read out loud. On top of that, because I couldn't say anything to cancel out of that mode while trying to desperately pull my phone from out of my backpack to shut it off, it kept requesting "What's that? Couldn't hear you. What's that? Couldn't hear you. Okay, maybe next time."
Thankfully they fixed that battery drain for the 360 but I now have my phone off whenever I'm in a movie. Never had an issue with it just being in silent up until that point.
