I dropped my FP1 today and the battery went immediately from 51% to 18%. I turned it on and it keeps turning itself off after around 5 minutes on, What can I do? I really need my phone and I want to fix it tonight.

Looking at your story/question you most likely have damaged your battery connector or the battery itself, there’s unfortunately nothing you can do, you’ll have to take it to a repair shop to get it fixed.
