Lightmaps - performance question

Hey Guys!

Ive got a question wich depends on how to use lightmaps. So ive got a scene and i placed differend point lights into it. I used the lightmap option and baked all lights into my scene - so basically i dont need them to be active. The question is: do i have to deaktivate the point lights in my scene to improve the performance of my game? I want to develop for ios/android devices and iam not sure if i have to prepare all of my scenes (deaktivation pointlights). are lights calculated in the background when iam running the game and using lightmaps at the same time?

thanks for answers!
