All I know is that all this fast and wireless charging has made my iPhone 15 Pro's battery health drop quite fast. 10% between launch day and today.
With my Apple Watch Series 10, I went back to the old charging cables with USB-A and I only keep fast charging for when I really need it, and this is the only advice I can give to people. I'm not for putting a charging limit on it because I sometimes need the full 100% capacity and I don't want to be thinking about my phone's battery all the time, but using a normal USB-A charger doesn't require thinking about all the time.
