This happened to me recently. Factory reset did not resolve the issue. 5 minutes in and it will initialize the VR again. Had to get a replacement phone.

In my case, wifi is also the culprit. Been having cell standby issue the past couple of days. Last night, turned off wifi before I slept. When I woke up, I only lost 2% and no cell standby drain issue.
