Xbox One X shuts off

The Xbox One X will shut off should there be overheating, yes.

That is a known issue under beta preview ring, you are insider preview system?

Hiya Humane,

Thank you for contacting Forum support!

From my experience that's how it is, cause my console acts the same way.

so I usually turn off the control first, then power off the console through the power button.

If you do it the way you're doing it, basically it cuts off the "bind/synced" from the controller and the console.

(This will cause the controller to no longer be "synced" (Temporarily until you resync it by turning on the console and re-binding the control) and will keep it blinking, so you have to remove the batteries.)

Hope this helps

That's the solution I was leaning towards, I'm getting no warnings of possible overheating. I even factory reset my Xbox and the issue is happening more quickly now, I turned the Xbox on and it instantly shut back down. At this point I'm pretty sure it's
a hardware issue as you said.

The best solution will be to take it to your warranty to have it checked, some issues are simply hardware related.
