It shouldn't take 31 hours to update an iPad to iOS 8.1. I updated my iPad Mini 64 is less than 30 minutes. You can usually reboot your device and allow it to pick up where it left off. Oftentimes, it will update at a faster pace. Are you connected to Wi-Fi? Are you upgrading OTA (over the air) or via iTunes?
