How to see data usage across devices

Hi, @user_a5c802. Thank you for reaching out. I hope you are doing well today. I understand you saw an increase in your data usage, and you want to find what device using the most data. For privacy and security, we don't monitor the data usage by device. You could use the parental controls and Xfinity App to pause devices, so you can narrow things down by process of elimination during the day. I know this will take a bit longer, but we don't have a list that displays usage by device. 

@user_a5c802  I know this is not the answer you were hoping for, but I hope this helps you along the way. Have you had any changes as far as the number of devices you have online, or any new services you've added? As you can read here https://www.xfinity.com/support/articles/xfinity-internet-background-data-usage there are programs and apps that can run in the background adding to overall usage. There you will also find the following:

Programs that Use Data in the Background
A wide range of programs and mobile apps continue to use data even when they are only running in the background. These may include:

• Photo Backup Services such as Google Photos, Amazon Prime Photos and Apple iCloud
• Document and Data Backup Services such as Microsoft OneDrive, Google Drive, Apple iCloud, Dropbox and Box
• Music and Video Streaming Services such as Spotify, Pandora, Amazon Music, Google Play Music, YouTube, Hulu, Vudu, Amazon Movies, Google Play Movies and Xfinity Stream
• Filesharing, P2P and Torrent Programs
• Software Updates for operating systems such as Microsoft Windows or gaming services such as Steam

I also wanted to provide more great links as well like https://www.xfinity.com/support/articles/data-usage-what-counts-towards-my-data-plan that goes over what exactly counts towards your data. This link https://www.xfinity.com/support/articles/data-usage-avoid-overage-charges has great tips and ideas to help conserve data usage. Lastly, we have a great article here https://www.xfinity.com/hub/internet/internet-data-usage which also has great tips on maximizing your data.

Knowing that you cannot see which device is using the most data will definitely send me looking for another provider!  

xfinity, 

I am requesting my per device data usage. My previous xfinity modem allowed for this viewing. I would like a breakdown of the data usage as I would like to double check your usage calculation. Based on the examination of the data usage on my devices I have not come up with the same tally. 

Please stop using that same old tired line "For privacy and security reasons, we don’t have access to find out how much data each device is using." Your equipment logs equipment MAC addresses, that is literally an equipments fingerprint. Your router seems really smart, and I am sure it receives updates, which makes me wonder are your customers paying for updates for your equipment? Is that why you don't show device usage? 

I'm with the other people commenting in here.  My data usage has more than doubled in the first half of this month, yet I have checked computers and phones and usage is low.  The only thing I can't check is two roku streaming devices.  We have cable TV so 95% of our viewing time is on cable, with about 5% streaming.  The Rokus were set to 1080p, now 720.  Streaming has averaged an estimated 7 hours per day total, NOT per TV.  Streaming should be less than late December when I was home and quarantined and streaming a lot.  I have checked devices on my network and everything else I can check.  I can't check data usage for the rokus.  You aren't really protecting our privacy by not providing per device usage, you are preventing us from accessing our own information!  If my data usage has more than doubled, with habits that should be using less data, then clearly there is a problem and you aren't helping me find the source of the problem!  What can I do?  And no, offering me a sales pitch is not a solution to a device bleeding data that needs to be fixed!

I am experiencing a similar issue.  All the sudden in December my data usage doubled from and average around 500 a month to over the 1.2.  I am not doing anything different.  What is consuming all the data?

And please don't tell me to pause devices in an effort to try and find the culprit device.  That is an extraordinarily infeasible solution.  The only way that could even be remotely possible is if you were able to prove daily usage where I could tell in a days time whether pausing a device had any impact.

Same problem here — My usage has been a steady 500-600 gb/month every single month since i started using xfinity almost a year ago, but all of a sudden in December it inexplicably doubled. Absolutely nothing changed or increased with regard to my habits, in fact unlike any other month since I started using xfinity, my house actually sat completely empty for 10 days in December while I was away with family, everything was off & my house was empty/no one using anything for 10 out of the 31 days. Yet my data usage was all of a sudden double the very steady consistent usage amount I’ve had being home daily, month over month for the last 10 months.

And now in January, it’s the 18th & I’ve just received a notification (for the first time ever) that I’ve used 90% of my data for the month. Which is what sparked all this/me even looking INTO my usage to know it doubled what was normal for me in December out of nowhere.  Even with December’s huge spike, I still never got a notification that I’d used 90% of it. And Now just 18 days into January I’ve already surpassed the data usage for the whole cycle of last month. 

First thing I tried to do was look into usage by device, since something is clearly wrong.

Finding out that this is not an option is aggravating enough, but what really twists the knife is the “for privacy & security” reason… The explanation of “this info is not available because we respect your privacy & security, your data usage is personal & private so we don’t do that — Well, the equipment that you pay for does monitor & log this information, and someone in our company does have access to it, but for your privacy the information is not available to you — your data usage by device is private, but not to YOU, it’s private to someone that is NOT you — for your security of course” it’s just a bananas explanation. First of all, treating “the ability to know that my kid’s iPad is sucking more data than my TV” like it’s the watergate tapes is a joke. It’s so transparent, xfinity has no interest in usage transparency + making it easy for consumers to fix data bleeds/easily curtail undesired usage, because why would they. Evidenced by the fact that ever since I got this 90% notification today (while I was at work & house empty/zero data being actively used, btw), I’ve been notified 4 different times that “there are charges for overages, there are charges for overages, hey you’re almost there & there are charges for overages — but hey all the more reason to sign up for unlimited! Do it! Sign up for unlimited! SIGN UP FOR UNLIMITED! Sign up for unlimited.” It’s pretty wild for a service that charges people based on usage to see no issue with providing zero transparency into that usage. Especially when it’s so industry standard by all of your competitors. You guys can say I used whatever you want, and my only recourse is to, idk, call some random 800 # & spend X amount of my life trying to get in touch with this secret society of folks that xfinity has deemed more trustworthy with my uber private in home usage by device info, than literally me. The person that owns the home, owns the devices, pays for the data, and is doing the using. That, after hopping online of course to burn some more data just to figure out that’s my only option in the first place. 

Come up with a better answer, guys. I think I’d rather just have found out the equipment doesn’t monitor it. 

Signed, 

Definitely going over this month just to be able to write you this comment
