Iphone 15 Pro not compatible with some wireless charging devices

The wireless charger I've been using with my iphone 12 pro since it came out does not work with my iphone 15 pro. I put the phone to charge overnight and the battery percentage went down even though it says it was "charging" when I put it to charge.

I saw an article online that this is an issue with some users, and I went to the store to see if I could get a new wireless charger that would work. I tried a few and some of them, including a speaker that had a charger built in, and a 3-in-one charger stand. They did charge my old iphone 12 pro and other people's older model phones but did NOT charge the iphone 15 pro at all despite it saying 'charging'.

Safest bet is to have a charger that has magsafe built in it seems.

Anyone else having these problems?
