@Flohack I realize this might not be the most useful "successful test" but I left my device plugged in and forgot about it behind a couch, and the uptime is >16 days.
If you'd like me to test anything on a device that's been on that long I'd be happy to give it a shot. One thing worth noting is that whenever I do check it, it seems to be disconnected from WiFi and needs me to re-enter the password
