So I noticed my 5x doesn't doze on WiFi at home but does on WiFi at work. My router is several years old and is only G no N or AC. Anyone with older routers also noticing this. I would think that with Marshmallow it should be backwards compatible.
Location services are the same whether I'm at home or work so that shouldn't be a problem. I just don't get the same flat line that I see when doze kicks in. It's a steady decline at home.
