iPhone 12 Wired charging Concern

I'm using my phone more than 6 months since last 2 months I'm facing problem with wired charging my phone through lightning cable. The problem is battery percentage wouldn't increase while connected wiredly it's like placing the phone idley connected to charger but when I shake the phone it would start charging. I know no issue with lightning cable wire. I'm using charger from apple it could be the issue with charging port on my iPhone. As of now I'm charging my phone wirelessly but it's slow. I want any possible solutions for that. I'm running latest 16.6 version
