The phone doesnt warm up at all when I try to charge it and I’ve tested multiple charging cables of apple to make sure they arent bad. I just replaced the lightning port hoping that was the culprit. Battery doesnt look bad but is there a way to test it? Or what could you recommend I try now. Thank you.

Even if there’s no battery it should to something so don’t worry about the battery. Have you tried plugging it into a computer and seeing if the computer recognises it?
