So something bigger going on than specific cars... I've got a portable wireless charger, a Tzumi model 5751 wireless 'fast' charger on my desk, and used for a couple years with airpods pro. Tested just now, and begins to charge right away. Charger's fine.
My iPhone 15 Pro when I got it in September would charge on it, though with a bit of wrangling of the position to align the coils (It doesn't have any magnetic alignment, and the camera bump I'm thinking at some angles causes the phone to rise a bit, and not have a good solid connection). As I've gone through 17.1, 17.2 betas, the connectivity chances have been less and less. None of the 17.2 betas have once got my phone charging wirelessly.
