iPhone SE random battery percentage
I bought an SE to repair the screen , I have noticed that when I was driving home the percentage dropt from 73 to 30 and then it get stuck for like an half hour even using it , when I changed the screen I noticed when I replugged the battery in the connector that it doesn't click , it feels like it's lose all the time. Is it possible because of a damaged port or battery that it gives bad readings, because I don't see any metal holder that has broken off. I also don't have an extra battery yet to test it.
Also I don't have a multimeter to test
