I am only using to charge. I like having the dock because the phone is upright, within arms reach, and faces me at my desk.
If you have any suggestions/advice, I would like to know.
Thanks.
There is an inductive charging technology with an international Standard called Qi. You put a metal coil receiver inside the back of the phone and get a Qi charger which has a matching coil in it. When you put the phone on the charger they detect each other's proximity and the phone starts charging through magnetic induction without the need to plug it in. And yes it does work through a case.
With the S5 the only coil you can install and retain the S5's water resistance is a replacement back cover made by Samsung. If you don't care about the water resistance there are a number of aftermarket Qi receivers that you can install between the battery and the back cover you have already. The Samsung Qi cover increases the thickness of the phone a little, just enough to prevent most existing cases to fit, but there are three cases that do fit. My S5 has the Samsung back but my wife's S5 has an aftermarket coil inside her gold AT&T phone. They both work well.
There are two very good tilted chargers available. One is the Tylt-Vu charger on Amazon. The other, less expensive one is sold on eBay - search on "A6 QI Wireless Charger Charging Pad Transmitter For Apple Samsung Google HTC LG" if they don't let me add the URL here

That one is half the price of the Tylt but takes 10 days to get delivered to the US from Hong Kong. My wife and I have five of them between our home and our workplaces so we're obviously happy with them.
The inductive charging is about a third as fast as the Sammy wired charger but you tend not to care about that because you just lay the phone on the charger and pick it up when you need to.
So, that's the story. You buy the Samsung back and get one of the 3 cases made for it, or you add a Qi receiver. And you get a tilted charger. But be careful about the term "tilted charger" - there are cheap ones that are like hockey pucks which do work but they're not tilted very much. A real tilted charger has to have a lip at the bottom to keep your phone from sliding off.
