Can this smarphone works without a (possible) protection diode?

While I was replacing the battery, I detached a component with my fingernail. Which component is it?
Someone said this is a protection diode.

Device name: Xiaomi Redmi5 plus
You can see the missing component in the small orange circle.

Yes, it just looks like a regular diode.

If find something in the same package that can handle (say) 1A.

Fortunately the image of the intact board is good enough to see the markings which indicate the cathode.
