Just wanted to throw this out there. I have an S7 and have been on chat with Verizon support for the last hour and a half. My started draining faster than it would charge this morning...exactly like what happened with the Oculus update back in September. This time it appears that Facebook and it's related apps might be the culprit. My wife called and told me her and a coworker are experiencing the same issue. Since uninstalling Facebook, Messenger, and Pages Manager, my phone started charging again. Hope this helps someone else who might be frustrated and looking for the source of the same issue.
