It is also possible that the charging port of the mobile phone is loose and cannot be connected with the charging port of the mobile phone, which will also cause it to fail to charge.

Damaged data cable or charging head: Due to damage to the charging head and data cable, the current will not be able to flow through the line or the head, which will also cause the final current to not flow into the mobile phone, and the mobile phone will not be charged.

The failure of the Redmi K30 Pro that cannot be charged may be caused by the cracking of the pins of the secondary motherboard, it is recommended to contact the repair network for repair through Xiaomi customer service.

In fact, the root of the problem is that Xiaomi uses 36W high-power fast charging on K30Pro, and the charging speed and current are indeed a bit large, resulting in the micro power strip pins being overwhelmed and cracked by virtual welding, so they can't be charged.

At first, the fault will only occasionally fail to charge, but the check cable and plug will be fine, and then the failure to charge will become more and more frequent, and finally it will not be able to charge at all.
