iPhone 6s won’t charge, turn on, or force reset

Basically, a few days ago my phone was charging fine. (I’m using my old phone to post this so as of now it’s just an incovenics) now, it doesn’t say that it’s dead but when I try to force reset it doesn’t work, the screen is just black. It doesn’t show the battery, just black. And I’ve had it on the charger for several hours today.

If it helps, I also dropped my phone a few days ago. Nothing major, but I’m wondering if the battery is dead (it was my mom’s old phone so she gave it to me after she got an 8) or the drop did something to the phone. It was just a little crack on the screen protector but the drop could’ve affected the inside or something.
