Is this even normal?

I'm trying to figure out why my redmi note 12 pro 5g charges so slowly at any battery level, I've tried with any type of charger and cable and it never goes over the 8w threshold. I started noticing a performance degradation after switching to HyperOs. More than 3 hours from 20% to 100% is atrocious, should I throw away my phone or is there something I can do?

I would be so pissed off to have a fairly recent phone that works fine
