...I do care about the issue of it precluding most cases though. What that means is that for a convenience that you will use maybe once a day you give up all sorts of choices in how you carry the phone. I hated that issue with my Droid.
There is another downside that you are not mentioning. I never knew why, but when phones are on a Qi pad they have a tendency to turn off an on rather spontaneously (Somebody explained why elsewhere in this forum). So if you have the damn thing next to your bed, all of sudden you have the light from the glorious screen on the S4 blazing in your eyes as you try to sleep...
To me though, the issue of having to give up a case I like is a deal breaker. I'd rather just plug in the phone with the USB cable and get to pick from any case I want.
I use wireless charging on my S4 and I have tried several different receivers, as well as the Samsung wireless charging cover. If you want to use the Samsung cover, there is a case on Amazon called Diztronic that will fit over it. It's a matte black, soft TPU case.
There's also 2 main types of receiver inserts: The white ones are about 1.6mm thick, and you will notice the bulge when installed. There's also a black one that is only 0.6mm thick and makes practically no bulge. You can distinguish it because it has the microprocessor on the tongue in between the connector pins and the main body where the charging coil is at.
To eliminate the annoying turning on and off of the phone screen while it's trickle charging, simply enable the dock clock function on the phone, enable the full screen mode, and it will solve that problem.
To activate the dock clock app:
> go to the apps drawer and tap on the clock icon.
> On the top tabs (where it shows Alarm/World Clock/Stopwatch/Timer), swipe it to your left and it will reveal an additional tab for the Desk Clock.
>Once you tap on it, it will reveal the dock clock.
> Tap on the bottom right on your phone (the menu soft key) and you can go into the app settings where you can show/hide the calendar, weather and dock settings.
> If you tap on the "full screen" icon in the upper right, it will go into the screen saver mode. From there you can go into settings again and configure additional options like hide status bar, wallpaper, weather, etc.
The key is to enable the "screen saver" or full screen mode. Otherwise, if an email, text or other notification comes in, it will turn off the dock clock. What I did, is I made an NFC tag that I stuck on my charging plate is that when I place my phone on it, it activates the dock clock. Then I just tap on the full screen icon and it's set for the night.
If you find that the screen is too bright, there's an app called screen filter that dims the screen to your liking. I am using it simultaneously on my NFC tag.
