6:30am to 10:30pm for me today, and I'm at 11%. That's 16 hours, and I played with Facer a lot today, and had a crap load of notifications as well. I did have a hell of a time getting Facer and the new Android Wear playing nicely with the Moto 360 after the update, and ended up doing a complete removal and reinstall of Facer and a reset of the watch. I definitely cleared the cache on Android Wear, and may have even performed a reinstall of it, but I wouldn't swear to that last one. In any case, a reset may of your watch and clearing your Android Wear cache can't hurt. I removed Facer because it showing up twice in my watch.
