I've used this dock for a couple years now: http://www.amazon.com/iMagnet-Cradle-less-Universal-Windshield-Dashboard/dp/B008IOQ3K6

I'm currently using the Spigen Neo Hybrid case: http://www.spigen.com/collections/galaxy-note-5/products/galaxy-note-5-case-neo-hybrid-carbon?variant=4092381569

And this small metal plate: http://www.amazon.com/iMagnet-Round-Metal-Non-Adhesive-Mount/dp/B00BSA6MOY/ref=pd_sim_107_3?ie=UTF8&dpID=31OQvtjSaEL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0214A09S6JYRAP94B0E4

I have the round plate taped to the inside of my case, just below the middle of phone.

NFC works normally and wireless charging also works normally.

I imagine if you use one of the larger metal plates you'll have issues with wireless charging and NFC. Stick with this method above and you'll be just fine.
