I had the same problem with 2x redmi note 3 pro. It was supposed that quick chargers interact with the phones before sending higher than 5V though the usb, but apparently, they dont.
The first time, it burned a fuse that is right before the USB connection of the upper board. I had to remove ti with some pliers. After that the phone worked normally, but the phone was unprotected by not having the fuse.
Now, some months later, the phone refuses to charge with many chargers and/or cables. even on the PC it charges only when it is recognized as a device, which makes me think that is a deeper problem, probably, the chip controlling power or charging are half dead. For this phone according to the schematics, the chips are: PMi8952 (power management) or SMB1351 (charger chip). The fuse that needed removal appears as FV2106 in the schematics and it’s a ESD5661D07-2 if you wanna get it of aliexpress and replace it.
-It’s noteworthy taht the lower charging board also has the same fuse. This fuse is expensive, so ALL the chinese fake lower PCB replacement dont have it, they simply replace it with some resistances. If you comapre both board (original and chinese replacments) they differ heavily both in PCB layout and components.
