Auto reboot mode repeating

A repeating auto-reboot loop on a Redmi 12 can be caused by software corruption, a problematic update, a failing battery, or another hardware issue. I’d first try entering Recovery Mode and clearing the cache if that option is available, then check whether the phone can boot in Safe Mode. If the problem began after an update or app installation, that may help identify the cause. If none of these steps work, backing up data and considering a factory reset or professional diagnosis would be reasonable. TekRevol also emphasizes systematic troubleshooting when evaluating mobile software and device related issues.
