What is wrong with the FPS of My Packaged Android Game?

So I’ve been trying to make a game. Now while previewing it into Android ES2 Editor, I’m getting more than 1000+FPS. (Used the Blueprint to set frame limit as 0, hence unlimited FPS) ,but after packaging and running it on Android, i can barely get 30 fps. Now, i have no meshes in my game (for right now), static lights, no shadows, no reflections, HDR disabled in Project settings, nothing that compromise the performance, still not exceeding more than 30FPS on My Moto E4 PLus.
I’ve read almost every thread on Answerhub, reddit, tried every solution, still no changes in performance on Android.

I don’t know how the same image have been uploaded twice. Here is the screenshot of the FPS I’m getting on my cell.
