Phone reboots every 3 minutes, reads 0% battery

My iPhone 12 mini reboots every 3 minutes, reads 0% battery when booting back up, and gives me an "important battery message" saying it does not recognize the battery (even though it is the original battery). This began about a week ago and it was manageable because it would only do the reboot cycling for about an hour each day, and then otherwise would work perfectly fine. Now it has been rebooting for 24 hours straight, I took it to Best Buy but they said since there is likely an electronic issue (as opposed to just a battery issue or a cracked screen) that I would need to pay the full $400 for a replacement as Apple would not repair it. Is there any way I can repair this on my own? Panic log is here: https://pastebin.com/tYQ9HqM0

The beginning of the panic log reads:
