Performance issues after building APK for Meta Quest 3

Hi everyone. I'm new to VR development and just created my first VR project in Unity for Meta Quest 3. When I run the game through Unity Link (Oculus Link) from my PC, it works smoothly with good graphics and no lag. My PC has 32 GB RAM and the game uses around 9 GB while running. But when I build it as an APK and run it directly on the Quest 3, I get problems like lagging, lower graphic quality, flickering, and sometimes low memory warnings. I know Quest 3 has only 8 GB RAM, so that might be part of it. But I would really appreciate help on how to optimize the game for Quest 3, what settings or methods I should use to reduce lag and improve quality, and whether there are tools to check what is using up memory on the Quest. Thanks a lot. I'm learning and want to get better at building for VR.

I very recently found "Meta Quest Runtime Optimizer" On the Unity Asset store. 

And Unity's "Project Auditor"  

I have found the "Project Auditor" easier to learn. It did find a lot of small issues and a few  big ones. And almost all of them taught me optimization issues I never thought of.

The Meta one is more difficult to learn and I still am not sure I have it working.

I understand that you're having issues with lag on your quest while building. As RiverExplorer mentioned, the Meta Quest Runtime Optimizer could show you solutions to your lag. https://developers.meta.com/horizon/documentation/unity/unity-quest-runtime-optimizer/.
