This is common pry damage--there is a tiny row of components that are easy to damage when prying the battery on the logic board side (a big no no).

I feel like every post lately is about board damage, and people not being able to find anyone to fix it. Board-level repairs on the iPhone is exactly what I do, so if you're stuck, feel free to contact me.
