I worry about the receiver being bare like that though. You don't think it will cause any damage due to the heat being directly on the battery/door instead of through the coating originally put on it?
Honestly, yes that is a concern. Mudder manufacturers the Qi receiver with a substantial amount of thermal padding on the coil. The exposed coil, to my surprise, was actually also enveloped inside of a plastic film, as pictured. I have ripped apart other Qi receivers, copper wire receivers, to reduce the bulge through the back cover, leaving them exposed and they also produced a fair amount of heat while charging/immediately after being removed from the charging base.
In this useage, since I made these changes to the Mudder receiver, I can say that this setup doesn't get nearly as warm to the touch after being on my Qi pad overnight while charging as the exposed copper wire receivers I have also made changes to does (which is kind of an obvious statement as exposed copper wire will clearly get hotter than this Murder coil which is enveloped in the plastic film).
Personally, I was comfortable with the amount of heat that my original copper wire qi receiver gave off after I made the changes to it, as it was (believe it or not) not much warmer than the use of the receiver before I modified it. Having experienced that setup, I am definitely more confident in the Mudder receiver being used with these changes I made.
Notably, I was using the exposed copper wire reciever for about a month before I found out about the Mudder version, without any problems, and my current setup really doesn't get any warmer to the touch than using the wall plug.
Of course I am running a risk of having an issue since I have modified these products from their original design and intended use, but I am within my comfort-zone based on my experiences. As long as nothing explodes and burns my house down!
Btw, that coating in the Mudder receiver is easily double the thickness of the of the actual receiver.
