Xbox one cache will not clear

My xbox one power cord does not have a power brick. And yes, i get a notification that my xbox one cache is full

You are doing all the right things are you getting a message regarding cache or something leading you to think it is full? You may want to try to full power down and unplug for several minutes for the power brick to fully drain, even if you unplug it
from the back of the console.

Hey
cccrash3r ,

Thank you for reaching out to Xbox forums support.

I'm sorry to hear about your issue trying to clear the cache on your Xbox One console.

If you haven't already done so, go ahead and try performing a Soft console Factory
reset on your console by doing the following:

1. Press the Xbox button to open the guide.
2. Select Settings.
3. Select All Settings.
4. Select System.
5. Select Console info & updates.
6. Select Reset console. [Keep my Games and Apps]

Make sure you have both your email and password on hand as you will be asked to sign back in. There is an option to delete everything and to save your games and apps; choose the latter.

Hope this helps! Let us know!

I was able to make things work with a console reset. Make sure that if you do reset the conles from the settings that you choose the "Reset, but keep my games" option. It will be a bit more work, but should keep you going smoothly for the next four or
so years.

That is how you clear the cache, but there is a separate cache if you watch DVD/BluRays. Go to Settings > Disc & Blu Ray, after that select “persistent storage” then “Clear persistent storage”.

Hope this helps!!
