BMWs wireless chargers are terrible. I had one in my previous one and all it did was make my iPhone hot. I didn’t order it in my current BMW. That’s pretty much the consensus on the BMW forums too.
Edit: I’m wondering if it’s the heat these things produce while charging. They’re supposedly a software fix coming, but mine gets pretty hot sometimes while I’m using it and charging at the same time .
I’ve had 10 BMWs in the last 20 years and I’ve never had any issues, and I have a great service advisor.
