My iPhone x only turns on when pluged in charger then it flashes logo?

Hii

I have a iphone x and i replaced its screen and battery the other day reason was battery was dieing within 1 hour and i broke my screen by pressing to hard on it so i Decided to replace both and few months everything worked well and few moments i mean 1-10 minutes then my phone just switched off

When i plug my phone into a charger wither wireless or lighting cable it starts flashing apple logo nonstop and when i take the charger out the phone turns off completely and the phone would flash apple logo and then 1 in 100 chances it turns on to home screen then it doesnt charge it says 0% charged and then turns back off in like 1-5 minutes and starts flashing apple logo again and it does it over and over.

I tired force restarting/hard restarting it and i tried factory settings all settings nothing worked i put the old battery back in and even changed chargers still nothing and i pluged sum flex cables out and just left screen and battery in still nothing when i plug it into a desktop or laptop the phone doesnt even come up to the PC at all so i cant use itunes to see whats going on nothing

Please i need help idk whats going on with this phone
