Android Lightmaps are significantly darker with Mobile/Lightmapped Shader

Unity Engine

I’ve got a problem here regarding the Lightmaps in my scene.

My Mesh is using the Mobile/Unlit (Supports Lightmap) Shader. I’ve been working on the scene for Desktop Plattforms but after I’ve switched to Android all of a sudden the Lightmaps are only being baked at roughly half the intensity. The Lightprobes are still the original intensity. So if I just increase the Light Intensities for my whole scene all the Items lit by Lightprobes suddenly also become twice as bright.
I’m working in Unity 5.3.5f1 and cannot upgrade the project in this pahse any more.

Has anyone else encountered this Problem yet?

(Update) Okay - it’s the shader it seems. The Legacy Diffuse/Lightmap and the Standard shader seem okay. At least at first glance.

How come the mobile deidacted shader has problems on the mobile Plattform?
