Mobile Light-Problem

Hi there,
today I tried some stuff for mobile and one thing I noticed was the poor quality of the light rendering on mobile.

I’m pretty sure that this is something I need to setup in the editor before launch on mobile, but I cannot figure out what it is.

Maybe someone of you can help me?

I just created a new Third-Person-Project with Mobile/High Quality as Target and add some PointLights, then launched it on my iPhone.

Have a look at the screenshots. One is on my computer in the editor and one from my iPhone.

BTW: That are static lights, if I turn them movable, all looks pretty.
