Are there any devices that allow a replaceable battery and wireless charging? I know battery swapping can become common, but I also do not want to lose a feature that I currently enjoy.
Yes, we had this ability all the way back in 2012 on the Galaxy S3, which had NFC and Wireless Charging built in to a user replaceable battery pack. It was available on many phones in that era and could easily be brought back if we gave up some "thinness" that we have now.
I can't think of any reason a battery being removable would impact its ability to wirelessly charge (though it would still need to be in the device to do so).
you could easily add a charging coil in the back of the phone and just have some contacts
my fairphone 4 already has a pair of contacts on its back, with accompanying pogo pins in the body, although i think that's just for an nfc antenna. still, the same system would totally work
