The phone is not charging or turning on.

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

Troubleshoot your cable, charger, outlet & case

Check that your charger and cable work. Try them with another device. Check that the cable is securely connected to the charger and to your phone. Check that there's nothing in the port of your phone, like dust or lint.

Regards,

Will

Did you try to use electrical tape over the ribbon connectors? Use three small pieces on both the main board connector and the battery connector.

Google translate:

هل حاولت استخدام الشريط الكهربائي فوق موصلات الشريط؟ استخدم قطعتين أو ثلاث قطع صغيرة على كل من موصل اللوحة الرئيسية وموصل البطارية.
