Custom shadow mapping for mobile

Unity Engine
1

Hi there, I have a small scene. The details are given below:
Scene type: small with at most 20 static mesh renderers
Rendering path: Forward
Platform: Mobile(android/ios)
Shadow type: crisp hard, no soft shadow

I am concerned what unity shadow might do to the game, performance wise. Should I approach my own shadow mapping?

It depend on the mobile specs really.

lets say samsung galaxy J5 is the lowest config, in which game must run smoothly.

You’ll have to research this and their limit (on top of memory issue):
Chipset Qualcomm MSM8916 Snapdragon 410 (28 nm)
CPU Quad-core 1.2 GHz Cortex-A53
GPU Adreno 306

I’ll look into it later
