Pixel 3 Dropped, no longer holds charge.

I dropped my Pixel 3. No screen damage nor back glass damage however when it came to charging it. It wouldn't hold a charge, after a while it hit 0%. Whenever I plug it in it shows that it's charging however as soon as I unplug it, it shuts down immediately.

It heats up whenever I turn it on while it "charges", around the area behind the camera and fingerprint sensor.

The battery was fine beforehand.

What could be the possible issue(s)?

Are there any tests I can do?
