My history: * 5 nights ago (Monday night in US), went to sleep w/ 84%, woke up w/ watch dead (off and won't start). * 4 nights ago (Tuesday night in US), fully charged before bed, went from 100% to 17% overnight. * Live Chat w/ Customer Service; they had me do reset. * 3 nights ago (Wednesday night in US), battery drained overnight. * 2 nights ago, put it on the charger before bed and forgot to wear it bed. On the charger in the morning it was at 100%. * Yesterday: AN UPDATE WAS PUSHED TO MY SAMSUNG GALAXY PHONE, AND I INSTALLED IT. * Last night, I fully charged watch before bed, put it on, and this morning it is at 94%. So, I conclude that either: (a) the bug doesn't work on Friday nights; or, (b) the update to my phone altered the universe.
