I've been playing with it some more.
When it runs out of battery, it just falls to the ground. Since it's so light there's been no damage when it hits grass. But good luck on a hard surface.
It might last 10 minutes on a charge, but that depends on motor speed, camera use, and fighting any wind.
I'm going to tape an Airtag to it in case it drops while over the woods. Otherwise it's impossible to find with its black color.
Regardless, this is a fun little drone for the money!
I've tried difference drones before, and they've ended up frustrating me. I decided to try again, this time with the Holy Stone HS110D FPV RC Drone. It's $30 on Amazon at the moment. You'll need 4 AA batteries for the controller otherwise it has everything else.
What I like about this drone is the display that shows you all of its current settings. The control has trim buttons so when you take off and it drifts you can adjust it to stay in one place.
I also like that it has a "headless" mode. In "normal" mode pressing the stick to go, for example, forward makes it go only in the direction its front camera is facing. But in headless mode pressing forward makes it go away from you no matter which direction the camera faces. This is very helpful for a beginner like me!
