Hello k.a.christensen, Thanks for running the test. Since there was no usage it seems their was definitely an event within your network that spiked your usage. I did a bit of searching and found a Reddit post that you may find useful for your Xbox One. https://www.reddit.com/r/xboxone/comments/2midcy/whyhow_does_xbox_one_use_so_much_bandwidth/ This person also noticed how much data their Xbox was using without their knowledge. There are some good suggestions to sift through. Hope that helps. As for your Apple device. You can typically see what apps have used the most data etc. I would bet it is the Xbox though. Hope this helps. Thank you, Chris
