Try using the button combo to reboot. Hold down power+volume up+volume down and see if it will reboot.

If it fails to boot into the OS I'd try to flash back to the stock firmware using all of the Odin files.

Did the Samfail process in ODIN fail or did the phone fail during boot?

Either way you should be okay. However if you can't get it to flash back to stock you may have bricked it, at least a softbrick.

2 note 8's samFail Fail!!! HELP!!!

I have 2 Note 8's that I have somehow managed to achieve soft bricks on, on the Sprint variant and the other AT&T, I have researched and odin is failing everytime on both of them :( is there anything anyone has figured out? It says "model mismatch fail" when flashing with odin on each phone, on is a pet project the other is a customer's. Any advice would be much appreciated!!

Yes, BlueFox721 has posted the correct method to get out of upload/cp-crash or some other semi-bricked mode.
To recap it, keep holding down Vol Down + Power buttons only, until you see the screen starts rebooting, then release both buttons. Sometimes the reboot may take up to a few minutes, and make sure that the battery is charged at least 50%, otherwise it will fail.
If it keeps booting back into upload/cp-crash or some other weird mode, then hold down the above buttons again, but this time as soon as you see the reboot, do not release them but also quickly hold down the BIXBY button along with first two, which should kick you into download mode (or use a download jig). Then re-flash with full stock firmware using Odin. You may have to try both the normal and patched versions, sometimes it works with the first or the other (when you see a model fail error).

The less than 100% battery charging issue could be caused by several reasons, here they are:
1. The phone was flashed with an eng-boot/kernel which has a charge limitation built in. To fix it, reflash with full stock firmware.
2. The battery may have weakened or about to go bad (check the voltage and capacity with a multi meter first). To fix it, replace the battery.
3. The charging circuit may have gotten damaged from an over-current spike, or the port has been physically damaged either mechanically or by liquid damage.
To fix it, you can try replacing the small circuit board along with the port, or perform the world famous "BillA Bypass" (lol), whereby I physically modify the main circuit board to force charge the battery by bypassing the charging circuit entirely.

Can you at least boot into download mode in order to reflash the files? Can you even get into recovery mode or anything? What happens when you hold the volume down button and the power button until the phone turns off? Try holding the volume down button and the power button and as soon as the phone shuts off let both of those buttons go and then hold only the volume up button and see what happens.

Nope, the only thing that occurs is the screen shuts off then goes back Upload mode: Unknow error. I even tried UBreakFix store and they couldn't fix it either. It won't go to recovery mode or Download mode at all.

If it was mine I would try flashing something while it's in upload mode just to see what would happen.. Other than that, it sounds like the phone's done for. Maybe it's internal memory quit working?

If you get to the upload mode screen, press volume down + power buttons until the upload mode screen shuts down (screen goes black). IMMEDIATELY press volume up + bixby + power buttons and keep pressing until you see recovery screen

Either way you should be okay. However if you can't get it to flash back to stock you may have bricked it, at least a softbrick.
