I replaced the battery and charging port in my device (iPhone 8 plus)

I have replaced the charging port and the battery in the same repair, and it seems like it refuses to charge on lightning for more than a few minutes, and it has been on wireless charging for a pretty significant amount of time and all it shows me is the battery screen. any advice? were the parts I got(at least one of them) defective?

Something to note:

when plugging into a fast lightning charger my phone will vibrate while charging before stopping and it will not charge anymore.

Any advice would be appreciated, the repair was done correctly to my knowledge and I followed all the steps.
