Baking lighting looks awful compared to realtime lighting, why?

Unity Engine
1

So I first made a simple scene without any baking, and it looked like this: Microsoft OneDrive

After I used Baked GI, it looks like this: Microsoft OneDrive

What am I doing wrong?

I need to use baked lighting as with realtime lighting the performance on Android is very, very bad (5FPS).

THANK YOU!

Check the settings on Lighting tab and adjust some lighting intensity should help.
