Seemed to be taking and holding a charge until last night. Woke up to a dead phone. Any ideas?

My poco f2 pro had a similar problem. Stopped charging. Seemed to be the usb-c port, but in fact it was the ribbon cable to the USB board (from the battery) that had a bad connection. Opened the ribbon protection plate, cut three-four strips of electrical tape over and tighten the protection plate to give a nice press on the tape/ribbon cable

Apparently it was a little problem for me but to be honest it happened to me after unlocking the bootloader and wanting to install a custom rom. I could not install any return to the normal version of xiomi and everything is normal until one day I restart it, I felt it very slow and it did not turn on like 20 min and one day I turned it off and it did not turn on what I did was remove the battery for 20 min and download the same OTA THAT I HAD FLSHED WITH THE XIAOMI TOOL AND THE PROBLEM WAS SOLVED YOU SHUULD TRY

Not charging and not on
