Android Best performance

Hey guys i got a question

i got a game 1

id like to know which is the best option to performance

Rendering Path :
vertex Lit or forward rendering, both with a directional light no shadows

Light mapping :
At the moment i’m baking a directional light with soft shadows on my scene, does it make a difference if i either have forward rendering or vertex lit selected?
after light mapping i take all lights off

Project Quality
In Edit-Project Setting-Quality when i build my apk to the target platform, does it build it on the setting that is set by default( as green checkmark) or does it build the one currently selected ( i can view thedifferent qualitys in the play/editmodeif i just click on the setting:

Rendering Path:

Since Vertex Lit is the cheapest it is best for performance on low end devices but it does not produce high quality with respect to reality based lighting effect as compared for forward rendering. But the exact answer depends on the devices you are targeting, their performance capability and also the quality of light effects needed.

Light mapping:

If you provide forward rendering then you will have difference in the quality of lightning effect in the lightmap that is baked. Since you are baking lightmaps which are always just static textures and do not need to calculate lighting in each frame being rendered having best quality settings and options selected during lightmaping is what you should do. Since the basic purpose of lightmaps is that you do not require to calculate lights in real time and hence you don’t get performance hit due to number and type of lights used in the scene during lightmapping.

Project Quality In Edit-Project Setting:

Unity uses the current quality settings that are highlighted by you (‘Simple’ is highlighted in image below). If none are highlighted i.e. selected by you then it will use the default setting (green checkmark).
